Invoice Simple
Invoice Simple is a functional app for creating invoices and estimates, but recent drastic price increases, reduced invoice limits for existing users, and persistent technical issues with core features like printing, emailing, and payment processing are causing significant user dissatisfaction and churn.
Invoice Simple is an app designed for creating and sending invoices and estimates, with features like payment integration and expense tracking. While many users find it easy to use for basic invoicing, a recent trend of significant price hikes, reduced functionality for long-term subscribers, and unresolved bugs in critical areas like PDF export and customer service has led to widespread frustration among its user base.

Who it's for
Invoice Simple is for small business owners or sole traders who need a basic, easy-to-use app for creating and sending invoices and estimates, especially if they value features like SMS text messaging for invoices R24R27R113. It may be suitable for those with very low invoice volume (e.g., 3-9 per year) who are willing to pay a higher per-invoice cost, or for high-volume users who can justify the significantly increased subscription prices . However, it is NOT for users who rely on consistent pricing, robust customer support, accurate payment processing, or advanced features like multi-currency support, editable sent invoices, or reliable reporting R5R8R20.
Evidence note: The recent reviews skew heavily negative, focusing on price increases and technical issues. While there are positive reviews praising ease of use, they are fewer and often from users who haven't encountered the reported pricing changes or critical bugs. The developer's notes about performance and stability are directly contradicted by numerous user reports of ongoing bugs and instability.

- [R3] This app is easy to use: Like they said simple invoice maker,so powerful and I save the paper
- [R28] Easy to use: I find this app interesting and easy to use
- [R37] Professional and easy: This app makes creating invoices and submitting them and tracking your finances just plain stupid easy. Everything looks as professional as you could ever want and it just makes it easy. Zenvoice nailed it!
- [R113] DAY 1: I’ve been a member with invoice maker for quite a while now, and they first started off with just being very basic which I honestly really liked. It was very easy to use. Since then it’s growing a lot more features have been added and it’s still continues just to be easy to use. Very simple for my customers to be able to receive them through text message and email with signatures. Highly re
- [R24] TIRES DIRECT INTERNATIONAL: I would recommend Invoice Simple to anybody who has a business or starting out. I’m a tire mobile installer and been looking for an Invoice company where I can send my customers immediate pricing etc. most company don’t offer SMS text messaging only by email but Invoice does. This makes closing the sales more attainable rather than a prolong email and awaited response.
- [R27] Great experience: For small business owner works great giving the opportunity to create invoices and quotes remotely from Your phone
- [R35] Great App: Very easy to use, affordable and great for quotes on the go!
- [R153] Love it: Before I’d have to go back to the office and try to remember all the invoice information for the client. I’d forget a lot or just not fill out the invoice. But now I carry my ipad with me and every time I came easy ,ale and send an invoice in seconds for my client.
- [R120] A solid invoice app: I’ve been using it now for about three years and it’s really practical with mobile devices and having PayPal tied in with it to be able to accept credit cards is really cool even though you do have to pay fees. The report section works well for end of your taxes, and the deductions and scanning receipts is really practical and keeps it all in one place. Also, you can login dir
- [R1] Terrible!: I have had this app since 2018 It’s impressive how bad this app has become. -They keep raising the price of the app -They have now reduced the amount of invoices I can make each month so it’s not viable for an actual business -I have to modify invoices several times to get them to save (took 10 mins and 8 attempts to mark an invoice as paid) Very disappointed, at one point this a
- [R2] App is good but: The app is good, support is ok when it goes down, no customer service phone Have been using it for 4 years and every year a price increase started at $99.00 then 149.99 and now $219.99 a 47 percent increase (Crazy)especially for a small business
- [R7] Prices to high: I’ve had this app for many years now. They keep rising their prices every month it seems now. Leaving the app now. Smh
- [R10] Invoice: Use to love this app first couple years then more recently I’d pay for a year then the number of invoices I can write changes during my subscription and went from $100 to $200. Will not renew
- [R6] Greedy: I’ve been paying for this app for years. They recently reduced the number of invoices per month to THREE. That’s PAID. The upcharge is ridiculous. This doesn’t need to be a subscription in the first place. It’s a static tool. They already try and push you to use their billing services and take a cut. Now they’re pushing the subscription tiers by reducing offered services to existing users.
