Big Sky is the complete shop platform, work orders, FAA-compliant logbook entries, parts inventory and POs, quotes, invoicing with built-in Stripe payments, time tracking, accounting export, and a real-time shop floor view. This guide is the manual.
Use the search box at the top of the sidebar to find any topic in seconds. Every section has a #anchor link in the heading: copy it to share a deep link with another tech in the shop, or with us in support.
Tip: Cmd / Ctrl + F focuses the guide search instead of the browser's find-in-page. Esc clears it.
Big Sky has five roles. Permissions are layered, Owner can do everything, each role below has progressively narrower access.
Owner owner
Top-level admin. Created automatically for the first user on a fresh deploy. Can promote and demote any other role, including Admin. Only Owner can grant Owner. The shop's identity, billing, Stripe Connect, and outbound email routing are Owner-controlled.
Admin admin
Day-to-day shop management. Creates / edits / closes work orders, invoices, POs. Can manage users (create, edit role within Admin / Management / Tech, deactivate). Can sign off LBEs if they're an A&P. Cannot promote anyone to Owner.
Management management
Same operational rights as Admin minus user management. Useful for shop foremen and lead techs who need to coordinate work and read reports but shouldn't be moving people in and out of the system.
Tech tech
Default for new mechanics. Can punch in / out, view assigned WOs, log labor and parts on discrepancies, write resolutions, and sign off LBEs (when they hold an A&P or IA cert). Cannot edit invoices, POs, or shop settings.
Accountant accountant
Read-only access to the Accountant page (A/R aging, payments, vendor bills) plus QuickBooks CSV export. No access to maintenance records or sign-off. Use this for an outside bookkeeper.
Roles change in real time. Demote a user from Admin to Tech and their next page load won't show the Admin tile. No re-login required.
Aircraft are owned by customers. Manage them on the Aircraft page.
Click + Add Aircraft.
Type the tail number, the FAA registry lookup autofills make, model, year, serial number, engine count and engine identity.
Pick the customer (owner) from the dropdown.
Save.
Single-engine vs multi-engine vs APU
The aircraft's engine count drives whether the WO sign-off prompts for separate engine LBEs. Single-engine aircraft sign one airframe LBE that covers airframe + engine; multi-engine aircraft can sign separate LBEs per engine, plus APU if equipped. Tag has_apu on the aircraft to enable APU sign-off.
Click any tail to land on the aircraft detail page. Shows:
Identity (tail, make, model, serial, year), engine and APU info.
Time-in-service: TTAF, Tach, Hobbs, landings, most recent values from the latest WO.
Complete WO history for this aircraft, every LBE that's been signed against it.
Tagged documents (8130-3s, training records) attached to this aircraft specifically.
This is your one-stop view when a customer asks "what was done last annual?", every LBE links to its source WO with the full discrepancy + parts breakdown.
A discrepancy is a single squawk, one defect or task. Most WOs have several. Each one rolls up its own labor + parts cost.
On the WO detail page, click + Add Item.
Pick the section: airframe, engine 1, engine 2, or APU.
Write the squawk in the customer's own words: "Left main tire worn below wear indicators."
When you've done the work, fill in the resolution: what was actually done, IAW which manual reference, with what part and serial numbers.
Optionally enter ATA code, estimated hours, or a labor rate override.
Save.
Resolution is required to sign off. The Sign Off button stays grey until every unsigned discrepancy has resolution text. If sign-off is greyed out, that's almost always why.
Each discrepancy can have any number of parts. Pull from inventory or enter free-text parts you don't stock.
On a discrepancy, click + Add Part.
Start typing the part number, the typeahead matches your inventory. Pick from the dropdown to autofill description, unit cost, markup, and stock count.
For serialized parts, the serial-number field also typeaheads from your serialized inventory. Picking a serial decrements that specific unit from stock and stamps it onto the LBE.
Set quantity, save.
Stock decrement
Pulling a part from inventory automatically decrements the on-shelf count. Removing the part from the disc reverses the decrement.
Free-text parts
Type a part number that doesn't match anything in inventory and the system saves it as-is. No inventory_id is captured: so stock isn't decremented. Useful for one-off parts.
Hours go on each individual discrepancy in the Actual Hours field: that's what shows up on the LBE and the invoice. For shop-wide time tracking that aggregates payroll, see the Time Clock.
Two ways to log:
Direct entry: type hours into the disc's Actual Hours field. Use this when you tracked time off-system.
