“Does net equal gross minus fee cleanly for payouts in every currency, or do certain currencies show persistent drift in that basic arithmetic, separate from the refund timing issue already found?”
Fictional people at a fictional company, each played by a language-model agent. Who they are and what they are told
Week 1; shared with Tobias Lindqvist, Chief Financial Officer
Before the board pack goes out, Data must certify the key metrics. Do revenue, orders, customers, refunds and payouts agree wherever they are recorded, and where they do not, why not and by how much?
The manager, at the start of week 1
Subject: Certifying the key metrics before the board pack — what I need from you this week
Hi Yuki,
Tobias and I have to certify revenue, orders, customers, refunds and payouts before they go into the board pack. "Certify" means we're telling the board these numbers are reconcilable — so this week's job is to find out where the different places we record these figures agree, where they don't, and whether any gap is big enough to change the story we tell. If something doesn't reconcile, I need to know why and by how much, not just that it's "close enough." That feeds directly into the go/no-go Tobias and I give on the board pack, so please prioritize breadth across the five metrics over depth on any one of them — we can always dig deeper next week on whichever one looks shakiest.
You only have a handful of report slots a night, so here's what matters most to me, roughly in priority order:
Please flag anything you find inconsistent together with your best read of why, and roughly how big the discrepancy is in practice — that's what Tobias and I need to decide whether we can certify as-is, certify with a caveat, or need to hold a number back.
Thank you — I know this is a lot for one week. Let's talk before you spend your first slot tonight if you want to sanity-check the plan.

Subject: What I need for the revenue/payout certification
Hi Yuki,
A few things from my side as you scope this week's work:
If anything else jumps out while you're in there — especially around currency conversion timing or refund treatment — flag it even if it's outside these three.
Thanks, Tobias

Night 3 closed out two big open questions. The refund-inclusive order-status report shows the original 22% fulfilled gap was almost entirely a status-filter artifact: captured payments that later moved to refunded or partially_refunded status were invisible to a captured-only filter. Once included, the real residual gap is 0.9% for fulfilled orders and 5.3% for refunded orders, and the cancelled bucket is fully explained by orders cancelled before any charge plus clean full-refund treatment (net collected is exactly 0) for the ones that were charged. That is good news: orders trace cleanly to money collected once refund statuses are included. The refund-timing report found something genuinely structural: 85.5% of refund dollars are processed after the original payment's payout already settled, 20.9 days later on average, and payout_items has a one-row-per-payment constraint, so there is no clean slot in any payout to tie that later clawback back to the original sale. That explains the earlier volatility and is a real traceability gap to flag to Tobias rather than something I can fully resolve with one more query. The customer-headcount report shows a huge range from 11,258 total accounts down to 411 with an active subscription, with status equals active nearly meaningless as an activity signal since it covers 99.3% of all accounts. Tonight I am closing out the two asks not yet touched, Tobias's B2B receivables question and Rosa's currency and timestamp distortion question, plus one more targeted test of whether gross minus fee equals net holds consistently across currencies, tested in native currency to avoid any FX conversion noise contaminating that specific check.

“Query compiles with the expected columns. Submitting.”
“Submitted. The report groups payouts by native currency_code over 2023-01-01 to 2025-12-31 (scoped via created_at), with payout counts and native-currency totals for gross, fee, and net, plus the arithmetic drift (net - (gross - fee)) and that drift as a percent of gross — exactly as specified, with no FX conversion applied.”

Yuki Tanaka's memo to Rosa Van den Berg at the end of the week:
3. Refund timing, not a calculation error, breaks clean per-payout traceability. (Refund timing vs payout settlement; Payout net-formula drift by currency) 85.5% of refund euros are processed after the original payment's payout already settled (avg 20.9 days later), and payout_items allows only one row per payment ever — so a later clawback has no slot in the original payout. Checked in native currency (no FX noise) across all 6 currencies, net is consistently below gross-fee by -7.7% to -18.4%, in line with refund volumes — i.e., net ≈ gross − fee − refunds, just not within a single payout row. Confident no money is double-counted or hidden; open: we cannot currently point to which specific payout absorbed a given refund — that's a real reporting/traceability gap, not a loss.

Report request from Yuki Tanaka (analyst for the Head of Data): Title: Payout net-formula drift by currency Question: Does net equal gross minus fee cleanly for payouts in every currency, or do certain currencies show persistent drift in that basic arithmetic, separate from the refund timing issue already found? Grain: currency code, using the payout's native currency with no FX conversion applied Columns: - currency_code - payout_count - gross_native_total - fee_native_total - net_native_total - net_check_diff_native - net_check_diff_pct Details: Scope: all payouts across the full history from 2023-01-01 to 2025-12-31, grouped by payouts.currency_code, deliberately kept in native currency with no EUR conversion so this checks pure arithmetic consistency without introducing any FX rounding or rate matching as a confound. payout_count is the count of payouts in that currency. gross_native_total is the sum of payouts.gross_amount. fee_native_total is the sum of payouts.fee_amount. net_native_total is the sum of payouts.net_amount. net_check_diff_native is net_native_total minus the quantity gross_native_total minus fee_native_total, which should be close to 0 if net equals gross minus fee holds. net_check_diff_pct is net_check_diff_native divided by gross_native_total, times 100, rounded to 2 decimals. Table: payouts. Order by payout_count descending. Check your query with the warehouse's dry_run tool, then hand it in with submit.
