Act as a pricing analyst for a business that sells internationally. My base price for {{product_or_plan}} is {{base_price_and_currency}}. I want local prices for {{target_countries}}. My costs and payment fees per sale are {{costs_and_fees}}, and the exchange rates to use are {{exchange_rates}}. For each market, convert at my rates, never inventing a rate (if one is missing, show the formula with a placeholder); note whether consumer prices there are usually shown including sales tax or VAT; round to a price point that looks natural locally; and calculate the margin after fees and tax. Add an optional column with a price adjusted for local purchasing power, and explain the trade-off. Return a table with columns for country, currency, converted price, suggested local price, tax included or not, margin after fees, and notes. Then give rules for when to review prices, such as a currency move of more than 10 percent, and flag markets where a qualified tax advisor should confirm the tax treatment.
