Trusted Payment Processing Solutions for Every Business

Payment processing is the backbone of modern commerce. Every time a customer taps, dips, swipes, or types a card number, an intricate chain of events moves money from the customer's bank to yours in seconds. Understanding how this process works empowers you to choose the right processing partner, negotiate better rates, and avoid the hidden fees that erode your profit margins.

The Payment Processing Lifecycle

A credit card transaction involves four parties: the cardholder (your customer), the merchant (your business), the issuing bank (the bank that issued the customer's card), and the acquiring bank (the bank that provides your merchant account). The payment processor and payment gateway act as intermediaries, routing data between these parties. When a customer presents their card, the terminal or gateway captures the card data, encrypts it, and sends an authorization request through the card network to the issuing bank. The issuing bank verifies the account, checks for available funds, and runs fraud screens before returning an approval or decline code — all within about 1 to 3 seconds.

Authorization, Batching, and Settlement

Authorization is just the first step. At the end of each business day (or more frequently, depending on your settings), your terminal or POS system sends a batch of all authorized transactions to the processor for settlement. The processor routes each transaction through the card networks, which instruct the issuing banks to transfer funds to your acquiring bank. Your acquiring bank deposits the net amount (sale amount minus processing fees) into your business bank account. With next-day funding from Unison, you typically receive your funds by the following morning. Same-day funding is available for qualifying merchants who need immediate access to their sales revenue.

Choosing the Right Processing Model

There are three common pricing models in the payment processing industry, and the one you choose directly affects your bottom line. Flat-rate pricing (used by Square, Stripe, and PayPal) charges a fixed percentage like 2.6% + $0.10 on every transaction regardless of card type. Tiered pricing (used by many legacy processors) bundles transactions into qualified, mid-qualified, and non-qualified tiers — which sounds simple but often results in most transactions falling into the more expensive tiers. Interchange-plus pricing (what Unison offers) passes through the wholesale interchange rate set by Visa and Mastercard and adds a small, transparent markup on top. For businesses processing more than $5,000 per month, interchange-plus pricing almost always results in the lowest total cost.

What Sets Unison Apart

Unison Payment Solutions was built specifically for small and mid-sized businesses that deserve the same transparent pricing and dedicated service that large enterprises receive. Unlike aggregators that put thousands of businesses under a single merchant ID — risking sudden holds and account terminations — Unison provides every merchant with a dedicated merchant account, a dedicated account manager, and direct access to our support team. We specialize in both standard and high-risk industries, meaning we can serve businesses that other processors turn away. Our underwriting relationships with multiple acquiring banks allow us to match each merchant with the bank that offers the best rates and terms for their specific business type and processing volume.

Beyond transparent pricing, Unison provides a complete payment ecosystem: POS hardware from industry-leading brands like Clover, PAX, and Dejavoo; a PayTrace-powered payment gateway for eCommerce and card-not-present transactions; a cash discount program that can eliminate your processing fees entirely; consumer financing through Affirm, Afterpay, and Klarna to increase your average order value; chargeback prevention tools to protect your merchant account; and advanced analytics and CRM integrations to help you understand and grow your business. Getting started is straightforward — complete a brief application, receive approval in as little as 24 hours, and start accepting payments within days.

Switching payment processors sounds daunting, but with Unison Payment Solutions, the transition is designed to be seamless with zero downtime for your business. Many business owners stay with overpriced or underperforming processors because they fear the switching process will be disruptive — but in reality, the process takes a few days and your customers will never notice the change.

Here is how the transition works: First, we analyze your current processing statement and identify every fee you are paying. Second, we set up your new merchant account with Unison — typically approved within 24 to 48 hours. Third, we configure your equipment — if you are using compatible terminals, we can reprogram them; if you need new equipment, we ship it pre-configured to your location. Fourth, we perform a parallel testing period where your new Unison account is live and processing alongside your existing account. Once you confirm everything is working correctly, we help you close or cancel your old account.

For eCommerce businesses, the gateway transition is just as smooth. We configure your PayTrace gateway credentials, update your website checkout integration, and test transactions in our sandbox environment before going live. For businesses with recurring billing, we handle the migration of customer payment tokens (when possible from your existing gateway) to minimize the need for customers to re-enter payment information. Our dedicated account managers guide you through every step and are available by phone whenever you have questions.
