What Invoice Simple is
Invoice Simple is an invoice app for phones first, with a web app as well, from Zenvoice Inc. It makes invoices, estimates and receipts, shows read receipts when a client opens an invoice, takes card, PayPal and Venmo payments through Invoice Simple Payments or your own Stripe or PayPal account, and has a bookkeeping section that pulls bank transactions through Plaid. The plans differ mainly in how many invoices you can send per month: Essentials ($6.99 a month) allows up to 3, Plus ($14.99) up to 10, and Premium ($21.99) is unlimited and adds client signatures, premium templates, business summary reports and priority support. Every new user gets a 14-day trial of Premium. The app is listed in 23 languages on the App Store, where it had a 4.9 rating from more than 120,000 ratings on 6 October 2026.
What Invoxa is
Invoxa is invoicing software with one plan. Invoxa Pro costs $5.99 a month or $59.99 a year ($4.99 a month) and includes unlimited invoices, estimates, purchase orders, clients and emails. New accounts get a 3-day free trial without a credit card. Documents carry your logo and brand color on one of 8 templates. Clients open documents from a link without an account, approve and sign estimates, and pay by card, Apple Pay or Google Pay through your own Stripe account. Invoxa runs in the browser and in an iPhone app, in English; an Android app is in development.
Pricing in detail
The two products are priced on different ideas. Invoice Simple sells volume: the price goes up with the number of invoices you may send in a month, and unlimited invoicing costs $21.99 a month. Invoxa sells one plan at $5.99 a month, or $4.99 a month billed yearly, with no counting.
If you send up to three invoices a month, Invoice Simple Essentials at $6.99 is the closer comparison and the two cost about the same. From the fourth invoice a month, Invoice Simple moves you to Plus at $14.99, and from the eleventh to Premium at $21.99; Invoxa stays at $5.99. Over a year, unlimited invoicing is $59.99 on Invoxa against roughly ten months of $21.99 on Invoice Simple Premium with its two free months.
Payment fees are a separate line. Invoxa adds nothing to Stripe's rate (2.9% + 30¢ for domestic US cards). Invoice Simple's fees depend on whether you use Invoice Simple Payments, Stripe or PayPal, and the plan pages do not list them.
