I'm not sure what your business model is or whether you are already making money - $20K is not a lot of money, especially if you have employees working for you - I would say keep a tight hold on money.

As you mentioned you have a market ready product, spend as much as you can on customer validation and getting new customers - invariably would would find you might need the cash flow for the process and scaling up. Cost of sale is often underestimated, and sometimes you will find unexpected expenditure when you thought things are going well. If you are building an enterprise focussed product - you would have to allow at the least 3 months of lead time for getting a customer signed.
