Frequently asked

Can I use Stripe for in-person payments?

Yes, via Stripe Terminal. But you'll need to order hardware and do developer setup. Square's reader works in 10 minutes — Stripe Terminal takes a day or more to configure properly.

Is Square free?

The base plan has no monthly fee — you pay 2.6% + 10¢ per in-person swipe. Square for Restaurants, Retail, and Appointments have paid tiers with more features.

Which is better for San Diego small businesses?

Most SD service businesses (contractors, salons, food) should start with Square. Tech companies, SaaS founders, and e-commerce builders should use Stripe. When in doubt, text PJ and describe the situation.

Can I switch later?

Yes, but it's painful — especially subscriptions on Stripe (migrating recurring customers requires careful token transfer). Choose correctly upfront. One conversation with PJ can save weeks of migration work.

What about PayPal?

PayPal is fine for occasional one-off payments but fees stack up fast. For anything volume-based or customer-facing, Stripe or Square will save you money and give better UX.

Still not sure which fits your business?

Text PJ the situation — what you sell, how customers pay, and what's broken with your current setup. Get a clear answer fast.
