Questions San Diego Business Owners Ask
Real Answers — No Fluff
Square — Best for Most
Free magstripe reader, $49 for the tap+chip reader. 2.6% + 10¢ per in-person transaction. No monthly fee. Works immediately. Best choice for first-time mobile sellers in San Diego.
Stripe — Best for Tech-Forward Shops
2.7% + 5¢ per in-person swipe. Stripe Terminal hardware is ~$299. Worth it if you need subscriptions, custom invoicing, or integration with your own app or platform.
PayPal Here — Skip It Unless…
2.29% + 9¢ per tap. Fine if your customer base already pays through PayPal. For new setups competing with Square on fees and reliability, PayPal Here loses most comparisons.
SumUp — Best for Low Volume
2.75% flat, no monthly fee, reader is ~$19. Great for occasional sellers — Encinitas farmers markets, Carlsbad pop-ups, one-off service calls. Honest and underrated.
Apple Pay & Google Pay
Square, Stripe Terminal, and SumUp all accept contactless payments including Apple Pay and Google Pay out of the box. No extra setup needed — just tap the reader.
Invoicing on the Go
Square Invoices is free and sends by email or SMS. Stripe Invoicing is more powerful but has a small fee per invoice. For contractors sending jobs-done invoices from a truck, Square wins on simplicity.
