    Trade Customer Success Story
    “Working with Rainbow Safety has transformed our safety sign sales.”
    Before partnering with Rainbow Safety, our safety sign sales were less than £300 per month.
    With the support and marketing tools provided, our sales have grown to over £3,000 per month.

    Fire extinguisher servicing margins are not what they used to be, so supplying safety signs has become a valuable additional revenue stream for our business. On one warehouse safety survey alone we invoiced £5,100 on a single order.

    We can now compete with internet prices and still make a healthy margin.

    We were regularly asked to supply safety signs, but struggled to compete with internet prices while maintaining a worthwhile margin.

    Working with Rainbow Safety has changed that. We can now offer our customers a competitive range of safety signs while still making a healthy margin for our business.
