The prompt

I want to digitize commercial invoices and packing lists from email PDF attachments and validate them against PO records in Excel. Can you build me a flow that extracts line-item quantities and declared values from the PDFs, joins them to the corresponding PO by line number, flags any quantity or value mismatches, and surfaces discrepancies that would create customs exposure?

Just copy and paste the prompt into a new Parabola flow to get started.

What Parabola builds

A workflow with seven steps you can edit:

1. Monitor the inbox. The flow watches the shared customs inbox for new CIPL emails. PDFs and Excel attachments get picked up automatically.

2. Extract line items from the PDF. Item description, declared quantity, declared value, country of origin, HTS code if it's on the document. The AI step handles the layout variation between suppliers.

3. Pull the PO from the reference file. Whether it lives in Excel, a shared drive, or your ERP. The flow grabs the open POs for the supplier and stages them for the match.

4. Match line by line. Same PO, same line, same item. Quantity, unit value, and total each get their own comparison.

5. Flag the mismatches. Quantity over the PO. Value above the declared rate. Missing HTS. Wrong country of origin. Each exception gets a reason code so the broker knows what to fix.

6. Output the validated file. Two views. The clean version of the CIPL for the broker to file against, and the exception report for the team to work before submission.

7. Send it where the team works. Customs Slack channel, customs email distribution, or an internal portal. Anything urgent surfaces before the entry gets submitted.

Why teams stop doing this manually

CIPLs come in every shape. A factory in Vietnam sends an Excel sheet with line items in three different layouts. A supplier in Italy emails a PDF that scans well one month and poorly the next. The freight forwarder gets a packing list that almost matches the commercial invoice, except for two SKUs that got substituted at the last minute. Customs needs all of it reconciled before the entry goes in.

The manual version is one person staring at three documents on three monitors. Read a line off the PDF. Look up the PO line in the spreadsheet. Compare the quantity, compare the value, type the variance into the audit sheet, move to the next line. A 30-line CIPL is forty minutes. A 300-line entry summary is half a day. And if a line slips, the entry filing carries the wrong number into customs.

The cost of skipping the validation is regulatory. An undervalued declaration creates a duty shortfall the broker has to disclose. An overdeclared one ties up working capital. A missing HTS code stalls the entry at the port. Every one of these traces back to a line the customs team didn't have time to catch.

How it works

Step 1. Paste the prompt.

Open Parabola, paste the prompt in section 2, and let it ask follow-up questions about your supplier mix, your PO format, and which fields are mandatory before the broker files.

Step 2. Connect your data.

Inbox for the inbound CIPLs, file location for the PO records, ERP if the PO lives there. Add any rate-card or HTS reference tables the validation needs.

Step 3. Run it every shipment.

The flow triggers on a new email arrival, parses the attachments, runs the match, and posts the exception report. The customs team works from the flagged list, not from raw PDFs.

FAQ

Does this work for any supplier's CIPL format?

Yes. The AI extraction step is layout-agnostic and learns each supplier's format from a handful of examples. Add a new supplier and the flow handles it on the next inbound.

What happens when a line on the CIPL doesn't exist on the PO?

The flow flags it as a missing-PO exception with a reason code. The customs team can resolve it, request a corrected document from the supplier, or skip the line.

Can the flow handle scanned PDFs and image-based attachments?

Yes. The AI extraction handles OCR on scanned documents. Image quality matters, so suppliers sending poor scans will need to send better originals, but the flow extracts what it can.

What if the PO is in a different system every quarter?

Repoint the source step. The match logic and exception rules don't change. The flow works against whichever system owns the PO of record.

How is this different from a customs broker's portal?

Most broker portals tell you what got filed, not what should have been filed. This flow catches the discrepancy before the entry submission, which is the only place a broker can fix the data without an amendment.
