Frequently Asked Questions
What is a retainer invoice?
Retainer invoice for ongoing professional services with scope tracking and rollover.
When should I use a retainer invoice?
Use a retainer invoice when the standard invoice format doesn't fit your specific situation. This document type serves a distinct purpose in the invoicing workflow. InvoiceQuickly generates retainer invoices with all the right fields pre-configured.
What's the difference between a retainer invoice and a regular invoice?
A regular invoice is the standard billing document for goods or services delivered. A retainer invoice serves a more specific purpose — it may be issued before delivery, after corrections, for partial billing, or for specialized transaction types. The key difference is in when it's issued and what it represents in your accounting records.
Do I need a unique number for each retainer invoice?
Yes. Like invoices, each retainer invoice should have a unique sequential number for tracking and audit purposes. Many businesses use a separate numbering sequence (e.g., CN-001 for credit notes, DN-001 for debit notes) to distinguish them from regular invoices.
