Payroll accounting costs

Many enquiries start with the question, „What does that cost per employee?“. This perspective is too narrow for a credible assessment: two companies with the same number of employees can have very different levels of effort – depending on the remuneration structure, data quality, and number of special cases.

Closely linked duties and concepts: SV reporting procedure, ELStAM, Contribution certificate.

What the costs are made up of

In practice, the costs of payroll accounting can be broken down into four components. For a fair assessment, all components should be considered – not just the processing fee or the software license.

1) Staff costs (internal)

• Processing time for monthly billing and queries
• Cover during leave/sickness, training of replacement
• Further training, specialist updates, internal coordination

2) System and process costs

• Billing software, maintenance, updates
• Interfaces (e.g. Time Management, HR system, Financial accounting)
• Checklist, Approval process, Documentation, Filing

3) External costs (if outsourced)

• Base fee and/or price per employee
• Additional expenses (special invoices, corrections, certificates)
• Effort for handovers, data provision, approvals

4) Risk and failure costs

• Proofreading, revisions, internal clarifications
• Back payments and potential default surcharges for deadline-related matters
• Effort for exams (documents, evidence, queries)

Cost models and typical comparison metrics

In offers and internal calculations, three comparison metrics are typically encountered. Each has its strengths – and each has blind spots.

Price per employee (per month)

The price per employee is easy to understand and straightforward to budget. However, it primarily reflects the billing volume – not necessarily the complexity.

Flat rates per billing run / per service component

Here, calculations are frequently made for process modules, such as for standard billing, corrections, certificates, or special topics. Advantage: Performance and price are more clearly linked.

Internal full costs (hourly rate-based)

For an internal assessment, personnel costs are often allocated to an internal hourly rate. This is helpful if the actual processing time is reliably recorded.

Main cost drivers in practice

Whether payroll accounting is „expensive“ or „efficient“ usually depends on a few key factors. The following drivers are particularly common in practice:

Remuneration structure and types of wages

• Many variable components (allowances, bonuses, one-off payments)
• Regularly changing lesson models and absences
• Benefits in kind and special provisions subject to documentation requirements

Data quality and deadlines

• Late or incomplete reporting of times/absences
• common corrections after the billing run
• unclear responsibilities between HR, management, and accounting

Reporting and documentation requirements

Reports and evidence are not „ancillary“ but a fixed part of the workload. Particularly relevant are SV reporting procedure, the processing of ELStAM-features along with the creation of Contribution records.

Checks and Documentation

Without defined checkpoints, errors often only arise afterwards: returns, follow-up questions, correction cycles. Clean documentation not only reduces the effort of checking, but also internal friction.

Internal vs. External Costs – How to Compare Fairly

A fair comparison starts with a simple rule: it's not „price vs. no price“ that's compared, but Total expenditure vs. Total expenditure. This also includes internal times for data provision, queries, and approvals.

Typical internal efforts that are often missing in comparison

• Collection and review of movement data (times, absences)
• Queries regarding discrepancies, subsequent deliveries
• Release processes (including documentation)
• Forwarding of evaluations to financial accounting / controlling

Typical external additional costs that should be clearly defined

• Corrections after billing run
• Special calculations (entries/exits, one-off payments)
• Certificates and assessments outside the standard
• Support for queries and checks

Typical cost traps

Proofreading as standard practice

If corrections are regularly made after the billing run, costs increase on both sides: additional processing, new evaluations, re-authorisations and, if necessary, adjustments in follow-on processes.

2) Special cases without a standard rule

Every special case is not just a one-off effort, but permanently increases complexity. Clear documentation of standard rules and a decision on which exceptions are truly necessary is advisable.

3) Documentation is built too late

Missing or unclear documentation increases the effort required for queries and checks. Proofs in particular (e.g. Contribution certificatebenefit from standardised procedures and clear filing locations.

FAQ

What factors are particularly driving up costs?

Common drivers include many variable remuneration components, high staff turnover, delayed data delivery, correction runs, and additional duties such as SV reporting procedure, ELStAM and Contribution certificate.

Conclusion

Payroll accounting costs can only be reliably assessed as a complete system: remuneration structure, data quality, control points, and reporting and documentation obligations determine the effort involved. Reducing corrections, clarifying responsibilities, and documenting processes stabilise costs – regardless of whether payroll is processed internally or externally.
