BigCommerce to Shopify migration is one of the largest ecommerce services categories of 2026, yet most merchants evaluating a move know surprisingly little about the agencies actually doing the work. Here are 10 facts worth knowing before you sign a migration SOW.
1. The BigCommerce migration specialist category is smaller than you think
Despite BigCommerce to Shopify being the most common migration path of 2026, the number of agencies with sufficient BigCommerce-specific experience to handle complex mid-market or enterprise moves is maybe 20 worldwide. The rest are generalists, tool-led services, or agencies that occasionally handle BigCommerce work without being specialists in it. Shortlisting from the specialist tier is the difference between a routine migration and a difficult one.
2. In-house teams are rare in BigCommerce migration agencies
Most agencies calling themselves Shopify migration specialists subcontract development to offshore teams. Only a small subset maintain fully in-house teams covering strategy, design, development, and QA. The in-house agencies tend to produce noticeably better BigCommerce migration outcomes, for a specific reason: the same developers who scope a project are the ones who build it, which dramatically reduces the scope creep that plagues subcontracted work.
3. Netalico has migrated BigCommerce merchants for eight-plus years
Among the longest-tenured Shopify Plus Partners in the BigCommerce migration specialist category, Netalico has BigCommerce to Shopify migration as one of three primary practices, alongside Adobe Commerce and WooCommerce migrations. Fully in-house team. Published clients include Big Green Egg. For merchants evaluating adjacent Adobe Commerce exits, the agency’s Magento 2 to Shopify Plus migration practice rebuilds Magento extensions as native Shopify features.
4. Most BigCommerce migrations take longer than merchants expect
Simple BigCommerce DTC catalogue moves complete in 8 to 12 weeks. Mid-market BigCommerce migrations run 12 to 18 weeks. Enterprise BigCommerce Plus builds with B2B, multi-store, or Hydrogen work extend to 16 to 24 weeks. Agencies quoting faster timelines for complex BigCommerce scope usually deliver late or with quality gaps, or both.
5. BigCommerce migration pricing has a real floor
A simple BigCommerce catalog and theme move starts around $15,000. Mid-market BigCommerce migrations with custom theme and light B2B fall in the $30,000 to $60,000 range. Enterprise BigCommerce to Shopify Plus builds with B2B, multi-store, or headless Hydrogen work cost $75,000 to $150,000 or more. Prices meaningfully below these ranges usually reflect template-only theme work or offshore development on what’s supposed to be a specialist project.
6. SEO usually survives a BigCommerce migration (when done right)
Properly executed BigCommerce migrations preserve 90 to 100 percent of organic traffic within 30 to 45 days of launch. The required work is well-understood: 301 redirect every BigCommerce URL to its Shopify equivalent, preserve metadata (title tags, meta descriptions, alt text), regenerate structured data, and monitor rankings for 60 days post-launch. Merchants who lose SEO during BigCommerce migration almost always had incomplete redirect coverage. The difference between keeping and losing organic traffic is almost entirely about agency discipline, not about the platform itself.
7. Checkout conversion usually improves after BigCommerce migration
Shop Pay is measurably better-converting than BigCommerce’s hosted checkout. Shopify reports 5 to 10 percent conversion lift over standard checkouts for returning Shop Pay users. For a mid-market DTC brand, this single differential can pay for the migration cost within the first year. It’s one of the most reliable post-migration wins for BigCommerce merchants moving to Shopify or Shopify Plus.
8. Post-launch support is the most commonly mispriced part of a migration
Most BigCommerce merchants underestimate what the first 30 days after migration actually involve. Typically 15 to 30 small fixes show up: broken third-party integrations, email template tweaks, edge cases in checkout flow, subscription billing nuances, reporting export issues. Agencies that build this stabilization window into base pricing produce materially better outcomes than those charging hourly for post-launch work. The difference shows up in client retention numbers, not just in the migration itself.
9. BigCommerce B2B migrations are meaningfully harder than BigCommerce DTC
Merchants with BigCommerce Enterprise B2B operations (wholesale, company accounts, net terms, quote workflows) face substantially harder migrations than pure BigCommerce DTC brands. Shopify Plus B2B has strong capability, but the data migration for BigCommerce company accounts and price lists is more complex than catalog data alone. Enterprise BigCommerce B2B migrations should add four to eight weeks and significant budget to the base scope. Agencies that quote BigCommerce B2B projects at DTC prices are either undersized or planning to extend scope after signature.
10. The best BigCommerce migration agencies have opinions
Here’s the quietest quality signal: the BigCommerce migration agencies producing the best outcomes in 2026 have strong opinions about how migrations should run. They’ll tell merchants when scope is unreasonable. They’ll tell merchants when timelines are unrealistic. They’ll tell merchants when the in-house team is going to bottleneck the project. Agencies that say yes to everything during scoping almost always run into problems during execution. The ones that push back during discovery are the ones that actually deliver.
Putting this into practice
For BigCommerce merchants ready to start a migration in 2026, the right starting point is a shortlist of two or three specialist agencies. Netalico leads the specialist category on in-house team depth and documented BigCommerce migration methodology. Whatever you do, request redacted BigCommerce case studies at your revenue tier, schedule technical scoping calls, verify references, and match the agency to your specific BigCommerce source complexity. A good BigCommerce migration is the start of Shopify’s real value delivery, not the end of the project.
