What if your online store could talk perfectly to your back office?
When a customer places an order, everything just “clicks”: inventory is updated, invoices are issued, and shipments are scheduled automatically. No more manual processes like data entry, and no more error-prone spreadsheets.
That’s what B2B eCommerce integration does. We’re a Shopify Plus and B2B integration partner, and we plan, build, and support the connections that keep your store and systems in sync.
What does B2B integration really mean?
Integration means connecting your Shopify store to all the other systems you use, your ERP (finance and inventory), warehouse software, shipping platforms, payment processors, and more, so they automatically share data.
For example, when a buyer places an order, the system efficiently manages the entire ordering process by checking pricing, reserving inventory, scheduling shipping, creating an invoice, and updating the customer record. Without integration, each step might require manual work or messy spreadsheets. With integration, the flow happens automatically.
As one expert explains, “A B2B ecommerce ERP integration is the process of connecting your ERP system to your B2B ecommerce platform,” unlocking real-time data flow, synchronization, and automation.
In practice, this means fewer mistakes and faster orders. Your store will only show items truly in stock and charge the right prices, so customers get what they expect. The result: enhanced customer satisfaction, more sales, and clear reporting on your performance.
Key integration building blocks
- Store ↔ ERP sync: Sync products, prices, customers, inventory, and orders between Shopify and your ERP (like Business Central, NetSuite, or SAP). Updates in one system automatically appear in the other. This keeps your online catalog in lockstep with your backend, so if the ERP shows an item is out of stock or discontinued, the Shopify store reflects that too.
- B2B checkout & payment terms: Let approved customers check out on net terms (for example, Net 30) or use business credit providers. These orders integrate directly into your accounts receivable. You can even store customer credit cards on file and invoice them automatically. Shopify lets you set up these net payment terms and streamlined invoices out of the box.
- PunchOut catalogs: For enterprise buyers (SAP Ariba, Coupa, etc.), we set up a PunchOut connection. Buyers browse your Shopify site from within their procurement system; when they check out, the order is sent back as a purchase order into their system and into your ERP. This means big customers can shop your site without manual catalog uploads or re-keying orders.
- EDI: If large customers or warehouses require EDI (with 850/856/810 documents), we handle it. Electronic Data Interchange automatically exchanges purchase orders, advance ship notices, and invoices between trading partners. For example, a customer’s EDI PO can become an order in Shopify, and your system can send back the 856 shipping notice and 810 invoice automatically.
- E-invoicing & compliance: Many countries (especially in Europe and Latin America) require structured electronic invoices. We connect to networks like PEPPOL (a global e-invoicing framework) so your invoices always meet local regulations and flow straight into government or customer systems.
Shopify-friendly B2B patterns
Because we’re Shopify Plus partner, we use features that save you time:
- Company-specific pricing & catalogs: Show each buyer the products and prices meant just for them. Shopify lets you create custom catalogs and price lists per customer.
- Terms at checkout: Enable special payment terms (Net 30, Net 45, etc.) so trusted customers can order now and pay later. These tie neatly into your AR.
- Global selling made easy: Shopify handles multiple currencies, tax rates, and duties out of the box, so you can sell internationally without extra work.
- Connect once, reuse often: We build integrations that scale. As you add new warehouses, marketplaces, or systems, the connections can be extended or reused.
Collaborating with a Shopify B2B eCommerce development agency helps smart brands achieve seamless integrations, ensuring smoother workflows and scalable digital growth.
How your systems talk
Think of all your systems like people in a group chat. Each one sends messages that the others understand:
- Shopify: “Order #123 from ACME, 2 pallets of filters.”
- ERP: “Inventory reserved, invoice created, scheduled to ship Friday.”
- Warehouse: “Packed and shipped, tracking #XYZ.”
- Shopify: (Automatic) “Order #123 shipped. Email sent to ACME with tracking info.”
We set up this “chatroom” and wrote the rules so each system understands the others. You don’t have to worry about translations; we handle them. Every order and update flows to every system that needs it.
Handling tricky cases
We also handle the complex stuff behind the scenes:
- Multiple price lists: Customers can have their own price books and still get promotions, without conflicts.
- Complex orders: Backorders, partial shipments, or split deliveries are all tracked and fulfilled correctly.
- Returns and refunds: Order changes or refunds automatically update in finance and inventory.
- Big-buyer workflows: We support approval steps, purchase order matching, and PunchOut workflows for enterprise buyers.
- Local regulations: Country-specific e-invoicing rules or tax requirements (like PEPPOL) are built into the process.
- Multi-channel sales: We can integrate orders from other online channels (Amazon, third-party marketplaces, etc.) so all orders funnel into your ERP consistently.
Keep your back-office systems in sync
With our b2b eCommerce solutions, all parts of your business stay connected:
- ERP (finance & inventory): Microsoft Business Central, NetSuite, SAP, or any ERP you use. We keep orders and inventory data synced.
- Warehouse/Logistics: 3PLs and WMS/shipping systems automatically update stock levels and fulfillment status.
- CRM & Sales Tools: Customer profiles and orders remain consistent whether viewed in Shopify, CRM, or sales dashboards.
- Tax & compliance: Electronic invoicing networks (like PEPPOL) and audit logs are part of the workflow.
In fact, when your ERP and ecommerce platform are integrated, all data lives in one place so reporting and tax compliance become much simpler.
Smarter B2B checkout and credit
Offer checkout terms that fit B2B. For trusted B2B customers, you can set up net payment terms (for example, Net 30 means pay within 30 days). You can also add B2B financing or credit partners so customers can buy on credit without exposing you to risk.
Either way, all orders and invoices tie back into your AR and ERP, so you always know who owes what. Shopify even lets you store credit cards on file and requires purchase order numbers at checkout to streamline your process.

What It Looks Like:
Here’s what this all looks like in action:
- B2B portal with terms: Distributors log in, see their custom pricing, and checkout on Net-30 terms. The order shows up in ERP and reserves stock.
- PunchOut for enterprise: A buyer in Ariba clicks a link and shops your Shopify catalog. At checkout, the order is returned to Ariba for approval and then processed in your ERP.
- EDI at scale: Big customers send POs as EDI 850 files; your system automatically returns the 856 shipping notice and 810 invoice by EDI. No email ping-pong or retyping.
- Tax compliance: Your store automatically handles international tax and invoicing rules. For example, Shopify can calculate EU VAT and issue a PEPPOL-standard e-invoice to the buyer's system.
By leveraging the right B2B eCommerce solutions, smart brands can streamline integration processes, reduce complexities, and deliver seamless customer experiences.
Quick RFP checklist
When planning your integration, consider these questions:
- Which systems need to connect? (ERP, WMS/3PL, CRM, tax engines, etc.)
- Which customers need special pricing or payment terms?
- Do you need PunchOut catalogs, EDI, or e-invoicing? (e.g., Ariba PunchOut, Coupa, SAP, PEPPOL, etc.)
- What’s the rollout plan? (Which integration goes live first, and what can wait?)
- Who will support and monitor the integration after launch?
