Frequently asked questions
What a buyer should know.
What exactly do you compare?
Governing contracts, amendments and approved change records are compared with the condition represented in current billing for the selected recurring accounts.
Are you saying we have billing errors?
No. The review tests whether the records align and identifies potential contract-to-billing exceptions requiring management verification.
Is this an accounting audit?
No. It is a focused revenue-control review, not an accounting audit, legal opinion or assurance engagement.
Do we have to change software?
No. The review examines the available source records and current billing condition. It does not require a software change.
What if we already have internal controls?
The review can provide a focused, source-linked comparison for a defined account set. It does not replace management’s existing controls or decisions.
What happens if you flag something?
The item is documented with its source, comparison, confidence, missing evidence and a management verification action. Trellon Works does not change invoices or contact customers.
What does it cost?
$1,500 fixed for up to 20 recurring commercial customer accounts.
How long does it take?
7 business days after authorized complete intake.
What information would eventually be needed?
For the selected accounts, the review would generally require governing contracts, applicable amendments or approved change records, and current billing records. Please do not send those materials yet.
How would sensitive files be handled?
Before any contracts or invoices are requested, Trellon Works will confirm the next step and the appropriate data-handling process. This page does not represent a confidential-file intake system as active.
