RE: request for explanation of E-Commerce third party and transaction - Dynamics 365 commerce
Hello,
Yes it's a fixed price, Band / TIER of e-Commerce is per amount transactions done in average and total of transactions, that's it. You have to calculate your AOV estimated for that.
The e-Commerce will give also a Commerce Scale unit for that. (mandatory)
And D365 Commerce is needed too for the backoffice / D365 HQ : for your key user that do setup / config / do retail stuff on F&O side.
(Could be attach ones or FULL)
