How to track bills without connecting your bank

Write down the bills you know are coming, mark them paid the moment they leave your account, and keep whatever’s left in one place you check without dreading it. That’s the entire system — no formulas, no categories, no dashboard to interpret.

It sounds almost too simple, but simple is what survives a busy month. A feed that quietly logs six hundred transactions is worse than a list of eleven bills you actually read, because you never open the six hundred, and you always open the eleven.

Say your bills are rent (£850, due the 1st), electricity (£64, due the 9th), phone (£28, due the 14th), and a car payment (£210, due the 22nd). That’s the entire unpaid column at the start of the month. As each leaves your account, it moves to settled. Nothing about that requires a bank feed — it requires four lines and thirty seconds each time one clears.

Open Banking is convenient, but it means a third party reads every transaction you make, forever, to show you a dashboard you’ll glance at twice a week and mostly ignore the other five days. The convenience is real; so is the trade you’re making for it, and it’s worth naming rather than accepting by default.

A manual bill tracker flips that trade: you type in what matters — the bill, the amount, the due date — and nothing else leaves your hands. There’s no permission screen, no read-only token sitting with a third party, no risk that a breach at that provider exposes years of your spending history. The data footprint is exactly as big as what you chose to enter, which for most people is a dozen or two recurring bills, not thousands of coffee purchases.

It also tends to be more accurate for the one number that matters. A bank feed shows you a raw balance; it doesn’t know that £850 of what’s sitting there is already spoken for by Friday’s rent. You end up doing the subtraction in your head anyway — a ledger just does it for you, on purpose, with numbers you chose to put in.

Three states cover almost every bill: unpaid (coming up), settled (already gone), and leftover (what’s free once both of those are accounted for). Resist the urge to add a fourth or fifth state — “pending,” “disputed,” “partial” — until you’ve actually hit a case that needs one. Most months, you won’t.

Anything more granular than that is usually decoration. The goal is a number you trust, not a spreadsheet you maintain — it’s the same three-way split Billify runs on internally, because there’s rarely a good reason to track more than that. A category breakdown of “utilities vs subscriptions vs insurance” answers a curiosity question once a year at most; unpaid/settled/leftover answers the question you actually ask every single day, which is simply: can I spend this?

Start by listing every recurring bill you can think of — rent or mortgage, utilities, phone, internet, insurance, subscriptions, any regular transfer to a family member or a loan repayment. Most people land somewhere between eight and twenty lines. Write the amount and the due date next to each.

Add your income next — payday amount and date, or if it’s irregular, your lowest realistic figure for the month (there’s a separate guide on budgeting with irregular income if that’s your situation). Once both lists exist, leftover is just income minus unpaid minus settled, recalculated the moment anything changes.

From there, the only ongoing work is marking a bill settled when it actually leaves your account, and adding anything new the moment you commit to it — a subscription you sign up for, a one-off cost you agree to. Do that consistently and the system stays honest without ever becoming a chore.
