Invoice Simple bills the job. Workeey also runs the day around it.
Invoice Simple is a clean, cheap invoicing app. It starts at $6.99 a month, or $69.99 a year (checked November 2026), and unlimited invoices cost more. Workeey's free plan includes unlimited invoicing with a pay link, plus your schedule, reminder texts and quick estimates. Here's where each one wins.
The short version
Invoice Simple does one job well. You make an invoice, estimate or receipt on your phone and send it, and the client can pay online. It's cheap to start and easy to learn. It also counts your invoices. The two lower plans cap you at 3 and 10 invoices a month, and only the top plan is unlimited. It has no permanent free plan.
Workeey is for a tradesperson who wants the invoice and the rest of the day in one place. Invoicing is unlimited on the free plan. The same app holds your jobs in time slots, your clients, quick estimates from your own rates and payment reminder texts.
- Pick Invoice Simple if you mostly send a few invoices, want an iPhone app, or take cards in person with Tap to Pay.
- Pick Workeey if you want unlimited invoicing free, plus a schedule and estimates, from your phone.
- Both send invoices with an online pay link, and on both a processing fee applies to online payments.

What Invoice Simple costs
Invoice Simple sells three plans, billed monthly or yearly. Its pricing page advertises the yearly price as two months free. These figures are from its own pricing page, checked November 2026, in US dollars.
It doesn't offer a permanent free plan, though it has a free online invoice generator on its website. On mobile there is a 14-day trial with full access to Premium.
- Essentials: $6.99 a month or $69.99 a year, up to 3 invoices a month.

Where Invoice Simple is stronger
If all you need is to invoice now and then, Invoice Simple is one of the cheapest paid invoice apps, from $6.99 a month. It has iPhone and Android apps and a web version. Clients can pay by card, digital wallet, US bank transfer or PayPal, and Tap to Pay on iPhone and Android lets you take a card in person on the spot.
It also tells you when a client has opened your invoice, with real-time read receipts. It fills in client and item details for you, and its top plan collects deposits. Workeey doesn't collect deposits, has no Tap to Pay or card reader, and has no iPhone app.
What Workeey gives you free
Workeey's free plan never ends and needs no card. Invoicing is unlimited, and one tap turns a finished job into an invoice. It goes out by email from the app with a pay link, and your client pays by card, Apple Pay, Google Pay or US bank transfer through your own Stripe. A small processing fee applies to online payments. Connect your bank and Workeey marks matching invoices paid when the money lands.
You also get 10 payment reminder texts a month, which you switch on per invoice, and 23 quick estimates a month. Your schedule runs in time slots, with repeating jobs and a route to the next client. Pro costs $5 a month and adds Google Calendar and QuickBooks sync. Premium costs $19 a month. Both are billed monthly. See pricing.
Estimates and getting to yes
Both apps make estimates. In Workeey, a quick estimate is priced from your own rates and shared from your phone as a quote PDF. Its Email button opens your own mail app, and the deposit percent you set prints on the quote. There's no online accept step. The client says yes to you, and one tap turns the estimate into the invoice. Read more on estimates, or start from the free estimate template.
Invoice Simple keeps estimates next to invoices and receipts in the same simple app, and its top plan adds client approval on the document. If written approval from the client inside the app matters to you, that's a point for Invoice Simple.
Who should pick which
Choose Invoice Simple if you send only a handful of invoices, work from an iPhone, or take cards face to face. Choose Workeey if you invoice every week and don't want a cap, or if you want your jobs, clients, estimates and reminders in the same app as the bill, without a subscription.
