We all know achievements are important on resumes, right? These days it's important to show the reader "what you've done" but also "how well you did it." That's means achievements.
But there's more to it than simply listing your accomplishments - they should be prioritized based on what's most important.
The #1 objective of virtually every retail manager, in the end, is to increase sales and profit. That's why we hire, why we train, why we coach, why we build client books, why we reduce shrink, why we control payroll, etc. The end goal is always to drive sales and profit to higher levels.
So I'm always surprised when I see a resume from someone who has been a store manager with the same company for, say, 5 years and their #1 accomplishment is a spreadsheet they created. Designing a spreadsheet is a decent achievement, but it's not really an exciting one (although it'd be more exciting if it was adopted company-wide). At best, it's maybe a 5 or 6 on a scale of 1-10. It's a bit of a yawner.
The top achievement, ideally, should be something about how successful you were at meeting your sales or profit goals (and there are many, many ways of presenting that, even if you haven't hit your targets).
If you don't include any achievements at all about sales or profit, the recruiter will likely assume you didn't do very well.
Try your best to not let them make that assumption.
