• Login to GoCardless
• More... > Import Payments > Make bulk submission > Generate template .csv file
• Wait for email "Export of your GoCardless customers", export customers.csv to c:\tmp (will probably mean overwriting previous one)
• Go to DWF APMonthlyMaster custom view and in the "GC Batch Submission" area, click Choose File, select the customers.csv and click "GCImportCustomers"
  - You can look for the line something like "Nov 17 2016 10:19:17 2-Imported 67 customers"
• Ensure that "Debug Output" is off
• Go back to the custom view and click "GCCreateBatchFromUpload"
  - That will download a GCBatch file (eg. gcbatch-Nov2016a.csv)

• Save the file into the directory reserved for these things - F:\dmNet16\SwtNetOps16\AutoPay
• Go back to GoCardless web page
• More... > Import Payments > Make bulk submission > STEP THREE > Choose File
• Put in the gcbatch file you just saved and click "Upload"
• Wait a bit for "Ready to Review"
• Check that the count and total are as expected (Compare to the output of GCBatchCheck)
• Submit the batch