Time Clock: punch in / out against a specific WO and disc. The aggregate hours roll up to weekly timesheets for payroll, and the per-disc hours show on the LBE / invoice. See Time Clock.
Big Sky has soft edit locks, when a user opens a WO for editing, no one else can edit the same WO at the same time. Prevents two techs blowing away each other's changes.
If you see "Bob is currently editing this work order":
Wait for Bob to finish, OR
Ask Bob to release his lock, OR
Admin / Owner only: override and take the lock anyway (Bob will get a notice that his edits are out of sync).
Locks expire automatically after 30 minutes of inactivity, so abandoned tabs don't permanently block anyone.
From the WO header, click 🖨 Print WO. A clean printable view loads with all discrepancies, parts, and totals laid out for paper. Customer-facing, no internal notes or labor rates by default.
This is what tech writeup, customer copy, and the work-on-the-aircraft printout all look like. Same template; toggle "Show internal notes" if you want it for shop floor use.
Sign-off creates a logbook entry (LBE), locks the WO, and produces a tamper-evident PDF that's ready to hand to the customer or paste into the airframe logbook.
Make sure every discrepancy has a resolution.
Click ✓ Release WO on the WO page.
Pick the section (airframe / engine 1 / engine 2 / APU). The first eligible section is preselected.
Pick the FAR citation: 43.9 (maintenance/alteration) or 43.11 (inspection).
Confirm TTAF / cycles / Tach / Hobbs at sign time. These freeze on the LBE.
Optionally override the RTS statement.
Re-enter your password to authorize the e-signature (per AC 120-78B).
Click Sign & Create LBE.
What happens next: the WO transitions to released, every disc is signed and locked, an LBE row is created with a SHA-256 record hash, and the LBE PDF auto-attaches to the WO Documents library.
Use for any maintenance or alteration work: R&R, troubleshooting, AD compliance, repairs, modifications. The vast majority of work orders.
FAR 43.11: Inspection
Use for the airworthiness inspection itself: annuals, 100-hour, progressive, pre-purchase. The inspection record cites 43.11 and includes the inspection type. If your annual also includes a list of items repaired, you can sign one 43.11 (the inspection) and one 43.9 (the work that fell out of the inspection), that's standard practice.
When you've worked on more than one logbook (airframe + engine 1 + engine 2 + APU), each gets its own LBE.
The WO sign-off flow lets you sign each section separately. The WO doesn't transition to released until every eligible section is signed. Engine LBEs surface engine make/model/serial in the meta grid (frozen at sign time). APU LBEs do the same for APU identity.
Made a typo or need to correct after sign-off? Use Void & Revise. Available from the WO detail page (when status=released) and the LBE detail page itself.
Click Void & Revise in the signed banner.
Enter a reason (required for the audit trail).
Re-enter your password.
Submit.
What happens: the WO returns to in progress, every discrepancy is unsigned and editable, the LBE row is deleted. An immutable audit-log entry preserves the original SHA-256 hash and your reason. After corrections, re-sign to produce a new LBE.
Every signed LBE includes a SHA-256 hash computed over the canonical record at sign time. The hash is printed on the LBE PDF and stored in the database.
Click Verify Hash on the LBE detail page to recompute and compare. Match → record intact. Mismatch → flag immediately, the record has been modified since sign time.
Per AC 120-78B, this is the tamper-evidence mechanism that lets you defend the LBE in any FAA audit.
The Documents library is your shop's complete paperwork archive, 8130-3s, signed LBE PDFs, training records, manuals, photos, customer-supplied PDFs.
Each document can be tied to a customer, an aircraft, a WO, or none of those (general shop docs). Filter by type, search by name / part number / serial number.
After sign-off, the green 📦 Generate RTS Package button appears. Click it to produce a single merged PDF with everything the customer needs.
What's in the package
The signed Logbook Entry (auto-attached on sign-off).
Every 8130-3 tagged for RTS.
Parts Releases (EASA Form 1, TC, DER).
Service Records.
CAMP / MSP cards.
Training records, manuals, anything else with the RTS toggle on.
The merged PDF downloads with archival metadata. Hand it to the customer; they have a single document with every airworthiness record for this trip through the shop.
Once the customer says yes, click Convert to Work Order. A new WO is created with the quote's items pre-populated as discrepancies and parts. The quote is marked accepted with a link back to the new WO.
From the invoice detail page, click Send Invoice. We email the customer the invoice PDF + a Pay Now link.
