How often should I do bookkeeping?
You should do bookkeeping at least once a month, but weekly is better. Monthly bookkeeping catches errors before they compound, keeps VAT filings accurate, and gives you a current view of cash flow. Weekly bookkeeping is ideal for businesses with 50+ monthly transactions or tight cash-flow management needs.
The frequency depends on volume and cash sensitivity. A business with 10 transactions a month can get away with monthly bookkeeping — it takes an hour and nothing falls through the cracks. A business with 200 transactions cannot: monthly means 200 items to process at once, which guarantees errors, missed receipts, and fatigue.
The real cost of infrequent bookkeeping is not the time — it is the accuracy loss. When you enter transactions three months after they happen, you forget what each receipt was for, you miss duplicates, and you cannot reconcile the bank statement because too many transactions have piled up. This is how clean books turn into a mess that requires a professional to unravel.
Weekly bookkeeping (30–60 minutes) is the sweet spot for most businesses. You process the week's transactions while they are fresh, reconcile the bank statement immediately, and always know your cash position. Tools like Nika push this to daily — invoices are filed the moment they arrive, so the bookkeeping is always current without you spending time on it.

What happens if I do bookkeeping only once a year?
Your accountant will charge more to untangle a year of mixed transactions. You will miss VAT deadlines (if registered), lose track of deductible expenses, and have no visibility into cash flow. Year-end bookkeeping is the most expensive and error-prone approach — it is false economy.
Can bookkeeping be fully automated?
The data-entry side (capturing invoices, entering transactions, matching bank feeds) can be automated. The judgment side (classifying unusual transactions, correcting errors, advising) still requires a human. AI bookkeeping like Nika automates the entry and sends anything unclear to a human for review.
