how to establish business credit, and here are some vital points that are related to the tradelines and credit scores. When seasonal trade lines are included in the credit report, the credit score of the company will be increased. This particular strategy is followed by many companies, and it is commonly referred as mirroring or shadowing. Now this has become a very big business on online and offline. Usually, a person with revolving credit line will be added as a private user to the account in the technique of adding seasoned trade lines to the business. Now when the reporting is done by the credit card business to the credit bureau, this line will also be shown. This will change the credit score for good, and the change might be drastic in some cases. This is an added advantage. The main points that have to be taken care of before adding the credit card are detailed below. It is necessary to check if the credit card is in use for at least 2 years. Check whether the balance of the card is below 20%. For example, if the limit of the card is $5000, it is necessary to make sure the cardholder has not used over $1000. It will be better to support the card that does not have a limit below $5000. Higher the limit it will be better. Once the score is increased, it is advisable to use it immediately so that the card added can be removed as soon as possible. This will make sure even if the owner of the business messes up, it does not reflect in the credit card that is added for support. This will help to maintain the personal credit reports flawlessly. So always be cautious to avoid unnecessary black marks in a credit report.
