Problem
Companies expanding internationally often rely on spreadsheets, external consultants, and manual processes to calculate gross‑to‑net payroll and file taxes. This approach is error‑prone, time‑consuming, and risks non‑compliance with rapidly changing local regulations. The lack of standardized, programmable payroll infrastructure makes it difficult to launch payroll services in new markets quickly.
Solution
Flux delivers a cloud‑native payroll infrastructure accessed via RESTful APIs that automate gross‑to‑net calculations, tax withholdings, and statutory filings for each supported country. The platform continuously updates its compliance engine with local law changes, ensuring that every payroll run meets regulatory requirements without manual intervention. Integrated tax payment routing submits payments to authorities on schedule, while a 100 % accuracy guarantee backs the service and covers any penalty costs. Developers can embed the APIs directly into payroll, HR, or fintech applications, reducing time‑to‑market from months to weeks. The service scales on a multi‑tenant architecture, providing high availability and audit‑ready logs for enterprise governance. Initial coverage includes major European and Latin American jurisdictions, with a roadmap to add additional markets globally.
Target Audience
Primary customers are payroll SaaS providers, HR technology platforms, fintech companies, banks, and accounting firms that need to launch or extend payroll capabilities across multiple countries without building country‑specific infrastructure.
