Werx vs. Invoice Simple: Built to Run the Job
Updated for 2026
Werx and Invoice Simple compared on price, features, and fit.
Invoice Simple is a cheap, simple app for making invoices on your phone. Essentials runs about $6.99/mo, and the top plan is $19.99/mo. It is good at one thing: sending a clean invoice or estimate. But that is all it does. The lower plans cap you at 3 or 10 invoices a month. There is no job costing, no AIA-style or progress billing, no retainage, no QuickBooks sync, and no support for a crew. Werx starts at $49/mo with AIA billing, progress and T&M invoicing, budget-to-actual job costing, two-way QuickBooks, and crew users at $6 each. Honest take: if you are a side-gig or solo handyman who sends a few invoices a month, Invoice Simple is cheaper and fine. The moment you bill a real project or hire your first crew member, you have outgrown it. That is Werx.
