Services Offered

Accounts Receivables management

At times, businesses are not able to devote the proper amount of time and resources required to take on the daily tasks of managing their receivables. They need a solution that they can rely on to help improve cash flow, decrease the DSO and stay in contact with each past due client, this is where we come in. We contact our client’s customers on our clients behalf and help resolve each outstanding invoice.

credit management

When a company extends terms for services rendered or goods sold the company becomes the lender and the customer becomes the borrower. It is vital to know and understand a customer’s ability to pay on time and their past payment history. We have access to the best sources to check on a customer’s credit history and make recommendations.

Accounts payables management

Outsourcing your accounts payable is a viable solution for companies of any size. Trying to manage your own AP could be a daunting process. Allow us to take that stack of invoices off your desk and get them ready for digital approval and paid electronically. With so many cloud-based options managing your payables will be seamless and easy.

collections referral service

Placing customers in collections is what each company dreads but it is something that companies face each and every day. We first try to resolve the matter directly with each customer through our company and if unable to reach a satisfactory arrangement we then discuss the matter directly with our client and with their consent we will refer the non-paying customer to the collection agency we have partnered with for further activity and resolution.  

Billing & Invoicing

Processing your monthly invoices could cost you more money if it is not processed efficiently and on time. We understand the significance of a company’s billing & invoicing process and the direct effect it has on the company’s ability to grow and thrive. Outsourcing the invoicing process can free time for the staff so they can take on additional tasks associated with the company’s  day to day operations.

consulting & referral services

We understand at times a company cannot outsource their receivables but additional short-term help may be needed. We can come in and review your current process and make recommendations on how to improve and provide solutions as well. Additionally, we have partnered with top notch payroll companies, bookkeepers, accountants and interim CFO’s to help provide additional support for all of your accounting needs.


The only way to do great work is to love what you do. If you haven’t found it yet, keep looking, and don’t settle.
