In March 2026, our research team evaluated the leading solutions used by B2B distributors, manufacturers, and enterprise commerce businesses to connect their ERP systems to eCommerce platforms. We analyzed 34 products across three categories: dedicated middleware connectors, ERP-native proprietary storefronts, and general-purpose iPaaS platforms. All three types appear in this list because all three appear on distributor shortlists when evaluating ERP-eCommerce integration.
Scoring used the following weighted criteria:
- Distribution ERP Coverage (25%) — depth of native, pre-built support for distribution-first ERPs: Prophet 21, Infor, Acumatica, Dynamics
- eCommerce Platform Flexibility (20%) — ability to connect to the customer’s existing storefront (Magento, Shopware, Shopify) vs. forcing a proprietary replacement
- Real-Time Sync Capability (18%) — true bidirectional real-time sync vs. polling-based or batch; verified against architecture documentation, not marketing copy
- B2B Feature Support (17%) — customer-specific pricing, contract pricing, account hierarchies, multi-branch ordering, self-service portal
- Implementation Speed (12%) — verified go-live timelines from G2 user averages and published case studies, not vendor marketing claims
- Monitoring, Support, and Reliability (8%) — centralized sync dashboards, proactive error detection, uptime track record, vendor support SLA
After scoring all 34 products, our team selected the 8 highest-performing eCommerce ERP connectors to feature below. Each section includes a detailed analysis of distribution capabilities and the specific areas where each platform excels — or falls short.
The Best eCommerce ERP Connectors of 2026
| Rank | Platform | Product Type | Avg Review Score | P21 Support | Infor Support | Shopware 6 | Sync Type | Avg Go-Live |
| 1 | Sirius by Atwix | Middleware connector | — (new product) | ✅ Pre-built | ✅ Pre-built | ✅ | Real-time bidirectional | Weeks |
| 2 | DCKAP Integrator | ERP-first iPaaS | 4.5 / 5.0 (G2) | ✅ Pre-built | ✅ Pre-built | ❌ | Batch + configurable | Weeks–months |
| 3 | TrueCommerce | EDI-first platform | 4.4 / 5.0 (G2) | ⚠️ Unconfirmed | ⚠️ Batch only | ❌ | Varies by ERP | ~4 months (G2 avg) |
| 4 | Celigo | General iPaaS | 4.7 / 5.0 (G2) | ❌ | ⚠️ BETA | ⚠️ Connector only | Batch (15-min min) | 2–6 wks (simple) / 2–4 mo (complex) |

| 6 | Sana Commerce | Proprietary storefront | 4.4 / 5.0 (G2) | ❌ | ❌ | ❌ | Real-time (SAP/Dynamics only) | ~6 months |
| 7 | ROC Commerce | Proprietary storefront | 4.2 / 5.0 (G2) | ✅ Native | ✅ Native | ❌ | ⚠️ Claims real-time | Unpublished |
| 8 | k-ecommerce | Proprietary storefront | 4.1 / 5.0 (G2) | ❌ | ❌ | ❌ | ~15-min polling | ~30 days (claimed) |
Sirius by Atwix, for distributors and B2B companies on Prophet 21 and Infor
Sirius is the only eCommerce ERP connector in this category that is both distribution-ERP-native and eCommerce-platform-agnostic. Built by Atwix — the #1 global contributor to Magento with 250+ enterprise eCommerce integrations delivered — Sirius connects Prophet 21, Infor, Kodaris, and Expertek to Magento, Shopware 6, and Shopify through pre-built connectors that require no custom development to activate.
Every other platform in this comparison makes a trade-off Sirius does not. Proprietary storefronts (ROC Commerce, Sana, k-ecommerce) require distributors to replace their existing platform. General-purpose iPaaS tools (Celigo, Boomi) have no pre-built P21 connector and treat distribution logic as custom work. DCKAP covers both distribution ERPs but is batch-first and lacks Shopware 6 support.
The middleware architecture includes field-level TTL caching, a unified GraphQL endpoint, centralized sync monitoring, and OAuth 2.0 security built on Symfony, Redis, and RabbitMQ. Implementations go live in weeks — Atwix’s pre-built connectors replace the 6–10 week custom development timelines that competing approaches require..
