Move the client book.Without the cliff edge.
AccountsOS is built for the whole practice, whether that means 20 clients or 500. Move in controlled batches, keep Xero running while you verify the work, and let Finn take on more of the book as your team becomes comfortable.
Pilot one client, then migrate the whole book.
The migration path is deliberately low-risk
You do not need to move every client, retrain the team and change every process in one go. Prove it on one client, then scale.
Pilot one client
Start with one straightforward client or a small batch. Check how Finn reads the export, maps the data and runs the workflow before committing the wider book.
Review the import plan
Finn reads Xero exports, statements, contacts, opening balances, invoices, bills and VAT history, then shows the mapping before anything posts.
Scale the migration
Once the pilot works, migrate the rest in batches: 50, 100 or 500+ clients, with the practice staying in control of review and rollout.
The reason to switch is bigger than price
Xero cost is the obvious pain. The deeper opportunity is that AI-native accounting changes the economics of serving each client: less manual chasing, fewer repetitive reviews, faster answers, and a client experience that no longer feels pre-AI.
Xero has announced two changes that hit practices running many client organisations hardest: subscription prices rise again from 1 September 2026, and from the same date the multi-organisation discount is removed, so every client org on the practice's books goes back to paying full price. AccountsOS stays flat: £12 per live client a month, no minimum.
Reduce the software tax per client
A per-client stack gets painful as the book grows. AccountsOS practice pricing is built around live clients, volume discounts and one bill to the practice.
Cut the admin time, not just the licence cost
Finn categorises, reconciles, reads documents, flags gaps and prepares month-end, so staff review exceptions instead of touching every line.
Modernise without losing control
Use AccountsOS internally, invite selected clients, or explore API/MCP/own-brand workflows. The practice keeps the relationship and chooses the client experience.
Pilot structure
Start with a batch you can judge
- Pick one simple client and one messier client.
- Compare opening balances, documents, VAT history and reports.
- Let staff test Finn before the whole team changes workflow.
- Move more clients only once the practice is comfortable.
