Your plan sets the listings limit in the Price Monitor page of your account
Meaning – you can publish and end as many listings as you wish on the target website via DSM Tool as long as in the price monitor you do not exceed the amount of listings in you plan.

Credit from your last payment carries on when you are upgrading your plan
When upgrading, your balance from your last payment carries on. Therefore, if you have upgraded your account before your next payment date the "leftover" credit will be used for the new plan payment and you will be charged partially, the next payment date will also change to the new plan first payment date.
When downgrading to a smaller plan your balance from the previous payment does not carry on, instead you will simply not be charged until your next billing date in which you will be charged only for the new plan price.
Supported payment methods
DSM Tool is using a highly secured third party to process payments, the payment options are dependent on the payment methods the are accepted in your country and in the country of incorporation of the DSM company, mostly used payment methods for DSM users are Paypal and credit card.
Changing your payment method
The best way to perform a payment method change is by contacting DSM customer support. The DSM team will cancel your current active plan and downgrade you to a Free account so you could upgrade again with the new payment method.
