UPDATE: Our good friend Derek Allard (whose brainchild is said BambooInvoice) has informed me over at the BI Forums that an update is forthcoming which will include a much more versitile taxation system. /me wonders what other delicious treats will be bundled with this new incarnation... shall it even be 1.0 ??!
--==:[0000.0000]:==--
Not just for Canadians, but anyone who may want to use one, the other or both taxes on a single line item in Bamboo Invoice.
**WARNING** This hack is not for the faint of heart, I may have missed something in the chronicling of this adventure and I can't guarantee this will work for you in any way.
In case you haven't heard, BambooInvoice is only the slickest open source online invoicing system built with CodeIgnitor.
This mod is quite a hack, but the principal is to double the 'taxable' functionality for each line item, thus having a taxable1 and taxable2 for each item on the invoice.
To pull this off, modify the existing bamboo_invoice_items.taxable field to be called bamboo_invoice_items.taxable1 and add another field of INT(1) or BOOLEAN (if you will) called bamboo_invoice_items.taxable2
...Then make the following changes to the following files.
