A cash book (day book) records money in and money out as it happens. Wave and QuickBooks are full accounting products: double-entry ledgers, bank feeds, invoicing, tax reports. Ours records receipts and payments, keeps a running balance and builds a period summary and a CSV export, from chat, with no account and no network. The facts below are read from each vendor's own pricing and product material.

Pick them when you need real bookkeeping: a chart of accounts, bank reconciliation, and financial statements you or an accountant can rely on. Wave's core accounting is free with paid add-ons for payments and payroll. QuickBooks is the broader product with payroll, inventory and accountant tooling from roughly $35/mo. Neither is a cash book, and using one as just a cash book means paying for or maintaining much more than you use.
Pick ours when what you want is a day book: log money in and money out in chat, keep a running balance, pull a period summary and export CSV, with no account and no network call. It is free to record and export, and Pro is a $19 once unlock for Markdown and the period summary. It does not replace double-entry accounting; if you need statements an accountant can file from, use Wave or QuickBooks instead.
