Best BigCommerce to Shopify Migration Services in 2026-2027

Disclosure: eSEOspace publishes this blog and ranks itself first. Every other entry was researched independently and links to its own site.

How we evaluated these agencies

Every entry below was assessed against the same five questions, using what each firm publishes on its own site plus ratings it cites publicly.

1. Does the firm treat this as a migration or as a replatform? A migration moves records. A replatform rethinks merchandising, theme, checkout and integrations while the records move. Both are legitimate. Buying one while expecting the other is where projects go sideways.

2. Is the SEO continuity plan explicit? We looked for named handling of 301 redirect mapping, URL structure preservation and SEO metadata transfer on the service page itself, not as an upsell mentioned later.

3. How much commercial and process detail is public? Firms that publish scope tiers, cost bands, timelines or a named methodology let you qualify them before a sales call. That is a real advantage for a buyer running a shortlist.

4. Does the published work resemble your store? Named client work in your vertical, at your catalog size, is stronger evidence than an aggregate project count. Where a firm cites aggregate figures instead, we say so and attribute them.

5. Platform credentials on both sides. Shopify Partner and Shopify Plus tiers are the common signal. Credentials on the BigCommerce side are rarer and specifically useful here.

One note on the credentials in this article: partner tiers, review scores and project counts below are as stated by each firm on its own site or on its public review profile. We have attributed them in place rather than presenting them as independently audited.

Comparison table

1. eSEOspace

Founded 2019.

We rank ourselves first because the failure mode we see most often in this migration is not a broken data import, it is a merchant who moved cleanly and then lost a third of non-brand organic traffic in the following quarter. BigCommerce and Shopify structure URLs, faceted pages and product taxonomies differently. If nobody owns the redirect map at URL level, and nobody is watching Search Console the week after cutover, the platform change gets blamed for a problem the migration plan created.

Our approach treats the replatform and the search program as one project. That means the redirect map is built from a full crawl of the live BigCommerce store rather than from a sitemap export, metadata and structured data move with the products, and internal linking is rebuilt for the new collection structure instead of being inherited. Post-launch, the work continues as ecommerce SEO and conversion rate optimization for ecommerce, with insights and analytics instrumented before cutover so you have a clean before-and-after baseline. Where the move is also a redesign, that runs through our ecommerce design and development practice.

Best for: merchants whose organic and paid channels carry most of the revenue, and who want one accountable team for the build, the redirects and the recovery curve afterwards.

Worst fit: if you want a pure data lift with no strategy layer, we are the wrong shape and more expensive than you need. A tooling-led shop will move the records faster and cheaper. Talk to us only if the search outcome is part of the brief.

2. WebVello

Founded 2024.

WebVello is a WordPress, Shopify and SEO firm, which makes it a sensible fit for the large middle of this market: stores that need a competent Shopify build and someone who understands search, without the process overhead of an enterprise replatform. The combination matters here because plenty of BigCommerce merchants also run a separate WordPress content site, and the migration is the moment those two properties either get connected properly or drift further apart.

Best for: small and mid-size merchants who want the store build, the content site and the search work handled by one team, and who value responsiveness over formal process documentation.

Worst fit: enterprise buyers running a procurement process. As a newer firm, WebVello is competing on delivery rather than on a decade-long client wall, so if your board wants a long list of comparable enterprise replatforms in the room, look at Netalico, Makro or 1Digital instead.

3. Netalico Commerce

Founded 2013. North American in-house team, with offices listed in San Francisco, Los Angeles, New York, Miami, Toronto and São Paulo.

Netalico publishes the most useful migration page in this category. It sets out scope tiers by merchant size (simple sub-$1M store, $1M to $10M mid-market, $10M+ Shopify Plus enterprise), a stated range of $15,000 to $150,000+, and an 8 to 24 week timeline. It leads on data preservation, 301 redirect SEO continuity and zero-downtime cutover. For a buyer building a shortlist, that page does half your qualification work before you ever get on a call.

