1.3 Types of E-Commerce
E-commerce is classified by the type of parties involved in the transaction. The IPU syllabus mentions five core types — B2B, B2C, C2C, M-commerce, Social Commerce. The complete taxonomy adds B2G, C2B, and G2C.

1. B2B — Business to Business
Definition: electronic transactions between two businesses — manufacturer-to-distributor, wholesaler-to-retailer, business-to-supplier.
Characteristics
- High transaction value (₹ lakhs to crores per order)
- Long sales cycles (procurement processes, RFPs, negotiations)
- Repeat orders (regular suppliers)
- Custom pricing (tier-based, contract-based)
- EDI / API integration between buyer and seller systems
Examples
- IndiaMART, TradeIndia, Alibaba — B2B marketplaces
- Udaan — B2B for kirana retailers
- Walmart Business — supply chain to small businesses
- Amazon Business — B2B procurement
- Cisco's online order system (~85% of orders are B2B online)
Sub-types
- Supplier-oriented (sell-side) — supplier hosts the marketplace (e.g., Cisco)
- Buyer-oriented (buy-side) — large buyer hosts (e.g., Walmart purchasing portal)
- Intermediary marketplace — third party hosts (e.g., IndiaMART)
Scale fact: B2B e-commerce is 3–6× larger than B2C globally — but less visible because transactions are not consumer-facing.

2. B2C — Business to Consumer
Definition: sales from businesses to individual consumers — the most visible form of e-commerce.
Characteristics
- Low ticket size (₹100 to ₹1 lakh typically)
- Short sales cycle (browse-to-buy in minutes)
- Massive volume (millions of transactions/day for large platforms)
- Mass-market pricing (catalog pricing, with sales / discounts)
- Marketing-heavy (ads, SEO, influencers)
Examples
- Amazon, Flipkart, Myntra, Nykaa, Ajio — retail
- Zomato, Swiggy — food
- Blinkit, Zepto — quick commerce
- MakeMyTrip, IRCTC — travel
- Netflix, Hotstar — streaming services
- Practo, PharmEasy — healthcare
- Byju's, Unacademy — edutech
---
3. C2C — Consumer to Consumer
Definition: consumers sell directly to other consumers, usually via an intermediary platform.
Characteristics
- Low ticket size (mostly < ₹1 lakh)
- Used / second-hand goods (most C2C is resale)
- Platform takes commission (~5–15%)
- Trust mechanisms (ratings, escrow, dispute resolution)
Examples
- OLX, Quikr — classifieds, used goods
- eBay, Etsy — auction / craft
- CarTrade, Cars24 — used cars
- Spinny — used cars (more curated)
- Mercari, Vinted (global) — used clothes
- Airbnb — peer-to-peer accommodation (technically C2C with platform)
Trust as a service: C2C platforms succeed not by handling transactions, but by establishing trust between strangers. Ratings, escrow, return guarantees are core platform value.
---
4. B2G — Business to Government
Definition: businesses sell to government agencies — usually via tender / procurement portals.
Examples
- GeM (Government e-Marketplace, India) — ₹5 lakh crore+ procurement
- CPPP (Central Public Procurement Portal)
- e-Tendering portals by Railways, DRDO, ISRO, PSUs
Characteristics
- Highly regulated (tender processes, bid security, performance bonds)
- Multi-stage approvals
- Long fulfilment cycles
- E-invoicing under GST mandatory
---
5. C2B — Consumer to Business
Definition: individuals sell goods or services to businesses — inverse of traditional B2C.
Examples
- Stock photo sites (Shutterstock, Adobe Stock — photographers sell to businesses)
- Freelancer platforms (Fiverr, Upwork, Toptal — individuals sell services)
- Influencer marketing platforms (BuzzFeed influencers selling reach)
- Crowdsourcing (Threadless designs by users, used by the brand)
- Affiliate marketing (consumer-as-promoter)
---
6. G2C — Government to Consumer
Definition: governments provide services or transact with citizens electronically.
Examples
- IRCTC — rail booking
- Passport Seva, Aadhaar enrolment, e-Visa
- Income-Tax e-filing
- DigiLocker, e-Hospital, mGov
- BBPS (Bharat Bill Payment System) — utilities
- Bhoomi (Karnataka), Mee Seva (AP) — land/services
- e-Hospital, e-Mandi, ONORC (ration cards)
---
7. M-Commerce — Mobile Commerce
Definition: e-commerce conducted via mobile devices (smartphones, tablets, wearables) over wireless networks.
M-commerce is not a separate transaction type (it overlaps B2C, B2B, C2C) — it is a delivery channel distinguished by device and context.
