If you are a flooring manufacturer/distributer, do not use TrueCommerce
I'm not going to say who I am or who I work for, but it probably wouldn't be hard for TrueCommerce to find out. Flooring EDI is a different animal than other industries.
We've worked with SPS Commerce and OpenText, we agree SPS isn't easy to work with but they at least make it work. We also can attest OpenText will at least make it work (albeit under pressure from the manufacturer).
The issue with TrueCommerce is we've had several issues across several vendors. The first client of theirs under b2bgateway, it was like getting an act of Congress to get them to do anything, but at least they eventually helped the customer after a month.
However, more recent clients under the main name have been horrific. We've had truecommerce expect two different distributers share an edi relationship with their retailers (which violates anti trust laws). One of those distributers dropped truecommerce due to how bad they were to work with. The other one seems like they're stuck in a contract, and they refuse to budge on what the flooring industry expects, nor will they escalate our issues to management.
I get it, in other industries truecommerce isn't that bad, but in the flooring industry they are terrible.