The Pay Now link takes them to /pay?invoice=…: a public page where they can view the PDF, pay with a card, or read your wire/check instructions for offline payment. Invoice flips to sent.
From the invoice detail page, click Download PDF. A clean printable PDF generates server-side with shop letterhead. For paper invoices, hit Print directly, same template renders cleanly on letter-size paper.
When a customer hits Pay Now, Stripe collects their card and processes the charge. As soon as Stripe confirms, the invoice flips to paid automatically.
You'll see the payment in the Stripe dashboard within seconds and on the Accountant page's payments view immediately. Stripe pays out to your bank on whatever schedule you've configured (daily / weekly).
Issue refunds in the Stripe dashboard, full or partial. The Big Sky invoice updates to reflect the refunded amount automatically via webhook.
For check / wire payments that need to be reversed, void the manual payment record first, then issue the refund out-of-band and record it as a separate credit memo.
The Parts Manager is your parts shelf. Each row is a part number with description, on-shelf count, unit cost, sale price (or markup %), and optional reorder threshold.
Click + Add Part.
Enter part number, description, unit cost, and either a sale price or markup %.
Set on-shelf quantity. You can adjust this any time.
Optionally set a reorder point: the dashboard surfaces parts at or below this number.
Parts are searchable from the WO Add-Part typeahead, which makes adding them to discrepancies a one-click affair.
For parts that need serial-number traceability (life-limited engine components, avionics, anything tagged), enable serialized tracking on the part. Each individual unit gets its own serial stored alongside inventory.
When you add the part to a discrepancy, the serial-number field becomes a typeahead of in-stock serials. Pick one; that specific unit gets pulled from inventory and stamped onto the LBE.
When you swap a unit and the old one goes back to the vendor for core credit, log it on the Cores page.
The system tracks expected return dates, credit amounts, and which WO/PO the core came from. The dashboard surfaces overdue cores so they don't fall off the radar.
From the PO detail page, click Receive. Same flow as Parts Receiving, confirm quantities, upload the 8130-3, save. Inventory updates and cost rolls to the WO.
POs auto-close when fully received. To reopen a closed PO (received quantity wrong, vendor sent more, etc.), an Admin or Owner can Unlock or Reopen the PO from its detail page. Tech / Management cannot, preserves audit trail integrity.
The Status Board is a real-time read of the shop floor. Designed to be cast to a wall-mounted TV or a large monitor in the lobby.
Shows every active WO grouped by status (Open / In Progress / Waiting Parts / Complete) with the tail number, customer, assigned tech, and time-in-shop. Auto-refreshes, no manual reload.
Tip: Customers love seeing their tail on the board. It signals "you're being worked on" and reduces "any update?" phone calls dramatically.
Open punches show at the top of the page in real time so you don't forget to clock out. Each tech's weekly hours roll up; Management approves; payroll exports to CSV with FLSA-aware overtime calc.
Work Authorization is the customer-signed pre-work contract. Generates a clean PDF the customer can sign on-screen (touchscreen or mouse), in person or remotely.
Pulls customer + aircraft info from the WO.
Includes your standard terms (editable in My Shop → Work Authorization template).
Customer types name + signs on canvas.
Saved as a PDF, attached to the WO Documents library with type=work_auth.
Work Auth is NEVER bundled into the RTS package by design. It's a pre-work contract, not airworthiness evidence. The system enforces this regardless of how the RTS toggle is set.
Inspection Library holds reusable inspection checklists keyed to aircraft make/model.
Build a template once for the C172 annual; pull it into every C172 annual WO with one click. Templates are the difference between an annual taking 8 hours of paperwork prep and 30 seconds.
The Accountant page is the bookkeeper's home base. Built for an outside accountant or in-house finance person who shouldn't have access to maintenance records.
Billing pipeline: every released WO not yet invoiced. Click to invoice.
Customer Invoices: every invoice with status, age, payment method.
Payments & Reconciliation: full ledger. Reconcile bank deposits against Stripe + manual entries.
Purchase Orders: vendor bills view with overdue highlighting.
A/R Aging: current / 30 / 60 / 90+ buckets with totals.
From the Accountant page, the QB Export card produces a CSV in QuickBooks Desktop's import format.
Pick a date range, choose what to include (invoices / payments / vendor bills), download. Import into QB once a week or once a month, whatever your bookkeeper prefers.
