Clean, simple app but very basic for the cost. Can't search by customer, can't view invoice "balance due" in the main view if a partial payment was applied (must fully open each invoice)
Status indicator for "partial" payment exists however gets overridden with the "due" status leaving you to have to open every past due invoice to see if a partial payment was made. If a customer calls to question account balance you will find yourself opening each invoice and calculating their account balance in excel. A simple filter by customer and display balance due of each invoice is priceless and could be screen captured as a quick "account statement" if Sufio made a couple changes to their view/filter. Today this has to be manually created in an email or excel.
These are simply features to implement. Not many viewing/sorting improvements seen in almost 2yrs.
Software by subscription should come with continuous improvements....not here ***in response to the Sufio reply below.....the "partial paid" status only functions until the invoice becomes "due". At that point that tag/status is lost and each invoice must be opened to check the actual status.***

I used this app to download my invoices for my Program and at first my invoices were i English instead of German. So i talked to the support and they have ruled it in less than 5 Minutes! I can fully recommend Sufio!

I needed an invoice generator and Sufio became useful to me. Very fast and responsive support team resolved the issue within a couple of hours. In particular, the convenient invoice editing system works great right in the program interface! I am satisfied and recommend this app!

Fantastic, easy to use app full of features to make stunning invoices. The best part however is the wonderful customer service. Djimi went way above and beyond what I ever hope for from a customer service point of view. Responded to my emails and request for customisation in a fast and friendly manner. I would recommend this app to anyone wanting more than just an invoice app. This is the full package.

We highly recommend this application because of its great performance and excellent support on installing and customizing the application to your specific needs. Especially when you have a B2B web shop like ourselves, it is an easy way to capture customer's VAT number and apply the correct VAT rates.

We did our share of research to find an invoicing app that both complied with our accounting requirements and allowed us to customize invoices in a way that reflects the brand.
Luckily we found Sufio! The product is amazingly simple and reliable, and so is their customer support. When we needed help to implement a small but vital change, their team was extremely responsive and they made the whole experience equally fun and effective. Kudos to Djimi and the entire Sufio team!

This app is really amazing! 5 Stars probably are not enough... They customer support is something incredible.. they are fast and reliable. I had a urgent issue and they solved it in minutes! It's just incredible. Thank you so much.

If you need a perfect app to create great invoices for your customers and to keep your accountability, this is THE ONE!

We are using Fusio for a short term, but we love the app until so far. We are using it to sent invoices to our customers and for a VAT check since we sell B2B and B2C.

We needed some help with the implementation of the VAT check and Michael from Fusio helped us perfectly. I can only say that we are really happy to far using Fusio and their support is amazing. Definitely an app to recommend.

Keep up the good work!

We are really satisfied with the Sufio app that generates invoices for our website sales. The invoice creation is seamless and problem-free, the support is very fast and professional, they even added the Bulgarian language for us.

Fast and effective ! Also the developers are very responsive and help you for special requests ! perfect ! thanks guys
