Invoice Mint is an iPhone app for creating, sending and tracking invoices and estimates. It is designed for contractors, service professionals and small business owners, including sole operators and small teams. Users can add business details and a logo, create itemised documents, set tax rates, apply discounts, and track invoice status and payments. A typical workflow is to prepare an estimate for a client, send it for an online response, and record whether the client accepts, declines or requests changes. Accepted estimates can be converted into invoices without re-entering the work details. The app also supports reusable service and material items, saved prices, client records, contact importing, job photos with captions, and client signatures. Users can create and edit invoices and estimates without an account. An account and a Pro subscription or eligible trial are required to send documents or export them as PDFs; these actions use Invoice Mint’s cloud service. Subscription prices and trial terms are shown in the App Store purchase sheet before confirmation.
