Document background
The Estimate Invoice is a crucial business document used in the Philippine market when businesses need to provide detailed pricing information to potential clients while maintaining compliance with local tax regulations. This document type is particularly important as it serves dual purposes: providing a professional estimate of costs while incorporating elements required for proper invoice documentation under Philippine law. An Estimate Invoice should be used when clients require formal pricing proposals that may later be converted into final invoices, especially for projects or services where exact costs might vary. The document must include all elements required by the Bureau of Internal Revenue (BIR), such as TIN numbers, VAT calculations, and official business information, while also clearly stating the estimated nature of the prices and any conditions that might affect final pricing. It's commonly used in industries where project scopes may evolve or where final costs might vary from initial estimates.
