At minimum, once a month. If you can manage it, once a week is significantly better.

Reconciliation means comparing the transactions in your accounting software to what actually cleared your bank account. You’re confirming that every deposit, payment, and transfer matches up and that nothing is missing or duplicated. When the two balances agree, you know your books reflect reality. When they don’t, something needs to be investigated.

Monthly reconciliation is the standard because bank statements come monthly. Most accountants and bookkeepers treat it as the baseline. If you’re only reconciling once a month, do it as soon as the statement closes. Waiting until you “get around to it” turns monthly into quarterly, and quarterly turns into year-end chaos where you’re trying to sort through hundreds of transactions with no memory of what happened.

Weekly is better because you catch problems faster. A duplicate vendor charge is easy to dispute when you notice it five days later. Three months later, your options are limited. The same goes for transactions that were categorized wrong or charges you don’t recognize. When the details are fresh, fixing them takes a few minutes. When they’re stale, it takes digging through emails and calling vendors.

For contractors and trades businesses, weekly reconciliation is especially valuable. You have materials purchases hitting every few days, subcontractor payments going out, customer deposits coming in, and sometimes multiple jobs running at once. That volume of activity means more chances for something to slip through. A $400 charge at a supply house that should have been coded to the Smith remodel ends up under the wrong job or sitting uncategorized. Catching that the same week keeps your job costs accurate.

Weekly reconciliation also gives you a real picture of your cash position. If you’re a contractor waiting on a draw payment and trying to decide whether to order materials for the next phase, you need to know exactly what’s in the account and what’s still outstanding. Relying on your bank app balance without reconciling is misleading because it doesn’t account for checks that haven’t cleared or pending charges.

The process doesn’t have to take long. If you’re keeping up with categorizing transactions as they come in, a weekly reconciliation might take ten or fifteen minutes. It’s the businesses that let everything pile up that end up spending hours untangling months of unchecked activity.

If you don’t have time to reconcile weekly yourself, that’s one of the first things a Long Beach bookkeeper handles as part of full-service bookkeeping. The important thing is that someone is doing it consistently. Reconciliation is the foundation that makes every other financial report trustworthy. Without it, your profit and loss statement, your cash flow projections, and your tax return are all built on numbers that might not be right.

Don’t let it pile up. Whether it’s weekly or monthly, pick a schedule and stick to it. The discipline of regular reconciliation is one of the simplest things you can do to keep your business finances under control.
