Built for actual site use
- Big buttons — usable with gloves, dirty hands, fat fingers
- High contrast dark mode — readable in sun, in a basement, at six in the morning
- Works offline — no signal in a basement? Still works.
- Mobile-first — designed for one-thumb use on a phone
- Print-ready invoices — generate a clean PDF, send via email/WhatsApp/text
Built for actual trades
- CIS handling both directions — receiving (subcontractor) and paying (contractor). Most apps cock this up.
- Simplified vehicle expenses — 45p first 10k miles, 25p after, baked in
- UK 2025/26 tax engine — personal allowance, basic/higher/additional bands, PA taper, NI Class 4 (used as 2026/27 proxy)
- VAT settings — standard rate, flat rate scheme (9.5% labour-only or 14.5% general construction)
- "Set aside £X per month" — divides estimated tax bill by months remaining until Jan 31

That's it. No account, no email, no card.

Sovereignty — what this actually means
Every other accounting app stores your data on their server. You pay a monthly fee. If you stop paying, you lose access. If they get hacked, your receipts get leaked. If they get bought by a bigger company, the terms change overnight.
FallAccount Trades stores everything on your phone — IndexedDB and localStorage. We have no server. We cannot see your data. We cannot lose your data. We cannot sell your data. There is no "we" — the file is yours.
- ✅ Works offline indefinitely
- ✅ Survives our company dying / disappearing
- ✅ Survives the internet going down
- ✅ Survives any platform shutting us down
- ✅ Backup via JSON export — keep on USB or email to yourself
- ✅ Restore by importing the JSON — your phone restored exactly
The trade-off: if your phone dies and you didn't back up, the data goes with it. Same as a paper notebook in your van getting wet. Back up monthly. There's a button for it.
For trades-mates: forking your own
Got mates who'd want one? Three options:
Option 1 — free favour
Help your mate make their own copy. Five minutes of clicking. They get their own version with their brand name on it. You earn a beer.
Option 2 — set it up for them (TBA–TBA cash)
- Fork this repo to a new repo with their name (e.g.
dave-plastering/my-accounts)
- Drop their logo / brand in via Settings
- Enable GitHub Pages on their repo
- Send them the link to bookmark
- Hand them a printed copy of the intro doc
- An hour's work · cash in hand · they get a tool they'd otherwise pay TBAnth forever
Option 3 — refer them
Send them to whoever made yours. They'll get one set up. You earn a credit.
