A full-stack developer is a good fit when you can describe the outcome and give someone enough context to own it. In the UK, compare the delivery model, the total cost and the handover terms before you compare day rates.
Key takeaways
- Write a one-page outcome brief before you shortlist.
- Compare total cost: estimate × rate + contingency + tax + handover.
- Test judgement with a small, paid work sample.
- Keep code, domains, cloud accounts and analytics in your name.
What you are actually buying
One person who can take a feature from database to interface. The best fit is a product with a clear backlog and enough variety to keep one capable generalist busy. The main risk is that a generalist can be shallow in security, infrastructure or mobile unless you check depth. A good supplier will talk about the boundary, the acceptance test and what happens after launch, not just the technology.
Delivery models compared
| Model | You get | Best fit | Main risk |
|---|---|---|---|
| Freelancer | Direct access to one person | Bounded, specialist work | Single point of failure |
| Boutique agency | Design, engineering and QA | A launch with several disciplines | Overhead and unclear who codes |
| Dedicated developer | Monthly capacity | A continuous roadmap | Idle capacity |
| Offshore team | Larger delivery capacity | A stable backlog and strong process | Coordination and IP risk |
The cost formula
Use a simple model: realistic days × day rate, plus 15–25% contingency, VAT, launch and handover. For example, £500/day × 25 days = £12,500; add a 20% contingency (£2,500) for discovery, revisions and handover. Replace the rate with your actual quotes. The point is not the example rate; it is that every quote should expose the same inputs so you can compare them.
The one-page brief
- Outcome: what changes for the user or the business.
- Users: who uses it, on what device and how often.
- Must-have workflows: the few paths that must work on day one.
- Integrations: payments, CRM, ERP, email, analytics or identity.
- Constraints: deadline, budget band, hosting, compliance and existing systems.
- Acceptance: how you will know the work is finished.
How to vet
- Ask for relevant evidence. A project with a similar constraint, not just a similar industry.
- Run a paid work sample. A small task with a real deadline and a review.
- Check communication. A short written update each week is a better predictor than a confident interview.
- Check the handover. Repository access, environment variables, documentation and deployment.
- Read the contract. IP, payment, acceptance, change control, data protection and exit.
Contract terms that protect you
| Term | What to require |
|---|---|
| IP | Assignment on payment, including design files and third-party licences |
| Payment | Milestones tied to verifiable deliverables; final payment on acceptance |
| Change control | Written requests with cost and schedule impact |
| Data | Confidentiality, data-processing terms and subcontractor disclosure |
| Security | Access controls, dependency updates and incident notification |
| Exit | Notice, handover, credentials and a support period |
A 30-day hiring plan
- Days 1–3. Write the outcome, budget band and must-have workflows.
- Days 4–10. Shortlist three suppliers and ask the same questions.
- Days 11–17. Run a paid work sample or a paid discovery session.
- Days 18–24. Check references, contract terms and security.
- Days 25–30. Sign, set up access and agree the first two-week slice.
Red flags
- A fixed price with no scope or acceptance criteria.
- No named person and no explanation of who does the work.
- No IP assignment or data-processing terms.
- A portfolio with logos but no outcomes.
- Reluctance to give repository or account access.
Market checks for the UK
The cheapest quote is not comparable until the currency, tax, expenses and payment terms are explicit.
| 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
Years are a weak signal on their own. Look for three or four projects where they owned a feature from data model to interface, and ask what broke in production. A capable developer with three strong years can outperform a ten-year generalist who has never owned an outcome.
Use one full-stack developer when the work is small, the interfaces are clear and speed matters. Split into frontend and backend specialists when the product has complex security, high traffic, a native app or a large design system. The coordination cost of two specialists is real, but so is the risk of one person being shallow in a critical area.
A working environment, access to the codebase and a small, user-visible deliverable with a review. The first month is a test of communication and judgement as much as coding. If you only see commits and no explanation, ask for a short written update every week.
Use a written contract that assigns all work product and IP to your company on payment, requires the supplier to disclose third-party and open-source components, and covers confidential information. For cross-border work, confirm the governing law and who can enforce the assignment.
