Job Title: Accounting Manager

Company: Security Equipment Supply, Inc. (SES)

About the Role

Security Equipment Supply is looking for a Accounting Manager who thrives in an environment where the fundamentals of accounting are steady but the opportunities to improve systems, processes, and scalability are constant.

Yes, there are monthly reports and close cycles. But this is not a role where you simply run the same checklist every month.

You'll be working on multiple initiatives at the same time, often at different stages-from improving the close process, to optimizing Microsoft Dynamics 365 Finance & Supply Chain, to strengthening controls and building a more scalable accounting engine for a growing company.

What You'll Do

This role oversees General Accounting, Accounts Payable, and Accounts Receivable while partnering with leadership to ensure our financial infrastructure is built to support meaningful growth.

• Own the monthly close and reporting process with accuracy and discipline
• Work independently without needing constant direction
• Identify process improvements and system opportunities
• Manage multiple projects simultaneously while keeping the core accounting function running smoothly
• Turn complex accounting and ERP processes into practical, scalable solutions

If you're the kind of Accounting Manager who gets things done, improves what's broken, and doesn't wait to be told where to add value, we'd like to talk with you.
