Updating Vendor Payment Methods Via CSV (Business Central)
The plugin allows users to update their vendor payment information in bulk using a Comma-Separated Values (CSV) file, eliminating the need to manually change each vendor record.
Keep in mind that information stored within native Business Central fields (outside of the plugin) cannot be updated using this plugin functionality.
Export and Import Functionality
This functionality allows you to manage your vendor records through a two-part process: Export and Import.
- Export creates a file containing all your current vendor records.
- Import allows you to update existing records by applying changes to your vendor data.
Always export first before you begin an import. This is the best way to ensure the CSV file is structured correctly, as the row format changes depending on the type of data you are working with.
You can re-import the same data multiple times to update existing rows, provided the ID fields in the file have not been modified or changed.
Export
Follow these steps to complete the first part of the process, exporting the CSV file.
Navigate to Payment Methods
From anywhere in Business Central, you can navigate to the Payment Methods page.

Click on MUFG Connect and then Payment Methods to begin the export and import process.
Export CSV
Click Import/Export and select Export CSV File to create a CSV export file for all vendor records.

IMPORTANT: The CSV is pre-structured for import functionality; do not modify the column structures.
The import from Business Central triggers a minimum of one row of data. There are three different data types:
- BANK ACCOUNT: Each vendor with a bank account creates a row with a data_type of BANK ACCOUNT, allowing you to modify the vendor’s bank account.
- ADDRESS: Each vendor with an address record creates a row with a data_type of ADDRESS, allowing you to modify the vendor’s address.
- EMAIL: Each vendor with an address record creates a row with a data_type of EMAIL, allowing you to modify the vendor’s email.
NOTE: Save a copy of this file for your records so you can easily re-import the original if necessary.
Import
Once you have exported the existing vendor bank information, create the import file containing your revised vendor bank information by editing the data and adding new rows if you are incorporating new vendors.
Do not remove any of the column headers or add additional columns; otherwise, the import will fail.
Prepare the File for Import
Each of the three data types requires specific data fields. Use the existing records as a guide to which columns require data, and be sure to follow the general rules to avoid errors that prevent a successful import.
- BANK ACCOUNT: To add a new bank account, add a row and enter BANK ACCOUNT in the data_type column.
- ADDRESS: To add a new address, add a row and enter ADDRESS in the data_type column.
- EMAIL: To add a new email, add a row and enter EMAIL in the data_type column.
Please do not fill in the email or address fields for these columns, and ensure that the other columns are completed according to the guidance provided in the table below.
NOTE: Only one line entry per vendor can have the is_default_account set to Y. Enter the default_payment_method for the default account address record.

Fill the CSV Table
You need to use specific default_payment_method code values that correspond to your payment rail types.
Since a vendor can only have one default account with a default_payment_method, you must ensure the payment method you choose is compatible with the corresponding data type.
Navigate to Plugin → Payment Methods and check in the table which payment methods are listed for a vendor.
Here is a complete list showing which payment rail types are supported by each data type. Use only the payment rails supported by your plugin for this specific vendor.
CSV file - table rows
data_type | Compatible default payment_method(s) for this data type | Other rules |

Importing CSV
Once the file is ready, click Import/Export and select Import CSV File.

Attach the file that is ready to import and enter one valid email address to receive a status update.
NOTE: You are not able to modify this email address after clicking Import. If the email is incorrect, you will not get the status email, but the import will complete.

Once the file has been uploaded, a checkmark confirmation message will appear.

Wait a few minutes to get a status update via email.
Import Confirmation Email
Once the import status changes, you will receive an email notification.
This email notification will let you know if the import has been successful. There are 3 options:
File Successfully Imported

Import is successful, but there are line errors.
- In that case, please download the CSV attached to the email that lists those errors and submit the file again. You may leave the error column in the newly uploaded CSV. Please note that if an error is found in one of the rows, none of the information present in that row will be updated.

Import was not successful.
- This issue may be caused by internet connectivity problems or unsupported file formats. Please verify your internet connection, refresh the page to attempt again, or contact support if the problem persists.
Import CSV Example
This file shows an example of what the import file can look like for one hypothetical vendor.

In BC365, when you select the vendor, it shows that the new bank account has been added.

When you open up the bank account, you can see the values match the import.
