SAP Business One Ecommerce Integration: Shopify, Magento and BigCommerce

Last updated: November 4, 2026 · Independent buyer’s guide · We do not sell rankings or coverage.

SAP Business One ecommerce integration means connecting your storefront to SAP Business One so that web orders become sales orders, stock levels flow back to the store, and prices come from SAP price lists instead of being typed in twice. For Shopify, Magento (Adobe Commerce) and BigCommerce, you choose between a multi-platform integration service such as APPSeCONNECT, a platform-specific extension such as the Webkul or Firebear connectors for Magento, or an ERP-native B2B storefront such as Sana Commerce. The right choice depends less on the storefront than on how complicated your SAP pricing is and whether you sell to businesses.

Key takeaways

  • Most current connectors use the Service Layer, SAP’s REST and OData API. Confirm it is installed before you compare products.
  • Price sync is the hardest part. SAP checks blanket agreements, special prices, discount groups and period or volume discounts before the price list, and many connectors send only one price list.
  • Published prices: APPSeCONNECT templates from $99 per month, the eShopSync Shopify app at $99 per month, Webkul’s Magento connector from $1,999 and Firebear’s Magento add-on at $4,999. B2B scope is usually quoted separately.
  • Shopify B2B is available on all plans, but non-Plus plans are limited to three active catalogs. BigCommerce B2B Edition and Adobe Commerce B2B are both sold on custom pricing.
  • Budget for SAP licenses. Sana Commerce lists Indirect Access licenses for its Service Layer connection and says informing you about them is your SAP reseller’s responsibility.

How SAP Business One ecommerce integration works

An integration moves a small set of objects between the two systems, on a schedule or when an event occurs. In SAP Business One these are items, warehouse stock, price lists, Business Partners and contacts, sales orders, incoming payments, deliveries and A/R documents. On the storefront they map to products, inventory locations, catalogs, customer or company accounts, orders and shipments.

The technical route into SAP is usually the Service Layer. SAP’s own training material describes it as a REST API that follows OData standards and supports OData versions 3.0 and 4.0 (SAP Learning, no date shown). Older connectors and on-premises add-ons may still use the DI API. APPSeCONNECT, for example, says it uses the Service Layer where the SAP version supports it and the DI API for older environments (APPSeCONNECT, no date shown).

In a typical setup, SAP is the master for items, stock and prices, and the store is the master for new orders, which become SAP sales orders. When the warehouse posts a delivery with a tracking number, the connector marks the web order as shipped. Our guide to the software needed to run an ecommerce business covers the other layers of the stack.

Where SAP Business One ecommerce integrations go wrong

Available stock is defined differently in each system

SAP Business One tracks In Stock, Committed and Ordered quantities per warehouse, and the connector decides which figure the store sees. APPSeCONNECT lets you send In Stock, In Stock minus Committed, or In Stock minus Committed plus Ordered (APPSeCONNECT, no date shown). The wrong choice causes overselling when phone and EDI orders commit stock in SAP between sync runs. Our article on inventory allocation rules in ERP explains soft and hard reservations in more detail.

SAP pricing has more layers than the store

SAP Business One looks for the most specific price first. According to SAP, it checks a valid blanket agreement, then special prices for the Business Partner, then discount groups, then period and volume discounts on the price list, and only then the base price list (SAP Learning, no date shown). Special prices can carry validity periods and quantity scales, and discount groups can apply by item group, property, manufacturer or item.

Many connectors send only one price list as the storefront base price. That works for a B2C store. It fails for wholesale buyers who expect their contract price online, because the store shows the list price while SAP prices the order at the special price, and the totals no longer match.

Customers, companies and contacts do not map one to one

A B2C shopper becomes a new Business Partner or posts to a shared web customer account. A B2B buyer is a contact under a company Business Partner with ship-to addresses, payment terms and a credit limit. If the connector cannot map Business Partners to company accounts, your B2B portal cannot show who may order on account.

Licensing and infrastructure are left out of the quote

Several connectors require the Service Layer, which some SAP Business One installations do not run. Webkul charges $3,000 to install it for you (Webkul, last updated October 28, 2026). Sana Commerce’s guidance for a Service Layer connection lists an Indirect Access Instance license (one-time fee plus yearly enhancement), a Professional User license for installation and an Indirect Access User license for the add-on account (Sana Commerce, September 2020). Sana calls this an example and says informing the customer about these licenses is the SAP reseller’s responsibility, so treat it as a question for your partner.