The firm describes itself as a Shopify Plus Premier Partner and cites a 5.0 Clutch rating on its own site. Published client work includes Big Green Egg, Oatly, Feetures, Mijenta Tequila, Alpenglow Sports, Petite 'n Pretty, The Country Butcher and Shop QEP, which is a credible mid-market and enterprise spread.

Best for: $1M+ merchants who want a Shopify Plus grade migration and care most about keeping organic rankings and order history intact through cutover.

Worst fit: small stores that want a cheap catalog transfer. The smallest published tier still frames migration as a multi-week engagement, so a sub-$500k store that just needs products moved will overpay. Optimum7 is the better economics there.

4. Makro Agency

Founded 2018. Montréal, Canada and Miami, Florida. States a team of 52, senior and in-house.

Makro frames the whole category correctly: the platform is not the risk, the execution is. Its published six-gate methodology (Audit, Data Map, Build, Parallel Run, Cutover, Rollback) makes a migration observable and reversible instead of one all-or-nothing launch night. The parallel run is the part worth paying for. Running the new store alongside the old one surfaces the data mapping errors that otherwise show up as customer service tickets in week two. The firm states Shopify Premier partner tier on its site, and publishes a long-form BigCommerce migration guide alongside the service page.

Published client work includes Bio-K+, Wire America / DWC, Ennis Fabrics, NewPro Containers, JC Perreault, TA Appliances, Clarius and 7-Eleven Canada, and the site cites a 60,000+ SKU industrial catalog migration plus DTC-plus-B2B moves.

Best for: risk-averse merchants and large or B2B catalogs where a bad cutover is genuinely unacceptable. Buy this for the rollback gate.

Worst fit: merchants optimising for the lowest price. A six-gate process with parallel running is more ceremony than a few-hundred-SKU store needs, and the North America based team prices accordingly.

5. 1Digital Agency

Founded 2012 as stated on its about page, though the same site separately cites "15 Years in eCommerce". Philadelphia, Pennsylvania, described as remote-first with a US core team. States 50+ team members.

1Digital is the rare shop credentialed on both sides of this exact move: it states BigCommerce Elite Partner and Shopify Plus Partner status, along with Google Partner status, and cites 4.9/5 from 941+ verified reviews. That dual credential is the whole argument for hiring them. Most BigCommerce to Shopify pain lives on the source side, in custom fields, category logic and price lists, and 1Digital has actually built on the platform you are leaving. Its migration page speaks that vocabulary, covering the mapping of BigCommerce custom fields into Shopify metafields and preserving SEO equity, and it publishes commercials: from $185/hour, with fixed-fee proposals typically $25K to $150K+. The site also claims 200+ migrations with zero failed cutovers, which is a self-reported figure worth asking them to walk through.

Published client work includes Steinway & Sons, Kate Spade NY, Hitachi, Synchrony, Dansk, Hussey Seating Co., Di Bruno Bros, Rollie, Sagebrook Home and JB Tools.

Best for: heavily customised or long-lived BigCommerce stores, and merchants who want one agency covering SEO and PPC so both channels are protected through the replatform.

Worst fit: brands wanting a boutique, design-led rebuild delivered by a small senior pod. This is a broad full-service shop spanning SEO, PPC, design and development across 400+ brands. For high-craft creative, Charle is the better call.

6. Charle Agency

Founded 2018. Offices listed in New York, London and Manchester.

Charle runs a dedicated BigCommerce to Shopify service line aimed at growing consumer brands, and it owns the whole move: secure transfer of products, customers and orders, custom theme design, 301 redirect mapping with URL structure preservation, and post-launch support. It describes itself as a Shopify Plus accredited agency and a recognised Shopify Partner with Plus experience. What distinguishes it is that the design rebuild is the point rather than an add-on, so you come out of the migration with a store that looks different, not a like-for-like theme port.

The published case studies skew food, beverage, beauty and lifestyle: Muc-Off, 111Skin, Cambridge Satchel, Rude Health, Doisy & Dam, Bart Ingredients, CleanCo, Des Kelly, Joel & Son, Cooks & Co and Vytronix.

Best for: DTC and CPG brands, particularly UK and EU facing ones, that want the replatform bundled with a real design rebuild.

