Each row represents a contract. Contracts typically have up to 4 deliveries. In the text of each contract it will specify the maximum box size for that contract. Take that number and enter it into the "Max Box Size" field.
If a contract has more than 4 deliveries, just add a new row and fill it out to make up the additional deliveries. If you have more than a single contract you can add additional lines to cover those.
In each delivery box, enter the SCU found in the contract. See the example image to the right. **NOTE** This only calculates on-grid configurations. Off-grid is up to the user to attempt.
