Allow agents to buy now, schedule later - count "account credits" per SKU

I would love if there was a way to sell credits to agents so that they can purchase even if they are not ready to book a time slot. This is especially valuable for time-based offers. For example “buy one get one free special through the end of the month.” An agent might not have a listing before the end of the month, but they may be interested in purchasing with the ability to book that shoot later.

Or another example, if you announce an upcoming price increase at the beginning of the year, you could offer agents to purchase shoots at today's price and be able to book them next year after the price increase. This would have to be done with “credits” per SKU/item, rather than a cash account balance for each agent.

Synergy with another feature request here, titled “Enable Credit-Based Pricing and Redemption for Real Estate Media Services”. Both of these together would be amazing. This way if an agent has a “Credit” for a drone add-on, they can only use it for drone, not a discount on photos. Or if add a virtual twilight image to their account and your pricing goes up, the agent can still claim their “virtual twilight credit” without having to pay the difference due to the price increase.
