About PrettyDamnQuick (PDQ)

PDQ runs your checkout like a CRO lab. Shoppers get segmented on 1,600+ signals (purchase history, cart size, location, channel, historical behavior). Each segment gets its own checkout, tested head-to-head: shipping rates, delivery promises, upsells, layouts. Winners stay live, losers go back to the drawing board. PDQ's team reviews your data, proposes the tests, and runs them once you approve. Install today, full checkout audit within 3 business days. A/B test the full checkout, not just one widget, even entire themes Per-segment shipping rates, free shipping thresholds, and delivery dates Checkout extensions: upsells, gifts with purchase, trust badges, reviews AI insights: Ask MAXX, your AI helper with full performance data & benchmarks Branded tracking pages, order editing, and post-purchase upsells Show more Show less

Our Checkout CVR is up double digit %'s YoY - Shoutout PDQ team!
— OluKai
PDQ has been our right-hand partner for any revenue-driving or customer experience ideas at checkout. They move fast on every request and consistently bring new ideas and solutions we hadn’t even considered. We saw ROI quickly and they’ve helped us automate processes and build tools that give us much better visibility into our data and checkout experience. Appreciate their focus on the full checko...

PDQ has been an awesome partner and has unlocked some really incredible CRO wins with a material impact on our average revenue per user and overall profitability. I would highly recommend them to anyone looking to improve their DTC performance!
— Clove
Working with PDQ has been a dream. Their checkout optimization and a/b testing are second to none, and their team is always extremely responsive and collaborative. We have seen some great results with them so far and hope to see more to come!
— TheraPetMD
Very detailed and thorough partner for AB testing checkout, shipping, tracking, and overall theme. The analytics that PDQ dives into are far more meaningful and impactful than other AB testing partners we have worked with in the past. Really recommend!
— Grazly
PDQ has become one of our most trusted tools. We've made live changes during our biggest launch of the year, brought in additional revenue, increased conversion, and unlocked personalized experiences for various customer segments. What sets them apart is their team and their approach. Meital and Adi feel like genuine extensions of our own team, proactive with ideas, always testing, and available...

Solid Shopify checkout testing partner PDQ fills a real gap - native A/B testing inside Shopify checkout is hard, and PDQ makes it possible. We've used it at Audien Hearing for header, social proof, and trust signal tests. Our CSM, Meital Wiederhorn, has been excellent. She stays close to our tests, follows up proactively, and jumps in quickly when issues come up. Recommended for Shopify Plus b...
— Audien Hearing
We’ve had a great experience with PDQ so far. We've seen some good results, but what really stands out is how easy they are to work with. Communication has been clear, responsive, and genuinely helpful throughout. One thing I especially appreciate is that the team doesn’t come across as overly “salesy,” which is refreshing compared to a lot of other partners in this space. They focus on what actu...
— Branded Bills
PDQ has been an excellent partner for our growing business. Their customer support team is responsive and genuinely helpful, with Slack support that makes communication fast and easy. They don’t just react to issues—they offer ideas and proactive planning to help set brands up for success. PDQ is the best shipping software we’ve found that allows us to add and accurately ship unlimited SKUs as we...
— Andar
PDQ have really helped us understand different customer segments and how they interact with our checkout. The team are knowledgable, friendly and always responsive which is so helpful. Highly recommend PDQ if you're looking to further understand consumer behaviour and increase conversion across your checkouts.
— Damson Madder
PDQ has been a great partner - a true partner that wants to drive our business as much as theirs. They are truly willing to work side by side and help drive conversion for our site. I was also recently so impressed with their honesty! They truly want to be a partner.
— Thirdlove
We really enjoy working with PDQ. The collaboration feels easy, efficient, and well thought through, and it’s clear the team genuinely cares about delivering value. Danielle is wonderful to work with!
— Qure Skincare
Shady shady shady. The recommendations that the team at PDQ made throughout our engagement were deceptive to customers and didn't adhere to the standards my team and I operate with. When we moved forward with removing their extensions from our site, the company went over my head and reached out to our CFO and co-founders to "tattle" on us for doing so, leading with fear-based tactics about how muc...
— Blueprint Bryan Johnson
Love working with PDQ. It's rare to find an app where the service level is consistently great. Communication is top notch. Highly recommend.
— Cakeworthy
Been a great experience, we've been getting positive tests, and their team has helped make it hands-off.
— Dracoslides
PDQ offers a solid product backed by a responsive, knowledgeable support team. Their tools have assisted us in running A/B tests at checkout and enable delivery scheduling for our customers on time sensitive products. Any time a question or issue comes up, their team is quick to respond and prioritizes great service. We really enjoy working with the PDQ team!
— Jeni's Splendid Ice Creams
PDQ has been useful for running checkout-related tests, including price sensitivity, free-shipping thresholds, upsells, and checkout extensions. We’ve seen steady improvements in both CVR and AOV since implementing it. The team has also been responsive and clear in their communication, which has made setup and ongoing adjustments straightforward. Overall, it’s been a practical addition to our opt...
— Mavi Jeans
PDQ has been an invaluable partner in preparing for BFCM. Their development team moves quickly, their CX support is outstanding, and they’ve worked seamlessly with our highly customized checkout flow as it relates to warranties. They also build custom performance reports that help us make clear, actionable decisions. The team is always willing to jump in and support whenever we need it.
— Groove Life
Great product, super strong team. We've been able to make some material wins on a/b incrementality tests that are dropping meaningful dollars to the bottom line. Tech is great - and this comes from someone who doesn't like SaaS providers in general.
— Made In Cookware Canada
PDQ has been a game-changer for our store. Not only is the functionality incredibly flexible, but their dev team is truly outstanding. They’re fast, responsive, and always willing to customize features or make adjustments that directly improve our conversion and increase shipping flexibility. It’s rare to find an app where support moves this quickly and delivers real, measurable value. Highly reco...
