This is a food catering business. If I buy items for a job (identified by customer name in the system) - how do I attribute cost of items to this job so I can create a profit and loss for every job (customer)?
Eg. Customer XYZ - if I take on a job for $1000 - issue an invoice for $1000 to XYZ. Buy ingredients for this job for $300. How do I attribute the $300 to the $1000 so I can have a P&L for this job with a profit of $700?
