[01] Local context

Why Grantham businesses pick custom over off-the-shelf.

Most Grantham custom-app builds replace a process that lives across spreadsheets, WhatsApp groups, and SaaS tools that almost work. Customer portals, multi-step calculators, booking systems, account dashboards — anything where end-users interact directly with your business.

Most ship in 2–6 weeks. Branded to your business, source-code-yours, hosted on your own Vercel/Netlify account. Average Grantham build: £900–£6,000. We have shipped useful custom apps at £400 (single-purpose calculators) and at £8k (full SaaS-grade web apps) for clients in the wider East Midlands.

Free 30-minute discovery call to figure out what is possible and what it would cost. Fixed quote in writing within 48 hours.
