Salary benchmarks
Our take
Xelix helps enterprise finance teams detect high-risk transactions and prevent financial losses driven by error or fraud. The solution also provides a deep analytics capability in the areas of cash management & supply chain performance.
Currently, up to 1% of company spend is lost due to Accounts Payable errors. This can be caused by simple manual errors (e.g. keying mistakes), technology mishaps (e.g. OCR failures) or intentional fraud from inside or outside the company. When trying to maximize the profitability of a company a 1% difference in net spending can make an immense difference, therefore the software that Xelix is developing has huge potential.
As evidence of its power, Xelix claims that it typically saves companies 6-figures within the first 3 months of going live and drives a positive ROI within one month. Additionally, its analytics capability provides in-depth analysis & insights on supply chain activity - including payment performance, procurement trends & working capital management. Ultimately, Xelix has the first-mover advantage in its market and if keeps progressing at its current pace it could easily grow rapidly.
