Firstly, apologies, I realize this is an oft-repeated topic. I've read a number of threads, but am still confused.
Currently, my store at ZippBike.com has prices listed without tax, marked "is taxable" and the tax is added at checkout. Seems straightforward and elegant to me, but some customers are bitching about tax. So the bosses are asking if we can show the prices with tax, but still keep them broken out for accounting purposes.
I see in the Admin > Taxes area there is an option to "Show price with taxes included". But whne I check this, nothing happens. Prices shown remain the same.
Another thread suggested I have to change all my prices to include the 7% VAT for Thailand (we have no international or tax-exempt customers) and then check this box. But if I do that, are the taxes shown separately at checkout? And does my downloadable tax report still operate the same?
Other threads (all old) suggested I need a plugin app to achieve this.
How do I do it?
