Microsoft normally expect you to have one "Partner of Record" associated with your Dynamics 365 Finance installation. That's probably best practice to ensure consistency across a company - and only one "throat to choke" if there is any issue needing to get sorted.The partner who helped us run up our installation tends to specialise in large multinational food and process manufacturing customers (where we are in Education - about as far from!). They historically have a lot of on-premise AX clients, where we are 100% cloud based. The implementation was really a rushed minimal viable deployment (in four months), with us using ledgers, journals and banking; we are subsequently enabling sales functionality and purchase functionality. Our gotcha is that we had to go to tender the quote to cash piece, which a different vendor won - so we're only the early stages of having a mix of two partners active on the same installation. The new partner is also much more closely aligned to the public sector markets we sell into.The advice we got from one of the initial reference sites we engaged with was that the critical asset for success was the quality of the functional consultants we managed to get assigned on our project (quality within any partner company can be variable). 2.5 years later, we can see that was great advice - and have sufficient experience to know some of the nuances in the partners we deal with.
Good luck on your journey :-)
