Affiliate Disclosure
Editorial TransparencyWe earn commission on processor sign-ups through our links. This doesn't affect our ratings or editorial independence.
How we're paid
When you click through to a processor's site from our comparison tables and open an account, we may receive a one-time referral fee or a share of merchant fees.
How we rate
Ratings come from our editorial team using a fixed scoring rubric — pricing transparency, contract terms, support quality, and integration depth. Compensation is never an input.
GoFlowPay maintains affiliate partnerships with a subset of the payment processors we review. When a reader signs up with one of these processors through a link on our site, we may receive a referral commission at no additional cost to the merchant.
Our review and ratings team operates independently of our partnerships team. Editors do not see commission rates, and partnership status has no bearing on a processor's rank, score, or featured placement. Processors we have no affiliate relationship with appear alongside — and often above — those we do.
We disclose every commercial relationship on individual review pages and update our disclosures quarterly. For the full breakdown of our scoring rubric and editorial policies, see our review methodology and editorial standards.

How to Start Accepting Card Payments: Complete Small Business Guide
If you are still cash-only, every card-preferring customer who walks out is lost revenue. Setting up card acceptance is faster and cheaper than most owners think. This guide walks you from zero to taking your first card payment.
Step 1: Choose a Processor
Decide between flat-rate (Square, Stripe — simple, predictable, best under ~$10k/month) and interchange-plus (Helcim, Stax — cheaper at higher volume). For a brand-new business, start flat-rate; revisit when volume grows.
Step 2: Decide In-Person, Online, or Both
In-person needs a reader or register. Online needs a payment gateway and a checkout page. Many processors do both from one account, which simplifies reconciliation.
Step 3: Get Your Hardware
For a counter, an all-in-one register is the least-hassle path. For a service business on the move, a mobile reader paired to a phone is enough to start.
Step 4: Set Up a Receipt Printer and Drawer
Even card-first businesses need a receipt printer and a cash drawer for change, tips, and the occasional cash sale.
Step 5: Understand the Fees
Expect roughly 2.6%–2.9% plus a fixed per-transaction fee on flat-rate plans. Watch for monthly minimums, PCI fees, and statement fees — read the fee schedule before signing.
Step 6: Stay PCI Compliant
Use your processor's compliant hardware and never store full card numbers yourself. Most modern readers handle compliance for you.
FAQ
How fast can I start? With a flat-rate processor and a reader, often the same day.
What is the cheapest way to start? A mobile reader plus your phone, then upgrade to a register as volume grows.
Are there contracts? Flat-rate processors are usually month-to-month; interchange-plus may have terms — check first.
Bottom Line
Pick a flat-rate processor, get a register or mobile reader, add a printer and drawer, and you can take your first card payment within a day — for a few hundred dollars in hardware.
