Swift provides a few types of plans:
One-time (30 days use) - SMS included
Annual* (1 year) - SMS included
*Annual plans work best if you plan to use the product for more than 30 days.
Educational plans (billed annually) - SMS included
When you purchase an annual plan, there are four specific things that happen:
These are billed annually - you pay for the entire year ahead - and the price is much lower than what would otherwise be paid using one-time packages:
Savings of 60-70% percent.
You get all the responses up-front - for an annual package, the responses your account receives are 12*(monthly responses) - all added at once after the payment.
The expiration of your package is set to 1 year from the moment of purchase.
The monthly plans renew every year unless requested a cancellation.
