The Three Types of B2B Orders and Why One Still Runs on Email

B2B ordering has evolved—but not evenly. While some orders flow seamlessly through e-commerce portals or structured purchase order systems, others still depend on salespeople manually relaying information between customers and internal teams. These “sales-in-the-middle” orders often rely on emails, spreadsheets, and manual entry, making them slower, riskier, and harder to scale. 

This is where B2B order management automation becomes critical. Understanding the different types of B2B orders helps explain why certain workflows remain stuck in the past—and how modern automated order processing can bring consistency, speed, and accuracy across every order channel. 

What Is B2B Order Management Automation? 

B2B order management automation is the use of software to automatically capture, validate, and process orders from multiple channels into ERP or order management systems. 

Unlike consumer commerce, B2B orders arrive through a mix of: 

• E-commerce portals 

• Email-based PDF purchase orders 

• Sales-led workflows 

• EDI and account-managed processes 

Automation unifies these inputs into a single, controlled workflow. It ensures consistent validation, reduces manual effort, and allows businesses to scale without adding operational complexity. 

The Three Types of B2B Orders 

Most B2B orders fall into one of three categories. Each has very different operational characteristics. 

Type 1: E-Commerce-Driven B2B Orders 

These orders flow through online portals where customers place orders directly. 

Characteristics: 

• Structured data 

• Predefined product catalogs 

• Limited need for manual intervention 

Strengths: 

• Fast processing 

• Low error rates 

• Easy integration with ERP 

Limitations: 

• Not all customers adopt portals 

• Complex pricing and approvals often fall outside ecommerce workflows 

While ecommerce order processing services are effective for standardized transactions, they represent only a portion of real-world B2B volume. 

Type 2: Purchase Order–Driven B2B Orders 

These orders arrive as formal purchase orders, most commonly as PDFs sent via email. 

Characteristics: 

• High order volume 

• Variable layouts and formats 

• Often contain negotiated pricing 

Strengths: 

• Familiar to customers 

• Fits enterprise procurement workflows 

Challenges: 

• Manual data entry 

• High error risk 

• Slow turnaround 

This is where purchase order automation software play a critical role—turning unstructured documents into validated, ERP-ready data. 

Type 3: Sales-In-The-Middle Orders (The Time Warp) 

Sales-in-the-middle orders occur when customers send requests to sales representatives, who then manually re-enter or reformat orders before passing them to operations. 

Characteristics: 

• Emails, phone calls, or spreadsheets 

• Heavy reliance on individual sales reps 

• Manual interpretation and re-entry 

Why These Orders Are Stuck in a Time Warp 

Sales-led workflows often persist because they feel “personal” and flexible. In reality, they introduce major operational issues: 

• Delays caused by back-and-forth communication 

• Increased risk of misinterpretation 

• No standardized validation 

• Heavy dependence on individual knowledge 

Without sales order processing automation, these orders remain disconnected from modern systems. 

Why Sales-In-The-Middle Orders Are the Most Expensive 

Among all three order types, sales-in-the-middle orders are the most costly to process. Key cost drivers include: 

Manual Data Entry 

Sales teams spend time re-typing order details instead of selling. 

Error Propagation 

Mistakes made during re-entry flow directly into ERP systems. 

Lack of Visibility 

Orders sit in inboxes instead of structured systems. 

Poor Scalability 

As volume grows, complexity increases disproportionately. 

This is why many organizations focus on order processing automation to modernize these workflows first. 

How Automated Order Processing Fixes the Gap 

Modern automation does not remove sales teams—it removes friction. 

Step 1: Centralized Order Capture 

Orders from sales emails, PDFs, and portals enter a single system. 

Step 2: Intelligent Extraction 

Automation extracts data regardless of format. 

Step 3: Validation and Control 

All orders are validated against ERP rules. 

Step 4: Exception Handling 

Only unclear orders require human review. 

Step 5: ERP Synchronization 

Clean orders flow directly into fulfilment systems. 

This approach brings sales-led orders into the same operational standard as other channels. 

Manufacturer Modernizing Sales-Led Orders 

Scenario 

A manufacturer receives orders through ecommerce, PDFs, and direct emails to sales reps. 

Before Automation 

• Sales manually re-enter orders 

• Operations fix errors downstream 

• Fulfilment delays are common 

After B2B Order Management Automation 

• Sales emails are processed automatically 

• Orders are validated consistently 

• ERP data remains accurate 

The manufacturer reduces costs while preserving customer flexibility. 

Common Mistakes When Automating Sales-Led Orders 

Treating Sales Orders as “Special” 

All orders should follow the same validation rules. 

Automating Without Sales Buy-In 

Sales teams must see automation as support—not replacement. 

Ignoring Exception Design 

Automation should surface problems, not hide them. 

Over-Reliance on Manual Review 

The goal is exception-only intervention. 

Avoiding these mistakes ensures long-term success. 

Best Practices for Managing All Three Order Types 

To scale effectively with automated purchase orders and sales workflows: 

• Support ecommerce, purchase orders, and sales-led orders equally 

• Apply consistent validation across all channels 

• Automate purchase order intake from PDFs and emails 

• Use automation to assist—not replace—sales teams 

• Monitor accuracy and processing metrics 

These practices create a unified order operation.

FAQs: B2B Order Types and Automation 

Why do sales-in-the-middle orders still exist? 

Because of legacy processes, customer habits, and lack of automation. 

Can automation handle sales-led orders? 

Yes. Modern systems process emails, PDFs, and unstructured inputs. 

Does automation replace sales teams? 

No. It removes administrative work so sales can focus on customers. 

Which order type benefits most from automation? 

Sales-in-the-middle orders typically see the biggest gains. 

How quickly can results be seen? 

Most teams see improvements immediately after deployment.
