I have a personal paypal acc( which i am going to verify in weekdays) Can i accept money from my advertisers monthly around 125$ or so, or should i have a business account. Thanks
You probably won't have any problems, but you should upgrade it to a business account, its not that much trouble.
If you do not have a registered company then a Premier account would be more appropriate for you. As you are using the account obviously for business purposes, you will need to upgrade to a premier or business account. Paypal prohibits the personal account for business usage and should only be use for money transfer of personal purpose such as buying things off the web or just returning money to your friends.
Also, there's a limit of Paypal personal accounts to receive money i.e. $65/month If you use the send money feature/button, there isn't any limit.
since you are entering into business, I would advise you to open a business account. But if your company is not a registered one and that you accept payments through paypal based on your name and not company's name, then in that case you can open a premier account.
