We are very happy with Simplio Premium! We have many international shipments that need invoices. We converted from a manual invoice process, which was very time-consuming, to Simplio. Now, everything is automatic. The Simplio invoices, quotes, and packing slips look great out of the box, and most customization is easy. We also contacted support for some additional changes. They were very responsive and quickly addressed our specific needs. Highly recommend!

Transitioned from my own integration to Simplio a couple of weeks ago and its been very easy process. Configuration options are simple to understand and easy to implement. The new invoice process is quick and simple with professional documents that are essential for dealing with my B2B clients.

Best app for B2B shops who need to issue proper invoices for customer's accounting as well as for exporting/importing. The templates are easy to modify and if you need some minor changes, the support is quick and super responsive.

The best invoice I ever used This app has saved a lot of our operation time especially when we are processing more than 200 orders a day. , Highly recommended!

Estoy utilizando esta app en mi tienda y funciona perfectamente. El servicio de atención al cliente es muy rápido y son muy amables! Recomiendo.

Great support! Requests are handled really fast. So far this app covers all our needs regarding invoicing. Easy to use invoice editing and lots of features you would want to see in an app like that.

Nice and easy app. Perfect also for the small businesses. Fully customizable and great support team. Definitely suggest it!

This app is excellent choice for all invoicing needs. Support from Chuck is also very quick to answer and to resolve or help with any custom request. We decided to use Simplio not just for the all features than offers but because we could add custom-field and meta-fields to our invoices which for example we use to have a warehouse shelf location for picking our products. Recommended app.

Simple Invoice is a great add-on for Shopify. In our case we are going to start with a store from Spain and it fully meets the expectations that the invoice appears professional and meets legal requirements.
First I started for free to see how it worked. I liked it and go to the Pro subscription which is $ 6.99 but it is totally worth it. I work from Spain and I have adapted the way of entering the CIF or NIF both in the Shopify registry and in the pdf of the invoice. They responded promptly and professionally.
Fully recommended

This app has been brilliant! Required some slight changes to suit our needs, but support was super responsive and completed our request in no time. Will totally recommend :)
