What Is ERP eCommerce Integration? [2026]

There is a treasure-trove of information locked within ERP and ecommerce platforms which, when synced, can unlock and host of new opportunities for businesses. If your online store doesn’t talk to your ERP, CRM, and inventory systems, someone on your team is stuck re-typing data between them. That’s what eCommerce integration fixes. This guide covers what it is, the main methods, best practices, common questions, and why it matters most for distributors and manufacturers specifically.

What is ERP eCommerce Integration?

eCommerce integration connects your online storefront to the back-end systems that actually run your business: ERP, inventory, CRM, shipping, accounting, PIM, and EDI. Once connected, data like orders, pricing, and stock levels flows automatically between systems instead of being entered by hand in five different places.

For distributors and manufacturers, this isn’t a nice-to-have. Catalogs run into tens of thousands of SKUs, pricing varies by customer contract, and orders need to hit the ERP the moment they’re placed. Manual entry doesn’t scale to that.

ERP – eCommerce Integration: Steps Involved

1. Data sources

First, you need to understand the type of data sources you’ll use. This matters because it can help you decide what type of integration will work best.

Cloud-based: Most of today’s ERP and eCommerce platforms are based in the cloud and use a software-as-a-service (SaaS) integration model. These are easiest to integrate since they have universal connectors that can be integrated into other modern platforms.

On-premise: This is a back-office ERP platform that’s run off local hardware. While you can integrate with this type of system, it tends to be legacy software that presents new challenges.

Hybrid: Some businesses use a combination of tools, like a cloud-based eCommerce site and an on-premise ERP platform.

2. Methods for ERP – eCommerce Integration

You can set up an ERP integration using one of three different methods.

Point-to-point integration

Two systems are connected directly through custom code.

• Pros: full control over logic, no middleware cost, works fine for one connection
• Cons: doesn’t scale, each new system is its own project, becomes a tangle of custom code to maintain
• Best for: businesses with exactly one or two systems to connect and no plans to add more

Middleware / Integration Platform 

A middle layer sits between all your systems and manages the data flow centrally. It’s the model behind platforms like DCKAP Integrator, which routes everything through one hub instead of a web of one-off connections.

• Pros: scales easily as you add systems, one place to monitor and manage everything, less custom code overall
• Cons: adds a platform to learn, ongoing subscription cost
• Best for: distributors and manufacturers running multiple systems (ERP, CRM, eCommerce, marketplaces) that need to stay in sync long-term

API-based integration

Systems exchange data directly through APIs in real time.

• Pros: fast, real-time, reliable when APIs are well-documented
• Cons: depends entirely on both systems having stable, modern APIs, which older ERPs sometimes lack
• Best for: connecting modern, API-friendly platforms where you want direct, low-latency data flow

Pre-built connectors

Ready-made integrations for common systems (Shopify, BigCommerce, NetSuite, Epicor, Salesforce, and so on) that cut setup time from months to weeks.

• Pros: fastest to deploy, less development cost, tested and proven configurations
• Cons: less flexible for unusual or highly custom workflows without added configuration
• Best for: businesses connecting popular, widely-used systems and wanting to go live quickly rather than building from scratch

3. Types of data to transfer

Before starting with an eCommerce integration  you should decide what data to transfer and in which direction it will move. For example, you might only want order information to flow from your web store to your ERP system.

Some of the most common types of data to transfer include:

• Product information
• Customer data
• Pricing
• Shipping
• Inventory levels
• Order/invoice information
• Taxes
• Returns

4. Process for setting up an ERP – eCommerce integration

Here are the steps we recommend for setting up an ERP integration with your ecommerce system:

Now that you know what to look for, let’s examine the steps to successful ERP eCommerce integration.

1. Establish clear goals. Both front-end and back-end parties should have a clear understanding of what they hope to achieve from the integration.
2. Define the business processes to integrate. Make sure that both ERP and eCommerce systems can handle the necessary tasks.
3. Map out the data flows. This will help ensure that data is transferred correctly and efficiently between systems.
4. Test thoroughly before going live. Run several tests of the data integration process before moving into a live deployment. This will help ensure that there are no errors and that the systems are working properly together.
5. Plan for post-integration support and maintenance. Systems will inevitably go down occasionally, so make sure you have someone who can troubleshoot issues and get the systems up and running again as quickly as possible.

