CRE Loaded UK VAT / TAX settings setup required + more

I have a UK based ecomms site running CRE Loaded 6.2 B2B, it's had quite a number of mods and addons added over the past two or three years, so much so I'd struggle to tell you them all, but what I've not decided we want it to do is do some VAT calculations for us, I'll give you what it does now then what I'd like it to do if that's good for you, I should just mention as well a lot of this is because we are a VAT registered business and looking to up scale the volume of sales, at the moment I don't bother running any tax rules at all, everything as far as CRE is concerned is classed as non-taxable and everything to the outside customer as including VAT at 17.5%, we don't provide VAT invoices as automated by CRE and we as most of our customers are not likely to be VAT registered this method sort of suits us, but as we are likely to take on more trade customers and as I have just purchased the vTiger - CRE Integration from Magnetic One I'd decided now is the time to also get the VAT thing sorted out on CRE, it may as well work it all out as it'll make things a lot nicer when importing customers from CRE to vTiger, I plan on using vTiger more and more for invoicing etc. where as at the moment we just use CRE and manually create a VAT invoice for any that do need it.... Ok I've waffled on a fair but now! Here is what CRE does now and what I'd like it to do: What is does now: Shows all prices to the end customer with no tax settings We have a note at the footer along the lines of... All prices include VAT at 17.5% blah blah.... No taxes are shown at checkout as there are none set What I'd like it to do: Show all prices to end customer including VAT in shop Possibly show prices both including and excluding VAT at the same time in main shop (not sure on this one?) Make sure VAT is added to both the main product and any product attributes (I'm struggling with this) At checkout show all prices including VAT inc. products, delivery, discount vouchers, anything. Make sure the vouchers don't complicate VAT, so if it's £10 off voucher that's £10 off the final price including VAT In the viewable invoice to the customer make this a genuine VAT invoice showing prices ex VAT, VAT amount, total amount Make sure all these VAT settings and anything else are passed to the payment processor which is either SagePay or PayPal Now I've probably missed some bits out above that I'll remember down the line, but for now that's the lot, I've had a look myself, I can sort of get the VAT thing working for EU countries, doesn't seem to work on product attributes though, also seem to recall I got rid of the inc. and ex. VAT things on the customer viewable invoice (the one you see in account history) as we'd decided not to use it at the time, so these need bringing back. I look forward to your bids!