The export includes customer names, invoice numbers, line-item GL codes (mapped on My Shop → Accounting), payment methods, and reference numbers. Bookkeeper-friendly.
My Account is the personal settings page for the currently logged-in user.
Update display name, email.
Change password.
Update or re-draw your signature (used on every LBE you sign going forward).
Update your cert type and cert number if it ever changes.
Frozen on signed LBEs. Updating your signature does NOT change anything you've already signed, those PDFs are tamper-evident and the signature is baked in. New LBEs you sign from this point use the new image.
Every part can have a free-text shelf label, "B-12, Bay 3" or "Rack 4, Avionics", separate from which warehouse it lives in. Set it in the Edit Part modal under Bin Location.
The label shows up as a 📍 chip on the Parts Manager row so a mechanic can find the bay without asking parts admin. This is per-part metadata, not per-warehouse, use Stock Locations (below) to track which warehouse a part is in.
Mechanics can pull parts off the shelf before they've opened a work order. The system tracks every checked-out unit until it's either scanned onto a WO or returned to the shelf.
Why it exists
Stock_levels stay the single source of truth for what's physically on the shelf. Checkouts are an overlay: separate ledger that says "Jane has 2 of these in her toolbox right now." Nothing decrements stock until a part actually gets consumed on a WO.
Three ways to check out
Parts Manager row: click 🔄 Check Out on any row. Pick location, qty, optional WO + notes. Lot-tracked parts also pick a specific lot.
Scanner: scan a part QR, hit "🔄 Check Out to Me (no WO yet)" instead of Log Part Usage. Defaults to your home location automatically.
Admin on behalf: coming soon. Today it's self-service only.
Auto-close
When you later scan the part onto a WO via the normal flow, the system FIFO-decrements your open checkouts for that part. Any leftover qty stays in your list until you return it. If you consume more than you checked out, the extra "falls through" as a normal consume, no harm.
The 🔄 N OUT chip
Parts Manager rows show how many units are currently checked out across all mechanics. Hover the chip to see who has what.
My Checkouts is the mechanic-facing list of every part currently in your possession. Tile is on the dashboard for everyone.
Each row shows part number, qty remaining of qty checked out, when, from which location, optional WO, and any notes.
Return form on every row, enter the qty you didn't use, hit Return. Closes the row when qty hits zero.
Rows older than 7 days get an amber "Stale" tag, it's how admin spots forgotten checkouts.
Tip: If you scanned a part onto a WO and it still shows here, the auto-close didn't match, usually because the lot didn't match or you consumed from a different mechanic's checkout. Just hit Return; the stock is already where it should be.
Stock Locations tracks WHICH warehouse each unit of stock lives in. Big Sky uses three: PBI, MLB, GRANT.
Three types
Warehouse: primary stock points (PBI, MLB, GRANT). Each part has its own per-warehouse qty.
Location: sub-areas inside a warehouse (mostly informational).
Van: mobile stock that travels with a tech.
Hidden locations
One location, GRANT-HIDDEN, is walled off from maintenance, it's the wholesale-only stock for BSAP. Only Owner and Grant parts users see it. See Wholesale & Hidden inventory.
Transfers moves stock between warehouses, and absorbs customer-supplied parts into BSA inventory.
Warehouse-to-warehouse
Source location ships N units of a part.
Destination receives, qty decrements at source, increments at destination.
Print a packing list from the transfer detail page if the parts are being trucked.
Customer → BSA transfer
When a customer brings a serviceable part to a WO and it gets used elsewhere, transfer it into BSA stock under a customer-credit. Recorded as a denial-reason if the customer later asks for it back.
Grant's wholesale-only stock is hidden from the maintenance side so a mechanic can't accidentally pull a wholesale part onto a customer aircraft.
Per-part Wholesale toggle
Edit a part → Wholesale toggle. Moves 1 unit at a time between GRANT and GRANT-HIDDEN. The 🔒 WHOLESALE pill shows on rows with hidden stock, visible only to Grant parts + Owner + Admin.
Who can see what
Maintenance techs, customers, other warehouses, see only non-hidden stock totals.
Owner + Grant parts users, see the full picture including hidden qty and the pill.
Hidden parts can only be sold via Parts Sale WOs (see BSAP).
Parts Requests is the tech-submitted requisition flow. Tech needs a part that isn't on the shelf, submits a request; parts admin approves and turns it into a PO.
Tech: "+ New Request", part #, qty, urgency, optional WO.
