"A partner that grows with us"
4.5/5
What do you like best about Fonoa?

What I value most about Fonoa is the combination of strong people and breadth of capability. Tavo and Zori are fantastic. They make it very easy to get in touch with any question or idea, and it consistently feels like they have my best interests at heart. They are never salesy for the sake of it, but they always take the time to explain how Fonoa can support what we are trying to do. Best of all, they treat the relationship as a genuine partnership on scoping and roadmap rather than simply selling a fixed product. When I raise a new use case or a possible new way for Fonoa to help, the response is collaborative and thoughtful, and that has made a real difference to how we plan and prioritise our work together.

That partnership is backed by both breadth and depth. I rely on Fonoa across a wide range of workstreams, from tax determination through to e-invoicing across multiple jurisdictions, and having that covered by a single partner rather than a patchwork of point solutions is a significant advantage. It also means the team understands how the different pieces of our indirect tax landscape connect.

I have also been impressed by how seriously the team engages with genuinely complex indirect tax scenarios. Our use cases are rarely simple, and rather than pushing back or oversimplifying, the team works through the detail with us to find workable solutions. That willingness to engage with the hard edge cases is exactly what you need from a tax technology partner. Review collected by and hosted on G2.com.

What do you dislike about Fonoa?

The main area I would like to see develop is the pace at which new features and jurisdiction coverage are delivered. The team is always receptive when we raise a new requirement, and the appetite to help is clearly there, but the turnaround from raising something to seeing it delivered can be longer than we would ideally like. Given how quickly the indirect tax and e-invoicing landscape is changing, faster delivery here would make a strong offering even stronger. Review collected by and hosted on G2.com.

"Flawless Workflow and Fast Performance Once Data Is Uploaded"
4/5
What do you like best about Fonoa?

I really like the user interface, its response time once the data is uploaded and the workflow system works flawlessly which has saved many hours of our time in reviewing the returns. Review collected by and hosted on G2.com.

What do you dislike about Fonoa?

The issues I have is at the data gathering stage. It takes approx 45min to sometime more than a hour long to upload the data. Further the formatting issues for example instead the software should allow both excel and csv uploads but currently it limits to csv only. Review collected by and hosted on G2.com.

"Gold-Tier Documentation and a True Partner Mindset"
4.5/5
What do you like best about Fonoa?

Gold tier documentation!

Amazing team members, varying from all levels (compliance, engineering, customer support).

Can-do attitude with wanting to solve problems, and role playing a team/partner rather than a vendor/customer relationship Review collected by and hosted on G2.com.

What do you dislike about Fonoa?

The only drawback would be, at least in the example of Singapore, giving realistic timelines would have helped manage internal expectations. I recognise this was largely due to external reasons, but promises made should account for all possibilities. This would ensure the partner relationship continues healthy, and there is little “overpromising” happening Review collected by and hosted on G2.com.

Broad, expanding country coverage for VAT and e-invoicing, and a responsive team when we hit edge cases or bugs on either side. Review collected by and hosted on G2.com.

What do you dislike about Fonoa?

Honestly not much to point to. If anything, just the usual lag as new country coverage gets built out over time. Review collected by and hosted on G2.com.

"Great partner for eCommerce tax validation"
4/5
What do you like best about Fonoa?

Fonoa is very easy to work with and brings a great deal of technical expertise. Support queries are handled promptly as well.

For a multinational business, having a knowledgeable partner who simplifies the implementation of both country-specific and cross-border tax validations is essential. Review collected by and hosted on G2.com.

What do you dislike about Fonoa?

I am not particularly satisfied with the pricing model, as I find it to be on the expensive side.

The cost for lookups that exceed the agreed contract volume is also quite high. Since this is a new implementation, accurately estimating the required volume can be challenging. Review collected by and hosted on G2.com.

"Fonoa delivers on compliance and transparency"
4.5/5
What do you like best about Fonoa?

Fonoa provides a strong layer of confidence when it comes to invoicing compliance and reporting obligations across multiple countries. It uses a single API, which is amazing for scaling to multiple countries.

One of the most valuable aspects is how it handles the connection to local tax authorities. This removes a huge operational and compliance burden from our internal teams. I also really appreciate the transparency it offers. We can easily track what has been reported, the reporting status, and view any potential issues that need attention.

The country-specific integration guides are particularly helpful. They save a lot of time by summarizing the key technical and legal requirements in a clear and accessible way.

Overall, Fonoa has made it significantly easier to scale operations into new markets without needing to build deep tax expertise in-house for each one. Review collected by and hosted on G2.com.

What do you dislike about Fonoa?

The biggest challenge with Fonoa is its pricing model.

While the product delivers clear value, especially in terms of compliance and automation, the cost can become quite high, particularly for businesses with growing transaction volumes, as pricing is tied to usage.

This makes it somewhat difficult to forecast costs, and it can become a limiting factor when planning large-scale rollouts or onboarding new countries.

That said, the product is solid overall, and we continue to rely on it for our most important compliance workflows. Review collected by and hosted on G2.com.

Response from Aubrey Harper of Fonoa

Karen, thanks for such a comprehensive review. It’s great to hear that Fonoa has helped reduce the burden on your internal teams while giving you visibility and confidence across markets. That’s exactly the kind of impact we hope to make.

We also appreciate your honest feedback on pricing. We understand that usage-based models can bring challenges when forecasting for growth, and that’s something we’re continuing to evaluate as we scale. Your input is incredibly valuable as we think about how to best support customers at every stage.

Glad to be part of your compliance journey, and looking forward to helping you expand into even more markets.
