Large transaction volume at renewable resource recycling bases but invoices cannot keep up? Kailing Technology's reverse invoicing solution gives every purchase a complete evidence chain

I. Transactions are running, invoices are being chased, and they can never be caught up with

A medium-sized renewable resource recycling base easily handles over a hundred purchases per day. Waste paper, scrap steel, waste plastics, waste glass... Scattered households ride tricycles in, weigh, inspect goods, receive cash, and leave. The whole process ends in ten minutes, but the mess left for finance may take ten days to handle.

Individual suppliers have neither the ability nor the willingness to issue invoices. What they care about is "what is the scrap iron price today" and "when will the money arrive"—as for invoices, that is the enterprise's business.

As a result, the finance team falls into an absurd daily routine: the business side operates at high speed every day, with transaction flows rushing along, but the invoice side is always lagging. At month-end reconciliation, a large amount of acquisition expenditure is recorded under "provisional estimate," and the input VAT invoice gap is shocking.

This is not a management problem, but a structural contradiction—the transaction counterparties determine that the traditional invoicing model simply cannot work in this industry.

II. Without invoices, the consequences are more serious than imagined

Many owners of recycling bases think, "Everyone in the industry is like this, and the tax bureau understands." This wishful thinking no longer holds in the face of China Golden Tax Phase IV.

At the tax burden level: No input VAT invoice means VAT cannot be deducted, and corporate income tax cannot be deducted before tax. For a base with annual procurement of 100 million, the comprehensive tax burden may increase by 8 million to 12 million as a result.

At the audit level: China Golden Tax Phase IV's data comparison capability far exceeds the past. Bank statements show you making large daily expenditures, but corresponding input VAT invoices are very few—this characteristic of "severe mismatch between capital flow and invoice flow" is exactly the signal that tax early warning models focus on capturing.

Business level: More and more downstream customers (especially large paper mills, steel mills, and recycled plastics processing enterprises) require suppliers to provide a complete compliant invoice chain. Without invoices, not only is one's own tax burden high, but even customers may be lost.

III. Reverse invoicing: the institutional gateway has opened

In 2024, the State Taxation Administration clarified: eligible resource recycling enterprises may issue purchase invoices under reverse invoicing to individuals selling scrap products.

This means companies no longer need to wait for individual sellers to go to the tax bureau for invoice issuance; instead, when the acquisition occurs, the company proactively issues an invoice. The invoice issued carries the "scrap product acquisition" label and can serve as a compliant input VAT deduction voucher.

The policy has provided the path, but how to walk it is another matter.

Reverse invoicing is not "invoice whenever you want." The tax bureau requires enterprises to prove the authenticity of every transaction—who sold it, what was sold, how much, at what price, how it was transported, and where the money was paid. If an invoice is issued but complete business evidence cannot be provided, there is still a risk of being deemed false invoicing.

For recycling bases with hundreds of transactions per day, organizing these evidence chains manually is almost an impossible task.

IV. Kailing Technology's approach: let the evidence chain be automatically generated during the transaction process

The design logic of the Kailing Technology Reverse Invoicing solution is not "supplementing invoices afterward," but "archiving at transaction"—from the moment each purchase occurs, all key information automatically flows, associates, and is stored as evidence in the system.

Individual supplier entry: digital file creation

When individual suppliers deliver to the site for the first time, they complete real-name authentication via facial scan on their mobile phone. The system automatically collects ID card information, binds a bank card, and signs the electronic "Reverse Invoicing Consent Form." The whole process takes 3 minutes, completed once, and reused directly for subsequent transactions.

The system simultaneously performs identity verification: confirming that the natural person is not the legal representative, supervisor, senior manager, or sole proprietor of any enterprise, and confirming that their cumulative annual invoicing amount has not exceeded 5 million yuan. Those who do not meet the conditions are blocked at the filing stage.

Weighing and inspection: business data enters the chain in real time

After individual suppliers deliver on site, a delivery order is created based on the electronic contract. Weighbridge data can be entered manually or automatically captured via direct connection to the electronic weighbridge system. Photos of the front and rear of the vehicle, actual goods photos, and quality inspection results—all on-site information is uploaded instantly via mobile and automatically bound to this transaction.

For trucks of 12 tons or more, the system supports direct connection to BeiDou positioning to obtain logistics trajectories, further strengthening evidence for the transportation segment.

Settlement invoicing: one-click completion, no need to log in to the tax bureau

After quality inspection passes and settlement approval is completed, the system automatically executes:

Verify the retail investor's annual limit of 5 million (blocked if exceeded)

Call the electronic tax bureau interface to issue fully digitalized e-invoices tagged "scrap product purchase" via reverse invoicing

Positive invoices or negative red-letter reversals can both be operated with one click in the system

Finance staff do not need to log into the electronic tax bureau throughout the entire process, nor manually fill in invoicing information. The system uses a login-free mode to directly connect to tax bureau interfaces; a single invoice takes seconds from initiation to completion.

Payment archiving: five-flow closed loop

After invoice issuance is completed, the system triggers the payment process. It supports automatic payment via bank-enterprise direct connection (China Merchants Bank free API recommended), and also supports uploading receipts after offline payment.

Ultimately, each transaction forms a complete five-flow archive:

Contract flow: electronic procurement agreement + reverse invoicing consent form

Business flow: delivery note + weighbridge ticket + quality inspection certificate + vehicle photos + cargo photos

Logistics: Beidou trajectory or paper transportation documents

Tax flow: fully digitalized e-invoices (PDF/OFD/XML source files)

Fund flow: bank receipt

Five materials are automatically linked to the same transaction, supporting multi-dimensional retrieval by individual seller, time, amount, category, etc. During a tax audit, one-click access presents the complete evidence chain immediately.

V. Solving more than just the "invoicing" problem

Many recycling bases initially only wanted "to be able to issue invoices." But after actual go-live, they find that this system changes the management approach of the entire purchasing business:

Cash transactions become online payments. After individual suppliers bind bank cards, payment is directly deposited to the card. This eliminates the untraceability of cash transactions and reduces the safety risks of on-site management.

Individual supplier information from nothing to something. In the past, individual sellers came and went, and the base knew nothing about the upstream supply structure. Now every individual seller has a digital file, with transaction frequency, cumulative amount, and cargo categories clear at a glance, providing data support for procurement decisions.

Finance changes from "chasing invoices" to "managing data." The finance team no longer needs to centrally supplement invoices, reconcile accounts, and chase orders at month-end. Daily work becomes monitoring exceptions, analyzing costs, and optimizing tax structures on the system dashboard.

Downstream customer trust is enhanced. Suppliers able to provide a complete and compliant invoice chain are clearly more competitive in large-client bidding and long-term cooperation.

The renewable resource recycling industry is undergoing an irreversible compliance transformation. Things that could once be glossed over by relying on "industry practice" have nowhere to hide in the face of data-penetrating regulation. The sooner the evidence chain is made workable, the sooner risks are kept out. This is not a multiple-choice question; it is a question of time.
