Hello Shirley bpr, thanks for posting on the Community page, you can only CSV upload suppliers ( cog wheel> import data> download sample file- make sure its the same> browser> open> next map it> then it will import them in for you) or bills into QuickBooks, there is nowhere to enter supplier bank details in Quickbooks, all you can add in is (expense rate, payment- terms/ account no. and opening balance).
You can ONLY enter in YOUR bank details no one else in the custom form styles section in the systems for estimates, invoices, and sales receipts. For the remittance, if you have a look at this link it has all the steps you need to to send a remittance and you can send bulk remittances as well don't have to be just one by one.