Worst fit: complex B2B catalogs, wholesale price lists or heavily ERP-integrated BigCommerce stores. The published work is consumer-brand heavy, and pricing is quote-only after a tailored consultation, so if you need cost bands before the first call, Netalico and 1Digital give you more to plan against.

7. Blackbelt Commerce

New York City base, with stated presence across 5+ global regions.

Blackbelt is Shopify-only, and its BigCommerce to Shopify page argues the move on capability rather than cost: BigCommerce constrains customisation, while Shopify's app ecosystem, theme flexibility and checkout extensibility hand control back to the merchant. That is an honest framing, and it is the right reason to migrate if it is your reason. Depth is the pitch. The site claims 1,000+ Shopify merchants served and 1.5K+ stores launched, and states Official Shopify Partner, Certified Shopify Plus Expert and "Premier Shopify Agency" status with a 5.0/5 Shopify partner rating. Note that its own site dating is inconsistent, pairing "Serving Stores Since 2015" with a "12 Years Experience" stat, so confirm tenure directly if that matters to your evaluation.

The published client wall spans apparel, outdoor, supplements and uniforms, including Judith Leiber, Silver Lining Herbs, Erica Wilson, Minaal, Gym and Fitness, Metro School Uniforms, Lindísima and Gogglesoc.

Best for: merchants who specifically want checkout extensibility, app ecosystem depth or heavy theme customisation after the move, and who weigh a long Shopify-only track record and a visible client roster above formal process documentation.

Worst fit: buyers who want cost bands, a stated timeline and a documented rollback plan in hand before committing. If that is your procurement standard, Makro and Netalico are built for it.

8. DigitalSuits

DigitalSuits positions as a full-cycle ecommerce agency and AI development company, and runs the migration through a structured six-phase workflow that includes QA testing and post-migration support. It leans harder than peers on data-handling rigor: the migration page specifies HTTPS with 128-bit SSL encryption and GDPR compliance for the transfer itself, which is a meaningful distinction when you are moving a customer database out of one vendor's infrastructure and into another's. The site publishes outcome metrics from prior replatforms, including a 27% increase in organic conversion rate and a 62% reduction in page load times, and cites a 5.0 Clutch rating from 55+ reviews across 200+ delivered projects. It states Certified Shopify Partner and Certified Shopify Plus Partner status.

Published client work includes Scentbird, KOIO, DUXIANA, Laird Superfood, TRUE Linkswear, Rollie Nation, 4ocean, Lull, Grace & Lace, BPI Sports and Poketo.

Best for: merchants with GDPR or data-privacy obligations around customer records, and brands that want the migration paired with performance and automation work rather than treated as a one-off transfer.

Worst fit: buyers who need to sit down with an on-shore delivery team before signing. Team structure and location are things you will establish on the consultation call rather than from the site, so build that into your first conversation.

9. Optimum7

Coral Gables, Florida.

Optimum7 is the tooling-led option, and it is here on merit for a specific job. Its migration is largely automated on in-house scripts, with stated support for 70+ source platforms, 2,000+ migrations completed and a 100% uptime guarantee for the source store during the move. Its BigCommerce to Shopify page quotes a typical 2 to 3 week timeline, an order of magnitude faster than the agency-led alternatives in this ranking, and covers products, categories, customers, order history, reviews, SEO metadata and 301 redirects. The firm states Shopify Partner status and certified Shopify developers, and runs a technology and agency partner program. Its broader specialty is functionality-gap work, which is useful when the migration exposes a BigCommerce feature Shopify does not replicate natively.

Best for: merchants whose priority is a fast, clean data transfer at volume: large catalogs, deep order history, or anyone who has already picked a Shopify theme and just needs the records moved without downtime.

Worst fit: brands wanting a design-led replatform or a named senior pod on the account. Automation-first is the wrong shape when the actual job is rethinking merchandising and UX. Reference checks should be requested directly, since the public case for the firm is built on aggregate counts rather than named brands.

Who should hire which

Frequently asked questions

How long does a BigCommerce to Shopify migration actually take?

