About us
The Receivables Agency, formerly known as GK Portfolio Solutions, was founded in 2013 by George Kaiteris after recognizing a critical gap in the receivables management process within the market research industry. After being let go from his job, George took a leap of faith, using his first unemployment check to purchase a basic laptop and begin reaching out to market research companies that were struggling with aged invoices and unpaid accounts.
Within just two months, he had secured enough clients to establish what would become a thriving receivables management company.
What started as a bold idea has since evolved into a multi-industry solution. After the first year, George expanded the company’s services beyond market research to include media and advertising agencies, accounting firms, trucking companies, cannabis distributors, and more. By collaborating with accounting partners and CFOs, we became a trusted white-labeled partner—representing clients seamlessly as if we were part of their internal team.
Over the past 12 years, The Receivables Agency has recovered over $500 million in outstanding receivables, significantly reduced Days Sales Outstanding (DSO), and helped countless businesses improve cash flow and financial efficiency. In 2025, we rebranded to better reflect who we are and what we do: a dedicated, professional, and results-driven receivables agency.
Our mission is simple—help businesses recover what they’re owed without compromising relationships or overspending on in-house staff. With us, clients get an experienced team—not just a body—at a fraction of the cost. Whether you're a startup or an established enterprise, The Receivables Agency delivers tailored accounts receivable services designed to scale with your business.
Let us turn your unpaid invoices into paid results.
