Web apps & client portals
Client portals, internal tools and apps – in the browser, on the home screen or in the app store. With login, documents, status and push notifications, so nobody has to call to ask.

How it works
This is how a client works with your portal – and your team in the background.
Your client
By link, code or password – in the browser or as an app on the home screen. Everyone sees only their own data.
Your client
Documents by phone photo, a checklist shows what is missing. The status of the case is visible at any time.
Your team
Queries, approvals and documents stay attached to the case. The client gets a push notification as soon as something happens.
You
Status questions answer themselves, documents arrive complete, and everything is logged and traceable.
Scope & prices
Each tier builds on the previous one. We define the exact scope after the prototype – then a fixed price applies.

Buy or rent
The same software, two ways: pay once and own it – or rent monthly and start right away.
Buy
Pay once, own it for good.
Rent€0 upfront
A monthly rate instead of a one-off price.
Can be added to any tier – the fixed price is set after the prototype.
Sample calculation
Each query is small. Added up, it is half a job.
Paid off after
around 7 months
Not included: documents that arrive complete, and clients who check for themselves at ten in the evening instead of calling in the morning.
Sample calculation with assumed values – not a promise. Plug in your own numbers; we run them together in the first call.
When it isn't worth it
If you have few clients and every case is different, a portal hardly helps – then the personal conversation is your advantage. And if an app is only wanted because »you ought to have one«, we advise against it.
In use
Wherever clients, tenants or customers ask regularly, a portal pays off fastest.

We start with a pilot group and roll out as soon as it holds up in daily use.
Day 1
We walk through a typical case: who asks what, who delivers what, where does it snag?
Day 7
You click through your portal as a client and as a staff member. Then the fixed price is set.
Weeks 2–6
Login, documents, status, then workflows. Each stage is usable, and you see progress every one to two weeks.
From week 6
Start with ten clients, adjust from daily use, then everyone else.
