About Fortis
Built to control the point at which JSL becomes financial exposure.
Fortis was created by Professional Passport in response to the introduction of joint and several liability across umbrella company labour supply chains. Its purpose is simple: connect accurate payroll calculation with controlled settlement and evidence.
Our mission
Why Fortis exists
To give responsible organisations a practical way to prevent correctly calculated agency-funded PAYE and NIC liabilities from remaining unpaid, while strengthening transparency and compliance across the wider supply chain.
Our principles
What guides the way Fortis is built
Control before assurance
Where an organisation can control a material payment outcome, it should not rely only on retrospective confirmation.
Facts before promises
Evidence should arise from the transaction itself: data, calculation, instruction, payment and reconciliation.
Worker-level transparency
Aggregate totals are not enough. Every material value should connect back to the worker and assignment that created it.
Independent scrutiny
The organisation behind the payroll matters. Ownership, contracts and operations should be reviewed alongside calculations.
Precise claims
Fortis should be clear about what it controls, what users must do and where limitations remain.
Heritage
Part of Professional Passport
Professional Passport was established to provide independent assessment and compliance standards for providers operating in the flexible labour market. Fortis builds on that experience with a purpose-built technology and control process for JSL-era payroll funding.
How the independent review worksFortis provides payroll-calculation, payment-instruction, reconciliation and compliance-support services. It does not provide legal or tax advice and does not receive or hold client money. The effectiveness of the process depends on complete and accurate data, correct operation of the agreed workflow, successful payment and allocation, and the proper handling of corrections and later liabilities. Organisations should obtain advice on their own legal and tax position.
