How does the volume part of your package pricing work?

Volume is based on the green coffee you roast each calendar month and is separate from your package price. For this reason it also appears as a separate line item on your invoice.
The first 250 kg/500 lbs of green coffee roasting each month is included in the package price (Foundation & Professional).  Volume pricing is degressive, meaning, the price per kilo/pound of green coffee consumed decreases as your volumes increase.null

For example:
If you roast 500 kg of green coffee per month and you are on the Foundation package the volume charge will be 3.4 cents per kg or 17.00 per month in addition to the monthly package. 

If you roast 5,000 kg of green coffee per month and you are on the Foundation package the volume charge will be 2.8 cents per kg or 139.00 per month in addition to the monthly package

When will I receive my first bill?

Your first bill will be calculated at the beginning of the month following the end of your 14-day free trial. You will then receive your bill monthly at the beginning of each month and it will be updated based on the previous month’s volume. Please note: your initial bill may take longer based on the start date of your trial (your first roast) and other factors.
