客戶的幣散在交易所、錢包、託管,甚至橫跨香港與新加坡兩地,年審時只丟給你一堆 CSV?家辦 FIHV 申報、加密公司報稅——歸集、成本、證據鏈,一次理清。 客戶真名鎖在貴所手裡,平日全化名運作,出稿用印那一刻才解鎖。Client assets scattered across exchanges, wallets and custodians, often across Hong Kong and Singapore — and at year-end all you get is a pile of CSVs? FIHV filings and crypto-company tax: aggregation, cost basis and the evidence chain, sorted in one place. Real names stay locked with your firm — pseudonymous day to day, unlocked only at the moment of sealing.

港 · 新 跨境HK · SG CROSS-BORDER

橫跨香港與新加坡,一條證據鏈One evidence chain across Hong Kong & Singapore

加密家辦與企業的資產,越來越常同時落在香港與新加坡——交易所、錢包、託管分處兩地。歸集、配對、成本基礎、證據鏈不分轄區,一個客戶檔案全部理清。Crypto family offices and companies increasingly hold across both Hong Kong and Singapore — venues, wallets and custodians split between the two. Aggregation, matching, cost basis and the evidence chain are jurisdiction-agnostic — one client file, sorted end to end.

點擊切換該地口徑 ↓Tap a city to switch its filings ↓

一台引擎,兩條線(香港)One engine, two service lines (HK)

歸集、配對、成本基礎完全共用——差別只在最後一層出什麼底稿Aggregation, matching and cost basis are fully shared — the lines differ only in the final working papers

家辦線 · 香港家辦(FIHV)Family office line · Hong Kong (FIHV)

香港家辦盯著的是那 0% 優惠稅率,但要證明合資格,加密這塊最難說清。我們替貴所把它理成一份審計師認、稅局問得住的底稿——0% 站得住、年審不趕工,家族的真名平日全鎖著,出稿用印那一刻才解開。Hong Kong family offices are after the 0% concession — and crypto is the hardest part to prove qualifies. We turn it into papers auditors accept and the IRD can't fault: the 0% holds and year-end isn't a rush, with the family's real name sealed until the moment you issue the final report.

企業線 · 公司報稅Corporate line · company tax

香港的加密公司,年審、報稅一年一輪——加密那塊最容易在賬上對不上。我們把整年的買賣理成一份對得上、查得到的底稿:利得稅算得清清楚楚,CARF 時代交出去也經得起盤問。For crypto companies in Hong Kong, audit and profits-tax filing come round every year — and crypto is what refuses to reconcile. We turn a year of trades into reconciled, traceable papers: profits tax laid out clearly, and books that stand up to scrutiny in the CARF era.

三件事,做到審計等級Three things, done to audit grade

不是又一個組合追蹤器——是按會計師事務所的內控語言設計的工作底稿引擎Not another portfolio tracker — a working-paper engine designed in the language of a CPA firm's internal controls

身份保險箱Identity vault

家辦最怕的,是名字和持倉連在一起。日常介面只見化名,真名鎖進保險箱,鑰匙只在貴所手裡——連我們自己也打不開。只有出帶真名的終版文檔時開一次鎖:開一次,記一筆。What family offices fear most is a name attached to a position. Day to day you see pseudonyms only; real names sit in a vault and only your firm holds the key — we cannot open it ourselves. It unlocks once, to issue a named final document — and every unlock is on the record.

審計師問一句,答得出三句Every number can explain itself

每個數字都點得開:來自哪家交易所、哪份月結單、哪一批導入、成本怎麼一步步算出來。轉倉不斷成本,賬對不上當天就報警——年審季不用回頭翻半年前的郵件找數。Every figure opens up: which exchange it came from, which statement, which import batch, how the cost was built step by step. Transfers never break cost basis, and mismatches raise a flag the same day — no digging through six-month-old emails at year-end.

職責分離Segregation of duties

同事日常處理,敏感動作(解密真名、刪批次、改權限)必須主管過一道——如同用印。誰做的、誰批的,審計日誌一條條記著:出了問題,追得到人和那一步。Staff handle the day-to-day; sensitive actions (decrypting names, deleting batches, changing permissions) always go past a partner — like applying the firm's chop. Who did it, and who approved it, sits on the log line by line.

