Fees & estimate factors
Audit fees follow the period under review, subscriber volume, and how readily your billing application can export usable files — not a software-style monthly plan.
Starting ranges
| Engagement | Typical basis | Starting indication (THB) |
|---|---|---|
| Subscription billing financial audit | Quote after scoping | From 180,000 for a single entity and one fiscal year |
| Revenue cut-off review | Fixed quote per close | From 45,000 for a two-week cut-off window |
| Processor settlement reconciliation | Day rate or fixed block | Day rate from 18,000; fixed blocks from 72,000 |
These figures are informational. Final quotes reflect your actual scope. No checkout or payment runs through this website.
What moves a quote up or down
- Number of active plans and currencies in the period
- Whether annual prepayments and usage overages both apply
- Cleanliness of exports (native CSV/API dumps versus reconstructed spreadsheets)
- On-site sessions in Phuket versus fully remote fieldwork
- Urgency ahead of a filing or diligence deadline
Deposits
Engagements above 100,000 THB usually require a 30% deposit to reserve the fieldwork window. The balance is invoiced on delivery of the draft findings pack. See our refund policy for how deposits and cancellations are handled.
What we do not sell
We do not offer monthly “monitoring subscriptions,” seat-based licences, or tiered Starter / Professional / Enterprise software packages. If you need ongoing close support after an audit, we can discuss a separate retainer for follow-up questions — still billed as professional time.
