Algosoft builds Employer of Record platforms that handle the full employment lifecycle — from contract generation and payroll calculation to tax filing, benefits administration, and global mobility workflows.
Building a production-grade Employer of Record platform demands deep expertise in payroll engineering, employment law APIs, and compliance architecture. Our engineering team has delivered 150+ HR technology projects including multi-country payroll engines, employment contract automation platforms, and global benefits administration systems. We understand the difference between building a simple payroll calculator and engineering a compliance-grade EOR system: local tax table management, statutory contribution rules, net pay computation for 30+ jurisdictions, GDPR-compliant data handling across borders, and the document workflow automation that makes digital employment legally binding in each target market.
Our EOR platform builds use a microservices architecture that separates the payroll calculation engine, the compliance and tax layer, the contract lifecycle service, and the HR dashboard into independently deployable components. This approach allows you to expand to new countries by adding a compliance module without touching the core payroll engine — a critical design decision for platforms targeting rapid geographic expansion. We integrate with DocuSign and HelloSign for digital signing, connect to country-specific tax authority APIs for automated filing, and build benefits administration marketplaces with insurance provider APIs. This is part of our broader custom software development practice.

Six reasons global HR technology companies and EOR service providers choose us to build and scale their payroll and employment platforms
We have engineered payroll calculation engines for 30+ countries including complex jurisdictions like Germany, France, Brazil, and India — each with distinct social contribution structures and statutory filing requirements.
We maintain a regulatory change calendar and deliver compliance update sprints as tax laws change — protecting your platform from becoming outdated and exposing your clients to incorrect payroll calculations.
Our contract automation engine generates compliant employment agreements for each target jurisdiction from a configurable clause library — reducing legal review time and enabling same-day contract issuance.
Every EOR platform we build is architected to meet SOC 2 Type II requirements from sprint one — with encryption at rest and in transit, RBAC with MFA, audit logging, and data residency controls.
Our Enterprise tier delivers a fully white-label platform with branded client portals, separate admin environments per client organisation, custom domain deployment, and an API partner ecosystem.
We build open API layers that connect your EOR platform to client HRIS systems (Workday, BambooHR, SAP SuccessFactors), accounting platforms, and banking APIs for automated payroll funding.
