The live product

Who it’s for
Freelancers and small businesses in the Netherlands with recurring maintenance or periodic service — the kind of work where the customer comes back again after the first job. B2B only.
Examples of businesses using it
- Air conditioning & heat pumps
- Pool servicing
- Garden maintenance
- Alarm & security
- Installation technology
- Periodic inspections
- Other businesses that see customers again periodically
How it works
Add or import your customers
Start from scratch or import an existing customer file, then add the installations and service items that belong to each customer, including details and photos.
Set a maintenance interval
Per item you set how often maintenance or service is due. ServiceSeintje calculates the next date from that interval.
See who is due
One overview shows what is overdue and what is coming up, so no customer quietly slips past their date.
Register the work
Contact the customer, record the contact moment and log the completed maintenance or service. The next date is then calculated again.
One overview of who is due
The dashboard shows overdue and upcoming customers side by side, so you can plan your week without digging through spreadsheets or a calendar.

What it does
- Customers, installations and service items in one place
- Relevant details and photos stored per item
- Maintenance interval with an automatic next date
- Dashboard of overdue and upcoming customers
- Contact moments and completed work recorded
- Next date recalculated after completed work
- Import an existing customer base
- Works on laptop and phone
- Deliberately not a heavy CRM or ERP system

Reach out yourself, or let Pro do it
With ServiceSeintje Basis you decide when and how you contact a customer. ServiceSeintje Pro can send the reminder by email for you, with at most one follow-up if there is no response — and automation stops as soon as the customer replies or the work is registered.
Trial and packages
14 days free with all Pro features available, no payment details required and no package choice up front. After the trial you choose Basis or Pro, monthly or yearly. All prices are excl. VAT, B2B only.
