What is C2C? Definition and scope
Core concept
C2C stands for Consumer to Consumer. In e-commerce, the C2C model means individuals or companies sell products or services to end customers through a single shared platform.
You already use C2C every day: buying clothes on Trendyol, electronics on Hepsiburada, accessories on N11, or listing on Sahibinden — all are C2C marketplace platforms.
The key point: the site owner does not hold inventory. They build and run the platform and create a safe trading environment. Sellers upload, ship, and deliver products. The owner earns commission on each sale.
C2C in one sentence
C2C = multi-vendor e-commerce. The owner provides infrastructure; sellers list products; buyers shop with confidence. Amazon, Trendyol, eBay, N11, Hepsiburada, and Alibaba all follow this model.
How the term “C2C” is used in practice
Technically C2C can mean trade only between individuals, but in the industry it usually describes hybrid marketplaces where both individuals and companies sell. Most large Turkish marketplaces work this way.
When an entrepreneur says “I want a site like Trendyol or N11,” they need C2C e-commerce software: infrastructure where every seller can open a store, upload products, and complete sales.
How does a C2C marketplace work?
Business model
There are three main parties: the platform owner, sellers (stores), and buyers. Each role is defined clearly; the system works when all three cooperate.
Platform owner
Builds and operates the site
Approves seller applications
Sets commission rules
Manages payments and shipping flows
Runs marketing
Acts as mediator between buyers and sellers
Sellers (stores)
Apply to open a store
Upload products
Manage prices and stock
Prepare and ship orders
Answer customer questions
Pay commission and package fees
Buyers
Search and compare products
Pay securely
Track shipments
Receive and confirm delivery
Request returns/exchanges when needed
Leave reviews
Order flow
On a C2C marketplace, the buyer pays into an escrow-style flow via providers such as iyzico or PayTR — not directly to the seller. The seller ships the goods. After the buyer confirms delivery (or the protection period ends), the provider deducts the platform commission and pays the seller. Both sides are protected.
Differences between C2C and B2C
Comparison
C2C and B2C are often confused. Here are the essentials.
AspectC2C (consumer to consumer)B2C (business to consumer)
Seller profileIndividual + corporateCorporate only
Barrier to entryLower; more people can sellHigher; tax registration usually required
AssortmentVery wide (new + second-hand)Usually new goods only
In reality the line blurs: many large marketplaces combine traits of both. That is why professional C2C e-commerce software should also flex to typical B2C needs.
Why build a C2C marketplace?
Why C2C?
The C2C marketplace model offers strong upside for entrepreneurs: lower inventory risk than classic retail and powerful growth potential.
No inventory risk for the owner
The platform does not stock products. Sellers handle storage and shipping. Seasonal write-offs and “unsellable stock” risk sit with sellers, not you.
Multiple revenue streams
Commission, ads, seller packages, and banner sales can run together, reducing dependence on a single source of income.
Compounding growth
Network effects: more sellers → more products → more buyers → more sellers. The loop fuels scale.
Scalability
A physical store has fixed capacity. With solid C2C e-commerce software you can grow from hundreds of SKUs to millions. Softomi has validated capacity at 7.3M products in testing.
Faster launch
With a ready marketplace platform you can go live in days instead of spending months building a basic store from scratch.
Inclusive model
More people can sell, which naturally increases assortment variety and traffic — from big brands to small merchants.
Four core revenue models
Revenue channels
A C2C marketplace can combine all of the following when planned well.
1
Commission
Primary revenue. A percentage is taken on each sale — often around 15–20% in the industry. Rates can be global, per category, or per seller. Usually calculated on product price excluding shipping and taxes.
2
Sponsored placement packages
Sellers pay for better positions in search and categories. Click-based packages scale with competition (e.g. 100 clicks for X, 200 clicks for Y).
3
Seller subscription packages
Time- or volume-based listing plans (e.g. 1,000 products for 3 months). Predictable recurring revenue.
4
Slider & banner sales
Homepage and category hero slots are rented by day or week. High-traffic sites monetize these placements strongly.
Pioneer since 1998; evolved from electronics focus into a full marketplace.
N11
Major Turkish marketplace since 2013 with broad categories.
eBay
Early global marketplace (1995); auctions + fixed price; 190 countries.
