Automatic Payroll Payout - APPK
Automatic payroll payments for Nmbrs
Analyses the payroll administration against more than 50 checkpoints and maps out possible deviations.
- Contract data and working hours
- WAB-related checkpoints
- Wage tax settings and employee insurance
- Deviating percentages, input values and payment components
Why should I purchase this tool?
A small error in the payroll administration can have major consequences. The APPK periodically checks important settings and flags deviations before they turn into problems, so you stay in control of your payroll administration's quality and reduce risk.
Employee Data
Employee data conversion
Transforms employee data in CSV, Excel, or XML files using reusable mappings and validation, then exports the result or sends the supported records to Nmbrs.
- Extensive catalog of employee fields (Nmbrs)
- CSV, Excel, and XML import
- Reusable mappings, transformations, and validation
- Excel export and verified Nmbrs delivery
Why should I purchase this tool?
Stop entering new employees and changes into Nmbrs manually every time. Use one reusable import profile to connect data from your HR system to Nmbrs. This saves you time, prevents retyping errors, and better aligns your HR administration with payroll.
Periodic Mutations
Payroll mutation conversion
Converts payroll data from CSV, Excel, or XML files into validated period mutations for export to Excel or delivery to Nmbrs.
- CSV, Excel, and XML import
- Reusable mapping profiles
- Transformations, filters, and validation
- Excel export and verified Nmbrs delivery
Why should I purchase this tool?
Stop reformatting files or retyping mutations every month. Set up an import profile once, then quickly convert hours, bonus, and other mutation files into period mutations for Nmbrs from now on. This saves you time every month and prevents unnecessary manual work.
How It Works
Three simple steps to eliminate manual data entry from your workflow.
Connect
Securely connect your HR or payroll data via API or SFTP. HRplugin retrieves the required data straight from the source.
Configure
Decide which data you want to check or process. Configure mappings, translations, checks and validation rules where needed. Set up once, then reuse.
Process
HRplugin processes the data automatically. For an APPK you receive the findings and discrepancies immediately, or push validated data through to Nmbrs for import, conversion or migration.

Frequently Asked Questions
Everything you need to know about HRplugin and data integration
What is HRplugin?
HRplugin is a platform of smart tools for HR, payroll and salary processes. With HRplugin you automate manual work, connect systems to Nmbrs and improve the quality of your payroll administration.
HRplugin's tools help with processing Excel and CSV files, connecting HR and scheduling systems to Nmbrs, importing employee data, checking payroll administrations and building reports, among other things.
Who is HRplugin for?
HRplugin is intended for organisations, accountancy firms, payroll providers, payroll administrators and HR teams that work with Nmbrs and want a smarter way to handle data, mutations and checks.
The software is particularly valuable when you have a lot of manual work around payroll, period mutations, employee data, document conversions, reporting or quality checks.
Can HRplugin connect a system to Nmbrs when no standard integration is available?
Yes. HRplugin was built precisely for situations where you want to connect an HR system, scheduling system, time registration system or other application to Nmbrs, but no standard Nmbrs integration exists.
As long as the source system can supply data via Excel, CSV, XML, SFTP or API, HRplugin can process that data and make it suitable for Nmbrs. That way you do not have to wait for a software vendor to build a standard integration.
Can HRplugin convert Excel or CSV files to Nmbrs automatically?
Yes. HRplugin can automatically convert Excel files and CSV files into a format suitable for processing in Nmbrs.
This is ideal for organisations and accountancy firms that receive mutation files every month or every four weeks containing hours, leave, allowances, cost centres or other period mutations. HRplugin reads the file, applies the right mapping and rules, and prepares the data for Nmbrs.
What is HRplugin's period mutations tool?
HRplugin's period mutations tool automates the processing of recurring mutations towards Nmbrs. Think of hours, leave, allowances, deductions, cost centres, wage components and other data supplied per month or per four-weekly period.
