B2B SaaS is a software business which sells to business customers instead of ordinary consumers. SaaS is delivered over the internet so users do not have to download any software. In this post we'll go over how to make money with a B2B SaaS, how to build one, how to market it and how to sell it.
How do B2B SaaS companies make money?
B2B SaaS companies charge businesses to access their software on a monthly, quarterly or annual basis. A big advantage of this is that if you run a SaaS, you can use this money to invest in growth by using adverts, SEO or social media to gain more customers. This is especially true of annual pricing plans. e.g. a customer pays you upfront for 12 months in April, which lets you pay for marketing and get more customers over the next year.
The SaaS pricing model also provides businesses with predictable revenue. If you have 1,000 customers paying $30 per month, you can predict reasonably easily what your business income will be each month.

How to grow a B2B SaaS
SEO
There are lots of different ways to grow a B2B SaaS. Search engine optimization (SEO) is a favorite method of a lot of SaaS companies. For instance, Sabba Keynejad, the co-founder of Veed, recommends that founders "build something people search for".
You can hire an SEO freelancer who should do keyword research, analyze your current SEO performance and deliver content that people are searching for e.g. blog posts. One of the benefits of SEO is that it scales well and each piece of content that ranks helps the next piece of content.
PPC
Advertising is another way that B2B companies can grow their SaaS. PPC (pay per click) lets SaaS companies advertize on channels like Google, Facebook and YouTube and they only pay when a user clicks on their advert. If you're good at copywriting, PPC can be a great way to get early users. However, if you are bootstrapping your startup, this may be a costly way to grow and when you stop buying ads, the traffic stops.
Social media
Social media can be great for raising awareness of your SaaS. Many founders have used personal branding to grow their company. A founder with a big social media following can influence people to use their SaaS over competitors if they have a likeable personal brand. Social media sites like LinkedIn and X offer SaaS founders quick access to potential customers.
You can post your own content or you can hire a LinkedIn specialist or X/Twitter ghostwriter

Founders have lots of different options when it comes to selling their SaaS business. Some people use marketplaces like Acquire and Flippa while other will use a broker.
Other SaaS founders have had success from being approached on social media sites like Twitter/X or LinkedIn by buyers. You may also be able to sell your SaaS by announcing your intention to sell on your social media channels or in your newsletter.
