I’d like to automate the generation of invoices from my billing system. I can’t get the invoice tax drop down to populate from the URL query string. E.g. using
I’m using tax = 2 as 2 is the id for “VAT” in my database – see si_tax table in attached image. I’ve tried other ids and dropped the ] indexing (for total style invoice) but nothing works, the tax drop down is always blank. Any ideas? ………
Just noticed that quantity does not work either i.e. “&quantity=5” does not cause the first field quantity to be 5.
Also we use mostly the total style invoice (not a list of items). So I’m not sure how tax will work with respect to the tax indexes when there is no list of items? ? Also How would I insert the “gross” value for a total style invoice. I guess I could use an itemised invoice with just one item if I had to.
