B2B, B2C AND C2C

E-COMMERCE SOFTWARE

projx digital

When you think of e-commerce, marketplaces should not be the only thing that comes to mind.

E-commerce is not a one-size-fits-all model. The infrastructure a factory needs for wholesale to its dealers cannot be the same as that of a brand selling directly to consumers, or of a venture launching a C2C marketplace. Their modeling and operational systems differ from one another. If the wrong model is chosen, the outcome is usually the same: operations scale up, but profitability does not. Instead of cumbersome models that burden the process, the usage habits of your end consumer are also taken as a basis.

At PROJX Digital, we approach this work not as “building a website,” but as commercial software architecture. With our R&D team in Şişli, we design infrastructures that automate your processes in B2B, B2C and C2C scenarios, keep integrations sustainable and are ready to grow.

WHICH E-COMMERCE MODEL
REQUIRES WHICH INFRASTRUCTURE

projx digital
B2B (BUSINESS TO BUSINESS)

When is it the right model?

If a dealer/distributor network, special price/discount structures, current-account/balance management, order limits and ERP integration are critical, the B2B model infrastructure is suitable for you.

Key needs

  • Authorized membership and role-based access (closed catalog/pricing)
  • Dealer-based pricing / discount / payment-term rules
  • Current-account balance, collection, accepting payments via virtual POS (as needed)
  • ERP/accounting integration (Logo, Mikro, SAP, etc.)
  • Setup of quote → order → shipment flows aligned with corporate scenarios

Optional smart modules

  • Stock/product demand forecasting or order recommendations (depending on data maturity)
B2C (Business to Consumer)

When is it the right model?

If your goal is fast brand-to-end-user sales, strong campaign management and high conversion, we build models for you that turn into sales within seconds.

Key needs

  • Speed and performance (especially category, product and checkout)
  • Conversion-oriented user experience (UX) and mobile-first design
  • Sales-boosting rule engines such as campaign/coupon/bundle
  • Marketing automation (cart reminders, segment-based promotions)
  • Omnichannel sales: marketplaces, Google Shopping, social commerce integrations

C2C (Consumer to Consumer) Marketplace

When is it the right model?

If your goal is a platform where users offer products/services to each other (second-hand, listings, service marketplace), we build your marketplace integrations.

Key needs

  • Membership, listing/product management and moderation flow
  • Messaging, reviews/ratings and trust mechanics
  • Commission, invoicing and rule-based revenue model
  • Marketplace model in the payment flow (scenarios such as escrow/sub-merchant payments)
  • Verification steps and tracking mechanics that reduce fraud risk

Note: The C2C payment setup is designed according to the payment institution and legal/operational requirements. We plan the architecture and integration in line with the rules of the selected payment infrastructure. Security and legal compliance are our priority.

MODEL SELECTION DECISION TREE
B2B, B2C or C2C?

Are you the seller, or are users the ones selling?

If you are the seller → B2B or B2C
If users are selling → C2C (Marketplace / Second-hand / Listings Platform)

WHAT IS THE MAIN SALES TARGET?

DEALER, DISTRIBUTOR, CORPORATE CUSTOMER?

YES: B2B
NO: B2C
DO PRICES VARY BY PERSON/COMPANY?

DISCOUNT, PAYMENT TERM, CONTRACT PRICE

YES: B2B
NO: B2C
DO ERP/ACCOUNTING
AND CURRENT-ACCOUNT SIT AT THE OPERATIONS CORE?
YES: C2C
NO: B2B/B2C
ARE COMMISSION, LISTINGS, MESSAGING, USER
VERIFICATION AND OTHER TRUST MECHANICS REQUIRED?
YES: C2C
NO: B2B/B2C

FOR MANY BRANDS THE RIGHT ANSWER IS NOT “A SINGLE MODEL,” BUT A HYBRID.
B2B + B2C (SAME CATALOG, DIFFERENT PRICE/CHANNEL RULES) OR B2C + C2C
(BRAND SALES + USER LISTINGS)

FREQUENTLY ASKED QUESTIONS

Yes, but in most B2B scenarios pricing/catalog areas are kept behind login. The authorization model is set up according to your needs. With proper categorization, the information you want reaches the right counterpart. Correct segmentation, fast access and data security are our priorities.

The marketplace payment model is planned around the capabilities of the payment institution to be integrated and the operational rules. Flows such as commission and sub-merchant payments are designed according to this model. Here, the right integration and process oversight are important.

Yes. The integration approach is determined based on the ERP’s API/service structure and data model. The goal is not just to “make it work,” but to make it work sustainably and traceably. Ensuring that your systems talk to one another and that the flow is not disrupted is also our priority. .

Yes, they can. Some brands both sell B2C and want to manage the B2B dealer channel on the same infrastructure. In this scenario, we design role-based pricing and channel rules into the architecture from the start. Your structural skeleton is defined, and the right modeling is done after that analysis.

Whichever side your business model is on, the software architecture should be built accordingly. At PROJX Digital, in B2B, B2C and C2C scenarios, we develop commercial software ecosystems whose integrations are sustainable, whose operations are manageable, and which are ready to grow. As your business evolves and shifts into other areas, we also plan the right integration and safe growth on your behalf.

With Corporate Web Design, which combines design, software, content and technical SEO, you can transform your site from merely visible into a digital hub that produces conversions.

Launching an e-commerce site is not just about opening the store door; it is about building a system where stock, order, shipping and accounting flows run flawlessly and produce conversion.
