## What is Invoice Maker?

FieldFlow is a simple invoicing app for contractors, handymen, cleaners, landscapers, electricians, plumbers, and other small service businesses.

Create clear business documents in minutes:

- Create quotes and invoices with line items, quantities, rates, discounts, taxes, notes, and payment terms.
- Save customer and job details once and reuse them for future work.
- Convert an accepted quote into an invoice without re-entering the details.
- Record full or partial payments and track outstanding and overdue balances.
- Generate professional PDF documents and share them through the standard iOS share sheet.
- Prepare payment reminders and choose when and where to send them.
- Export your workspace as a JSON backup.
- Delete your workspace and business data directly from Settings.

FieldFlow requires no account. Your workspace is stored locally on your device. The app does not send messages automatically; you choose the recipient and sharing destination in iOS.

Start free with limited clients and documents. Upgrade to FieldFlow Pro for unlimited clients and documents and watermark-free PDFs.

FieldFlow Pro is an optional auto-renewable subscription available monthly or annually. Payment will be charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple ID settings.
