There is no single best route. It all depends on the specific business you are in and at what stage are you today.

To suggest a way, share more details about your product / company. Looks like an B2B focused product. - What is it? - Howz the current distribution - Who are these customers (I mean type) - Why has it took 7 years to get 20 customers? Is your product is very heavy to even evaluate? - Why do you need money and where will you put that (hiring, product development, marketing, distribution, etc)

Wow, thanks. It's predominantly ERP. Customers are top 20 from 1 industry currently (the referral impact) but it's not limited to that trade. It's taken 7 years because I've had to earn a living while developing it and it's a fairly large system. Money is for developer/s so that I can do sales and marketing. What do you mean 'heavy to even evaluate'?
