Fees and estimate factors

Starting ranges for subscription billing audits, plus the factors that move a fixed fee up or down.

Full subscription billing audit

From HK$48,000

Fixed fee once we know active subscriber count and review period. Mid-size books (roughly 500–2,000 active subscriptions, 12-month period) commonly land between HK$48,000 and HK$95,000.

Recurring invoice reconciliation

From HK$28,000

Priced by monthly invoice volume and how many billing sources must be joined. Clean single-source exports finish at the lower end.

Contract-to-charge verification

From HK$22,000

Driven by the size of the contract pack and the number of distinct plan or discount schedules in force.

Pre-diligence billing review

Quote-based

Scoped to your diligence timetable, data-room needs, and whether adviser briefings are required. We confirm a fixed fee before fieldwork starts.

What changes the fee

  • Subscriber count and period length — More lines and longer windows mean more testing time.
  • Export quality — Fragmented CSVs, missing subscriber IDs, or paper-only invoices add days.
  • Amendment volume — Heavy mid-period discounting increases mapping effort.
  • On-site needs — Walkthroughs outside Hong Kong Island / Kowloon / New Territories travel bands are quoted separately.
  • Rush timing — Compressed diligence windows may require a priority schedule surcharge, disclosed before you accept.

How payment works

We invoice 50% to begin and 50% on delivery of the discrepancy register or findings memo. Fees are informational on this page; no payment is taken online. For a number tied to your books, send a short brief.
