Per-repair parts records for mobile and independent mechanics
Doing repairs in driveways means a parts-store run for every job — brake pads for one car, a filter and fluids for another, shop rags for the truck. If the parts aren't linked to the customer and vehicle, the repair invoice comes up short and you can't pull the history when they call back. Cash Workspace gives you one place to record each parts run against the customer and the vehicle, with the invoice attached.
The problem
Why mechanic parts costs get lost
Parts come from several stores per day, customers have specific vehicles, and shop supplies blend in. Without records linked to the repair, parts and proof scatter.
- One parts-store invoice covers brakes for one car and a filter for another.
- Fluids and small parts pulled from truck stock never make the invoice.
- You can't pull the part numbers when a customer returns with the same car.
- Shop supplies like rags and cleaner blend in with billable parts.
- A new tool purchase gets mixed in with consumables you rebill.
The workflow
Record each parts run against the repair
Link every part to the customer and vehicle while the car is still in front of you.
- 1
Record at the parts counter
After a run, record the vendor, date, and amount and attach the invoice before the next job.
- 2
Link customer and vehicle
Note the customer and the vehicle — 'Nguyen — 2014 Civic, front brakes' — so parts map to the repair.
- 3
Note part numbers
Add key part numbers so you can reorder or reference them on a callback.
- 4
Separate parts, supplies, and tools
Tag billable parts apart from shop supplies and one-time tool purchases.
- 5
Pull at invoice time
Open the repair's parts records when you bill so every part lands on the invoice.
Record structure
What to record for each parts purchase
These fields tie parts to the right vehicle and keep them findable on a callback.
- Parts vendor
- The parts store, dealer counter, or online supplier.
- Date
- When the run happened, so it files into the right month and repair.
- Amount
- What you paid for the parts on this record, including tax.
- Part type
- Filters, brakes, fluids, belts, or sensors — plus key part numbers.
- Customer and vehicle
- Who and which car (year, make, model), so parts map to the repair.
- Category
- Billable part, shop supply, or tool purchase.
- Invoice
- The parts-store invoice attached to the record.

Common mistakes
Mistakes to avoid
- Not linking parts to the vehicle, so callbacks mean guessing what was installed.
- Forgetting to bill fluids and small parts pulled from truck stock.
- Mixing shop supplies with billable parts on one record.
- Tagging a one-time tool as a job consumable, which muddies billing.
- Skipping part numbers, so reorders and references take longer.

FAQ
Mobile mechanic parts records FAQ
- Why link parts to the specific vehicle?
- When a customer calls back about the same car, the vehicle link lets you pull exactly which parts and part numbers you installed. It turns each repair into a history you can reference instead of guessing.
- How do I keep shop supplies from inflating a repair?
- Tag rags, cleaner, and other shop consumables in their own category, separate from the billable parts for a job. That keeps each repair's parts cost accurate and your supply spending visible on its own.
- Does Cash Workspace read my parts invoices?
- No. You enter the vendor, date, and amount and attach the invoice. Cash Workspace keeps the record and the invoice together against the customer and vehicle so parts are easy to match to the repair.
