About Seikyu

Make a clean, professional invoice in one minute -- no account, no subscription, no cloud.

Invoice Maker is the invoicing app the way it should be: you buy it once, it works forever, and your business data never leaves your phone. Create quotes, invoices and receipts, share them as beautiful PDFs, and get back to work.

WHY PEOPLE SWITCH TO INVOICE MAKER
- One-time purchase -- no monthly fees, ever
- Completely offline -- works on a plane, at a job site, anywhere
- No signup, no tracking, no data collection. Your clients stay yours

CREATE IN SECONDS
- Quotes, invoices and receipts with automatic numbering
- Reusable clients and items -- tap to add
- Quantity, unit price, per-line tax rates and automatic totals
- Discounts, notes and payment details

BUILT FOR YOUR COUNTRY
- Your currency, your number format -- automatically from your device
- Freely configurable tax rates (VAT, GST, sales tax...)
- Japan mode: fully compatible with the qualified invoice system (???????) -- registration number and per-rate tax breakdown

SHARE AS PDF
- Crisp, professional PDF layouts
- Send by email, message or any app straight from the share sheet
- Mark documents as sent or paid, and track what's outstanding

Note: in countries where structured e-invoicing is mandatory for B2B (e.g. CFDI, NF-e, FatturaPA), use Invoice Maker for quotes, receipts and records.

Your invoices, your data, your phone. That's it.
