On July 2，资环链金’s “five flows in one” reverse invoicing product system was officially connected to Industrial and Commercial Bank of China’s “three flows in one” reverse invoicing service，successfully issuing the first Leqi Platform reverse invoice after the cooperation between the two parties，realizing two-way empowerment between the industrial side and the financial side——the real transaction scenarios and business data on the industrial side，combined with the payment settlement and direct tax connection capabilities on the financial side，provided a replicable 链金 model for the industry to move from “extensive operation” toward “standardized development”。

The renewable resource recycling industry has long faced the structural challenge of “lack of source invoices”。When recycling enterprises purchase scrap products from upstream natural persons，natural persons generally do not meet the conditions for issuing invoices，leaving enterprises unable to obtain VAT input deduction vouchers and also lacking a basis for pre-tax deduction of corporate income tax。Since the State Taxation Administration issued relevant policies on “reverse invoicing” in April 2024，although the policy channel has been opened，in actual operations，recycling enterprises still commonly face practical challenges such as difficulty in verifying business authenticity，long transaction chains，and high tax compliance costs。

As the “fundamental base” of China’s resources and environment sector and a key central state-owned enterprise force in the recycled steel field，资环链金，relying on a national and functional recycled steel resource recycling and reuse platform，has continued to deepen its efforts in the research and development of reverse invoicing products。Its “five flows in one” reverse invoicing product，based on the platform’s integrated “transaction，service，and supervision” architecture，integrates three major capabilities：a transaction platform，a SaaS system，and a blockchain evidence storage platform，covering the complete business process from transaction matching，electronic contract signing，quality inspection and goods receipt，settlement and reconciliation，and direct invoicing to online payment，building a full-chain trusted evidence storage system for “business flow，logistics flow，invoice flow，capital flow，and information flow”。

Industrial and Commercial Bank of China has fully integrated enterprise-level payment settlement capabilities and Leqi direct-connect invoicing service capabilities into 资环链金’s product system，implementing a full-process automated closed loop of “payment means invoicing，invoicing means tax payment，and tax payment means treasury deposit”，realizing core functions such as compliant traceable records throughout the entire transaction fund process，automatic invoice-tax calculation and real-time withholding and treasury deposit of tax payments，and financial-grade real-name verification of transaction entities。Starting from July 1，2026，for natural-person sellers of scrap products with annual sales not exceeding 600,000 yuan，a portion of personal income tax will be prepaid at a reduced rate of 0.25%，and this cooperation enables this preferential policy to accurately reach every natural-person seller。

As of now，资环链金’s “five flows in one” reverse invoicing product has served 48 recycling enterprises and 23,000 natural-person sellers，issued a cumulative total of more than 160,000 invoices，and exceeded 24.2 billion yuan in invoiced amount。

It is understood that Industrial and Commercial Bank of China，as one of the first commercial banks to obtain the State Taxation Administration’s “Leqi Joint Use” reverse invoicing qualification，is one of the five approved Leqi Joint Use platforms。The successful issuance of this reverse invoice marks a key breakthrough in the digital reverse invoicing solution for the renewable resource industry，providing a practical and implementable path for tax compliance and policy implementation in the industry。（Source：资环链金）
