Epicor Eclipse is engineered for operational precision — high-volume distribution, multi-warehouse management, contract pricing, and job-based orders. Adobe Commerce is built for flexible, modern buyer experiences. On paper, connecting them unlocks the best of both worlds: the operational backbone of a distribution ERP paired with a commerce platform built for today’s B2B buyer.
In practice, most Eclipse + Adobe Commerce integrations struggle — not because of platform limitations, but because of how the connection is designed. Eclipse’s data model doesn’t map cleanly to Adobe Commerce’s native catalog and pricing structure. When integrations skip that reality and apply generic connector logic, the problems start immediately and compound quietly over time.

The good news: these failures are repeatable, recognizable, and fixable. At DotcomWeavers, we’ve worked through these patterns across multiple Eclipse–Adobe Commerce implementations for wholesale distributors. This post breaks down the most common mistakes we see, why they happen, and what the correct approach looks like in production.
Why Eclipse + Adobe Commerce Integrations Are Uniquely Challenging
Most integration guides treat Eclipse like any other ERP — they apply the same connector logic used for NetSuite or SAP and assume it will transfer. It doesn’t.
Eclipse is built around distribution-specific data constructs: matrix pricing that varies by customer, contract tier, and quantity; branch-level inventory tied to specific warehouse locations; job-based and quote-driven order workflows. None of these map one-to-one with Adobe Commerce’s catalog, pricing, or checkout structure out of the box.
The result is that generic ERP integration playbooks applied to Eclipse create predictable failure modes — each with its own downstream impact on pricing accuracy, inventory visibility, order reliability, and the buyer experience. Understanding these failure modes is the first step to avoiding them. It’s also why DotcomWeavers approaches every Eclipse integration by mapping Eclipse’s actual data model first, before a single line of integration code is written.
The 8 Most Common Mistakes (and How to Fix Them)
Mistake 1: Pre-Calculating All Customer-Specific Pricing Into Adobe Commerce
Why it happens: Pre-syncing all pricing seems simpler than setting up real-time lookups. Teams build a sync job, push all contract pricing into Adobe Commerce, and move on.
What it looks like in production: Sync jobs that run for hours. Pricing drift between Eclipse and the storefront — a customer’s contract tier changes in Eclipse, but the storefront serves the old price for days or weeks. Sales reps manually correcting prices at checkout because the platform can’t be trusted.
The fix: Use a hybrid pricing model. Base and list pricing syncs on a schedule — this is low-frequency data that doesn’t require real-time precision. Customer-specific and contract pricing gets resolved via real-time API call to Eclipse at cart or checkout. This keeps sync load manageable while ensuring the price a buyer sees at checkout is the price Eclipse would actually charge.
Mistake 2: Treating Eclipse Branch Inventory Like a Single Stock Number
Why it happens: Default connector setups often flatten multi-location inventory into a single quantity field. It’s the path of least resistance during a fast build.
What it looks like in production: Overselling. “In stock” showing on the storefront for a branch that physically can’t fulfill the order. Inaccurate delivery estimates because the system doesn’t know which warehouse is actually serving the customer.
The fix: Map Eclipse’s branch and warehouse-level inventory data explicitly into Adobe Commerce’s Multi-Source Inventory (MSI) framework. Each branch becomes a source. Fulfillment logic needs to define clearly which branch serves which order — whether that’s nearest-branch routing, a customer-assigned branch, or a priority hierarchy. This requires deliberate configuration, not just a data push.
Mistake 3: Running Full Catalog Syncs Instead of Incremental Updates
Why it happens: Full syncs feel more reliable. Teams assume that syncing everything guarantees nothing gets missed.
What it looks like in production: Sync windows that stretch from minutes to hours. Performance degradation on the storefront during business hours when large syncs are running. Timeouts on catalogs with 50,000+ SKUs — a completely normal catalog size for Eclipse distributors.
The fix: Switch to incremental delta syncs triggered by last-modified timestamps. Only records that have changed since the last successful sync get processed. Reserve real-time sync calls for high-velocity SKUs where pricing or availability changes frequently. Schedule any remaining heavy syncs for off-peak hours. This approach scales — full syncs don’t.
Mistake 4: No Clear System of Record Per Data Domain
Why it happens: Teams assume “the ERP is always right” without making that explicit per data type. Nobody documents what that actually means in practice.
What it looks like in production: A merchandising team updates product descriptions in Adobe Commerce. The next sync overwrites those changes with whatever Eclipse has stored. Or someone updates a product field in Eclipse that’s supposed to live in Adobe Commerce, and the storefront serves stale content. After a few months, nobody can say with confidence which system has the authoritative version of any given piece of data.
The fix: Define and document a system-of-record policy per data domain before integration goes live. A clean split: Eclipse owns pricing, inventory, and orders as financial records. Adobe Commerce owns merchandising content, SEO metadata, and commerce-transaction state. This boundary needs to be documented and enforced in the integration layer itself — not just understood informally by the team who built it.
Mistake 5: Silent Sync Failures With No Monitoring
Why it happens: Integration gets treated as infrastructure — built once, set, and forgotten after go-live. Monitoring is scoped out or deferred.
What it looks like in production: A sync fails at 2 a.m. Nobody notices. A customer calls two days later about wrong pricing. A sales rep flags a stockout that wasn’t actually a stockout. The team spends hours reconstructing what failed and when, with no logs to work from.
