“Another great project done by OUXP. The new bundle page is amazing! We have many many orders from this page and customers love this.”
What merchants say most often
Four things keep coming up in the reviews below. Under each point are the stores that say it.
-
We finish work other developers couldn’t
Another developer said it couldn’t be done, or tried and didn’t finish – then we delivered. Reviewers name a central inventory system for a custom setup, a Recharge problem solved in a day, custom code fixed and matched to the original Figma design, and complex theme fixes.

Quick replies and fast fixes
Many reviews talk about communication as well as the code: quick responses, smooth communication, good follow-up, a mobile announcement bar fixed in 30 minutes before a Halloween promo, a Recharge problem solved in a day. Those were single jobs; what we commit to is an engineer’s first response within 30–60 minutes during business hours.

Results merchants could see
Many orders from a new bundle page, a clear bump in conversions, a new theme that beat the old one in an A/B test, and speed scores of 90+ on mobile – as the merchants themselves report them. Measured results like these are what our Shopify conversion rate optimization work aims for.

“We have worked in numerous developers over the years… We have had some complex needs on our site, where other developers have said it could not be done. ‘Outstanding Experience’ has been able to get it done every time.”
About this project
A trade-only wallcovering studio that prints in-house. It needed gated trade accounts with application and approval, member-only per-square-foot pricing, free sample orders and a pipeline for custom pattern requests. We built that trade channel on Shopify – read the Wall Snobs case study.

“We brought in OUXP for some CRO fixes and theme/app compatibility issues, and they absolutely overdelivered. They didn't just patch things - they tracked down the real root causes, cleaned up our theme and got all the key apps working together smoothly. The store works faster, more solid, and we're seeing a clear bump in conversions.”

Where to check these reviews yourself
Two public records, kept by the platforms rather than by us. Both are worth a look before you hire any agency, including this one.

Shopify Partner Directory
Shopify’s own directory of partner agencies. Our listing holds all 263 reviews – the ones quoted here and the ones we didn’t pick. It also shows our partner status: Shopify Plus Partner since 2019.

Honest note
This page is a selection, and we chose the quotes – copied word for word, never reworded or completed, with our own notes labeled “About this project”. The directory keeps the full record: every published rating, good or bad, posted by the merchant and not editable by us. If you want the whole picture, read it there.
Questions about our reviews
Want to talk to the team the reviews describe? Ask an engineer – first response within 30–60 minutes during business hours (Mon–Fri, 9 AM–9 PM ET).
Where do OUXP’s reviews come from, and are they edited?
Every quote on this page comes from OUXP’s listing on the Shopify Partner Directory, where only merchants who have worked with a partner can leave a review. We quote the merchant’s words without rewording them, emoji included, and shorten long reviews to an excerpt: the cut is marked with “…”, and we never add words or finish a sentence the merchant didn’t. Notes marked “About this project” are written by OUXP and kept separate from the merchant’s words.
What is OUXP’s rating?
OUXP is rated 4.9/5 from 263 reviews on the Shopify Partner Directory (external site) and has been a Shopify Plus Partner since 2019. Separately, our Upwork agency profile (external site) – under our full name, Outstanding Experience – is Top Rated with 100% Job Success across 177 jobs. The two are independent records, so we never add their counts together.
Many reviews say “he” – is OUXP one developer or a team?
A team. Merchants often write to the engineer they worked with day to day, so some reviews use a first name or “he”. Everyone named is part of the OUXP team, and we quote those reviews unchanged rather than edit the names out. Projects run as team work: a senior engineer reviews every change before it reaches your store.
Why do some reviews say “Outstanding Experience”?
Outstanding Experience is OUXP’s full name. Some merchants use it in their reviews – Wall Snobs, for example – and our Upwork agency profile is listed under it. It is the same company and the same engineering team, so reviews under either name describe work by the people who would work on your store.
Do you have reviews for platform migrations, such as Magento to Shopify Plus?
Not many, and none of the reviews quoted here names Magento or another ecommerce platform as the starting point. Lordstown Motors reviewed a store migration to Shopify: “Store migration is successfully done by a top-notch team on Shopify.” Michelle Farmer moved from QuickBooks POS to Shopify across multiple stores, and NEODERMA / The White City was a brand migration. Most directory reviews describe work on stores already on Shopify. For a move off Magento or Adobe Commerce, our migration pages publish the process in seven steps – from discovery and mapping to a pilot import reconciled against the old store, a launch rehearsal and post-launch monitoring: see how a Magento migration runs and how an Adobe Commerce migration runs. Or get a free migration assessment of your own store.
Is OUXP really as quick to respond as the reviews say?
Reviews mention a fix in 30 minutes and a Recharge problem solved in a day – those were individual jobs, not a promise. What we commit to is a first response from an engineer within 30–60 minutes during business hours (Mon–Fri, 9 AM–9 PM ET) for every request. Outside those hours the emergency line stays open: clients with 24/7 coverage get a 2-hour first response, and one-time requests are answered as engineers are available, so call rather than email. See emergency support.
Which brands has OUXP worked with?
Merchants who have reviewed OUXP on the Shopify Partner Directory include True Classic, FANGORIA, Lordstown Motors, Säker, Wall Snobs, Tiger Tool, Pet Wellness Direct and DipYourCar.com. Our case studies cover CleanFlow and Wall Snobs in more depth. We show store names as text, not logos, because a logo suggests an endorsement we haven’t asked the brand for.

Tell us what your store needs – a hard fix, a migration or engineers on call every month. An engineer replies within 30–60 minutes during business hours.
