Choosing a software development partner is one of the most consequential decisions a UK SME makes. The right partner delivers software that works, on time and on budget, with ongoing support. The wrong partner delivers delays, cost overruns, and software that does not meet your needs. The difference comes down to four criteria: proven experience, a clear delivery process, transparent pricing, and post-launch support.
We help UK businesses evaluate whether we are the right partner for their project. This means being honest about what we do well and what we do not. This guide gives you the criteria to evaluate any development partner, including us.
What Experience Should You Look For?
The most reliable predictor of future performance is past work on similar projects. A partner who has built five bespoke CRMs will deliver your CRM faster and better than one building their first. Look for:
- Relevant project types: Have they built what you need before? A web portal is different from a mobile app, which is different from an API integration.
- Similar business size: A partner used to working with UK SMEs understands your constraints better than one used to enterprise clients with 500,000 budgets.
- Industry familiarity: If your industry has specific compliance or workflow requirements (healthcare, financial services, legal), experience in that sector matters.
- Case studies with outcomes: Not just screenshots, but what the software achieved. Did it reduce costs? Improve efficiency? Replace a SaaS platform?
Ask to see two or three relevant case studies and, if possible, speak to a past client. A reputable partner will facilitate this. See our about page for our experience and approach.
What Delivery Process Should They Follow?
A clear delivery process is the difference between a project that finishes on time and one that drifts. Look for a partner who can explain their process clearly:
- Discovery: They should start by understanding your requirements before quoting. A partner who quotes before asking questions is guessing.
- Design: Wireframes, database design, and technical architecture before development starts. You should approve the design before code is written.
- Phased development: Delivery in iterations, with working software at the end of each phase. Not a six-month wait followed by a big reveal.
- Testing: Automated tests, manual QA, and user acceptance testing. A partner who does not mention testing is cutting corners.
- Deployment: A clear plan for going live, including data migration, user training, and rollback options.
- Post-launch support: A defined support period and an ongoing maintenance agreement.
See our process page for how we approach delivery. A partner who cannot explain their process clearly is a risk.
How Should They Price Their Work?
Transparent pricing is essential. There are three common models, each appropriate for different situations:
- Fixed-scope: A defined deliverable with a fixed price and timeline. Best when requirements are clear. You get cost certainty. The risk is that any scope change requires a change request and potentially additional cost.
- Time and materials: You pay for actual time spent. Best when requirements will evolve. The risk is open-ended cost. Mitigate this with regular progress reports and a budget cap.
- Retainer: A monthly fee for a dedicated developer or team. Best for ongoing development. Provides flexibility and predictable monthly cost.
Whatever the model, you should receive:
- A clear breakdown of what is included
- Regular progress reports showing time spent and work completed
- A named project lead who is accountable for delivery
- No surprise costs without prior agreement
Beware of quotes that are significantly lower than others. A partner who underprices either does not understand the scope or plans to cut corners. See our guide on custom software costs to understand realistic pricing.
What Post-Launch Support Should They Offer?
Software is not finished at launch. It needs maintenance, updates, and occasional new features. A good partner offers:
- Warranty period: Free bug fixes for a defined period after launch, typically 30 to 90 days.
- Maintenance agreement: Ongoing maintenance covering security updates, dependency upgrades, and minor fixes. Typically 15 to 20 percent of build cost annually.
- Support response times: Defined response times for critical issues. A 24-hour response for critical bugs is standard.
- Hosting and monitoring: Either managed hosting or clear guidance on infrastructure setup and monitoring.
- Documentation: Technical documentation, user guides, and code comments so the software can be maintained by anyone.
A partner who delivers software and disappears is a liability. You need someone who will be there in six months when an external API changes or a security patch is needed.
What Are the Red Flags to Avoid?
These signals indicate a partner to avoid:
- Quoting before understanding requirements: A price without a discovery phase is a guess.
- No case studies or references: If they cannot show past work, they may not have any.
- No testing or QA process: Software without testing is defective by default.
- Unwillingness to sign a contract: A professional partner uses contracts that protect both parties.
- No mention of ongoing support: Software needs maintenance. A partner who does not mention this is not planning to be around.
- Pressure to start immediately: Good partners have pipelines. If they can start tomorrow, ask why.
- Vague about technology: They should be able to explain their technology choices and why they suit your project.
