Fraud risk audit
Orders, refunds, and disputes from the last 90 days, sorted into fraud, abuse, and customer service causes.
The Problem
Fraud Losses Hide in Your Order Flow
Fraud rarely arrives as one big hit. It shows up as small leaks: a refund you didn't plan for, a dispute you lose, and a good customer your rules turned away.
01 · Shipped fraud
A suspicious order shipped before anyone looked at it.
Borderline orders wait in a review queue instead of shipping.
02 · Card testing
A bot ran hundreds of small card checks overnight.
We add velocity rules and bot defenses against card testing.
03 · Declined buyers
Tighter rules end up blocking loyal customers.
Every rule is tested against your past orders so good customers still pay.
04 · Dispute rate
Your processor emails you about your dispute rate.
A monthly ratio check shows how close you are to Visa and Mastercard limits.
It's Monday, and 3 weekend orders look wrong: different names, one shipping address, cards from 3 countries. One already shipped before anyone looked. The chargeback lands 2 weeks later, with a fee on top of the lost stock. Overnight, a bot ran hundreds of small card checks through your checkout. Then your processor emails about your dispute rate. So you tighten the rules, and next week a loyal customer can't pay. Most stores live here: default settings, one person checking orders by hand, and no idea what fraud really costs.
We start with your last 90 days of orders and disputes to see where fraud gets in. Then we add only the layers your store needs: AVS, CVV, and velocity rules plus bot defenses. A fraud vendor joins only if your volume justifies one. Borderline orders wait in a review queue instead of shipping. We track your chargeback ratio against Visa and Mastercard limits, so fraud gets stopped at checkout, not discovered a month later.
Fewer fake orders shipped
Risky orders wait for a decision instead of leaving your warehouse on autopilot.
Real buyers still get through
We test every rule against your past orders so good customers don't get declined.
A dispute rate you can see
A monthly ratio check shows how close you are to Visa and Mastercard limits.
Our Fraud Prevention Process
From Risk Audit to Tuned Fraud Rules in Five Clear Steps

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built and protected online stores for.
We had been dealing with a frustrating mix of fake orders and legitimate customers getting caught by the same fraud checks. At first, I thought we probably just needed stricter rules, but that actually seemed to make things worse. DeveloperLook took the time to look at how our orders, payments, and customer flow were working together before changing anything. They helped us put a much clearer process in place, and it was a relief to stop treating every unusual order like a problem. We now have a better idea of what needs attention and what can simply move through.
The biggest issue for us was the amount of time our team was spending on questionable orders. Someone would flag an order, then another person would check the address, payment details, phone number, and sometimes even contact the customer. It became part of the daily routine, especially when order volume picked up. DeveloperLook helped us rethink that process and put clearer checks in place before an order reached our team. What I liked most was that they didn’t just recommend a tool and leave us to figure it out. They actually worked through the setup with us and explained why each part was there.
We were becoming a little too cautious with our checkout because we had already dealt with a few bad orders. The problem was that our genuine customers were starting to feel some of that caution too. I remember looking at an order from a returning customer and wondering why we were making the process so difficult for someone we already trusted. DeveloperLook helped us look at the bigger picture instead of simply adding more verification steps. The whole thing felt much more balanced afterwards. We still take fraud seriously, but we’re not making every customer jump through hoops just because a few risky orders came through before.

Work Culture
Why Store Owners Trust Us With Their Checkout
These habits run through every fraud setup we deliver. Rules come from your own data, and each change is tested on your past orders before customers see it.
Your orders set the rules
We keep fraud prevention ecommerce-specific: rules come from your own orders, refunds, and disputes. Every rule traces back to a loss your store has actually had.
Good buyers tested first
Before a rule goes live, we replay your past orders through it. If it would have stopped loyal customers, we change it before launch.
Defense in layers
AVS, CVV, velocity limits, and review each catch a different attack. We stack them so one gap doesn't cost you a month of chargebacks.
Card network ratios watched
We check your dispute ratio against Visa and Mastercard limits every month. You hear about a rising rate from us, not from a processor warning.
People decide the close calls
Borderline orders go to a person with every signal on one screen. Your team makes the call, and we adjust the rules from their decisions.
Fixed price before we start
You approve the rule plan and a fixed price after the free audit. If your platform's built-in tools already cover you, we'll tell you before we quote.

