# Tax software helps you file. We file instead of you.

Compliance tools do real work. They determine the right rate, keep up with rule changes, and prepare returns you would otherwise assemble by hand. What none of them can do is change who owes the money: the registration is still in your name, the return is still your return, and the letter that follows an audit is still addressed to you. There is a second option, and it is worth understanding before you buy either.

The tax on each line has already been collected, and the return it belongs to is ours.

## The same six jobs, done two different ways

Working out the rate

An engine looks up the rate for the buyer's location and hands it back to your checkout to charge. Here the rate is applied by the party that will remit it, and it can be folded into the displayed price so the total does not move at the final step.

Holding the registration

Software cannot register for you. Someone has to file the application, hold the number and keep it in good standing. We hold ours — across the 27 EU member states, and wherever else a sale we make requires one.

Filing the return

A tax tool prepares a return that you or your accountant then sign. Under our registrations there is no return with your name on it to sign, because the sale was not made by your company.

Answering the authority

This is the job nobody prices properly when comparing tools. Questions about a filing go to the seller who is registered, so on these sales they come to us.

Business buyers and tax IDs

Company details and tax registration numbers are collected during checkout, which is the only moment a buyer reliably provides them, and the invoice that follows is issued by us as the seller. Which document a given buyer receives depends on whether they filled that step in.

The recurring case

Subscriptions keep charging into tax years that have not happened yet. Each renewal is priced against the rules in force on the day it charges rather than the day it was signed.

## How to work out which of the two you need

1.  01
    
    ### Ask who the seller is
    
    Everything else follows from this. If your company is the seller, tooling can make compliance efficient but cannot make it somebody else's. If we are the seller, the obligation is ours and the tooling question mostly stops existing.
    
2.  02
    
    ### Look at what you sell
    
    Digital goods and software are what this platform covers. Physical products bring shipping origin, destination rules and product-level taxability into the calculation, and that is a tax engine's territory rather than ours.
    
3.  03
    
    ### Count the jurisdictions you would have to enter
    
    One home market that your accountant already handles is a different problem from selling into a dozen countries from launch week. The second is where the liability moving is worth more than the arithmetic being automated.
    
4.  04
    
    ### Decide where you want the liability to sit
    
    That is a business decision rather than a software one, and it is the right one to settle before you evaluate either kind of product.
    

## When a dedicated tax engine is the better answer

01

### You sell physical goods

Shipping brings in origin-based rules, product classification and destination logic that a digital-goods platform does not model at all. If there is a warehouse in your business, buy the engine.

02

### You have to be the seller of record

Some businesses cannot hand that over: customers sign contracts with your company, procurement requires your name on the invoice, or the licence you grant is legally yours to grant. Then the obligation is yours by design, and the right move is to automate it properly rather than to look for a way out of it.

03

### You already carry registrations

If you are registered and filing today, changing who the seller is on new sales does not clear the past and does not automatically mean you can deregister. What you can and cannot unwind depends on facts we do not have — that one belongs to your accountant, and we will not pretend to answer it.

04

### Your sales run through several channels

Selling through your own site, a marketplace, resellers and an app store at once means several sets of rules to satisfy. A single engine sitting across all of them can fit better than moving one channel to a different model.

## What sellers say once they have switched

[★★★★★ 4.8/5 from 10 reviews on G2 →](https://www.g2.com/products/fungies-io/reviews)

 [Vadim Finayev Head of Growth, Leadsin.io

“We work with quite a few merchants of record, but none comes close to the support and speed of implementation of Fungies. If you want a payment partner that actually gives you the feeling they want to work with you — rather than leaving you on read for three days or randomly restricting your account — you are in the right place.”

“I researched the options and Fungies was the best fit for functionality and customisation within a store builder you can connect to your own domain. Taking a small percentage of sales, instead of charging a subscription for every environment and plugin, is refreshing.”

## Questions about tax tooling

### Is Fungies tax compliance software?

### So do I still need to register anywhere?

### Can I use a tax engine and an MoR at the same time?

### What happens to my income tax?

### Who deals with an audit?

## Buy the tool, or stop being the taxpayer

If your business has to be the seller, get a good tax engine and run it properly. If it does not, start selling through us and the returns stop carrying your name.
