Financial documents and calculator prepared for an audit review

InnoSoft Systems

Subscription billing audit for recurring revenue teams — invoice sampling, renewal leakage checks, and written findings you can take into close or a board packet.

Flagship engagement

A billing audit that starts with your contracts, not your dashboards

Recurring revenue teams ask us to prove that what customers were charged matches what the order forms and plan catalogs promised. We recalculate samples by hand, rate severity, and leave a remediation sequence your finance and ops leads can own.

Subscription Billing Audit

Cohort definition, document intake, sampling across plan types, manual recalculation, findings memo, and a walkthrough in Taipei or remote. Typical duration: three to five weeks after complete intake.

What finance leads take away

“They pulled a sample that included our quiet annual plans, not only the loud monthly ones. Two proration errors we had waved through for months showed up with the exact invoice numbers attached.”

Mei-Ling Chen — Revenue operations lead, Taipei SaaS publisher (The document request list felt long at first, though once we had the exports ready the fieldwork moved quickly.)

“Our renewal leakage review traced failed card retries that never reached a human queue. We recovered a cluster of reinstatements in the following billing cycle after their walkthrough.”

Daniel Wu — Finance manager, New Taipei subscription education firm
