Parts inventory built for auto repair shops
A shop that doesn't track parts inventory loses money three ways: forgotten parts (invoiced at zero), miscounted stock (surprise re-orders that stall a job), and eroded markup (parts sold at cost because the invoicer didn't know the real price). Glo Invoice's parts catalog fixes all three by tying inventory directly to the invoice.
Every part on the catalog has a cost, a sell price, a markup rule, and a quantity on hand. Invoicing a job decrements stock automatically. Reorder alerts fire at your threshold. Reports show margin by part, by month, by tech.
How Glo Invoice does it
Cost, sell, markup, quantity — per part
Every part tracks cost from your supplier, sell price to the customer, markup rule (percentage or fixed), and quantity on hand. Update cost when the supplier raises prices and every future invoice reflects the new margin.
- Per-category markup (OEM vs aftermarket vs consumables)
- Bulk cost update from supplier CSV
- Cost-vs-sell margin visible on every invoice line
Stock decrements on invoice, not on quote
Estimates don't move inventory. Invoicing the job does. That means a quote sitting in a customer's inbox doesn't lock up stock, but the moment you invoice, the parts are gone from your count and the reorder alert fires if you're below threshold.
- Stock decrement on invoice creation
- Reorder alert at custom threshold per part
- Reversal on invoice void or credit note
Core charges, returns, and shop supplies
Core charges bill as their own line at time of sale and reverse as a credit when the core is returned. Shop supplies bill as a percentage or fixed amount per job. Nothing is hidden in labor.
How it works
- Step 1Import your parts catalog
CSV import from your supplier or spreadsheet. Map columns to cost, sell, quantity, category.
- Step 2Set markup rules per category
OEM 25%, aftermarket 40%, consumables at fixed price. Rules auto-apply on new parts.
- Step 3Invoice — stock decrements
Every part on the invoice comes off inventory automatically. Reorder alert if below threshold.
- Step 4Report on margin monthly
See margin by part, category, tech, and month. Adjust markup where it's slipping.
Which shops use it
Independent auto repair shops, tire and alignment shops, diesel and heavy-duty repair, motorcycle shops, marine service, and mobile mechanics who carry a truck-stock inventory.
