We typically only do 15 or 30 day post launch warranties at no cost especially with native mobile apps as things can break with OS upgrades that may be unforeseen.

For our retainer (maintenance) agreements, it's based on a black of time per month. We usually have a few options proposed with one of them recommended. The client determines which tier they go with based on their budget. Otherwise we charge a flat per hr fee (rounded to nearest 15 min). Hourly is more expensive since it may fluctuate from month to month. For our clients having a fix fee means no surprises for them and they get faster support. For us, it's a guaranteed rev per month.

As far as structure it will vary per customer based on their needs.

When you say fixed fee, am I correct to assume that the number of hours is capped on that? Do your maintenance agreements cover additional features?

I will follow your lead and downgrade to 30 days. Thank you.

Correct. It may be 20, 30 and 40 hrs a month with each for a flat fee. They receive detailed accounting of how that time was used and if they no over that time it's X per hour.
