Sign Installation Business Invoicing App (2026)
For a solo sign installer, ShowTheReceipts ($15/mo) quotes the job in its real parts — permits, lift or bucket rental, fabrication, and install labor as separate lines — takes a deposit to cover materials, and invoices commercial clients on net terms with automatic follow-up.
How we picked
Entry-plan prices as published in 2026, checked against each vendor's own pricing page. Tools were judged on the solo installer's real workflow — multi-line quoting with permits and equipment rental, material deposits, and commercial net-terms invoicing — not on production or fabrication management.

The solo installer’s real workflow
Sign work is custom materials plus rented equipment plus a permit process, sold to commercial clients who tend to pay on their own schedule, not yours.
The deposit protects the materials. The follow-up protects the balance.

Frequently asked questions
What does a solo sign installer need from software?
Quoting that separates permits, equipment rental, fabrication, and install labor; a deposit large enough to cover custom materials; and net-terms invoicing with automatic reminders for commercial clients. Fabrication management is a shop's problem.
What do I get with ShowTheReceipts for $15/month?
Quoting, invoicing, deposits, card payment, and one tax-ready ledger. Automated payment reminders and recurring invoicing are Pro-plan features at $39/month.
How big should the deposit be?
Enough to cover the custom materials, which for a fabricated sign is often 50%. A custom channel-letter sign has zero resale value if the client walks — the deposit is what stops that from being your loss.
