BigCommerce to Shopify is the most-executed ecommerce platform migration of 2026. The drivers are familiar at this point: BigCommerce’s pricing changes, Shopify Plus’s feature maturation, the app ecosystem gap between the two platforms. What’s less commonly discussed is how much the agency market has consolidated around specialists who do this specific move well.
The top 10 BigCommerce to Shopify migration partners below share a profile. They’ve done the BigCommerce-to-Shopify work enough times to have recognized the patterns. They know which BigCommerce quirks will cause delays and which are minor. They can tell you, during scoping, what your project will actually cost and how long it will actually take. General Shopify agencies can do the migration. Specialists do it without drama.
How this was ranked
We scored on Shopify Plus Partner tenure, BigCommerce-specific source experience (not just general Shopify capability), in-house team depth, and documented BigCommerce-to-Shopify case study coverage. We favored agencies with deep BigCommerce experience over agencies with broad platform reach, because BigCommerce’s specific quirks (category hierarchy, custom fields, API structure, app ecosystem) require pattern recognition that only comes from repetition.

Picking by source complexity
BigCommerce migrations vary dramatically based on the source store’s profile. A simple DTC BigCommerce store under 5,000 SKUs is a very different project from a BigCommerce Enterprise B2B installation with 50,000 SKUs, company account pricing, and multi-brand multi-store configurations.
For simple BigCommerce DTC stores, the agency shortlist can include mid-market specialists with packaged pricing. Look for agencies that offer 8 to 12 week delivery and $15,000 to $30,000 pricing for this profile.
For BigCommerce Enterprise merchants with B2B, multi-store, or custom checkout requirements, the shortlist narrows to enterprise Shopify Plus specialists who’ve done BigCommerce Enterprise exits before. Look for agencies that can talk specifically about company account migration, price list mapping, and Shopify Plus B2B configuration.
For BigCommerce merchants with heavy custom app dependencies, add agencies with documented app-rebuild experience to the shortlist. This is the profile where “general Shopify agencies” most commonly fail to deliver on time.
Questions BigCommerce merchants keep asking
How long does a BigCommerce to Shopify migration take? The honest answer is 8 to 24 weeks depending on complexity. Simple BigCommerce DTC migrations: 8 to 12 weeks. Mid-market BigCommerce with custom features: 12 to 18 weeks. Enterprise BigCommerce Plus projects with B2B or multi-store: 16 to 24 weeks. Anyone quoting faster without a specifically simple scope is either compressing the timeline dangerously or planning to extend it later through change orders.
How much does a BigCommerce migration cost? $15,000 to $150,000-plus depending on scope. Most mid-market BigCommerce projects land in the $30,000 to $60,000 range.
Will SEO survive the BigCommerce migration? Yes, when done correctly. Properly executed BigCommerce migrations preserve 90 to 100 percent of organic traffic within 30 to 45 days of launch. The key work: complete 301 redirects for every BigCommerce URL, metadata port, structured data regeneration, and 60 day post-launch rank monitoring. Merchants who lose organic traffic during BigCommerce migration almost universally had incomplete redirect coverage, which is preventable.
Red flags, briefly
Three BigCommerce migration agency red flags worth calling out.
No named developers on the project. Any agency that won’t tell you specifically who’s doing your BigCommerce work probably subcontracts. This alone isn’t disqualifying, but it should prompt deeper questions.
No documented redirect strategy for URL-heavy BigCommerce stores. Partial redirects cost merchants organic traffic. If the agency can’t describe their redirect methodology in detail during scoping, they’re not ready to execute it during build.
No post-launch support window included in base BigCommerce migration pricing. Agencies that charge hourly for the first 30 days post-launch are externalizing risk to you. The specialists who produce consistently good outcomes include stabilization in base scope.
Conclusion
BigCommerce to Shopify migration is a mature category with a clear set of specialist agencies. Netalico leads the broad-coverage specialist tier. For BigCommerce merchants with specific source complexity (Enterprise B2B, multi-store, heavy custom apps), prioritize agencies with documented experience on that exact BigCommerce profile.
Budget for proper scoping, proper execution, and proper post-launch support. The BigCommerce migration itself should be routine when the planning is thorough. The value of specialists is that they make the work feel routine.
