According to Shopify research one hour of downtime costs mid-sized and large companies on average more than $300,000 in lost revenue. But even for smaller stores, every minute offline is a minute when your competitor is selling.
The hidden costs of downtime go beyond direct revenue:
In a classic store migration, the following plan is usually followed:
This process easily takes several days to weeks. During that time your store is either offline or running on outdated data. Orders that come in during the migration? They fall through the cracks. Stock that changes? Not synchronised. New customer registrations? Lost.
It's an approach that may have worked in 2015, but in 2026 — with customers shopping online 24/7 and Google continuously evaluating your site — it's simply too risky.
Lightspeed C Series (formerly SEOshop) is a Dutch e-commerce platform that has been a solid choice for online retailers for years. But the e-commerce market doesn't stand still, and more and more merchants are running into limitations:
Recognise one or more of these points? Then it's time to seriously consider a switch.
At Syncer we've developed a fundamentally different approach: Live Sync®. Instead of the traditional export-import cycle, we synchronise data in real time via API connections between Lightspeed C Series and Shopify.
Concretely this means:
| Traditional migration | Syncer Live Sync® |
|---|---|
| Store offline for days | Zero downtime — store stays live |
| One-time data export (snapshot) | Continuous real-time sync |
| Orders fall through during migration | Customers just keep ordering |
| Stock falls out of sync | Stock always up to date on both platforms |
| SEO loss from offline period | Automatic 301 redirects for SEO preservation |
| Weeks of lead time | Smooth transition, you set the timing |
The migration process with Syncer happens in clear steps, without you or your customers noticing anything:
We connect your Lightspeed C Series store to Shopify via secure API connections. Then we synchronise all existing data: products (including variants, images and metafields), customer details, order history and stock levels.
While your Lightspeed store keeps running live, Live Sync® keeps both platforms continuously in sync. A customer places an order on Lightspeed? It appears immediately in Shopify. Stock changes? Both platforms are updated. New customer registration? Synchronised automatically.
While the synchronisation runs, we set up your new Shopify environment. Theme design, installing apps, optimising checkout, connecting payment providers — everything is set up and tested in peace while your current store keeps generating revenue.
When everything is ready and approved, we switch DNS to Shopify. That's literally a matter of minutes. Your customers don't notice anything — they just keep shopping, now on your brand-new Shopify store.
All old Lightspeed URLs are automatically redirected to the right Shopify pages via 301 redirects. That way you keep all the SEO equity you've built up and visitors who arrive via old links just see the right page.
Live Sync® doesn't just migrate data — it keeps everything in real-time sync until you switch over for good:
One of the biggest concerns in a platform migration is the loss of SEO positions. Rightly so, because research shows that downtime can hurt your search positions, and recovery can take weeks to months.
In a Syncer migration we tackle this in three ways:
The result? Instead of weeks of recovery after a migration, you keep your positions and can grow on Shopify right away.
A platform migration isn't a weekend job. It requires deep knowledge of both platforms, experience with API integrations and a proven process that accounts for edge cases you can't predict in advance.
At Syncer we do this every day. As a Shopify Plus Partner, we've guided hundreds of migrations and we know exactly where the pitfalls are. From complex product structures to custom integrations — we make sure nothing gets lost.
You don't need any technical knowledge. You don't have to export CSV files. You don't have to take your store offline. We handle everything while you simply keep on running your business.
