Invoicing & Business Software for Tradies

If you're a plumber, sparkie, builder, or painter running your own show, you already know the drill — you're juggling ServiceM8 for job management, Xero for invoicing, Calendly for bookings, and maybe a spreadsheet or two to keep track of materials and expenses. Each tool costs money, none of them talk to each other properly, and you end up doing admin at 9pm instead of watching the footy. OneBookPlus replaces the lot with a single app built for how Australian tradies actually work — on-site, on your phone, between jobs.

The platform covers the full job lifecycle from first contact to final payment. A customer finds you through your OneBookPlus booking page (or you add them manually after a phone call) and you create an itemised quote right there on your phone — labour, materials, travel, GST calculated automatically. The customer gets a professional PDF with your ABN, logo, and payment terms. They accept with one tap. The accepted quote converts into a scheduled job on your calendar, assigned to you or one of your team. When the job's done, you convert the quote to a GST-compliant invoice with a single tap and send it before you've left the driveway. The customer pays online via the invoice link. Done.

Your Daily Workflow

Picture a typical Tuesday. You check the OneBookPlus dashboard at 6:30am over a coffee — three jobs scheduled, one quote awaiting response, and a service reminder flagged for a customer who's due for their annual hot water check. You confirm the reminder with a tap and it queues a follow-up email. Your apprentice opens his phone and sees his two assigned jobs with addresses, client notes, and scope of work. You arrive at your first job, diagnose a blocked drain, snap a photo for your records, and create a quote for $420 including materials. The customer accepts on the spot. By 10am the job's done, the invoice is sent, and you're driving to job two. At the end of the day you check your dashboard: $1,800 invoiced, two payments already received, expenses logged with receipt photos from Bunnings and the fuel station. No evening paperwork.

Bank Feeds & Accounting

OneBookPlus connects to your business bank account and pulls in transactions automatically. When a customer pays an invoice, the system matches the payment to the invoice for you — no manual reconciliation. Expenses you've logged (materials, fuel, insurance, ute repayments) are categorised and tracked against revenue so you can see your real profit margins, not just what you invoiced. GST is calculated on every invoice and expense automatically. When BAS time rolls around, you export a clean GST summary — GST collected, GST paid, and the difference you owe or are owed — and hand it to your accountant or lodge it yourself. No more shoebox of receipts.

Getting Started

Sign up in under a minute — no credit card required. Add your ABN, upload your logo, and set your payment terms. Import existing clients from a spreadsheet or add them as you go. Most tradies send their first quote within ten minutes of signing up. The free plan covers unlimited invoices and quotes with up to five clients, so you can try it on real jobs before committing. When you're ready for bank feeds, team management, or more clients, upgrade to a paid plan — still a fraction of what you'd pay for ServiceM8 plus Xero plus Calendly combined.
