Billzy: Bills & Invoices Maker

Billzy turns your phone into a billing desk. Create invoices, estimates, and receipts wherever you are — on a job site, behind a counter, in a van with no signal — and share them as clean PDFs through WhatsApp, Mail, or Messages.

No account. No sign-up. Your clients, catalog, and documents live on this device.

INVOICES THAT LOOK ESTABLISHED
Pick a client, add lines from your catalog, preview the PDF, share. Twelve layouts — Classic, Modern, Minimal, Bold, Trades, Elegant, Studio, Corporate, Ledger, Boutique, Executive, and Devanagari — with your logo, accent colour, font pair, and signature.

ESTIMATES THAT BECOME INVOICES
Send a quote with a valid-until date. When the client says yes, mark it accepted and convert it — all the lines or only the ones they approved.

RECEIPTS ON THE SPOT
Money already changed hands? Issue a receipt and hand it over. No balance to chase.

KNOW WHAT YOU ARE OWED
One Outstanding card on Home shows overdue and billed-this-month at a glance. Attention rows surface overdue invoices, accepted estimates you have not billed, and estimates about to expire.

PAYMENTS, INCLUDING THE MESSY ONES
Record full or partial payments. Handle a shortfall by leaving it owed, writing it off, or rounding it away. Handle an overpayment as client credit, a refund, or a tip. Add an early-payment or goodwill discount. Log a cheque number or UTR as a reference.

FOLLOW-UPS WITHOUT THE AWKWARDNESS
Billzy reminds you on your own phone — 3 days before due, on the due date, 3, 7, or 14 days overdue. Tap the reminder and pick a tone: Friendly, Professional, or Firm. Edit the draft, then send it by WhatsApp, SMS, or email. Mute clients who always pay eventually, and skip balances under 500.

A CATALOG YOU BUILD ONCE
Save services, hours, days, pieces, or square feet with prices, tax rates, and photos. Import with CSV. Raise or round many prices at once with Bulk price.

CLIENTS IN ONE PLACE
Import from your contacts, merge duplicates, and see each client's outstanding balance and full history.

RECURRING INVOICES
Set a rule — weekly, monthly, or every N days — and Billzy drafts the next invoice for you to review and send.

REPORTS WHEN YOU NEED THEM
Month, quarter, financial year, or a custom range. Paid versus outstanding, win rate, pipeline, aging buckets, top clients, top items, and tax collected by rate. Export any report as a PDF.

BUILT FOR HOW YOU ACTUALLY WORK
- Multiple businesses, each with its own clients, catalog, numbering, and reminders
- Your country's currency, tax label, and date format
- Invoice numbering you control: prefix, year, separator, counter width
- Inclusive or exclusive tax, tax before or after discount
- Payment instructions and QR that print on the PDF
- Document labels in several languages
- Light, dark, or system appearance

PRIVACY, PLAINLY
Billzy has no cloud and no account, so there is nothing to leak. Your ledger stays on the device. Reminders are local notifications. A follow-up message never leaves your phone