Lead signs off (electronic signature), gate that prevents random requisition spam.
Parts admin reviews, approves, denies, or marks ordered.
Approved requests auto-draft a PO so admin doesn't re-type.
The dashboard tile shows a count badge of requests awaiting your action.
BSAP is the wholesale parts arm. Separate Stripe account, separate invoice numbering (BSAP-YYYY-NNNN), separate dashboard.
How it works
Create a Non-MX Parts Sale WO with Payee: bsap. The customer pays Big Sky Aviation Parts LLC, not Big Sky Aviation Maintenance.
Hidden GRANT-HIDDEN stock can be pulled onto BSAP WOs (and only BSAP WOs).
Invoices generate as BSAP-2026-0001… with the BSAP branding and bank details.
Payments route to the BSAP Stripe account, not BSA's.
Parts Sales dashboard
Parts Sales is the BSAP-specific dashboard. Owner and Grant parts users only: admin is denied here, and the page returns 404 to make BSAP's existence private to anyone without access.
RMAs tracks parts you're returning to a vendor, wrong part shipped, defective, etc. The dashboard surfaces open RMAs so credits don't fall off the radar.
Create from a PO line (most common) or standalone.
Core Search Requests is where techs and parts admins can ask the system to scan for a sourceable core internally before going to an outside vendor.
The search includes GRANT-HIDDEN, so a needed core might already be sitting in wholesale stock waiting to be re-routed to maintenance. Saves the shop hundreds when it hits.
73Quality chips (stale prices, max qty, scrap fee) #
Parts Manager rows surface data-quality issues as small chips so admin can fix them in-line.
Chip types
NEEDS INFO: part is missing required metadata (description, cost, threshold, vendor). Hover lists exactly which fields.
STALE price: unit cost hasn't been confirmed in 6 months (or ever). Call the vendor, then hit Confirm Price in the Edit modal to clear.
📍 Bin Location: already covered, the shelf label.
🔒 WHOLESALE N: hidden GRANT-HIDDEN stock. Owner / Grant parts only.
🔄 N OUT: currently checked out across all mechanics.
Max Qty & Scrap Fee
Max Qty on a part caps reorder suggestions (so the dashboard doesn't auto-suggest 50 of a part you only need 5 of). Scrap fee auto-adds a per-WO disposal charge for hazmat / oil consumables, see My Shop → Default scrap fee.
Inventory Audit Log records every change to every stock_level in chronological order. Receive, consume, transfer, cycle-count, checkout, write-off, every event with who, when, before, after.
Filter by part, user, action type, or date range. CSV export for the annual audit binder.
When a tech saves a note on a WO discrepancy, they re-enter their password. The system stamps name + cert + timestamp onto the note so it can serve as evidence of work performed.
Clock-out gate
You can't clock out of a WO unless you've saved at least one note on that WO during the punch. Forces a habit of documenting findings before walking away. Bypass: clock to Shop (indirect) instead of a WO.
When a tech clocks out of a WO, their labor hours push to the WO instantly. When admin later approves the time on the Time Clock Manager, the WO re-syncs with the approved (billable) hours.
Open punch: WO shows nothing yet, just the active timer.
Clocked out, not approved: WO shows the duration with a yellow "Pending approval" badge.
Approved: WO shows approved hours with a green badge. Invoice calculations use the approved number.
If admin rejects (rare) or trims hours, the WO updates back to the trimmed total.
Big Sky services aircraft at every airport in Florida. Travel Baselines defines the expected drive time + miles to each airport. When a tech logs travel that significantly exceeds the baseline, the system auto-flags it for admin review.
Workflow
Owner / Admin sets baselines for each airport (one-time setup; we seeded all FL airports).
Tech logs travel time on a WO. System compares actual vs. baseline.
If overrun > threshold, the punch is flagged automatically.
Admin reviews on Time Clock Manager → Travel Flags card: mark OK (legitimate reason), Stolen (follow up), or Follow-up (later).
Tip: Don't punish honest overruns, traffic, fuel stops, weather. The flag exists to make patterns visible, not to ding any single punch.
A Parts Sale WO is a non-maintenance WO where Big Sky just sells parts (no labor, no airworthiness). Lower-touch than a full MX WO.
Auto-COC
When you close a Non-MX Parts Sale WO, the system auto-generates the BSA Certificate of Conformity form, the document the customer needs for their records. Attaches to the WO Documents library automatically. No more hand-filling COCs.
