From the signed contract to the sent invoice, without leaving your device.

No. It has no timestamping, no history of corrections and deletions, and none of the search requirements, so neither the records inside the app nor the files it exports can be treated as compliant storage under the Electronic Books Preservation Act (電子帳簿保存法, usually shortened to 電帳法). Keep your statutory records by some other method that does meet the requirements. We would rather say this now than have you find it out during a tax audit.

No. We do not give tax or legal advice. Whether withholding applies, how to treat money you have fronted on a client's behalf, how Japan's consumption tax (消費税) or the Qualified Invoice System (インボイス制度) applies to you — these are judgements we cannot make for you. Please ask a licensed tax accountant or lawyer. This app is a tool that calculates what you have decided and puts it into the shape of a document.

Yes. From Settings you can export everything — contracts, work logs, business details — as a single JSON file, and restore from that same file. We will not hold your records hostage when you decide to stop. More precisely, we never had them, so there is nothing to lock you in with.

This introduction page reads in seven languages, but the app itself and the documents it exports are in Japanese and English only. The five languages other than Japanese and English are a translation beta and have not been through review yet. Finding this out after you are already inside is the worst way to find it out, so we are saying it here.

You do not need an account. Open it in a browser and it works. Since we hold none of your data, there is nothing for an account to be attached to. As for money: right now every feature, exporting the documents included, is free. We have not yet started selling the paid plan (Pro) to the general public. When we do, we will say so on this page. The only time we ask for your name and email address is when you subscribe to the paid plan.

They stay on your device. Importing uses read-only permissions — read events, and read the list of calendars — so the app cannot alter anything already in your calendar. Only if you use the feature that publishes your hours to a calendar do we ask for one more permission, and that one reaches nothing but the dedicated calendar this app creates. It cannot touch the events that were already there.

Yes. On work that needs no quote — hourly billing, say — leave the quote fields empty. Registering a contract, logging your hours and producing the invoice and the timesheet at the end of the month all work without one, and nothing on screen nags you to fill them in. The quotation itself is the one document you cannot produce, because a quotation with no basis for its figures is not a document at all; press the button and the app tells you what to fill in to make it possible.

Yes. Register the xlsx you were sent and point each field at the cell it belongs in. The app writes in the values while leaving the formatting, merged cells, row heights and shapes exactly as they were, so what your client receives looks like their usual form, filled in. There are places it cannot write. Cells holding a formula — a total, typically — are off limits, and so is any cell of a merged range except its top-left. The app inspects the form when you register it and tells you there and then if it cannot be filled, rather than quietly breaking the layout.

Because the length of a meeting and the time you actually worked are two different things. If an event is imported as an interval of work, then logging your real hours around it counts the same time twice. Imported events are attached to the day as a record of the day, and you decide how many hours to log as work. Without that separation, you end up invoicing for less than you did.
