  • Reduce supplier disputes by eliminating typos and other keying errors

We’ve seen a significant improvement in the amount of time it takes the CSD team to upload invoices which has been of great help in an environment where we are asked to do more with limited resources. What used to take up to 2-3 minutes per line to upload now takes 2-3 seconds per invoice regardless of the number of lines since i2x populates all the line item details.