Characteristics
- Location-aware (GPS-based recommendations, Uber, Swiggy)
- Push-notification driven (offers, abandoned-cart reminders)
- Mobile-first UX (vertical scroll, swipe, thumb-friendly)
- Touch-based payments (UPI, biometric, NFC)
- App + browser channels
Examples
- Almost all modern e-commerce is m-commerce-dominant — Flipkart reports ~85% of orders from mobile.
- WhatsApp Business — direct order placement
- UPI — entirely mobile
- Quick commerce (Blinkit, Zepto) — exclusively mobile
M-commerce categories
| Category | Example |
|---|---|
| Mobile shopping | Amazon app |
| Mobile banking | YONO SBI, HDFC PayZapp |
| Mobile payment | UPI apps, Paytm, PhonePe, Google Pay |
| Mobile ticketing | IRCTC Rail Connect, BookMyShow |
| Location services | Uber, Ola, Google Maps shopping |
| Mobile marketing | SMS campaigns, push notifications |
| Mobile entertainment | Streaming, gaming apps |
---
8. Social Commerce
Definition: commerce conducted through social-media platforms — purchase decisions, discovery, and even transactions happen inside social media.
Sub-types
| Sub-type | Description | Examples |
|---|---|---|
| Social discovery | Discover products via social posts/reviews | Instagram shopping, Pinterest pins |
| Reseller / referral commerce | Consumers resell to their network | Meesho, GlowRoad, DealShare |
| Live commerce | Live-streamed product demos with embedded checkout | China's Taobao Live ($150B+ GMV); India: Bulbul, Simsim |
| Group buying | Collective discount when enough buyers join | Pinduoduo (China); DealShare; CityMall |
| Influencer commerce | Influencer drives purchase via affiliate link | Instagram + Linktree, YouTube reviews |
Why social commerce works
- Trust transfer — friend's recommendation > ad
- Community discovery — Pinterest as visual search
- Frictionless checkout — Instagram Checkout, WhatsApp pay
- Social proof — reviews, likes, shares
India social commerce GMV: $7–8 billion (2023), projected $70+ billion by 2030. Meesho alone has 150 million+ users.

Key Terms — Lesson 1.3
The eight types above are themselves the lesson's primary vocabulary. The terms below are the supporting concepts that recur across types — they are what an examiner expects you to define if asked to "discuss" or "compare" types in a 12-mark question.
B2B (Business-to-Business) — Commercial transactions where both parties are organisations: manufacturer to distributor, wholesaler to retailer, parts supplier to OEM. B2B is characterised by high ticket size, long sales cycles, repeat orders under contract, and system-to-system integration via EDI or modern APIs. Globally, B2B e-commerce GMV is roughly 5–6× larger than B2C, even though B2B is much less visible to ordinary consumers.
B2C (Business-to-Consumer) — The most visible form of e-commerce: a registered business sells to individual end-consumers via a website or app. Tickets are low to medium (₹100–₹1 lakh), sales cycles are short (browse-to-buy in minutes), and marketing is acquisition-heavy. Amazon, Flipkart, Nykaa, Zomato, Netflix are all primarily B2C.
C2C (Consumer-to-Consumer) — Individuals selling directly to other individuals, almost always through an intermediary platform that handles discovery, payment, and dispute resolution. The platform's primary value is trust between strangers — ratings, escrow, return guarantees, identity verification. OLX, Quikr, eBay (auction), and Mercari are pure C2C; Airbnb is C2C with strong platform support.
B2G (Business-to-Government) — Businesses sell to government agencies through structured procurement processes — tenders, RFQs, performance bonds, GST e-invoicing. In India, the Government e-Marketplace (GeM) has crossed ₹5 lakh crore in cumulative procurement since 2016 and is now mandatory for most central-government purchases. B2G demands rigorous compliance, audit trails, and long fulfilment cycles.
C2B (Consumer-to-Business) — The inverse of B2C: an individual sells goods or services to a business. Stock-photo sites (a photographer licenses an image to a brand), freelance marketplaces (a designer delivers work to a startup via Upwork), and influencer-marketing platforms (a creator sells audience reach to an advertiser) are the canonical examples. Affiliate marketing — where a consumer promotes a brand's products on their channel for a commission — also fits C2B.
G2C (Government-to-Citizen / Government-to-Consumer) — Government delivery of services to citizens through digital channels: IRCTC for rail tickets, Passport Seva, Income-Tax e-filing, DigiLocker, Bharat Bill Payment System (BBPS), and Aadhaar enrolment. G2C is not primarily commercial, but its scale (~1 billion users in India alone) and its rails (UPI, Aadhaar, DigiLocker) underpin much of the country's wider e-commerce economy.
