When creating an invoice, it is important to ensure that you have an existing supplier and an executed requisition. This will enable you to proceed with the process smoothly and efficiently. Once you have established this, you can then create either a purchase order invoice or a non-purchase order invoice using the relevant tab. Both options offer their own unique benefits and can be tailored to suit the user's specific needs. By utilizing these tools effectively, you can streamline your invoicing process and ensure that all transactions are handled in a timely and accurate manner.
