|                               |                                                                                                                                                                                                                          |
| ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **What it counts**            | `DATE_HISTOGRAM(week, CARDINALITY(customer.id))` over the 90-day window. Each week shows the distinct customer count for that week. A customer who ordered in three different weeks contributes to three weekly buckets. |
| **API endpoint**              | `Admin GraphQL. Order.customer.id`, bucketed by `Order.createdAt` week.                                                                                                                                                  |
| **VAT / tax treatment**       | Not applicable (count metric).                                                                                                                                                                                           |
| **Shipping**                  | Not applicable.                                                                                                                                                                                                          |
| **Discounts**                 | Not applicable.                                                                                                                                                                                                          |
| **Refunds**                   | Refunded-order customers still count.                                                                                                                                                                                    |
| **Cancelled / voided orders** | Cancelled-order customers count if customer was attached.                                                                                                                                                                |
| **Currency**                  | Multi-currency safe.                                                                                                                                                                                                     |
| **Channels / sources**        | Online + POS-with-account + B2B contribute. POS-guest excluded.                                                                                                                                                          |
| **Aggregation note**          | Weekly customers sum to MORE than monthly customers (a customer who orders in 4 weeks counts 4 times in the weekly view but once in the monthly view). Use this card for shape, not summed totals.                       |
| **Time window**               | `90D` (typically weekly buckets)                                                                                                                                                                                         |
| **Alert trigger**             | None on this card directly; significant drops surface via the [Customer Count](/nerve-centre/kpi-cards/shopify/unique-customers) period comparison.                                                                      |
| **Roles**                     | owner, marketing                                                                                                                                                                                                         |

## Worked example

A UK DTC apparel brand on Shopify. Period: 12 Feb 26 to 12 May 26. Weekly distinct-customer counts:

| Week starting | Distinct customers | New customers (subset) | Returning (subset) | Notes                             |
| ------------- | ------------------ | ---------------------- | ------------------ | --------------------------------- |
| 12 Feb 26     | 478                | 281                    | 197                | Steady                            |
| 19 Feb 26     | 502                | 298                    | 204                |                                   |
| 26 Feb 26     | 511                | 305                    | 206                |                                   |
| 04 Mar 26     | 1,142              | 854                    | 288                | **Spring drop launch, paid push** |
| 11 Mar 26     | 928                | 619                    | 309                | Lift continues                    |
| 18 Mar 26     | 612                | 312                    | 300                | Tapering                          |
| 25 Mar 26     | 521                | 214                    | 307                | Returning steady, new normalising |
| 01 Apr 26     | 488                | 198                    | 290                |                                   |
| 08 Apr 26     | 461                | 187                    | 274                |                                   |
| 15 Apr 26     | 471                | 191                    | 280                | Easter push                       |
| 22 Apr 26     | 502                | 211                    | 291                |                                   |
| 29 Apr 26     | 488                | 188                    | 300                |                                   |
| 06 May 26     | 491                | 189                    | 302                |                                   |

Five things to notice:

1. **The 04 Mar spike is the spring drop wave.** Distinct weekly customers more than doubled, driven by ad-spend lift. The wave decayed across 3 weeks (1,142 → 928 → 612), a typical drop-launch shape. Returning-customer count remained elevated for longer than new-customer count (304 vs 854 → 191), evidence the returning cohort responded later to the email campaign than new acquisition responded to ads.
2. **The acquisition wave didn't lift the returning baseline.** Pre-drop returning was 197 to 206 / week; post-drop 274 to 302 / week. That is a 35% lift in returning customers maintained for 8 weeks. Some of those new acquisitions converted into early-repeat buyers; the rest of the lift is the existing base coming back for the new collection. Pair with [New Customers](/nerve-centre/kpi-cards/shopify/new-customers) to confirm the cohort split.
3. **Returning-customer steadiness is the retention health signal.** A flat 290 to 305 returning customers / week post-spike means the retention engine is steady. A step-down to 200 returning would be a churn alarm even with new-customer surge masking the headline.
4. **Easter (15 Apr) shows a small bump.** Acquisition campaigns produce visible week-level signatures here; you can audit campaign effectiveness against this card directly. A campaign that produces no visible lift in the weekly distinct count almost certainly did not work.
5. **POS-guest checkout invisible.** The brand's pop-up retail event on 21 Mar at a London market generated 80+ in-person sales but most without email capture; weekly distinct-customer count does not reflect them. POS-guest is a known gap for omnichannel brands.

## Sibling cards merchants should reference together

Customer trend is the timeseries view of [Customer Count](/nerve-centre/kpi-cards/shopify/unique-customers). Pair with these for context:

