SuiteCommerce to Shopify Migration: How to Preserve NetSuite Order History and B2B Portal Features

As more NetSuite merchants look to modernize their eCommerce stack, Shopify has become an increasingly popular choice—especially among those looking for improved design flexibility, frontend speed, and a broad ecosystem of third-party apps.

However, this migration comes with a hidden cost for merchants previously using SuiteCommerce: the loss of historical customer data and B2B functionality that NetSuite customers rely on.

At UnlockCommerce, we’ve seen this scenario play out repeatedly: a merchant using SuiteCommerce decides to move to Shopify for a fresh start—only to realize their B2B customers can no longer see past orders, repeat purchases, or view invoices.

The implications of this gap go beyond inconvenience. It disrupts buyer workflows, creates friction in the customer experience, and introduces new costs in the form of support load and lost revenue.

This post explores the core challenges of this migration, the cost of inaction, and a practical solution that combines Shopify with SuiteCommerce MyAccount (SCMA) to deliver a best-of-both-worlds experience.

The Core Problem: Data Lock-In and the Limits of Shopify for B2B

NetSuite and SuiteCommerce provide a tightly integrated experience for B2B buyers. Customers logging in through SuiteCommerce can access everything: their full order history, quotes, invoices, payment records, support cases, and more. This historical view isn’t just a convenience—it’s an essential part of how B2B buyers operate. They often reorder the same products, monitor open balances, and rely on a portal for self-service.

When migrating to Shopify, this continuity is broken. While the storefront might look cleaner and the checkout smoother, the backend doesn’t carry over easily:

Historical orders often can’t be imported due to mismatched product catalogs, outdated SKUs, or expired promotions.
Even when orders are migrated, they don’t retain the full context—such as invoice status, quote references, or NetSuite-native links.
Shopify’s native B2B tools (as of today) don’t support key use cases like viewing invoices, paying balances, submitting support cases, or reviewing detailed account history.

The result: B2B customers log in and find an empty account dashboard. No orders. No reorder options. No way to track invoices. And worse—no reason to trust the new platform.

Adjacent Problems: Support Load and Operational Friction

This missing functionality causes more than just user frustration. It creates operational and support challenges for merchants:

Support overload: Customers begin calling or emailing to request past orders, invoices, or tracking information they once accessed themselves. Support teams scramble to respond with manual lookups.
Sales disruption: Account managers field reorder requests manually, losing time and risking error in the process.
Inconsistent data: With Shopify and NetSuite now operating independently, customer profile updates (emails, shipping addresses, payment terms) may be out of sync.
Reduced loyalty: B2B buyers expect efficiency. When the buying process becomes slower and more dependent on human intervention, buyers may explore competing vendors with better digital portals.

These hidden costs accumulate fast. Merchants may underestimate the long-term impact until customer complaints mount and efficiency breaks down.

Ignoring the Gap: Lost Revenue and Customer Churn

Let’s explore what’s really at stake when merchants don’t address this disconnect:

1. Lost reorders: For many B2B merchants, reorders make up 60–80% of sales. If buyers can’t find previous purchases or easily replicate them, many will delay or abandon the order. Every friction point in the buying journey reduces conversion.

2. Customer churn: Buyers who once had full self-service visibility are now dependent on emails or calls. This shift increases their effort and decreases satisfaction—especially when competitors offer smoother experiences. In B2B, relationships matter, but so does convenience.

3. Rising operational costs: Without automation, staff handle more manual tasks. Customer service teams now field routine requests like “send me my last invoice” or “what did I order last quarter?” These time-consuming interactions could have been avoided with a proper self-service portal.

4. Stalled Shopify ROI: The benefits of switching to Shopify—modern UX, marketing flexibility, app ecosystem—are diminished when core B2B functionality is lost. Merchants may end up investing additional time and money building custom portals or integrations that replicate what they already had in SuiteCommerce.

The good news? There’s a better way.

The Solution: Seamless SSO from Shopify into SCMA

Rather than attempting the near-impossible task of perfectly migrating order history and duplicating NetSuite functionality in Shopify, we’ve taken a different approach.

Our solution: Leverage SuiteCommerce MyAccount (SCMA) as a customer portal, connected via Single Sign-On (SSO) from Shopify.

Here’s how it works:

Customers log in through Shopify as usual.
When they click to view their account, orders, invoices, or quotes, they are redirected—branded and seamlessly—into SCMA.
Within SCMA, they see their full transaction history, can make payments, download invoices, update their profile, and more.
All data is live from NetSuite. No need to sync. No delay. No custom connector required.

The frontend remains Shopify. The account backend is SCMA. This architecture plays to the strengths of both platforms.

Why This Hybrid Model Makes Sense

From a technology and business standpoint, this hybrid approach offers significant advantages:

No data duplication: Instead of struggling to migrate historical records to Shopify, just maintain them in NetSuite where they belong.
Always in sync: Since SCMA connects directly to NetSuite, there’s no delay or mismatch in data. The customer always sees the latest orders, invoices, and quotes.
Reduced complexity: No need for a custom-built portal or costly integrations. SCMA already handles the B2B use cases out of the box.
Preserved functionality: Even as Shopify improves its B2B features, SCMA still leads in areas like invoice payment, quote approval workflows, and support case management.
Customer satisfaction: Buyers retain the ability to reorder, manage their account, and self-serve—all from the system they were already using.

This isn’t about promoting SCMA as a full storefront replacement—Shopify can absolutely serve as the public-facing eCommerce layer. But for NetSuite merchants, SCMA remains a valuable piece of the B2B experience, and it can be used strategically as a complement to Shopify.

A Win-Win for Merchants and the NetSuite Ecosystem

This solution not only solves pain points for merchants and their customers—it also helps reinforce the value of the NetSuite platform in a modern, composable commerce environment.

Merchants benefit from a better B2B experience, lower support burden, and increased customer retention.

At the same time, NetSuite retains relevance in the eCommerce stack by keeping customers engaged through SCMA—even as they move away from SuiteCommerce as a full storefront.
