What actually goes wrong with agency overflow work
Agencies don't fail because they can't find developers. They fail because the developer they found can't be trusted with the client's name on the line. The risks are specific:
- The quality lottery. A contractor ships something that demos fine, then your team inherits untyped spaghetti, no tests, and zero docs. You eat the cleanup cost — and it's invisible until the project is already late.
- The management tax. Offshore teams in a far timezone need daily syncs, written specs for everything, and re-explanation when something slips. The hours your PM spends managing them cancel out the savings.
- Disappearing acts. The contractor takes a bigger gig mid-sprint, goes quiet for three days, and your client deadline doesn't move.
- White-label leakage. Some contractors try to contact your client directly or stamp their name on the deliverable. That's a relationship you can't get back.
The core problem: you're not buying code, you're buying predictable delivery against a date you've already promised someone else.
