Scrap collection stations collecting copper, aluminum, and iron from individual sellers without invoices and with mismatched input items? Kailing Technology's reverse invoicing business five-flow integrated ledger management compliance closed loop
Scrap metal recycling cannot avoid a dead knot: copper, aluminum, and scrap steel mostly come from small sellers who roam the streets. These small sellers are neither enterprises nor able to issue VAT invoices. The scrap station receives cart after cart of goods, yet the books always lack an input invoice—input cannot be matched, accounts do not match reality, profits are eaten away by taxes out of thin air, and when an audit comes, it cannot be explained clearly. Kailing Technology's correct solution is to take two steps together: first use reverse invoicing, whereby the recycling enterprise compliantly issues VAT invoices to individual sellers, filling back the missing input invoices; then use integrated five-flows business ledger management to automatically aggregate the five lines of self-certification, contract, business, tax, and funds into one ledger, so that every input invoice corresponds to a real transaction, achieving accounts matching reality and a closed input loop.
▍Why is the copper, aluminum, and iron in individual sellers' hands always "input mismatched, books inconsistent with reality"
The daily routine of a scrap collection station is to use real money to collect copper, aluminum, and scrap steel from individual sellers one by one. Cash on delivery and goods on receipt looks satisfying, but once it hits the books, everything is awkward. The problems are concentrated in three aspects.
- Large input gap: What is collected is real goods and what is paid is real money, but individual sellers cannot issue VAT invoices, so this portion of cost cannot obtain input deductions. Output VAT is still paid, while input items remain empty. The larger the scale, the more profit is eroded.
- Accounts do not match reality: Without invoices linking everything together, how much goods the warehouse received, how much cost was recorded in the books, and how much was paid by the bank are three numbers each telling its own story. Without an evidence chain binding them together, the month-end reconciliation simply "doesn't match up."
- Cannot explain in an audit: When truly audited, who sold the goods, where the goods came from, and to whom the money was paid can only be pieced together from scattered receiving receipts and transfer screenshots; there is also no confidence about whether retail sellers can legally be sellers, and the risk of back taxes and fines always hangs overhead.
Ultimately, what scrap collection stations lack is not supply, but a mechanism that turns "real receipt of goods, real payment" into compliant input VAT vouchers that can withstand scrutiny at any time.
▍Reverse invoicing: compliantly "recover" input VAT invoices that individual sellers cannot issue
Reverse invoicing, in plain terms, means invoicing in the opposite direction—no longer waiting for individual sellers to issue invoices to the enterprise, but instead having qualified recycling enterprises issue VAT invoices in reverse to natural person sellers. The policy basis is State Taxation Administration Announcement No. 5 of 2024. Since April 29, 2024, resource recycling enterprises may issue reverse invoices to natural persons selling scrapped products, turning that long-dangling input segment into compliant, deductible, and traceable invoices.
It should be noted that reverse invoicing is not something "anyone can issue, to anyone." Legal representatives, directors and senior executives, and registered individual businesses cannot act as individual sellers. Issuing to the wrong party still requires back taxes and penalties. Therefore, "checking the entity before invoicing" is the first gate in this chain and must be blocked upfront in the system.

▍First identify the person: individual suppliers scan to create a file, with verification and interception before invoicing
The starting point of the Kailing Technology Reverse Invoicing Platform link is not invoicing, but "identifying the person." When an individual seller arrives at the store, they can scan a code to complete registration as an individual supplier, filling in name, ID number, mobile number, account bank, and bank card, and selecting the recycling type according to business scope—agricultural scrap steel, manufacturing scrap steel, other scrap steel (including stainless steel), etc., are clearly listed. After submission, it enters pending review, and only after enterprise approval can the person trade as a formal seller.
The file creation step also carries risk control: here the system connects to subject qualification verification, and legal representatives, directors and senior managers, and registered individual businesses are identified and blocked, plugging the hidden risk of "invoicing the wrong target" at the source, so every subsequent reverse invoice can be issued with confidence.

▍One record per truckload: goods order management makes the "business flow" real
Once the person is verified, the next step is to accurately record the goods. Each time a truckload of scrap metal is received, a goods ticket is generated in goods ticket management, with the goods ticket number, supplier, scrap type, total amount, net weight, and creation time recorded item by item, and goods ticket approval and logistics tracking can be handled, with new creation, import, and export supported. The top of the homepage summarizes in real time the total number of goods tickets, total amount, settled and unsettled amounts, making it clear at a glance how much has been received, how much has been settled, and how much is still owed.
This step turns "the goods were really received" from a verbal confirmation by the warehouse staff into a formal record in the system with time, quantity, and status—it is precisely the foundation of the "business flow" among the five flows, and also the prerequisite for subsequent invoices and ledgers to correspond one-to-one.

▍One-click reverse invoicing: input VAT invoices in hand immediately, with complete source files
Once the cargo document is confirmed correct, it reaches the most critical "invoice supplementation" stage. Multiple pending cargo documents can be selected for batch automatic issuance, with the electronic tax bureau interface called without login throughout the process, and invoice status flows in real time among pending, issuing, and issued. For every invoice issued, the PDF, OFD, and XML source files are retained together, and the full context is written on the invoice.
For scrap collection stations, this means the input that was always missing can now be filled in one by one, in real time and compliantly, according to goods orders. Output has invoices, input also has invoices, input and output can finally be reconciled, and profits are no longer unilaterally consumed by the tax burden of "output without input."

▍Five-flow integrated operational ledger management: five lines twisted into one rope
Having an invoice alone is not enough. To make input VAT stand up to scrutiny and ensure accounts truly match reality, the key lies in the complete approach of "reverse invoicing, integrated five-flow business ledger management"—automatically consolidating evidence scattered across each stage into one ledger built around each reverse invoice. Kailing has turned the "three-flow integration" required by policy into a more complete "five-flow integration": self-certification flow, contract flow, business flow, tax flow, and capital flow—not one is missing.

After the five flows are collected, the ledger automatically checks evidence completeness around each reverse invoice: the individual, contract, goods order, and funds are checked item by item, complete ones are marked "Five Flows Complete (5/5)", gaps are directly marked in red with a prompt of "how many items are missing", and you can check "only view missing items" to prioritize completion, and click "view star-chain diagram" to trace back along the evidence chain. Which invoice has incomplete evidence and which link is missing can be seen at a glance and filled in on the spot.

"Invoices solve "whether there is input tax"; the five-flow integrated ledger solves "whether this input tax matches the business"—the former fills gaps, the latter proves authenticity. |
At this step, the closed loop is truly established: a reverse invoice can be traced forward to a contract, a goods note, and a real receipt, and backward to a bank-enterprise direct connection payment, with input items corresponding one-to-one with business, accounts matching reality, and a closed input loop. Scrap collection stations dare to collect and operate, and dare to scale up, precisely relying on this "reverse invoicing, five-flow integrated ledger management for operations" that makes every transaction truly verifiable.
