We are an EPC solar contracting company using QuickBooks Online.
For each solar project, we invoice the client for the total project value (e.g., PKR 10 million). After invoicing, we use inventory items (like panels and inverters) during execution. We want to:
Reduce inventory quantities used in the project
Allocate their cost to the project for profitability tracking
Keep the invoiced amount to the customer unchanged
What is the correct workflow in QuickBooks Online to charge inventory at cost to a specific project (or sub-customer), reduce inventory stock, and reflect the expense in the project report — without altering the already issued customer invoice?
Your guidance on the best practice for this scenario would be greatly appreciated.
