Where Invoice Simple is the better pick
Be fair to it: the mobile apps are genuinely good. If you invoice from the truck, want your history synced to your phone, like read receipts that show when a client opened the invoice, and need deposits or in-app client signatures, Invoice Simple is built for exactly that, and the paid plans are how those features are funded. Frequent senders on the app outgrow the free cap fast, which is the point of the cap.
Where this site fits
Here the trade is different: no cap, no account, no watermark, and the document is the product. Pick a trade in the free invoice generator and the line items load with real starting prices, the totals work themselves out, and the PDF downloads without anything stored on a server. When you want a different look there are 102 designs in the Template Studio, and Word, Excel and PDF templates to download outright.
