Order feasibility: can you make it before you promise it
Convert the requested quantity into a material requirement, compare each requirement against uncommitted stock, and accept only what the smaller of the two allows. If a material falls short, the order is conditional on a purchase arriving before the delivery date, which makes the date, not the quantity, the real question.
Three answers, not two
Feasibility is rarely a clean yes or no. The three useful answers are: yes from stock, yes if a purchase lands by a given date, and no at this quantity but yes at a smaller one.
Offering the third answer keeps orders that a flat no would lose. Most customers prefer twelve on Friday and thirteen the week after to a polite refusal.
The date matters more than the quantity
A shortfall you can cover in two days is not a problem for an order due next week and is fatal for one due tomorrow. Always check supplier lead time alongside the shortage amount.
Where lead times are unreliable, treat the deliverable quantity as today's capacity and describe the rest as conditional. Saying so in advance costs nothing; discovering it on the delivery date costs the customer.
Never sell the same material twice
The single biggest cause of failed orders in small production is stock counted twice: available for one customer in the morning and again for another in the afternoon.
Deducting materials at the moment of acceptance, rather than at the moment of production, removes the problem entirely. Makeable works this way by default.

Common questions
How do I check whether I can produce 500 units?
Multiply the per unit requirement of each material by 500 and compare with uncommitted stock. Any material where the requirement exceeds stock is the reason you cannot, and the difference is the purchase that would change the answer.
What is the maximum order I can accept?
Your current capacity: the lowest ratio of stock to per unit usage across the recipe. Beyond that number, acceptance depends on a delivery arriving in time.
What software checks whether a business can fulfil an order?
Makeable checks incoming order quantities against live stock and recipes, reports the shortfall per material, and reserves materials when an order is accepted.
Makeable does this calculation live from your own materials and recipes, every time an order comes in. Start free, no card needed.
