Retainer Invoice
A retainer invoice is a formal document requesting advance payment to secure a service provider's availability for future work. Learn how it differs from regular invoices, when to use them, and their key benefits.
What Is a Retainer Invoice?
A retainer invoice is a billing document issued before work begins, requesting an upfront payment to reserve a service provider's availability for a specific period or project. This advance payment, called a retainer fee, ensures the provider sets aside time for the client and declines other engagements during the retained period.
Unlike regular invoices, retainer invoices are used when:
- Clients need to secure a provider's future availability
- Service providers require financial commitment before starting work
- Ongoing services (e.g., legal, consulting) need predictable cash flow
How Retainer Invoices Work
- Agreement: Client and provider agree on retainer terms (amount, duration, services covered).
- Invoice Issuance: Provider creates a retainer invoice detailing the advance payment.
- Payment: Client pays the retainer fee upfront.
- Service Delivery: Provider reserves time and delivers services as scheduled.
- Reconciliation: Retainer amount may be applied to final billing or refunded if services aren't delivered.
