Accounting software that can prove its own numbers

Go CashBook is Australian online accounting built on an append-only ledger, a real BAS/GST engine, and nightly self-auditing — so the numbers you lodge are numbers you can defend.

Why Go CashBook

A ledger that cannot lie

Every transaction is an append-only, dated event. Posted entries are never edited in place — corrections are reversals, so your history is complete and every balance can be traced back to the events that made it.

A real BAS & GST engine

Cash and accrual BAS from a purpose-built three-layer GST engine — not a naive tax-column sum. Blocking diagnostics stop a lodgement while anything is unresolved, and every line carries its reasoning.

Books that audit themselves

Every night, more than 60 integrity checks reconcile your general ledger against the underlying events — AR and AP control accounts, GST control, snapshot drift, trial balance. Problems surface before your accountant finds them.

Banking that keeps up

Import statements, match to invoices and bills, split with merchant fees, handle overpayments and refunds — with duplicate protection and friendly guardrails at every step.

Invoicing your clients notice

Branded invoices and quotes, repeating invoices, polished PDFs, payment reminders on a schedule you control, and customer statements that tie to the ledger to the cent.

Built for Australian rules

GST, BAS, ABN validation, Australian financial years and Sydney business dates are the core of the product — not a localisation afterthought.

Who it is for

Self-employed

Start with your own books: bank in, coded, BAS out. No accounting degree required.

Small business

Invoices, bills, inventory basics and fixed assets — with a ledger your accountant will actually trust.

Accounting practices

Client access, practice defaults, financial-statement packs and working papers that read straight from events.
