Treasury OS
A unified multi-entity, multi-currency ledger with rule-based sweeping and automated cash-position reporting.
B2B SaaS · Headquartered in Hong Kong
The operating system for cross-border commerce.
BestNine unifies treasury, payments, trade documentation and counterparty intelligence into nine integrated modules — purpose-built for operators scaling across Greater China, ASEAN and the wider Asia-Pacific.
Nine modules
One platform. Nine moving parts that finally agree.
Every module shares a single ledger, identity model and audit log — so your treasury team, ops team and engineering team are reading from the same source of truth instead of stitching spreadsheets.

Cross-border Payments
Pay-out and collection rails across HKD, CNY, USD, SGD, JPY and MYR via tier-1 banking partners.

FX & Hedging
Live mid-market quotes, programmable forwards and policy-driven hedging that flows straight to your books.

Onboarding, sanctions screening, UBO mapping and ongoing monitoring against 200+ global watchlists.

Counterparty Intelligence
Risk scores, behavioural fingerprints and shipment histories on the buyers and suppliers in your pipeline.

Tax & Invoice Sync
Bidirectional sync with Xero, QuickBooks and Kingdee — VAT, GST and HK profits-tax aware.
M·08▦
Capital Flow Analytics
Cohort cash-flow, working-capital runway and entity-level P&L queries — answered in under three seconds.
M·09{}
API Workbench
REST + webhook surface for every primitive in the platform, with idempotency keys and signed payloads.
The platform
Built for operators, not just the CFO.
Finance, ops and engineering each get a workspace tuned to their work — backed by the same audit trail, the same approval rules and the same set of APIs underneath.
- 01One ledger across every module.
No more reconciliation between systems — every payment, FX trade and invoice posts to the same double-entry ledger automatically.
- 02Native APIs and webhooks.
Each primitive is callable from your stack with idempotency keys, signed webhooks and sandbox environments that mirror production behaviour.
- 03Granular roles & approvals.
Compose policies down to the entity, currency and counterparty level — with hardware-backed approval prompts where it matters.
- 04Audit-ready event log.
Every action is captured as an immutable event with the actor, payload diff and IP — exportable to your SIEM the moment auditors ask.

We assume the auditor is in the room. Every primitive in the platform produces a verifiable event, and every secret is held by a hardware-rooted key — so going through diligence stops being an annual fire-drill.
Hong Kong is our regulatory anchor. Client funds are held in segregated accounts at tier-1 partner banks, sensitive workloads run inside a hardware-backed enclave, and every release ships through a dual-control change pipeline. Penetration tests run quarterly against production-equivalent environments.
