I am writing bullet points of what is included in a website maintenance service. The way I have phrased the sentence is "Rollover up to 12 Unused Hours". I am not sure if that is correct. How may I use the words "rollover hours" correctly in order to express that if you don't use the maintenance hours we can rollover your hours for next month? Thank you in advance for your help.
I think your original example is pretty clear, but here are some alternatives:
- "Up to 12 unused maintenance hours may be rolled over each month"
- "Up to 12 unused maintenance hours may be carried over into the next month"
- "Unused hours may be rolled over, to a limit of 12"
