Is it possible to make multicustomers in the sales invoice at the same date & in single page ?
A bit of a weird question. You mean 1 invoice for several customers (fiscal entities)? How would you invoice the VAT if there is more than 1 fiscal entity?
No, that is not possible. A sales invoice creates a receivable from a customer for your business. It simultaneously creates a liability for your customer to pay you. Such a transaction can only have two parties: your business and the customer. The same liability cannot be owed to you by multiple parties.
If your real desire is to issue identical invoices to multiple customers (for example, monthly maintenance fees), you can use the clone or copy features. You can also use Batch Create. But in all those situations, you would be creating separate sales invoices for every customer.
Thaks for your support.I realised the situation.
