This idea has been merged into another idea. To comment or vote on this idea, please visit RAB-I-41 When an Estimate is converted to an Invoice, have the 'Estimate Active' option automatically unticked.
Estimates remain 'active' even when fully completed through invoicing. We do not want the estimates made inactive, but do want them to be shown as fully 'used' when creating an invoice for additional work beyond the original estimate.
