LET'S DISCUSS
We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.

The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
James Whitmore
Head of Marketing of Lumen Outdoor
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

07Work Culture
Why Merchants Trust Us With AVS
A blunt AVS rule rejects honest customers with typos, so we tune each response code. These are the habits we bring to AVS address verification system setup.
Rules by response code
Full mismatches decline, partial matches go to review, full matches clear.
Fewer honest declines
Real address validation fixes typos before payment.
Layered protection
AVS works alongside CVV and velocity checks.
Gateway-specific setup
We adapt to how your gateway reports AVS results.
Tested with real orders
We check the rules against real transactions.
Quick to deploy
Most setups finish within one to three weeks.
08Overview
What is an address verification system, and do AVS mismatches mean an order is fraud?
An AVS mismatch doesn't mean fraud. Recently moved customers, browser autofill pulling old addresses, international cards outside AVS-supported regions, and gift orders shipped elsewhere trigger mismatches, while a criminal with a stolen card and correct address passes AVS fully. We configure risk-tiered rules: full mismatches decline, partial matches review, full matches clear, and layer CVV and velocity checks. Starts from $999.

Who it's for
Stores declining every AVS mismatch
You're losing good orders because a partial or system-error AVS code is treated the same as a full mismatch.
Stores with international customers
Cards from outside AVS-supported regions return system errors that get mishandled as fraud signals.
Stores wanting address validation before checkout
You want typos and formatting issues caught before payment, not after.
Stores relying on AVS alone
You don't have CVV or velocity checks layered on top, so a stolen card with the correct address slips through.
Stores wanting mismatches routed to review
You want a human decision on partial matches instead of an automatic accept or decline.
Not a fit for
You need the full layered fraud prevention stack, not just address verification. Our Ecommerce Fraud Prevention Services page covers that broader scope.
You want cardholder authentication with liability shift, not address matching. Our 3D Secure Implementation page covers that.
You need chargeback-specific prevention, not checkout-level address checks. Our Chargeback Prevention Services page covers that.

What is an address verification system (AVS)?
AVS checks whether the billing address a customer enters matches the address on file with the card issuer, returning a match, partial match, or mismatch code.
How do AVS and CVV checks reduce fraud?
AVS confirms the billing address matches the card issuer's records, and CVV confirms the buyer has the physical card, together making it harder for stolen card details alone to pass checkout.
How do I set AVS rules on my payment gateway?
We configure risk-tiered response rules on your gateway so full matches clear, partial matches route to manual review, and full mismatches decline.
Do AVS mismatches mean an order is fraud?
No. Recently moved customers, browser autofill pulling old addresses, and international cards outside AVS-supported regions all trigger mismatches on legitimate orders, while a criminal with a stolen card and correct address can pass AVS fully.
How do I add address validation at checkout?
We add real-time address validation that catches typos and formatting issues as the customer types, before the order ever reaches payment processing.
How do velocity checks work with AVS?
Velocity checks cap how many attempts a single card or IP can make in a short window, catching patterns AVS alone would miss since AVS only evaluates one order at a time.
How much does AVS and address validation setup cost?
Starts from $999, scaling up depending on how many response code rules and additional checks you want layered in.
Can mismatched orders go to a manual review queue?
Yes, we route partial AVS matches to a review queue rather than an automatic accept or decline, so a person makes the final call on borderline orders.