How software handles it: three types of connector

Integration platforms with prebuilt templates. These run outside both systems. APPSeCONNECT publishes Shopify, BigCommerce and Magento flows for SAP Business One. Its Shopify flow covers orders, payments, stock by warehouse, items and a price list, Business Partners as companies and contacts, customer-specific price lists for B2B, returns, refunds and tracking. B2B flows, multiple stores and custom rules are scoped separately (APPSeCONNECT, no date shown). Its strength is breadth across channels; the limitation is a third-party runtime billed per plan and process flow.

Platform-specific extensions. These install in the storefront, usually Magento, and connect directly to SAP. Firebear’s SAP Business One add-on for Magento 2 is the most detailed on pricing objects: it maps price lists to retail prices, period discounts to special prices, volume discounts to tier prices, discount groups to catalog and cart price rules, and Business Partners to Adobe Commerce B2B companies (Firebear Studio, no date shown). Webkul’s connector is cheaper but describes exporting categories, products, customers and orders from Magento 2 to SAP, with a price list selected at product creation (Webkul, last updated October 28, 2026). On Shopify, the eShopSync app listing describes syncing SAP items as products and item groups as categories, and does not mention orders or inventory on the listing itself (Shopify App Store, launched October 20, 2023).

Partner-built connectors and ERP-native storefronts. i95Dev sells a subscription connector for Adobe Commerce and Magento Open Source that syncs orders, inventory, tier prices, customer groups, credit limits, invoices and payments, and it requires a component on both sides (Adobe Commerce Marketplace, last updated June 30, 2026). For BigCommerce, Third Wave Business Systems offers a BizWeaver app covering products, inventory, orders, customers and tracking; the listing warns it may not be fully compatible with multi-storefront (BigCommerce App Marketplace, last updated December 8, 2022). Sana Commerce takes a different route: it provides its own B2B web store (Sana Commerce, no date shown) that exchanges products, inventory, prices, discounts, taxes, customers and sales orders with SAP Business One (Sana Commerce, no date shown). It replaces Shopify, Magento or BigCommerce rather than connecting to them.

B2B portals on each storefront

If you sell wholesale, the storefront’s B2B features decide how much SAP data the connector must carry.

  • Shopify: B2B is available on all plans. Basic, Grow and Advanced plans can have up to three active catalogs across B2B markets, while Plus adds unlimited catalogs assigned to company locations, customer-specific deposits and partial payments (Shopify Help Center, no date shown). If each SAP customer has its own special prices, the three-catalog limit will push you to Plus or to a pricing app.
  • Adobe Commerce: The B2B extension adds company accounts, shared catalogs with per-company prices, negotiable quotes, requisition lists, quick order, pay on account and purchase order approvals (Adobe Experience League, last updated October 1, 2026). Adobe documents it as an extension for Adobe Commerce; on Magento Open Source, confirm which B2B modules your developer will use.
  • BigCommerce: B2B Edition provides company accounts with buyer roles, sales staff quoting, an invoice portal with company payment terms and control over payment methods such as purchase orders. Price lists are an enterprise feature for qualifying stores (BigCommerce Support, no date shown), and the app is sold on custom pricing (BigCommerce App Marketplace, last updated August 21, 2026). APPSeCONNECT’s BigCommerce B2B bundle syncs orders, reserve invoices, payments, stock, tracking and a base price list (APPSeCONNECT, no date shown).

What SAP Business One ecommerce integration costs

Only some vendors publish prices. Where they do not, we say so.

Product Published price Extras Source date
APPSeCONNECT Templates from $99/month (Starter) and $299/month (Growth); Enterprise on quote One-time setup fee and ProcessFlow packs, amounts not published No date shown
eShopSync Shopify app $99/month or $1,070/year Requires Service Layer set up by your SAP provider Launched October 20, 2023
Webkul Magento connector $1,999 one-time Installation $999.50; Service Layer installation $3,000; Adobe Commerce edition $200 October 28, 2026
Firebear Magento add-on $4,999 Extra entities or changed directions are custom work No date shown
i95Dev, TWBS BizWeaver, Sana Commerce Not published i95Dev is a subscription; TWBS lists upfront cost plus annual maintenance June 30, 2026; December 8, 2022; no date shown

The storefront itself adds to the bill. Shopify Plus starts at $2,300 per month (Shopify, no date shown). BigCommerce lists Core at $29, Growth at $79 and Scale at $299 per month billed annually, with Performance from $1,499 (BigCommerce, no date shown); B2B Edition is priced separately on request. Adobe does not publish Adobe Commerce pricing, and Magento Open Source has no license fee but needs hosting and development.

Illustrative worked example

These figures are an illustration, not data from a real company. A distributor runs Magento Open Source and SAP Business One without the Service Layer, and wants wholesale customers to see contract prices online.

