Bookkeeping · Audit · Hong Kong
Certanta is a human-led, AI-assisted bookkeeping, ledger and audit-management service for Hong Kong businesses and the accountants who serve them. AI does the heavy lifting; a real bookkeeper makes sure it's right.
Always audit-ready. Always someone to talk to.
The problem
The work that should take minutes eats weekends — and the mess surfaces at year-end.
Every receipt, invoice and bank line is re-keyed by hand. Hours disappear, and typos slip into the books.
"Which account does this go to?" Inconsistent coding turns year-end into a clean-up project.
Records are pulled together only when the audit lands — reconciling twelve months all at once.
Spreadsheets, PDFs, bank portals and email that don't talk to each other. Nothing is the single source of truth.
The big idea
Hand over a batch of receipts, invoices and statements. Certanta reads, codes and books each one into a balanced, audit-traceable ledger — so neither you nor an in-house bookkeeper does the data entry.
How it works
Drop in a batch of receipts, invoices and PDF / CSV statements — all at once.
Vendor, amount, currency and date are extracted from each document — no fields typed.
The right account is suggested from your chart of accounts.
A balanced debit + credit is written to the ledger as true double-entry.
Matched against your uploaded statement and flagged audit-ready.
Your only job is step 1. Certanta runs steps 2–5 — checked by a real bookkeeper.
The human difference
We use AI to do the heavy lifting — but people own the outcome. Certanta uses AI; we're not an AI company.
AI reads, codes and reconciles — then a person checks the numbers before they reach your books.
Reach a real bookkeeper for questions or guidance — not a chatbot or a ticket queue.
We adapt to your files, your pace and your process — not the other way around.
Automation removes the busywork; the judgment calls stay with people.
One complete system
Twelve linked modules sharing one ledger — the same architecture running in production today.
For business owners
Built so the person running the business doesn't need to be an accountant.
Audit-ready books for a fraction of a full-time bookkeeper's salary, MPF and overhead.
Bulk-upload a month of documents and get current books back in days — not lost weekends.
Certanta proposes the treatment and does the books — and a real bookkeeper reviews every entry.
Real-time numbers across HKD, USD, CNY and more — converted automatically.
For CPAs & auditors
Rigour and traceability are built in, so engagements move faster and cleaner.
Every posting is a balanced pair with a complete, timestamped history.
Each entry links to the receipt or invoice that created it — one click to evidence.
A chart and statements that map to the frameworks you report under.
Multi-entity by design — review several engagements without switching systems.
Built for Hong Kong
Functional currency in HKD with automatic FX on USD, CNY, EUR and more.
Structured for the annual statutory audit and the Profits Tax return cycle.
Chart of accounts and statements follow the frameworks HK companies report under.
Books that stay current — so your CPA and filings are never waiting on a clean-up.
