What is email to invoice?
Email to invoice means turning a customer request in Gmail into a priced quote or invoice without leaving the thread. SMASH reads the open email, prices from your catalog, and lets you verify and send from the same reply — typically in under 60 seconds.
Simple as: works with Gmail, Xero, QuickBooks, and as a standalone invoicing tool.

| Separate invoicing app | 5–10 min | Most fields |
| Rough email estimate | 2–3 min | Yes — looks unprofessional |
| SMASH Gmail extension | Under 60 sec | None (voice or From Email) |

Frequently asked questions
Does SMASH work inside Gmail on mobile?
The Gmail invoice extension runs in Chrome on desktop and laptop. For mobile, use the SMASH iOS app for voice invoicing on site.
Can I send invoices without Xero or QuickBooks?
Yes. SMASH generates and sends standalone PDF invoices and quotes. Accounting sync is optional on paid plans.
How is this different from Gmail add-ons like templates?
