We are using the Electronic Bank Payments module of NetSuite. Our bank supports the standard payment file template for ACH payments. But for domestic and international wire transfers, they require a different payment file templare with XML file extension. How does this work? Do we then have 3 payment file templates for the same bank GL account which means 3 different Company Bank Detail records but linked to the same bank GL account? The user then has to process the 3 different payment methods (ACH, domestic wire and international wire) separately?

Yes you need to have 3 file format for 3 same company bank details or else it should create a custom format which is capable of being dynamic based on criteria

Thank you!
