Why supply matters to a first-time founder
Supply affects whether customers can buy when they want and how prices respond to scarcity or excess capacity. Founders need to distinguish demand problems from an inability to produce or deliver. Capacity, input prices, regulation, technology and seller expectations can all change the quantity offered.
Examples of supply
At €20 per unit, five local producers together offer 10,000 units a month. At €25, they can profitably add shifts and offer 13,000. Those quantities describe points on market supply, assuming other conditions stay similar. A factory closure would instead shift available supply at each price.
Common misunderstanding
Supply is not the amount currently sitting in a warehouse. Inventory is one source of available goods, while economic supply describes how much sellers are willing and able to offer at different prices during a period. It also differs from quantity supplied, which refers to one specific price.
When to use it
Use the concept when analysing pricing, production capacity or market shortages. Define the market, location and time period, then examine how much sellers can offer at relevant prices. For operating decisions, combine market analysis with actual lead times, inventory, supplier commitments and constraints rather than relying on a simple curve alone.