Stock. One SKU shows In Stock 120, Committed 45 and Ordered 60 in the main warehouse. Sending In Stock shows 120 online, which oversells the 45 already promised. In Stock minus Committed shows 75. Adding Ordered shows 135, which only makes sense if you accept backorders against the incoming purchase order. The distributor chooses 75 and holds back 5 as a buffer, so the store shows 70.

Price. The retail price list says $40, and a wholesale customer has a special price of $32 that drops to $30 at 100 units. A connector that sends only the base price list shows $40 to everyone. One that maps special prices to customer and tier prices shows $32 and $30, matching what SAP will calculate.

Year-one connector cost using published list prices. Webkul totals $1,999 plus $999.50 installation plus $3,000 Service Layer installation, or $5,998.50, but its published scope is an export from Magento to SAP that does not mention customer-specific pricing. Firebear is $4,999 and covers the pricing objects, but its page does not say which SAP interface it uses, so the distributor still needs its SAP partner to confirm the interface and licenses. Neither total includes SAP licenses or the partner’s time.

Our independent take

Start with your SAP pricing, not your storefront. If you sell retail from one price list, most connectors here will work and the choice comes down to cost and support. If wholesale customers rely on special prices, discount groups or volume breaks, shortlist only connectors that map those objects, and ask for a demo with your own Business Partner data.

We found no connector that publishes complete B2B pricing for all three storefronts. Firebear documents the deepest Magento price mapping, APPSeCONNECT covers the widest set of platforms, and Sana Commerce is the strongest fit when you are willing to run its storefront instead of Shopify, Magento or BigCommerce. Ask every vendor for its sync frequency, error queue and retry behavior in writing.

Three buyer scenarios

A consumer brand on Shopify with one warehouse. You need orders, payments, stock and tracking, with one retail price list. A template service such as APPSeCONNECT at its published entry price is a reasonable first quote. Check whether your SAP installation already runs the Service Layer before you count on the vendor’s stated average go-live of less than 24 hours.

A distributor on Magento with contract pricing. Your SAP special prices and volume discounts must appear online. Compare Firebear, i95Dev and APPSeCONNECT on how each maps special prices and discount groups, and decide whether you need Adobe Commerce for its B2B extension or will add B2B modules to Open Source.

A wholesaler moving to BigCommerce B2B Edition. You want company accounts, quotes and an invoice portal tied to SAP A/R. Ask APPSeCONNECT and TWBS how they map Business Partners to company accounts and whether SAP invoices appear in the invoice portal, and confirm multi-storefront support with TWBS given its listing caveat.

When you do not need dedicated software

If you process a few dozen web orders a week, sell from one warehouse and use one price list, a dedicated connector may cost more than it saves. A scheduled export and import of orders and stock, set up by your SAP partner, can be enough at that volume. The trade-off is manual effort and a higher risk of overselling between updates.

The same applies if B2B customers already order through EDI or a sales rep and the website only takes small retail orders. Compare the connector cost with the cost of the errors you see today. Our guide to ERP data integration covers how to decide which data must be in sync and which can wait.

How we researched this

We reviewed the ranking guides from Experlogix and Satva Solutions, which both sell integration products or services. We then read the documentation, marketplace listings and pricing pages for each connector named here, SAP’s training material on the Service Layer and pricing, and the B2B documentation from Shopify, Adobe and BigCommerce. Every price and capability links to its source with the date shown. We have no commercial relationship with any vendor in this guide.

Frequently asked questions

Does SAP Business One have a built-in Shopify or Magento connector?

Every Shopify, Magento and BigCommerce connector we reviewed is sold by a third-party developer or SAP partner, not by SAP. These products connect through the Service Layer or, for older versions, the DI API. Your SAP partner can tell you which interface your version supports.

How much does an SAP Business One Shopify integration cost?

Published entry prices start at $99 per month for APPSeCONNECT templates and the eShopSync app. B2B flows, extra stores and setup are usually quoted separately, and you should also allow for SAP licenses and your Shopify plan.

Can customer-specific prices from SAP Business One show on my web store?

Yes, but only if the connector maps SAP special prices, discount groups and period or volume discounts to the storefront’s B2B pricing. Firebear documents this mapping for Magento, and APPSeCONNECT lists customer-specific price lists for Shopify B2B. Many simpler connectors send only one base price list.

Is Shopify B2B enough for an SAP Business One distributor?

Shopify B2B is available on all plans, but Basic, Grow and Advanced allow only three active catalogs across B2B markets. If many customers have their own SAP prices, you will likely need Shopify Plus, which starts at $2,300 per month, or a different pricing approach.

How often should stock sync between SAP Business One and the store?

It depends on how fast stock moves and how many channels commit stock in SAP. Fast movers sold by phone or EDI as well need event-based or very frequent updates, while slow movers can sync on a schedule. In either case, send In Stock minus Committed rather than on-hand stock.
