How Earnside Is Built
Most processors stop at the rate. Earnside starts there.
We examine your effective rate, processor markup and fee structure line by line, and benchmark it against what fair actually looks like for your volume and card mix.
POS selection, hardware, implementation, integrations, funding and support — the infrastructure that makes payments work at the counter, not just on paper.
An ongoing relationship, not a one-time transaction. Continued optimization, operational recommendations, and a team that looks beyond payments when it matters.
You understand what you're paying, down to the line item.
Your system actually fits how your business operates.
You know exactly who to call when something goes wrong.

“Send me your statement. I'll show you what I see.”
Brad's background spans law and Wall Street before payments — the same financial discipline now applied to reading a merchant statement and knowing exactly where the numbers don't add up. Earnside starts with a conversation, not a product pitch, and stays involved through the switch, installation, training and everything after.
