01 / the trigger
The fee math flipped
The June 1, 2026 Open Payment Provider Fee charges self-serve plans on third-party gateways: Core 2.0%, Growth 1.0%, Scale 0.6%. Shopify Payments waives transaction fees.
Migration / BigCommerce → Shopify Plus
A replatform does not lose your SEO, your orders, or your uptime. A bad replatform does. The platform is not the risk. The execution is, and that is exactly what we own.
Why teams are moving in 2026
On June 1, 2026 BigCommerce re-architected its plans and added an Open Payment Provider Fee on non-embedded gateways. The historic "no transaction fees" pitch reverses for many merchants while Shopify Payments waives them. App ecosystem, admin and total cost have been drifting the same way for years.

02 / the drift
A thinner app ecosystem, a heavier admin, and a total cost of ownership that quietly favors Shopify for most stores once build, processing and apps are counted, not just the platform fee.
03 / the lens
Shopify Plus now does native multi-entity B2B and 2,048 variants per product. The old reasons to stay on BigCommerce have narrowed to a short, specific list.
Products, customers, orders, content. The thing the business runs on, mid-flight between two platforms.
→ a reconciliation line itemEvery URL changes on Shopify's fixed prefixes. Skip the redirect map and organic traffic drops.
→ a 1:1 301 map, loaded before launchThe dread of a storefront down for migration while customers and revenue wait.
→ a DNS cutover, not an outageEspecially B2B pricing logic, quotes, and approvals that took years to tune.
→ carried where it moves, rebuilt where it mustEvery fear on that list is an execution line item, not a platform property. Your data moves cleanly. What we rebuild, and where the value is, is the storefront, your product configurator, and your B2B pricing logic, re-engineered to be more maintainable on Shopify Plus.
The data-migration map
Most records move on a known path. The risk is not the data: it is the four places BigCommerce and Shopify model the world differently. We surface those before the build, not after launch.

DTC and native B2B
Feature parity, honestly
The accurate answer is not "Shopify can do everything." It is a map: better in places, a different model in others, and two real gaps we name rather than bury. That honesty is what makes the rest of the map credible.
The storefront most of your traffic touches.
| Variants per product | 2,048 on Shopify vs 600 SKUs on BigCommerce better |
| Options per product | Still 3 on Shopify; 4+ option products need a combined listing or an app gap |
| Checkout extensibility | Checkout extensions, metaobjects, structured content better |
| Modifiers (file upload, text, date) | No native file-upload modifier; rebuilt with properties or an app different |
| DTC member / logged-in pricing | No native catalog for DTC tiers; rebuilt with Functions or tags gap |
| Multi-storefront / international | Splits into Markets (per country) and Plus expansion stores (per brand) different |
Where the real platform decision is usually made.
| Companies, locations, contacts | Native B2B objects on Shopify Plus parity |
| Contracted catalogs & price lists | Native, with fixed prices, percentage adjustments, volume breaks parity |
| Catalog count | Unlimited on Plus; capped at 3 on lower plans, so Plus is effectively required parity |
| Workflow model | Self-serve contracted-catalog led vs BigCommerce quote-and-rep led different |
| Native quoting | No quote object; rebuilt on draft orders or an app gap |
| Saved lists, invoice portal, masquerade | Quick order lists are native; the rest are app or custom builds gap |
"Shopify can't do B2B like BigCommerce" is false. Shopify Plus does native multi-entity B2B that often fits real B2B better. The difference is the workflow model and a few specific gaps, not raw capability.
B2B, carried vs rebuilt
This is the split that decides a DTC-plus-B2B migration. No migration tool imports catalogs or price lists. Said plainly so nobody is surprised at go-live: done right, the rebuild is an upgrade.
A tooling path exists for everything in this column. It moves on a known route.
Plan this column as a build line, not a migration line. Price data extracts; the catalogs are re-created via priceListCreate.
SEO and redirect preservation
SEO loss is a symptom of skipping the redirect map and the pre-launch crawl. It is not a property of Shopify. An agency that crawls the live store and ships a 1:1 redirect map is the difference between this fear being false and true.
Shopify forces fixed URL prefixes (/products/, /collections/, /pages/) that cannot be edited. BigCommerce's structure is configurable, with Short, Long and Category presets plus custom. For most stores that means every product and category URL changes, so a 1:1 301 map is mandatory, not optional.
We crawl the live store and never assume its URL structure: presets and trailing-slash variants are read off the crawl. We map one-to-one, never many-to-one, because mass redirects read as soft-404s and lose equity. 301s, no chains, held a year, shipped before launch.
Scale is never the constraint. Shopify Plus accepts up to 20,000,000 redirects against 100,000 on standard. And 301s do not lose PageRank: that is Google's own position. Expect a few weeks of fluctuation while Google re-crawls, then recovery.
The de-risk method
We sell the method, not a list of promises. The differentiator is that the whole migration is observable, reversible, and staged. Each phase is a gate with a deliverable; the work moves forward only when the prior gate's evidence checks out.
Count and export everything on the live BigCommerce store: products, variants, customers, orders, existing redirects, and the live URL crawl.
→ the reconciliation baselineAn explicit old-field to new-field map plus an exception list of what will not round-trip cleanly: 4+ option products, modifiers, B2B price lists.
→ the exception listImport into a non-production Shopify Plus store in dependency order: products, then customers, then orders. Orders via API or app, never CSV.
→ the staging storeBoth stores live. Reconcile counts against the baseline and run the full launch-checklist test matrix, including B2B catalog parity. Zero customer exposure.
→ reconciliation report + passed matrixPre-warm DNS to a low TTL a week ahead, take redirects live before the switch, run the final delta sync, then flip the domain. A managed freeze window, not a big-bang flip.
→ redirects-first, delta-synced flipDNS-revert rollback with BigCommerce untouched and exported, never deleted. Verify zero 404s, submit the new sitemap, hold redirects at least a year.
→ verified, reversible, heldClaims you can check
Every myth here is the same failure dressed differently: a property of a careless DIY migration restated as a property of Shopify. Each claim is paired with the deliverable that neutralizes it.
A mishandled replatform loses rankings, not a replatform. Shopify's fixed prefixes change nearly every URL, so a 1:1 301 map, crawled, loaded before launch, and held a year, preserves the equity. 301s do not lose PageRank.

