Showcasing software skills
The mention of "Implemented a new invoicing system" demonstrates initiative and the ability to improve processes. Be sure to include any relevant software you're proficient in, like QuickBooks and Excel here. Not only does this show your skills, but it can also help your resume get picked up by ATS that screen for specific keywords.
Highlighting accomplishments
The phrase "Recognized for accurate record-keeping and ability to identify cost-saving opportunities" showcases your strengths and achievements. Employers value employees who can save them money and operate efficiently, so it's beneficial to highlight these qualities.
Quantifying financial management
Stating the amount of money you've managed, as in "Managed over $5M in accounts receivable and payable", gives a concrete idea of the scale you're comfortable with. It's also a piece of hard data that can be compared across candidates. This is a good way to stand out, especially if you've handled large amounts.
