Add-on service

An optional service offered alongside a core engagement, priced and scoped separately from the main contract or retainer.

Example

A branding agency's core package covers logo and style guide; an add-on service for a rush 48-hour turnaround, or ongoing brand-asset production, is quoted and contracted separately.

Why it matters for agencies

Add-ons are a clean way to monetize requests that would otherwise become unpaid scope creep. When a client asks for something adjacent to the core engagement, having a pre-priced add-on ready to offer turns a scope conversation into a quick upsell instead of a negotiation.
