E-commerce
Definition
E-commerce
E-commerce is the internet-mediated buying and selling of goods, services, and the payment data that moves with them. It splits into six models: B2B, B2C, C2C, C2B, B2A, and C2A. If a browser, app, or API touches the sale, it counts.
Global retail e-commerce reached roughly $6.3 trillion in 2024, per eMarketer. The field spans a Manila BPO ordering software licences and a Bangkok shopper subscribing to a streaming service. Both sit inside the same definition.
The mechanics stay consistent whatever the model. A buyer’s device pings a merchant’s server, a payment gateway clears the funds, and a fulfilment layer ships the good or unlocks the service. What varies is who buys from whom — and why.
Scale is what makes the term matter to operators. A storefront that ships 500 orders a day needs different support cover, different fraud checks, and different returns handling than one shipping 50,000. Volume drives the operating model.
Key takeaways
- E-commerce is any internet-mediated sale plus the payment and data exchange wrapped around it.
- Six models split the field: B2B, B2C, C2C, C2B, B2A, and C2A.
- B2B orders carry higher values and slower sales cycles than B2C sales do.
- E-commerce reached 16.4% of total U.S. retail sales in the fourth quarter of 2024.
- Outsourced support, moderation, and fulfilment teams sit behind most large storefronts.
How it works
An e-commerce transaction runs a fixed loop. A buyer’s browser or app sends an order to the merchant’s server, a payment gateway clears the funds, and a fulfilment layer ships the good or grants digital access.
Each step generates data the merchant reuses for retention, targeting, and forecasting. The variable is the buyer-seller pairing — read the table below as a map of intent, not just of parties.
| Model | Who buys from whom | Typical example |
|---|---|---|
| B2B | Business ↔ business | Salesforce selling CRM seats to a Manila BPO |
| B2C | Business → consumer | Lazada shipping a phone to a Bangkok shopper |
| C2C | Consumer ↔ consumer | An eBay auction between two collectors |
| C2B | Consumer → business | A freelancer licensing stock photos on Shutterstock |
| B2A | Business → government | An IT firm invoicing a state agency for cloud hosting |
| C2A | Consumer → government | Filing taxes online via the Philippines BIR eFPS portal |
B2B deals typically run longer sales cycles, higher order values, and more repeat orders than B2C. C2B and B2A are the fastest-growing segments as reverse-auction platforms and e-government portals mature, per UNCTAD’s 2024 digital economy tracking.
Three infrastructure layers do the heavy lifting behind the scenes: a catalogue and cart system, a payment gateway such as Stripe, PayPal, GCash, or Adyen, and a fulfilment stack mapping SKUs to warehouses, couriers, and customs paperwork.
Cross-border sales add a fourth layer: tax, duty, and currency handling. A Philippine seller shipping to Australia has to price in GST, customs clearance, and a peso-to-dollar conversion before the margin is real.
Scale matters to the model choice. E-commerce accounted for 16.4% of total U.S. retail sales in the fourth quarter of 2024, per the U.S. Census Bureau, which still leaves most spending offline.
When any layer stalls, orders stop within minutes. Consumer behaviour drives B2C, so merchants watch cart-abandonment rates, post-purchase CSAT scores, and repeat-order lift to judge whether a channel deserves more budget.
Examples
Amazon, Shopify, Alibaba, and Shopee anchor the four e-commerce archetypes most Southeast Asian buyers meet daily. Amazon runs pure B2C, Shopify sells the underlying stack, Alibaba dominates B2B, and Shopee brings social commerce to ASEAN shoppers.
Amazon (B2C at scale): Net sales cleared $638 billion in 2024, per the company’s Q4 earnings. Its Manila and Cebu customer-service teams answer post-purchase queries in English, Spanish, and Japanese, most through offshore staff-leasing partners.
Shopify (B2C infrastructure): The platform powered more than 4.6 million active storefronts by the end of 2024, per BuiltWith. Shopify Plus merchants routinely offshore chat and refund workflows to KPO partners in the Philippines and India.
Alibaba (B2B pioneer): Singles’ Day 2024 gross merchandise value cleared an estimated $84 billion across Tmall and Taobao, per Bain & Company. Alibaba still hosts the world’s largest cross-border B2B marketplace.
Shopee (regional B2C): Southeast Asia’s most-visited e-commerce app in 2024, per Momentum Works, with warehousing and support operations spread across Singapore, Manila, and Jakarta.
Payment habits split the region as sharply as the platforms do. Cash on delivery still clears a large share of Southeast Asian orders, while GCash, Maya, and card rails carry the rest, so support teams field payment questions constantly.
Behind each storefront sits an operations layer of offshored teams: customer support, dispute resolution, listing moderation, and reverse-logistics coordination, usually run out of Manila, Cebu, or Bengaluru.
That layer is why e-commerce headcount rarely sits where the storefront does — a Sydney merchant can run a 24-hour support desk from Cebu, then hand fraud review to a Bengaluru team on the next shift.

FAQ
What are the main types of e-commerce?
Six models cover almost every online sale: B2B, B2C, C2C, C2B, B2A, and C2A. Business-to-consumer is the most visible, business-to-business carries the largest order values, and C2A covers services like online tax filing.
Is e-commerce the same as e-business?
No. E-commerce covers the sale, the payment, and the data flow around a transaction. E-business is broader — it covers every digital process a company runs, from HR onboarding to supply-chain analytics.
How big is the global e-commerce market?
Global retail e-commerce reached about $6.3 trillion in 2024, per eMarketer, with forecasts topping $8 trillion by 2027. In the United States, e-commerce made up 16.4% of retail sales in the fourth quarter of 2024.
What does a BPO team do for an e-commerce store?
Offshore teams handle chat and email support, order-status queries, refunds and disputes, content moderation, and product-listing enrichment. Larger merchants also outsource fraud review and returns processing to specialists in the Philippines and India.
How does e-commerce differ from traditional retail?
E-commerce runs on catalogue data, payment gateways, and shipping partners rather than physical footfall, so fixed costs skew toward technology and logistics.
