Monthly Bookkeeping Services
Monthly bookkeeping keeps your records ready for GST returns, management decisions and the year end. Each month we:
- Record your sales, purchases and expenses from invoices, receipts and bank feeds
- Reconcile every bank and payment account
- Track what customers owe you and what you owe suppliers
- Prepare a profit and loss statement and balance sheet you can review each month
- Keep records that explain every transaction, as the Companies Act requires
Our Pricing
Our accounting fees start from S$200 per month for monthly bookkeeping. The final fee depends on your transaction volume, the number of bank and payment accounts, whether you are GST registered, and the condition of your source documents. We also run quarterly, half-yearly and annual cycles, which are quoted separately because the work arrives in fewer, larger batches. Whether you need basic bookkeeping or full-scope finance management, our packages are modular and scale with you, from SMEs to large MNCs.
Send us one recent month of statements and we will give you a fixed fee before any work starts. For a full breakdown of what accounting costs in Singapore, read our accounting price guide.

Frequently Asked Questions About Outsourcing Accounting Services

Monthly bookkeeping suits most active companies, because GST returns, ECI and management decisions all depend on up-to-date numbers. Companies with few transactions can choose quarterly, half-yearly or annual cycles, which we quote separately. Whatever the cycle, the Companies Act requires records that explain every transaction, kept for at least five years.

If your company needs an audit, our statutory audit services take the year end through to the signed report: we close the books, prepare the schedules and draft financial statements, schedule the audit with your appointed auditors and answer their queries.
