Is this a Mileage Deduction or commuting?

I am a sole member LLC. My principle place of business is my home. I use my home office to expressly write invoices, do bookkeeping, & other admin stuff. My billable work is solely done outside of the home 4x a week for the same fixed client. I bill my travel time. Can I deduct my mileage to and from client or is this considered commuting?
