Access Level 8 Lesson 4 touches on Sales tax. Likely doesn't apply to your situation, but maybe it does.  I think if it was me, I'd concentrate one currency first. Get everything to work and then tackle/convert the other one.

I handle #1 with a combobox. I use the same form and simply change the combobox value to match the situation. If someone asks for a quote, I prepare the invoice form and change the combo box value on the form to QUOTE. If they place the order, I simply open the invoice form and change the combo box value to INVOICE. The combo box also feeds the report so whatever is chosen on the form shows on the report. Your combobox will have 3 options: Cost Estimate, ProForma Invoice, Tax Invoice.

#2 can be an If Then or IIF statement in the underlying orders detail query (or in vba) for choosing prices based on a currency value in the customer file or on the invoice form.

Those are important legal documents that may have complex layouts and important legal fine prints.  You either have to manually recreate all of that detail in the Access report designer, or scan an actual blank document as a picture and use it as the background for the report, then add fields to it.  I believe Richard has a video on this very practice, but I don't remember where or when or what it's called.
