Connecting your B2B storefront to your ERP is the part of going online that quietly decides everything: whether buyers see real stock and their real price, and whether your team stops rekeying orders. The software that does it falls into three camps, and they are not interchangeable.
This guide compares the best B2B e-commerce ERP integration software for 2026 across all three: dedicated e-commerce connectors, general-purpose iPaaS like Celigo and Boomi, and native-integration platforms that skip separate middleware entirely. It covers how each works, what to look for, what it costs, and how to choose.

The best B2B e-commerce ERP integration software in 2026
The best B2B e-commerce ERP integration software in 2026 spans three groups: connectors like Celigo, APPSeCONNECT, and DCKAP Integrator; general iPaaS like Boomi, MuleSoft, Workato, and Jitterbit; and native-integration platforms like Sana Commerce, WizCommerce, k-eCommerce, and commercebuild. The list below is grouped by approach, because the right pick depends on whether you are connecting an existing store or choosing a new platform.
Dedicated e-commerce-ERP connectors
1. Celigo
Celigo is the best fit for NetSuite-centric teams that want prebuilt, production-ready integration flows, and it is the iPaaS most often paired with NetSuite e-commerce. Its strength is a deep NetSuite ecosystem with templates for common flows, data mapping, and real-time monitoring. The trade is that it is a separate platform you license and maintain, with cost that scales by flow and usage, so it suits teams ready to own an integration layer.
2. APPSeCONNECT
APPSeCONNECT is the best fit for mid-market distributors and manufacturers running SAP, Dynamics, NetSuite, Sage, or Acumatica that want ERP-aware connectors with a low-code builder. It offers prebuilt connectors across those ERPs, a visual ProcessFlow designer business users can adjust, and real-time plus batch sync with monitoring and retries, aiming for ERP-specific integration without enterprise-tier weight.
3. DCKAP Integrator
DCKAP Integrator is the best fit for distributors that want a connector built around distribution ERPs like Epicor Prophet 21, NetSuite, and Dynamics, managed from one dashboard. It is purpose-built for distribution and centralizes integrations and data in a single view. It leans toward scheduled syncing, so confirm the cadence matches how fast your stock moves.
General-purpose iPaaS
4. Boomi
Boomi is the best fit for enterprises connecting many systems, with a large low-code connector library and a long track record. It is powerful and broadly capable, with EDI and API management as add-ons. For mid-market distributors the trade is cost and implementation complexity, and some distribution ERPs like Prophet 21 need custom work rather than a prebuilt connector.
5. MuleSoft
MuleSoft is the best fit for large enterprises that want an API-led platform to connect almost any system, cloud or on-premise. Its Anypoint Platform is among the most capable and also among the most developer-heavy and expensive. It suits organizations with integration architects and a broad API strategy, not a single e-commerce-to-ERP flow.
6. Workato
Workato is the best fit for teams that want no-code, recipe-based automation across an ERP and surrounding apps, owned by business and IT together. It excels at internal workflow automation with a large connector library and AI-assisted building. The trade is that pricing can escalate as you add processes, and it is lighter on out-of-the-box EDI and B2B-specific features.
7. Jitterbit
Jitterbit is the best fit for mid-market teams that want standard ERP-to-SaaS integration with cost and speed as the priority. It covers common integration patterns with prebuilt and custom options and has a notable presence in manufacturing. It suits teams that want a capable iPaaS without enterprise-tier weight.
8. SAP Integration Suite
SAP Integration Suite is the best fit for SAP-centric organizations that want the deepest, vendor-native SAP connectivity. It offers prebuilt integration packs, API management, and event-driven integration across SAP and non-SAP systems. It is the natural choice when SAP is the center of your landscape and you want SAP’s own platform governing it.
Native-integration platforms
9. Sana Commerce
Sana Commerce is the best fit for teams that want the integration built into the storefront, with a B2B web store that runs on live ERP data rather than a separate middleware layer. Because the commerce platform and the ERP connection come together, there is no separate connector to license. It suits distributors that want an ERP-native store and are choosing a platform, not just a pipe.
