After you have paid off your advance credit you can borrow a portion of your credit limit. This is called your available credit. The amount you can borrow will be determined by how quickly you pay off the advance credit. Your balance, or the amount you owe your lender, can be paid off at any time. Each card issuer will have its own methods for compensating your outstanding balance.
Grace period without interest
The interest-free grace period for credit cards is a time between the end of a billing cycle and the due date on your statement when you will not be charged interest on purchases made with the card. The credit card grace period is usually only for new purchases and does not apply to balance transfers or cash advances. After you begin accruing interest on these purchases the grace period ends and you will have to repay your entire balance.
The grace period for credit card holders is different between banks and issuers. You should always check the agreement to determine the length of your grace periods.

Carry-over balance carries an interest rate
You will be charged an interest rate if you have a credit account with a balance which has been carried over from a prior billing period. This interest rate is calculated each day. Calculating the interest rate is based on the average daily balance over a given billing period.
The grace period will end and you will have to pay interest on any balance you carry over. The interest accrues every day until you clear the balance. This is known as trailing interest or residual interest. This applies only to balances that are carried forward from one billing cycle to another. The interest will stop once you pay off your statement balance in full.
Late fees
Late fees are a major source of revenue for many credit card companies. These fees can reach up to 24 percent of your total bill. They are especially burdensome for those who are economically vulnerable. Good behavior can help you negotiate a lower late charge. It is best to pay your bills in full each month to avoid any late fees. You can also setup automatic payments through the bank or card issuer.
If you have missed a payment, call the customer service number at the back of the card to discuss your situation. If you're unable to reach the customer service line, you can also send a letter explaining your situation. Some cardholders have had success sending secure messages online.

There are several payment options
Both consumers and businesses can choose from a range of payment options using credit cards. It can be beneficial to offer a range of payment options to customers if you sell online products and services. One option is recurring billing, which is great for businesses that sell recurring products or services. This type of billing is set up as a mandate and can be used by most credit card providers.
