When you’re building your own board it’s really difficult to understand how it can translate into a viable business – starting up cashflow is king, no cash, no business. You’ll say to yourself, self, I built this board I can probably sell it for 50% more than what I paid for parts. What you’re not accounting for is your time, shipping, taxes, warranty, services, compliance, marketing, inventory storage, sales, web presence, the list goes on. If, by yourself, you think you can sell your product at a 2-3x margin on materials I think you have a shot - if not, you need to be able to negotiate down prices with your suppliers or find a way to make things for cheaper and insure you have the sales pipeline to sustain whatever volume purchase you made. That profit margin talked about will shrink as you grow to about 20% if your lucky, lower if you’re not.
The easiest way to start is to sell services – you have low capital investments to do that. Moving into the product space is a whole different game. Most people don’t understand the capital it takes to bring a CPG to market.
