How many business cards do you hand out on a weekly basis? Do you even have business cards?
What about your hotel room folders... do they include writing paper for your guests; writing paper that's branded up with your venue's logo and contact details (a letterhead so to speak). Restaurant receipts: how do they look? They are the one item that your customers will take with them when they leave of course. Hopefully the penny's dropping...
Basically, business stationery is a staple ingredient to any company's marketing regime. Especially those that deal direct with members of the public on a day-to-day basis and rely on customer service and good hospitality skills.
Paying attention to these finer details with professional stationery design will make your customers feel like you really care about your brand.
