A dedicated developer is a monthly capacity commitment, not a fixed project. It works when you have a continuous backlog, a technical lead who can set priorities and enough work to keep the person productive. Without those three things, a fixed-scope project or a small retainer is usually cheaper.
Key takeaways
- Buy capacity only when you can keep it busy.
- Put a named developer, a backup and a notice period in the contract.
- Manage the backlog weekly; do not wait for a monthly report.
- Keep code, accounts and documentation in your control.
What you are buying
You are buying reserved time and continuity. The developer joins your process, attends your planning, and works through your priorities. The vendor may add project management and QA, but you still own the product decisions. A dedicated model is a poor fit for a one-off website with a fixed launch date; it is a good fit for a product with a roadmap that changes.
| Model | Commitment | Best fit | Main risk |
|---|---|---|---|
| Freelancer project | Fixed scope and price | A bounded build | Change requests |
| Retainer | Monthly hours | Maintenance and small improvements | Unused time |
| Dedicated developer | Monthly capacity | Continuous product work | Idle capacity |
| In-house hire | Employment | Long-term core capability | Hiring and management overhead |
The monthly cost formula
A dedicated developer at £6,000/month for 12 months is £72,000 before VAT. Add management, review and tooling. Compare that with the value of the roadmap you can actually deliver: if you only have six weeks of work, a project contract is usually cheaper.
How to make it work
- Write a rolling 90-day roadmap. Keep the next two weeks detailed and the rest directional.
- Hold a weekly planning session. Agree the top three outcomes and what will be dropped.
- Review small increments. A weekly demo catches misalignment earlier than a monthly report.
- Track flow. Cycle time, blocked work and rework are more useful than hours logged.
- Review the model quarterly. If the backlog is empty or the work is repetitive, change the shape.
Contract terms to insist on
- A named developer, a named backup and a substitution process.
- A minimum term, notice period and a clear exit/handover.
- IP assignment and confidentiality.
- Repository, cloud and deployment access in your accounts.
- A response-time agreement for urgent production issues.
Market checks for the UK
Recurring capacity needs a clear exit, notice period and IP assignment, not just a monthly price.
| Area | What to confirm | Why it matters |
|---|---|---|
| Contracting entity | Which legal entity signs and who employs the developer | Enforcement and accountability |
| Tax and status | How VAT and IR35 / off-payroll working rules apply | A quote can change after tax |
| Data protection | How UK GDPR and the Data Protection Act 2018 affect customer and employee data | Cross-border transfers and notices |
| Currency and payment | The invoice currency (£), expenses and payment terms | Avoid a hidden exchange or cash-flow cost |
| Disputes | Governing law, jurisdiction and escalation path | A cheap contract is expensive if it cannot be enforced |
| Communication | Overlap hours, written updates and a named decision-maker | Time-zone drift is a delivery risk |
- Ask for the legal name and registration of the entity that will invoice you.
- Put the tax treatment and expenses in the contract, not only in the proposal.
- Confirm who owns the code, design files and third-party licences.
- Agree how access is removed when the engagement ends.
Frequently asked questions
A dedicated developer reserves recurring capacity for you, usually on a monthly basis. A freelancer is often hired for a bounded project. Dedicated works when you have a continuous backlog and can manage priorities; it is a poor fit when the work is a one-off build.
Three months is a common starting point because the first month is onboarding. A one-month trial is reasonable if it has a clear deliverable and an exit clause. Avoid a twelve-month commitment before you have seen how the developer works.
You do, or a technical lead on your side does. The vendor may provide project management, but you should own the backlog, priorities and acceptance. If nobody on your side can review the work, a dedicated model becomes an expensive black box.
Put continuity in the contract: named backup, documentation, overlap during holidays, notice period and access to the code. A dedicated developer should not be a single point of failure.
