"Extra cash needed" = funding required so the bank account never goes below zero (raise, credit line, or slow the ramp). Assumes CAC flat at £43.38 (Menard/Rise evidence: CAC drifts only ~£10 from £10k→£150k/day at natural CAC), fixed costs £5,000/mo, VAT netted per order.
Cash position by month (net-60 terms)
The MER lag (scenario C) — why it feels worse while you scale
MER dips during every ramp leg because rebills lag spend by 3+ months, then recovers as cohorts mature. Judge scaling months on cohort paybacks, not blended MER.
