Orders / Day, Mercari

Orders / Day for Mercari stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

Metrics type: Supporting Metrics • Category: Marketplace

At a glance

Orders / Day plots your daily order count over the last 30 days as a line. It reveals your selling rhythm, the weekday and weekend pattern, and the visible bump after a re-listing batch or a round of price drops.

What it counts	The number of orders placed each day across the trailing 30 days, drawn as a daily line chart.
Sample type	Backend API data from Mercari, refreshed on the standard data refresh.
Why it matters	Daily cadence tells you when buyers act and whether your interventions work. A flat or falling line is a prompt to re-list or adjust pricing; a spike confirms what is working.
Reading the value	Read the shape, not a single point. Look for the weekly rhythm, the baseline level, and any step-changes that line up with your actions.

Calculation

Vortex IQ counts completed orders for each calendar day across the trailing 30 days and plots them as a time series. Days with no orders are shown as zero rather than skipped, so the line keeps an even daily spacing. Because it is a daily count, the chart naturally exposes weekday-versus-weekend rhythm and any step-change that follows a re-listing batch, a price drop, or a Smart Pricing adjustment.

Worked example

A representative reading of Orders / Day for a typical Mercari reseller. Imagine a seller whose line hovers around 3 orders a day, climbs to 6 or 7 on Sundays, then jumps to 12 the day after a 40-item re-listing batch before settling back. That tells you two useful things: weekends are your strongest window, and re-listing produces a real, if short-lived, lift. The action is to time re-listing and price drops to land just before your strong days rather than spreading them thinly. There is no alert on this card, so use it as a diagnostic. Cross-reference mer_listings_in_freshness_boost to see whether the re-listing lift coincides with more stock in the boost window, and mer_total_revenue to confirm the orders carried value. Vortex Mind traces upstream causes behind a sustained dip, and Ask Viq answers plain-English questions like “which day this month sold the most orders?”

Sibling cards merchants should reference together

Card	Why merchants reach for it
mer_total_transactions	Totals the orders that the daily line breaks out.
mer_listings_in_freshness_boost	Links order bumps to fresh, boosted listings.
mer_total_revenue	Confirms whether busier days carried real value.
mer_aov	Shows whether order spikes came at the cost of lower value.
mer_orders_by_country	Adds the geographic dimension to daily volume.

Reconciling against Mercari

Where to look in Mercari’s own dashboard:

In the Mercari seller app, your sales history lists each order with its date. Counting orders per day there should match this chart, though Mercari shows them as a list rather than a daily line.

Why the Vortex IQ value may legitimately differ:

Reason	Direction	What to do
Period boundary. An order placed near midnight may fall on a different day depending on the cutoff used.	Variable	Match the period range.
Time zone. Order timestamps may be recorded in a different time zone, shifting an order between adjacent days.	Marginal	Confirm time zone match.
Filter scope. This card counts completed orders only, excluding cancelled or pending items.	Variable	Match filter settings.

Cross-connector reconciliation: If you compare daily cadence against another marketplace, align the day boundaries and time zone first so the lines are genuinely comparable. For divergence investigations, use Vortex Mind.

Known limitations / merchant FAQs

Q: How often does Orders / Day update? It refreshes on the standard data refresh and plots the trailing 30 days, so the most recent day fills in as orders land.

Q: Why does my Mercari dashboard show a different number? Mercari presents orders as a dated list, not a daily chart, so a hand count can differ at the day boundary or by time zone. This card applies one consistent day rule.

Q: Why does a day show zero orders? Days with no completed orders are plotted as zero rather than hidden, which keeps the weekly rhythm honest and makes quiet days visible.

Q: Can I customise the alert threshold? Yes, alert thresholds are configurable per profile in the Alert Rules tab. Adjust to match your business baseline rather than relying on the generic default.
