Auto parts inventory software for repair shops.
Most shops run parts inventory out of Excel or bolted onto general accounting software — and it falls apart the same way: the system says a part's in stock, the shelf says otherwise. ShopOS's auto parts inventory software tracks parts in real time, tied to the repair order they're going on, so the system matches the shelf.
Real-time stock, not a spreadsheet someone forgot to update.
A spreadsheet is accurate the moment someone updates it — and wrong every moment after. Parts in ShopOS update the moment they're received, used, or ordered, so the count on screen matches the shelf.
- Built for repair shops, not parts resellers — the same system as your repair orders, not a bolted-on retail tool
- Your existing parts catalog comes across during onboarding, not typed in from scratch
Low-stock alerts before a job stalls waiting on a part.
Nothing stalls a repair order like discovering mid-job that a part everyone assumed was in stock isn't. Low-stock alerts catch that before the tech is standing at an open hood waiting on you.
Alerts before a commonly-used part actually runs out, not after
Flags slow-moving stock tying up cash on the shelf
Visibility into what to reorder before it becomes a same-day emergency
Purchase orders tied straight back to the part you needed.
Create a purchase order from a low-stock alert, and when the part arrives, receiving it against that PO updates your stock automatically — no separate step to reconcile what showed up against what was ordered.
- Track PO status — what's ordered, what's still outstanding
- Full order history tied to the part — what was ordered, when, and at what cost
Know your cost and margin on every part.
Inventory isn't just a stock count — every part carries its real cost and markup, not just a sell price. That's what drives the pricing on estimates and invoices: the real margin on that part, not a number typed in on the fly.
- Margin visible per part, not just guessed at across the whole shop
- Update a part's cost once, and every future estimate reflects it — no stale pricing
Parts go straight onto the estimate or invoice — no re-typing.
Adding a part to a job shouldn't mean looking it up twice — once in inventory, once on the estimate. In ShopOS, a part added to a repair order pulls its price and availability straight from inventory and carries onto the invoice the same way.
- Add parts directly from the repair order screen — no separate inventory lookup
- Price and stock status pulled in automatically, not re-typed
- Same part record carries from estimate through to the final invoice
Frequently asked questions
Why does my inventory show parts in stock that aren't actually on the shelf?
Usually because stock counts are only updated manually, so anything sold, used, or received off-system doesn't reflect until someone does a recount. ShopOS updates stock automatically as parts move through a repair order, so the count stays tied to what's actually happening in the shop.
What is auto parts inventory software?
It's automotive parts inventory management built into your repair-order system — instead of tracking car parts in a separate spreadsheet or a retail tool, stock, cost, and reorders live where the jobs are.
How do I know which parts to keep in stock?
Low-stock alerts flag commonly-used parts before they run out, based on how often they're actually used on repair orders — not a guess or a fixed reorder list that goes stale.
Can I order parts directly from the repair order screen?
Yes. Parts get added straight from the repair order, pulling current price and stock status, instead of switching to a separate inventory screen to look them up.
Do I have to re-enter my whole parts catalog to switch to ShopOS?
No — your existing parts catalog comes across during onboarding, so you're not starting from zero or retyping every part by hand.
