Reports
Know what you're owed.
Every open invoice, every payment, every client — at a glance. No spreadsheets. No chasing.
You do meticulous work. Your invoicing should look just as clean. BIG INVOICE lets you create professional, itemized invoices on-site — per room, per coat, per surface — and send them as a PDF before you've finished cleaning your brushes. Clients see clean paperwork. You see faster payments.
Paint jobs get scope creep. A clear written estimate prevents disputes and sets expectations from day one. BIG INVOICE lets you build detailed estimates with your standard line items — prep, priming, labor, materials, travel — and get client sign-off before you start. When the job's done, convert to invoice in one tap.
Whether you're painting a single bedroom or quoting a commercial repaint, BIG INVOICE adapts to the job. Different clients, different pricing, different line items — all organized in one place. Your client list, job history, and outstanding invoices are always at hand.
Painting businesses live and die by word of mouth. A clean, professional invoice is part of the impression you leave. BIG INVOICE produces branded PDFs with your business name and payment terms. It takes a minute to send and says a lot about how you run your business.
