The ledger’s agents close the books.
We prove they balance.
Intuit converts the Desktop file for free and its agents categorize inside QuickBooks. BookSyncHQ is the independent layer above them for the two moments you are personally liable — moving a client between ledgers, and closing the books each month. Cent-exact against the bank and the source books. Every action logged, reviewable, reversible, exportable as a workpaper.Their agents post. We are the independent check, for the two moments you are personally liable: migration, and the monthly close.
Method. Every figure is compared in integer cents across both systems — no rounding, no sampling. Breaks are itemized, remediated line by line with your approval, and re-tied until the difference is zero. Processed transiently under commercial API terms; stored encrypted; deleted on your schedule.
Two moments you personally sign for. Both of them are arithmetic.
Moment one · you move the booksYou move a client from one ledger to another, and sign that nothing was lost.
- Trial balance, A/R aging, A/P aging and bank balances pulled from both systems and compared in integer cents. Exact equality only — a two-cent break is a finding, not a rounding error.Δ
- Every break itemized in your own vocabulary: undeposited funds, sales orders, inventory assemblies, units of measure, custom fields past the destination’s limit, multi-currency history.Δ
- Remediation you approve line by line, then a 30-day parallel run that opens an exception the night any account diverges — with the earliest divergent transaction named.Δ
- An evidence-backed Migration Certificate for the client file. $149 per entity, one-time; ten-pack $1,190.§
Moment two · you close the monthYou close the books, put your name on them, and hand them to someone who will rely on them.
- Bank-statement tie-out against the ledger register, in integer cents, run daily in the background rather than monthly in a panic.Δ
- Deterministic first: the matching is arithmetic, and an agent only ever sees the residual that arithmetic could not clear.Δ
- A materiality-ranked exception queue — approve, edit, reject, teach — so month-end becomes review-and-sign.Δ
- $12 per connected client per month, $60 floor. 10 runs per client included; $1.50 per run beyond.§
The ledger’s agent asserts. We check it against something it does not control.
Categorizes the bank feed inside QuickBooks and marks the month closed.
Re-derives the register from the bank statement and ties it to the ledger in integer cents. Δ 0.00 or it isn’t closed.
Converts the QuickBooks Desktop company file to Online.
Intuit converts Desktop files for free. We sell the verification — trial balance, A/R, A/P and bank balances diffed across both systems, with the breaks named.
Reports success. The detail of what it did lives inside its own product.
Every check, exception, approval and denial appended to a per-client tamper-evident record, exportable as a workpaper for the client, their CPA, or your carrier.
Improves its models on its own schedule, and tells you afterwards.
Re-runs the same deterministic comparison on yours, and shows the arithmetic. A verification layer that never finds anything is not a verification layer.
Ships new features to QuickBooks Online only.
QuickBooks Desktop 2024 is frozen with no published end date. Whenever the client moves, the certificate and the tie-out are the same either way.
Do the arithmetic yourself. Intuit’s conversion is free; your hours are not.
Your clients, your hours, your rate are the only inputs. Nothing here is estimated for you, and there is no invented consultant rate to make the total look better.
Your inputs — nothing is estimated for you

Design-partner pricing, September 2026. No annual, volume, or BYOK discounts until we have measured what a close actually costs — we publish that number when we have it.
What we keep, where it goes, and what we refuse to call it.
Every check, every exception, every approval and every denial is appended to a per-client tamper-evident record. It says what was asked and what you decided. It is a workpaper, not a certification, and we do not call it one.
Transactions an agent compares are processed transiently under commercial API terms — not used to train models, retained 30 days by the provider. The subprocessor list is available on request.
Stored encrypted; deleted on your schedule. Ledger credentials are held only for the connections you authorize and revoked the moment you disconnect at /connect.
Questions bookkeepers ask
- Who is BookSyncHQ for?
- The reviewing owner of a small bookkeeping firm — two to nine people, twenty to a hundred QuickBooks Online clients, and a tail of QuickBooks Desktop files. Not business owners doing their own books, and not the top-100 CPA firms. The practitioners in between, who personally sign off on the most client-months per pair of hands.
- Do you compete with bookkeepers?
- No. Pilot, Digits, and Zeni sell bookkeeping to businesses; BookSyncHQ sells an independent check to bookkeepers. Your firm, your clients, your sign-off — we prove the numbers agree and hand you the workpaper.
- What stops an agent from posting a bad entry?
- We are not the agent that posts. BookSyncHQ compares — it re-derives the register from the bank statement and diffs it against the ledger in integer cents. Where a break needs a correction in the books, the correction is proposed and waits for you; journal entries and voids always wait. Every check, every exception, every approval and every denial is appended to a per-client tamper-evident record you can export as a workpaper. That is a supervision system, not a guarantee — you remain the professional of record.
- Where does the data live?
- Two honest answers. Processing: when an agent compares transactions, those transactions are processed transiently under commercial API terms — not used to train models, retained 30 days by the provider. Storage: your ledger data and the evidence record are stored encrypted and deleted on your schedule; ledger credentials are held only for the connections you authorize and revoked when you disconnect. The subprocessor list is available on request.
- Do I install anything?
- No. BookSyncHQ runs in your browser: connect QuickBooks Online or Xero once, then review exceptions, approve fixes, and export workpapers from any machine. QuickBooks Desktop files are handled through the reports you already export — nothing is installed on the client’s Windows box.
- Is there really a September 2027 QuickBooks Desktop deadline?
- No — and we used to say there was. Intuit has published no end-of-support date for QuickBooks Desktop 2024 — no discontinuation page for the 2024 line exists, and Intuit’s own pages say existing subscribers keep renewals, updates, and support. What is true: no new Desktop version has shipped since 2024, new Pro, Premier, and Mac subscriptions ended September 30, 2024, services for the 2023 line ended May 31, 2026, and renewals rise every February for a product that will not get new features. Intuit can announce a sunset whenever it chooses. That is a reason to be migration-ready, not to panic. Verified 2026-09-02 against Intuit’s own pages.
