About this app

Quoice is the simplest way for a sole trader to send a professional quote, invoice and receipt — right from your phone, even with no signal. Built for self-employed tradespeople running a one-person business: plumbers, electricians, handymen, builders, landscapers, gardeners, cleaners, painters, mechanics — any small business that quotes a job and bills for it.

One payment, yours for life
Quoice is a single one-time purchase — no subscription, no renewals, no account to create. Try every feature free for 7 days (the trial only starts when you save your first document), then one small payment unlocks it forever. And whether you buy or not, your documents always stay viewable and shareable — your records are yours to keep.

Quote, invoice and get paid — the way a solo trader actually works
• Build a quote or estimate in under two minutes, from your saved price book or typed on the spot
• One tap turns an accepted quote into an invoice
• One tap records a payment and creates a numbered receipt
• Deposits and part-payments handled properly — deposit receipts show the balance remaining
• Clean, professional PDF invoices — many designs to choose from — shared straight to WhatsApp, email, or anywhere your phone can send
• Works 100% offline. No signal on site? The quote still gets made, and Quick Share hands it to your customer on the spot
• Overdue invoices surface on their own; an Unpaid filter shows exactly who still owes you

Books your accountant will thank you for
Sequential invoice numbers, void instead of delete, and receipts that are never renumbered — the clean paper trail the taxman likes to see. Choose your own invoice numbering format — plain (INV-0001), by year (2026-0001) or number-first (046/2026) — so it matches what your country expects.

Works in your language, and your country's rules
Full app and documents in English, Spanish, French, German, Italian, Dutch, Polish and Portuguese. Invoices follow local conventions — the right tax-number label (VAT, USt-IdNr., NIF/CIF, N° TVA), an optional date-of-supply line where required, and each country's own date and currency formatting.

Ready for tax time
Export your invoices and payments to a spreadsheet your accountant can open in Excel or Google Sheets — one tap, and it's yours to keep.

Your data stays yours
Everything lives on your phone — no cloud, no account, nothing collected. Back up your whole business (price book, customers, every quote, invoice and receipt) into one small file you keep, and restore it on any phone whenever you need.

Quoice does one thing, and does it well: the paperwork side of a one-person trade business — quoting, invoicing and receipts. One honest payment, for a tool that respects your work.
