B2C means business-to-consumer: a business sells goods or services to an individual consumer. B2C marketing begins with the buying situation, not the assumption that consumer purchases are cheap or immediate. Identify who buys and uses the offer, provide the information they need, and compare results using a consistent customer cohort and cost scope.

What is B2C? B2B, C2C, and DTC explained

B2B describes business-to-business transactions, while C2C describes transactions between consumers. Direct-to-consumer, or DTC, is a form of B2C in which a manufacturer or brand sells directly to consumers. Shopify’s B2C guide distinguishes these relationships.

C2C; separate from the platform’s service

Classify the transaction, not just the company or website. A manufacturer can make both wholesale and direct sales. A marketplace can involve a seller’s consumer transaction and a separate service supplied to the seller. State which relationship your plan and revenue figures describe before comparing results.

Identify the buyer, user, and other decision-makers

The person paying may be different from the person using the product. Gifts, family purchases, and services for children can involve several people’s preferences and concerns. Treating B2C as a decision driven only by one person’s emotions can leave important questions unanswered.

Identify the buyer, user, people helping compare options, and person managing payment. This does not mean advertising to each person separately. It helps determine whose question needs an answer and where that information belongs before or after purchase.

  • Can the buyer explain the relevant conditions to the user?
  • Can the user understand how the offer fits their situation?
  • Do other decision-makers have clear total costs and limitations?
  • Are payment, renewal, and cancellation conditions understandable?

Use interviews and inquiry records to test your assumptions. Demographics alone do not establish why someone buys. Ask what people compared, what concerned them, and what information helped them decide.

Compare routine purchases, high-value decisions, and subscriptions

Consumer purchases range from routine essentials to expensive, long-term decisions such as homes and vehicles. The following fictional planning examples compare decision burden rather than imposing one universal B2C journey. Adapt them to price, risk, participants, and commitment.

Situation

People involved

Likely question

Information or contact needed

Outcome to verify

Routine consumable

Buyer, and sometimes a user

Price, availability, delivery

Product information and purchase or store guidance

Accepted orders, stockouts, cancellations

High-value family purchase

Buyer and family members

Total cost, comparison, long-term conditions

Comparison material, consultation, quotation

Suitable consultations and confirmed sales

Ongoing service

Account holder and users

Continuing value, billing, cancellation

Onboarding and relevant ongoing guidance

Adoption, renewal, cancellation, contribution

A short explanation may be enough for one decision; another may require detailed comparison and consultation. Trust and emotion also affect business purchases. Instead of dividing B2C and B2B into emotional versus rational decisions, identify the concrete uncertainty people need to resolve.

Choose channels for the customer’s stage

Choose activities for the information or experience missing between discovery, comparison, purchase, and continued use. The AMA’s marketing and advertising explanation helps distinguish broader marketing work from paid promotion. The value promised by an ad needs to connect with product information and the experience after purchase.

Stage

Customer’s question

Possible activity

Separate activity from outcome

Discovery

Is this relevant to me?

Articles, demonstrations, or ads explaining a use case

Views versus movement to further information

Comparison

Does it meet my conditions?

Specifications, total cost, limitations, comparison

Requests versus suitable consultations

Purchase

Can I complete this confidently?

Stock, delivery, payment, and form guidance

Interactions versus accepted orders

Continued use

Am I receiving value?

Onboarding and relevant ongoing communication

Usage versus verified retention or repurchase

You do not need to invest in every stage at once. Prioritize using customer questions and missed opportunities. Membership or social media programs do not automatically increase repeat purchases or profit. Evaluate their cost and the customer population they affect.

Read revenue, CAC, retention, and contribution consistently

Before reading CAC or repeat purchase rates, fix the customer cohort and observation window. Mixing newly acquired customers with people already observed for 90 days changes how much opportunity each person had to buy again. Verify people using appropriate customer records rather than treating orders or analytics events as customer identities.

Metric

Definition to record

Keep separate from

CAC

Cohort acquisition cost / new customers in that cohort

A partial-media CPA or existing customers

Repeat customer rate

Customers who repurchased in the window / eligible customers

Repeat order count

Revenue per acquired customer

Adjusted window revenue / acquired customers

Estimated lifetime revenue

Observed contribution

Revenue less the specified variable and other included costs

Net profit after fixed costs

Document whether acquisition cost includes media, fees, production, and other relevant costs. Align tax, returns, and cancellations when calculating revenue. Specify which product, delivery, and related costs are included. Revenue-based lifetime value, contribution-based lifetime value, observed results, and future estimates answer different questions.

A worked 90-day customer cohort and next steps

This hypothetical cohort contains 100 new customers, each correctly identified and observed for 90 days from the first purchase. Assume one first order per person and 140 orders after return and cancellation adjustments. The 40 repeat orders were placed by 30 customers. Net revenue excluding tax is JPY700,000, product and delivery-related variable costs are JPY420,000, and cohort acquisition cost is JPY150,000.

JPY2,800

Observed contribution per customer after acquisition

(JPY700,000 − JPY420,000 − JPY150,000) / 100

JPY1,300

The cohort’s total contribution after acquisition is JPY130,000. Its 140 orders are not 140 people, and 40 repeat orders are not 40 repeat customers. Fixed costs are excluded, so this is not net profit. It is a 90-day observation, not lifetime value.

Compare another cohort only after aligning these definitions and observation time. Investigate acquisition cost, repeat buying, returns, and variable costs separately. A higher repeat customer rate can coincide with lower contribution if discounts or delivery costs increase. Use the transaction and journey tables to choose the right information, then use the cohort worksheet to identify the next stage to improve.
