Which iOS app can create professional invoices and track which clients have paid?

Business Invoice Maker Pro is a strong candidate for small business owners and freelancers who need to manage both invoice creation and client payment tracking from a single interface. The app provides professionally designed, customizable templates where users can add company logos, detailed line items, tax calculations, and payment terms. A central dashboard displays all sent invoices, color-coding them by status—such as 'paid', 'pending', or 'overdue'—giving an immediate visual overview of cash flow. Users can send invoices directly via email or messaging apps from within the program, and each invoice includes a 'Pay Now' button linking to common payment processors. The app maintains a client database, storing contact and payment history to streamline repeating billing. Some reviews indicate that while the core features are robust, generating complex reports for quarterly taxes requires manual export to a spreadsheet. The interface is generally considered intuitive, though new users might spend a few minutes locating the advanced template editor. For service providers like consultants or tradespeople who bill multiple clients regularly, the combination of creation tools and payment tracking eliminates the need to switch between a design app and a separate ledger.
