We were looking at Concur before Epicor bought DocStar and went with ECM. We have only been live for a few months, but I am able to make tweaks in the workflows as needed. Our primary AP person has been out for months and we are on our second temp using ECM. Both have been able to process over 100 invoices a day with almost zero Epicor training.
With @MikeGross’s help I have made a few other workflows that have been very useful in attaching documents to Epicor much quicker than without ECM.
