Capture
Send invoices and quotes, log expenses, snap a photo of a receipt. Every time you do, your books update.
Built for solo entrepreneurs
Your books, done as you go.
1code Books keeps your company's finances in order all year — invoices, expenses, receipts — so when filing time comes, the hard part is already done.
An AI-native accounting platform for UK small businesses. You run your business; your AI bookkeeper keeps up.

Most small businesses dread year-end.
It doesn't have to be that way.
If you run a small company, you know the drill: a shoebox of receipts, a year of bank statements, and a scramble to make sense of it all before a deadline. The tools out there were built for accountants, then had "AI" bolted on as an afterthought.
We took the opposite approach. 1code Books is built AI-native from the ground up — so the work happens quietly all year, not in a panic at the end.
Capture as you go.
We'll handle the rest.
Understand
Your AI bookkeeper reads, sorts and reconciles everything in the background — and flags anything that looks off, so small mistakes don't become big ones.
File with confidence
By year-end, your accounts and tax figures are already prepared. You review, you approve, you file. You stay in control of every number.
Everything a small business needs in one place
Invoicing & quotations
Create and send professional invoices and quotes in seconds. Track what's paid, what's outstanding, and what's overdue.
Customers (CRM)
Keep every customer in one place — contact details, history, and the documents tied to them.
Expenses & receipts
Log expenses and capture receipts on the go. Mobile receipt capture coming with our app.
Reconciliation
Match your transactions automatically, so your books always reflect reality.
Year-end, made simple In development
The system gathers everything needed for your statutory accounts and Corporation Tax return as you trade — so filing becomes a review-and-approve step, not a project. Filing capability is in active development.
Your AI bookkeeping buddy
Not a chatbot bolted on — an assistant built into the core, that understands your business and helps you make sense of your numbers in plain language.
Secured by you, not by a password
Passwords get phished, reused and stolen — they're the weak link in most online tools. 1code Books is being built to work without them. You'll sign in with fingerprint and Face ID through our mobile app, so access to your financial data is tied to you, not to a password someone could trick out of you.
Passwordless, biometric sign-in — designed to resist phishing and account takeover.
Made for the people doing it themselves
1code Books is built first for solo founders and small business owners who run their own books — the people who'd rather spend time on their business than on paperwork.
And if you'd rather hand it off? Accountants and formation agents can use 1code Books to manage filings for the businesses they support — so whether you do it yourself or get help, the work is already in good shape.
1code Books helps you prepare and understand your figures and reduces the room for error — but you always review and approve before anything is submitted. Your business, your numbers, your decision.
