Customer Accolade

 "We were pressed for time and our manual process made it difficult to complete the RFP on time. We decided to use eSource by triSaaS and were delighted (and surprised) at how quick it was to analyse the suppliers' bids. After using the software for the first time, we'll never go back to the old way of tendering.”
