Overview

From prototype to a SaaS product UK customers will pay for

How working with us from Karachi fits the UK

  • Karachi is 4 to 5 hours ahead of the UK, so we overlap your whole morning and early afternoon.
  • Fixed quotes in GBP or USD, agreed before work starts.
  • Weekly demos on a staging environment and a shared channel for everything else.
  • You own 100% of the code, accounts and infrastructure.

Many UK founders now arrive with a prototype built in Lovable, Bolt or another AI tool. It proves the idea, but it is not ready for paying customers: permissions, billing, security and edge cases are usually missing. Our Production Sprint fixes exactly that, from $2,000 over two to four weeks.

If you are starting fresh, we build the MVP properly from day one: multi-tenant data model, roles and permissions, subscription billing, admin tools and a clean, fast interface.

We did this for Seatsy, a UK product we took from an AI-generated MVP to a polished, production-ready web and mobile platform.

What UK SaaS buyers expect

  • UK GDPR and data processing

    B2B customers will ask where data is stored, who can access it and how deletion works. We build those controls in and document them for your data processing agreement.

  • Security questionnaires

    Larger UK customers send security questionnaires before they buy. We build with access control, audit logs, encryption and least privilege so you can answer them honestly.

  • Billing in GBP

    Stripe subscriptions in GBP with VAT handling, invoices, trials, plan changes and failed payment recovery, plus Direct Debit through GoCardless where B2B customers prefer it.

  • Accessibility

    Interfaces built to WCAG 2.2 AA, which public sector and enterprise buyers increasingly require.