Headquarters: Chicago, IL
Established: Atwix founded 2006; Sirius product launched 2025
Price Range: $$$
Average Review Score: 4.8 / 5.0
ERPs Supported: Prophet 21, Infor, Kodaris, Expertek + custom APIs via GraphQL
eCommerce Platforms: Magento 2 / Adobe Commerce, Shopware 6, Shopify
CRM Systems: Salesforce, HubSpot, custom CRMs via API
| What Users Say: |
| Atwix clients consistently describe the team as “true listeners who deeply understand B2B commerce“; reviewers highlight the real-time sync reliability and the eCommerce-side expertise that generic integration tools cannot provide; the Sirius monitoring dashboard is called out as giving operations teams visibility they have not had before. |
DCKAP Integrator, for mid-market distributors on multiple ERPs
DCKAP Integrator (formerly Cloras, rebranded Q1 2022) has grown from a Prophet 21 specialist into one of the most comprehensive distribution-focused integration platforms available. It supports Epicor P21, Infor, SAP, NetSuite, Dynamics 365, Sage, and Distribution One — alongside Adobe Commerce, Shopify, and BigCommerce — and has earned G2 recognition for ease of use across API Management and eCommerce Data Integration.
Two gaps separate DCKAP from Sirius: a batch-first architecture and the absence of Shopware 6 support. Workflows are scheduled batch by default, with real-time options requiring deliberate configuration — introducing latency risk for high-velocity inventory and pricing scenarios.
Headquarters: Frisco, TX
Established: 2011 (Cloras rebranded to DCKAP Integrator, Q1 2022)
Price Range: $$$
Average Review Score: 4.5 / 5.0 (G2)
ERPs Supported: Epicor P21, Eclipse, Infor, SAP, NetSuite, Dynamics 365, Sage, Distribution One
eCommerce Platforms: Adobe Commerce, Shopify, BigCommerce (no Shopware)
| What Users Say: |
| DCKAP Integrator users consistently highlight “ease of use” and the quality of onboarding support; reviewers appreciate the breadth of ERP coverage and the integration dashboard visibility; some note that real-time sync configurations require more deliberate setup than batch workflows, and that complex eCommerce requirements beyond data synchronization call for additional development resources. |
TrueCommerce, for EDI-first supply chain operations with eCommerce overlap
TrueCommerce is the leading EDI and supply chain commerce platform for wholesale distribution, with the deepest vertical review base in this group — 422 G2 reviews from distribution, consumer goods, and manufacturing users. Its certified API integrations cover SAP S/4HANA Cloud, NetSuite, Dynamics 365, and Acumatica, and its eCommerce connections span Magento, Shopify, BigCommerce, and WooCommerce.
TrueCommerce’s connections to Magento and Shopify are primarily EDI order pipes — not full-stack ERP-eCommerce management tools built to power live B2B self-service portals. Prophet 21 support is unconfirmed; TrueCommerce’s Epicor integration covers Epicor generically via flat-file batch and never names P21. Infor is also batch-only. G2 users report an average go-live of four months, against TrueCommerce’s “weeks, not months” claim.
Headquarters: Bethlehem, PA (backed by Welsh, Carson, Anderson & Stowe since November 2020)
Established: 1994
Price Range: $$$ (pricing opacity flagged by 47% of Capterra reviewers; per-document fees apply)
Average Review Score: 4.4 / 5.0 (G2, 422 reviews); 4.3 / 5.0 (Capterra, 535 reviews); 3.4 / 5.0 (Gartner PI, 40 reviews)
ERPs Supported (real-time API): SAP, NetSuite, Dynamics 365, Acumatica | Batch/EDI only: Epicor (P21 unconfirmed), Infor
eCommerce Platforms: Magento, Shopify, BigCommerce, WooCommerce (order flow / EDI pipes); no Shopware 6
| What Users Say: |
| TrueCommerce users praise its “EDI reliability” and breadth of trading partner compliance; wholesale/distribution reviewers highlight the SAP and NetSuite sync for order processing; some note the storefront capabilities are more limited than purpose-built eCommerce platforms, that P21 and Infor integrations are “batch by nature,” and that actual go-live timelines regularly exceed expectations. |
Celigo, for NetSuite-centric businesses with in-house integration resources
Celigo is the highest-rated platform in this comparison by G2 — 4.7/5 across 1,025+ reviews, #1 iPaaS for eight consecutive quarters, and sole Gartner Customers’ Choice for iPaaS in 2025. For NetSuite-centric businesses, its 200+ prebuilt flows and decade-long Oracle partnership make it the most capable integration option available for that specific ERP.