It depends entirely on which product you bought. Optimum7 states a typical 2 to 3 weeks for its automation-led transfer. Netalico states 8 to 24 weeks for its tiered mid-market and Plus replatforms. Neither is wrong. The first moves your records onto a theme you have already selected. The second rebuilds the storefront, remaps the data model and runs a controlled cutover. Decide which one you are actually buying before you compare timelines, because a 3 week quote and a 20 week quote answering the same brief means one of them misunderstood the brief.

Will I lose search rankings when I migrate?

You will lose some short-term visibility on almost any replatform, and the size and duration of that dip is largely a function of how well the redirect map is built. BigCommerce and Shopify handle URL structures, collection paths and product handles differently, so a meaningful share of your URLs will change. The mitigation is a URL-level 301 map derived from a full crawl of the live store, metadata and structured data carried across with the products, and Search Console monitored daily for the first few weeks. Netalico, Charle, 1Digital and Optimum7 all name SEO continuity or 301 redirect handling on their migration pages. Make sure whoever you hire will show you the redirect map as a deliverable, and pair the launch with an organic SEO program that starts before cutover, not after the dip.

What should a BigCommerce to Shopify migration cost?

Two firms in this ranking put numbers on a public page. Netalico states $15,000 to $150,000+ across its scope tiers. 1Digital states from $185/hour with fixed-fee proposals typically $25K to $150K+. Treat those as the mid-market and enterprise reference points. A straightforward data transfer for a smaller catalog sits well below the bottom of those ranges, and a full Plus replatform with custom checkout work, ERP integration and a design rebuild sits at or above the top. Everyone else here quotes after a consultation, which is normal for scoped work.

What is the hardest data to move?

Anything BigCommerce stores that Shopify does not have a native equivalent for. Custom fields have to be mapped into Shopify metafields. Customer group pricing and wholesale price lists need a plan, usually involving Shopify B2B or an app. Complex category logic rarely maps one-to-one onto collections. Order history and reviews are usually fine but need explicit inclusion in scope, because "migrate the store" is not the same instruction as "migrate the store with 6 years of orders and 40,000 reviews attached to the right products." This is exactly why 1Digital's BigCommerce-side credential is worth something on a complicated store, and why any agency you hire should run a database and data-model review before quoting a fixed fee.

Should I redesign at the same time as I migrate?

If the current storefront converts well, migrate first and redesign afterwards, so that if traffic or revenue moves you know which change caused it. If the storefront is the reason you are leaving BigCommerce, do both at once and accept that attribution will be murkier. Charle builds the design rebuild into the migration by default, and it is the right call for consumer brands where the old store is visibly dated. Either way, set up conversion tracking and baseline reporting before cutover, and plan the post-launch conversion rate optimization work as a separate phase with its own measurement window.

How do I verify an agency's partner tier and reviews?

The credentials cited in this article are as stated by each firm on its own site or public review profile, and you should confirm them yourself before signing. Look the agency up in the Shopify partner directory to check the tier it claims, open the Clutch or review profile behind any rating and read the negative reviews specifically, and ask for two references from migrations of comparable catalog size in the last 18 months. If a firm cites aggregate figures like project counts or a zero-failure record, ask them to walk you through one of those projects in detail. Good agencies enjoy that conversation.

Conclusion

There is no single best BigCommerce to Shopify migration agency, because the label covers at least three different products. Optimum7 sells speed and volume. Netalico, Makro, Charle and 1Digital sell a controlled replatform with process, design or source-platform fluency attached. Blackbelt and DigitalSuits sell Shopify build depth and data-handling rigor respectively. WebVello sells build plus search for stores that do not need enterprise ceremony. We rank ourselves first because the outcome we optimise for, keeping the organic and paid revenue you already have while the platform changes underneath it, is the one most likely to be underpriced in the other quotes you receive.

Whichever way you go, insist on three things in writing: a URL-level redirect map as a named deliverable, a documented plan for what happens if cutover fails, and a baseline analytics report captured before launch so the before-and-after is not a matter of opinion. Get those and the platform change becomes a project. Skip them and it becomes a gamble. If you want a second opinion on a migration quote you have already received, get in touch.
