Invoice Splitter

Split invoices by team member, project, or department with transparent math.

Last validated: 2026-02-14

Use this free online Invoice Splitter to allocate an invoice total across people, teams, or projects using transparent split rules. Use it for budgeting, pricing, forecasting, and comparison work where small input changes can materially affect the final decision. The form focuses on Subtotal ($), Tax (%), Discount ($), Allocations (Name:Percent) and returns Invoice Split Inputs, Allocation Results, so you can move from input to answer without setting up a spreadsheet or custom script. Run one realistic example, adjust the inputs, and compare how the result changes before you copy or share it. The output is an estimate rather than financial advice, so confirm assumptions, taxes, fees, and policy details before making commitments.
