SMS System is a UK sponsor licence compliance software designed to help organisations manage their duties as licensed sponsors under the Skilled Worker visa route. The platform provides tools for tracking UK Visas and Immigration (UKVI) deadlines, extracting data from Certificates of Sponsorship (CoS), and generating audit ready evidence packs. Its primary function is to reduce the risk of sponsor licence revocation by automating compliance monitoring and reporting. The software includes several key features. A sponsor register lookup allows users to check a company’s official sponsor status and rating against the cached Home Office register of licensed sponsors. An eligibility checker evaluates whether a job title and salary meet the required SOC code and salary thresholds. The system uses AI to automatically extract fields from uploaded CoS documents, building a compliance record for each sponsored worker. It tracks expiries for visas, CoS, BRPs, and passports, with escalating alerts as deadlines approach. Users can log changes to salary, role, or location, and the system calculates the exact UKVI reporting deadline. The dashboard surfaces workforce statistics, open actions, and upcoming UKVI deadlines in priority order. Typical use cases begin with a free check or lookup that requires no signup. Users can confirm a role’s eligibility or check their company’s register status. When they create an account, the results from the free check are carried over automatically. Users then upload their team’s CoS documents, and the AI extracts all relevant fields. The system subsequently provides expiry alerts, tracks reportable changes, monitors payroll drift, and maintains audit ready evidence. The workflow is designed to guide a compliance lead from an initial dashboard overview through to producing an audit pack for a visiting UKVI officer. The platform is web based and requires no local installation. It is intended for UK employers holding or applying for a sponsor licence, particularly those sponsoring workers under the Skilled Worker route. The free tools are accessible without an account, while the full compliance system requires registration. The software is hosted at smssystem.co.uk.
