I have a requirement to post/push the Supplier Invoice information into the Finance Platform for Supplier Invoice reconciliation. I have explored the list of Open APIs and found that the closest one for my requirement is TMF666, not sure though. Is my understanding correct or is there a different API which I need to use?
Please clarify, are you referring to information about how to generate ongoing invoices, or rather to a specific invoice.
TMF666 Account Management includes entities such as SettlementAccount and BillingAccount, that can be used to manage the financial relationship between service provider and its providers/partners or customers.
TMF678 Customer Bill Management relates to a specific bill on the customer side. Some work was done recently on partner settlements in the ZTP project, I'm not so familiar with the changes in that area, and it looks like they are not published yet.
