E-Commerce to ERP Integration for Manufacturers
E-commerce to ERP integration synchronizes product catalog, customer-specific pricing, available inventory, orders, and shipment status between a storefront - Shopify Plus, BigCommerce, Adobe Commerce, or a custom B2B portal - and an ERP such as Infor SyteLine, LN, or M3. Manufacturer requirements differ sharply from retail: contract pricing per customer, quantity break tiers, credit terms, made-to-order and configurable items, and partial shipments are the norm rather than the exception. This guide covers the five data flows that matter and where manufacturer-specific complexity actually bites.
The Five Flows E-Commerce to ERP Integration Must Cover
Product and catalog data flows from ERP to storefront: item numbers, descriptions, UOM, weights, and which items are even web-eligible. Pricing flows from ERP because contract pricing lives there, not in the storefront. Inventory availability flows from ERP, ideally as available-to-promise rather than raw on-hand. Orders flow from storefront to ERP and must land as real sales orders with correct customer, ship-to, terms, and tax treatment. Status flows back - order acknowledged, shipped with tracking, invoiced. Manufacturers who skip the last flow generate a support call for every order, which erases the efficiency the storefront was supposed to create.
Catalog, Contract Pricing, and Configurable Products
Retail platforms assume one price per item per customer group. Manufacturers routinely have negotiated contract prices per customer, quantity break tiers, and promotional effectivity dates, all maintained in ERP. Pushing a full price matrix into the storefront is impractical once you have thousands of customer-item combinations, so the durable pattern calls ERP for a real price at the moment the logged-in customer views or carts the item, with a short cache.
- Call ERP pricing in real time for logged-in B2B customers rather than replicating the price matrix
- Cache prices for 5 to 15 minutes per customer-item pair to keep page loads under a second
- Model quantity break tiers in the cart so the displayed price updates as quantity changes
- Flag web-eligible items explicitly in ERP; never assume every active item should be sellable online
Order Capture, Tax, Credit, and Fulfillment
An order created in the storefront is a document, not yet a commitment. Post it to ERP as a sales order via supported APIs - IDO web services in SyteLine, ION or the relevant business object in LN and M3 - and let ERP apply credit checks, tax determination through Avalara or Vertex, and allocation. Design explicitly for the case where the ERP rejects the order after payment authorization, because it will happen: customer on credit hold, item discontinued, ship-to invalid. That order needs a visible pending state, a notified owner, and a resolution path, not a silent failure in an integration log. Partial shipments also need first-class handling since manufacturers rarely ship everything at once.
Inventory Availability and Real-Time Stock Signals
Publishing raw on-hand quantity to a storefront oversells, because on-hand includes allocated stock, quality hold, and consignment. Publish available-to-promise instead, and for made-to-order items publish a lead time rather than a quantity. Update frequency should follow item velocity rather than a single global schedule, since fast movers need minutes and slow movers do not.
- Publish ATP net of allocations, quality holds, and safety stock - never raw on-hand quantity
- Push updates on inventory transaction events for fast movers; scheduled sync suffices for slow movers
- Show lead time instead of a quantity for made-to-order and configured items
- Reserve inventory in ERP at order acceptance, not at cart add, to avoid phantom allocations
How Netray Connects Storefronts to Infor ERP
Netray builds e-commerce integrations against the ERP's supported API layer with an availability and pricing service in between, so the storefront stays fast without duplicating ERP logic. We implement idempotent order posting keyed on the storefront order ID, so a retry after a timeout cannot create a duplicate sales order - the single most common defect we find in inherited implementations. Our AI agents monitor for pricing drift between storefront cache and ERP, oversell conditions, and orders stuck between systems, alerting before a customer notices. Manufacturers typically move from next-day batch order entry to sub-minute posting with no manual re-keying.
Frequently Asked Questions
How do you integrate Shopify with an ERP like Infor SyteLine?
Use Shopify webhooks for order events and the Admin API for catalog and inventory updates, paired with SyteLine IDO web services for reading pricing and availability and creating sales orders. Place a small integration service in between to hold contract pricing logic and ATP calculation. Post orders idempotently keyed on the Shopify order ID so a retry after a timeout cannot create a duplicate sales order.
Should product prices live in the storefront or the ERP?
In the ERP, for B2B manufacturers. Contract prices, quantity break tiers, and promotional effectivity are already maintained there and replicating thousands of customer-item combinations into a storefront creates constant drift. Call ERP for a real price when a logged-in customer views or carts an item, with a short cache of five to fifteen minutes to keep pages fast. Guest or list pricing can be safely cached longer.
How do you prevent overselling on a manufacturer B2B site?
Publish available-to-promise rather than raw on-hand quantity, netting out allocations, quality holds, safety stock, and consignment. Update fast-moving items on inventory transaction events instead of on a fixed schedule. Reserve inventory in ERP when the order is accepted, not when an item is added to a cart, and display a lead time rather than a quantity for made-to-order or configured products.
