Key Capabilities of B2B Integration Solutions

While specific functionality varies by vendor, leading B2B integration solutions typically offer the following core capabilities:

Data Mapping and Transformation

The foundation of any B2B integration is data mapping – defining how information in one system or format corresponds to another. B2B integration tools provide graphical interfaces and pre-built adapters to simplify field-level mapping between common standards and protocols, such as:

  • XML
  • Flat files (e.g. CSV, TXT)
  • APIs (e.g. REST, SOAP)

Advanced solutions use AI to automatically recommend mappings based on similar partner configurations or back-end systems.

Business Process Orchestration

In addition to data exchange, B2B integration tools enable the automation of end-to-end business processes across internal and external systems. Visual orchestration tools allow users to define workflows based on business rules, exception handling, and approval routing.

For example, an order-to-cash process could involve the following automated steps:

  1. Receive purchase order from customer via EDI
  2. Validate order against inventory system via API
  3. Send order confirmation to customer via EDI
  4. Create sales order in ERP system
  5. Send shipping notice to customer via EDI when order ships
  6. Generate and send invoice to customer via EDI
  7. Post receivable in accounting system when payment is received

Partner Management

B2B relationships introduce unique management challenges, as each partner may have different integration requirements, SLAs, and communication preferences. B2B integration solutions provide portals and self-service tools to streamline partner onboarding, monitoring, and incident management.

Key capabilities include:

  • Partner profiles and agreement management
  • Self-service partner onboarding and testing
  • Real-time transaction monitoring and error alerting
  • Customizable SLA and KPI tracking
  • Secure document and data exchange

The goal is to make B2B integration as frictionless as possible for partners while providing centralized governance and control.

Security and Compliance

Securing B2B transactions and ensuring compliance with data privacy and industry regulations is critical. B2B integration solutions provide a range of security and governance features, such as:

  • Encryption and secure protocols for data in transit and at rest

According to Deloitte, 55% of organizations view B2B integration as an important part of their overall cybersecurity strategy.

B2B Integration Patterns and Use Cases

B2B integration spans a variety of industries and business functions. Let‘s explore some common patterns and use cases.


The procure-to-pay process involves the exchange of numerous documents between buyers and suppliers, from RFQs and purchase orders to invoices and payments. B2B integration digitalizes and automates this process:

  1. Buyer sends RFQ to supplier via supplier portal or B2B network
  2. Supplier responds with quote via portal or B2B network
  3. Buyer creates purchase order in procurement system, which is automatically sent to supplier via EDI or B2B network
  4. Supplier confirms receipt of PO and sends order acknowledgment via EDI or B2B network
  5. Supplier sends invoice to buyer via EDI or B2B network
  6. Buyer‘s AP system automatically matches invoice to PO and receipt, and initiates payment to supplier via B2B payment network or bank transfer

A Hackett Group study found that organizations with high levels of P2P automation and integration have 72% lower transaction costs and 50% faster cycle times than their peers.


The order-to-cash process is the flip side of procure-to-pay, encompassing the steps from receiving a customer order to collecting payment. B2B integration enables straight-through processing of orders:

  1. Customer sends purchase order via EDI, B2B portal, or ecommerce site
  2. Order automatically flows into seller‘s ERP system and is validated against inventory and pricing rules
  3. Order confirmation is automatically sent back to the customer via EDI or portal
  4. Shipping notice is automatically sent to the customer via EDI or portal when order ships
  5. Invoice is automatically generated and sent to the customer via EDI, portal or AP network
  6. Payment is automatically applied to invoice in seller‘s AR system when received

According to APQC, top performers process sales orders 80% faster and with 73% higher accuracy than bottom performers, largely due to B2B integration and automation.

3PL Integration

Many companies outsource logistics to third-party logistics (3PL) providers. B2B integration enables real-time data exchange between the company and 3PL to ensure smooth order fulfillment:

  • Company sends orders to 3PL‘s warehouse management system (WMS) via EDI or API
  • 3PL sends inventory updates and stock levels back to company via EDI or API
  • 3PL sends shipping notices and tracking info to company via EDI or API
  • Company and 3PL exchange invoices and payments via EDI or B2B payment network

Best-in-class companies are 69% more likely to have integrated order management and 3PL systems than their peers, enabling them to deliver orders 72% faster.

Healthcare Supply Chain

The healthcare industry has unique B2B integration requirements due to complex supply chains, regulatory requirements (e.g. HIPAA), and the need to exchange sensitive patient data. Common integration scenarios include:

  • Hospitals exchanging purchase orders and invoices with suppliers via EDI (often using the ANSI X12 4010 standard)
  • Pharmacies exchanging e-prescriptions and insurance claims with payers and providers via APIs
  • Labs exchanging test orders and results with providers via HL7 interfaces
  • Manufacturers exchanging product data and serialization info with distributors via GS1 standards

According to GHX, healthcare providers that automate supply chain processes can reduce costs by 40% and improve fill rates by 25%.

These are just a few examples of how B2B integration is transforming processes across industries. As digital ecosystems continue to expand, the need for seamless integration will only accelerate.
