This question is really hard to answer without knowing about what kind of exact B2B business we are talking about.

However it is very easy to split test the whole process. You can use a free solution like Google Optimize or paid tools like: https://vwo.com/ab-testing/

Just make sure to attribute any leads correctly to the test like have a hidden form field with "no-price" and "showing-price" that will be pushed to your CRM, so you can find out the total conversion. Also make sure you get to statistically significant numbers. Most people stop way too early and believe they have found a winner.

Just a word of caution based on my experience with one of my clients. When he added packages with prices, it made things more difficult along the way. My client thought he standardized his service with packages but it turned out he still needed to negotiate various details.

That is because it is very hard to think of every aspect of a complex service and put it in a pricing table on your website. So potential customers asked for extra services, my client did not plan to include in a package. But after the fact it was hard to justify an additional fee because the price was already set in the mind of the potential customer.

I hope that helps and if I can help you with split testing or anything else give me a call.

Best of luck.

Selling in B2B is different. It must inform, persuade, and differentiate. I believe that if there is flexibility in the listing price on your website that would help you more than just mere listing the price. If the list price is "firm," it means that the seller is not willing to negotiate. I believe the CTA via enquiry form is a best option as it gives some degree of flexibility.

Really depends on your business model. Without knowing your particular business and the industry in, it is difficult to come up with a definite answer. However, if you are offering multiple packages, one way to display this is by creating a chart on your website that compares the options head to head. From there, the options (don't include more than 3) can have the prices listed. If there are options that are more expensive, I would create a 4th column that says (please call for custom pricing). That will allow the customer to reach out over large or specialized orders.

Now in the case that you are selling a software that is priced nearly the same as the competitors and they include the pricing, I would include as well. I am in the mindset that being transparent about pricing is the best approach.
