Assign custom tax variable value permanently

[elkato]

Based on topic above, I'm trying to handle tax values on my own (different in my country) by permanently change value to array? From adding a product to cart or order,and maintain the value to the end of the process. Invoice with that tax too.

Is it possible to set that way with Price Formatter ? How and where should I use that?

Is there a better way to get that?

Thanks for doing great community!

I suspect that you should direct your attention towards the shopping cart and/or invoicing hooks rather than price formatter.... you might need to use PF down the road, but what you're thinking of doing could end up a lot more complicated than just formatting an amount in the cart.

Thanks for your reply brian!

I understand what you mean about PF.

So if I understand correctly to get a complete handle of taxes on my own (plan to  use 2 taxes levels, but switched by customer condition, not country), is not possible to change tax value on var permanently to be then generated with that value on invoice right? So I just could change output to screen on each page and then After invoice generated change on db on invoice...

Would be that right approach?

Thank you

before doing anything else, my first thought would be to check whether there was an existing solution in Marketplace (or elsewhere) that can do what you want.

after the invoice is created, but before it's sent to the client.

Thanks brian! for the info.

There is no addon for this. They have some tax manipulation for other countries.

I will take a look on that approach.

Argentina it is.

I'm seeing probably I will need to charge more taxes then. So I'm trying to figure out how I could handle this.

Taxes are based by products and conditionally by customer type. So it is possible to invoice item with different taxes, and possible 3 or 4 taxrates (3,5%, 10,5%, 21% and 27%).

So I think, I would need an addon module to handle product own taxes, adding then different new taxesrates columns to tblinvoices, or maybe better on a new referenced table for upgrade purposes, and lot of hooks to calculate taxes/subtotal/totals and calling api to modify invoice before email sent...

I hope some day to see that finished and working :/

I wouldn't recommend adding new columns to default tables - it would be easier to create a new table and reference one from the other.

I guess you might need to specify in the product, e.g with the use of a product custom field, which tax rate should be applied to that product..

i'd suggest having a word with @Kian about this as he wrote the Billing Extension addon and knows the WHMCS tax/invoicing inside out.
