Exchange Rates and Equivalents — the Central Bank rate and an invoice in another currency

• TCMB rates on their ownThe bulletin is checked every 30 minutes; missed days come from the archive.
• For every companyA lira, dollar or euro company; cross rates go through the lira.
• Equivalent columnsUntaxed, tax, total, amount due and rate in the chosen currency.
• Never touches the documentThe invoice, its rate and its entries stay as they are.

Two parts: Exchange Rates brings the official rates and Currency Equivalents shows amounts in another currency.

TCMB Rates

• The bulletin the Central Bank publishes on business days is checked every 30 minutes and stored for each company and each active currency.
• The default rate is forex buying (as Turkish tax law values foreign currency). Forex selling or banknote rates are a configuration parameter.
• Missed days are filled in from the TCMB archive. The rate history opens as a line chart per currency, a list and a pivot.
• The navbar shows the official rates and the policy rate. Market indications (crosses, gold, Brent) are kept apart; nothing is booked with them.

Equivalents

• Lists of invoices, bills, journal entries and journal items have a currency switcher next to the pager. The choice is the user's own and is also in My Preferences.
• The invoice form shows one row per offered currency under the totals, with the rate and the rate date used.
• The rate is the official one for the invoice date. When there is none, the amount is left empty and marked, never converted one to one.
• Settings › Accounting › Currencies picks which currencies each company offers.
