Service providers for Mexico's Pemex are unable to submit new invoices for services performed nearly a year ago even as the state-owned company also struggles to pay down past bills, sources say.
These unsubmitted invoices do not appear in Pemex's financial records or in its monthly supplier debt reports, three Pemex suppliers who work mostly in the northern region of the Gulf of Mexico told Argus.
Pemex provides vendors a system to submit bills for review and processing, leading to an invoice codifying payments and discounts (Copades). At this stage, Pemex certifies the pending invoice, making it part of the company's monthly supplier report —a transparency measure implemented in 2021.
Pemex reduced its overdue debts to service providers by 6pc from May-July, with Ps126.4bn ($6.78bn) in unpaid invoices as of 31 July, down from Ps133.9bn in May.
But a significant amount of unbilled work remains because Pemex has not issued the necessary Copades for vendors to begin the payment process, and some of the bills date back to work performed in September, according to two of the vendors.
Without the Copades, companies must classify these debts as uncollectible, one vendor said.
The issue is concentrated in Mexico's northeast maritime region, where Pemex produces about half of its crude and gas output, according to the vendors. This region includes the Cantarell and Ku-Maloob-Zap fields.
Pemex has requested vendors to perform tasks in the area, but the company then claims there is no budget allocated for those bills, the vendors said. This unbilled work adds to Pemex's recognized debt to suppliers, but the size of this unrecognized debt is impossible to estimate, the vendors added.
Pemex's unpaid invoices and short-term vendor debts stand at record-high levels, despite receiving over $70bn in government support since 2019.
