Editorial guidance for this audience
What to evaluate when you collect card payments as small business.
Start with the dominant channel
If 80% of dollars swipe in person, optimize readers and receipts first. If 80% pay online, prioritize checkout and payment links.
Read statements monthly
Effective rate beats marketing percentages—track refunds, AMEX share, and chargebacks.
Pair with invoicing deliberately
Send invoices and accept payments through workflows your office will repeat daily—see our invoicing hub when documents drive collections.
Plan for growth
If memberships or ecommerce appear on the horizon, pick a processor that supports recurring billing without a painful replatform.
Why these picks work for this use case

Square
