BillBook help
BillBook for accountants
If a client runs their billing through BillBook, here's exactly what you can pull out of it, on what basis it's prepared, and where its boundaries are — in the language you'd use, not marketing talk.
Profit & loss (monthly)
Insights → Profit & loss produces a monthly income statement: revenue is net of VAT, recognised on an issue-date (accrual) basis from issued tax invoices and sales invoices, with credit notes deducted. Drafts and voided documents are excluded. Expenses appear as recorded, grouped by category. Below the statement sit two cash figures: payments actually received in the month, and open receivables across all time. Every month exports to CSV.
VAT summary (output tax)
The VAT report (linked from Documents and Insights, available on every plan) lists each tax invoice, sales invoice and credit note for the month with net, VAT and gross — 14% computed per line at issue time, zero-rated and exempt lines carried at their own rates. Credit notes subtract. It's a filing prep aid on an issue-date basis, not an official return — totals drop into the GRA's Optimal portal, due the 21st. CSV export included.
Statements & receivables
Each customer has a statement of account (Starter plan and up): a chronological ledger of invoices, credit notes and payments with a running balance, plus an aging breakdown (current, 1–30, 31–60, 61–90, 90+ days) of what's still open. Statements print to PDF.
Document integrity
- Numbering is sequential per document type and can't be hand-edited on individual documents; prefixes are configurable.
- Issued documents are voided, never deleted — the numbering trail stays intact. Corrections go through credit notes.
- Receipts are generated from recorded payments (method, date, reference), so proof-of-payment ties back to the invoice it settles.
- Money is stored in integer cents — no floating-point drift in totals.
Getting the data out
Settings → "Your data" exports everything — documents, lines, customers, payments, expenses, stock, contracts — as one JSON file, any time, on any plan. The P&L and VAT reports export CSV directly. No lock-in, no request forms.
Where the boundaries are
Honest scope, so you know what you're working with: BillBook is a single-entry billing and records system, not a double-entry general ledger. It does not hold assets, liabilities or opening balances, so it does not produce a balance sheet — the P&L, cash figures and receivables are computed from documents, payments and expenses it actually holds. For most small clients that's exactly the raw material you need; the ledger stays yours.
