Your company's
entire back office
Company secretary, bookkeeping, payroll, bank reconciliation, statements, tax — incorporation is just the start. Everything after it gets done for you: the system does the work, and a licensed Hong Kong CPA stands behind it.
You don't do bookkeeping. You occasionally answer questions only you can answer — "Is this the company account?" "Was this order delivered?" — and they get rarer over time.
Six jobs, taken off your desk
You don't need to know accounting or code. Each of these is a job done for you — not software handed to you.
Accounting
Toss in invoices, receipts and contracts: sorted and booked automatically, and anything unclear comes back as one question for you. Year-end statements prepared for a CPA.
See how it works for you ↓Company secretary
Registered address, statutory registers, annual return (NAR1), BR renewal, mail scanned and delivered — we watch the deadlines.
Payroll
Salaries and MPF worked out monthly, and the pay run lands in the books by itself.
Bank reconciliation
Every statement line finds its place; whatever doesn't match is listed openly, waiting on one word from you.
Financial statements
Balance sheet, P&L and cashflow ready at year end — every figure traceable to its document.
Tax & audit
Profits tax computed and deadlines watched; come audit season, the full evidence chain goes to the auditor.
Bookkeeping, off your plate
You only do the first two steps — everything after happens in the background.
Connect revenue and banks
Stripe and your bank accounts feed in on their own.
Toss the paperwork in
Invoices, contracts, receipts: drag into the web app, forward an email, snap a photo on Telegram.
Sorted and booked, automatically
Filed neatly, entries booked; anything uncertain stops and asks you. It never guesses.
Year-end statements, audit-ready
Balance sheet, P&L and cashflow prepared with the evidence chain intact — straight to the auditor.
This isn't "software plus good luck": our in-house, licensed Hong Kong CPA — practising certificate on file — stands behind the statements.
We can promise that because of three hard rules
The model never decides money
AI reads evidence and proposes accounts. Amounts, direction and the entry itself are decided by deterministic code — no suggestion reaches the ledger unless the code verifies it.
Unexplained money is never booked
Anything uncertain parks in suspense as a visible to-do, waiting for one word from you. The system never invents a story on your behalf.
Every figure is three hops from source
Entry → document → the exact line in the original. Whenever an auditor arrives, the path holds.
Three hops to the source
Pick any number. The entry card names the document it cites; one more tap and the exact line lights up in the original. Auditors don't want an explanation — they want a path that holds.
The receipt arrives
Photo, forward or API — registered as evidence before anything is booked.
The entry is booked
AI proposes the account; code fixes amount and direction. Debits equal credits, always.
Tap the figure
The exact line lights up in the original. Three hops, done.
Watch it say no
HKD 20,000 lands in the account. The reference just says "payment" — no invoice, no contract. It looks like revenue; it's actually a director repaying a loan.
“No evidence for this money — parked in suspense. We don't guess.”
Parks it in suspense (9999) as a visible to-do, waiting for one word from you. Nothing leaves suspense — and no report ships — until it's explained.
Book it as revenue — profit is overstated, and so is the tax.
A refusal is a visible gap. A wrong entry is silent rot that every later report inherits. We choose the gap.
Before any update ships, it must pass a full year of books
A company's complete year of accounts lives inside our system — revenue, refunds, foreign currency, disputes, tax. If a change puts any figure off by even one cent, that update never ships. To the cent, every time.
Accounting correctness isn't a policy here. It's a gate.
Bookkeeping that follows your habits
You don't open an accounting app. Evidence arrives from wherever you already are, into a single pipeline.
Web upload
Drag it into your files area and you're done — sorting isn't your job.
Email forward
Forward a receipt to your dedicated inbox, then forget about it.
Telegram photo
Snap a photo, send it to the bot — the reply is the filing confirmation.
Stripe / bank API
Platform and bank data flow in directly, matched line by line.
Bring your own agent
Connect your own agent — Claude Code, Cursor — to the real ledger over MCP.
Every door leads to the same evidence pipeline: the document is registered before anything is booked, and identical bytes are only filed once.
Moving in from Xero, QuickBooks or anywhere else
Hand us the export files and a real accountant carries the migration: opening balances arrive item by item with their sources, account mappings confirmed by a person. Running both systems during the transition is fine — we only trust documents and the bank, so the same receipt is never booked twice. After the cutover date, this is the only set of books.
Hong Kong's rules, down to the clause
Not "supports Hong Kong" as a bullet point — a citation behind every claim.
HKFRS chart of accounts
The chart is modeled on IAS 1 line items; every entry type in the catalog carries its official source — no invented categories.
Profits-tax deadline registry
Filing deadlines are a verified, year-by-year registry with sources, not a formula. When the IRD circular changes, the registry changes; years without a source are refused, never guessed.
A signing accountant
Statements are signed off only by a Hong Kong CPA holding a current practising certificate. Accounting policies are set once by the accountant — code merely enforces them.
TCSP licensed
Company secretary services are provided by a licensed Trust and Company Service Provider (Licence TC007253).
Your ledger doesn't lock you in
Bookkeeping providers can disappear. Your books must not disappear with them.
Append-only, forever
Entries are never edited or deleted. Corrections are new entries, so history stays whole and inspectable.
Export everything, any time
Entries, original documents, reference chains and working papers — packaged and portable.
Hand it to anyone
Give the package to any accountant or auditor: every figure still traces in three hops.
