Detailed Guide on Bookkeeping and Accounting

Bookkeeping and Accounting Are Not the Same Job

Ask a small business owner who handles the finances and you will often hear "our accountant keeps the books". The two words get used interchangeably, but they describe different stages of the same work. Bookkeeping is the disciplined, day-to-day recording of every financial transaction. Accounting takes those records and turns them into financial statements, analysis and compliance filings that management, lenders and regulators can rely on.

Think of a hospital. Nurses record blood pressure, heart rate and medication on the chart, accurately and on time. The doctor reads the chart, makes a diagnosis and decides on treatment. A doctor cannot diagnose from an incomplete chart, and the chart on its own does not tell the patient what to do. Bookkeeping is the chart; accounting is the diagnosis.

This guide explains each stage, works through a month of transactions for a small trading company, shows how adjusting entries change the picture, walks through a bank reconciliation, sets out the Saudi requirements that apply, and ends with a monthly close checklist and the role an ERP plays in connecting the two.

What Bookkeeping Covers

Bookkeeping means recording the business's financial transactions systematically and in sequence, each supported by a source document. Every sale, purchase, payment and receipt should be recorded promptly, in the right account, for the right amount.

• Collecting and filing documents: sales and purchase invoices, receipts and payment vouchers, bank statements, leases, payroll registers.
• Recording journal entries: every transaction as a double entry, with equal debits and credits.
• Posting to the general ledger: grouping entries into accounts so each balance is visible: cash, receivables, inventory, sales.
• Managing receivables and payables: who owes the business, whom the business owes, and when.
• Bank reconciliation: matching the bank balance in the books to the statement and explaining every difference.
• Preparing the trial balance: a list of all account balances where total debits equal total credits.

Why double entry matters

Every transaction touches at least two accounts. Buy SAR 10,000 of stock for cash and inventory rises by 10,000 while cash falls by 10,000. That balance makes many errors detectable: a trial balance that does not balance means something was recorded wrongly. But balance is not proof of accuracy. Post the right amount to the wrong account and the trial balance still balances.

What Accounting Adds

Accounting starts where bookkeeping stops. The accountant applies accounting standards to the records, prepares statements, analyses results and advises.

• Adjusting entries: depreciation, accrued expenses not yet invoiced, prepayments, deferred revenue, allowance for doubtful debts.
• Financial statements: income statement, statement of financial position, cash flow statement, changes in equity, and notes.
• Management analysis: margins by product or branch, actual versus budget, liquidity measures.
• Tax and zakat: VAT returns and the zakat or income tax return.
• Budgeting and forecasting: expected revenue, costs and cash for coming periods.
• Internal control: procedures that prevent errors and fraud, such as segregation of duties and approval limits.

In Saudi Arabia, companies report under IFRS as endorsed by SOCPA: listed entities since 2017 and other entities since 2018, with IFRS for SMEs available as an option.

Cash Basis vs. Accrual Basis

One concept separates simple record-keeping from sound accounting. On a cash basis, revenue is recorded when money comes in and expenses when money goes out. On an accrual basis, revenue is recorded when it is earned, on delivery of goods or performance of a service, and expenses when they are incurred, whatever the payment date.

Hypothetically, a maintenance company signs a SAR 120,000 annual contract and the client pays it all in January. On a cash basis, January shows SAR 120,000 of revenue and the other eleven months nothing from that contract. On an accrual basis, the full amount is recorded as deferred revenue in January and SAR 10,000 is recognised each month as the service is delivered. The second view is the true one, because the company still owes eleven months of work.

IFRS is built on accrual accounting. A business that keeps cash-basis books will need extensive year-end adjustments to produce acceptable statements. It is far easier to design procedures on an accrual basis from the start.

Side-by-Side Comparison

Worked Example: A Trading Company's First Month

This is a simplified, hypothetical example. A new VAT-registered trading company records these transactions in its first month:

That is bookkeeping. Stop here and the apparent profit is sales 40,000 less cost of sales 26,000 less salaries 8,000 = SAR 6,000.

At month-end the accountant posts adjusting entries:

• Depreciation on office furniture and equipment for the month: SAR 1,200.
• The electricity bill has not arrived; estimated usage of SAR 900 is accrued.

Profit after adjustments: 6,000 less 1,200 less 900 = SAR 3,900, 35% lower than the unadjusted figure.

On VAT, output tax is 6,000 and input tax 7,500, a net SAR 1,500 in the company's favour for the period. The accountant still needs to check that every purchase invoice meets the conditions for input tax recovery before filing.

The lesson: accurate books are necessary but not sufficient. A manager reading the trial balance before adjustments would think the business is doing much better than it is.

Worked Example: A Bank Reconciliation

Also hypothetical. At month-end the bank balance in the books is SAR 84,500 and the statement shows SAR 79,350, a difference of 5,150. Review finds:

• A cheque to a supplier for SAR 6,000, recorded in the books but not yet cleared.
• A customer transfer of SAR 1,200 received by the bank but not recorded.
• Bank charges of SAR 350 not recorded.

