Excellent and quick

We do about 10 sales a week outside of our normal online shopping portal. We used to have to generate an excel quote, convert to invoice, track emails, paper... makes my head hurt just writing it. I looked everywhere for an easy to use, streamlined process that didn't require a huge CRM package with bloated costs for things we did not need. Did we really want a $25/month subscription to use a product that needed a 3rd party product like Zapier to kind of integrate into our squarespace account? No. We wanted something SIMPLE. This was it. Simple Quote, Simple Invoice. I was skeptical at first mainly because it was so simple, asked a ton of user data storage questions to ease my fears which were answered by support as soon as I asked them. We easily blew past the 3 free invoice and had no problem signing up. My few issues: We already had a stripe account but there was not a way to use it so now we have 2. Would be great if there was a shipping cost field on estimates/invoices. Would also be great if there were separate ship to/bill to fields. Other than that, we are super super happy with ease of use, streamlined process and the fact we get notified of the quotes being viewed is a huge bonus. Have the app and mainly use the web but makes it very easy to go from request to quote to invoice all in one portal with no paper being wasted or cluttering my desk. Fantastic web-service.

Used To Be An Amazing & Not Happy With The New Layout At All

We are updating our previous review seen below in quotes, because the developers have completely changed the entire layout. We loved the older version that we had come to know and trust last year. We are seasonal employees, so we had not noticed the changes until we came back to work today, May 25, 2020. We are completely lost with the new layout, if we can’t get used to this new layout we will unfortunately be canceling our paid subscription and look elsewhere. Why do developers have to take a good thing and change it? It was sooooooo much easier to use this app before they changed everything about it. We are so disappointed in this app now.

“Original review, We are independent contractors, & this app has saved us, so many times. We were even able to add our own logo in this app, which is a very nice feature. If we use the online version which had already spoiled us before we decided to purchase the monthly version, it still syncs with the app upon refreshing the app. We absolutely love this app”

Developer Response ,

Hi Camphosts, sorry about this, yes we have overhauled the app, and its definitely changed. However, I'm quite confident you'll get used to it in no time, and will be able to do everything you could do before just as quickly and easily. We're continuing to improve it ongoing. Unfortunately our app got to a place where we were struggling to maintain it, so we made the tough decision to overhaul it.

I hope you are able to get back up and running asap, our support team is always available 24x7 within the app in case they can help at all.

Thanks! Alex

Write Contracting Group ,


I’m a licensed general contractor and I hate invoices I am ADHD and LAZ why. Had them both since I was born. I’ll reason I became a contractor is because I didn’t want to go to work LOL anyway, I’ve tried every which way to cough up an invoice since that is what I have to do to get paidUntil we find a simpler way. Simple voice is the best when it comes to using a free app with no charges no hidden fees and unbelievable nothing to it no directions needed invoice making. In fact I’ve never wrote a review on any thing I’ve ever bought even if I really loved it. I guess I’m writing this review because I’m thankful. In a world where everybody’s lying cheating and stealing from each other like it’s normal because no one gets in troubleNo one takes responsibility for their actions and everybody can hide slowly but surely behind the big black wall of privacy given to them by do you know who… I’m thankful that somebody made something for me I don’t know who you are but thank youEverybody sees this review that needs to make an invoice and use this one.
