Best Invoice Apps for Service Professionals 2026: Mobile-First Billing Solutions
You just finished a plumbing repair, and the client asks, “Can you send me the invoice?” You’re still in their basement, tools in hand, covered in pipe joint compound. In 2025, you have two choices: tell them “I’ll send it when I get back to the office” (and they forget to pay for three weeks), or pull out your phone and say, “I’ll send it to you right now” (and get paid before you leave).
