Website maintenance retainers provide predictable income, but pricing them requires understanding the real ongoing time commitment involved.
Define the scope precisely
Specify exactly what's included: security updates, backups, uptime monitoring, minor content changes, plugin updates — vague scope leads to scope creep on a fixed monthly fee.
Estimate realistic monthly time
Base your price on a realistic average monthly time commitment, accounting for occasional urgent issues that take longer than routine maintenance.
Set a cap on included changes
If minor content updates are included, cap the number or time allotted per month, with anything beyond billed separately at your hourly rate.
Price emergency support separately
If your retainer doesn't include emergency after-hours support, be clear about this and offer it as an optional add-on or separate hourly charge.
Invoice consistently each month
Bill the retainer on the same date every month regardless of how much active work was needed that period — this is the nature of a retainer model.
Review pricing periodically
As a site grows in complexity, or as your own rate increases, revisit whether the retainer price still reflects the real time commitment involved.
