Why UK buyers choose us

A remote-first, US-headquartered senior team building bespoke software for UK businesses — GBP invoicing, a UK working-hours overlap and UK-GDPR-aware delivery, with the code yours from day one.

  • Remote-first senior engineers with a UK business-hours overlap window for stand-ups, demos and incident response
  • Invoiced in GBP (£) against a clear fixed-bid scope, so there are no surprise currency conversions on your purchase order
  • Delivery built to be UK-GDPR and ICO-aware: lawful-basis mapping, data-minimisation and a documented data-processing trail
  • Contracts run under a mutually agreed governing law, with a mutual NDA and the GitHub repository transferred to your organisation

We deliver with UK-GDPR and ICO expectations in mind — lawful-basis mapping, data-minimisation, subject-access readiness and a documented processing trail. We build to the controls your DPO or auditor specifies (we are not a law firm), and can scope UK or EU data residency where a workload requires it.

What this includes

Deliverables, line by line.

  • Two-week paid discovery with a fixed-bid proposal at the end
  • Role and permission model mapped to your account types
  • Authentication and account provisioning via Auth.js or Clerk
  • Customer portal: orders, invoices, documents, and support tickets
  • Vendor or supplier portal scoped to your procurement flow
  • Dealer or partner portal with tier-based pricing and protected catalogues
  • Document storage on S3-compatible object storage with access controls
  • Live integration to QuickBooks or NetSuite for invoice and order data
  • Admin console for your team to manage accounts, tiers, and content
  • Production deployment with staging, plus source in your GitHub org
Process

How an engagement runs.

  1. 01

    Discovery

    Two weeks, paid. We map every account type that touches the portal, the actions each one needs, and where the data lives today. You leave with wireframes, a permission matrix, and a fixed-bid proposal.

  2. 02

    Auth and data foundation

    Sprint one stands up authentication, the role model, and the connection to your ERP or accounting system. Reading real invoices and orders into a staging portal is the milestone, not a mockup.

  3. 03

    Portal build

    Two-week sprints build out the screens each account type uses, with a Loom demo every Friday and a staging deploy you can hand to a friendly customer to pressure-test.

  4. 04

    Integration hardening

    We make the sync two-way where it needs to be, handle the failure cases when your ERP is down or returns garbage, and add audit logging so you can answer who saw and did what.

  5. 05

    Rollout

    We launch to a pilot group of accounts, watch the support load, and fix the rough edges before opening it to everyone. A 60-day stability window follows where we sit on call for issues.
