  1. A business event lands on the Chief Executive Officer's desk

    Week 2; shared with Tobias Lindqvist, Chief Financial Officer

    The board meets at the end of January and wants a clear view of unit economics: per merchant, vertical and country, what Tidewick earns and what it costs us to serve them. Which merchants are worth growing, and which cost more than they bring?

    The manager, at the start of week 2

    Subject: Great first week — here's where I want to go next

    Hannah,

    This was exactly the kind of grounding I needed — thank you. A few things surprised me and one big new ask from the board that I need us to lead together with Tobias.

    What surprised me / needs explaining:

    • Your fee-revenue figure (€53k trailing twelve months) and Tobias's (€93.6k for calendar 2025) don't match, and neither does your "72% from top 5, stable" concentration story line up cleanly with his "65% from top 10, declining as we add merchants." Before this goes near the board I need these reconciled into one number and one trend — I don't want finance and analytics telling different stories about the same business.
    • The refund story looks more nuanced than "refunds are creeping up broadly." Tobias's team says apparel's ~20% refund rate is just normal for the category, and the real spike this quarter came from a few smaller non-apparel merchants. I'd like your root-cause work to confirm or correct that before we flag it as a trend versus a one-off.
    • Operations found that delivery performance is almost entirely a carrier issue, not a merchant or warehouse issue — the same merchant looks great on one carrier and bad on another, and one carrier partner has clearly been underperforming since November. That changes how I think about "merchant health" — some of what looks like a merchant problem may really be a carrier problem.

    The new board ask — unit economics by merchant, vertical and country:

    The board wants to know, plainly, what we earn from serving each merchant/vertical/country and what it costs us — so we can say which parts of the business are worth leaning into and which are quietly expensive. This is bigger than one report, so here's what I think it needs, and I want you and Tobias to scope it jointly this week rather than me prescribing the method:

    • On the earnings side, we seem to have good data (processing fees, volume). Platform-plan fees are apparently missing from the warehouse — Tobias, can your team supply that separately so we're not missing a real revenue line?
    • On the cost side, I don't think we've ever assembled this: fulfillment/carrier cost, refund and return handling, support load, and the engineering reliability issues (webhook failures, the cart-reminder bug) that generate extra support tickets. Some of this may not be cleanly attributable per merchant in the data — I want an honest read on what's knowable now versus what needs to be modeled or estimated.
    • The deliverable I need by month-end: a short ranked view of which merchants/verticals/countries are clearly profitable to grow, which are marginal, and which likely cost more to serve than they return — even if the first pass is directional rather than precise.

    My questions for this week:

    1. Can you and Tobias reconcile the revenue and concentration numbers into a single, agreed figure and trend I can quote to the board without contradiction?
    2. What would it take to build even a rough cost-to-serve picture per merchant/vertical/country — and what's your honest confidence in it, given the data gaps you've already flagged (platform fees, refund-to-payout matching, carrier cost attribution)?
    3. On refunds — is the increase really concentrated in a few merchants/verticals as Tobias's team suggests, or is it broader? I want to know whether this is a few accounts to manage or a trend to worry about.
    4. Separately, flag for me which of our top accounts (like Castell Fasteners, with its traffic drop and unpaid invoices) look at risk — I want a short "accounts to watch" list alongside the unit economics work, not buried inside it.

    Let's talk briefly before you lock in this week's requests so we spend the slots on the unit economics scoping rather than re-running what we already mostly know.

    Thanks, Maren

    A note from the Chief Financial Officer, Tobias Lindqvist

    Note to Hannah Brooks

    Hannah — a few things from the finance side as you scope the board unit-economics piece:

    1. What does each merchant actually net us, after processing costs? We only see the economics clearly once payouts are broken into gross, fee, and net — a merchant with huge volume but thin margin on our fee side could look better on revenue than it really is on contribution.
    2. How exposed are we on currency? We earn and hold balances in many merchant currencies against a EUR view for the board — I want to know where FX swings could meaningfully move the 2025 numbers or the 2026 budget.
    3. Who's slow to pay us, and where? For the B2B wholesalers especially, I'd like a sense of outstanding receivables and how long they're taking to settle — that's a cost of serving them that doesn't show up in the headline revenue.

    If there's room, a rough read on how refund patterns differ by vertical or country would help round out the "which merchants are worth growing" question.

    Happy to talk through before Friday's memo.