10. WizCommerce
WizCommerce is the best fit for B2B wholesalers and distributors that want to skip separate integration software, with native ERP integration built into the commerce platform and a sales rep app alongside it. WizCommerce connects natively to NetSuite, SAP Business One, Dynamics 365, Sage, and more, keeping the ERP the system of record while WizShop, WizOrder, WizPay, and Ella handle the storefront, rep ordering, payments, and AI order entry. There is no middleware to license or maintain, so it fits wholesalers who want commerce and integration in one rather than a connector for an existing store.
11. k-eCommerce and commercebuild
k-eCommerce and commercebuild are the best fit for Microsoft Dynamics Business Central teams that want a webstore with the BC integration built in. Both are native-integration platforms for Business Central that bundle the storefront and the ERP connection. They suit BC distributors who want a complete, pre-integrated store rather than assembling a platform plus a connector.
The three ways to integrate B2B e-commerce with your ERP
There are three ways to integrate B2B e-commerce with an ERP: a dedicated e-commerce-ERP connector, a general-purpose iPaaS, or a native-integration commerce platform where the connection is built in. All three show up on real distributor shortlists, and the right one depends on whether you are connecting an existing storefront or choosing a new platform, and who will maintain the integration afterward.
1. Dedicated e-commerce-ERP connectors
Dedicated connectors are purpose-built for specific e-commerce and ERP pairs, with prebuilt flows that activate without custom development. Tools like Celigo, APPSeCONNECT, and DCKAP Integrator fall here. They launch faster than building from scratch and handle common flows like order, inventory, and pricing sync, and they remain a separate layer you license and maintain alongside your storefront.
2. General-purpose iPaaS
General-purpose iPaaS platforms connect almost any system, not just e-commerce and ERP, through a large library of connectors and a visual builder. Boomi, MuleSoft, Workato, and Jitterbit are the broad players. They are powerful and flexible, which is exactly why they can be heavier and costlier than a focused connector for a single e-commerce-to-ERP use case, and they usually need someone to own the flows long term.
3. Native-integration platforms (no separate middleware)
Native-integration platforms build the ERP connection into the commerce platform itself, so there is no separate middleware to license or maintain. WizCommerce, Sana Commerce, k-eCommerce, and commercebuild work this way. You are choosing a B2B platform and the integration comes with it, which suits teams that want commerce and integration handled together rather than a pipe between two separate systems.
What to look for in ERP integration software
Good ERP integration software offers prebuilt connectors for your specific ERP, real-time or near-real-time bi-directional sync, support for B2B logic like contract pricing, clear ownership of maintenance, and monitoring with automatic retries. The fit depends less on connector counts and more on whether it covers your ERP and your workflows, and who maintains it after go-live.
1. Prebuilt connectors for your ERP
The software should have a prebuilt, supported connector for your exact ERP, not a generic adapter you configure from scratch. A platform with a deep NetSuite library may have no real Prophet 21 connector, and vice versa. Confirm your ERP is a first-class, prebuilt integration, since custom work is where time and cost escape.
2. Real-time, bi-directional sync
The software should sync in real time or on a frequent delta in both directions, not as a once-a-night batch. Batch sync leaves a window where the storefront and the ERP disagree, which is how overselling happens. Bi-directional means orders flow to the ERP and stock and pricing flow back, with the ERP as the system of record.
3. B2B logic, maintenance, and total cost
The software should carry B2B logic like customer-specific pricing and large catalogs, and you should be clear on who maintains the integration and what it costs over time. Look past the license to implementation, connector fees, and the engineering or partner time to keep flows running. The cheapest tool to buy can be the most expensive to own.
iPaaS vs. native integration: which approach is right?
Choose an iPaaS or connector when you want to keep your existing storefront and connect it to your ERP, and choose a native-integration platform when you are picking a new B2B platform and would rather not maintain a separate integration at all. Both keep your data in sync. The real question is whether you are buying a pipe between two systems or a platform that already includes the pipe.
| Consideration | iPaaS or connector | Native-integration platform |
|---|---|---|
| What it is | Software that connects your storefront and ERP | A commerce platform with the ERP integration built in |
| You still need | A separate storefront or platform | Nothing extra; it is the storefront |
| Maintenance | You or an integrator maintain the flows | The vendor maintains the integration |
| Best when | You have a storefront you want to keep | You are choosing a new B2B platform |
| Cost shape | Platform plus connector plus upkeep | One platform fee |

How to choose ERP integration software
To choose ERP integration software, start from your ERP and the systems you need to connect, decide whether you are keeping your storefront or choosing a new platform, and confirm who will own the integration after go-live. That sequence settles the approach before you ever compare feature lists.
