## What is Invoice Manager?

Create invoices, organize client details, and keep your billing records under control—all from your iPhone or iPad.

Invoice Manager is a simple, private invoicing app designed for freelancers, independent professionals, contractors, and small businesses. It gives you the essential tools to prepare detailed invoices without complicated accounting software, subscriptions, or online accounts.

CREATE DETAILED INVOICES
Build invoices with custom document numbers, issue dates, due dates, currencies, and notes. Add as many line items as you need, then enter quantities, unit prices, discounts, and tax rates.
Invoice Manager automatically calculates each line total, subtotal, discount, tax, and final amount, helping you reduce manual calculations and avoid common mistakes.

KEEP CLIENT INFORMATION ORGANIZED
Save client names, companies, email addresses, phone numbers, and billing addresses in one place. Search your client list and quickly select an existing client when preparing a new invoice.

CUSTOMIZE YOUR WORKFLOW
Set your default currency, tax rate, and payment terms so new invoices start with the details you use most often. Customize invoice numbering with your preferred prefix, starting number, and number format.

Add your business name, contact information, logo, and accent color to keep your company details organized. You can also choose between A4 and US Letter document preferences.

Choose from USD, EUR, GBP, CAD, AUD, JPY, and SGD

PRIVATE BY DESIGN
Your invoice, client, and business information is stored locally on your device. Invoice Manager does not require an account, cloud service, third-party integration, or internet connection.
Whether you send a few invoices each month or simply need a clearer way to organize your billing records, Invoice Manager keeps the process straightforward, focused, and private.