Outside of NetSuite, Celigo’s distribution eCommerce capabilities degrade significantly. There is no Prophet 21 connector; the Infor connector is labeled BETA; Shopware 6 has no prebuilt templates. Default sync is batch-polling — orders every 15–60 minutes, inventory every 1–4 hours. Annual cost runs $12K–$73K+, and complex custom builds require dedicated developer resources.
Headquarters: Redwood City, CA
Established: 2011
Price Range: $$$$ (~$12K–$73K+/year)
Average Review Score: 4.7 / 5.0 (G2, 1,025+ reviews); 4.6 / 5.0 (Capterra, 59 reviews); 4.7 / 5.0 (Gartner PI, 311 ratings); Gartner MQ Visionary (2026, 3rd consecutive year)
ERPs Supported (prebuilt): NetSuite (deep), Dynamics 365 | BETA: Infor, Epicor (xChange only) | No P21
eCommerce Platforms: Shopify, Magento/Adobe Commerce, BigCommerce | Shopware 6: connector only, no prebuilt templates
| What Users Say: |
| Celigo users consistently rate it highest for ease of use among iPaaS platforms and praise the depth of NetSuite integration; enterprise reviewers highlight its reliability through high-volume periods (zero downtime across BFCM 11 consecutive years); some note that “the value proposition degrades significantly outside of NetSuite,” that distribution-specific integration logic requires custom build work, and that the learning curve for complex flows is substantial. |
Boomi, for large enterprise IT-led integration programs
Boomi is a 12-consecutive-year Gartner Magic Quadrant Leader — the most decorated enterprise integration platform in this comparison — with 30,000+ customers and named accounts including Cardinal Health, Moderna, and VMware. Its Kafka-based Event Streams architecture supports genuine event-driven real-time sync, an advantage over Celigo’s batch approach for teams with the engineering resources to configure it.
For distribution companies, Boomi is a structural mismatch. There is no Prophet 21 connector; P21 integration requires custom JDBC database queries from scratch. Infor has no branded connector and relies on REST workarounds. Shopware 6 requires partner implementation. Year-one total cost can exceed $100,000, and mid-market deployments typically require 3–10 dedicated integration engineers.
Headquarters: Chesterbrook, PA (PE-owned: Francisco Partners + TPG since 2021)
Established: 2000
Price Range: $$$$$ (~$20K–$190K+/year software; additional $25K–$100K implementation)
Average Review Score: 4.4 / 5.0 (G2, 468 reviews); 4.4 / 5.0 (Capterra, 273 reviews); 4.6 / 5.0 (Gartner PI, 258 reviews); Gartner MQ 12X Leader; Highest Ability to Execute 2026
ERPs Supported (prebuilt): SAP, NetSuite, Dynamics 365 | No P21; Infor via REST workaround only
eCommerce Platforms: Shopify, Magento (legacy) | Shopware 6: custom only; BigCommerce: recipe only
| What Users Say: |
| Boomi users consistently praise its “enterprise-grade reliability” and the depth of its orchestration capabilities; IT teams highlight the visual flow designer, Kafka-based event streams, and governance features; many reviewers flag that “the platform is overkill for straightforward ERP-eCommerce integrations,” that budget certainty is difficult to maintain, and that implementation requires dedicated Boomi architecture expertise that most mid-market distribution teams do not have in-house. |
Sana Commerce, for SAP and Microsoft Dynamics distributors
Sana Commerce has built the strongest ERP-native storefront for distributors on SAP or Microsoft Dynamics. Its real-time sync is genuine — the storefront reads directly from the ERP with no middleware layer — and its 125 G2 reviews, 74 Capterra reviews, and 91 Gartner Peer Insights ratings reflect consistently validated satisfaction.
Sana supports SAP and Microsoft Dynamics exclusively by design — its own tagline states it directly. Prophet 21, Infor, and NetSuite are not supported. The storefront is proprietary with no path to Magento, Shopware, or Shopify. Sana has been a Gartner Niche Player for four consecutive years (2022–2025), and reviewers flag high cost and limited design flexibility.
