SlimKlantPortaal.nl
From market feedback to a working product, built by demand from Joost, Denise and Sietse
The story
Before
Three professionals with the same frustration: Joost wants to request energy labels faster, Denise looks for secure customer communication, Sietse wants to automate payments after structural calculations.
Obstacle
Everyone works differently. Joost has a different flow than Sietse. Every existing system forces one way. They want flexibility, not rigid software.
Insight
Don't build a solution for one client. Build a platform that supports multiple workflows. Make it a Seven Technologies product that evolves with user feedback.
After
14 days later: working MVP. Joost, Denise and Sietse test and give feedback. Their input shapes the product now called SlimKlantPortaal.nl.
The first 14 days
From concept to working prototype.
Kickoff and customer-intake flow mapping
We map the entire intake journey. From first contact to complete dossier. Which documents? In what order? What always goes wrong?
Wireframes and user journey
Screens for customer and administrator. How does it feel for someone seeing this for the first time? We keep it simple.
Database architecture
Clients, dossiers, documents, notifications. Everything structured and secured. Privacy by design from line one.
Auth and portal setup
Login system with magic links. No passwords, no hassle. Every customer gets their own secure space.
Document upload and storage
Drag-and-drop, file type validation, encryption. Files are securely stored and directly linked to the right dossier.
Admin dashboard MVP
The team now sees all dossiers in one overview. Status tracking: new, incomplete, complete. No more Excel needed.
First demo with team
We show what's there. The team tests the flow, clicks around, gives feedback. We note everything that can be improved.
Notification system
Automatic emails on new documents, incomplete dossiers, deadlines. For client and administrator alike.
Custom forms builder
The team can now make forms themselves. Add fields, make required, add logic. No developer needed for every change.
Status tracking and workflow
Dossiers now go through statuses. From intake to completed. Team members get tasks assigned. Nothing falls through the cracks anymore.
Client-side interface polish
Customers must like it. Clear instructions, progress bar, confirmations. No doubt about what still needs to happen.
Security layer and encryption
All uploads encrypted. 2FA option. Audit logs of who viewed what when. Privacy-proof.
Integration with existing tools
Webhook to their CRM. Automatic Slack notifications. Email forwards. The portal talks to the rest of their stack.
Training and go-live
The team learns how to manage the system. We go live with the first real customers. It runs.
1-3 months later
Roadmap: from MVP to multi-tenant platform
The product is only 1 month old. Joost, Denise and Sietse use it daily and constantly give feedback. The coming months: perfecting their specific workflows, adding new users from their networks, and preparing the platform for scaling. Every feature is tested in practice before being generally available.
1 year later
Vision: the customer portal for freelancers in the Netherlands
In a year we want SlimKlantPortaal.nl to be THE platform for freelancers and small agencies that want to communicate professionally with customers. Multi-tenant, white-label option, API for connections. We build it step by step, tested by real users. No big bang launch, but organic growth based on word-of-mouth and proven value.
"I wanted secure customer communication and document management. After 14 days I had a working system. My feedback is taken seriously and processed directly. This feels like our product."
