B2B means you sell to businesses, B2C means you sell to private consumers. The difference is not the product but the buying process: B2B deals involve several decision-makers, longer sales cycles, invoices and contracts, while B2C purchases are usually made by one person in minutes and paid immediately. The same coffee machine can be sold both ways.
The practical difference shows up in your numbers. To reach 20,000 euros of monthly revenue you need either 40 business customers paying 500 euros a month, or 4,000 consumers paying 5 euros a month. Both give the same total and almost nothing else in common. With 40 customers you can call each one by name, and losing three of them cuts revenue by 7.5 percent. With 4,000 consumers, losing three changes nothing, but you need support that works without conversations.
Acquisition budgets follow from that. A business customer worth 6,000 euros a year can justify 1,500 euros of sales effort: calls, a demo, a trip. A consumer worth 60 euros a year cannot justify more than about 15 to 20 euros, so the whole process has to run through advertising and self-service.
Founders often assume B2B is easier because there are fewer people to convince. In fact a B2B deal often takes three to nine months and passes a user, a budget holder and sometimes a legal or IT check. You need enough cash to survive that gap. The second common error is forgetting who decides. In B2C the user and the payer are usually the same person. In B2B the person who uses your software often has no budget, so your message needs a version for the user and a version for the person who signs.
Price display differs too. Consumer prices are quoted including VAT, because that is what the customer pays. Business prices are quoted net, because the buyer reclaims the VAT. Getting this backwards makes your offer look more expensive than it is, by the full VAT rate.
