Month-End Multi-Currency AP Rollup with FX Variance to Airtable
On a monthly schedule, aggregates all booked foreign invoices from Postgres, recomputes base-currency totals at month-end rates.

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

- 1Connect PostgresAny Postgres URL — query, write, migrate.
- 2Connect HTTP webhookTrigger any URL on agent actions.
- 3Connect AirtableBases, tables, views, automations.
- 4Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
- 5Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
- 6Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
More Invoice Processing workflows
Catch duplicate invoices as they hit your AP inbox
Watches your accounts-payable Gmail inbox for incoming invoice emails, fingerprints each one, and routes likely duplicates to a review label instead of into the approval queue.
Gate invoice approvals on a duplicate cross-check
When an approver clicks Approve in your AP system, a webhook re-validates the invoice against paid history in Postgres and Stripe charges.
Nightly audit that flags duplicate payments already made
Runs every night to scan the last 90 days of Stripe payments against your Postgres invoice ledger.
Block duplicate Stripe payouts before they send
When a new vendor invoice is queued for payment in Stripe, cross-check it against your paid-invoice history in Postgres and halt any payout that matches an already-paid invoice.
Agent that codes Front invoices to GL accounts and drafts a bill
An agent reads each Front vendor invoice, assigns GL account codes per line item using your chart of accounts and past coding history.
Detect duplicate Front invoices and archive originals to S3
Parses each Front vendor invoice, checks it against a history table for duplicates, archives the source PDF to S3 with a normalized key, and alerts AP when a duplicate is caught.
Run it inside a business
This workflow drops into a full company template. Import the org, and this is one of the playbooks its agents run.
