What is B2B?
B2B (Business to Business) is a business model that refers to commercial activities between businesses; the buyer is not an individual consumer, but a business placing an order on its behalf. Most production and supply chains interact with the B2B business model at some point — encompassing a wide range from raw material sourcing to wholesaler-retailer relationships.
-
Raw material supply: manufacturing companies procuring the necessary raw materials (e.g., petrochemical sector, B2B supply platforms).
-
Functional collaborations: operational service agreements, such as catering, where one company obtains services from another.
-
Wholesaler-retailer relationship: manufacturers making bulk sales agreements with retail companies such as chain supermarkets.
What are the differences between B2B, B2C, and C2C?

Model |
Among whom? / Example |
|
B2B (Business to Business) |
One business sells to another; this involves bulk ordering and a multi-step decision-making process (e.g., raw material procurement, wholesaler-retailer agreements). |
|
B2C (Business-to-Consumer) |
A business sells directly to the individual end consumer; the decision-making process is faster (examples: virtual marketplaces, branded e-commerce sites). |
|
C2C (Consumer-to-Consumer) |
A consumer sells an item they previously purchased to another consumer; there is no obligation to issue an invoice (e.g., selling second-hand goods). |

What is B2C? What are its advantages?
B2C (Business to Customer) refers to direct sales from the manufacturer to the end consumer; it is conducted through virtual marketplaces (such as n11, Hepsiburada, Trendyol) or the business's own e-commerce website/app.
-
Global sales potential: a wide customer base can be reached without geographical boundaries.
-
Reduced physical store expenses: costs such as rent and staff decrease in an online model.
-
Customer analysis and data-driven decision-making: purchasing behavior data feeds campaign and inventory decisions.
What is C2C?
C2C (Consumer to Consumer) is when a consumer sells a new or used product they have previously purchased to another consumer. There is no obligation to issue invoices for these types of sales; however, platform-based commissions or listing fees may apply.
An Example from a Sector: A Business That Is Thought to Be B2C Is Actually B2B
A stationery manufacturer, who defined himself as a 'B2C' business because he sold his products through his own e-commerce site, realized that the majority of his orders actually came from office supply wholesalers and corporate clients. This showed that the business should be managed not with a B2C e-commerce site structure, but with a B2B infrastructure requiring bulk ordering and distributor-specific pricing.
“Our site looked like B2C, but most of the orders were from a single customer buying 500 units; when we realized this, we switched to a B2B infrastructure,” says the company's sales manager.
