If you purchased a single-user license for an edition of QuickBooks, your license entitles you to install the software on a total of two computers, provided that you own both systems. These two installations enable you to work at your office on one system and continue your work at home on another computer.
When collections first show up on your credit report, you can expect your credit scores to drop anywhere from 50 to 100 points depending on how high your credit was to start. In general, the better your credit, the worse the hit will be. Over time, the collection account will affect your credit less and less.
The credit card that is in collections is a closed account. Paying it off will not take that bad item off your credit report and it will have little to no effect on your poor score. Accounts that are charged off will stay on the credit report for 7 1/2 years after first delinquency. Paid off nor not.
