In B2С ecommerce, when you visit an online store, you can see prices that are the same for all consumers. Yes, there may be targeted price options for people from certain regions, but these are special cases and not the general rule. Transactions in B2C are carried out very quickly - you enter the credit card number, click the “buy” button, and that’s all; now wait for your purchase.
In the B2B segment, everything is much more complicated. Only small purchases are allowed to be paid with corporate credit cards, so generally the payment takes longer and is more complicated. The buyer sends the invoice to the seller, where the legal staff checks this document, then finance puts the invoice in the payment queue, and only then money for the purchase comes to the bank account of your company. This is important to know for small companies, because if you sell something to a large corporation, there are often special conditions of delayed payment of 30 or even 60 days. Sure, you will receive the money, but not so quickly. This is the great difference between B2C and B2B transactions.
