As an European SAAS business selling via Stripe, there are a lot of things involved with VAT. This used to be a a time consuming, excel driven exercise. BUT no more since we switched to Quaderno. Everything we need for our tax forms is 1-click easy.

Nothing important. One smaller thing that would be nice is to have is more date range options in reports/sales. Simply so that we can see YTD sales info too, as it's now limited to 3 months max. And Markdown support in invoice items would also be more user friendly than HTML I think.

As we started approaching thresholds for various regions around the world our SAAS needed a way to calculate the taxes for each region and track them. We looked at some other tools but many of them were only targeted to one country. Quaderno let's use calculate EU and US taxes and other regions and tells us as we're approaching thresholds in each country which is great.

- Simple tax calculation - Somewhat easy to integrate API if you're a developer as there is pretty good documentation - Priced for SAAS businesses

As a developer I didn't totally understand the whole tax VAT collection process going into it. More guides on that would have been helpful as I was getting started. I'm a small business owner and software engineer so more guides on how to not only integrate it but also how to use Quaderno to calculate how much to report and where to report. Furthermore, if Quaderno offered paid phone/screen share support for making sure I had everything setup correctly I would have paid for that in an instant. I would pay by the hour for that kind of help and especially with filing my first tax reports. For example, one problem I learned about later was that I wasn't collecting the IP addresses properly at first in a way Quaderno could understand. So that was a whole headache.

Customer support was awfully not understanding. Business seems to have no idea that giving a discounter for a one-time fee is worth more than losing a subscriber.

Easy to setup with Stripe and Paypal, good info about taxes around the world

Price is just insane. $500 for 5000 transactions. When we have a business doing small transactions but with volume ($5 to $10), it is just insane as we will pay 1 to 2% of our income just for this service. And it is not even the subscription yet!

It was good will recommend other's to use it so they can also take advantage of this.

- Best thing was it was easy to integrate with project, - provide wide(different) payment Integration - The Technical support was good always helpful whenever I ask for help.- The best part of it is Invoice we can modify as per our requirement and it hold all the necessary data required.- It provide Quaderno Sandbox which is very helpful for testing and development

lack of documentation as well awareness around dev's .(as this can be very helpful when we have to integrate more than one payment integration)

If we want to integrate more than 2 payment service like stripe, PayPal and many more. then quaderno is helps to manage by their side we don't need to do anything. just we need to connect the accounts to the quaderno. also we can made many products as we want for different country.

the documentation for the APIs, specially for the Node Js. it will really helpful if they give the examples with APIs.
