Government funds are available for commercialisation of viable concepts. But existing businesses in the MSME sector have a tendency to consume the "cash in business" for internal research projects.  It creates imbalances in cash flow.  

Apply for government funding support at an early stage of idea/product/technology development.

Market demand is categorised into the local area, city, district, state, country, and global market yearly consumption. Divide the selected market volume by your production capacity. This is your natural market for new products; the remaining is competitors' share. 

If you are ready with a proof of concept, consider market demand size while designing the technology for new products and building the production capacities.

Each manufacturing setup has its own minimum to maximum production capacity. Change in technology results in increased capacities.