Confirm the tool has a prebuilt, supported connector for your exact ERP. Decide whether you are connecting an existing store, which points to a connector or iPaaS, or choosing a new B2B platform, which points to a native-integration platform. Then name who maintains the flows: an internal team, a partner, or the vendor. Run a real order, a stock update, and a pricing change through a trial before you sign, and the shortlist narrows itself.
Where WizCommerce fits
WizCommerce fits B2B wholesalers who would rather not run a separate piece of integration software at all, because the ERP integration is native to the commerce platform. In most wholesale shops, the integration question shows up as a maintenance burden: a middleware subscription to renew, flows to babysit, and orders still getting rekeyed when something drifts. WizCommerce removes that by building the ERP connection into the platform and keeping the ERP the system of record.
WizCommerce connects natively to NetSuite, SAP Business One, Dynamics 365, Sage, and more, with WizShop, WizOrder, WizPay, and Ella covering the storefront, rep ordering, payments, and AI order entry. It fits teams choosing a B2B platform, not teams that only need to connect an existing store.

FAQs on B2B e-commerce ERP integration software
1. What is B2B e-commerce ERP integration software?
B2B e-commerce ERP integration software connects your online store to your ERP so customers, products, pricing, inventory, and orders sync automatically instead of by hand. It comes in three forms: dedicated e-commerce-ERP connectors, general-purpose iPaaS platforms, and native-integration commerce platforms where the connection is built in.
2. What is the difference between an iPaaS, a connector, and a native integration?
An iPaaS is a general platform for connecting many systems; a dedicated connector is purpose-built for specific e-commerce and ERP pairs; and a native integration is built into a commerce platform, so there is no separate tool to license. iPaaS offers the most flexibility, connectors offer prebuilt speed, and native integration removes the middleware layer entirely.
3. What is the best ERP integration software for NetSuite?
For NetSuite, Celigo is the most established e-commerce iPaaS, with APPSeCONNECT and Boomi as alternatives if you run other ERPs too. If you would rather not maintain a separate connector, a native-integration platform like WizCommerce builds the NetSuite sync into the B2B storefront.
4. What is the best ERP integration software for SAP and Dynamics?
For SAP, SAP Integration Suite offers the deepest native connectivity, and APPSeCONNECT is a strong mid-market option for SAP Business One. For Dynamics 365 and Business Central, APPSeCONNECT and native-integration platforms like WizCommerce, Dynamicweb, and k-eCommerce are common choices.
5. What are the best Celigo alternatives?
The best Celigo alternatives are other e-commerce-ERP iPaaS like APPSeCONNECT, Jitterbit, and Boomi, the distribution-focused DCKAP Integrator, and native-integration platforms like WizCommerce and Sana Commerce that remove the need for a separate connector. APPSeCONNECT and Jitterbit are common like-for-like mid-market swaps.
6. How much does ERP integration software cost?
ERP integration software is usually a platform or connector subscription plus implementation. iPaaS pricing is often custom and scales with flows, connectors, and volume, with some platforms starting in the hundreds per month and enterprise deployments running much higher. Native-integration platforms fold the connection into the platform fee.
7. Do real-time and batch sync matter when choosing integration software?
Yes. Real-time or near-real-time sync keeps inventory and pricing accurate and prevents overselling, while batch sync updates on a schedule and leaves a window where systems disagree. For B2B storefronts, prioritize software that supports real-time or frequent delta sync for stock and orders.
8. Do I need middleware to connect my ERP and e-commerce?
Not always. If you are keeping an existing storefront, a connector or iPaaS is the usual path. If you are choosing a new B2B platform, a native-integration platform builds the ERP connection in, so there is no separate middleware to license or maintain.
