Bug fixes

• Total on workshop jobs with parts on order with a discount was incorrect ,was double discounting.  System would resolve itself normally when parts arrive so rarely an issue at invoicing time. Now calculates correct price on discounted ordered parts
• Credit spares back to stock. Was not creating stock record for unstocked items. Partly a regression bug caused by introduction of unit of measure. An exchange invoice could not restock such items either, now fixed.

Includes new PDF parser library to increase support for importing supplier invoices. At time of writing can import GP Wholesale, Cykel, Yamaha/Ficeda and Whites. Send through more PDFs for us to add.
