Custom Internal Business Systems
The bespoke software your operations actually need.
Off-the-shelf SaaS fits 80% of standard cases. The remaining 20% — your specific operating model — is where teams waste hours every week on workarounds, spreadsheets, and manual data entry. Custom internal tools replace that drag with software designed around exactly how your business runs.
The pain points we keep hearing
- Spreadsheets running the business. 47 macros, 3 people who understand them, crashes when row count grows, no version control. Working but fragile.
- SaaS sprawl. 8 SaaS products, £2,500/month total, none of them talk to each other. Custom system could replace 3-4 of them and integrate the rest.
- "Just a quick app" never gets built. Internal request goes to a developer's side project, never finishes. Operations work around it forever.
- Audit trail nightmare. Compliance asks "who changed this customer's tier on 12 March?" Nobody can answer. No audit log exists.
What we typically build
Operations dashboards
Real-time view of your operational data — pipeline, inventory, customer ops, support queue — drawing from all your sources into one screen.
Custom workflow tools
Forms, approval flows, document generation, scheduling, dispatch — fitted to exactly how your team works. Not a generic project-management tool.
Internal admin / back-office apps
For customer success, finance, ops — the data-entry and lookup work that nobody wants to do, made fast and audit-logged.
Integration layers
The "glue" between your SaaS tools and your custom processes. Replaces brittle Zapier chains with proper engineered services.

Frequently asked questions
How long until live?
Single internal tool: 4-6 weeks. Multi-team platform: 8-12 weeks. Larger system: 12-16 weeks. Always with weekly demos so you see progress, not a black-box phase.
Will internal devs be able to maintain it?
Yes — we use mainstream stacks (TypeScript / Next.js / Postgres) any modern dev can pick up. Full docs, runbook, training session at handover.
What about authentication / access control?
Role-based access from day one. SSO support (Google Workspace, Microsoft 365, Okta). Audit log of every meaningful action.
Where does the data live?
Your choice. Default Postgres on Neon / Supabase / Vercel. Can deploy to your AWS / Azure / GCP. UK / EU regions available. Backups daily, point-in-time recovery.
Can it integrate with our existing software?
Almost always. Modern SaaS has APIs we use. Legacy systems we reach via screen-scraping, RPA, or CSV-bridge as last resort.
What if we want to extend it later?
You own the code. Pick up extension yourself, hire any modern web dev, or buy our retainer (£150–£600/month) for ongoing changes.
