Accrual VS. Cash Method of Accounting for Digital (non-physical) Product sales through an Online Marketplace.

Hello,

I sell Digital Products through a couple Online Marketplaces, I am curious if it is necessary that I file using the "Accrual" Method under this circumstance or if I can file it as "Cash", only accounted for when I am actually paid? I will most likely be receiving a 1099-Misc for one of these Marketplaces, if that changes anything.

Thank you!
