Product
Brass is not Xero. It does not do payroll, VAT returns, stock, or five-user practices. It keeps a sole trader's books, nags you on the four dates, and hands over a pack.

Record
Add income when you get paid. Snap a receipt onto the line. Log mileage at HMRC simplified rates. Brass tries to fill the date, amount and shop from a photo, then you check it. Categories match what HMRC asks for on a quarterly update.
Remind
Before 5 July, 5 October, 5 January and 5 April you get a running total and a list of what is still missing. That is the product, as much as the ledger.
Export
PDF summary and CSV of every line, or a read-only link they open without an account. Email it. We are not asking them to learn another login.
Categories
You pick from the headings a sole trader already sees on a quarterly update. You are not inventing your own system and translating it later.
Turnover
Other business income
Cost of goods
Vehicle, fuel and travel
Property, utilities, insurance
Repairs and maintenance
Phone, office, stationery

Accountancy and legal
Other allowable expenses
This is a record-keeping layout, not tax advice. If you are unsure what is allowable, ask your accountant.
The reminder
A few days before each date: running income, running expenses, anything still blank, and a button to export. No weekly digest. No marketing drip.
