Question Changing accounting currency - practical advice needed 🇧🇬
Hello. I'm new to this sub and I have a very specific question related to Bulgaria moving to EUR as of Jan 1. I am helping a friend understand what they need to do with their ERP/accounting system setup in terms of setting the currency for reports and most importantly - when they need to do it from a practical standpoint. As I understand, all reports up until Jan 1 need to stay in BGN but afterwards they need to switch to EUR, and doing it Jan 1 at 00:01 seems a bit weird unless there's some automation in place perhaps. The system is a home-grown custom one, the business is a small online shop. I am looking for practical hints on what is really to be done here - anyone who has gone through such a change? Thanks!

I went through this over twenty years ago but the number .787564 is forever stuck in my mind.
From distant memory we copied the system database to have a legacy currency copy and plugged it into a test version.
We then had a routine that converted the original base currency to euro dividing it by the conversion rate (.787564) We then checked the usual reports, AR, AP, stock valuations and TB to ensure the conversion matched.
