Frequently asked questions

What's the difference between a retainer and a project fee?

A retainer is an ongoing arrangement where the client pays a fixed amount monthly for access to your services. A project fee is a one-time payment for a specific deliverable. Retainers provide predictable revenue.

What happens to unused retainer hours?

This depends on your terms — hours can roll over, expire, or be partially refunded. Define this clearly in the agreement to prevent disputes at month-end.

Can I increase the retainer fee during the engagement?

Yes, with notice. Include a fee adjustment clause specifying how much notice you'll give (typically 30-60 days). Have the client sign an amendment when rates change.
