Keep the payroll engine you've trained your team on. project b. adds an intelligent intake layer on top — nothing underneath has to change.

Where project b. fits in your stack

A thin layer between messy data intake and your existing payroll engine.

1

Data arrives

Clients, HR, and employees send changes in any format. Email, PDF, scans, portal entries — all flow into project b.

2

project b. preps & validates

RITA extracts, structures, and checks the data. You approve. A clean, audit-ready record is built.

Your system processes

  • Your contracts and existing system relationships

  • Audit-ready trail for every approval and export

How the handoff actually works

Native export formats

ASCII, LUG, CSV — each system gets the format it expects. No conversion scripts, no glue code.

Field-level mapping

Master data and change records map directly into your system's schema. Configure once at setup, then forget.

Document round-trip

Generated payslips and reports flow back into your DMS automatically. Filing stays organized.

Pre-export validation

Every record is plausibility-checked before it leaves project b. Errors get caught here, not at month-end.

Reversible by design

No data leaves your system. Your processing engine remains the system of record — you can roll off anytime.

Quick onboarding

Live in under 5 days. Existing master data import, mapping setup, and first parallel run — all guided.

Frequently asked questions

Do I have to migrate my data?

No. project b. works with your existing payroll system. Master data syncs in either direction at setup, but your historical records stay exactly where they are. Your payroll engine remains the system of record.

Can I roll off project b. later?

Yes. Because we sit on top of your existing system, removing project b. just means going back to direct intake. Your data, history, and processing engine are unaffected.

What if my system isn't listed?

DATEV, Agenda, and SBS cover the majority of the German market. If you use a different system, talk to us — generic CSV/ASCII export covers many additional cases, and we evaluate native support based on demand.

How long does setup take?

Most teams run their first parallel payroll within 5 days. Master data import, field mapping, and user setup are guided by our onboarding team. No IT project required.

Will my team have to learn two tools?

Your payroll specialists work primarily in project b.'s intake and review surface, then export to your existing system as they do today. Your processing UI doesn't change.

Keep your system. Gain a smarter front end.