- [R17] Keeps saying I have 0 invoices left: This used to be a great app until they did something in the backend because now I constantly keep getting a message that I have 0 invoices left when I pay monthly for unlimited. Keep in mind I pay for 2 accounts because I have 2 shops and each time they want me to delete and uninstall to fix. It has been so constant that I am ending my subscription and will war
- [R5] Terrible customer service: I have used this app for years and also purchased the unlimited version. But as of 2 months ago I can no longer print or email any invoices/ estimates to my clients. All I get is an error message. I’ve deleted and reinstalled the app a dozen times now and it’s the same thing everytime. I’ve reached out to customer service a few times now and all they say is the back end
- [R8] DON’T BUY: No support. Been waits weeks for them to fix a problem they acknowledged
- [R9] Wolfe: What ever you do don’t buy the Invoice Simple. I’ve given them more then a month to fix an issue & it still hasn’t been fixed. They don’t have any back end support. Which means if you have a problem they have no way to fix it. I’ve had the app since 2018. Running 2 companies with it. Recently I had multiple problems with it over a several week period. I made them aware of it with over a d
- [R11] Charged me $199.00 and never activated my account again.: Be careful with this company when they renew your membership, they charge you $200 and then the system will never let you create an invoice without upgrading. There’s no need to upgrade. I just paid you. I had talked to Customer Service and they have given me no answers. I am still without $200 and just basically communicating with AI. Buye
- [R16] Major bug: Something is wrong it won’t let me print or send pdf every new invoice or estimate I have to delete and download the app to send each invoice or estimate
- [R130] Invoices go to spam: Multiple clients have told me their invoices ended up in spam. I tested it myself, same result. 📬 This is a professional tool, and the fact that your emails aren’t authenticated properly is mind-blowing. You’re literally killing my cash flow. I shouldn't have to follow up to make sure someone even got the invoice.
- [R20] Stop with stripe: Why are you using a company for our payouts that we are not able to communicate with? Stripe is always slow, late and not user friendly. Some people can’t use PayPal so I’m sending them square links or Zelle. Like come on. I love using the invoice system but loosing out on fast payouts is frustrating.
- [R29] The worst app I’ve ever used.: The invoicing process is actually simple, but they charge outrageous fees and they hold your money hostage for way too long, which is really bad for business. I’d use literally anyone else and if you see this app run the other way.
- [R36] Used to be good, trash now: Gotten unrealistic expensive. If your paid through there invoice it takes days get the money and the fees are crazy. Now you get 10 invoices a month and you’ll have to buy more if needed. Garbage. I’ll be moving all my contacts and will start making my invoices on quickbooks app.
- [R42] Scam and liars: Avoid this platform. They will refund and give back money to customers. On the 13.99 they give you 10 invoice per month then you have to pay for more. Not to mention taking a percentage of each invoice and they’re also taking another percentage just to transfer it to your bank immediately and then they’re making another transaction from stripe or PayPal to your bank account so you’
- [R46] Gradually getting worst: I’ve been using invoice simple since 2018. Noticing over the years with each update the app is becoming less and less responsive. Noticing lag as I process each Invoice and sometimes it crashes by giving me and error message. Going to cancel my subscription after next month.
- [R54] LOCKED UP FOR THE PAST WEEK: It WAS great until it locked up. No access to my invoices and could not create a new one. I tried everything including reloading. CAUTION if you cannot afford to not access or send invoices.
- [R176] This programs math is sometimes incorrect otherwise good: It took months to figure out that the balance due on some invoices are incorrect! Customers have gotten away with paying anywhere from $100-$200 off what was saposed to be due on the total! On the plus side customer service is INSTANT. They are trying very hard to get this app 100%
- [R133] Can't change currency: I work internationally and this app doesn’t let me change the default currency for different clients. Are you kidding me? 🌍 I’ve lost deals because the invoice shows the wrong currency symbol and there’s no way to fix it per client. The one-size-fits-all logic makes no sense in today’s global market. Unusable for anyone outside the US.
- [R136] Limited item library: There’s no efficient way to store or manage frequently used products or services. Every time I make an invoice, I have to retype the same items. 🤬 A basic item library is industry standard. Even free tools have that. This app just isn’t built for professionals who do high-volume invoicing. Wasted so much time on repetitive input.
- [R138] Can't edit sent invoices: Once you send an invoice, you’re locked out; Client wants a small change? Too bad, you have to void and start over. 😒 That makes me look sloppy and unprofessional. Just let us edit and resend, it’s not rocket science. This is supposed to be a flexible invoicing tool, but it’s clunky and rigid. Feels like I’m using software from 2005.
- [R129] Dashboard makes no sense: The dashboard is an absolute mess. You’d think it would show key metrics at a glance, outstanding invoices, top clients, month-to-date incọme. Nope. Instead, it’s just cluttered boxes and graphs that don’t even update correctly. 🧱 Half the time, the totals are wrong, and the layout changes after every update. It’s like they’re trying to confuse you. I don’t need flashy vis
- [R139] Reporting is broken: One of the main reasons I got this app was to generate reports for tax season and monthly overviews. But the reports are so badly designed, I still end up dumping everything into Excel and doing it manually. They don’t filter right, half the totals are wrong, and nothing exports cleanly. 😬 Also, why does the app crash when I try to generate an annual summary? That’s not a bonu
