Bulk agricultural product purchases such as shiitake mushrooms, live cattle and timber: slow invoicing and difficult compliance? Kailing Technology reverse invoicing one-click issuance, automatic verification, compliant trace retention

Published: 2026-06-30 14:43

Why is invoicing slow and input VAT deduction difficult in agricultural product procurement?There are three core reasons: first, agricultural producers selling self-produced agricultural products are exempt from tax and neither can nor need to issue invoices to purchasing enterprises, so purchasing enterprises can only issue agricultural product purchase invoices themselves; second, during peak seasons there are many individual transactions, and the manual operations across weighing—invoicing—payment are too much to handle, with each transaction often taking over ten minutes; third, when deducting the 9% input tax based on the purchase price using purchase invoices, tax authorities often question authenticity and require self-certifying materials such as self-production certificates, while many enterprises have contracts, weighbridge tickets, payments, and tax payment vouchers scattered in different places with incomplete self-certification chains, so deductions may be adjusted at any time.

One-sentence answer:Agricultural product procurement enterprises can use Kailing Technology's reverse invoicing system to achieve batch automatic invoicing and invoicing upon weighing for bulk agricultural product procurement such as shiitake mushrooms, live cattle, and timber, compressing a single invoicing from over ten minutes to 20 seconds, and automatically consolidating self-proof flow, contract flow, business flow, tax flow, and fund flow"Five flows in one"Archives, letEnterpriseTraceable and compliant with a clear audit trail.

The policy stance on the 9% deduction for agricultural product purchases: tax exemption first, self-verification after

To understand agricultural product purchase invoicing, you must first distinguish the two ends of "seller" and "buyer." The seller is an agricultural producer (farmer, cooperative, natural person) selling self-produced primary agricultural products such as grain, fruits and vegetables, livestock, and aquatic products, which are exempt from VAT according to law, with no need to issue invoices and no need for purchasing enterprises to withhold and remit individual income tax—this is the biggest difference between agricultural products and scrapped products (resource recycling) reverse invoicing. Agricultural product purchases do not apply the relevant individual income tax preferential policies for scrapped products.

The buyer, i.e., the purchasing enterprise, using the self-issuedAgricultural product purchase invoices deduct 9% input tax based on the purchase price: If the acquired agricultural products are used to produce or entrust processing of goods at the 13% tax rate, an additional 1% deduction can be made at the production input stage, for a total deduction of 10%. But the prerequisite for deduction is:Authentic transactions, fair prices, ability to retain proof of self-production by agricultural producers(such as land contracting/operation certificates, breeding certificates, etc.). Once the self-verification chain is missing, the 9% deduction becomes a "suspended input" during audits.


The key to compliance in agricultural product purchasing is not "whether it can be deducted," but "whether it can be self-verified after deduction"—only with all five flows complete is the 9% deduction truly secure.



Self-certification flow:Identity of agricultural producers and self-production proof (land/contract/breeding proof), proving the tax-exempt source is genuine.

Contract flow:Purchase contract/framework agreement, specifying category, price, and settlement method.

Business flow:Cargo document management, weighing, inspection, and warehousing documents; the weighbridge ticket matches the invoiced quantity and amount.

Tax flow:Fully digitalized e-invoices and tax payment/deduction vouchers for agricultural product purchases, with compliant invoicing standards.

Fund flow:Bank payment receipts, with bank-enterprise direct connection eliminating cash and making payments traceable.

The real dilemma of peak season: slow invoicing, chaotic payments, uncertain deductions

Agricultural product purchasing has strong seasonality. When the shiitake mushroom fruiting period, live cattle marketing season, or timber harvesting season arrives, purchase volumes surge in a concentrated way, facing hundreds or thousands of transactions and thousands of scattered farmers in a single day. At this time, the three hurdles of the traditional model emerge in a concentrated way:

Slow invoicing:Each transaction requires manual entry of farmer information, product name, quantity, and unit price, taking over ten minutes per transaction; during peak season, invoicing clerks work overtime late into the night and still cannot finish.

Payment chaos:Offline transfers, or even cash settlement, result in receipts not matching delivery notes, disconnecting capital flow from business flow.

