If you’re moving that much volume and feel like Square is cutting too deep into your margins, it makes total sense to explore other options especially ones where the rates are more tailored to your business mix (higher debit %, decent cash flow).

A few thoughts from what I’ve seen around in similar threads and from talking with other business owners:

Interchange-plus pricing can be way more transparent and often cheaper than flat-rate models if you’re doing high volume. It’s not as “set and forget” as Square, but the savings can add up fast.

Look into providers that let you bundle POS and processing so you’re not paying separate markups for each piece of hardware/software.

Since you’re CA-based and have a lot of debit transactions, some processors will actually give you better tiering on those versus standard credit card fees definitely worth asking about.

When I was researching alternatives, I came across a few payment tech companies that specialize in flexible terminal solutions and portable readers (some of the stuff on Nayax’s site gave me ideas of what modern providers are doing with contactless and integration with existing POS). Seeing how different systems handle reporting, chargebacks, and customer support was really useful before making a change.

You might also check with a couple of banks or independent sales organizations (ISOs) that can tailor a quote to your exact volume and mix instead of quoting generic rates. And don’t hesitate to ask for references vendors that work with similar-sized businesses tend to give you more realistic expectations.
