Focus on administrative skills you have; organizational skills/abilities
@Dusti Vilmin The same way you have worked with customers can be used in a restaurant can be used in an office position. For example, communication is one skill that is used on a daily basis correct? With that being said, you can place that skill onto in your resume then in your cover letter provide an example how you have used the skill of communication when going out for a specific job. Another skill used in office management is team work which you can add to the resume then provide an example of in your cover letter how it was used. I hope the above has given you an idea how to write a specific resume to obtain the resume you desire for office management. Good luck!
I would highlight your ability to multitask and problem solve while still having to maintain great customer service. Even in an office you need people skills! The one thing they will be hesitate about would be computer skills, so I would also make sure and share your abilities there. Did you use specific payroll software or scheduling software? POS?
Did you have to close out tills or servers? Take inventory or count money? Did you have to reconcile charges and cash to end of night reports? Managing things takes organization and tremendous people skills. Focus on these things to show how you could shine in an office setting.
You want to highlight your transferable skills, on a resume under your name I would briefly explain what you are looking for like "Proven restaurant manager seeking to my skills to a professional environment" Then a skill section (focused on the skills that they are looking for like Communication, Organization, Problem Solving, etc". Then you want success statements as your bullet points for your jobs. Not just what your responsibilities were, but did you improve sales, build a team from scratch, rebrand or implement a marketing strategy, oversee X number of employees? You use the "professional/office" language to describe your experience so that it's easy for them to picture you in the role. You will probably be able to most easily switch to an office job with a strong customer/client services component.
Thanks everyone for all of the great advise and really helping my confidence!
First let me say your experience is so impressive! You could use 9 years of Restaurant Management to do so much! You must have organized a lot of schedules, creatively put out a lot of metaphorical, and maybe physical, fires in your day too! All of the multitasking and people skills you must have developed would serve you well in many other positions. Let your future employer know how great you are at solving problems and holding a team together cohesively. Good Luck! 💖
