Simple Invoice ‑ Order Printer

This Invoice app is exactly what we were looking for. Unlike other free versions, this one covers all bases and is customizable. The support is also 5 stars in my book. Considering this is a free app, to have such a high standard of support is amazing. Shout out to Chuck!

Not only is this is great design template (minimal and easy to comprehend), it is super helpful for startups like ours that it is fully functional even though it is a free app.

Moreover, Chuck personally helped solve a few customisations that made it easy to use with our specific tax regulations (something most off the shelf apps aren't able to provide)

I wholly recommend using Simplio.

Support is incredibly fast and helpful, app is easy to set up and use. Very happy with it and 100% recommend.

Fully editable invoices template, great for other languages too. Awesome customer support too. Totally recommended!

I love your product. It si vert simple to use ans Invoice are good looking
It would be great to be able to print directly to an iPad or iPhone.

Now this app REALLY help me. It integrates smoothly into shopify, makes invoicing a one click affair. The layout of the invoice is fine, easy to download and send. It is also free, but it is something I would be willing to pay 2-3$ per months (not 10-15, my impression that most of the apps on shopify app market is extremely overpriced).

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

I am delighted with the application. It has a convenient and intuitive interface and quickly generates neat PDF invoices. Support responds promptly, and updates are released regularly. An excellent tool for issuing invoices efficiently.

The team also helped with template customization very quickly, which was critically important for my business.

Outstanding support & clean invoices – highly recommended!

The interface is clean, intuitive, and the invoices look professional from the start. But what makes it exceptional is the team behind it.

You can tell this isn’t a faceless corporation – it’s a small, passionate team that genuinely cares. I reached out with a special request, and not only did they respond quickly, they actually built a custom solution for me.
That kind of support is rare these days.

If you’re looking for a reliable invoice app with top-notch service and real people behind the code – this is it.

We have not been using Simplio's app for very long but at every step of the way the app has performed over and above our expectations.
In addition, when throwing a curved ball at Robert or Chuck, they have risen to the challenge and enhanced the capability for our immediate benefit, swiftly and exactly as required.
We cannot praise them enough. Keep going!
We'll be back for more and hope to be able to roll out to more stores. Bravo.
