Bookkeeping Hub
Bookkeeping is the operating record of the business: every transaction captured, coded, reconciled and closed with the evidence to prove it. Sixteen practitioner guides on fundamentals, the accounting cycle, bank reconciliation, source documents, controls and month-end close — plus independent comparisons of the bookkeeping software and services that run it.
Explore bookkeeping by focus area
Good bookkeeping answers four questions on demand: what happened, where is the proof, does the ledger agree with the bank and the suppliers, and is the period closed. The guides in this hub are grouped around exactly those questions, from first principles to the month-end routine.
The bookkeeping operating cycle
Bookkeeping is a loop, not a filing task. Every period runs the same five moves: capture the transaction and its evidence, record it in the right account, reconcile the ledger to the outside world, close the period so the numbers stop moving, and report what the closed period says. Businesses that run this loop weekly close their books in days and rarely restate; businesses that run it once a quarter discover missing invoices, duplicate payments and unexplained bank items long after anyone can remember what happened.
The steps below are the backbone used across the guides in this hub. Steps one and two are covered in How Should Businesses Organize Source Documents? and Journal Entries and Ledgers Explained; step three is the subject of Bank Reconciliation; steps four and five connect to Adjusting and Closing Entries and How Does Month-End Close Work?. The full eight-step sequence is walked through in What Is the Accounting Cycle?.
- CaptureEvery sale, purchase, receipt and payment enters the system with its source document attached — invoice, receipt, contract, bank line. No document, no entry.
- RecordCode each transaction to the right account in the chart of accounts, with the date, counterparty and any project or department dimension the reporting needs.
- ReconcileAgree the ledger to bank statements, supplier statements, customer balances and payroll. Every difference gets a name and an owner, not a plug.
- ClosePost accruals, prepayments, depreciation and corrections; review the trial balance; lock the period so prior-month numbers can no longer drift.
- ReportProduce the statements and management pack from the closed ledger, then feed what the numbers show back into next month's priorities and controls.
Five bookkeeping health metrics — formulas and targets
| Metric | Formula | Healthy range | What a bad number usually means |
|---|---|---|---|
| Days to close | Working days from period end to locked ledger and issued management accounts | 5–7 working days for SMEs; 3 or fewer for best-in-class teams | Reconciliations left until month end, missing documents or approvals bottlenecked on one person |
| Unreconciled items | Count and value of bank, supplier and customer differences older than 30 days | Zero items over 30 days; nothing over 60 days at close | Bank feed not reviewed weekly, unposted receipts, or duplicate and mis-keyed payments |
| Source-document coverage | Entries with an attached or linked document ÷ all entries posted in the period | Above 98% for expenses; 100% for anything over the approval threshold | Card spend and expense claims bypassing the capture step; audit trail weakening |
| Post-close adjustments | Number and value of entries posted to a period after it was reported | Fewer than 3 per month and under 1% of revenue | The close is happening too early, or accruals and cut-off are being estimated by memory |
| Coding error rate | Entries reclassified in review ÷ all entries posted | Under 2% | Chart of accounts too long or ambiguous, or no written coding guide for the team |

Bookkeeping questions finance teams ask
What is bookkeeping and how is it different from accounting?
Bookkeeping is the systematic recording of every financial transaction — sales, purchases, receipts and payments — in the ledgers, supported by source documents and reconciled to bank and supplier records. Accounting takes that record and interprets it: adjusting entries, financial statements, tax positions and management analysis. Bookkeeping produces the evidence; accounting produces the judgement. In small businesses one person often does both, but the controls should still be separated in the workflow.
How often should bank reconciliation be done?
Monthly is the minimum for any business that produces management accounts; weekly is the practical standard for companies with more than a few dozen bank transactions a week; daily reconciliation is normal in cash-heavy retail, e-commerce and any business running an automated bank feed. The rule is that the reconciliation frequency should be short enough that an unexplained item is still easy to trace when it is found.
What are the steps of the accounting cycle?
The classic eight steps are: identify and analyse transactions from source documents; record journal entries; post to the general ledger; prepare an unadjusted trial balance; record adjusting entries for accruals, deferrals, depreciation and estimates; prepare the adjusted trial balance; produce the financial statements; and close the temporary accounts to retained earnings so the next period starts clean. Modern software collapses several steps, but the checkpoints — trial balance, adjustments, close — still have to be reviewed by a person.
What is a chart of accounts and how should it be structured?
The chart of accounts is the numbered list of every account the ledger uses, grouped into assets, liabilities, equity, revenue and expenses. A good chart is as short as the reporting actually needs, uses consistent numbering ranges (for example 1000s for assets, 4000s for revenue), separates operating from non-operating items and avoids catch-all accounts like 'miscellaneous expense'. Add dimensions (department, project, location) through tags or cost centres rather than by multiplying accounts.
How long does a month-end close take, and what is a good target?
A well-run small or mid-sized company closes the books in five to seven working days; best-in-class finance teams close in three or fewer. The close is long when reconciliations are left until month end, source documents are missing, intercompany balances disagree or approvals bottleneck on one person. Shortening it is mostly about moving work into the month — daily bank feeds, weekly AP and AR reviews, and a written close checklist with owners and deadlines.
Which bookkeeping controls prevent the most common errors?
Five controls catch most problems: segregation of duties between recording, approving and paying; bank and supplier statement reconciliations with a reviewer sign-off; a three-way match of purchase order, receipt and invoice before payment; a locked period once the month is closed so prior figures cannot drift; and a source-document rule that no entry is posted without a scan or link to its evidence. Together they stop duplicate payments, miscoding, missing invoices and weak audit trails.
Should a small business use bookkeeping software, an online bookkeeping service, or an accountant?
Most businesses use a combination. Cloud bookkeeping software (QuickBooks, Xero, Zoho Books, Sage, Wave, FreshBooks) is the system of record from day one. An online bookkeeping service or AI-assisted bookkeeping tool takes over transaction coding, reconciliations and month-end when the owner's time is worth more than the fee, typically past a few hundred transactions a month. An accountant adds tax filings, statutory accounts and advisory. The comparisons in this hub cover current pricing and fit for each category.
