Bookkeeping without the accountant
Bookkeeping is the part of running a small business that nobody started a business to do: logging every invoice, filing every receipt, working out how much GST you've collected versus paid, and making sure the numbers line up when the BAS deadline arrives. Most sole traders either let it pile up into a shoebox-and-spreadsheet panic each quarter, or pay a bookkeeper to untangle it after the fact — which is the most expensive way to keep records.
A good bookkeeping app removes the panic by keeping the books current as you work. When you send an invoice, the GST is already calculated. When you log an expense, it's already categorised and counted against the GST you can claim. By the time BAS is due, the quarterly summary is a review — not a reconstruction. That's the difference between bookkeeping software and a spreadsheet: the spreadsheet stores numbers, the software keeps them straight.
OneBookPlus handles the Australian-specific parts natively — automatic 10% GST on every invoice and quote, ABN-validated tax invoices, AUD formatting, and a BAS-ready summary that rolls up GST collected, GST paid, and net GST payable. Try the maths first with the free GST calculator and BAS calculator, or estimate what you currently spend with the bookkeeping cost calculator.
The bookkeeping lives inside the broader OneBookPlus Finance module, so your invoices, expenses, and GST position all share one database — no CSV exports, no copy-pasting between an invoicing tool and an accounting tool. A paid invoice updates your GST position and your customer record at the same time.

Real-world scenario
A real bookkeeping flow for a sole-trader electrician
Monday: Priya finishes a switchboard upgrade and raises the invoice from her phone on the way back to the ute. OneBookPlus adds the 10% GST automatically and stamps her ABN on the tax invoice. The customer pays by card from the link two days later — that payment quietly lifts her GST-collected total for the quarter and updates the customer's record in the same moment.
Across the week she snaps photos of receipts — cable from the wholesaler, fuel, a new multimeter — and logs each as an expense. Each one is categorised and counted against the GST she can claim back, so her GST-paid total builds as she goes instead of being reconstructed from a glovebox of receipts in July.
End of quarter: there's no shoebox session. The Finance module already has GST collected, GST paid, and net GST payable rolled up into a BAS-ready summary. Priya checks the figures against the free BAS calculator, hands a clean set to her BAS agent — or lodges herself — and gets back to the tools. The bookkeeping happened while she worked, not in a panic the night before the deadline.

FAQ
The best fit depends on how you actually run your business. If you invoice customers, track expenses, and need BAS-ready GST totals — but don't want to pay for and learn full accounting software — OneBookPlus covers the bookkeeping basics with native 10% GST, ABN-validated tax invoices, and quarterly BAS summaries. It's built in Melbourne for the Australian market, so GST, AUD, and ATO record-keeping are there from day one rather than retrofitted.
Most sole traders and small businesses use bookkeeping software to keep their day-to-day records straight — invoices, expenses, and GST — and bring in an accountant or BAS agent only at tax or quarter time. OneBookPlus keeps your numbers BAS-ready throughout the quarter so the handover (or the self-lodge) is a review, not a rebuild. It doesn't replace registered tax advice, but it removes the shoebox-of-receipts problem that makes accountant time expensive.
Yes. Every invoice and quote applies 10% GST automatically (inclusive or exclusive pricing supported), and the Finance module rolls up GST collected, GST paid, and net GST payable into a BAS-ready summary each quarter. You can also pre-check the maths with the free BAS calculator and GST calculator before you sign up.
Standalone bookkeeping and accounting tools in Australia typically run $15–$70 per month, and many small businesses bolt on a separate invoicing or booking tool on top. OneBookPlus includes invoicing, expense tracking, GST, and BAS summaries in every plan — including a Free tier — so bookkeeping isn't a separate subscription. The bookkeeping cost calculator estimates what you'd otherwise pay a bookkeeper or for a tool stack.
Yes. Many OneBookPlus users come from spreadsheets, a shoebox of receipts, or a single-purpose invoicing tool. Because invoicing, expenses, contacts, and BAS reporting share one database, you stop copy-pasting between tools — a paid invoice updates your GST position and your customer record at the same time.
OneBookPlus covers the bookkeeping that most small businesses actually need — invoicing, expenses, GST, and BAS-ready summaries — alongside bookings, CRM, and marketing in one app. It's deliberately lighter than a full general-ledger accounting suite.
