"Implementing 123 works has already made a significant impact on how we operate, with the new sub contractor module delivering clear value and strengthening the efficiency of our financial and operational processes. Our teams have quickly embraced the self service tools for timesheets, expenses, and holiday bookings, which are now some of the most widely used and appreciated features across the business."

★★★★★

"Switching to 123 Works has completely changed how our commercial teams handle invoices. We used to spend hours every week keying in invoices manually - slow, error prone, and a constant drain on the team. Now invoices arrive digitally straight into our ERP clean, structured, and ready to process. The accuracy is night and day, and the time savings are enormous. Our QSs and accounts staff have gone from data entry to actually managing the numbers. It’s one of those rare changes where everyone immediately felt the impact. Faster processing, fewer mistakes, and a smoother month end. For a business of our scale, the efficiency gain is huge - 123 Works has taken a painful process and made it effortless."

Finance Department Manager, Higgins Group

★★★★★

"123-Works seamlessly interfaces with our ERP in both directions, so that nothing is rekeyed. Our workforce are using both the APP and web, which has eliminated Paper, while maintaining a full audit trail of the transactions and Approvals. Transactions now post straight into the Project Costing and Payroll. Also we are rolling out the 123-Works Subcontractor Module across the business, which fully manages the Sub-SC financial transactions to give us full control of Sub-SC Applications, Notices and Forecasting."
