Sales signed a project on Monday. Finance heard about it on Thursday. The invoice went out the following Tuesday, and only if someone remembered. Retainers were missed. Refunds processed without reversing revenue. The founder spent month-end making decisions against numbers a fortnight stale, and the controller was the last one out every Thursday night.

The books move when the business does. Invoices, receipts and journal entries fire from real events, not month-end memory.

What is event-driven accounting?
Event-driven accounting writes the books from real operational events, projects signed, milestones shipped, refunds processed, deposits received, instead of from month-end memory. The engine emits the right artefact for each event: a deposit invoice, a draw-down, a journal entry, a bank match, so the books reconcile to within a day of operations.
We sit with your business. We find the operational problem costing you the most. We build the system that fixes it.
An event-driven accounting layer. Operational systems emit events, projects signed, milestones shipped, refunds processed, deposits received. The engine writes the right artefact: a deposit invoice, a milestone draw-down, a recurring charge, a journal entry, a bank match. Rules are config, not code. The firm can change VAT treatment or cost-centre splits without engineering work.
Books reconcile to within a day of operations. Month-end takes hours instead of weeks. Every entry traces back to the event that produced it. Auditors get answers in seconds. Revenue stops slipping through cracked spreadsheets.
One example, a 12-person consulting firm on UK VAT. Yours would mirror your chart of accounts, tax rules and project taxonomy.
Books that follow the work.
Fire an operational event on the left. The engine matches a rule, generates the right artefact, and posts the entry to the correct ledger.
Flip a toggle and re-fire the same event to see different entries land.

Book a discovery callAccounting that posts itself, audits itself, reports itself.
Every recurring accounting motion, deposit invoice, milestone draw-down, recurring charge, journal entry, bank match, fires from a real operational event, not a calendar reminder.
Explore AutomationEvery ledger entry carries the event ID and the rule that produced it. Auditors reconstruct the full chain of evidence for any line, any time.
Explore Audit TrailsNot the primary focus for this system.
Because the books reflect operations in near-real-time, AR ageing, MTD revenue and project margin are reportable any day of the month, not just at close.
Explore AnalyticsFrequently asked questions
- What does automated accounting actually automate?
- The gap between when something happens and when the books know about it. Operational systems emit events; the engine writes the invoice, the recurring charge, the journal entry, or the bank match, so revenue stops slipping through cracked spreadsheets and month-end takes hours, not weeks.
- Is it a replacement for our accounting software?
- It’s a bespoke event-driven layer shaped to how your business actually operates, lean, targeted, with the audit trails, permission roles, and workflows you genuinely need. Rules are configuration, so you can change VAT treatment or cost-centre splits without engineering work.
- How does it help at audit and month-end?
- Every entry traces back to the event that produced it, so auditors get answers in seconds and month-end stops running long. The controller is no longer the last one out every Thursday night, reconciling six spreadsheets by hand.
Systems we often build alongside this one.
- Internal Knowledge & SOP AssistantThe company playbook stops being a folder no one reads, it becomes the system that answers questions for the whole team.
- Legacy BridgeKeep the spreadsheet, the green-screen ERP, and the bespoke tool that still does its job, and connect them to a modern AI workflow without rewriting any of them.
- Inventory Clarity SystemEvery pallet, every linen, every tool, counted by the building itself. Stock, books, and orders stop disagreeing.
- Client Onboarding SystemTwo checklists, one workflow. The client moves through their part; the firm's part runs itself in lockstep, no email chase, no client left in limbo.
