Three documents from the UAE MoF in one drop is more than we usually get, and the level of detail in the accredited service provider selection criteria is genuinely useful for vendors deciding whether to apply. The 5 corner Peppol model is well established at this point but the UAE specific ASP layer is the new architectural piece, and it has implications for how vendors are differentiating themselves on certification. The mandatory invoice fields document is the one I have spent most time with, there are a couple of fields (the trade licence reference being one) that will require ERP master data work for any business that has not been keeping that field tidy.
