Quote on the driveway. Invoice before you pack up the van.

The best mobile mechanic software for an Australian sole operator handles the whole van-to-invoice loop in one place — on-site jobs, kerbside quoting, GST invoicing, vehicle records and on-the-spot payment — instead of stitching together a job app, a separate invoicing tool and a spreadsheet of customer cars. Tradify, ServiceM8 and Fergus are capable field-service apps, but a car is just another generic job line and you still bolt on Xero for accounting and a booking page elsewhere. OneBookPlus is built around the vehicle and the mobile workflow: quote on the driveway, invoice before you pack up the van, take payment on the spot, and keep VIN-keyed service history — all on one platform from $0/month. When you compare, look at the all-in monthly cost, not just the job-app price.

Yes — the free plan includes invoices, quotes and a small set of clients, which is plenty to run as a sole-trader mobile mechanic getting started. You get a branded booking page, GST and ABN on every invoice, and the mobile app for quoting and invoicing from the van. Upgrade to Starter or Growth when your job volume justifies unlimited invoices, payments and a customer list.

Yes — that is exactly what OneBookPlus is built for. Open the app at the kerb, enter or scan the VIN to auto-fill the vehicle details, build an itemised quote with labour, parts and a callout fee, and the customer taps Accept on their own phone. When the job's done, convert the quote to a GST-compliant invoice with one tap and send it before you leave. Everything works on your phone, including taking a card payment.

Customers can pay straight from the invoice link by card or bank transfer. On supported iPhones, Tap to Pay lets you accept a contactless card or phone payment using only your phone — no separate terminal in the van. Card payments are processed by Stripe (processing fees apply), and bank transfers via the pay link reconcile back against the invoice automatically, so you're not chasing the money next week.

Yes. Every quote and invoice automatically calculates 10% GST and displays your ABN, meeting ATO tax-invoice requirements. Labour, parts and callout fees are itemised separately. At BAS time you export a GST summary — GST collected on invoices and GST credits on parts and expenses — in one click to hand to your accountant. Note that you only charge GST if your business is registered for GST (required once turnover reaches the ATO threshold; optional below it).

Yes. OneBookPlus keeps a customer-vehicle directory indexed by rego and VIN. Decode the VIN to auto-fill make, model, year, engine and transmission, then every job, photo and invoice attaches to that vehicle. Next time the customer calls, you can see exactly what you did last visit and what you flagged to watch — so you quote the right parts and look like you remember their car.

Roadworthy and safety inspections (VIC Roadworthy Certificate, NSW pink-slip e-Safety, QLD Safety Certificate and the equivalents in other states) can generally only be issued by a licensed tester or accredited inspection station — most mobile mechanics aren't set up to issue them on-site. OneBookPlus does give you a digital inspection checklist with photo evidence for pre-purchase and condition reports you can hand a customer, and you can attach any certificates you are licensed to issue to the vehicle and job record. Always follow your state regulator's rules on who can perform and lodge a statutory inspection.

Yes, with an automotive focus. ServiceM8, Tradify and Fergus are general field-service apps that dispatch generic jobs well, but a vehicle is just another job to them and you still add Xero for accounting and a separate booking page. OneBookPlus is built around the vehicle and the mobile workflow — VIN-keyed service history, kerbside quote-to-invoice, on-the-spot payment, plus accounting, marketing and reviews on the same data. For a mobile mechanic who wants vehicle records rather than generic job cards, it replaces the job app and the accounting tool together, from $0/month.