AliExpress
Alibaba Group; Chinese sellers, global buyers; wide assortment.
Sahibinden
Turkey’s largest classifieds — vehicles, real estate, second-hand goods.
Yemeksepeti
Food-delivery marketplace connecting restaurants and customers.
C2C is not limited to physical goods: food, travel, autos, and real estate all fit the model — a key reason entrepreneurs find it attractive.
What the marketplace owner must do
Operations
In C2C, the owner has three critical jobs — each essential to long-term success.
01
Attract the right suppliers
Success starts with trustworthy sellers and good products. Large brands may hesitate at launch when traffic is still low.
Softomi marketplace software helps: sellers can connect existing Trendyol/N11 stores via API and import products in one step, or use bulk XML/Excel tools.
Lower commissions and free starter packages early on are proven ways to onboard sellers.
02
Keep sales processes disciplined
You must manage relationships between stores and customers: shipping, correct fulfillment, returns, and complaints.
Secure payment / escrow-style flows hold buyer funds until delivery is confirmed. With Softomi’s iyzico integration, GeT-style confirmation, commission splits, and payouts can be automated.
03
Sustainable growth and marketing
Growth must stay healthy: too fast without staff and processes creates support debt.
Start with paid channels (Google, Meta, Instagram), then layer SEO. Avoid overly aggressive SEO in the first months of a new domain; balance paid and organic over time.
Supplier management & store lifecycle
Operations
Suppliers are the lifeblood of any C2C platform.
Store application
A professional onboarding flow builds trust — documents, contract acceptance, and payout details in one journey.
Approval & activation
You review applications, verify documents, and activate compliant stores.
Product upload
Single items, bulk files, or API imports (e.g. from Trendyol/N11). Ready XML templates speed this up.
Moderation
Listings pass review; prohibited or low-quality items are blocked to protect brand trust.
Sales & payment flow
Transaction flow
Payments are structured to protect buyers and sellers, centered on payment provider integration.
1
Order & payment
Buyer pays by card or transfer; funds go to iyzico/PayTR, not straight to the seller.
2
Seller notification
Seller sees the order in the panel and receives email/SMS alerts.
3
Packing & shipping
Seller ships and enters tracking; buyer is notified.
4
Delivery & confirmation
Buyer confirms receipt or the protection window auto-closes after 14 days.
5
Commission & payout
The provider deducts commission and transfers the remainder to the seller; you keep commission income.
Softomi automates this end-to-end — no manual spreadsheets required.

Early on you face the chicken-and-egg problem: no sellers without buyers, no buyers without listings. Strategy breaks the loop.
Start with lower commission
Offer 5–10% early, then move toward industry norms as volume grows.
Free starter plans
3–6 months of free listing tiers removes friction for first-wave sellers.
Faster payouts
Paying sellers sooner than competitors improves cash flow for them — a strong differentiator.
Targeted ads
Use Google and social ads for the right niches; allocate ~10–15% of budget to remarketing.
Cost buckets for a C2C site
Cost overview
Plan for four major cost areas when launching and running a C2C marketplace.
1. Software
C2C e-commerce software is far deeper than a simple store: seller panels, commissions, ads, packages, and more. Custom builds can reach tens of millions of TRY; ready solutions reduce upfront cost.
2. People
You typically need at least one technical/ops person at the start; later add category, marketing, and support roles.
3. Marketing
Budget for ads and SEO continuously; focus on efficient targeting, not only spend volume.
4. Company & office
Entity setup, accounting retainer, and optional small office — remote-first is viable for this model.
It is the professional stack to launch, operate, and scale a multi-vendor marketplace — far beyond a single-store cart because owners, sellers, and buyers all need dedicated experiences.
Must-have building blocks
Admin panel
Seller onboarding & approvals
Product moderation
Category-based commissions
Reporting & analytics
Search keyword reports
Bulk actions
Seller panel
Easy product creation
Bulk upload (XML, Excel)
Trendyol & N11 API bridges
Buying ad & listing packages
Order & shipping tools
Revenue reports
Shopping experience
Advanced search & filters
Single catalog, multiple seller offers
Auction module
Offer / bidding flows
Responsive design
Secure checkout (iyzico, PayTR)
Choose software built by teams with real marketplace experience — generic web agencies often miss operational nuances.
