Business-to-business (B2B) e-commerce is the sale of goods or services between businesses. It is a much larger market than business-to-consumer (B2C) e-commerce, and it is growing rapidly. In this chapter, we will provide an overview of B2B e-commerce, including its history, benefits, and the role of EDI.

Learning Objectives

By the end of this chapter, you will be able to:

  • Define B2B e-commerce and explain how it differs from B2C.
  • Trace the evolution of B2B from EDI to marketplaces and private networks.
  • Explain the procurement process and how B2B e-commerce changes it.
  • Discuss the benefits, challenges, and state of B2B e-commerce in Nepal.

B2B versus B2C

Feature B2C B2B
Buyer Individual consumer Purchasing staff acting for a company
Order size Small, one item or a few Large and repeated, often bulk
Decision Quick, often emotional Slow, involves several people and approvals
Price Same listed price for everyone Negotiated, contract, or volume-based price
Payment Card, wallet, or cash on delivery Credit terms (for example 30–60 days), bank transfer
Relationship Often one-off Long-term, based on trust and reliability
Documents Order confirmation, receipt Quotation, purchase order, delivery note, tax invoice

1. History of B2B E-commerce

The roots of B2B e-commerce can be traced back to the 1960s, with the development of Electronic Data Interchange (EDI). EDI is the electronic exchange of business documents, such as purchase orders and invoices, between businesses. EDI was originally developed to automate the procurement process, and it is still widely used today.

Stage Period (approx.) What changed
Automated order entry 1970s Suppliers placed terminals or modems at customers’ sites for ordering
EDI 1970s–1980s Standard electronic documents exchanged between partners’ computers
B2B e-commerce websites Mid-1990s Sellers’ online catalogues that any business buyer could use
Net marketplaces Late 1990s E-distributors, e-procurement networks, exchanges, and consortia
Private industrial networks 2000s onward Company-led networks for collaboration across the supply chain
Cloud, APIs, and mobile B2B 2010s onward SaaS procurement, B2B apps for retailers, and system-to-system APIs

The Procurement Process

Procurement is how firms buy the goods and services they need. A typical cycle has seven steps:

  1. Search for suppliers.
  2. Qualify suppliers (check quality, capacity, and reliability).
  3. Negotiate prices, credit terms, and delivery.
  4. Issue a purchase order.
  5. Receive the invoice.
  6. Receive and inspect the goods (shipping and delivery).
  7. Make payment and settle the account.

Each step creates documents and approvals. B2B e-commerce reduces the cost and time of these steps: online catalogues speed up search, electronic purchase orders and invoices replace paper, and matching the purchase order, delivery note, and invoice can be automated.

Worked example: a pharmacy chain

A pharmacy chain with 20 branches in Kathmandu Valley used to phone distributors daily. Orders were sometimes misheard, prices differed between branches, and invoices were checked by hand.

After moving to an online ordering portal shared with its main distributors:

  • Branch managers order from a catalogue with contracted prices, and the head office approves large orders online.
  • Distributors receive clean electronic orders and confirm delivery dates.
  • The finance team matches each invoice to its purchase order automatically, which cuts the month-end workload.

The chain did not need full EDI; a shared web portal gave most of the benefit.

2. Benefits of B2B E-commerce

B2B e-commerce offers a number of benefits to businesses, including:

  • Reduced costs: B2B e-commerce can help businesses to reduce their costs by automating the procurement process and by reducing the need for paper-based documents.
  • Increased efficiency: B2B e-commerce can help businesses to increase their efficiency by streamlining the procurement process and by providing real-time access to information.
  • Improved relationships: B2B e-commerce can help businesses to improve their relationships with their suppliers and customers by providing a more efficient and transparent way of doing business.

3. The Role of EDI in B2B E-commerce

Electronic Data Interchange (EDI) lets trading partners exchange standard business documents — purchase orders, invoices, shipping notices — in a structured digital format instead of paper or PDF email. Because both systems speak the same message standard, orders can flow from a buyer’s ERP to a supplier’s system with minimal manual re-entry. EDI remains the backbone of large B2B supply chains (retail, automotive, pharma) even as newer API and marketplace platforms grow. For Nepal, EDI adoption is still limited outside major importers and multinationals, but the same idea appears in simpler form when wholesalers and retailers share Excel or portal-based orders online.

B2B E-commerce in Nepal

B2B e-commerce is still in its early stages of development in Nepal, but it is a growing market. There are a number of challenges to the growth of B2B e-commerce in Nepal, including:

  • Lack of awareness: Many businesses in Nepal are not aware of the benefits of B2B e-commerce.
  • Lack of skilled personnel: There is a lack of skilled personnel in Nepal who can implement and manage B2B e-commerce solutions.
  • Lack of a strong legal and regulatory framework: The legal and regulatory framework for e-commerce in Nepal is still developing.

Despite these challenges, there are also a number of opportunities for the growth of B2B e-commerce in Nepal. These opportunities include:

  • A large and growing number of small and medium-sized enterprises (SMEs): SMEs are the backbone of the Nepali economy, and they are increasingly looking for ways to improve their efficiency and to reach new markets.
  • A government that is supportive of e-commerce: The government of Nepal is supportive of e-commerce and is working to create a more favorable environment for its growth.
  • The increasing availability of affordable technology: The increasing availability of affordable technology, such as cloud computing and mobile devices, is making it easier for businesses in Nepal to adopt B2B e-commerce solutions.

Practical drivers in Nepal also include electronic tax invoicing and VAT reporting with the Inland Revenue Department, bank transfers and QR payments that make B2B settlement faster, and the government’s own e-procurement (e-GP) system, which has trained many suppliers to bid online. A common barrier is the habit of credit sales recorded in paper ledgers between wholesalers and retailers, which online systems must replace with trusted digital credit terms.

Summary

B2B e-commerce is the online trade of goods and services between businesses. It is larger than B2C and differs in order size, decision process, pricing, and payment terms. It grew from automated order entry and EDI into web catalogues, net marketplaces, and private industrial networks. Its main value is a cheaper, faster procurement process with fewer errors. In Nepal, B2B e-commerce is growing from simple portals and government e-procurement, held back by awareness, skills, and paper-based credit habits.

Key Takeaways

  • B2B involves larger orders, negotiated prices, credit terms, and several decision makers.
  • EDI was the first major form of B2B e-commerce and is still used by large firms.
  • The procurement process has seven steps, and B2B e-commerce cuts the cost of each.
  • A simple shared portal often delivers most of the benefit for small firms.
  • In Nepal, e-GP, digital tax invoicing, and digital payments are pushing B2B online.
