Compliment slips have multiple benefits and should be a key staple within your business stationery. They are most often attached to something you are sending to a potential or existing customer. This may include an information pack, brochure, samples, or anything else you may wish to send out. Printed compliment slips are also often included as a thank you to your customer for their order. Rather than attaching a note on a scrap of paper, businesses use professional compliment slips that are printed with their logo/branding and contact details.
