WMATA Missed Its 30-Day Payment Deadline on 42% of Invoices
Summary
WMATA's own Inspector General reviewed 44,641 payments to outside-party and miscellaneous vendors between January 2023 and February 2024 -- nearly $3 billion -- and found 18,792 of them, 42.1%, missed the transit agency's own 30-day Prompt Payment Policy. In a separate sample of the 26 highest-dollar payments in that population, worth $174.4 million combined, 21 (81%) were late, one by 1,967 days -- over five years -- and WMATA's own weekly monitoring report caught only two of those 21 late payments. The same audit found a sole-source contract that grew from $1,115,125 to $24,413,893 with no price estimate, contract award, or markup justification on file, and $61.4 million in sampled payments where offices bundled multiple purchase orders together in ways that blocked the standard three-way payment check.
A $3 billion population, and how much of it ran late
WMATA's Accounting Manual gives Program Offices 30 calendar days to pay a vendor invoice once goods or services are confirmed received. Of the 18,792 payments that missed that window⧉, 9,508 (21.3%) ran 31 to 60 days late, 3,700 (8.3%) ran 61 to 90 days, 1,876 (4.2%) ran 91 to 120 days, and 3,708 (8.3%) took more than 120 days to pay⧉ -- a fifth of the entire population still unpaid two months after the deadline, and roughly one payment in twelve still open past four months.

OIG's own sample did worse than the average
For a closer look, judgmentally selected the 26 highest-dollar Operating and Capital payments⧉ in the same two vendor categories -- $174,359,917.61 combined -- choosing them for size, timeliness, and whether they were international transactions. Only five of the 26 (19%) met the 30-day requirement⧉; the other 21 (81%), worth $95,464,892.30, were delayed, one by as much as 1,967 days -- more than five years⧉ past the due date.

| Paid within 30 days (5 payments) | 78,895,025.3 | This outlet's arithmetic: the sample's $174,359,917.61 total minus the audit's own $95,464,892.30 delayed total. The audit states the sample size (26) and the delayed count/total directly; it does not itself state the on-time dollar figure. |
|---|---|---|
| Delayed beyond 30 days (21 payments) | 95,464,892.3 | 81% of the sample by count; one payment was delayed 1,967 days, over five years. |
The monitoring report meant to catch this caught almost none of it
WMATA's own procedures require the A/P branch to produce weekly Aged Exception Reports flagging every outstanding invoice and escalating any that stay unresolved. reviewed 13 of those reports -- which should have captured all 26 sampled payments -- and found only two of the 26 delayed payments actually listed⧉. Digging further into those same 13 reports, separately identified three more vendors with the longest outstanding balances, $684,080.84 combined⧉, sitting outside the original sample. The A/P branch could not show it had ever followed up on them, and one vendor's invoices went unpaid for almost three years -- until OIG asked the Program Office directly, and WMATA processed the payment within days⧉.
Bundled orders and a contract that grew 22-fold with no paper trail
Nine of the 26 sampled payments -- 35% of the sample -- totaled $61,405,450.09 in bundled purchase orders⧉: Program Offices combining multiple POs into a single payment, which the audit found makes it harder for A/P to run the required three-way match between order, invoice, and receipt. Three more payments, $18,294,654.48 combined, lacked contract or payment-validation documentation⧉, all tied to the same Program Office.
One of those three, a sole-source Digital Advertising Displays contract, grew from $1,115,125 to $24,413,893 -- with no price estimate, no evidence of an actual contract award, and no justification for the 20% markup on the invoice⧉. Two more payments, $20,579.99 combined, were miscellaneous IT purchases processed with no evidence WMATA's Digital Modernization department ever vetted them for cybersecurity risk⧉ before payment, a review the agency's own policy requires. WMATA management concurred, in its own words, with nine of 's ten recommendations; on the tenth, it committed to a corrective action plan without using that word, and 's own comment deemed the response responsive all the same.

- 42.1% of WMATA's $3 billion in Outside Party and Miscellaneous vendor payments missed the transit agency's own 30-day deadline over 14 months. Nearly a fifth of the full population -- 9,508 payments -- was still unpaid 31 to 60 days after the due date; 3,708 payments ran more than 120 days late.
- 's own sample of the 26 highest-dollar payments did worse than the population average, and WMATA's monitoring tool missed almost all of it. 81% of the sample was delayed, one payment by 1,967 days, and the weekly Aged Exception Report designed to flag exactly this problem caught only 2 of the 21 late payments -- with three more high-balance vendors surfacing only when went looking on its own.
- More than a third of the sample's dollars moved through bundled purchase orders, and a sole-source contract grew roughly 22-fold with no price justification on file. $61.4 million in sampled payments had multiple POs combined in ways that blocked the standard three-way payment check, and a Digital Advertising Displays contract rose from $1,115,125 to $24,413,893 with no contract award or markup justification in the file.

The on-time counts, on-time dollar totals, monitoring-capture rate, and sole-source growth multiple are this outlet's own arithmetic on the audit's own itemized figures (methods and caveats in analysis.json); the audit itself states the underlying counts and dollar totals but not these derived shares.

WMATA's Office of Inspector General⧉ reviewed every payment the transit agency made to its Outside Party and Miscellaneous vendors between January 2023 and February 2024 -- 44,641 payments, nearly $3 billion⧉ -- and found that 18,792 of them, 42.1%, exceeded WMATA's own 30-day Prompt Payment Policy⧉. When then pulled the 26 highest-dollar payments in that population for closer review, the picture got worse, not better.
