Accounting Specialist, AR and Billing (Full-Time and Part-Time Openings)
About Mannix Marketing
Mannix Marketing is a fully remote digital marketing and web development agency based in Upstate New York. Our finance team supports a client base of over 2,000 customers, and we're looking for a detail-driven accounting professional to join the team full-time and own our billing and receivables.
About the Role
You'll work alongside our CFO and accounting team to keep our books accurate, from billing and payments through reconciliations and month-end close. This is a recurring, deadline-driven role. You'll work independently, flag issues early, and look for ways to make routine work faster and cleaner.
Position Details
We have two openings: one full-time and one part-time. Please tell us in your application which you are applying for, or both. Duties are divided between the two roles at hire, so the part-time role will focus on day-to-day payments, billing, and collections, while the full-time role also covers reconciliations, reporting, and month-end close.
What You'll Do
Perform monthly credit card and bank statement reconciliations to support month-end close on schedule
Process incoming payments (paper checks, Authorize.net e-checks, credit card) in QBO and make the corresponding deposits
Run recurring billing reports, distribute them to managers on schedule, and handle new customer billing, changes, and cancellations
Set up and maintain Automated Recurring Billing (ARBs) and recurring transactions, including price updates
Enter vendor and contractor bills in the QBO Vendor Center, collect and file W-9s, and enter referral partner commissions for CFO processing
File employee credit card receipts and enter charges in QBO
Prepare monthly and quarterly reports, including the Tourism billing report, Sales Tax Quarterly Gross Up Report, and ad spend reconciliation
Enter end-of-month commission data and audit commission sheets
Enter scorecard data and complete NYS Contract System audits as needed
Audit domain names and Google accounts billed through Mannix to confirm they are memorized and invoiced
Support collections by sending statements and following up on past-due accounts in the QBO Collections Center
Support year-end tax prep and audits
Build and maintain Google Sheets tracking systems, and recommend automation for routine accounting tasks
Document billing activity and client updates in our company CRM
Participate in regular check-ins with the finance team

Accounts receivable experience, including collections follow-up
