Dear  Ray Carnes (ray), these vendors price list can´t be used to calculate any quotation or product sales price list. When you make a quote or invoice this vendors prices you pointed are useless, please correct me if I´m wrong. In fact if cost and sale prices or sales price list could calculated using formulas from the vendors price lists it will be great, but didn´t found it yet the way. 

Vendor Pricelists in Odoo support any Currency that has been activated. 

Hi,

You’re facing a common challenge in Argentina due to volatile exchange rates: your company imports products in USD or EUR, sells local products and services in ARS, and wants to quote in ARS while keeping supplier costs in their original currency. Odoo’s standard behavior stores product cost and sale price only in the company’s currency (ARS in your case), so imported supplier prices are immediately converted and fixed, making it hard to adjust for daily exchange fluctuations.

A practical approach is to use multi-currency price lists for sales, though Odoo does not natively store product costs in multiple currencies. You can solve this by creating a custom field for supplier price in the original currency and using price list formulas or automated actions to dynamically convert it to ARS based on an updated exchange rate.

Alternatively, third-party apps or custom modules can provide multi-currency costing, automatically update exchange rates, and calculate ARS prices in quotations and invoices. The key is to keep supplier prices in their original currency and compute ARS sale prices dynamically, allowing quotations, invoices, and reports to reflect current rates without manual recalculation.

Hope it helps
