Our business is audio conferencing. We need to import minutes as line items for customer usage after each month and charge these as Metered Component in Chargify.
Import and calculate the usage in Excel, and would like to upload a billing file that imports this via the API to Chargify on the customers.
Typically there is a minute charge for the use (eg. 200 minutes) and a surcharge for some contries on top, eg. €0.07 ekstra for dial-in to India.
