THIS WEEK RECONCILED
When the ledger lives inside Claude
In a recent LinkedIn thread on how accountants use Claude, one accountant described Claude building an entire balance sheet reconciliation of about 2,000 transactions covering nine months. That's a headline result. For a UK practice, the useful question is where it fits.
It doesn't fit your live, VAT-registered clients on Xero. Keep those exactly where they are.
It earns its place on the quiet jobs, such as the dormant company, the small landlord or the once-a-year cleanup, where paying for a software subscription always felt like overkill. For those, Claude can now do the bookkeeping in a single sitting.
At Xero's list price, even the Ignite plan now costs £18 a month excluding VAT. That's £216 a year for a client who needs one set of accounts.
This week we cover which jobs suit a Claude ledger, which don't, and how to keep the books somewhere you can pick them up again next year.
RECONCILED ROUNDUP
Worth knowing this week
Claude ledger experiments are spreading
One tester gave Claude a month of QuickBooks and told it to propose changes rather than post them. It got 26 of 26 checks right, twice, and refused to call the month reconciled without the bank statements. Why it matters. The results worth copying come from low-volume annual jobs. Live clients still belong in your bookkeeping software.
Beancount as the storage layer
Open-source projects such as CFO Stack pair Claude with Beancount, a plain-text ledger, and Beancount now publishes its own guide to using AI with your ledger. Why it matters. The ledger file keeps the books between sessions, so next year you pick up where you left off.
CLAUDE AS A LEDGER RECONCILED
Best for the annual job, not the live client
Use it for dormant companies, single-property landlords and annual cleanups where a live subscription was never justified. For everything else, stay on Xero.
How to run it
Point Claude at the bank data. Give it the statements or a CSV, and it categorises each transaction into a UK chart of accounts.
Save the ledger in Beancount. It's a plain-text file that stores the books, so next year you reopen it and roll it forward instead of starting again.
Build the outputs as a Claude artifact. You get the trial balance, balance sheet and P&L on screen, ready to check.
Compliance first. Keep client data on a Team or Enterprise plan, and check the client is out of MTD scope before keeping their books outside Xero or QuickBooks. Records still have to be accurate and kept for the required period, whichever tool holds them.
Rich's Take
"Nobody's cancelling Xero for live clients yet. But spinning up a brand-new subscription for a once-a-year job just got a lot harder to justify."
YOUR QUESTIONS RECONCILED
"Can I really keep a client's books outside Xero or QuickBooks?"
For the right client, yes. The rules require records that are accurate, complete and kept for the required period. They don't specify which software holds them.
What you have to be careful with is MTD. If the client is mandated for Making Tax Digital, they need compliant digital records and quarterly filing, which a hand-built ledger won't provide. For jobs outside MTD, such as dormant companies and some landlords, a saved ledger can work well. Check scope first, note the approach in your file, and keep the work on a business plan.
PROMPTS RECONCILED
This week's prompt
Give Claude the bank data and this instruction. Try it on a copy or a low-stakes file first, and check the result before you rely on it.
"Categorise these bank transactions into a UK chart of accounts and produce a trial balance, balance sheet and P&L. Persist the ledger in Beancount so we can reopen it next year. Flag anything you're unsure of rather than guessing."
