Your Outstanding Receivables Are Costing You More Than Money

Unpaid invoices drain your time, slow your growth, and create avoidable stress. We help you take control and get paid faster

Cash Flow Strain

When invoices sit unpaid for 60, 90, or 120+ days, your business can’t invest in growth, hire new talent, or take advantage of opportunities. Your working capital is trapped in aged receivables.

Relationship Risk

Aggressive collections tactics can destroy relationships you spent years building. One wrong approach to a slow-paying client can cost you future business worth far more than the outstanding invoice.

Time Drain

Your team shouldn’t spend 14+ hours per week chasing payments. That’s time stolen from closing new deals, serving existing clients, and growing your business. Every collections call is time your staff isn’t generating revenue.

What Our Clients Say About Us?

George and his team seamlessly took over our receivables process and managed it efficiently. Through their efforts we were able to maintain a low DSO and consistent cash flow for our growing company.

Daniel Murray

CreatorIQ

I strongly recommend George and GK Portfolio Solutions and their services! George was recommended to me by a close friend on the east coast. I was a little apprehensive reaching out to him because he was on the west coast, but that apprehension quickly disappeared once I talked to him and he began working on an accounts receivable collections case for us. We could not gain any progress on collections of payments for a given contract and never had such concerns with any other clients. George was able to quickly obtain responses (where we had not received any responses). He quickly established a payment plan and had our client adhere to a mutually acceptable payment plan! He was able to accomplish our objectives in a professional and respectable manner. I find him to be trustworthy and a man of high integrity.

George Gasparis

The PEER Consulting Group

George’s meticulous follow-up helped us dramatically improve cash flow and allowed me to focus on more pressing items. George is fantastic to work with.
