Frequently Asked Questions
What is a interim invoice?
Interim invoice for partial billing during long-running projects with progress tracking and retention.
When should I use a interim invoice?
Use a interim 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 interim invoices with all the right fields pre-configured.
What's the difference between a interim invoice and a regular invoice?
A regular invoice is the standard billing document for goods or services delivered. A interim 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 interim invoice?
Yes. Like invoices, each interim 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.
