What invoicing app do mobile mechanics use?
Mobile mechanics use SMASH to invoice diagnostics, servicing, roadside call-outs, labour, parts markup, fluids and fleet work without typing it all after hours. Save your hourly rates, call-out fees and common parts once, then describe the job by voice from the driveway or create a quote from Gmail. SMASH builds the GST-compliant invoice, separates labour and parts, adds the payment link, and can sync it to Xero or QuickBooks.
The mobile mechanic invoicing problem
Sound familiar? You're not alone.
Parts and labour on every invoice
Oil, filters, pads, batteries, fluids, diagnostics and labour all need detail, but typing them into a phone in a driveway is slow.
Parts markup gets guessed
The difference between cost, markup and retail price gets fuzzy when you are working from memory at the end of the day.
Call-out and roadside rates vary
Standard driveway jobs, urgent breakdowns and fleet call-outs need different fees and terms.
Customers approve work on site
Extra repairs are agreed verbally, then the final invoice needs to show what changed and why.
Fleet work needs clean records
Vehicle registration, job notes, service items and account terms need to be clear enough for a fleet manager to approve.

Built for the trade
Built for how mobile mechanics run
Labour and parts itemised
Describe the repair once. SMASH separates diagnostics, labour, parts, fluids and consumables so customers can approve the charge.
Parts markup and materials pricing
Save common parts and markup rules for batteries, filters, fluids, pads, rotors and consumables. Mention them by voice and SMASH prices them.
Call-out and roadside fees
Save standard, after-hours, roadside and fleet call-out rates. Say which applies and SMASH uses the right fee.
Vehicle and fleet records
Keep customer, vehicle, rego, service history, terms and repeat rates together for faster fleet invoicing.
Quote to invoice
Send a quote for larger repairs or Gmail enquiries, record approval, then convert the approved work into an invoice.
