I have been in business selling a "niche" custom product for many years and now am overwhelmed with demand for my product since putting a website online yet I cannot get any REAL, ACTUAL help or funding to expand operations no matter where I turn. What should I do or where or how can I get the REAL help I need? I have another product designed and ready to be marketed which likely will be even bigger.
I don't think there is a more beautiful feeling than that (on a business perspective).
So there are several strategies you can do take to grow your business without venture capital.
First you need to understand the problem you have: working capital (cash flow). The fastest you grow the more you need cash. (Uber is the perfect example today)
Before implementing any strategy please understand the concept and its implications: cycle of your sales, payment cycle, inventory cycle, etc with this said, my strategies tips:
Factoring: sell of receivables or invoices at a discount. You can "sell" you rights to collect the money to make your payment cycle shorter and be able to reinvest that moeny faster
In advance payment: just literally charge X days in advance so you can make shorter the production cycle or inventory cycle and ship on time, plus growing faster re investing until the next order
Bank: so this guys have several products for this situations: 30 days loan that it automatically renews, "revolver" loan where if you need more you just take it as a line of credit and its decided in small loans each with a specific merchandising as warranty, if you are shipping out of the country you can use and discount an LC, etc etc
There are others that are more risky but I think you can start by analyzing this three and see how they apply to your specific case
