For a SAAS product company, do medium or large size clients pay using credit cards .

It's not foolish, but it's going to be extremely hard to pull it off. I would consider starting with a beta program so you can have some paid clients to pay for the company's expenses. After you have some traction, you can raise a seed round.

The idea of an MVP is 'minimum, viable' ... If you feel you need a "good amount" of funding, I would challenge if you are minimum enough. Obviously, without knowing the details of your product, your ideal customer, or what need you will solve, it is hard to help expose what is necessary in an MVP and what is a Phase II or Phase III feature. I am happy to help you work through this, or answer specific questions, to get you rolling. Just book a call with some times that will work for you. Regardless, I would love to know more about it and how it goes after launch. To your success, -Shaun

Yes, I did exactly that a few years back. A friend of mien and I launched a site with minimal functionality that was really just a landing page. We offered the opportunity to pre-buy a year's subscription to the service by allowing users to set their own pricing. Within the first 24 hours of the site going live, we had enough paying customers to validate the business and inform our iterative development cycle. Ultimately, we decided it wasn't a big enough business for either of us to get really excited about but it proves that it can be done. I also did that in my current business with a landing page that generated literally thousands of leads and hundreds of very qualified customers, which resulted in paid pilot contracts before the software was fully built. Build something that people actually *need* and you'd be surprised at what they're willing to do to get early access to it. Happy to talk about it in a call in more detail

In my experience, the longer sales cycle requires more attention. The metrics will be unique to your business, but you can't go wrong with these: Marketing & Sales Metrics Look at metrics that will help you scale and project growth, and then accelerate opportunity to close velocity #s and conversion rates of marketing qualified leads (MQLs) #s, time, and conversion rates of MQLs to sales qualified leads (SQLs) #s, time, and conversion rates of SQLs to opportunities #s, time, and conversion rates of opportunities to sales Customer Success Metrics An ARR SaaS business may have a guaranteed 12 month customer lifespan, but that doesn't guarantee the customer actually uses the product and won't churn at renewal time. Measuring product usage will help you discover patterns that cause churn, increase the perceived value of the product, and improve the customer experience. Financial Metrics Each Reporting Period (I'd recommend monthly) look at Values & Rate of Change Customer Acquisition Cost Average Value of a Customer look at Values, % of total, & Rate of Change Revenue from New Subscriptions Revenue from Renewal Subscriptions At the early stage, businesses will see new Subscriptions significantly outpace renewals. As the business matures, the % of total ARR from New Subscriptions will begin to decline, assuming churn rates are good.
