Dear Developer Team,

In Zoho books we cannot convert sales order into delivery challan before making invoices.

As a service business we have to get the delivery note signed then only we can make the invoice.

In Some cases we don't receive a purchase order before the job since its urgent, the only proof that we have is delivery note for the service we did. Kindly consider this option. For now we are creating a delivery challan manually.

Thanks.
