Payroll runs validated before submission, worldwide: 99.4% first-time pass rate across 40+ countries

Payroll infrastructure that explains itself — in every country you operate.

Claripay validates draft payroll data against each jurisdiction's tax and statutory rules, explains every failure in the recipient's own language and produces a complete audit trail. Add premium modules and it also calculates tax and net pay, and generates and sends payslips — from the same platform.

One validation engine. Every jurisdiction's rules.

Each country runs its own statutory rule pack — tax, social security and reporting logic — behind the same ingest, validate, explain, resolve and assure pipeline.

Product proposition

Every payroll checked, calculated, explained, assured — and paid.

One continuous pipeline turns raw payroll data into a submission-ready, auditable outcome, and — with premium modules switched on — carries it all the way through to employee payslips, in every country you run payroll.

1

Ingest

API, secure file upload, or native Claripay payroll feed — any country, any format.

2

Calculate Premium

Gross-to-net tax and statutory calculation, per jurisdiction.

3

Validate

Technical, statutory, payroll, historical and fraud checks — tuned to each jurisdiction's rules.

4

Explain

Plain-language failures with cause, impact and recommended action — in the recipient's local language.

5

Resolve

Fix, accept with reason, exclude, or escalate for review.

6

Assure

Score, evidence, report and submission readiness for every authority.

7

Pay Premium

Generate branded payslips and deliver them straight to employees.

Premium modules

Validation is the foundation. Calculation and payslips are the upgrade.

Turn on either module independently, or run both together so one platform takes payroll from raw data all the way to a paid, payslipped employee.

Premium Tax calculation engine

Stop checking figures someone else calculated. Calculate them correctly the first time.

A jurisdiction-aware gross-to-net engine sits alongside the validation layer — so Claripay can calculate statutory tax, social security and net pay directly, not just check it after the fact.

  • Gross-to-net calculation per jurisdiction, kept current with local rate and threshold changes
  • Income tax, social security, pensions and statutory payments in one pass
  • Multi-currency and multi-frequency (weekly, monthly, supplementary) support
  • Calculated figures flow straight into the validation and assurance layers

Premium Payslip delivery

The pipeline doesn't stop at "ready to submit." It ends with employees getting paid, and told why.

Once a run is calculated and assured, Claripay generates a branded, localised payslip for every employee and delivers it automatically — no separate payslip tool to reconcile against.

  • Auto-generated payslips from the same calculated, validated figures
  • Localised templates — language, currency and statutory line items per country
  • Delivered by email or secure employee self-serve portal
  • Full delivery and read-receipt audit trail, alongside the assurance report

Recommended architecture

Start modular. Extract services only when scale requires it.

A single, well-structured application sits between every payroll source and every tax or social security authority you submit to — deterministic where it counts, intelligent where it helps.

  • Ingestion layer — REST API, secure upload, SFTP/HTTPS and direct integration adapters.
  • Calculation engine Premium — gross-to-net tax and statutory calculation, per jurisdiction.
  • Validation engine — technical, local statutory, payroll, historical and fraud rules, per jurisdiction.
  • Failure intelligence — rule library, explanation engine, recommendations, severity scoring and localisation.
  • Core services — workflow, audit, reporting, notifications, users and roles.

Governed AI layer

AI explains and prioritises. It never decides a tax outcome.

Specialist agents with limited tools sit around the deterministic rules engine — not inside it. Every explanation is source-linked and auditable.

💬

Explanation Agent

Plain-language cause, impact and next step — in the recipient's own language.

🛠️

Resolution Agent

Suggests safe fixes using prior cases and country-specific context.

📊

Risk & Anomaly Agent

Summarises unusual patterns and prioritises review, across regions.

📄

Reporting Agent

Generates assurance narratives for managers and audits, per country or globally.

🎧

Support Agent

Answers user questions from product & local payroll knowledge bases, in the user's own language.

Every finding, reported and communicated in the local language.

A payroll admin in Dublin, an employer in Berlin and a bureau in Paris shouldn't all get the same English error message. Findings, recommended actions and portal notifications are generated directly in the recipient's own language — not bolted on with a translation layer afterwards.

  • Explanation and Support agents respond natively in the local language
  • Payroll and tax terminology reviewed per jurisdiction, not machine-translated blind
  • Language follows the recipient — payroll admin, employer or employee — not just the country
  • Portal, email and payslip communications all use the same localisation layer

Payment after leaving treatment missing
Why it matters
Wrong tax treatment may be applied.
Recommended action
Confirm the payment date and apply the correct treatment.
Illustrative machine translation — production wording needs native tax/legal review per language.

One API. Every jurisdiction. Every language. The same explain and resolve endpoints work whether the finding is against HMRC, the IRS, the ATO or any other tax or social security authority — and return in the language the caller requests.

Five validation layers, per jurisdiction

Deterministic checks build the assurance score.

Tax and compliance outcomes stay deterministic in every country. AI assists with explanations, prioritisation and resolution wording — never the decision itself.

01

Technical

Schema, mandatory fields, data types, dates, duplicates, tax year.

02

Statutory & tax rules

Local tax authority rules — PAYE/NIC (UK), FICA/941 (US), STP (AU), source deductions (CA) and more.

03

Reasonableness

Unusual net pay, negative pay, pay after leaving, pension reconciliation.

04

Historical

Prior runs, employee norms, seasonal patterns, rejection history.

05

Fraud / misuse

Same bank account, late bank change, duplicate ID numbers, overrides.

Security, audit & operational controls

The multi-jurisdiction gateway model demands stronger controls than a standard payroll feature.

🔒 Tenant & region isolation

  • Tenant and jurisdiction enforced in middleware and model scopes
  • Role-based access and API scopes
  • Partner-specific credentials, region by region

🛡️ Data protection

  • Signed URLs with strict expiry
  • TLS everywhere, encryption at rest
  • PII masking in logs, no raw payloads in error tools

📋 Audit & resilience

  • Immutable audit events, per-jurisdiction rule version history
  • Queue retries and dead letters
  • Four-eyes approval and incident playbooks
Implementation roadmap

Build the lowest-regulatory-complexity route first, then expand country by country.

Recommended pilot path: your home market → one additional country → a regional cluster → full global rollout.

Phase 1

Core engine

API, rules, explanations, audit trail, report and sandbox — for your first country.

Phase 2

Intelligence

Historical comparison, anomaly detection, assisted fixes, dashboards.

Phase 3

Gateway

Authorisation, submission, responses, retries, status centre — per tax authority.

Phase 4

Network

White-label portal, partner billing, bureau tooling, powered-by, across regions.

Plans

Start with assurance. Add calculation and payslips when you're ready.

Both plans run on the same ingest, explain, resolve and audit-trail foundation — Premium just carries the run further.

Standard

Validate and assure payroll before it's submitted.
  • Ingest from API, file upload or native feed
  • Five-layer validation, per jurisdiction
  • Plain-language explanations and resolution workflow, in the local language
  • Assurance score, evidence and audit trail
  • Tax & net pay calculation
  • Payslip generation & delivery
