Turn a complex requirement into a useful, maintainable experience.

Our approach

Define your website development requirements

Custom development often connects a website with another part of the business: a catalogue, CRM, customer account, booking system or operational workflow. We start by identifying which system owns the data and what should happen when information changes or a connection fails.

The technical choice follows the job. A static website, a small server endpoint and an authenticated application have different requirements. We recommend the least complicated approach that meets the agreed behaviour and can be operated responsibly.

Agree functional testing and acceptance criteria

A feature needs more than a description of the happy path. We agree inputs, permissions, outputs, exceptions and what a successful test looks like. That gives the business and developers the same definition of completion.

Document and maintain your website

Access, deployment, monitoring and ownership should be documented in proportion to the system. Dependencies and running costs belong in the scope. We can build around an existing platform where appropriate rather than assume every custom requirement needs a complete rewrite.

Discuss your target markets

Bird works from London and Essex with businesses serving nearby customers, the wider UK and international markets. We agree which of those audiences matters to this brief before recommending pages or campaigns. Contact the team to confirm meeting arrangements and bring the website, business priorities and any relevant constraints to the discussion.

BoundaryQuestion to agreeExample acceptance check
InputWhich system owns the source data?An approved change appears once in the expected destination
AccessWho may read or change it?An unauthorised user cannot retrieve another customer’s record
FailureWhat happens if the provider is unavailable?The user sees a useful state and a retry does not duplicate an action
OperationWho investigates and restores the connection?The handover identifies an owner and a reproducible check

Examples for scoping; specific controls depend on the application.

Frequently asked questions

Can you work on an existing website codebase?

We can review the stack, code access and the requested change before accepting a scope. Understanding dependencies, deployment and test coverage helps identify what can be delivered safely. An initial technical review may be needed.

What do you need before estimating development?

We need the problem, affected users, intended behaviour and important constraints. Existing designs, interfaces and examples can help. We then agree acceptance criteria and identify unknowns that require investigation before a firm estimate.

Do you build integrations?

Integrations can be scoped where a suitable interface and access are available. We define the data involved, authentication, ownership and failure handling. The proposal identifies both development work and any third-party service costs.

How will the work be tested?

Testing follows the feature’s actual requirements and risks. It can include automated checks and representative browser journeys, along with validation of errors and access controls. Acceptance criteria are agreed so completion is observable.

Who owns the code after delivery?

Ownership, repository access and licensing are set out in the agreement. Handover should include the information needed to operate and maintain the delivered work. Third-party components keep their applicable licences.

Do you provide support after launch?

Ongoing support can be agreed separately from the build. We distinguish fixing an issue in the delivered scope from new features or changed requirements. Responsibilities for monitoring, deployment and maintenance should be clear.

Define the next step

Discuss your project.

Share your website, the problem you want to solve and any constraints. We’ll discuss the fit, the evidence needed and a scope before work begins.
