To avoid overdrafts, it is best to keep a small buffer in your account instead of withdrawing it to zero. Do not enable automatic deductions unless absolutely necessary, because sometimes the system processes the money behind the scenes, causing your account to go negative without you having time to react. Monitor your balance regularly and avoid spending beyond your limit. And if you use your account to pay for services, make sure your funds are always available to avoid being deducted when you do not have enough to cover. Being proactive is the best way to keep your account "clean".
