InvoiceKoi

Android invoicing for tradespeople: reuse clients and rates, turn estimates into invoices, and track deposits, time and expenses, with core drafting offline. Drafting is free; issuing new numbered documents requires a subscription (US $9.99/week or $99.99/year, local Google Play pricing varies), while AI, backup, purchase verification and payment collection need internet.
