Close isn't done when every account has a number next to it. Close is done when every number ties to something outside your own books: a bank statement, a subledger, a report you didn't build. If it doesn't tie, it's a guess with good formatting.
"Tie out" is the term for that check, and if you've ever searched "tie out accounting" or "tie out meaning" trying to figure out what your bookkeeper keeps talking about, this is it. It's the habit that separates a close you can defend to an owner, a lender, or an auditor from a close that just looks finished. Some firms call the practice "tie out to zero reconciliation," since the whole point is landing on a $0.00 difference.
What does it mean to tie out the books?
Tying out means proving two independent totals agree, down to the penny. You take a number from your ledger and match it against a number from an outside source: the bank statement, a subledger, a processor report. The difference has to be $0.00. Not "close." Not "immaterial." Zero. A book that hasn't been tied out is a set of opinions about what happened. A book that has is a set of facts you can prove.
- Tie out means $0.00, not "close enough": two independent totals must match exactly before a period counts as closed
- Four standard tie-outs run every close: bank, credit card, AR subledger, AP subledger, each checked against an outside source
- A non-zero difference is almost always one of three things: a timing gap, a duplicate entry, or a bank fee that hasn't hit the ledger yet
- Check timing first: most differences clear themselves once you account for what hasn't posted on either side yet
- Untied numbers compound: a $12 miss this month is still there next month, just harder to find
- Tying out is a checklist, not a feeling: "the numbers look right" isn't a tie-out; a matched total is

Get startedEvery close runs the same four checks, each against a source you don't control:
- Bank. Ledger cash balance matches the bank statement ending balance.
- Credit card. Ledger balance matches the card issuer's statement balance.
- AR subledger. The accounts receivable subledger total matches the AR balance on the general ledger.
- AP subledger. The accounts payable subledger total matches the AP balance on the general ledger.
Four checks. Four outside sources. Four $0.00 differences. Skip one and you've closed three-quarters of the books.
A non-zero tie-out isn't a crisis. It's almost always one of three things, and there's an order worth checking them in.
Timing first. A check written on the 30th that clears on the 3rd shows up on one side and not the other. Same with a card swipe that posts to the ledger before the issuer settles it. Most differences close themselves once you account for what's still in transit.
Duplicates second. A transaction imported twice, once from a bank feed and once from a manual entry, inflates one side and nothing on the other. Pull the transaction list and scan for repeats.
Fees third. Bank fees, card processing fees, and NSF charges hit the bank statement before they hit the ledger. If timing and duplicates don't explain the gap, check for a fee the ledger hasn't recorded yet.
Work through those three before you assume the software is wrong. It usually isn't.
Tying out isn't a standalone task. It's the verification layer sitting on top of bank reconciliation: reconciliation matches transactions one by one, and tying out confirms the resulting totals actually agree. Both belong in a repeatable month-end close checklist, run in the same order every period so nothing gets skipped when you're rushing to close by the 5th.
Growthy's monthly close workflow tracks each of the four tie-outs as its own checklist item. A period can't get marked closed with an untied balance sitting underneath it.
A close that "looks right" and a close that's tied out are different things. One is a feeling. The other is proof. Run the four tie-outs, check timing first when something's off, and don't call a period closed until every difference reads $0.00.