| Card                                                                                       | Why pair it with Customer Trend | What the combination tells you                                                                                  |
| ------------------------------------------------------------------------------------------ | ------------------------------- | --------------------------------------------------------------------------------------------------------------- |
| [Customer Count](/nerve-centre/kpi-cards/shopify/unique-customers)                         | The 30D summary view.           | Trend reveals the shape; count gives the headline.                                                              |
| [New Customers](/nerve-centre/kpi-cards/shopify/new-customers)                             | Acquisition subset over time.   | New-vs-returning split by week shows the engine driving the headline.                                           |
| [Repeat Rate](/nerve-centre/kpi-cards/shopify/repeat-customer-rate)                        | Retention proportion.           | A rising customer trend without rising repeat rate = pure acquisition; sustainable only with the funnel funded. |
| [Orders Over Time](/nerve-centre/kpi-cards/shopify/orders-over-time)                       | Order timeseries counterpart.   | Orders per customer per week = frequency.                                                                       |
| [Revenue Over Time](/nerve-centre/kpi-cards/shopify/revenue-over-time)                     | Revenue timeseries.             | Revenue ÷ customer trend = revenue per customer per week.                                                       |
| [Churn Risk](/nerve-centre/kpi-cards/shopify/customer-churn-risk)                          | Lapsed cohort.                  | A flat customer trend masking rising churn is a leaking-bucket alarm.                                           |
| [`google_ads.google_spend_over_time`](/nerve-centre/google_ads/google_spend_over_time)     | Acquisition channel input.      | Compare ad-spend timeseries to customer trend; the lag and lift reveal CAC efficiency.                          |
| [`google_analytics.ga_users_over_time`](/nerve-centre/google_analytics/ga_users_over_time) | Top-of-funnel counterpart.      | GA4 users vs Shopify customer trend = funnel conversion shape.                                                  |

## Reconciling against the vendor's own dashboard

**Where to look in Shopify Admin:**

[Analytics → Reports → "Customers over time"](https://admin.shopify.com/reports/customers_over_time) → set the date range to match this card and the resolution to weekly. Shopify's report should align week-to-week with this card.

Other Shopify Admin views:

* **Reports → First-time vs returning over time**: shows new vs returning segments of the same trend; companion view.
* **Reports → Sales by month**: revenue companion; pair to derive revenue-per-customer trend.
* **Apps like Polar Analytics, Triple Whale**: build richer customer-trend cohort views (acquisition cohorts, retention curves). Useful complements.

**Why our number may legitimately differ from Shopify Admin:**

| Reason               | Direction              | Why                                                                                                                                  |
| -------------------- | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| **Time zone**        | Boundary days          | Shopify uses store time zone; Vortex IQ uses store time zone for daily buckets but UTC for window edges.                             |
| **Bucket alignment** | Either                 | "Week" can start Mon (ISO) or Sun (US). Shopify defaults to Sun-start; Vortex IQ to Mon-start (configurable). Verify when comparing. |
| **Test orders**      | Ours slightly higher   | The card does not yet filter `Order.test = true`.                                                                                    |
| **Customer merging** | Transient              | Pre-merge data may show duplicates; reconciles after merging.                                                                        |
| **Channel filter**   | Either                 | Shopify can be filtered by sales channel; this card aggregates.                                                                      |
| **Sync lag**         | Ours lower for "today" | 5 to 15 minute lag. The latest week's bar will rise during the day.                                                                  |

**Cross-connector reconciliation:**

| Card                                                                                           | Expected relationship          | What causes legitimate divergence                                                   |
| ---------------------------------------------------------------------------------------------- | ------------------------------ | ----------------------------------------------------------------------------------- |
| [`google_analytics.ga_users_over_time`](/nerve-centre/google_analytics/ga_users_over_time)     | GA4 users >> Shopify customers | Conversion rate ties them.                                                          |
| [`klaviyo.klaviyo_subscribers_over_time`](/nerve-centre/klaviyo/klaviyo_subscribers_over_time) | Email signup vs purchase trend | Often diverge; email signups are top-of-funnel, customer trend is bottom-of-funnel. |

## Known limitations / merchant FAQs

**Why does the trend not sum to the 30D customer count?**
Because the same customer can order in multiple weeks. A customer who orders in 4 weeks counts 4 times in the weekly view but once in the 30D distinct view. Use this card for shape (week-over-week), not for summed totals.

**Why is the latest week's bar lower?**
Sync lag plus partial-week. The current week is in progress; bars are partial until end of week. Yesterday and earlier weeks are caught up.

**My weekly trend has a strong day-of-week pattern, why?**
Weekly bucketing usually smooths day-of-week effects, but if a brand's promotion calendar lands on specific days (e.g. always-Friday drops), week-on-week distinct customers will reflect campaign timing more than baseline behaviour.

**Multi-store, can I see the combined customer trend?**
No, each store is a separate integration. Multi-store rollups are on roadmap.

**Multi-currency, any impact?**
None on the count; weekly customer trend is currency-blind.

**Shopify Plus vs basic?**
No definitional difference. Plus stores typically have larger absolute numbers; the trend shape is qualitatively similar.

**Refresh cadence?**
Webhooks fire within seconds; index lag 5 to 15 minutes. Weekly buckets recompute on each ingest.

**B2B vs DTC, any difference?**
B2B customer counts are smaller and more event-driven; the trend can show large weekly swings tied to specific account activity. DTC trends are smoother. Mixed B2B + DTC stores benefit from filtering by tag (manual today; on roadmap).

**The trend dropped sharply last week, what should I do?**

1. Cross-reference [Orders Over Time](/nerve-centre/kpi-cards/shopify/orders-over-time). Did orders drop too? If yes, real volume issue; if no, customers might be ordering more per visit.
2. Cross-reference [Revenue Over Time](/nerve-centre/kpi-cards/shopify/revenue-over-time). A flat customer count + flat revenue suggests this is real, not artefact.
3. Check ad spend channels: a paused or under-performing ad campaign is the most common cause of a single-week customer drop.
4. Check site performance: a site outage or checkout error in the affected week often correlates.
5. Check email programme: a missed weekly campaign can show up as a returning-customer dip.
