The #1 reason commerce replatforms blow up isn’t the technology. It’s the product data, customer records, and pricing logic nobody cleaned up first.
I sat across from a VP of Digital at a mid-market retailer last year. She opened the meeting with five words: “We need a new platform.”
I’ve heard that sentence dozens of times over twenty years of building commerce sites. The details change (the checkout breaks in weird ways, the mobile experience is embarrassing, the dev team spends 80% of its time on workarounds) but the frustration is always the same. The person saying it is almost always right that something has to change.
They’re focused on the wrong part of the problem.
The Demo Runs on Perfect Data. Your Business Does Not.
Every commerce platform on the market has an incredible demo. Beautiful product pages, slick checkout, AI recommendations that feel like magic.
The demo is designed to make you say yes. And it works. I’ve watched teams fall in love with a platform in a 90-minute pitch and spend the next year trying to figure out why their site looks nothing like the demo room. Same platform. Same features. Completely different result.
The difference is the data. The demo has 200 perfect SKUs with complete attributes, clean images, and consistent pricing. Your catalog has 15,000 SKUs and nobody can tell you how many have complete descriptions.
The Unsexy Truth
The number one reason commerce replatforms run over budget, over timeline, or flat-out stall is the data underneath the technology.
Your customer data lives in three systems that don’t agree on what a “customer” is. Your pricing rules are in a spreadsheet that one person understands. Your inventory feed refreshes once a day, but your website promises real-time availability.
None of this shows up in the demo. All of it will wreck your timeline if you don’t deal with it before you write a single line of new code.
What Separates the Projects That Ship
After twenty years of building commerce (and being responsible for quite a few projects that didn’t go smoothly), I keep coming back to the same patterns.
Data readiness before platform selection. Don’t pick a platform and then figure out your data. Audit your catalog, your customer records, and your pricing logic first. Know what you’re working with. If 40% of your product data is incomplete, no replatform will fix that. That’s a data problem, and it needs to be solved on its own terms.
Process change before go-live. A new platform doesn’t change how your team works. It gives them a nicer interface to do the same broken things. I worked with a distributor who spent $500,000 on a new storefront and watched their operations team bypass it within the first month. Nobody had changed the fulfillment workflow. The warehouse team went right back to adjusting inventory in their spreadsheets.
Scope that proves value in weeks, not quarters. The full vision is 18 months. The first proof of value should be 12 weeks. Pick the one workflow that causes the most pain and fix that first. Ship something your team can point to and say “this is better” before you tackle everything else.
That last point matters more than people think. It’s how you keep your executive sponsor engaged past month three.
The Catch
Replatforming isn’t cheap. Salesforce Commerce Cloud, Shopify Plus, Adobe Commerce: none of them are free, and the licensing is only part of the cost. Implementation, data migration, integration work, training. These add up fast.
And if your data isn’t ready, the cost multiplies. Every week your team spends cleaning product records during implementation is a week the project slips. I’ve seen projects double their original timeline because nobody budgeted for data cleanup. The client thought they were six months from launch. They were fourteen months away, and the gap was entirely data quality.
The honest move is to scope the data work before you scope the platform work. Less exciting. No cool demo. But it’s what separates a project that launches from one that dies in staging.
Start With the Boring Stuff
If you’re thinking about a commerce replatform, or you’re in the middle of one that isn’t going well, step back and ask three questions:
- Is your product data complete enough to power the experience you’re promising?
- Have you changed the internal processes, or did you just swap the technology?
- Are you trying to ship everything at once, or proving value in stages?
If the answer to any of those is “no” or “I’m not sure,” that’s where the work starts. Not in the platform selection meeting.
At Ateko, we help commerce teams get honest about where they are before we talk about where they’re going. Sometimes the answer is a new platform. Sometimes it’s fixing what’s underneath the current one first. We’d rather tell you the truth upfront than hand you a bill for a project that was never set up to succeed.
