The answer really depends on many factors. You are correct that many SaaS companies valuation falls into the range of 3 to 9 times revenue. I would say that companies that have a very high net income % (25%+) would fall more to the range of 7x-9x and companies that are closer to breakeven or low single digit net income percentages would fall to on the lower range.

Also you need think look at how your company will be viewed from a competitive perspective. If you dominate your market but many many new competitors are entering that may discount the overall valuation. But if you are increasing market share within new market with little or no competition the future looks brighter from a valuation / cash flow perspective due to lower overall cost per acquisition of new customers.
