At a glance
A 90-day sparkline of your average Sendle cost per parcel, so you can see the direction of travel at a glance rather than a single point-in-time figure. The line answers one question: is despatch getting cheaper or more expensive per parcel over the quarter? No alert fires on this card; it is a trend read, and the slope matters more than any single day.
What it tracks
For each day in the trailing 90 days the card divides total booked Sendle spend by parcel count, then plots the resulting cost-per-parcel as a sparkline read fromGET /api/orders. Because Sendle prices flat-rate-by-zone, the line moves for one of three reasons: your zone mix shifted (more regional or far-zone parcels lift the average), your parcel weight or size profile changed (heavier items move into a higher band), or a Sendle pricing or plan change took effect. A steady or gently falling line is the healthy state. A sustained upward slope is the signal to investigate the mix rather than to panic about a single day. Read this card alongside Avg Shipping Cost for the current-period figure the line is trending toward, Cost by Zone and Cost per Parcel by Zone (3 AU / 5 US) to attribute a rise to a specific zone, and High-Cost Shipment Outliers to see whether a small number of expensive parcels are dragging the average up. If the trend is rising, Sendle Premium Monthly Subscription ROI is worth checking, volume discounts may already be paying for themselves.
