Staxen vs Invoice Simple: what $59 buys over $6.99
Invoice Simple is exactly what the name says: a clean, cheap app for making invoices and estimates from your phone, starting at $6.99 a month. Staxen is AI employees that write the estimate from your voice, collect an e-signature and deposit, invoice in stages, and chase overdue payment on their own, at $59 a month per employee or $149 for all three. Invoice Simple is cheaper by roughly eight to one. What the difference buys is the labor, not the paperwork.
What Invoice Simple is
Invoice Simple is one of the most popular invoicing apps for small businesses and independent contractors. It makes professional invoices and estimates in a couple of minutes on a phone, takes online payments, shows read receipts when a client opens an invoice, and keeps simple reports. Plans are priced by invoice volume, and the whole thing can be learned in an afternoon.

As of September 2026, Invoice Simple charges $6.99 a month for Essentials (up to 3 invoices), $14.99 for Plus (up to 10), and $19.99 for Premium with unlimited invoices, or $199.99 a year. Staxen is $59 a month per AI employee or $149 for all three. If your invoice count fits inside Invoice Simple's caps and you do not mind typing, it is the cheaper tool by far; Staxen's price covers the drafting, deposits, reminders, and bookkeeping sync that the $6.99 app leaves to you.
The honest verdict
For a side-hustle contractor sending a few invoices a month, Invoice Simple at $6.99 to $19.99 is the rational choice and Staxen would be overkill. The gap appears when the paperwork becomes the job: Invoice Simple caps its cheaper plans at 3 and 10 invoices a month, does not draft anything for you, and leaves collections to you. Staxen's Eddie writes the estimate from a spoken description, clients e-sign and pay a deposit on one page, and Ivy escalates overdue reminders without being asked. The tradeoff is $6.99 for a document maker versus $59 for a document maker plus the person who fills it out and follows up.
Pick Staxen if

Pick Invoice Simple if
A part-time or just-starting contractor who sends a handful of invoices a month and wants them professional for the price of a coffee.
Why contractors move from Invoice Simple to Staxen
You outgrew the caps
Three invoices a month on Essentials or ten on Plus disappears fast for a working contractor. Staxen has no invoice caps on a paid plan, and the pricing does not climb with your volume.
Estimates that close, not just look good
Invoice Simple makes a tidy PDF; the client still has to print, sign, or email back. Staxen's estimate is a link the client e-signs on their phone, with a deposit collected the same minute.
Someone chases the money
Read receipts tell you the client saw the invoice and ignored it. Ivy sends reminders that escalate as the balance ages and takes card or ACH on the portal link, so awkward follow-up texts stop being your job.
Your books stop being a shoebox
Invoice Simple lists no QuickBooks sync. Staxen pushes estimates and invoices to QuickBooks Online when you send them and pulls payment status back, so tax season starts organized.
Frequently asked questions
Is Invoice Simple or Staxen cheaper?
Invoice Simple, by a lot: it runs $6.99 to $19.99 a month as of September 2026 while Staxen is $59 per month per AI employee or $149 per month for all three. Staxen's first job is free with no card required and no time limit, but on ongoing cost the invoice app wins. The honest question is whether you want a cheaper document or fewer hours making documents.
Can I switch from Invoice Simple to Staxen?
Yes, with a small amount of manual work. Export your client list as a CSV and import it into Staxen, and forward any open estimates or invoices into it as documents; there is no one-click migration. Because Invoice Simple is month to month too, most people just start their next job in Staxen and let the old app lapse.
How many invoices a month before Invoice Simple's caps matter?
The Essentials plan allows 3 invoices a month and Plus allows 10, as of September 2026. A full-time contractor billing deposits, progress draws, and finals on even four or five active jobs clears 10 documents quickly, which pushes you to Premium at $19.99 for unlimited. That is the point where comparing against fuller systems starts making sense.
What should be on a contractor invoice?
Your business name and license number where required, the client and job address, an itemized scope with quantities and prices, the invoice date and a specific due date, accepted payment methods, and your late fee terms. Vague one-line invoices get paid slower and disputed more. Whatever tool you use, the itemized version wins.
Do deposits actually reduce no-pay jobs?
Yes, meaningfully. A client who has paid 20 or 30 percent up front almost never walks away from the balance, and the deposit funds materials so you are not floating the job. The friction is collection, which is why putting the deposit on the same page as the e-signature, the way Staxen does, beats requesting a check later.
