Will a startup only focused cloud accounting software work that also provides metrics for the startup? What financial metrics would startups use?

As a CPA/Chartered accountant that's worked in a Big Four Firm, run the finance department at a venture back startup, as well as run my own businesses -- I can confidently say that the only accounting concept that matters for a startup is cash in the bank.

Specifically, how much is there and how quickly is it running out. Everything else really is a distraction as it doesn't matter: when a ship is sinking, you don't care about GAAP compliance.

Metrics matter more for revenue than expenses, which is why this forces the market to be for later stage companies. And those later stage companies have multiple offerings from the mature accounting and management reporting market.

I mentor startups in the product management process so they can make better decisions.

Quite frankly, you are asking the wrong questions. What accounting problem are you going to solve for startups? Without knowing this and verifying it with people that would be potential customers, you can't possibly know whether or not your vision of the solution will work.

I will go one step further and warn you that feedback you get on here about whether or not it will work should be taken with a grain of salt. Always beware of second hand customer validation information. If you need some help getting first hand information, I expect that I can help point you in the right direction.

Cheers and good luck!

A start-up cannot sustain value creation if its most basic and key metrics do not add up. If you are starting a new venture, this is probably all that you are thinking about, turning your vision into reality by building a start-up product that solves customers’ problems and is worthy of their financial commitment. Your KPIs can change as your start-up grows. For instance, when you launch your start-up, new registrations or activations can be an important KPI to evaluate the validation of your start-up idea and viability of the solution in addressing your customers’ needs.
LTV or lifetime value of a customer is the revenue that a customer can generate for your startup over the lifetime of their membership. CAC or customer acquisition cost is the money that you spend on acquiring a customer. CAC includes your expenditure on sales, marketing, and distribution activities.