從接入到出稿From onboarding to sign-off

所有連接只能看、不能動客戶資產;客戶只給 Excel 也照收Every connection can look but never touch client assets; plain Excel is welcome too
01接入Connect客戶給什麼都能接:交易所、錢包、託管月結單、甚至一堆 Excel——匯成一個客戶檔案Whatever the client hands you: exchanges, wallets, custodian statements, even a pile of Excel — one client file
02每天自動理賬Books itself, daily自動同步、自動對帳,賬實對不上當天提醒——不是年審時才發現Syncs and reconciles itself; mismatches flagged the same day — not discovered at year-end
03化名報表Pseudonymous reports持倉、損益、成本底稿隨時拉——客戶問起來,當天就給得出,全程化名Holdings, P&L and cost working papers on demand — when the client asks, you answer the same day, pseudonymous throughout
04終版用印Final sealing年審出稿按期間批量授權,真名只在這一刻解鎖——蓋印留痕;修訂不覆蓋,舊版永遠留檔Batch authorisation per reporting period; names unlock only at this moment — sealed and logged. Revisions never overwrite; prior versions stay on file

資料接入,客戶自己來Data intake your clients handle themselves

一封邀請開一次門——客戶自行連入全部來源;每一條經貴所審批/核對才生效One invitation opens one door — clients connect all their own sources; every line takes effect only after your firm's approval
01一封邀請=開門One invite, one door貴所不必知道客戶有幾個賬戶:邀請綁定客戶本人(72 小時單次,僅首次開通用),客戶進門自報全部交易所、錢包、託管——同所多賬戶各自成條You needn't know how many accounts the client holds: the invite binds the client (72-hour, single-use, first entry only), and they list every exchange, wallet and custodian themselves — multiple accounts per venue, each its own line
02憑據不經貴所之手Credentials never pass through youAPI Key 由客戶自填、直達加密庫,貴所全程只見指紋;冷錢包地址當場簽名歸屬證明並留檔——審計師可獨立重驗API keys go straight from the client into the encrypted vault — your firm only ever sees a fingerprint; wallet addresses are proven by a message signed on the spot, archived for auditors to re-verify independently
03每一條過貴所的關Every line passes your desk連接啟用前主管審批——系統先驗只讀權限、賬戶歸屬、身份鏈;客戶上傳的檔案先核後入、不符可退回——入賬權永遠在貴所Connections activate only after partner approval — the system first checks read-only scope, account ownership and the identity chain; client uploads are reviewed before posting and can be returned — the right to post stays with your firm
04之後月月自助Self-serve, month after month常駐入口+當場驗證碼登入,每月自動提醒待上傳的月結單;客戶亦可隨時一鍵解除連接——解除即停、貴所即知A standing portal with one-time codes; monthly reminders chase the statements for you. The client may also disconnect at any time — sync stops instantly and your firm is notified at once

會計師最常問的四件事The four questions accountants always ask

「出具的底稿,審計師認嗎?」"Will auditors accept the working papers?"

審計師認的從來不是軟件,是證據鏈。每個數字可追溯到來源檔案與批次,每條數據帶證據等級,終版文檔帶授權留痕——交出去的不是 App 截圖,而是完整的取數鏈路與底稿。What auditors accept is never the software — it's the evidence chain. Every figure traces to its source file and batch, every data point carries an evidence grade, and final documents carry the authorisation trail — what you hand over isn't an app screenshot, it's the full derivation.

「同事不懂 crypto,用得起來嗎?」"My staff don't know crypto — can they use it?"

介面說的是會計的語言——歸集、對帳、成本基礎、底稿,不是 DeFi 行話。日常同步全自動零確認,需要人的只有兩件事:核差異報警、按期出稿。20 分鐘演示就是完整的上手路徑。The interface speaks accounting, not DeFi jargon — aggregation, reconciliation, cost basis, working papers. Daily syncing runs itself; people are needed for exactly two things: reviewing difference alerts and issuing period-end documents. The 20-minute demo is the entire learning curve.

「客戶只給 Excel 怎麼辦?」"What if the client only gives us Excel?"

照收。對帳單導入是一等公民:檔案雜湊去重、區間重疊比對先預覽後入賬、批次可整體回滾。底稿將該來源標注為「客戶自報」;日後補只讀 API 即升級為「獨立獲取」——證據等級的差別,審計師都懂。We take it. Statement import is a first-class citizen: file-hash dedup, overlap preview before posting, whole-batch rollback. The working papers tag that source as "client-reported"; add a read-only API later and it upgrades to "independently obtained" — a distinction every auditor understands.

「算錯了誰負責?」"Who is responsible if a number is wrong?"

分兩層。計算對不對,是我們的責任:口徑公開、每一步可攤開複算,底稿不是黑箱;若引擎出錯,版本快照能精確定位受影響的客戶與期間,修正重出、舊版留檔。判斷對不對,永遠由貴所定奪:分錄草稿過不過賬、口徑適不適用,是專業的事。權責分明,才談得上追責。Two layers. Whether the calculation is right is on us: the methodology is published, every step can be laid out and re-computed — working papers are not a black box. If the engine errs, version snapshots pinpoint the affected clients and periods, corrected papers are reissued, prior versions stay on file. Whether the judgement is right is always your firm's call: whether a draft entry posts, and whether a treatment applies, is professional territory. Clear responsibilities are what make accountability real.
