A consultancy in Lisbon, six people, two bank accounts. One for the operating account, one that holds a reserve for taxes. Between the two, about 120 lines a month: client payments, supplier debits, card fees, the odd transfer to a freelancer.
The owner used to leave the bank alone until the 28th. Then she changed one habit, and the change is small enough to describe in a paragraph.
The Friday habit
Every Friday, for about thirty minutes, someone in the team opens the two accounts and looks only at the lines from that week. Not the whole month. Just the last seven days.
A typical week brings in around 30 lines. Most of them are not a decision at all. A client payment matches an invoice already issued. A recurring supplier debit matches last month's pattern, same amount, same day. A card fee matches the platform statement. Call this the easy pile: roughly 22 to 24 lines out of 30, matched by a rule the person already knows without opening a second tab.
That leaves five or six lines that need a look. A transfer with a reference that does not quite match a client name. A refund. A payment split across two invoices. These take two or three minutes each, because the trail is still fresh: the invoice was issued this week, the email is still near the top of the inbox, the person who made the transfer still remembers doing it.
And then one or two lines with nothing behind them. A debit with no receipt on file. A deposit with no invoice issued yet. These get a message the same day: to the team member who made the purchase, or to the client who paid without warning. Not a note for later. A message on Friday, while the week is still the week.
Thirty minutes, once a week, and by the end of it every line has a name.
What the 28th looks like instead
Contrast that with the company that waits. Same 120 lines, same six people, but nobody has looked at the bank since the last close. On the 28th, someone opens the account and finds 120 lines, cold.
Cold means the invoice for a payment from three weeks ago is buried under forty later invoices. It means the receipt for a supplier debit from the second week was a paper slip that has since been recycled. It means the person who can explain a strange transfer is on holiday, because it is nearly month end and people take holidays near month end.
The arithmetic gets worse, not better, with scale. Five unmatched lines discovered the same week take fifteen minutes to chase. Five unmatched lines discovered three weeks later, mixed in with fifteen other unmatched lines from other weeks, take an afternoon, several messages, and at least one "I don't remember what this was."
By the time the contabilista certificado asks for the month's documents, the company is not sending documents. It is sending apologies and a promise for next Tuesday. The accountant waits, the IVA deadline does not move, and the close that should take a morning takes most of a week, spread thin across everyone's patience.
The worked numbers
Take the month straight through. Four Fridays, thirty minutes each: two hours of bank matching for the whole month, done in small pieces while everything is still recent.
Compare it to the alternative: one sitting at month end, 120 lines cold, a realistic average of fifteen minutes per unmatched line once you include the chasing, the searching for old emails, and the back and forth with the accountant about what a line probably was. If a fifth of those 120 lines need real work, that is 24 lines at fifteen minutes: six hours, concentrated in the days right before a deadline, when everyone is least patient and the accountant is least available.
Two hours spread over a month, or six hours crammed into three days that always seem to include a public holiday or someone's absence. The total time is not even the main cost. The main cost is that the six hours arrive exactly when the company can least afford to lose them.
Why the close then takes a morning
By the time the month ends, every line already has a document, or already has a question that was answered weeks ago. There is nothing left to reconstruct. The contabilista certificado gets a clean set: invoices issued, invoices received, bank movements matched, IVA figures that were true all along rather than assembled at the last minute.
This is also where SAF-T and e-fatura stop being a scramble. If invoices were issued and matched as the weeks went by, the export is a formality, not an investigation. In Spain, the same logic applies to modelo 303 and to Verifactu records: the asesor works from a bank that was never allowed to go cold.
None of this needs new software to start. It needs a recurring thirty minutes and someone willing to send an awkward message on a Friday instead of hoping the line explains itself later. Tools like Cifrova Business exist to do the matching automatically and flag only what needs a human decision, but the habit works even with a spreadsheet, as long as it happens weekly and not monthly.
FAQ
How long should a weekly bank match actually take for a small company? For a six or seven person company with one or two accounts, thirty minutes a week is a reasonable target once the routine is established. The first few weeks take longer while you build the rules for recurring payments.
What counts as "unmatched" during a weekly check? Any bank line without a linked invoice, receipt or clear internal explanation. It does not need to be resolved that day, but it needs to be flagged and chased that day, while the trail is fresh.
Does this replace the accountant's own reconciliation? No. This is the company's own weekly hygiene, done before the books reach the contabilista certificado or asesor. It reduces the number of open questions they have to raise later, it does not remove their review. Ask your accountant what format they prefer to receive matched lines in, since this differs by firm.