Shopify Plus has native multi-entity B2B: companies, locations, contracted catalogs, volume pricing, quantity rules, net terms, and 2,048 variants per product. The difference is the workflow model plus specific gaps (3 options, DTC member pricing, native quoting), not raw capability.

Near-zero storefront downtime. The new store is built and QA'd on staging while BigCommerce keeps selling. Cutover is a DNS change plus a short final-sync freeze, scheduled in a low-traffic window. Not an outage.

The most dangerous true-sounding claim. The native importer handles products and customers but does not import orders, builds no redirects, and silently drops 4+ option products. That is how you keep the data and lose the business.

Orders migrate with original processed dates and customer links, via a migration app or the Admin API, not the native admin CSV, which cannot import orders at all.

Price data extracts, but catalogs and price lists are rebuilt via the Admin API. There is no Matrixify import path for them. Plan it as a build line, not a migration line.

There is no Shopify quote object to import into. Quoting is rebuilt on draft orders or an app, and the multi-tier approval chain is rebuilt on top of the two per-location roles Shopify provides natively.

True historically for embedded gateways, but the June 1, 2026 Open Payment Provider Fee charges self-serve plans (2.0 / 1.0 / 0.6%) on non-embedded gateways, while Shopify Payments waives fees. The fee advantage reverses for most third-party-gateway merchants.

Tools vs a hand-built migration
Shopify itself ranks "hire a Shopify Partner" and "custom API solution" as its top migration tiers, above CSV and apps. Here is each hard problem, what a tool-only run produces, and what gets owned instead.
The relocation runway
A migration is a relocation: cargo carried gate to gate, reconciled against a counted baseline, with the entities that need hand-shaping visibly diverted, never silently dropped, and a rollback lane back to the source the entire way.
Counts shown are illustrative demo data, not a real client. The point is the shape: every crate carries a count that reconciles against the baseline, nothing is dropped in silence, and the source store is never deleted.
Proof and replatform muscle
We have run legacy and Magento to Shopify Plus replatforms with the exact center of gravity a BigCommerce DTC-plus-B2B move needs: migration integrity at scale, and a B2B pricing and quote engine rebuilt the right way.
Wire America / DWC · Shopify Plus B2BA Shopify Plus B2B build and migration over a 60,000+ SKU industrial catalog. 100% of SKUs were structured, attributed and imported into Shopify.

We have no BigCommerce-source case yet, so the proof is the pattern. For the buyer's number-one fear, the data-migration map and the six-gate redirect method are the substitute proof: migration integrity you can count, not an outcome stat to take on faith.
