About
FlowInvoice is a plumbing invoice, estimate, and quote app for independent plumbers, plumbing contractors, drain services, repair technicians, and small trade businesses.
Create professional customer documents from your iPhone or iPad. Start with an editable plumbing job preset, adjust the work and local prices, add clear terms, then preview and share a polished PDF.
PLUMBING JOB PRESETS
Build documents faster with editable starting points for service calls, leak diagnosis, faucet and toilet replacement, drain clearing, water-heater work, garbage disposals, sump pumps, fixture installation, pipe repair, repiping, sewer work, and general plumbing labor. Presets never impose prices; add the rates that fit your business.
INVOICES, ESTIMATES, AND QUOTES
- Build itemized quotes and invoices
- Add customers, billing addresses, and service locations
- Add labor, parts, materials, equipment, and custom services
- Set issue, due, and quote-validity dates
- Add tax, customer notes, private notes, and reusable terms
- Preview, print, save, and share professional PDFs
- Record quote approval in one tap with the approval date preserved
- Convert an approved quote into an invoice without re-entering details
- Track draft, sent, accepted, declined, converted, paid, and overdue work
ACCOUNT AND AUTOMATIC BACKUP
Sign in with email and password, Google, or Apple. FlowInvoice keeps invoices, quotes, business details, presets, terms, and Trash history in a private account workspace with automatic Firebase backup and restore. Existing on-device documents are preserved when updating and are copied safely into the selected account.
BUSINESS SETTINGS AND REUSABLE CATALOGS
Set your business details, currency, tax label, default notes, reusable line items, local prices, plumbing presets, and terms. Deleted documents remain recoverable in Trash until permanently removed.
REPORTS AND EXPORTS
Review paid and unpaid invoice totals, pending and missed quote values, filter by date, and export invoice and quote reports to Excel.
FREE AND PRO
The free plan supports up to 10 total invoices and quotes. FlowInvoice Pro monthly or annual subscriptions unlock unlimited document creation. Restore eligible App Store purchases from the subscription screen.
Payment is charged to your Apple Account when purchase is confirmed. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel subscriptions in App Store account settings.
