Invoice Builder
A private invoice ledger in one HTML file on your machine (draft, sent, paid): no account, no subscription.
This is not a screenshot. It's the real tool, running right here: go on, put something in it.
Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.
The work was finished weeks ago; the getting-paid part is still 'in progress'. Invoice Builder keeps each invoice as a plain honest row — client and description, amount, whether it's draft, sent, or paid, and when it's due. The awkward question of who still owes you what answers itself at a glance.

- No account. No login, no sign-up, no e-mail wall.

- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Whatever you put in (Client / description, Amount, Status and Due) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of invoice builder entries is a decade of your own handwriting, kept in a document you can back up like any other.
If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.
Getting your data out
Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.
Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.
Questions people ask
How does Invoice Builder track whether I've been paid?
Every invoice carries a status — draft, sent, or paid — along with the client, the amount, and the due date. Sort by status and the unpaid ones line up and look at you.
Is Invoice Builder enough for a small freelance business?
If your invoicing needs are 'who, how much, sent or paid, and by when', yes. It's built for the freelancer with a dozen clients, not the firm with a billing department.
Are my invoices and client details kept private?
Completely. The tool is one HTML file running offline in your browser — no account, no cloud, no third party reading your amounts. Everything stays on the page, and the file is yours for good.
