The record

Purpose: RTI Pro collects payroll data from files, processes and validates it, then submits it to HMRC.
Desktop software: RTI Pro is a Windows PC desktop application that submits RTI reports directly from the user’s PC through the Government Gateway.
HMRC recognition: Hartigan says its RTI submission software has HMRC recognition and is used to submit live data to HMRC daily.
Submission types: The product comparison lists EAS, FPS, EPS, EYU, NI number verification requests and Outgoing Data Provisioning Service for RTI Pro.
File imports: RTI Pro can import HMRC RTI standard XML and Microsoft Excel data.
Integration: Hartigan says RTI Pro is designed to interface with existing payroll packages directly or through Excel templates or XML files.
Validation: The software validates data before submission so data issues can be resolved before filing.
Security approach: Hartigan says the software connects directly to the Government Gateway without uploading data to a third-party server.
Optional password controls: The user guide describes optional administrator and submission password prompts in the application’s security settings.
NEST pensions: The RTI Pro user guide includes NEST employer setup, worker enrolment, contribution schedule updates and NEST file submission.
Notable limit: RTI Pro submits previously calculated payroll information; the comparison assigns payroll calculation to RTI Payroll Standard instead.
Support: Hartigan offers standard product support packages or support tailored to a client’s individual requirements.
Company background: Hartigan Software Design Limited says it was formed in 1987 to provide bespoke software solutions and IT support to City financial institutions.
Founded: 1987
Price from: £19.17/mo
