OCTIS vs accounting firm or online bookkeeping service in Hong Kong
What each costs, what it covers and who it suits.
Last checked · 6 sources
Otty's short answer
Online services publish prices: bookkeeping from HK$3,500 per financial year at Sleek and Osome, or from HK$891 per month at Statrys. Local accounting firms usually quote by scope, so ask for a fixed fee. DIY software costs from US$7 per month but leaves the books and filings to you. Use an online service for simple books, a firm for advice or complex cases.

What the table does not show
What you actually get for the price
Sleek's Basic plan is HK$3,500 per financial year and covers annual bookkeeping, unaudited financial statements, the employer's return and management reports. Standard is HK$5,880 per year with monthly bookkeeping, monthly statements and monthly payroll. Osome's Operate plan is HK$3,500 a year for revenue under HK$200,000. Statrys charges by transactions, from HK$891.67 per month. Firms rarely publish prices, so ask for a written scope.
The audit is a separate job
Bookkeeping does not replace the yearly audit. Hong Kong companies must have audited accounts unless they are dormant, and the Inland Revenue Department expects audited statements with the profits tax return. An accounting firm may run both bookkeeping and audit, but auditor independence rules mean a CPA practice generally should not audit books it prepared itself. Check who signs the audit report and whether that practice is separate from your bookkeeper.
When to move from online to a firm
Online services work well while your books are repeatable: one entity, a few bank accounts, simple invoices. Move to a firm, or add one for advice, when you restructure, hold offshore income, claim an offshore tax exemption, raise investment or open a second entity. Sleek's own audit plans separate companies with assets above HK$10 million or offshore arrangements into a higher tier, which shows where complexity starts.
Where OCTIS fits
OCTIS sits between the two: AI does the routine bookkeeping and tax work, and licensed professionals check it, with the audit done by a Hong Kong CPA practice. If you pay a firm or an online service today, send us your current bill and we come in 10–30% off it.
Frequently asked questions
How much does bookkeeping cost for a small company in Hong Kong?
Published online prices start at HK$3,500 per financial year at Sleek and Osome, and HK$891 per month at Statrys. Higher transaction counts and monthly service cost more. Local firms normally quote by scope.
Do I need an accountant in Hong Kong?
The law needs proper books, an audit by a practising CPA unless the company is dormant, and a profits tax return. It does not say who keeps the books. A bookkeeper, an online service or an in-house person can do it.
Is online bookkeeping accepted by the IRD?
The IRD asks for accurate records and, for companies, generally audited financial statements. It does not care which tool produced the books, as long as the records are complete.
Can the same firm do my books and my audit?
Often yes within one group, but the auditor must stay independent of the work they audit. Many companies use a separate CPA practice for the audit.
What is cheaper, Xero myself or an online service?
Xero Lite costs from US$7 per month, but you do the work. An online service from HK$3,500 per year includes someone reconciling and preparing statements. Compare your time cost, not just the fee.
