Partial Delivery Without Partial Invoice – How to Manage?

A customer ordered 100 qty.

They need:

  • 40 qty immediately

  • 60 qty after 10 days

But they do NOT want separate invoices.

They want only one single invoice after final delivery.

However, when we ship the first 40 qty, we must reduce stock immediately.

How can this be handled properly?

The correct method is to use Delivery Note before invoicing.
