When your systems disagree, Mercury11 doesn’t guess.
Stripe and QuickBooks never quite match. Your accounting and marketing teams show up to the same meeting with different CACs. Mercury11 finds the conflicts, figures out why the numbers differ, gets the right person to settle them, and remembers the decision, so the same discrepancy never needs explaining twice.
No credit card. The trial starts at your first answer, not the day you sign up.
Findings 3 worth a look
A payout that lands lower than the charges behind it usually means refunds were netted out before the transfer, not that money is missing. There were $1,240 of refunds on Sep 15.
Which number do we reconcile deposits against?
Ask Metis
Yes, to the dollar.September payouts from Stripe total $412,300 and QuickBooks deposits total $412,300 once refunds are netted the way the rule says.
Two days needed the rule: Sep 16 ($1,240 of refunds) and Sep 23 ($560). Without it they would show as $1,800 unexplained. One item is still open: a $95 Stripe fee adjustment on Sep 30 that has not posted to the books yet.
One gap, explained once. The month ties out, and so does every month after it.
Three ways the gap gets handled today
Every pair of systems you run disagrees somewhere, every month. Payouts and deposits, ad conversions and analytics, jobs and invoices, won deals and the books. Here is what usually happens next.
Someone exports both sides, lines them up, and chases each difference by hand. Four hours if nothing is odd. A day if something is.
Cost
Every month
The differences are all known, to one person. Refunds net out of payouts. That customer always pays late. Nobody else can close the month without them.
Cost
One person
"Close enough." The gap gets written off, grows a little each month, and turns up as a surprise at tax time or in due diligence.

Unknown
The gap is not noise. It is a rule nobody has written down yet.

Every pair, every day, with the reason attached
Mercury11 compares each pair of systems continuously, finds every difference, and explains the ones it has seen before. The first time it meets a new kind of gap it asks the person who knows, and the answer becomes a rule. What is left is the short list that is actually worth a look.
Reconciliation stops being a monthly project and becomes a question you can ask.
How it works
Connect both sides
Sign in to your tools or paste a read-only key. Two sources is enough to start: the money side and the books, or the ads and the analytics. Mercury11 only reads; it never writes to either system.
We find every gap and ask about the new ones
Each pair is compared continuously, day by day and item by item. Known causes are explained automatically. A new kind of gap gets one plain question to the person who knows, and their answer becomes a rule with their name on it.
Ask whether it ties out
"Do Stripe and QuickBooks tie out this month?" gets a yes or a short list of what is still open, with the rules applied and the sources shown. Your bookkeeper, your accountant and you all get the same answer.

It never guesses, and it never writes to your books.
A tool that quietly averages a gap away, or posts an adjusting entry on its own, is worse than the gap. Mercury11 does neither.
Every connection is read-only, checked for write access before it is accepted. When two systems disagree, Mercury11 shows the difference, says what usually causes it, and asks. The person who knows answers in a sentence and that becomes a rule with their name on it. If two rules ever conflict, an admin settles it.
Every tie-out shows which sources it read and which rules it applied, so your accountant can check the work without asking you.
Questions a bookkeeper asks on the first day
Connect the two systems that never match. See the gap by tonight.
Stripe and QuickBooks, ads and analytics, jobs and invoices. Connect a pair, and Mercury11 shows you every difference with the likely reason attached, then asks only about the ones it has never seen. Free to start; the trial clock runs from your first answer.
Questions people ask first
Does it fix the books?
No, and that is on purpose. Mercury11 is read-only: it never posts an entry, never edits a transaction, never touches either system. It tells you exactly where the gap is, what usually causes it, and whether it is explained by a rule your business has already set. Fixing anything that needs fixing stays with you or your bookkeeper, with the list in hand.
Which pairs can it reconcile?
Any two sources you connect. The common ones are payments against books (Stripe, Square or Shopify against QuickBooks or Xero), ad platforms against analytics, CRM against books, and field-service or scheduling tools against invoices. If a system has no connection yet, drop an export in and it is compared the same way.
What if a gap is a real error, not a rule?
Then it stays open. Mercury11 only explains a difference when a rule covers it; everything else is listed as unexplained with the amount and the day, so the real problems do not get buried under the normal ones.
How often does it check?
Connected sources sync daily, hourly on the Scale plan, and every tie-out is recomputed on each sync. You can ask at any time and get the state as of the last sync, with the sync time shown.
Can my accountant use it?
Yes. Invite them as a viewer, or an editor if they are the person who knows the rules. Every answer shows the sources and rules it used, and any table exports to CSV.
Who owns the data?
You do. Connections are read-only, each business sits in its own isolated database, disconnecting a source deletes its data, and you can export every rule and answer in one click. We never train models on your data.
What does it cost?
One price for the whole company, not per seat. Plans start at $75 a month, month to month, no contract, with a 14-day free trial that begins at your first answer. See pricing.
