Built for Australian Tradies
Quoting, invoicing, scheduling, and getting paid — all from your phone. Built for plumbers, electricians, builders, painters, and every Australian tradie who'd rather be on the tools than doing paperwork.





Everything You Need
Forget clunky desktop software. OneBookPlus is the tradie invoice app designed for blokes and sheilas who work with their hands — not behind a desk.
Create and send professional, GST-compliant invoices from your phone the moment the job is done. No more chasing paperwork when you get home.
Send itemised quotes to customers in minutes. They can accept with one click, and you can convert accepted quotes straight into invoices.
See your entire week at a glance — all scheduled jobs by day, who's assigned to what, and in-progress work that needs attention. Assign jobs to specific techs and track the pipeline from Quoted through to Invoiced.
Automatic GST calculations on every invoice. Export GST summaries at BAS time so your accountant loves you. ABN displayed on all documents.
Assign jobs to individual tradies on your team. Each tech sees their own jobs for the day. Reassign from the job detail if plans change — no group chats needed.
See your 90-day quote conversion rate at a glance. Track week-over-week revenue trends so you know if the pipeline is growing or tightening before it becomes a cash flow problem.
Never lose a repeat job. OneBookPlus surfaces customers due for their next service — annual maintenance, scheduled inspections, filter changes — so you can call before they call someone else.
Snap photos of receipts, log fuel, materials, and tool costs. See exactly how profitable each job really is after expenses.
See it in action
Not mockups — the real product screens for a working trades business. Drag-and-drop job pipeline, GST-compliant invoices with one-click payment, and quotes your client accepts in a single tap.
Every job visible at a glance, from quote to paid. Drag between lanes as the work progresses — the status updates, reminders fire, and invoices land automatically.

Line items, GST, ABN — all on a branded PDF. Stripe payment button for card, Open Banking for BECS. Clients tap, pay, done.

Quote ready on your phone before you leave the driveway. Client reviews on their phone, taps Accept, and it auto-converts to an invoice when work is done.

Simple Workflow
From quote to payment in four simple steps — designed around a typical tradie's day.
Send an itemised quote from your phone on-site. The customer gets a professional PDF with your ABN, logo, and terms.
Once accepted, the job goes into your calendar. Track time, log materials, and snap receipt photos as you go.
Convert the quote to a GST-compliant invoice with one tap. Send it before you leave the driveway.
Customers pay online via the invoice link. Automated reminders chase overdue payments so you don't have to.

About the author
Founder & CEO, OneBookPlus
Bishal has over a decade of experience in digital marketing, web development, and small business consulting across Australia. He has worked directly with dozens of Australian trade businesses — plumbers, electricians, builders, and landscapers — helping them streamline quoting, invoicing, and job management.
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.
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.
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.
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.
Join thousands of Australian tradies who invoice smarter with OneBookPlus. Free to start — upgrade when you're ready.

Whether you're a one-person operation or managing a crew, OneBookPlus adapts to how you work.
Running jobs solo, quoting from the van, invoicing between appointments. Needs fast mobile invoicing and automatic GST.
Managing 2-5 sparkies, scheduling jobs across suburbs, tracking who's where. Needs job scheduling and team coordination.
Multi-stage projects with progress claims, subcontractor management, and material costs. Needs detailed quoting and expense tracking.

Stop overpaying
Most small businesses stitch together 4-6 tools that don't talk to each other. Here's what that typically costs.
Real-world scenario
How a Melbourne plumber uses OneBookPlus on a typical Tuesday
Dave gets a booking request at 7am through his OneBookPlus booking page — a blocked drain in Brunswick. He confirms it with one tap from his phone and it drops into his calendar.
He arrives at 8:30, diagnoses the issue, and creates a quick quote on his phone: $380 labour + $45 materials, GST included automatically. The customer accepts the quote link on the spot.
Job done by 10am. Dave converts the quote to an invoice with one tap, sends it before he's back in the van. The customer pays online via the invoice link while Dave drives to his next job.
At the end of the day, Dave checks his dashboard: 3 jobs completed, $1,200 invoiced, one payment already received. His expenses (fuel receipt, parts from Bunnings) were logged with photos during the day. Come BAS time, his GST summary is already done.
