Pricing watch-outs

Contract questions to ask before you sign
  1. Does the plan auto-renew, and how many days’ notice do you need to cancel?
  2. Is the advertised price for annual billing? What is the month-to-month price?
  3. Is the first-year price a promotion? What will renewal cost, and is it capped?
  4. Is there a minimum number of seats, or a charge for inactive users?
  5. Are onboarding, implementation or premium-support fees extra?
  6. How do we export all our data if we leave, and in what format?
