Align your bank account with your books from day one: the setup sequence

The order is the whole trick

Setting up a new company's books isn't hard, but the sequence matters more than almost anyone tells you. Do the steps in the right order and your first month reconciles cleanly, every number ties to your bank balance, and the books more or less keep themselves after that. Do them out of order — or skip the boring middle steps — and you spend your first quarter chasing a discrepancy you can't explain, because something was missing from the start.

Here's the sequence for a newly funded UK startup, and why each step comes where it does. If you've just opened your business account (covered in Opening your startup's business bank account →), you're ready to start.

Step 1: Open the business bank account (already done, ideally)

This comes first because everything downstream reads from it. You can't connect a feed, set a starting balance, or reconcile anything until the account exists. If you haven't opened it yet, do that before anything else — it's the one step with a real lead time. Once it's live, don't wait days to connect it; move straight to step 2 while the account has zero or few transactions.

Step 2: Connect the bank feed to your accounting software

As soon as the account is open, link it to your accounting software so transactions flow in automatically rather than being typed in by hand. This is the single change that turns bookkeeping from a chore into something that mostly happens on its own — the feed brings every payment and receipt in, and good software categorises and matches them for you. The mechanics, and why it changes everything, are covered in How to connect your bank to your accounting →.

Connect it before you enter opening balances, so the software knows the account exists and can line the live feed up against the starting position you're about to set.

Step 3: Set your opening balances

This is the step most founders skip, and it's the one that makes or breaks your first reconciliation. Your opening balances are your company's financial starting position on the day you begin keeping books. For a freshly funded startup, that usually means:

• The cash in the bank — the round that landed, plus any founder money already in.
• Share capital and investment — the money investors put in, recorded against the shares issued, so your balance sheet reflects who funded the company.
• Anything already spent before the account existed — incorporation fees, a domain, a laptop, legal costs for the round — often paid personally and reclaimable, usually recorded as a director's loan (money the company owes you back).
• Anything already owed — an invoice you've received but not yet paid, for example.

Get these in and your books start from reality. Skip them and your first reconciliation will be off by exactly the amount you didn't record — and you'll burn an afternoon hunting for it. If your ownership and investment are at all involved, this is also the point to make sure your cap table matches what you're recording; see What is a cap table and how do I keep mine clean →.

Step 4: Let transactions flow — and categorise as you go

With the feed connected and the starting position set, your job becomes small and continuous instead of large and occasional. As payments and receipts come in, each one gets categorised — which expense it is, which invoice it pays, whether it's an asset or a cost. Good software does most of this automatically and only asks about the ones it genuinely can't place. See How to categorise bank transactions automatically →.

The key habit: keep it current. A few minutes a week (or software that does it for you) beats a lost weekend every quarter. This is the difference between books that stay clean and books that become a project.

Step 5: Do your first reconciliation

Reconciliation simply means checking that what your books say matches what the bank actually did — that every transaction is accounted for and the closing balance in your accounts equals the balance in your bank. Because you set your opening balances correctly and let the feed bring everything in, this first reconciliation should tie out cleanly rather than leaving a mysterious gap. If something doesn't match, it's usually one missing or miscategorised item, and it's far easier to find in month one than in month twelve. See Bank reconciliation without the headache → and, for the concept itself, What is reconciliation in accounting →.

Once that first month reconciles, you have a proven, trustworthy baseline — and every month after builds on it.

A worked example

Say your company incorporated on the 1st, you spent £600 personally on setup before the account existed, opened the business account on the 8th, and £150,000 of investment landed on the 10th. Your setup looks like this: connect the account's feed on the 8th; set opening balances showing £150,000 cash in, £150,000 share capital against the shares issued, and a £600 director's loan for the money the company owes you back for setup costs. Then as the round's cash gets spent — a £2,000 legal bill, a £900 cloud subscription, a founder's £3,000 salary — each flows in through the feed and gets categorised. At month end you reconcile: the books show exactly the bank balance, every pound is accounted for, and the £600 you fronted is sitting there as a loan for you to reclaim. Nothing to hunt down, because nothing was skipped.

Why this sequence protects you later

Setting up in this order isn't just tidy — it's what makes everything downstream honest. Your VAT (when you register) is calculated on correct figures. Your runway reflects real cash. Your investor updates tie to your bank balance. And when your next raise's diligence asks "do these numbers reconcile?", the answer is yes, from day one, with the trail to prove it. See How to answer investor due diligence →.

The founders whose books never become a crisis aren't doing anything clever. They opened the account, connected the feed, set the opening balances, and reconciled the first month — in that order — and then just kept it current. An afternoon of sequence at the start buys you years of books that look after themselves.

Frequently asked questions

What are opening balances and why do they matter?

Opening balances are your company's starting financial position on the day you begin keeping books — the cash in the bank, the share capital raised, and anything already spent or owed. Getting them right means your first reconciliation matches reality instead of being off by the amount you forgot to record.

In what order should I set up my books?

Open the business bank account, connect its feed to your accounting software, enter your opening balances, then let transactions flow in and do your first reconciliation. Doing it in that order means nothing is missing and the numbers tie out from the start.

Do I need to record spending from before the bank account existed?

Yes — money you or a founder spent personally to get the company going is usually reclaimable and belongs in the books, typically as a director's loan. Capture it in your opening position so those costs and the money owed back to you aren't lost.
