  1. [R3] Invoice2go 3/5 · US Would be 5 stars except it gets bugged out every time they change the app was great originally: Super easy to bill on the go. Easy to navigate, saves clients for repeat business. Saves pricing for any items or tasks. Saves labor and material rates. Even adds tax if necessary. Love it have been using for over a year. Would not ever even think about going back to hand written or typing up an invoice
  2. [R6] Invoice2go 3/5 · US Aggravating: Open then close to open to get it to work. Not sure if anyone looking for an invoice/estimate app if you won’t the aggravation of this app.
  3. [R19] Invoice2go 2/5 · US Do not like: I had this app for about a year ! And it went up on the prices since I had it . It’s always freezing up making me redo an invoice. It’s becoming an issue with glitches . I’m about to cancel !
  4. [R21] Invoice2go 3/5 · GB Adequate: I have subscribed for several years now. Simple and unfussy though here are just two suggestions to improve it - 1. Be able to attach PDF’s to invoice as only jpegs can be uploaded currently. I requested this a while ago and still not available. 2. Be able to have multiple currencies in multiple invoices without having to set a currency default. A simple drop down menu would help. 3. Bul
  5. [R8] Invoice2go 5/5 · US Invoicing: Make invoicing a quick and easy process
  6. [R17] Invoice2go 5/5 · US Easy to use.: Easy to make invoices and just as easy to keep track of when they are seen by costumers as well as when they are payed.
  7. [R1] Invoice2go 1/5 · US Closed my account with explanation: Getting any information from them in regards to Payments will be impossible. They had me wait for 2 days stating my payment will be available then without notice they closed my account with no specific reason. The worst invoice company ever!
  8. [R4] Invoice2go 1/5 · US Terrible: They will pull money right out of your checking account without warning. Be careful there are better apps out there such as quickbooks. They do not have good customer service either and you cannot get a hold of them. One transaction was $375 and another transaction was $3500 gone. Scammy tech company and I am very disappointed with them and the company Bill. Garbage
  9. [R12] Invoice2go 3/5 · US Update: Nice app just a little pricey, but would be nice if you could take note and make phone calls from each customer profile while recording all communication for customers
  10. [R15] Invoice2go 3/5 · GB Overpriced: Not really happy I have paid for the subscription of £8 per month and it will only allow me to send 5 invoices 😅. The next tier is £30 bit of a joke. Apart from that the app is good enough
  11. [R18] Invoice2go 3/5 · GB Great app….BUT….very disappointed: Bought this app going back about 10 years probably. Anyway, when I bought it, it was a one off payment for the premium features which honestly made my life so much easier, HOWEVER, few years later had to change the phone and while the phone (iPhone) automatically loaded the app back in the app was unusable and was now asking for a yearly subscription which put me
  12. [R7] Invoice2go 1/5 · US Deactivate My Account: I had to verify a couple of items and supposedly this email that was sent to me and never was said that my account was deactivated. This kind of confuse me and I had to contact customer support. They said they were gonna send me emails and never did so this app is garbage they lie to you. They don’t help you in any way and then there’s no information of what happened why it
  13. [R9] Invoice2go 3/5 · US Job: The reason I’m giving it three stars is because it says all the time you’re off-line and doesn’t necessarily come up with an estimate number and I’ve called and complained, but nobody’s responded.
  14. [R61] Billdu 1/5 · US Disappearing names: My invoices are losing customer names and costing me money and time . When I tried to get customer service assistance the chat keeps crashing the app . Will be looking into alternative options moving forward. Keeps asking for a review when I'm in the middle of invoicing. After my subscription is up I'd rather do it by hand .
  15. [R63] Billdu 3/5 · US Names on invoices keep disappearing: Names on invoices keep disappearing

  17. [R67] Billdu 1/5 · US Glitches: Will not save client names,looses estimates.
  18. [R37] Invoice2go 1/5 · US They got greedy.: I used this service since 2016 and will never recommend them after the way they treated loyal customers. They just kept going up on their prices and lowering features for forced you to open a bank account with some random bank. Anything else is better than this
  19. [R66] Billdu 3/5 · US Great app, but little pricey: I like the app but it is a bit expensive and has some minor issues, but makes onsite billing easy.
  20. [R75] Billdu 3/5 · US Pequeñas deficiencias: Por veces no me carga el link de la app cuando tengo que enviarlos por correo oh mensaje de texto y dan muy pocos clientes por la suscripción
  21. [R82] Billdu 1/5 · US Save your money: I was a subscriber since 2019 and loved it for the first couple of years, but around 2025 things started going downhill. Like any company, they got super greedy, prices jumped to nearly $30 a month, features that used to be included were pulled out and turned into separate paid apps, and the value just wasn’t there anymore. On top of that, customer support became painfully slow, i
  22. [R87] Billdu 3/5 · GB Greedy: I’ve had this app for a while now only lets you have 30 clients a year, for over £100 a year😠 won’t be with them next year.