    — Tobias

  3. Hannah Brooks plans the night

    The analyst · week 2, night 3, request 1 of 3

    Big win on refunds: Q3 data confirms Kofi's example precisely — OfficeHub Nordic's refund rate jumped from a 2.99% baseline to 20.98% in Q3 (€23,268 refunded on just 45 orders), and it's already back to 0% by Q4, so it reads as a resolved one-off incident, not a trend. Combined with Q4's pattern (big Apparel merchants Cragsley/Marrowby actually improved), I'm confident the refund story is "a few concentrated incidents in small/mid merchants," not a broad trend — ready to write this up. On receivables, the aging report confirms ~€196.9k total outstanding, concentrated almost entirely in 7 B2B wholesalers, with Kontor24 Bürobedarf alone at €116.7k (59% of it, half of that in one single €49.4k invoice) — a much bigger story than Castell Fasteners alone. I also noticed something important for the "at risk" question: tenants.status itself (past_due/suspended/churned) looks like it reflects whether a merchant is behind on paying us (platform billing), distinct from the receivables report (which is their own customers owing them) — worth pulling directly as the cleanest churn signal. Separately, the cost-driver inventory showed Deskline Supplies at ~€1,038/shipment vs. Cragsley at ~€4/shipment — a 237x gap within similar/different verticals that's too extreme to use in a cost model without checking whether it's a real freight-cost pattern or a data outlier. Tonight: (1) the platform-billing-risk list, (2) a sanity check on the Deskline shipping-cost outlier, (3) a first directional vertical-level unit-economics rollup using only the inputs I already trust (fee revenue, shipping cost, refunds, tickets), explicitly caveated as a first pass.

    “Submitted. Summary of what the report does: - Grain: one row per merchant (tenant) currently in past_due, suspended, or churned status (excluding soft-deleted tenants). - Columns: merchant name, vertical, tenant status, tenure in days, days since last order placed, days since last settled (paid) payout, and trailing-12-month fee revenue in EUR. - Logic: last order and last paid payout are pulled via per-tenant MAX() CTEs; fee revenue sums payouts.fee_amount for status='paid' within 2025-01-01–2025-12-31, converting non-EUR currencies using the EUR→currency rate on the payout's paid_at date. - Ordering: churned → suspended → past_due, then by fee revenue descending, with merchant name as a final deterministic tie-break. I noted in the submission that the EUR conversion assumes exchange_rates gives an EUR→currency rate (dividing to get EUR), treats EUR payouts as already-EUR, and that recency columns are null for merchants with no qualifying orders/payouts.”

      Title: Platform billing risk: merchants past_due, suspended or churned
      Question: Which merchants are currently behind on paying us or already cut off, and how big/active are they — our clearest churn-risk signal?
      Grain: one row per merchant (tenant), filtered to status in ('past_due','suspended','churned')

      Details: Source: tenants filtered to status in ('past_due','suspended','churned') and deleted_at is null, left joined to orders (max placed_at per tenant_id, any status) and payouts (max paid_at per tenant_id where status='paid') for recency, and to payouts again for fee revenue (status='paid', paid_at in [2025-01-01,2026-01-01), converted to EUR via exchange_rates as_of paid_at date, matching the validated methodology). This is meant to be read as the platform-billing-health complement to last night's customer-receivables report (that one was about merchants' own customers owing them money; this one is about whether the merchant itself is behind with Tidewick). Order by tenant status (churned first, then suspended, then past_due), tie-break by fee revenue descending. Note total row count.

      Submitted to tonight's batch. Your work on this request is done.
    • GraceSubmitted. Summary of what the report does: - **Grain:** one row per merchant (tenant) currently in `past_due`, `suspended`, or `churned` status (excluding soft-deleted tenants). - **Columns:** merchant name, vertical, tenant status, tenure in days, days since last order placed, days since last settled (`paid`) payout, and trailing-12-month fee revenue in EUR. - **Logic:** last order and last paid payout are pulled via per-tenant `MAX()` CTEs; fee revenue sums `payouts.fee_amount` for `status='paid'` within 2025-01-01–2025-12-31, converting non-EUR currencies using the EUR→currency rate on the payout's `paid_at` date. - **Ordering:** churned → suspended → past_due, then by fee revenue descending, with merchant name as a final deterministic tie-break. I noted in the submission that the EUR conversion assumes `exchange_rates` gives an EUR→currency rate (dividing to get EUR), treats EUR payouts as already-EUR, and that recency columns are null for merchants with no qualifying orders/payouts.
