Change control in writing

Cheaper than a local build

Frequently asked questions
1. Why is there a range instead of one price?
The spread comes from user roles, integrations and compliance. A single-role internal tool sits at the bottom of the band; a multi-role platform with ERP sync and audit requirements sits at the top. Discovery closes the gap to one number.
2. What does a dedicated developer cost per month?
A mid-level engineer, a senior engineer and a shared tech lead with QA is the usual first squad, billed monthly in GBP with 30 days notice. Ask for the current rate card — it is one page and it includes overlap hours.
3. How much timezone overlap do we get with your team in United Kingdom?
Four to six hours of daily overlap with United Kingdom business hours as standard, including a written standup before your morning and a live call whenever you need one. Escalations are answered within two hours during Mon-Fri, 9am-6pm GMT.
4. How does a dedicated developer engagement actually work?
You get named engineers, not a rotating pool. We agree the squad, run a two-week onboarding sprint against your codebase, and bill monthly per engineer with a 30-day notice period. You approve every hire and can swap a profile within the first two weeks.
5. What does the offshore collaboration workflow look like?
Your board stays the source of truth — Jira, Linear or Azure DevOps. We work in your repo with pull-request reviews, ship to a staging URL every Friday, and send a one-page weekly report covering what shipped, what slipped and what we need from you.
