What access do you need?
A copy of your resources and database is enough to start. I work on a staging copy and never need live credentials for the audit.
Do you review escrowed resources?
I can profile them and see how they behave, but escrowed code cannot be read or changed. You will know exactly which ones cause problems.
Can you guarantee there are no exploits left?
No honest auditor can. I close every path I find and leave you a list of what to watch.
How are payments handled?
Payments go through Tebex, the official payment partner for FiveM. Projects start with a 50% deposit; the rest is paid on delivery. Audits are paid upfront.
