Choosing the wrong development partner is expensive — missed deadlines, poor code, and products that don't scale. Use this checklist before you sign.
12-point agency checklist
- Relevant case studies in your industry or tech stack
- Senior engineers on your project (not only juniors)
- Fixed-price or clear milestone billing
- NDA and IP transfer in writing
- Weekly demos and transparent communication
- Post-launch support and warranty terms
- References or verifiable reviews
- Understanding of your business goals, not just tickets
Red flags
- No questions about your users or revenue model
- Unrealistically low estimates with no scope document
- No code ownership clause
- Poor English or timezone mismatch without overlap plan