Good fit
Stores hit by fake orders and bots
You're refunding stolen-card orders every week. Bots also test cards through your checkout at night, piling up decline fees and disputes.
Stores nearing a processor warning
Your processor has flagged your dispute rate, and you need to know how close you are to the Visa and Mastercard monitoring limits.
Teams stuck checking orders by hand
Your team checks every large order by hand, and it no longer keeps pace with order volume during sales and holiday peaks.
Stores on default gateway settings
You rely on your gateway's default fraud settings, and organized fraud still gets through while some good customers get declined.
Ecommerce agencies with client stores
Your clients ask for fraud help, and you want a white-label partner who sets up rules and review steps under your brand.
Not a fit
Custom scoring code
You need custom scoring code for a headless or marketplace checkout. Our Ecommerce Fraud Detection Development service builds that engine from scratch.
Shopify tools only
Your store runs only on Shopify and you just want its built-in tools set up. Our Shopify fraud setup service is the smaller, cheaper fit.
Disputes already landed
The chargebacks have already landed and you need them disputed. Our Chargeback Management Services team handles evidence and representment, which this setup doesn't cover.
Few orders, no fraud yet
You get a handful of orders a month and no fraud yet. Your platform's free settings are enough for now, and a $900 setup would be overkill.

Our fraud setup starts at $900 for AVS, CVV, velocity, and card testing rules on the tools you already use. Adding a fraud vendor and a review routine costs $2,000, and multi-gateway programs with reporting start at $4,500. Vendors like Signifyd charge their own fees, usually a share of each approved order. You get a fixed quote after the free audit.
Setup takes 1 to 2 weeks when we tune the tools you already have. Adding a fraud vendor and a review step takes 2 to 3 weeks, and multi-gateway programs take 3 to 5 weeks. Most of that time is testing. We replay your recent orders through every new rule, because a bad rule declines real customers on day one.
Look at several signals together, not one red flag. Fake orders often combine a billing and shipping mismatch, a brand-new email, a proxy or distant IP, rushed shipping, and several cards tried within minutes. Real customers trip single signals all the time, like a gift sent to another address. So we write rules that act on combinations and send the close calls to review.
Most stores need neither at first, because tuned platform rules stop the common attacks. Ecommerce fraud prevention software like Signifyd, NoFraud, or Riskified pays off once losses or review hours grow. These vendors cover fraud chargebacks on the orders they approve, for a share of each approved order. Unusual catalogs or checkouts need custom logic, which our fraud detection development team builds.
A fraud score rates each order the moment it's placed, and your rules act on that score. Low-risk orders go straight to fulfillment, the riskiest get cancelled and refunded, and the middle band waits in a review queue. There, a person checks the signals, contacts the buyer if needed, and approves or cancels the order before anything ships.
Each check catches a different misuse of stolen card data. AVS compares the billing address with the bank's records. CVV shows the buyer has the full card details, and velocity limits cap attempts per card, email, or IP in a short window. None is enough alone, so we combine them and send the mismatches real customers cause to review.
Stop card testing with layers: a CAPTCHA before payment, rate limits per IP and session, and rules that block repeated small attempts. Stripe's own guidance notes that single filters, such as IP blocks, usually aren't enough on their own. On Shopify Payments, card testing protection is built in, and we add rules on top. We also refund test charges that slip through before they turn into disputes.
Track your ratio every month and act well before the card network limits. Visa's VAMP rules flag merchants in the US, Canada, and Europe at 1.5% fraud reports plus disputes against card-not-present sales. That applies once they reach 1,500 fraud reports and disputes a month. Mastercard flags 1.5% with at least 100 chargebacks. Acquirers face stricter portfolio limits, so we set your internal alert near 0.5%.
They shouldn't, and we test to make sure. Most checks run quietly in the background, so shoppers see no extra steps. The checks that add friction, like a CAPTCHA or 3D Secure, only trigger on risky sessions. Before launch, we replay your past orders and count how many good customers each rule would have stopped.
You keep every rule, list, and review checklist we build, documented in plain English. We tune thresholds for 30 to 90 days depending on your plan. Then we hand over a short monthly routine your team can run. If fraud patterns shift later, we can quote a tune-up, but most stores run the setup on their own.
