INVOICE PROCESSING
Route parsed Front invoices to the right Slack approver by amount
Parses an incoming Front vendor invoice and posts an interactive Slack approval card to the approver whose spending threshold matches the invoice total.
How it runs
The automated pipeline, trigger to output.
- TriggerVendor invoice email arrives in FrontFront
- ActionExtract vendor, number, and total with OpenAIOpenAI
- LogicSelect approver tier by invoice amount
- ActionPost interactive approval card to Slack approverSlack
- OutputLog decision back to Front conversationFront
What it does
Reads a vendor invoice that arrived in Front, parses the total and vendor, then decides who must approve it based on dollar thresholds and posts an actionable Slack card to that person. Small invoices go to a team lead; large ones escalate to finance leadership.
When to use it
Use it when approval authority depends on invoice size and you want the right manager pinged automatically instead of an email chain figuring out who signs off. Ideal for teams enforcing a delegation-of-authority matrix.
How it works
- 1A vendor invoice email lands in the Front inbox and triggers the flow.
- 2OpenAI extracts the vendor name, invoice number, and total amount from the body and attachment.
- 3A logic step compares the total against approval tiers (for example under 1k, 1k-10k, over 10k) and selects the matching approver channel.
- 4The flow posts a Slack message with Approve and Reject buttons and the invoice summary to the chosen approver.
- 5The approver's decision is captured and threaded back into the original Front conversation as an internal comment.
