What maintenance covers
We agree a list, rather than a vague promise of support. Typical items are framework and dependency updates on a schedule, defects you or your customers report, and small content or layout changes that are not a redesign. We check that backups exist and that someone could restore them. We also check the contact path: the form, the WhatsApp link, and the phone number.
A redesign, a new product module, or a new mobile app is not maintenance. Those are scoped as web development, software development, or mobile app development. Mixing them into a retainer makes the retainer meaningless.
