Flat-fee bookkeeping for the Xero file you already use.
We work inside your existing Xero file — nothing migrates, nothing to relearn, no parallel ledger to keep in sync. Three flat monthly tiers, a clean close every month, and the same reviewer on your account answering the next question.

Xero pricing
Three flat tiers, picked around your Xero file.
The number is set in writing before any work begins, and it does not creep up because reconciliation took longer than usual. You see the price, you see the included scope, and we answer any pre-signing question in writing.

What we do each month
Four steps, run inside your Xero file.
Every Xero cycle runs the same way. The steps are repeatable; that is what keeps your retainer flat and your close predictable — the same way every month, inside your existing Xero file.
Same day each month
Categorize
Every transaction coded against your Xero chart of accounts
AI proposes a match from your real history; anything ambiguous is held for a manual review — never guessed, never posted silently.
Reconcile
Bank, card, and payment feeds reconciled inside Xero
Cleared transactions matched against the ledger; duplicates, omissions, and suspicious merchants flagged with a plain-English note attached to the entry.
Close
Books are closed on the same day each cycle
Variance report written for the reader who has to defend the numbers — your CPA, a lender, a buyer. One-page summary emailed when it’s done.
Review
Anomaly review runs every cycle, not just at year-end
New payees, sudden swings, and missing recurring items surface as flagged Xero entries with the why — not a 60-page report you never open.
No-migration promise
Your Xero file is the source of truth. We connect in.
Nothing to migrate.
We connect into the Xero file you already run, as a firm user. No data export/import, no parallel ledger to reconcile against, no chart-of-accounts rewrite — your Xero file stays the source of truth.
Nothing to relearn.
Your team keeps the workflow it knows. The monthly review call lives inside Xero, and the reviewer is the same person who closed your last cycle. A new Xero account owner ramps in days, not weeks.
Nothing to second-guess.
If we ever part ways, the file — chart of accounts, transaction history, attachments, saved reports — leaves with you, unaltered. There is no platform lock-in because we never moved you off yours.
Xero FAQ
Three Xero questions, answered plainly.
The questions Xero owners actually ask before they sign — pricing, support inside the file, and what stays in Xero if the engagement ends. If yours isn’t here, write to us; replies come from a person, not a queue.
