That's a great question. Here are some things to consider:
Research the integration methods of the software. They don't all work the same.
2. Processing Fees
This is a very unregulated market. The fees fluctuate greatly. Know the differences between the major card processors.
How much money do you have to send on this? There are free versions that take money on the back end (usually higher) and paid versions that take less on the back end).
Does that help answer your question?
