When are you typically billing a maintenance contract?
- All upfront
- At the beginning of each period (month, quarter, etc...)
- At the end of the period
- Other?
If billing at the beginning of the period, how do you manage billing of additional items/services there were not part of the original contract?
- Send a separate invoice for the additional items/services immediately
- Bill the additional items/services on the next period billing
- Other?
