After cleaning up a balance sheet that was cluttered with debentures and an inflated stock base, SilverSun Technologies, formerly known as Trey Resources, has nailed down a $750,000 revolving credit line. The company, parent to Sage reseller SWK Technologies, picked up the credit line from a commercial lender late last month. Funds will be utilized for working capital and debt repayment. SilverSun will pay an interest rate of prime plus 2.75 percent annually. The SEC filing on this noted that CEO Mark Meller personal guaranteed payment.
