How to calculate average days to return delivery using Frate Returns data
With Parabola, you can deepen visibility into your Frate Returns data—going beyond what's available with native analytics. One common questions customers ask is, "How long does it take for a return to actually be delivered after the return is initiated?" To answer this question normally, you'd need to export a CSV file every time you're reminded of this question and manually build the report in Excel.
Using Parabola's Frate integration, you can build a workflow that pulls live data from Frate and calculates this metric in real-time—alerting you via Slack, email, or Teams any time the number surpasses a custom threshold. Create custom filtering logic, calculations, and dashboards to improve your visibility and do more with Frate data, without waiting on engineering resources or relying on spreadsheets.

Why Parabola
“Before Parabola, I was spending at least four hours every Monday and Tuesday just pulling and cleaning PO and OTIF data from multiple sources. Now all of that is done Monday morning when I come in and I can spend my time auditing and reporting.”
What is average return delivery time?
Average days to return delivery is a metric that measures the number of days between when a return is initiated and when it is marked as delivered back to your warehouse. This helps track reverse logistics performance, manage customer expectations, and flag outliers or carrier performance issues.
