How it runs

The automated pipeline, trigger to output.

  • ActionFetch matching invoice records from AirtableAirtableAirtable
  • LogicCompute billed vs. expected amount delta
  • LogicFilter lines exceeding tolerance threshold
  • OutputAlert AP team in Microsoft TeamsMicrosoft Teams

What it does

For vendors or AP portals that POST statement data directly, this validates billed amounts in real time. It receives the statement payload, matches each invoice number to your Airtable invoice register, and computes the dollar delta. Any line whose difference exceeds a configurable tolerance is flagged immediately and pushed to the AP team in Microsoft Teams with the expected vs. billed figures, so overcharges are caught before payment runs.

When to use it

Use this when a vendor system or middleware can call a webhook and you want amount disputes caught instantly rather than at month-end. The tolerance lets you ignore rounding noise while catching real overbilling.

How it works

  1. 1An inbound webhook delivers the structured statement payload.
  2. 2For each invoice number, the matching record is fetched from Airtable.
  3. 3A logic step computes billed-minus-expected for every line.
  4. 4Lines exceeding the tolerance threshold are filtered through.
  5. 5A Teams message is posted listing each mismatched invoice with expected and billed amounts.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HTTP webhookTrigger any URL on agent actions.
  2. 2
    Connect AirtableBases, tables, views, automations.
  3. 3
    Connect Microsoft TeamsChannels, chats, files.
  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.