But deciding to integrate your ERP and eCommerce systems is only the first step. You’ll also need to understand common challenges and best practices to overcome these issues.

Challenges with ERP Integration with eCommerce

There are many issues you may face when integrating ERP and eCommerce systems. Some of them are on the human side, others are on the side of your integration software, and still others depend on the software you’re already using.

Here are some of the most common:

Scaling

Before embarking on an integration, ensure your existing eCommerce system and ERP solution can handle the integration’s data flow requirements. Most modern solutions shouldn’t hit any snags, but you want to ensure you don’t discover bottlenecks or slow down business operations midway through.

Budgeting

It’s easy for an integration project to go over budget, but the solution usually lies in planning. To prevent unexpected problems, develop a very clear plan ahead of time, so your integration can happen smoothly.

Custom integrations

Many ERP systems and online stores have bespoke features tailored to business needs. These can make integration more challenging since the usability isn’t the same as the software out-of-the-box. It also means updates and changes aren’t straightforward since there are custom features to support.

Older software

Outdated apps or legacy on-premise solutions can be challenging to integrate. If you’re considering upgrading to a cloud platform, this can make a big difference in how easily and quickly you can get started with your integration.

Multiple data types

The more data types you’ll need to integrate, the more complex the system will be. Look to simplify whenever possible. Making choices now to streamline your data flows will make it even easier to implement a smart integration.

eCommerce – ERP Integration Best practices

These best practices can help you avoid common challenges and ensure your integration process is a smooth one.

Choose the right integration solution

Using cron jobs, writing code, or even worse—manually transferring data between applications—can impact every aspect of your business.

Your eCommerce website and ERP platform are complex systems, so invest the time to choose an integration that works for your unique needs. Look for a tool that integrates with the platforms you rely on and has experience launching these very integrations.

Communicate with all stakeholders

An integration can affect almost everyone in your business, so ensure everyone is up to date with what’s happening. Explain how each sales channel will be impacted and what the integration will mean for the productivity of each department and the business as a whole. Work to get buy-in before moving forward with the live integration.

Choose the appropriate level of security

Look for an integration solution that provides the level of data security you need. A common misconception is that on-premise solutions are more secure. While they frequently provide more control over security settings, the reality is that cloud-based iPaaS applications usually have stricter protocols and follow more robust data compliance measures.

Find a partner that offers support

While most integrations happen seamlessly, even the small probability of an issue along the way matters when it impacts your offline and online business processes. Look for a solution that can auto-troubleshoot issues and has a 24/7 support team to ensure everything runs smoothly.

FAQs

Do I need developers on staff to manage integrations?

Not if you’re on a low-code platform with pre-built templates and a visual dashboard. You’ll still want technical support available for edge cases and custom logic. DCKAP offers the additional benefit of leaving the implementation and customization to its team of experts.

What’s the difference between iPaaS and a direct API integration?

Direct API integration connects two systems only. iPaaS acts as a hub connecting many systems, which matters once you’re managing ERP, CRM, eCommerce, and EDI all at once.

Can integration handle customer-specific pricing?

Yes, and it should. Contract pricing, tiered discounts, and customer-specific catalogs should sync automatically rather than being managed manually at checkout.

How much does eCommerce integration cost?

It depends on the method. Point-to-point custom builds tend to cost more over time due to ongoing maintenance. iPaaS platforms with pre-built connectors usually cost less upfront and scale more predictably as you add systems. DCKAP’s pricing starts at $1,250 per month.

Which integration method should I choose?

For a single, simple connection, direct API or point-to-point can work. For anything involving multiple systems (ERP, CRM, eCommerce, marketplaces), an integration platform is generally the better long-term choice for distributors and manufacturers.

Is EDI still relevant with modern APIs available?

Yes. Many retail and distribution trading partners still require EDI compliance, so it typically runs alongside API-based integrations rather than being replaced by them. DCKAP offers a way for users to connect critical EDI data with the ERP along with its robust EDI management features.
