Maintenance plan
If you would like to always keep Stata software up-to-date, you can include a maintenance plan with your order. Maintenance charges are annual or biennial (for one year or two years), and you get free upgrades to major releases whenever they are made generally available (from the purchase date to the expiration date of the contract). Maintenance may be purchased only when you buy a new license or upgrade an existing one.
With a maintenance plan it also becomes easier to budget for your Stata software expenses. You do not need to anticipate the price of future upgrades and when they will occur.