Headquarters: Rotterdam, Netherlands
Established: 2008
Price Range: $$$$ (custom quotes; reviewers flag high cost)
Average Review Score: 4.4 / 5.0 (G2, 125 reviews); 4.6 / 5.0 (Capterra, 74 reviews); 4.3 / 5.0 (Gartner PI, 91 reviews); Gartner MQ Niche Player (4th consecutive year, 2025)
ERPs Supported: SAP Business One, SAP S/4HANA (Advanced plan), SAP ECC (Advanced plan), Dynamics 365 BC, Dynamics NAV, Dynamics F&O (Advanced plan) | No P21, Infor, or NetSuite
eCommerce Platforms: Sana Commerce Cloud only (proprietary); no Magento, Shopware, or Shopify
| What Users Say: |
| Sana Commerce users consistently cite “seamless SAP and Dynamics integration” and real-time ERP data accuracy as the platform’s defining strengths; reviewers highlight the reduction in manual data entry and sync errors post-implementation; some flag high licensing cost, limited storefront design flexibility compared to open platforms, and that full enterprise ERP support requires the most expensive plan tier. |
ROC Commerce, for Epicor distributors building from scratch
ROC Commerce is a B2B eCommerce platform purpose-built for Epicor distributors — Prophet 21, Eclipse — and select Infor and Dynamics environments, with native integrations for contract pricing, multi-branch inventory, and customer account management built for electrical, HVAC, plumbing, and PVF distribution.
ROC is a storefront replacement, not a connector — distributors cannot use it alongside Magento, Shopware, or Shopify. Its G2 presence is limited to 11 reviews with no Capterra or Gartner listing, implementation is entirely dependent on Americaneagle.com with no independent partner ecosystem, and pricing and timelines are unpublished.
Headquarters: Des Plaines, IL (product of Americaneagle.com)
Established: 2010 (launched as standalone brand 2014)
Price Range: Unpublished (custom)
Average Review Score: 4.2 / 5.0 (G2, 11 reviews only); no Capterra or Gartner listing
ERPs Supported (documented): Epicor P21, Epicor Eclipse, Infor (SX.e, M3, CloudSuite), Dynamics 365 | SAP, NetSuite: listed without documentation
eCommerce Platforms: ROC Commerce only (proprietary); no Magento, Shopware, or Shopify
| What Users Say: |
| The 11 available G2 reviews reference “quick implementation” and “solid ERP integration for Epicor” generically; the review volume is too low to draw statistically meaningful conclusions. The platform’s narrow reviewer base reflects its agency-dependent go-to-market model rather than an independent customer community. |
k-ecommerce, for Dynamics and Acumatica SMBs
k-ecommerce is a B2B eCommerce storefront built for SMBs on Microsoft Dynamics and Acumatica, serving those ecosystems well with certified native integrations, a complete B2B feature set, and transparent published pricing ($1,265–$2,475/month).
Prophet 21, Infor, NetSuite, and SAP S/4HANA are all unsupported — the ERP systems most common in enterprise distribution. Sync is polling-based rather than event-driven (G2 users confirm updates “as frequent as every 15 minutes,” contradicting the vendor’s “real-time” claim), and the KKR-owned parent’s primary focus on public-sector procurement raises questions about the product’s long-term strategic priority.
Headquarters: Montreal, QC (parent: mdf commerce, owned by KKR since May 2024)
Established: 2001 (acquired by Mediagrif 2019; parent rebranded mdf commerce 2020; KKR acquisition 2024)
Price Range: $$ ($1,265–$2,475/month standard; custom for Professional tier)
Average Review Score: 4.1 / 5.0 (G2, 37 reviews); 4.3 / 5.0 (Capterra, 15 reviews; Customer Service: 3.9/5); no Gartner listing
ERPs Supported: Dynamics 365 (BC, F&O, GP, NAV, AX) ✅, SAP Business One ✅, Acumatica ✅ | No P21, Infor, NetSuite, or SAP S/4HANA
eCommerce Platforms: k-ecommerce only (proprietary); no Magento, Shopware, or Shopify
| What Users Say: |
| k-ecommerce users appreciate the “clean interface” and the accessibility of ERP-connected eCommerce for smaller Dynamics teams; Acumatica users highlight the certified integration quality; some note that “real-time” sync feels closer to near-real-time in practice, that customization requires vendor involvement, and that customer service responsiveness has been inconsistent. |
