## What is Solo Invoice?

There is no cap on line items.
Nothing stops at 26 rows, and nothing gets cut off on page two.
Quote, delivery note, invoice and receipt are all rebuilt from the same rows in a single tap.

Solo Invoice is a billing app for one-person businesses — freelancers, sole traders and side-hustlers who issue their own paperwork. No account, no cloud. What you type stays on your device.

DON'T RUN OUT OF ROWS
- Unlimited line items; A4 pages are added automatically as you go
- The date field is free text: leave it blank, or write "7/1-7/15"
- Add units such as "hrs", "pcs", "days"
- Insert heading-only rows to group work into sections
- Drag to reorder

FOUR DOCUMENTS, ONE SET OF DATA
- Invoice / Quotation / Delivery note / Receipt
- Turn a quote into an invoice, or an invoice into a receipt, in one tap
- Receipts support a "for ..." description line

BUILT FOR JAPAN'S QUALIFIED INVOICE SYSTEM
- Prints your registration number
- Per-row 10% / 8% (reduced) / non-taxable rates, summarised per rate
- Tax exclusive, tax inclusive, or no tax column
- You choose rounding: down, up, or half-up
- Optional 10.21% withholding, with the net payable amount

ENTER IT ONCE
- Trading name, address, phone, fax, email, registration number
- Bank details for transfers

SEE IT BEFORE YOU SEND IT
- Review every page of the PDF inside the app before sharing
- Files are named so you can find them later
- Share via mail, messaging, AirDrop, Files or AirPrint

NO ADS
- No ad SDK. No banner covering your buttons
- A single "Picks" tab links to the official Japanese tax-office pages you actually need — registration-number lookup, filing, and reference material — plus the other apps made by the same developer. Both are hand-picked fixed lists, not served ads
- No in-app purchases either

PRICING
- A one-time purchase. Nothing more to pay after that
- No in-app purchases. Not a subscription
- Every feature is available from the start, with no caps on documents or line items

### 5/5 — 1人に仕事してる人には便利

*2026-08-26*

個人で仕事をしているので、請求書を作るためだけに大げさな会計ソフトを使うのがちょっと面倒でした。

これは見積書・納品書・請求書・領収書を同じ明細から作れるので、とにかく楽。インボイスにも対応しているし、PDFにしてそのまま送れるので、請求書を作って送るまでがかなりスムーズになりました。

しかも買い切り120円で、サブスクも広告もなし。こういう「必要なときだけ使いたい」アプリはこれくらいシンプルなのが一番ありがたいです。

一人で仕事している人なら、とりあえず入れておいていいと思います。
