Industry
Payroll is unforgiving: it is right, or it is a very bad Friday.
Reconciliation, multi-jurisdiction rules and integrations with systems that will not change for you. Correctness is the whole product.
Failure patterns
What goes wrong here specifically
Not generic software problems. These are the ones that recur in this sector.
Reconciliation is manual and monthly
Someone compares three systems by hand under time pressure. It works until the month it does not, and that month is expensive and public.
Jurisdiction rules change without notice
Rates, thresholds and filing requirements move. Encoded in application logic, every change is a deployment.
Errors are discovered by employees
Which is the worst possible detection mechanism, and the reason trust is so hard to rebuild afterwards.
What we build
Systems we have shipped in this space
- Reconciliation that runs continuously and flags variance early
- Rules engines where rates and thresholds are data, not deployments
- Integrations with payroll providers and accounting systems
- Employee-facing self-service that reduces the query volume
- Audit trails detailed enough to answer a dispute months later
{{TODO: VERTICALS}} — no published case study in payroll & hr yet — this list describes capability, not evidence, and the page stays unindexed until that changes
Constraints
The rules this sector plays by
Compliance, data handling and integration reality. These are architecture decisions, not a checklist at the end.
Correctness over throughput
A fast payroll system that is occasionally wrong has negative value. Every design tradeoff resolves toward provable correctness.
Personal and financial data
Access control, encryption and retention with real regulatory weight behind them.
Immovable integrations
Payroll providers do not adapt to you. Their API is the constraint and it shapes the build.

Nothing published here yet
An industry page with no evidence is worse than not having the page, so this one does not borrow case studies from another sector to fill the gap. When there is work to show here, it appears in this slot.

FAQ
Questions people actually ask
Can you integrate with our payroll provider?
Depends on the provider, and it is the first thing we check. Some have workable APIs, some have a file drop, and one or two effectively have nothing — which changes what is possible before it changes the price.
How do you test something where errors are this expensive?
Parallel running against real historical periods until outputs match exactly, then continued shadow running after cutover. Nobody switches off the old process on a promise.
What about multi-country payroll?
Each jurisdiction is effectively a separate rule set, and the honest answer is that the second country costs nearly as much as the first. Anyone quoting otherwise has not built it.
Do you have payroll work we can see?
