What Is a Checkout Flow? And the B2B Equivalent

A checkout flow is the series of steps a visitor goes through to complete an online purchase: from the shopping cart to their details, the shipping choice, the payment and the confirmation. It is the final and most critical phase of a purchase, where money and attention sit closest together. Every extra step or ambiguity costs revenue here. This is first and foremost an e-commerce concept, so in this article we explain what a checkout process is and what the B2B equivalent looks like if you do not have a webshop.

What exactly is a checkout flow?

The checkout flow starts the moment a visitor decides to buy and ends with the confirmation of the order. A typical flow consists of a few clear steps:

• The shopping cart: an overview of what the customer is buying, with price and quantity.
• Customer details: name, address and contact details, whether or not through an account.
• Shipping or delivery options: the choice of how and when delivery happens.
• Payment: the payment method and the transaction itself.
• Confirmation: the confirmation page and usually an email.

The less friction in those steps, the more people complete their purchase. Every doubt, every extra field and every unexpected cost is a reason to drop off.

Why do so many people abandon the checkout?

Because checkout is the point where the visitor becomes most critical. A review of dozens of studies by the Baymard Institute shows that on average nearly 70% of online shopping carts are abandoned. That is not a detail, that is the bulk of your revenue walking away at the last moment.

The causes are strikingly consistent:

• Unexpected costs that only appear late (shipping, taxes, surcharges).
• A mandatory account you have to create before you are allowed to pay.
• A flow that is too long or too complex, with too many steps and fields.
• Doubts about security or a lack of trust signals.
• Too few payment methods, or no payment method the customer trusts.

The lesson is always the same: remove friction. Ask only for what you genuinely need, be honest up front about the total price, and make every step crystal clear. That is exactly the same logic as removing friction in the final conversion phase.

What is the B2B equivalent of a checkout flow?

Here is the honest nuance: as a B2B company without a webshop, you usually do not have a checkout flow. Nobody pays for a service with a complex scope by simply tapping a credit card. You are selling a decision that involves multiple stakeholders and a long sales cycle, not an impulse purchase.

The B2B equivalent is your conversion flow towards a lead: the path from visitor to demo request, quote request or contact form. And exactly the same laws apply there as in a webshop checkout. A form with too many fields is your version of a checkout that is too long. An unclear next step is your version of unexpected costs. How to tackle that is covered in conversion optimization for forms.

So do not think in terms of “paying”, but in terms of “making the threshold to get in touch as low as possible”. Every field you cut and every ambiguity you remove lifts your conversion rate the same way a streamlined checkout does for a webshop.

When does B2B actually have a real checkout?

There is one clear exception: self-serve SaaS. With product-led growth, a customer can sign up, pick a subscription and pay online without any involvement from sales. Then you do have a real checkout flow, and all the e-commerce rules apply in full.

For that model, the payment step is a crucial conversion point. An upgrade or payment flow that is too complex costs you paying users directly. You can read more about that model in our explainer on product-led growth. Here too, the core is not cosmetics but removing friction: fewer steps, clear pricing and a payment experience that inspires trust.

How do you optimize a checkout or conversion flow?

Whether you have a real checkout or a B2B form flow, the approach is the same and it starts with research, not with an opinion:

1. Measure where people drop off. Which step loses the most visitors? That is your biggest lever.
2. Cut everything that is not essential. Every field and every step you can leave out increases the chance of completion.
3. Be clear up front. Show the total price, the next step and what happens after the click.
4. Build trust at the decisive moment. Payment and security signals in a checkout, proof and clarity in a B2B form.
5. Test with evidence. If you have enough traffic, test; if you do not, improve on the basis of research. See our broader approach in conversion optimization.

Frequently asked questions about the checkout flow

What is the difference between a shopping cart and a checkout flow? The shopping cart is the overview of what the customer wants to buy. The checkout flow is the whole process that follows: entering details, choosing delivery options, paying and confirming. The shopping cart is therefore the start of the checkout flow.

What is a good abandonment rate in the checkout? On average, nearly 70% of shopping carts are abandoned, so anything structurally below that figure is already better than average. The exact percentage depends heavily on your sector, your device and your price. Above all, compare it with your own starting point.

Does my B2B company need a checkout flow? Only if customers can sign up and pay online themselves, as with self-serve SaaS. If you sell services or complex solutions, your equivalent is not a checkout but your form and request flow.

How do I reduce drop-offs without a webshop? Treat your contact and request forms like a checkout: ask as little as possible, make the next step crystal clear and take away doubt with proof. Less friction means more requests.
