The live product

Who it’s for
Small installation and service companies in the Netherlands whose work is built around recurring maintenance — the kind of business where the customer relationship continues long after the first job. B2B only.
How it works
Add or import your customers
Start from scratch or import an existing customer file, then add the installations that belong to each customer, including details and photos.
Set a maintenance interval
Per installation you set how often maintenance is due. ServiceSeintje calculates the next maintenance date from that interval.
See who is due
One overview shows what is overdue and what is coming up, so nothing quietly slips past its date.
Register the work
You decide when to contact a customer. After completed maintenance you record it — including contact moments — and the next date is recalculated.
What it does
- Customers and installations in one place
- Installation details stored per installation
- Maintenance interval with an automatic next maintenance date
- Overview of overdue and upcoming maintenance
- Completed maintenance recorded, next date recalculated
- Import an existing customer base
- Photos saved with installations
- Contact moments registered
- Works on laptop and phone
You stay in control of contact
ServiceSeintje signals which customers are due. It does not send emails to your customers automatically — the business decides when and how to reach out.
