AutoLedger is a guided walkthrough for UK accounting practices: one fictional client (Hazelbrook Coffee Roasters Ltd), one month, and a play button. The bank feed lands, every transaction is categorised with its VAT treatment, the ledger reconciles, the nine-box MTD VAT return fills itself in and goes to HMRC, and the reports draw themselves — while an activity log narrates what the engine is doing and why. Nothing leaves the browser; the client, the bank and the filing are all simulated.
