How much you'd save vs BigCommerce.

BigCommerce's themes are forks-and-merge. Mercentia's are sections you edit in the dashboard. Drag the slider to your monthly GMV.

Card processing is excluded on both sides — you pay Stripe either way. This compares what the platform charges on top.

What changes when you leave BigCommerce (especially after June 2026)

The June 2026 fee surprise

BigCommerce added a 2% Open Payment Provider Fee on Core, 1% on Growth, 0.6% on Scale — for PayPal, Klarna, Affirm, Apple Pay, and B2B purchase orders. "No transaction fees" was their loudest argument against Shopify. It's gone.

0% platform transaction fees on every plan, every payment method, including B2B purchase orders. We will never add a surprise transaction fee to existing customers — your rate is locked for the life of your plan.

Forced upgrades on lowered thresholds

"A merchant at $150K annual GMV used to sit comfortably on Plus at $79/mo. That same merchant now sits on Scale at $299/mo. That's a 278% platform cost jump." BigCommerce lowered GMV thresholds in June 2026.

No GMV thresholds. No forced upgrades. You stay on your chosen plan until you decide to upgrade for features.

Core plan loses phone support

"The new Core plan loses phone support entirely. Chat and email remain. If you want to talk to a human at BigCommerce on their entry-level plan, you'll need to pay for an add-on or upgrade to Growth at $105/month."

The AI engineer is your support — reads your orders, integrations, webhooks in context. Real human support is included on Pro+, not paywalled separately.

What carries over

From BigCommerce → Mercentia.

We're upfront about what's lossless, what needs a quick review, and what you'll recreate from scratch. No surprise gaps post-import.

How it works

From "connect" to "live" in under an hour for most stores.

1
Connect
Paste your BigCommerce API credentials. We probe the connection live and report the resource counts (products, customers, orders) before you commit to anything.
2
Preview the diff
See exactly what will be created vs skipped, with the carryover matrix above made concrete to your store.
3
Run the import
BullMQ worker streams the data through. Progress bar updates per phase — collections, products, customers, orders, redirects. Resumable on failure.
4
Test on a preview URL
Your Mercentia store comes up on a *.mercentia.com subdomain. Browse the migrated catalog, walk through a test order, check the redirect map.
5
Cut over
Point your domain at Mercentia. The 301 redirects fire from the old URL shape so customer bookmarks and search engines keep working.
No lock-in

And if it doesn't work out? Take your data and go.

Every product, customer, order and discount exports to CSV on demand — no support ticket, no notice period, no retention call. We do not ship an importer for BigCommerce's exact column shape, so moving on means a mapping step; what we guarantee is that your data leaves with you, in full, whenever you ask.
