The main missing evidence is transactional: invoices, equivalent-scope quotes and entitlement schedules. More supplier announcements alone will not resolve it.
| Missing measurement | Next evidence collection | Publication rule |
|---|---|---|
| Actual annual club expenditure | Consented, redacted invoices and order forms, split by recurring and one-off cost | Report the sample size and perimeter; do not imply a league census |
| Comparable professional-package pricing | Matched quote requests for MLS, NWSL and group-use scenarios | Publish ranges only where scope is genuinely comparable |
| Independent purchasing-account count | Contracting entities, shared procurement and league-funded access | Separate clubs, accounts and participating users |
| Supplier contract volumes and renewal activity | Dated buyer-confirmed register | Deduplicate announcements and renewals; distinguish paid contracts from other partnerships |
| NWSL coverage completeness | Authorised competition-season inventories and samples | Publish percentages only against an explicit expected-match denominator |
| Market growth | Repeated measurement of the same purchasing cohort | Separate new clubs, price changes, wider scope and one-off projects |
How was evidence handled?
This review searched supplier documentation and announcements, league and FIFA publications, industry reporting, practitioner surveys, job boards, video-related material and podcasts. Recent evidence was prioritised, with older acquisitions and renewals retained where they explain current procurement choices.
Evidence labels: official disclosures establish what was announced; supplier claims establish advertised capability; calculated figures show their formula; scenarios expose their assumptions. No supplier sample, club contract or invoice was independently audited for this report.
Bottom line: the corrected customer population and recent integration activity are actionable. The expenditure scenario is useful for planning only. A market-wide revenue estimate, professional-stack price distribution and observed supplier-contract volume remain unsupported by the public evidence located.