G2B (Government-to-Business) — The procurement and regulatory counterpart of G2C: government issues tenders, releases datasets, runs licensing portals, files notices. In India the Central Public Procurement Portal (CPPP) and Ministry-of-Corporate-Affairs MCA21 portal are the main G2B touchpoints.
M-Commerce (Mobile Commerce) — Any e-commerce conducted via mobile devices (smartphones, tablets, wearables) over wireless networks. M-commerce is not a separate transaction type — it cuts across B2B, B2C, and C2C — but it is distinguished by its context-awareness: location-based offers, push notifications, touch-optimised UI, and biometric or UPI-style instant payments. In India, m-commerce dominates: Flipkart reports ~85% of orders from mobile, Meesho is almost 100% mobile.
Social Commerce — Commerce where discovery, trust, and increasingly checkout happen inside social networks rather than on search engines or merchant websites. Sub-types include social discovery (Instagram shopping, Pinterest), reseller / referral commerce (Meesho's WhatsApp-led model), live commerce (real-time streamed sales — huge in China, growing fast in India via Bulbul and Simsim), group buying (Pinduoduo, DealShare), and influencer commerce (creator drives sales via affiliate links).
Marketplace Model vs Inventory Model — Two opposing platform models. A marketplace (Amazon, Flipkart, Meesho, eBay) lists third-party sellers and earns a commission on each sale — it does not own the inventory and bears no inventory risk. An inventory-model retailer (Myntra in its early years, BigBasket, Nykaa) buys stock and resells from its own warehouses, earning the full retail margin but carrying inventory risk. Indian FDI rules until 2018 prohibited foreign companies from running inventory-model B2C, which is why most foreign-funded platforms are marketplaces.
Escrow — A neutral holding mechanism in which the buyer's payment is held by the platform (or a bank) until the seller completes the agreed delivery. Escrow is the trust mechanism that lets C2C and marketplace platforms work — without it, a stranger paying another stranger would have no recourse. Stripe, Razorpay, and the platforms themselves run escrow accounts.
Tender / Request for Proposal (RFP) / Request for Quotation (RFQ) — The procurement vocabulary used in B2B and B2G. An RFI (Request for Information) precedes the buyer's decision; an RFP invites detailed proposals on how the work will be done; an RFQ asks for specific price quotes against a defined scope; the tender is the formal published call. GeM and CPPP automate these workflows for Indian government purchases.
Live Commerce — Real-time, video-streamed product sales where viewers can ask questions and check out without leaving the stream. China's Taobao Live crossed US$ 150 billion GMV in a year by 2023. Indian live-commerce startups (Bulbul, Simsim, Roposo Clout) are smaller but growing fast in fashion, beauty, and gadgets.
Average Order Value (AOV) — The mean revenue per completed order: total revenue ÷ number of orders. AOV varies enormously by category — quick-commerce ~₹200, fashion ~₹1,500, electronics ~₹5,000, B2B ~₹50,000+ — and is a primary lever for unit economics. Common strategies to lift AOV: bundle discounts, free shipping above a threshold, "frequently bought together" upsells.

Study deep
- Type is determined by buyer-seller, not by product or channel. A laptop sold on Amazon = B2C. The same laptop bought by a company on Amazon Business = B2B. The product is identical; the relationship is different.
- B2B dwarfs B2C in value. Globally B2B is ~5× B2C in transaction value. B2C is more visible (consumer ads, news coverage) but B2B is the bulk of e-commerce volume.
- Hybrid types are common. Amazon is B2C (selling to consumers) AND B2B (Amazon Business) AND C2C (third-party seller marketplace) AND C2B (some affiliates) — all simultaneously. Modern platforms blur the lines.
- India leapfrogged in social commerce. Lower internet costs + WhatsApp dominance + Hindi/regional language UX made social commerce work better in tier-2/3 India than in the West. Meesho's success has no clear US/EU parallel.
- Type drives technology choices. B2B needs EDI/API + complex pricing tiers + RFQ workflows. B2C needs catalog + cart + simple checkout + mass marketing. C2C needs identity verification + escrow + dispute resolution. Each type has its own tech stack.
PYQ pattern (almost guaranteed): "Explain different types of e-commerce with examples." — Define 5–6 core types, table them with example + ticket size + volume, conclude with hybrid platforms (Amazon).
PYQ pattern: "What is m-commerce? Differentiate it from e-commerce." — M-commerce is a subset of e-commerce (mobile-device-based); list 4 distinguishing features (location, push, touch, mobile-first UX); India-specific scale (Flipkart 85% mobile).
