Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Card class:** [Non-Hero](/nerve-centre/overview#card-classes-explained) • **Category:** [Marketplace](/nerve-centre/connectors#connectors-by-type) ## At a glance > **Revenue Over Time** plots your gross Mercari sales across the last 90 days as an area chart. It surfaces the trend, the seasonal swings, and the lift you get from re-listing or running a promotion. | | | | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **What it counts** | Gross sales revenue from completed Mercari orders, charted day by day across a rolling 90-day window. | | **Sample type** | Backend API data from Mercari, refreshed on the standard data refresh. | | **Why it matters** | A single live number hides direction. This chart shows whether you are growing, plateauing, or sliding, and lets you tie revenue moves to specific actions like a price drop or a re-list. | | **Reading the value** | Read the shape, not a single point. A rising slope is healthy; flat or falling stretches are cues to refresh listings or adjust pricing. | | **Currency** | currency | | **Time window** | `90D` | | **Alert trigger** | `-` | | **Sentiment key** | `mer_revenue_trend` | | **Roles** | owner, finance | ## Calculation Vortex IQ buckets the gross sale value of completed Mercari orders by day and renders the series as an area chart spanning the trailing 90 days. The figure is gross revenue before Mercari's selling and payment-processing fees, so it tracks top-line sales rather than net payout. Days with no sales appear as zero points, keeping the trend line continuous. ## Worked example *A representative reading of **Revenue Over Time** for a typical Mercari reseller.* A trading-card seller reviews the chart on 20 Jun 26 and sees revenue hovering around $40 a day through late May, then stepping up to roughly $90 a day after a 25 May 26 re-list that pushed dormant items back into the 7-day freshness boost. The chart makes the cause and effect obvious, so the seller schedules a recurring re-list cadence. Because this card has no alert trigger, it is a read-and-interpret tool rather than a watchdog. Pair it with total revenue for the headline figure and average order value to see whether growth comes from more orders or pricier ones. When the trend bends, Vortex Mind traces upstream causes such as a freshness-boost expiry or a fee change, and Ask Viq answers plain-English questions like "what drove the jump in my sales after 25 May?" ## Sibling cards merchants should reference together | Card | Why merchants reach for it | | ------------------------------------------------------------------------ | --------------------------------------------------------------------- | | [`mer_total_revenue`](/nerve-centre/kpi-cards/mercari/total-revenue) | Gives the single headline revenue figure behind the trend line. | | [`mer_aov`](/nerve-centre/kpi-cards/mercari/average-order-value) | Shows whether a rising trend comes from more orders or higher prices. | | [`mer_fee_total`](/nerve-centre/kpi-cards/mercari/marketplace-fees-paid) | Reveals how much of the gross trend Mercari takes in fees. | | [`mer_listings_active`](/nerve-centre/kpi-cards/mercari/active-listings) | Connects revenue swings to how many items were live to sell. | ## Reconciling against Mercari **Where to look in Mercari's own dashboard:** In the Mercari app, your sales history and completed-order list show each transaction with its sale price and date. Summing those sale prices over a date range should approximate the area under this chart for the same window, before any fee deductions. **Why the Vortex IQ value may legitimately differ:** | Reason | Direction | What to do | | --------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | ------------------------ | | **Period boundary.** The chart uses a rolling 90-day window, so the start date shifts daily and may not match a fixed calendar range you pick in Mercari. | Variable | Match the period range. | | **Time zone.** Orders near midnight can fall into a different day depending on the time zone used to bucket them. | Marginal | Confirm time zone match. | | **Filter scope.** This card charts gross sales before fees, so it will read higher than a net-payout view. | Variable | Match filter settings. | **Cross-connector reconciliation:** Compare the overall trend against your accounting or bank records to confirm the gross sales pattern. For divergence investigations, use Vortex Mind. ## Known limitations / merchant FAQs **Q: How often does Revenue Over Time update?** It refreshes on the standard Vortex IQ data refresh, with the most recent day filling in as new completed orders arrive. **Q: Why does my Mercari dashboard show a different number?** This chart plots gross sales before fees over a rolling 90-day window. If you total a fixed calendar range in Mercari, or read a net-of-fees figure, the comparison will diverge until you align the window and the fee treatment. **Q: Does the chart show net payout or gross sales?** It shows gross sales revenue before Mercari's selling and payment-processing fees. To see what actually reaches your balance, cross-reference the marketplace fees and net-revenue cards. **Q: Can I customise the alert threshold?** Yes, sensitivity thresholds are configurable per profile in the Sensitivity tab. Adjust to match your business baseline rather than relying on the generic default. *** ### Tracked live in Vortex IQ Nerve Centre *Revenue Over Time* is one of hundreds of KPI pulses Vortex IQ tracks across Mercari and 70+ other ecommerce connectors.