Hidden stock allowed
Parts Sale WOs are the only WO type that can pull from GRANT-HIDDEN. Combined with Payee: bsap, this is the BSAP wholesale flow.
For international customers, generating a standard invoice isn't enough, customs requires a commercial invoice with HTS codes, country of origin, and a value declaration.
Mark the customer as international in their profile (sets the default for every invoice).
Per-line: HTS code, country of origin, declared value.
Print uses the commercial invoice template, customs-acceptable layout with shipper/consignee blocks and signature lines.
Standard invoice still generates in parallel for the customer's accounting.
Tooling tracks every shared tool in the shop, calibrated and uncalibrated alike. Different from Tool Calibration: Cal tracks the gauge / wrench cal-due dates, Tooling tracks who has it right now.
Workflow
Add each tool with name, serial / asset tag, photo, optional cal certificate.
Print a QR sticker from the tool detail page; stick on the tool.
Tech scans QR on the Scanner, page offers "Check Out to Me" or "Return".
2FA is admin-enrolled, SMS-based, mandatory for Owner and Admin accounts. Users can't turn it on or off themselves, only Admin / Owner can enroll or disable.
Enrolling a user
Admin / Owner: Admin page → pick a user → 2FA section → enter their mobile in E.164 format (+15615550100).
User receives a 6-digit enrollment code. They read it back to admin.
Admin enters the code. 2FA flips on; the user gets a confirmation SMS welcoming them to the campaign.
Admin captures the 10 one-time recovery codes that appear, these are returned once. Save in a password manager.
Signing in with 2FA
Normal password sign-in → second screen prompts for the SMS code. Code is valid for 5 minutes. Recovery codes can be used in place of an SMS code if the phone is lost.
Disabling
Admin / Owner can disable 2FA on a user's account (e.g., phone lost permanently). They should re-enroll under a new number rather than leave it off long-term.
Mandatory for Owner + Admin. The system enforces it server-side, privileged accounts can't bypass 2FA even if it's "off" in their record.
Users can sign in with their work Microsoft / Azure AD account instead of a JMGMT password. Alternative to (not replacement of) password sign-in.
Setup
Owner registers the app in the company's Azure tenant (one-time, ~10 min).
Each JMGMT user's account needs their work email set in Admin; SSO matches by email.
Login page shows a "Sign in with Microsoft" button.
How it interacts with 2FA
SSO-signed users still hit the 2FA gate if they have 2FA enrolled. Most shops just rely on Microsoft's MFA at that point and turn off the JMGMT-side 2FA for SSO users, your call.
Every login attempt, success or failure, captures coarse geolocation (from the browser, with permission), IP address, and user agent. Visible on the Time Clock Manager → Login Locations card.
Filter to failures-only to spot brute-force attempts.
Filter by user to see where one specific person logs in from.
Filter by time window: 24h, 3d, 7d (default), 30d.
The geo permission is requested at the login page so it's there before sign-in. If the user denies geolocation, login still works, just no map pin.
JMGMT publishes /privacy.html and /terms.html as public pages, reachable without sign-in. They're linked from the login page footer and used by Twilio for A2P 10DLC SMS campaign registration.
Update text in the HTML files. Both pages cover JMGMT operationally + the specific SMS data-sharing language Twilio carriers require. Don't edit the "We do not sell, share, transfer…" mobile-number paragraph without re-registering the SMS campaign.
Almost always: at least one discrepancy is missing a resolution. Open each disc, fill in the resolution text, save. The button activates as soon as every unsigned disc has resolution text.
Other reasons: you don't have a signature or cert number on file (My Account), or you're a role that can't sign (Tech without an A&P / IA cert, Accountant always).
Any checkout open longer than 7 days gets an amber "Stale" tag on My Checkouts and shows up on the admin's Time Clock Manager → Stale Parts Checkouts card.
If the parts are still in your toolbox waiting on a job: ignore, the tag is informational. If you used them but didn't scan onto a WO: scan now, the auto-close will clear it. If you don't know where they are: tell admin so they can write it off rather than leave it open.
Hidden GRANT-HIDDEN stock is only visible to Owner and Grant parts users, by design. If you're a maintenance tech, you shouldn't be pulling wholesale stock onto a customer aircraft.
If you genuinely need a part that's only in wholesale: file a Core Search Request. If the system finds it in hidden stock, parts admin can move 1 unit back to maintenance via the Wholesale toggle on the part's Edit modal.
