Payment Processing: Batch vs. Real Time

For example, some catalogers opt to use real time for first contact with new customers. But once a customer is established, the need and expense spent on real-time authorization diminishes.

* Will your volume of transactions create economies of scale? Some merchants produce enough transaction volume to justify conducting all of their business in real time. The more transactions processed, the more their costs decrease. For these large-sized companies, mega volume translates into lower per-transaction costs without the cost in upkeep or administration of two authorization systems.
