The prompt

I want to forecast parcel spend across our carrier mix. Can you build me a flow that pulls historical invoice data from DHL, FedEx, and UPS, breaks down spend trends by carrier and service level, and projects a forward-looking forecast from that history?

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

What Parabola builds

A workflow with six steps you can edit:

1. Pull invoice history. API connections to DHL, FedEx, UPS, and any regional carriers. The flow ingests the line-level invoice data, not just the summary totals.

2. Standardize the line item. Service level, zone, weight band, surcharge type. Each carrier names these differently. The flow maps them into one consistent shape.

3. Build the trend. Spend by carrier, service level, and channel over the last twelve months. Weekly or monthly grain, whichever fits the planning cycle.

4. Project the forecast. Apply the trend plus seasonality plus any known volume changes from the sales forecast. Output the projected spend by carrier and service level.

5. Compare scenarios. Hold the current mix, shift volume to a different carrier, layer in a rate increase. The flow shows the spend delta for each scenario.

6. Output the report. Forecast file for finance, scenario comparison for supply chain, optional alert when actuals drift beyond the variance threshold.

Why teams stop doing this manually

Parcel spend lives in invoice PDFs and carrier portals. Each carrier formats the data its own way. DHL surcharges land under one name. FedEx calls the same thing something else. UPS exports a flat file with different columns each quarter. A finance analyst can stitch this together for a one-time look. Doing it every month, with confidence, takes a different setup.

The cost of getting the forecast wrong is operational. Underestimate parcel spend and the budget breaks in Q4 when peak hits. Overestimate it and the carrier mix gets locked in too early, killing leverage for the next negotiation. Both errors are common because the data is hard, not because the team is bad at math.

The work is precise and repeatable. Pull, standardize, trend, project. That is exactly the kind of work that lives in a flow. The forecast refreshes when invoices update. The scenarios run on demand. Finance and supply chain talk about the same number.

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 carrier mix, your service levels, and the planning grain you need.

Step 2. Connect your data.

API connections to DHL, FedEx, UPS, and any regional carriers. Plus the sales forecast and rate card if you want layered scenarios.

Step 3. Run it every period.

Monthly is standard. Weekly during peak. The forecast refreshes against the latest invoice data. Scenarios run on demand when finance asks.

FAQ

How far out can the forecast project?

Standard is rolling 13 weeks for ops and quarterly out four quarters for finance. Both run off the same source data. The grain is configurable in the flow.

How does the flow handle peak season seasonality?

The trend method can blend a 12-month rolling baseline with year-over-year seasonality. Q4 peaks get factored in based on the prior year's volume curve, then adjusted for the current sales forecast.

Can the flow model a carrier rate change before it lands?

Yes. Layer in the new rate card as a scenario input. The forecast recalculates spend under the proposed rates so finance can see the impact before signing the contract.

What if our carrier mix changes mid-year?

Add the new carrier as a source. The flow re-baselines the trend and the forecast refreshes. Historical volume shifts get tagged so the trend math does not break.

How is this different from the forecast view inside a carrier portal?

Carrier portals show their own spend. This flow consolidates every carrier into one view, plus your sales forecast, plus the rate card. The forecast reflects your full parcel program, not one carrier at a time.
