Looking for help with EDI development

I’m currently vetting 3rd party EDI providers.  So I’m interested in your journey.  I don’t know what I don’t know.  We are moving to Acumatica from another ERP system to align with our corporate parent.  We have been using EDI for decades.  Before our company was purchased, we were perpetually under-capitalized, so we developed our own EDI solution for our ERP system.  It was a team effort between customer service, management, and me.  I did the actual development.  The basic concepts are simple:  It's like building with LEGO -- the blue brick goes here and the yellow brick goes there -- data has specific locations.  I don't know enough to know what would be needed to do the same with Acumatica.  Although nobody has said this specifically, there is a question of what would happen if I'm not here -- when/if I'm hired away, fired, retired, or expired.  That's why we're looking at 3rd party EDI partners.  The plan is to move to Acumatica next year, but that was said last year.  I can answer general EDI questions, so contact me -- I just won't have a specific Acumatica answer in the short term.  Also, questions will help me get acclimated to Acumatica and guide our EDI journey.  Thanks, Bruce.

You can use a tool called N8N to create automated EDI workflows. It’s a self-hosted low-code (virtually no-code) tool and it’s easy to configure it and train other users on how to use it.

If you could give some details on what data goes where I would be able to suggest some initial workflows in N8N

ive been using https://alluviaplatform.com/ for EDI. What i really appreciate about them is they tailor the workflow exactly the way i want it, and they are not publishing any bulky customizations like some of the other EDI partners. Any extra fields or workflow customizations i was able to handle.
