I think if you choose SPS Commerce willingly, you hate money and like buying contractual failure.

SPS Commerce is forced onto our organization. I think it's their business model. They purchased our dedicated in-house translator with the acquisition of Data Masons. I'm here to lower their score and tell the truth about SPS Commerce. First, in my 20 years of experience with EDI I think they are hands down the worst performing, least experienced developers in EDI. We have evidence of their numerous failures. In my opinion, their business model is to approach retailers and hijack their vendor base, creating programs and forcing compliance with retail executives who are eager to please SPS Commerce as it lowers their cost of EDI. I believe if consumers learned how much SPS Commerce is costing them as a middle man in the retail supply chain there would be a revolt. But no, instead, in my experience, SPS Commerce crams Google search results with their marketing and, in my opinion, they pay reviewers to come to sites like this and write their obviously scripted praises, damage control, instead of letting the truth come out. I've been approached by former SPS Commerce employees critical of them who've let me know the company was coming at them legally in their new jobs for derogatory comments towards SPS Commerce. In my opinion, they are truly a bad company, filtering their lies and using contract law as revenue while failing to deliver on a near constant basis, meanwhile proclaiming themselves leaders in EDI. I think [...] and crew bought their way to the top, it was never about performance. In my opinion, avoid the scam, pick any other EDI solution or provider and vendors should NOT agree blindly to initiatives presented by SPS Commerce as "mandatory". You probably don't have to participate in what they're calling mandatory if you're a valued supplier.