The fix: Active monitoring on every sync job — not just a binary pass/fail alert. Establish a baseline for sync latency and error rates during steady-state operation. Set alert thresholds: 2x baseline latency triggers a warning; 5x triggers a critical alert. Monitor error-rate trends over time, not just individual failure events. The goal is surfacing degradation before it reaches customers.
Mistake 6: Point-to-Point Integration Instead of Middleware
Why it happens: A direct Eclipse–Adobe Commerce connection looks cheaper and simpler at the start. With one integration to build, middleware feels like unnecessary overhead.
What it looks like in production: Works fine initially. Then a PIM gets added. Then an OMS. Then a second sales channel. Every new system requires rebuilding a direct connection to Eclipse. The integration layer becomes a web of custom point-to-point connections — each one fragile, none of them observable as a system.
The fix: Use a middleware or integration platform from day one, even for a single Eclipse–Adobe Commerce connection. The upfront cost is higher. The cost of rebuilding a point-to-point architecture to accommodate a second or third system is much higher. Middleware also gives you a single place to monitor, log, and debug data flows across the entire integration layer.
Mistake 7: Ignoring Job-Based and Quote-to-Order Workflows
Why it happens: Most integration templates are built for standard product/cart/checkout flows. Eclipse distributors often don’t sell that way — but the template gets applied anyway and the gaps surface later.
What it looks like in production: Sales reps still working outside the storefront because complex orders can’t be handled online. B2B buyers calling in instead of self-serving because the quote-to-PO workflow doesn’t exist in the commerce platform. The storefront handles simple orders; anything complicated bypasses it entirely.
The fix: Map Eclipse’s job-based and quote-to-order logic explicitly into Adobe Commerce’s B2B quoting and company account structure. This isn’t a post-launch enhancement — it’s a core workflow for most Eclipse distributors. Standard checkout flows can’t be retrofitted to handle this after go-live without significant rework.
Mistake 8: Underestimating Returns and Credit Sync
Why it happens: RMA and credit flows get deprioritized in the initial integration scope. “We’ll handle that in phase two” is one of the most expensive assumptions in any commerce project.
What it looks like in production: Customers see incorrect account balances. Credits issued in Eclipse don’t reflect on the storefront for days. Support ticket volume climbs. The finance team manually reconciles RMAs that should be flowing automatically.
The fix: Build bi-directional sync for returns, credits, and RMA status into the initial integration scope. This isn’t optional functionality for a distributor — it’s a core part of the customer account experience. Scoping it out of phase one means paying to build it later, plus managing the customer service fallout in the meantime.
Every mistake on this list is avoidable — but only if Eclipse’s actual data model is mapped and understood before integration design begins. The right approach starts by treating Eclipse’s distribution-specific constructs as first-class requirements, not edge cases to be handled later. That’s the methodology the team at DotcomWeavers follows on every Eclipse + Adobe Commerce engagement, and it’s what separates integrations that hold up in production from ones that quietly accumulate technical debt from day one.
How to Tell If Your Current Integration Has These Problems
You don’t always need a formal audit to identify a struggling Eclipse–Adobe Commerce integration. These warning signs are common indicators:
- Inventory mismatches between the storefront and Eclipse that require manual correction
- Orders that need human intervention before they reach the fulfillment team
- Pricing discrepancies caught by customers or sales reps before your team notices them
- Sync jobs that have gradually gotten slower without any deliberate configuration changes
- No one on the team can say with confidence which system “owns” a given piece of data
If more than one of these describes your current state, the integration likely has structural problems — not just configuration issues.
What a Well-Built Eclipse + Adobe Commerce Integration Looks Like
The integrations that hold up in production share a consistent set of characteristics:
Real-time or near-real-time inventory by branch, feeding Adobe Commerce’s MSI correctly — so availability reflects what’s actually in the warehouse serving the customer, not a flattened aggregate.
Hybrid pricing resolution — base pricing synced on a schedule, contract and customer-specific pricing resolved via live API call at cart or checkout, so the price is always accurate when it matters.
Documented system-of-record boundaries, enforced at the integration layer — Eclipse owns operational data; Adobe Commerce owns commerce and content data, and neither overwrites the other’s domain.
Active monitoring on every sync job, with baseline tracking and threshold-based alerting, so failures surface before customers notice them.
Job-based and quote workflows mapped into Adobe Commerce’s B2B tools — not bolted on post-launch, but designed in from the start.
Bi-directional returns and credit sync that keeps account balances accurate without manual reconciliation.
A real example: DotcomWeavers helped Wearwell, a wholesale distributor, consolidate their B2B and B2C operations on Adobe Commerce Cloud with Epicor integration, Hyvä for performance, and AI-powered search — achieving the kind of operational visibility and buyer experience that’s only possible when the ERP integration is designed correctly from the ground up.
Getting the Integration Right With DotcomWeavers
The mistakes covered here aren’t Eclipse limitations or Adobe Commerce limitations — they’re integration design decisions that produce predictable, preventable problems. Every one of them is fixable with the right approach, and most of them are far easier to address before go-live than after.
DotcomWeavers specializes in exactly this kind of work: Eclipse–Adobe Commerce integrations built for how distribution businesses actually operate, not how a generic ERP connector assumes they do. Whether you’re starting a new integration, inheriting a struggling one, or evaluating a migration off Epicor Commerce Connect (ECC), we bring the distribution-specific expertise to get the architecture right the first time.
If your Eclipse–Adobe Commerce integration is currently running on ECC and you’re evaluating Adobe Commerce as a replacement platform, the same data-mapping discipline applies. Getting the integration architecture right during a migration is significantly easier than retrofitting it into a live production environment — and it’s something we’ve done before.
