Care scheduling

Connecting Nedap ONS to your HR and payroll system: employees in, hours and allowances out

Connecting Nedap ONS to the HR and payroll system means care staff come from HR into ONS with contract hours, team, expertise and collective agreement, and approved hours and irregular-hours allowance (ORT) go back to payroll. KoppelHet connects ONS with AFAS, HR2day, Visma Raet YouForce and Visma YouServe, including where Nedap provides no ready-made hours export.

What it is

In care, scheduling happens in Nedap ONS and the employee lives in the HR system. Care staff often have more than one employment, such as a permanent post and a relief contract, sometimes under different collective agreements. ONS calculates the irregular-hours allowance itself according to the agreement.

Nedap provides a ready-made hours export for ADP, AFAS and SDB, but not for YouForce or HR2day. The AFAS export also has to be imported by someone in AFAS. Without an integration ONS schedules on outdated contract hours, and hours move over as a file.

How the integration handles it

ONS always takes an employee as a whole and treats a missing contract or team as ended. The integration therefore sends all current contracts and teams with every change.
ONS identifies an employee by personnel number and employment number. Each employment gets its own number, so hours can later be traced per employment.
A min-max or on-call contract becomes the minimum as fixed hours and the rest as variable hours, so ONS does not fully schedule a relief worker on hours that are not guaranteed.
The collective agreement goes along per employment, such as nursing care, disability care or mental health care, so someone working in two sectors is scheduled under the right rules per employment.
Only hours the team leader approved in ONS go to payroll. The payroll system gets the number of hours per allowance percentage per employment, so allowance rules live in one place.
Hours go to AFAS and YouForce directly, without a file. YouServe has no entry point for writing hours; there the integration produces the mutation file YouServe imports itself.
Nedap approves every ONS integration before it goes live and limits concurrent requests. The integration therefore fetches a period's hours spread out.

Edge cases we handle

HR2day can temporarily spread an employee's costs over other cost centres. The integration uses the employment's department, so such a recharge does not move the employee to another team.
Creating absence in ONS automatically is still experimental on the ONS side. Whether leave and sickness are included, we discuss per customer.
The mutation file for YouServe only works once Visma has set up the file format in payroll. We put that on the plan at the start.

What KoppelHet does

KoppelHet starts with the smallest working flow and arranges access on both sides: the request to Nedap through the Ons API Dashboard, and the integration user or coordination on the HR side. With HR2day the first integration only sends employees to ONS; worked hours back can follow later as an extension, once HR2day accepts hours through its own entry point. As an indication, allow two to four weeks to go-live.

Frequently asked questions

Can Nedap ONS export hours to our payroll system itself?

ONS has a standard hours export for ADP, AFAS and SDB, but not for YouForce or HR2day. With AFAS someone has to import the file; the integration books the hours directly.

What if a department has no team in ONS yet?

Then the employee is not passed on and an alert appears. Scheduling creates the team or completes the translation table; the next round puts the employee into ONS.

Who arranges access with Nedap and Visma?

Your organisation is the client with both. KoppelHet makes the request to Nedap and coordinates with Visma, together with you.
