Retail Payment Processing Solutions

Retail Payment Processing Solutions

When registers are slow, customers have time to reconsider the sale. E-Complish connects a retail payment processing solution directly to the POS system you already run, so card, ACH, and wallet payments clear in seconds and the sale closes before anyone changes their mind.

25 Years of Optimizing Retail Payments

Retail changes fast, and E-Complish has kept up with it for over two decades. We help retailers optimize their payment systems, enhance security, and create frictionless checkout experiences that strengthen customer loyalty.

Here’s how we bridge the gap between your POS system and modern payment processing:

Unified Commerce

A sale that starts online and finishes at the counter still shows up as one transaction in your reporting, not two. In-store, online, and mobile all run through the same platform, so nothing gets lost between systems.

Enhanced POS Functionality

Get more out of your POS by adding payment processing that covers diverse payment types, recurring billing, and detailed reporting. The upgrade happens on the payment side, not the equipment your staff already knows how to use.

Unwavering Security

Protect your business and customers with our PCI DSS 4.0.1, Level 1 compliant platform, the highest tier of card-data security certification. That protection doesn’t just cover one channel; it covers the online checkout and the in-store terminal equally.

Tailored Solutions

Our payment solutions for retail fit into your existing POS system and workflows without forcing a rebuild. Custom checkout flows and branding carry across every channel your customers use to pay.

Faster Settlement, Clearer Reporting

Recurring billing and daily transaction summaries give you a predictable read on cash flow instead of a surprise at month’s end. Reports can be segmented by location, register, or transaction type, eliminating the need for manual reconciliation across multiple retail locations.

Every Payment Type Shoppers Already Use

Card, ACH, mobile wallet, and cash-equivalent options all run through the same system, so a customer’s preferred way to pay is never the reason a sale falls through. Adding a new payment type later doesn’t mean replacing the equipment already at the register.

Your Payments Should Work as Hard as Your Sales Floor

With E-Complish, your payments infrastructure is a strategic advantage, not a back-office cost center. Support your offerings with a payment gateway that’s secure, reliable, and easy to use.

The E-Complish team helped us decrease our delinquencies by 15% and increased our online payments by 80%!! I cannot say enough about how this team works with us to analyze the problem and provide a solution. Not once did they try to upset us on a product that we did not need. I consider E-Complish a partner and consultant, not just a vendor.

E-Complish set the standard for what U.S. Auto Credit expects of its vendors. E-Complish has brought together a group of professionals that have created a partnership with U.S. Auto Credit, and provide a level of support one expects of full-time hires. Their knowledge of collection practices, card processing and software development has furthered our collection activities, while promoting profitability and decreasing collectors’ talk time. I am a self-professed fan of E-Complish, and I would not hesitate recommending E-Complish for any job they solicit.

Your company came up in a discussion here the other day. They were discussing different E-Complish APIs than E-Complish offers. I told them to be nice to you because your group always does an excellent job for us. One of the other people in the discussion agreed. He said something along the lines of wanting to kick most vendors but he was very positive about working with E-Complish. Thanks, all. You are appreciated!

Since bringing E-Complish into the fold as our overall payment processor we have experienced little to no problems with processing while reducing our cost by over 30%. They are quick to respond to any question or problem that we have and do a great job of keeping informed as to the ever changing world of electronic payments. I would highly recommend E-Complish as a payment processor as they will streamline your processes and take many of the headaches out this necessary business application. I checked off the three attributes but could easily make a case that our relationship with E-Complish has been personable, they have vast expertise in this area, they produce the files in a timely manner every time, and they also operate with the highest amount of integrity. I don’t give recommendations lightly as a matter of business practice but this is one I have no problem giving. These guys do a great job!

Frequently Asked Questions

How does E-Complish handle chargebacks and disputes?

Our system uses fraud detection and analysis to flag disputes early, then our team pulls original sales documentation to challenge invalid claims. Reports organize transactions by date, type, or status and export cleanly into your accounting system, making it easy to identify and resolve issues before they become chargebacks.

Can I customize the look and feel of the payment process to match my brand?

Yes. You control the checkout's colors, logo, custom fields, and messaging, so it reads as your store rather than a third-party processor's page. That branding carries across both your online portal and in-store terminal, so customers get the same look whether they're paying on your website or at the counter.

What level of support can I expect from E-Complish?

Our in-house team is available 24/7, from initial setup through ongoing troubleshooting, so a payment issue doesn't have to wait for business hours. You handle running your store; we handle the technical side, like reconciling a failed transaction or updating a payment method.
