Repair one agreed path
Bot buttons, Mini App handoff, order intake or an API call. Major rewrites, migrations and new features are quoted separately.
Keep the fix verifiable
Receive the change, regression checks, handover notes and 7 days of fixes for bugs related to the agreed repair.
A free fit check is not a production audit. If investigation is needed, the $79 diagnostic delivers written findings and is credited toward implementation booked within 14 days. We agree the price and timing before work starts.
