Prevention process that stops surprise invoices

Step 1: Write scope in plain English
Create a short list of what is included and what is excluded. Make sureprojects are defined clearly.

Step 2: Require tickets for every request
Route all requests through one ticketing front door. This creates a record ofthe request, the owner, and the outcome.

Step 3: Add an approval gate for out-of-scopework
If a request is out of scope, pause and get approval. Approval should includeprice, timeline, and what is changing.

Step 4: Separate operations from projects
Monthly operations work is ongoing support. Projects are one-time changes andshould be quoted separately.

Step 5: Clarify vendor coordination expectations
Define who opens vendor cases and who owns escalation. Vendor blame loops oftencreate extra hours and repeat work.

Step 6: Document what changed and why
Require closeout notes that state what changed and what will prevent repeats.Documentation reduces future billable rework.

Step 7: Review trends monthly
Look for repeat issues, recurring projects, and frequent vendor incidents.Trends tell you where standards are missing.
