Itemising tax on POS receipts

[Iain Fogg <ia...@westnet.com.au>]

Hi all,

I'm trying to work out how to display tax-inclusive prices on receipts 
generated by the POS application.

The standard receipt template works fine for showing the tax-exclusive 
price (basePrice) of the order items, the total sales tax for the order, 
and the grand total, but I'm having a bit of a hard time working out how 
to show tax-inclusive prices for individual line items.

I'm guessing I need to modify PosTransaction.java in the the POS 
application to add something like "itemTax" to the itemInfo HashMap, and 
would then be able to reference this new tag in the receipt template. 
The general gist would be to do something like:

    itemInfo.put("itemTax", 
UtilFormatOut.formatPrice(item.someFunctionToCallToCalcItemTax());

but it isn't clear what fn to call to calculate the item tax. This ought 
to be trivial but I'm not familiar enough with the API....

Any tips?

Cheers, Iain

Jacques,

Merci!

It seemed that while all the info I need is in the cart, the SVN POS 
simply wasn't revealing all. This is fine outside a VAT/GST environment 
I suspect, but in my case I need to store all my product data ex-GST so 
I can leverage all the VAT code to make sure my government gets its 
share of my sales :-( However, I need to do things like print receipts 
with GST-inclusive prices.

The nett effect is that I made a couple of small mods to the POS 
application to allow access to the sales tax adjustments that are buried 
in the cart's ship groups. I then exposed this info to the POS receipt 
printing routines and voila.

I'll try to post a JIRA and a patch soon, but I have a hard deadline for 
a shop opening next month and I gotta focus on that :-)

Cheers, Iain

Hi Iain,

Quick answer : I think that you should look at TaxAuthorityServices.java near line 105. Not sure it's enough but I guess usefull.
