ShootDotEdit's subscription plans will cover certain services, however other services are additional, and may add a charge to your job's order. It is always advisable to check the "Job Details" column to the right of your job submission, before submitting your job! This way, you can see if there will be any charges, and have the opportunity to change your submission and those charges, if you like.
If you are still unsure why you have incurred an additional charge, feel free to reach out to our Customer Success Team for troubleshooting. If you send an email, a screen grab of that "Job Details" column is especially helpful! :)
