Three systems say three different things about the same month.

Shopify paid out. Link My Books posted a summary. QuickBooks banked a deposit. When those three stop agreeing, the difference hides in a clearing account and surfaces at year end. This finds it on the first of the month instead, payout by payout, with the dollar effect on the books and the fix written out.

Shopify payouts to Link My Books postings to QuickBooks deposits

What it catches

Thirteen checks run over every payout. Each one comes back with the amount it puts wrong in the books and what to do about it.

ProblemWhy it matters
Payout never postedShopify paid out and Link My Books sent nothing. Sales, tax and fees are all missing from the ledger.
Posted but never bankedThe entry is in QuickBooks, the deposit is not. It sits in the clearing account looking like income in transit.
Deposit with nothing behind itCash landed and was coded to sales. Usually an owner transfer or a loan, and it inflates revenue until someone traces it.
Posted twiceA re-sync created a second entry. Revenue, sales tax and fees are all double counted.
Banked twiceThe same deposit keyed in manually on top of the bank feed.
Net ties, breakdown does notThe bank reconciles perfectly, so nothing looks wrong, but sales tax was mapped to sales. This one survives for months.
Fees at the wrong amountApp charges and shipping labels netted into the payout but not into the fee account.
Cut-offThe payout belongs to one month and the cash cleared in the next. Correct, but it has to be shown as in transit.
Failed syncThe Link My Books entry errored on a missing tax code and nobody noticed.
Cent-level roundingSeparated out so it never gets confused with a real difference.

How a month runs

01

Three exports

Shopify payouts, the Link My Books settlement list, and the QuickBooks transaction list for the account the payouts land in. CSV or Excel. Columns are detected and shown back to you before anything is matched.

02

Match and read the bridge

Gross sales down to cash in the bank, then the two variances explained line by line. One page a client can actually follow.

03

Work the exceptions

Worst first. Mark each one fixed or no action needed, leave a note, then export the lot as an Excel workpaper for the file.

Where the data goes

Your exports are read in the browser and are never uploaded. That holds in the demo and it holds for client work: the matching runs on your machine, and the CSVs never go anywhere.

The demo goes further. No account, no server, nothing kept — close the tab and it is gone, which is what makes it safe to open before anyone has signed anything.

For client work there is a sign-in, and what is kept is the result: the summary, the bridge and the exception list with your notes, so next month knows what you decided this month. Each client's books sit behind their own access, enforced by the database rather than by the page you are looking at.
