What it does

At month close this flow summarizes every foreign-currency invoice booked during the period. It groups by currency, totals the original amounts, compares the rate booked at receipt against the month-end rate, and reports the FX variance per currency in a clean Airtable view finance can share.

When to use it

Use it when leadership wants a monthly picture of how much currency movement affected AP between invoice receipt and period close, broken out by currency, without a controller building it by hand each month.

How it works

  1. 1A monthly schedule trigger fires on the last business day of the month.
  2. 2A Postgres query pulls all foreign invoices booked in the period with their captured receipt rates and rate-dates.
  3. 3An HTTP call fetches month-end rates for each currency in the set.
  4. 4A logic step rolls up totals by currency and computes realized FX variance against the receipt rates.
  5. 5The per-currency rollup with variance is published to an Airtable reporting base for distribution.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect PostgresAny Postgres URL — query, write, migrate.
  2. 2
    Connect HTTP webhookTrigger any URL on agent actions.
  3. 3
    Connect AirtableBases, tables, views, automations.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