Adjusted statement balance: 79,350 less 6,000 = 73,350. Adjusted book balance: 84,500 plus 1,200 less 350 = 85,350. A SAR 12,000 gap remains. Further digging finds an electronic supplier payment of SAR 12,000 that left the bank with no entry in the books. Once recorded, the book balance is 73,350 and matches.

Without the reconciliation, the supplier's balance would be overstated by SAR 12,000, the business might pay it again on the next statement, and available cash would look higher than it is. Reconcile at least monthly, and weekly if volumes are high.

Saudi Requirements That Shape Your Books

Commercial books

The Commercial Books Law (Royal Decree M/61, 1409H) requires merchants to keep books, including recording inventory at year-end, and to retain them for ten years. On 27 October 2026 the Council of Ministers approved a new Commercial Transactions Law that replaces the Commercial Law, the Commercial Papers Law and the Commercial Books Law, effective 180 days after publication in Umm Al-Qura. Watch for the implementing details as they are issued.

VAT

The rate has been 15% since July 2020. Invoices and records must generally be kept for at least six years, eleven years for records relating to movable and intangible capital assets, and fifteen years for real estate.

E-invoicing

Phase 1 (generation) started on 4 December 2021 and Phase 2 (integration with ZATCA) has been rolled out in waves since 1 January 2023. Wave 24 covered businesses with turnover above SAR 375,000, integrating between April and June 2026. Wave 25 covers those above SAR 187,500, due from 1 February 2027. E-invoicing tightens sales bookkeeping because every invoice comes from a compliant system and cannot be edited once issued.

Zakat

The new Zakat Executive Regulations apply to financial years starting on or after 1 January 2024. The zakat base is built from the financial statements, so the quality of your books and adjustments flows straight into the return.

Who Does What

In a small business one person may do both bookkeeping and accounting. That is fine as long as someone independent, the owner or an outside firm, reviews the work regularly. One person recording, approving and paying is a textbook control gap.

Outsourcing can make sense for start-ups with few transactions, for specialist needs such as zakat, or during a gap after an accountant leaves. A model that works well keeps daily bookkeeping in-house, close to operations, and gives the outside firm monthly review, adjustments and filings, with controlled access to the system rather than spreadsheets sent by email.

Setting Up the Chart of Accounts

• Clear levels: assets, liabilities, equity, revenue, expenses, then sub-groups.
• Enough detail, not too much: a separate account for each significant expense type, but not one per supplier; that is what sub-ledgers are for.
• Separate VAT accounts: input and output VAT in their own accounts to simplify returns.
• Cost centres instead of duplicate accounts: one salaries account with a cost centre per branch, not "Riyadh salaries" and "Jeddah salaries".

Monthly Close Checklist

1. Are all sales and purchase invoices for the month recorded?
2. Are all bank accounts reconciled with differences explained?
3. Do customer and supplier balances agree with statements?
4. Are depreciation, accruals and prepayments posted?
5. Does inventory in the ledger agree with the detailed stock report?
6. Do VAT accounts agree with issued and received e-invoice reports?
7. Has the accountant reviewed unusual manual journals?
8. Have results been compared with budget and last month, with large variances explained?

A disciplined monthly close turns year-end into a week instead of two months and makes the external audit shorter and cheaper. For the wider set of problems finance teams face, see our article on accounting challenges, and for the statement all this work feeds, our guide to the balance sheet.

How an ERP Connects the Two

In an integrated ERP much of the manual bookkeeping disappears, because entries are generated by the operations themselves. A sales invoice records revenue and VAT, reduces stock and posts cost of sales in one step. A goods receipt updates inventory and payables. Payroll posts straight to the ledger. The accountant's role does not go away; it shifts from re-keying to reviewing, adjusting and analysing. Read more in our article on accounting automation.

Tranquil is a cloud ERP in which financial accounting is integrated with ZATCA e-invoicing for Phase 1 and Phase 2, sales, purchasing, inventory, payroll and asset management with automatic depreciation. It includes bank integration for direct salary transfer and scheduled reports with deadline alerts. Contact the team to review your chart of accounts and close procedures.

Frequently Asked Questions

Can one person handle both bookkeeping and accounting?

In a small business, yes, provided an independent party such as the owner or an outside firm reviews the work regularly to compensate for the lack of segregation of duties.

How long must accounting records be kept in Saudi Arabia?

The Commercial Books Law sets ten years for commercial books. For VAT, at least six years in general, with longer periods for capital assets and real estate. Follow the new Commercial Transactions Law once it takes effect.

What is the difference between a trial balance and a balance sheet?

A trial balance is an internal list of all account balances used to check that debits equal credits. A balance sheet is a formal statement of assets, liabilities and equity after adjustments, prepared under accounting standards.

Does an ERP remove the need for an accountant?

No. It automates recording and posting, but adjustments, estimates, analysis and reviewing returns need professional judgment.

How often should we close the books?

At least monthly. A monthly close catches errors early, gives management current numbers and makes VAT filing and year-end far easier.
