Requirements document
What your store must do, written down and ranked, so every vendor and team quotes the same scope.
The Problem
Everyone Has an Opinion on Your Next Platform, but Nobody Has Numbers
It shows up at renewal time or after a slick vendor demo. Replatforming ecommerce stores goes wrong when the platform comes first and the requirements come later.
01 · Opinions
Everyone has an opinion on your next platform, but nobody has numbers.
Your must-haves are written and ranked before anyone watches a demo.
02 · Hidden costs
A vendor demo looked great, but the costs stay unclear.
Plan fees, apps, hosting, and upkeep are compared for each candidate.
03 · Lost traffic
Stores lose traffic after launches that skipped SEO planning.
Every old URL gets a redirect target before the new store is built.
04 · Wrong pick
Picking wrong costs you twice, once to move and once back.
If staying put is the better call, the report says so.
Your renewal quote is on the table, and a vendor demo looked great last week. Your developer says the current store just needs an upgrade. Everyone has an opinion, and nobody has numbers. You've heard the stories too: traffic that fell after launch, wholesale buyers who couldn't log in, a budget that kept growing halfway through. Picking wrong costs you twice, once to move and again to move back.
We start with your requirements, not a platform. We list what your store must do, score 3 candidate platforms against that list, and price 3 years of fees, apps, and hosting for each. You get a recommendation, a data and SEO plan, and a fixed quote for the move. If staying put is the better call, the report says so instead of selling you a build.
Requirements come first
Your must-haves are written and ranked before anyone watches a platform demo.
Total costs, not first invoices
Plan fees, apps, hosting, and upkeep compared across the years you will run the store.
SEO planned before building
Every old URL gets a redirect target before the new store is built.
Our Replatforming Process
From First Call to Your New Platform in Five Clear Steps
You see the requirements, the scorecard, the cost comparison, and the migration plan before you commit to any build work.
We talk through your pain points, growth plans, and budget, and look at your current store. You learn whether a full assessment is worth it. If an upgrade or a cleanup fixes the problem, we'll tell you before we quote.
What's Included
What's Included, From the Ecommerce Replatforming Checklist to Launch

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built and relaunched ecommerce stores for.
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.
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.

Why Store Owners Trust Us With Their Platform Decision
A platform choice shapes your costs for years. These habits keep the decision grounded in your numbers, whichever platform wins.
Requirements before demos
We write down what your store must do before anyone watches a platform demo. Vendors then answer your list, not their script.
Costs counted beyond year one
We price fees, apps, hosting, and upkeep over 3 years, not just the first invoice. A cheap license with expensive apps shows up early.
Staying put stays an option
Every assessment scores your current platform next to the new ones. If an upgrade beats a move, the report says so plainly.
B2B rules mapped first
Company accounts, price lists, and payment terms get mapped before we compare platforms. That way, your wholesale buyers shape the choice.
Fixed quote after assessment
The assessment ends with one fixed quote for the move, priced on your real requirements. Anything new gets quoted before we build it.
You keep every document
The requirements, scorecard, cost model, and plan are yours, even if another team builds. Nothing in the assessment locks you to us.
Overview
How does ecommerce replatforming work from start to launch?
DeveloperLook provides ecommerce replatforming services that start with the decision, not the build. We document your requirements, score 3 platforms, and compare 3-year costs, then plan and run the move with redirects and integrations. Assessments start at $550 and take 2 to 3 weeks, and a full move usually launches within 6 to 14 weeks.

Good fit
Stores facing a platform renewal
Your platform contract renews next quarter, and you want a real cost comparison before you sign for another term.
B2B sellers outgrowing their platform
You're planning a B2B ecommerce replatforming and need company pricing, payment terms, and ERP sync mapped before anyone picks a platform.
Teams split between two platforms
Your team is split between Shopify and BigCommerce, and you want an outside score built on your own requirements.
Owners who want an outside view
You want a consultant who scores platforms on your numbers and hands your board a report it can actually read.
Agencies advising a client
Your agency's client asked which platform to move to, and you want the assessment and build done under your brand.
Not a fit
Shopify already chosen
You've already chosen Shopify and only need the move done. Our Shopify Migration Services page covers that with set prices.
Data move only
Your platform decision is made and you need data moved between two systems. Our Ecommerce Migration Services page runs that managed move.
Speed or design fixes
Your store works and only needs speed or design fixes. A theme update or speed work costs far less than a platform move.
Recently launched platform
Your budget is under $550, or your current platform went live less than a year ago. Revisit the question when your renewal gets closer.

The checklist covers 7 areas: requirements, platform choice, total cost, data, integrations, SEO, and launch. Requirements come first, because every later decision depends on them. Data covers products, customers, orders, and subscriptions, while SEO covers redirects, metadata, and a watch period after launch. Every plan includes a written checklist for your store.
It's time to replatform when fixing your current platform costs more than moving, or when it blocks something you need to sell. Common triggers are a large renewal or upgrade bill, B2B needs it can't meet, slow pages you can't fix, or a vendor ending support. If an upgrade solves it, stay where you are.
Replatforming with us starts at $550 for the assessment alone, or $2,900 and $6,800 with the move included. The $550 plan scores 3 platforms and compares 3-year costs. The $2,900 plan adds the move for a store up to 5,000 products. The $6,800 plan covers B2B stores with price lists and an ERP connection.
Choose the platform that meets your ranked requirements at the lowest 3-year cost, not the one with the best demo. We score Shopify, BigCommerce, WooCommerce, and Adobe Commerce against your catalog, B2B rules, integrations, and team skills. Then we price fees, apps, hosting, and upkeep for each option.
The assessment takes 2 to 3 weeks, and a full replatform takes 6 to 14 weeks from the first call. A standard store is usually live in about 8 weeks. B2B stores with ERP connections run toward 14, because wholesale buyers test their price lists and terms before launch.
You avoid losing traffic by planning SEO before the build starts. Redirect every old URL to its closest match, keep titles and copy, and launch with a checked sitemap. Rankings can wobble for a few weeks while Google recrawls, which its own guidance calls normal. We track Search Console daily through that period.
Yes, and B2B moves need extra mapping before any data moves. Company accounts, price lists, payment terms, and quick-order tools each need a home on the new platform, and your ERP has to keep sending prices and stock. We check which B2B features each candidate platform offers natively and which need an app.
Our quote covers the assessment, the migration plan, the build, the data move, redirects, and 30 days of support, each on its own line. Platform subscriptions, paid apps, and new photography sit outside it, and the quote says so. You receive it after the assessment, priced on your real requirements.
A replatforming consultant turns your requirements into a platform decision, a cost comparison, and a migration plan your team can act on. We also build the move, so the plan and the launch come from the same people. If you only want the assessment, the $550 plan stops there.
For 30 days after launch, we watch rankings, 404s, orders, and integrations, and fix any problems in that window at no charge. At day 30 you get a short review comparing results with the plan, including traffic and running costs. Ongoing work after that is optional and quoted separately.
