When you first created your Business in Wave, you chose a currency. This is now your default Business Currency, and it cannot be changed.
This article explains why this restriction exists, and some options if you have created your Business with a different Business Currency than you intended.
How Business Currency is set
When you first register for Wave, your Country and Currency are detected, and these are used to create your first Business in Wave. You can choose a different Business Currency during initial account creation by clicking the Change this link.
For additional businesses that you create after your Wave account is active, you choose the Business Currency during the creation process:
Why can't Business Currency be changed?
There are two main reasons why Wave does not make it possible to change your Business Currency: firstly, it would be really hard to do; and secondly this should virtually never happen.
While some large multinational businesses operate their management accounting in one currency while reporting and filing tax in a different currency, virtually every small business — which is what Wave exists to serve — reports in the domestic currency of where it is located and pays tax. US businesses report in US Dollars; Canadian business report in Canadian Dollars; UK businesses report in British Pounds; and so on.
But what happens — you may be wondering — if you are running a small side business and relocate to a different country, where you will pay tax to a different taxing authority, in a different currency? The simple answer to this is that you are now running a different business!
It may feel the same. You may be coaching or consulting with the same clients as before, and using the same business name as before, but it is a different business. You have a 'Before-I-Moved' business, and an 'After-I-Moved' business, with obligations and dealings in two different jurisdictions.
What to do if you move your business to a new Country
As mentioned before, if you move your business to a new country (and assuming you are not trying to account for a large multi-national corporation on Wave!) then it is, in essence, a new business.
The Wave part of this is easy. Simply create a new Business: MyCo (New Country).
The accounting part - if you want to do this 100% correctly - is not so easy, and you are going to need the advice of TWO accountants: an accountant in the country you have moved from, to help you with the impacts of closing or transferring your business overseas; and an accountant in your new country to help with creating a new business and accounting for the value that you bring from your pre-existing business.
This would be a great time to click the 'Find an Accountant' link on the left navigation bar in Wave, and start asking some questions!
What to do if you simply set up your Wave business with the wrong Business Currency
If you have not moved at all, and simply chose the wrong currency when setting up your business, the only real option is to start a fresh Business with the correct Business Currency. The good news is that Wave makes it easy to maintain multiple businesses within your Wave account, so you can add your new Business and import the necessary data etc, while still having your old Business to refer back to. (When you have finished setting up your Business with the correct Business Currency, you can go back and archive the old one so as not avoid the risk of any confusion between them.)
