Record an expense (OWNER)
GarageManager tracks your costs where they actually happen — on the parts you sell. Rather than a separate expense ledger, you record what a part costs you against the part itself, and GM carries that cost onto every job the part goes on. That is what turns revenue into profit you can see.
Record a part’s cost
- Open Settings → Library and find the part.
- Set its cost price — what you pay the supplier — alongside its sell price.
- Save. From now on, when that part is added to a quote or invoice, GM snapshots the cost onto the line.
Owner and Admin only. Cost prices and suppliers are visible and editable only to the Owner and Admins. Managers and technicians never see them, so your margins stay private. The Expenses and profit views are Owner-only.
Why cost lives on the part
Because the cost is snapshotted onto each line at the moment it’s added, a later supplier price change doesn’t rewrite the profit on jobs you already did. Last month’s margin stays last month’s margin. It also means cost flows automatically — you cost the part once, not on every invoice.
Once parts carry costs, see the result in Tracking parts cost on invoices and the month-to-date profit widget.