The tool saves payroll administrators from retyping or rebuilding mutation sheets by hand. Based on a fixed profile, files are processed the same way every time, which makes processing faster, more consistent and less error-prone.
Can HRplugin import or update employee master data in Nmbrs?
Yes. With HRplugin's employee master data tool, employee details from HR systems or other source systems can be imported into or updated in Nmbrs.
Think of personal details, employment details, contract information, addresses, job data and other master data. HRplugin can convert this data into the right structure for Nmbrs, so new employees and changes can be processed more efficiently.
Which HR systems can be connected to Nmbrs with HRplugin?
HRplugin can be used with a wide range of HR systems, scheduling systems, time registration systems and T&A systems. The approach applies to systems such as Workday, BambooHR, Sage HR, PeopleHR and People Inc, among others.
Other systems can be connected too, as long as the required data is available through a file export, an SFTP location or an API. HRplugin then translates the data into the structure needed for processing in Nmbrs.
Does HRplugin work with the Nmbrs API?
Yes. HRplugin can process data via the Nmbrs REST API. Depending on the process, HRplugin can work with an import file for Nmbrs or with direct API processing.
Which route fits best depends on the source system, the type of data, the desired frequency and how far you want to automate. In both cases the goal is the same: less manual work and a more reliable process towards Nmbrs.
What is the difference between HRplugin and an ordinary file converter?
HRplugin is more than a file converter. The tool can not only convert files, but also map, translate, enrich, combine, split and check the data.
That matters in payroll processes, because data from HR systems, scheduling tools or international systems often does not map one-to-one onto Dutch payroll practice or the way Nmbrs is set up. HRplugin makes sure the data is translated soundly and correctly into the payroll structure you need.
What is HRplugin's APPK?
APPK stands for "algemene periodieke payroll keuring", a general periodic payroll inspection. With APPK you check your payroll administration periodically for deviations, errors and points of attention.
The tool helps flag possible risks in payroll, such as deviating calculation bases, special sickness cases, incorrect or missing data, deviating percentages or other control points. APPK is meant to catch errors earlier and to structurally improve the quality of the payroll administration.
How does HRplugin help with checking the payroll administration?
HRplugin helps with payroll checks by intelligently analysing data from Nmbrs and other sources. With tools such as APPK, deviations become visible sooner, so payroll administrators can check in a targeted way instead of working through everything by hand.
This is especially valuable during year-end work, periodic checks, quality assurance, audits, and in larger administrations with many employees or multiple clients.
Can HRplugin help with document conversion to Nmbrs?
Yes. HRplugin also offers document conversion. Documents from other systems can be prepared for or transferred to Nmbrs, without everything having to be downloaded, renamed or re-linked by hand.
This is particularly useful during migrations to Nmbrs, when cleaning up employee files, or for clients switching over from another HR or payroll system.
Can HRplugin build reports from HR and payroll data?
Yes. HRplugin can be used to develop reports based on HR and payroll data. Think of reports on absence, WAB, departments, contracts, cost price per hour and other management information.
These reports help organisations, accountancy firms and payroll providers gain more insight into their data, without having to create exports and build analyses in Excel by hand every time.
Is HRplugin worthwhile for accountancy firms and payroll providers?
Yes. HRplugin is highly worthwhile for accountancy firms and payroll providers that work with Nmbrs for multiple clients. They often receive Excel or CSV files with mutations, hours, leave or allowances on a recurring basis.
With HRplugin these files can be processed through fixed profiles. That reduces the amount of manual work, lowers the chance of errors, and lets payroll administrators handle more clients without their workload rising in step.
What does HRplugin deliver?
Above all, HRplugin delivers time savings, less manual work and better control. Automating files, integrations, payroll checks and reporting makes processes faster and more consistent.
For Nmbrs users this means data from other systems is easier to process. For payroll administrators it means less retyping, less Excel work and less rework. For organisations it means a firmer grip on HR and payroll processes.
