    Week 1; shared with Samuel Whitcombe, Head of Merchant Success

    B2B merchants say their sales teams struggle. How do their pipelines convert from lead to won deal, how long does it take, and what predicts winning or losing?

    Note to Daniel Kim — B2B pipeline health

    Daniel,

    Samuel and I need to give the B2B wholesale merchants (and our own leadership) a clear-eyed view of why their sales teams are struggling to close business. This feeds a joint recommendation Samuel and I are making next week on where to invest — better pipeline coaching/tooling for merchants vs. changes to how we structure stages, quotes and terms in the product. So I want the picture to be accurate more than exhaustive — pick your battles across the nights you have.

    Here's what I actually want to know, in plain terms:

    1. Where do deals die? Across the wholesale merchants, at what point in the journey from raw lead to signed deal do we lose the most opportunities? I want to know which stage is the graveyard, not just an overall conversion number.
    2. How long does it take to close, and is that getting better or worse? From a lead first showing up to a deal actually closing (won or lost), what's the typical cycle time, and has it been stretching out or shrinking over recent months?
    3. What separates a won deal from a lost one? Things like deal size, how many people/touches were involved before close, which rep or team owned it, or how old the opportunity got before it closed — anything that reliably shows up more on the winning side versus the losing side.
    4. Are some merchants or reps clearly struggling more than others? I'd like a sense of whether this is a widespread pattern across our B2B merchants or concentrated in a handful of accounts/teams, since that changes whether this is a product fix or a coaching fix.
    5. (If there's room) Does deal size or payment terms correlate with win rate or speed? Wholesalers care a lot about credit terms — I'm curious if longer terms or larger contract values are dragging out or killing deals.

    Priority order is 1, 2, 3 first — those directly shape the recommendation. 4 and 5 are valuable but can slip if you run out of slots this week.

    Keep each report to one clean question — I'd rather have four sharp answers than one crowded one. Flag anything that looks like a data quality issue rather than a real trend.

    Thanks — looking forward to the Friday memo.

    Patrick

    A note from the Head of Merchant Success, Samuel Whitcombe

    Subject: A few questions from the Merchant Success side

    Hi Daniel,

    Good to see this getting attention this week. A few things I'd love your analysis to help answer, from the merchant-health angle:

    1. For our B2B wholesaler merchants specifically, are deals actually stalling at a particular stage, or is it more that fewer leads come in to begin with? I want to know where the real friction sits before our QBRs.
    2. Among the accounts that do close, is there anything about them (size, how engaged they were beforehand, how long the courtship took) that separates the wins from the losses? I'm trying to understand whether our biggest merchants' sales teams are losing winnable deals or just working less promising ones.
    3. Is there a relationship between how long a deal has been open and its odds of closing at all — i.e. do stale pipelines quietly become risk, or do they usually still land eventually?

    Happy to compare notes before you finalize anything for Patrick.

    Best, Samuel

  3. Daniel Kim plans the night

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

    Night 1: going straight at Patrick's top three priorities (graveyard stage, cycle-time trend, won-vs-lost drivers), which also cover most of Samuel's three questions (stage friction, what separates wins/losses, implicitly sets up stale-pipeline-risk follow-up for night 2). All three reports scope to B2B wholesale tenants via an industry-text heuristic (industrial supplies / office equipment / wholesale) since there's no explicit 'B2B wholesaler' flag on tenants — I've asked the report to surface the merchant list so I can sanity-check the filter caught the right handful of tenants before going further. Kept each report to one grain: (tenant x stage) for the funnel, (month) for cycle time, and (won/lost) for the comparison, per the one-question-one-report rule. Held back Samuel's 'stale pipeline = risk' question and Patrick's #4 (merchant/rep dispersion) and #5 (terms/size correlation) for later nights once I see where the real friction shows up — no point spending slots on dispersion or terms analysis if the stage report shows everyone dying at the same place for the same reason.

    “Submitted. Summary of what the query does: - Scope: tenants whose industry matches industrial/office equipment/wholesale (ILIKE), per the brief. - Grain: one row per (merchant, pipeline stage), ordered by merchant name then stage order. - Measures: open count (is_closed=false), closed-won count, closed-lost count (both keyed to stage_id as the final stage), average opportunity amount and its currency code, plus the stage's default win probability and order — all as requested, with no time window and no FX conversion. - Used a LEFT JOIN from stages to the opportunity aggregates so stages with zero opportunities still appear (with zeros), which supports the "graveyard stage" and "zero opportunities" checks the analyst wants. Flagged in the submit note: average/currency are per (tenant, stage) without conversion — safe under the stated assumption that a tenant's opportunities are single-currency, but I couldn't verify that from a dry run since it reads no data. I also asked the analyst to check for any wholesale tenant returning zero stages/opportunities, since dry runs can't surface that either.”

    • The request, as Grace received it
      Report request from Daniel Kim (analyst for the Head of B2B Commerce):
      
      Title: B2B Wholesale Pipeline: Opportunities by Merchant and Stage
      Question: Across our B2B wholesale merchants, at which pipeline stage do the most opportunities get stuck or lost — i.e. which stage is the graveyard?
      Grain: one row per wholesale merchant (tenant) and pipeline stage
      Columns:
      - merchant (tenants.name)
      - pipeline name
      - stage name
      - stage order (sort_position)
      - default win probability (win_probability)
      - opportunities currently open at this stage (is_closed = false)
      - opportunities closed won with this as final stage_id
      - opportunities closed lost with this as final stage_id
      - average opportunity amount at this stage (in the opportunity's own currency)
      - currency_code
      Details: Scope to B2B wholesale merchants only: tenants where industry ILIKE '%industrial%' OR industry ILIKE '%office equipment%' OR industry ILIKE '%wholesal%' (per the company briefing's 'industrial supplies, office equipment' wholesalers). Use opportunities joined to opportunity_stages (stage_id) and pipelines, and tenants for the merchant name. For each (tenant, stage) pair count: opportunities where is_closed = false (currently sitting there), opportunities where is_closed = true and is_won = true and stage_id = this stage, and opportunities where is_closed = true and is_won = false (lost) and stage_id = this stage. Include avg(amount) per currency_code — do not convert currencies here since the grain is per-tenant so no cross-currency summing occurs. This is an all-time snapshot (all opportunities ever created through 2025-12-31), not time-windowed. Order by merchant name, then stage order (sort_position) ascending. Flag in the report notes if any wholesale tenant has zero opportunities or zero stages, since that would indicate the industry filter missed a merchant or the merchant doesn't use the CRM module.

    • GraceSubmitted. Summary of what the query does: - **Scope**: tenants whose `industry` matches industrial/office equipment/wholesale (ILIKE), per the brief. - **Grain**: one row per (merchant, pipeline stage), ordered by merchant name then stage order. - **Measures**: open count (`is_closed=false`), closed-won count, closed-lost count (both keyed to `stage_id` as the final stage), average opportunity amount and its currency code, plus the stage's default win probability and order — all as requested, with no time window and no FX conversion. - Used a `LEFT JOIN` from stages to the opportunity aggregates so stages with zero opportunities still appear (with zeros), which supports the "graveyard stage" and "zero opportunities" checks the analyst wants. Flagged in the submit note: average/currency are per (tenant, stage) without conversion — safe under the stated assumption that a tenant's opportunities are single-currency, but I couldn't verify that from a dry run since it reads no data. I also asked the analyst to check for any wholesale tenant returning zero stages/opportunities, since dry runs can't surface that either.
