How does annual billing save money?

The annual discount applies to the platform fee, while the included-AI allowance is funded at full value every month.

The discount is 20% off the platform fee; your included-AI allowance is funded at full value every month either way (it’s real usage, not a discountable line item). That works out to about 12% off the yearly total on Pro ($1,046.40 instead of $1,188) and 13% on Business ($3,638.40 instead of $4,188) — see plans and pricing. The allowance still resets monthly on annual plans. Enterprise bills on whatever term its contract sets, so it has no published annual rate to discount — ask us when we quote it.
