Freelance Subcontracting: Vetting and Paying Other Developers Without the Drama

You land a project that's slightly bigger than you can handle alone, so you bring in another developer to cover a slice of the work. Sounds straightforward. Then the deadline arrives, the deliverable is half-finished, and you're the one on the hook with your client because you're the one who signed the contract. Subcontracting is one of the fastest ways to scale up — and one of the fastest ways to damage a reputation you spent years building if you do it carelessly.

This guide walks you through the practical steps: how to find and evaluate candidates quickly, what to put in writing before a single line of code is written, how to structure payments so nobody ends up resentful, and how to keep your client relationship clean throughout.

What you'll learn

• How to assess a subcontractor's real skill level before committing
• What your written agreement must cover to protect both sides
• How to structure milestone-based payments that keep work moving
• How to handle your client relationship when you're delegating work
• What to do when things go wrong mid-project

Why Subcontracting Is Different from Hiring

When you subcontract, you remain the primary contractor. Your name is on the deliverable, and your client doesn't care that someone else wrote part of it. That asymmetry of accountability shapes every decision you make about who you bring in and on what terms.

This is not the same as referring a client to another freelancer or co-bidding on a project. You are taking responsibility for another person's output. That means your vetting standards need to be at least as high as they would be if you were hiring the person to work directly for you.

Finding Candidates Worth Vetting

The best subcontractors usually come from your existing network. Someone you've worked alongside on a previous project, a former colleague, or a developer you've reviewed code from in an open source context already has a track record you can actually see. Cold sourcing from job boards is a last resort, not a starting point.

If you do go broader, look for candidates with public work you can inspect: GitHub repositories with consistent commit history, contributions to libraries you recognize, or portfolios that show projects close to what you need. A long list of claimed skills without evidence is a red flag. Anyone can write
