Approved. One click to invoice.
The problem

The estimate lives in a spreadsheet. The invoice lives somewhere else. Neither knows about the other.

You quote in Sheets or Word. You negotiate over email. You re-type the line items into QuickBooks. You hope the version they approved matches the invoice you just sent.

It’s not a process problem. It’s a missing connection.

Re-entering approved estimates into invoices costs 20+ minutes per deal
And introduces errors on every transfer.

Online quoting software

Online quoting software your team can actually keep up with.

Build a quote in minutes. Send to the client portal. They approve in one click. Versioning is automatic — every revision is saved. Internal sign-off can be required before anything goes out. The whole quote-to-cash loop runs in one place — no spreadsheets, no PDFs floating in email, no “which version did they approve?”

Common questions

What people ask before they switch.

Yes. Send the estimate via the client portal or a secure shareable link. The client reviews the line items, clicks Approve or Decline, and it's logged with their name and a timestamp. No email attachment, no printing, no scanning.
One platform. Every estimate.

Stop quoting by email. Start closing.
