Common questions about merchant accounts, payment processing, Authorize.Net, pricing, and getting approved. Can't find what you need? Contact our team.
A payment gateway (like Authorize.Net) is the technology that securely transmits card data from your website to the payment networks. A merchant account is the bank account that receives and holds the settled funds from those transactions.
You need both. START Merchant Services provides a bundled solution — merchant account + Authorize.Net gateway — so you don't have to coordinate two separate vendors.
Most merchants are approved within 1 to 5 business days, and some can start accepting payments in as little as 1 day. Once your merchant account is approved, we set up your Authorize.Net gateway within 24 business hours for most clients.
High-risk businesses, such as CBD or firearms sellers, can take longer because the bank asks for more documents. A complete application is the fastest one: missing documents and a website without a refund policy are two of the most common reasons an application stalls. See fast merchant account approval or how long merchant account setup takes, step by step.
Each step in detail: how to open a merchant account, and setting up the Authorize.Net gateway.
Interchange plus (also called cost-plus pricing) means you pay the card networks' actual cost for each sale, called interchange, plus a fixed markup from your processor. The two parts are listed separately on your statement, so you can see what the networks charge and what your provider charges.
Example: 1.80% interchange + a 0.20% markup + 10¢ = 2.00% + 10¢ on that sale. START prices merchant accounts with interchange plus. Learn more in our interchange plus pricing guide.
Tiered pricing sorts your sales into a few buckets, usually "qualified," "mid-qualified" and "non-qualified," each with its own rate. The processor decides which sale lands in which bucket, and you can't see what each card actually cost.
Interchange plus passes through each card's actual interchange cost and adds a fixed markup. When a customer pays with a lower-cost card, such as a regulated debit card, the saving reaches you instead of staying with the processor. See interchange plus vs. tiered pricing, with a cost comparison.
There's no single number, because interchange is the same whichever provider you choose and depends on the cards your customers use. What you're really comparing is the provider's markup: the percentage and per-transaction fee added on top of interchange, plus any monthly fees.
Two checks help. First, get the markup in writing, listed separately from interchange. Second, work out your effective rate: your total fees divided by your total card sales on a recent statement. For a reference point, Authorize.Net's pricing page (checked September 2026) says merchants on interchange plus often pay "closer to 2.2% - 2.5%" overall, compared with its own 2.9% + 30¢ flat rate. Your rate depends on your business and card mix.

Most businesses use a shopping cart plugin. If you're connecting a site yourself, Authorize.Net's current options are: Simple Checkout (buttons, payment links and QR codes, no coding), Accept Hosted (a payment form hosted by Authorize.Net, the smallest PCI scope), Accept.js (your own form, with card data sent straight to Authorize.Net) and the Authorize.Net API for custom builds. SIM, DPM and AIM are deprecated, so a site still using them should plan to move.
See our guide to Authorize.Net integration methods for a comparison and what replaces each legacy method.
