Branded invoices

Invoices that look as professional as your work

Your invoices carry your brand — logo, colors, business info. Customers see a polished document, not a scribbled note.

  • Add your logo and business details once — they appear on every invoice
  • Itemized line items with descriptions, quantities, and pricing
  • Add tax line items as needed for each job
  • Optional notes, terms, and payment instructions on every invoice

When a customer approves your estimate, convert it to an invoice instantly. No re-typing, no copy-paste errors, no wasted time.

1

Send the Estimate

2

Customer Approves

Your customer taps to approve the estimate. You get notified instantly so you can schedule the work and get moving.

3

Convert to Invoice

One tap converts the approved estimate into a professional invoice. All the line items, pricing, and customer details carry over automatically.

Why it matters

Stop chasing payments

The faster you invoice, the faster you get paid. Service Penguin makes invoicing so quick you can do it from the job site before you pack up your tools.

01

Invoice from the field

Create and send invoices right from your phone while still on-site. No waiting until you get home to sit at a computer.

02

Reduce payment delays

Customers are notified the moment you send. Combine that with one-tap payments and you get paid faster.

03

Eliminate data entry

Customer details, job info, and line items flow from your CRM and job records. Stop typing the same information twice.

04

Look professional

Branded invoices with clear line items build trust. Customers are more likely to pay promptly when the invoice looks legitimate.
