Bookkeeper/Administrative Assistant

IGY SIX Consulting is recruiting on behalf of Vertex Security for a hands-on Bookkeeper to join its Manhattan office.

This role is ideal for someone who has worked in a small construction, security, trades, or service-based business and is comfortable wearing more than one hat. The right person will have strong QuickBooks and bookkeeping experience, understand accounts receivable and collections, and be comfortable helping with the day-to-day administrative needs that come with running a busy office.

Vertex Security is looking for someone who can take ownership, stay organized, troubleshoot issues independently, and work closely with ownership, operations, and project teams.

What You’ll Do

• Manage accounts receivable, collections, aging, reconciliations, and customer follow-up
• Maintain a high volume of open invoices and customer accounts
• Work in QuickBooks to process transactions, research discrepancies, reconcile accounts, and maintain accurate financial records
• Support accounts payable, vendor payments, and general bookkeeping responsibilities
• Investigate billing issues, payment discrepancies, and account questions through resolution
• Communicate directly with customers regarding balances, invoices, payments, and account status
• Maintain accurate daily and weekly financial reporting
• Work closely with ownership, project managers, operations, and office staff
• Research and respond to administrative matters involving state agencies, unemployment notices, DMV issues, insurance documentation, and other business correspondence
• Assist with vehicle records, insurance matters, mail, vendors, and general office administration
• Maintain organized customer, vendor, employee, and company records
• Handle multiple priorities and take ownership of issues that fall outside the normal process

What We’re Looking For

• Hands-on bookkeeping experience in a small business environment
• Strong working knowledge of QuickBooks
• Experience with accounts receivable, collections, reconciliations, invoicing, and accounts payable
• Experience supporting a construction, contracting, security, trades, or field-service business strongly preferred
• Comfortable working with project managers, field operations, vendors, and company ownership
• Strong attention to detail and follow-through
• Able to manage a large number of open items at the same time
• Strong written and verbal communication skills
• Ability to research unfamiliar issues and find solutions independently
• Comfortable shifting between bookkeeping, office administration, and operational support
• Experience in an Office Manager, Bookkeeper, Accounting Administrator, or similar small-business role is a strong fit

The Right Background

This is not a narrow corporate accounting position.

The strongest candidate will likely come from a smaller construction, contracting, security, trades, or service business where they were responsible for more than one function.

You may have handled bookkeeping, AR, AP, insurance paperwork, vehicles, vendor issues, office administration, customer follow-up, and whatever else needed to get done that day.

If that sounds familiar, this may be a strong fit.

What Success Looks Like

Success in this role means keeping the books organized, staying on top of receivables, reducing outstanding balances, maintaining accurate reconciliations, and making sure administrative issues do not sit unresolved.

If you are a problem solver who takes ownership, knows how to research an issue, communicates clearly, and follows things through to completion, you’ll fit well in this role.
