Newbie issues

Hi - I'm new to LiteCart, and impressed so far. My shop is working nicely: http://ktizo.co.uk/litecart/en/ but I have a few questions.

1) Is it possible to add a prefix to the order numbers? (e.g “Inv15#12” instead of “#12”)

2) On invoices, the subtotal does not include shipping. Can this be changed?
What I'd really like is:
Subtotal inc shipping
VAT
Total (Subtotal + VAT)
This woudl help with VAT returns.

3) Invoices do not show the customer’s VAT number. Can this be added if they supply it, or just blank if they don’t?

4) Can someone explain what ""priority"" means on lots of the setup menus? What is it for?

I'd appreciate any help!

Best regards,
Jon.

Welcome to LiteCart Jon! Glad to hear you had a positive experience so far.

1. If this is regarding the printable order copy I suggest you edit the view and simply add ""Inv"".

2. To display the shipping fee inside the subtotal you need to rewrite the module ot_subtotal.inc.php and disable ot_shipping_fee.inc.php.

3. This will be added in a future version because of VAT reverse charge in the EU. For now just output $order['customer']['tax_id] in views/printable_order_copy.inc.php.

4. Priority is the same as sort order or process order.
