Curious if anyone knows the best way to go about sending bulk payments via wiretransfer or check. Is there any companies out there that can handle this?
How many transactions per day are you referring to? If it is a lot, almost any processor will set up an account for you to accomplish this. Depending on the size etc usually between 1,000 - 5,000 transactions is the minimum. Of course, some gateways will offer bulk upload as well.
Any idea how to automate this? Are there any payment providers or gateways that will handle outgoing payments (i.e. distributions) electronically from a website? I've been searching for days to no avail.
Most processors usually like >5,000 a day but depending on the volume some transaction processors will set up an SSH client for you.
