The deal will cover all UK domestic customers.
TSP has already been supplying selected retailers since Autumn 2008, but will manage all domestic business for 2009 and beyond.
Dave Martin, IW Commercial Director commented: "We are delighted to be working with James Triptree and the Sales Partnership organisation. Whilst we will continue to supply the majors directly on FOB terms, Sales Partnership will further develop the IW business through their tremendous network of independent and domestic customers.
"This partnership makes perfect commercial and financial sense - we have managed to re-align logistical costs and offer domestic customers good margins on key licenses in key electronic categories. We needed better retail distribution in view of new licenses we have acquired this year, and Sales Partnership are the right organisation to deliver against our objectives.'
InspirationWorks 2009 licenses now include Peppa Pig, Postman Pat SDS, Thomas & Friends, and Dora the Explorer in Pre-school Electronic, and Puppy in my Pocket & Friends and Disney Princess & Fairies in Girls Electronic.
