How we picked
Entry prices as published by each vendor in 2026. We judged tools on the mobile mechanic's actual workflow — quote, invoice, get paid on-site — not on parts-catalog depth.
| Software | Starting price | Best for |
|---|---|---|
| ShowTheReceipts That's us | $15/mo | Labor-first invoicing, on-site card, cash & Venmo tracked, tax-ready books |
| ARI | $39.99/mo | Parts inventory, VIN decoding, repair templates |
| Orderry | from ~$39/mo | E-signatures and approval workflows on-site |
| Jobber | $49/mo (Core) | Mobile crews needing scheduling + dispatch |
| Invoice2go | from ~$10/mo | Bare-bones invoices, nothing else |
The core workflow question: Labor-first vs. full parts catalog
Choosing the right invoicing tool as an independent mobile mechanic comes down to how your daily repair work is structured:
- Labor-First Mobile Operations (80% of independent mechanics): Your jobs consist of on-site diagnostic service calls, brake replacements, starter/alternator swaps, oil service, battery replacements, and minor bolt-on repairs. You buy parts on-demand per job or install customer-supplied parts. For this model, an intuitive, labor-first app like ShowTheReceipts gets you paid on-site in 30 seconds without paying for complex parts inventory features you don’t use.
- Complex Repair & Parts-Catalog Operations (20% of mechanics): You carry $5,000+ in vehicle parts inventory in your service van, require automated VIN decoding, use OEM flat-rate labor time manuals (Mitchell 1 / ALLDATA), and issue multi-page warranty repair orders. For this model, dedicated automotive shop management software like ARI is designed for that specific depth.

Essential features for mobile mechanics billing on-site
When evaluating invoicing software for your mobile repair rig, ensure it supports these crucial operational workflows:
- Diagnostic Surcharge & Written Estimate Approvals: Always charge an initial diagnostic fee ($75–$150) that can be applied toward the total repair cost once approved by the customer.
- Parts Markup Transparency: Standard parts markup ranges from 25% to 50% above wholesale cost. Ensure your invoicing app allows you to easily adjust line-item markups without exposing supplier costs to the customer.
- Roadside Call Surcharges: Include distinct line items for emergency roadside calls, mileage fees, or after-hours service to protect your labor margins.
Frequently asked questions
What app do mobile mechanics use for invoicing?
It depends on how much parts complexity is on the invoice. If it's mostly labor with a short parts list, ShowTheReceipts at $15/month covers it — quote, invoice, and take payment on-site with no parts catalog to configure. If you need VIN decoding and a full parts inventory on every invoice, that's a narrower, more expensive category of tool.
When would ShowTheReceipts not be enough for a mobile mechanic?
Only if you carry parts inventory, quote from repair templates, or need vehicle history on every invoice — that's a real, narrower need specialized auto-repair software covers. If your invoice is 'brake job: labor + pads,' ShowTheReceipts covers the same quote-to-paid loop at $15/month without paying for a parts catalog you won't use.
How should a mobile mechanic take payment?
On-site, at completion — card via tap-to-pay or a payment link by text, with cash and Venmo recorded in the same ledger. Mobile repair without same-day collection turns into a receivables business fast.
