UK bookkeeping SaaS with confirm-before-save, BYO-key AI Copilot (pre-revenue)
Ask your books a question in plain English: the AI Copilot drafts the entry and saves nothing until you confirm, and it runs on each business's own AI key, so AI usage costs never land on the owner. Honest status: LedgersMind is a pre-revenue, unpublished web app with no users and no revenue. It has been run only in a development environment with Stripe in test mode. This is an asset sale of working source code, documentation and acquisition materials, not an operating business. What it is: a web app for UK small-business bookkeeping, covering sales and purchase invoices, a double-entry ledger, VAT and reports, payroll and multi-business pages, plus subscription billing and an AI Copilot. Plans in the app are Starter £9.99, Pro £24.99 and Business £59.99 a month. Strengths: Stripe subscription checkout works end to end in test mode. A purchase persists after refresh and re-login, and an upgrade prorates the existing subscription instead of creating a second one. TypeScript typecheck passes, 52 checkout/auth tests pass, and the full suite passes 291 of 293 tests (2 stale tests are disclosed). AI Copilot: each business brings its own OpenAI key, stored encrypted per tenant. It needs a paid plan and has a monthly message cap. Drafts are saved only on Confirm. Includes an acquisition data room and buyer decks. Included: full source code, docs and a written handover note. Not included: customers, revenue, a live URL or any third-party accounts or keys. Known gaps: never deployed; Stripe test prices need setting up to match the app; HMRC/Making Tax Digital code is not qualified and is production-locked; Open Banking is sandbox-only; no security audit. Serious enquiries welcome. I will answer any question about the code, tests, billing set-up and known gaps before you commit, and I recommend closing through Escrow.com.
