Invoicing

Send invoices.
Get paid faster.

Stop chasing checks. Create professional invoices with line items from your price book, send them via SMS or email with a pay-online link, and track every dollar from Draft to Paid.

How invoicing works

From creating the invoice to money in your bank account.

1

Create the invoice

Add line items from your price book, apply tax and discounts. The invoice is ready in under a minute.

2

Send via SMS or email

Send the invoice with a one-click pay link. Customers get it on the channel they prefer.

3

Customer pays online

They click the link, pay by card through Stripe. No login required. Takes seconds.

4

Status updates automatically

Invoice moves from Sent to Paid automatically when payment clears. No manual tracking needed.

Professional invoicing, built in

Everything you need to bill customers and collect payment.

Create Invoices

Build professional invoices with your business branding, customer details, and itemized line items. Add notes, terms, and deposit requirements.

Line Items from Price Book

Pull services directly from your price book with pre-set descriptions, rates, and durations. No retyping the same items on every invoice.

Send via SMS or Email

Deliver invoices through the channel your customer prefers. SMS invoices get opened faster and paid sooner than email alone.

Status Tracking

Every invoice is tracked through Draft, Sent, Overdue, and Paid. See all outstanding invoices at a glance and know exactly who owes what.

Payment Reminders

Automatic reminders go out for overdue invoices. No awkward follow-up conversations. The system handles collections professionally.

Quotes to Invoices

Send quotes with Good/Better/Best options. When the customer approves, convert the accepted quote into an invoice with one click.
