Software Contractor Invoice Template

I need a Software Contractor Invoice Template for my Singapore-based freelance development work that includes GST calculations and allows for both hourly and project-based billing, as I provide both types of services to different clients starting January 2025.

What is a Software Contractor Invoice?

The Software Contractor Invoice Template is essential for independent software developers and consulting firms operating in Singapore who need to bill clients for their services. This document ensures compliance with Singapore's tax laws, including GST requirements where applicable, and provides a professional format for billing software development, maintenance, and consulting services. The template includes necessary fields for contractor details, client information, service descriptions, and payment terms, while maintaining flexibility for both time-based and project-based billing structures. It's designed to meet IRAS requirements and facilitate proper record-keeping for both parties.
