How an engagement runs

Specification

Requirements are gathered and written down before anything is built. The specification is the shared reference for scope, cost and delivery.

Estimation

Cost and timeline are stated against the specification before work begins. Changes are discussed and priced, not absorbed silently.

Build and release

Work is delivered in increments and verified in production at each step.

Running

Monitoring, patching, backups and upgrades continue after delivery, with reporting in plain language.

Common questions

Who owns the software?

You do. Code and deliverables belong to the client on payment.

Can you take over an existing system?

Yes. We review the system, document its state, and take responsibility for it in stages.

How do engagements start?

With a written specification. Tell us what you need; scoping the work is where we begin.

Where are you based?

Teelsa Ltd is registered in England and Wales. Work is remote, with clients anywhere.

Do you work with our in-house team?

Yes. We slot alongside internal teams as readily as we run whole systems.
