Start with monitoring your employee's performance with your POS till system UK. See what they are selling and not selling. Find if they require more training or a refresher on upselling.
Also, you can use incentives to get more sales contests that motivate your staff with rewards. For instance, an individual with the highest average sales in a week gets an award, or the individual who can sell an 'x' product along with a 'y' product the most times in a month gets rewarded.
