The category management tool can be accessed by retailers visiting www.sparscotland.co.uk, where they can download a selection of planograms that are updated on a weekly basis.
"Feedback has been excellent," said Mike Leonard, CJ Lang trading support development manager. "Our category management team base the planograms around market dynamics, taking into account future trends and current sales movement.
"The space planning software allows retailers to access planograms designed to fit the varying shelving configurations in our estate."
Gordon Landsburgh, who owns several Scottish Spar stores, said the tool helped with stocking the right products, maximising shelf space and profit.
