It would be amazing for stocktakes to have a chargers tab! We bill $45 an hour for stock takes and I always forget to charge the customer.
This could either Adhoc Charges, or the ability to add manual charges directly to the Stock Take - with the ability to have it flag with a charge error if no charges have been added. (potentially a setting at the rate card level to auto-error $0 stock takes so they're not missed.
