Custom Software Development: When to Hire a Freelancer (Not an Agency)
Custom software built for your business — agency vs freelance developer, milestone contracts, escrow, and how to hire a senior full-stack engineer who ships without account manager overhead.
By Raymond Tse · Full-stack & Web3 engineer · Abuja, Nigeria
You searched "custom software development" because off-the-shelf tools do not fit your operations. You need something built around how your business actually works — not another workaround. The question is: agency, in-house hire, or freelance developer?
Agency vs freelance vs in-house
- Agency ($30k–$100k+): account managers, slow feedback loops, juniors on your project.
- In-house ($80k–$150k/yr salary): best for 12+ months continuous work post-PMF.
- Senior freelance ($6k–$25k per project): direct communication, same person every call, ships in weeks.
How to hire a freelance developer safely
- Define scope in writing — features, timeline, acceptance criteria.
- Use Upwork escrow or milestone contract — fund phase by phase.
- Check live products — not PDF portfolios.
- Paid trial before main contract.
- Weekly demos — working software, not slide decks.
Custom software I have shipped
- BetJuju — consumer sports platform, betjuju.ng.
- PayParrot — fintech + AI payments platform.
- AdhereWell — health adherence for 4K+ patients.
- A4T Power CRM — renewable energy client at $60M MoU scale.

No workarounds. No compromises. Software built to run your business — that is what custom development should mean.
