Client Challenge
Where they were stuck
- Teams pay for 15 SaaS tools and still copy-paste between them.
- No single tool matches the actual business process.
- Off-the-shelf integrations are shallow and brittle.

Project Overview
The engagement
A concept build showing how a bespoke web app can stitch together a company's existing SaaS stack — CRM, accounting, ops, comms — into a single workflow instead of a browser-tab tax.
Our Solution
What we built
- Custom UI built around the real workflow, not vendor menus.
- Deep API integrations with retries, rate limits and observability.
- Role-based access with audit trails.
- n8n backbone for evolving automations without redeploys.

Results
The outcome they feel every day
Hours back per person per day
The team works in one place, at the speed of the business.
Fewer errors
Automations enforce the rules that humans quietly forget.
Strategic leverage
The internal app becomes a competitive advantage, not a cost centre.
"The moment a growing business needs a real internal app, this is exactly what it should look like."