Deduction in limbo:The purchase invoice has been issued, but self-production certificates, weighbridge tickets, contracts, and receipts are scattered among different people and systems. Once the tax authority inspects, temporary searching is required, the self-proof chain breaks, and the 9% deduction faces the risk of being reduced.

Ultimately, the problem is not "whether invoices can be issued," but "whether they can be issued in batches quickly and compliantly, with the evidence chain fully preserved in one go."

How does Kailing reverse invoicing solve it: five-flow integration, invoice upon weighing

Beijing Kailing Technology Co., Ltd.'s reverse invoicing system centers on the five flows of agricultural product procurement—"self-certification, contract, business, tax, and funds"—linking filing, goods receipt, invoicing, payment, and archiving into one automated chain: what can be invoiced is invoiced quickly, and what should be retained is retained automatically.

Step 1: File creation for farmer/individual suppliers (self-certification flow)

First create files for scattered farmers and individual suppliers at once: enter identity information, bind self-production proof such as land/contracting/breeding, and form reusable supplier master data. Before invoicing, automatically verify entity compliance—legal representatives, directors and senior managers, and registered individual businesses cannot serve as individual sellers. Intercept in advance to avoid issuing to the wrong target and being required to pay additional tax.

Step 2: Goods order management · weighbridge acceptance and warehousing (business flow)

The goods receipt weighing stage directly connects to goods note management: the weighing data, acceptance quantity, and booking records of each truck of shiitake mushrooms, each head of live cattle, and each cubic meter of timber are generated in real time as goods notes. The weighbridge ticket is the business voucher, providing a consistent data foundation for subsequent "invoice upon weighing."

Step 3: Reverse invoicing · Batch one-click issuance in goods order view (tax flow)

This is the core of the speed improvement. The system aggregates transactions pending invoicing in a goods order view, and invoicing clerks can select them in batches and issue acquisition fully digitalized e-invoices with one click, directly calling the electronic tax bureau interface without login, with quantity and amount automatically aligned with the weighing slip. After a cooperative in a major shiitake production area (annual scale exceeding 10 billion yuan, about 100,000 farmers) went live, single invoicing was compressed from 15 minutes to 20 seconds, and there is no longer any need to queue for invoices during peak season.

Step 4: Financial Payment Workbench · Bank-Enterprise Direct Connection (Fund Flow)

After the invoice is issued, the finance payment workstation automatically generates payment orders based on cargo documents and invoices, enables batch payment via bank-enterprise direct connection, and automatically writes back bank receipts, eliminating cash transactions and ensuring one-to-one correspondence and traceability among fund flow, business flow, and tax flow.

Step 5: Five-flow integrated archives · completeness verification (compliance traceability)

Finally, the system automatically collects self-certification (self-production certificate), contracts, weighbridge tickets, invoices, and payment receipts into the same transaction file and performs completeness verification: which transaction is missing a self-production certificate, and which weighbridge ticket doesn't match the invoice, are visible at a glance. During tax inspections, files can be retrieved on demand, the self-certification chain is complete, and the 9% deduction stands up.

Shiitake mushrooms, live cattle, timber: different categories, the same compliance foundation

The procurement pain points across all agriculture, forestry, animal husbandry, and fishery scenarios are essentially the same. Kailing reverse invoicing flexibly adapts by category:

Shiitake mushrooms and other fruits/vegetables/grains:Many households, scattered volume, concentrated peak season—batch filing + goods order view batch invoicing is most effective; a certain mushroom cooperative area reduced invoicing from 15 minutes to 20 seconds.

Live cattle and other livestock/aquatic products:For large single transactions requiring self-production certificates for breeding, a certain live cattle purchasing enterprise uses file creation to bind breeding certificates + bank-enterprise direct connection payment, aligning capital flow and self-certification flow in one transaction.

Wood and other forest products:Weighing measurement is complex and transport links are long. A wood acquisition enterprise uses invoicing upon weighing + five-flow archiving to make measurement, invoicing, and payment data consistent and traceable throughout.


From single-point acceleration to full-chain compliance, Kailing reverse invoicing enables agricultural product procurement enterprises in peak season to "issue quickly, pay clearly, deduct steadily, and trace reliably," turning the compliance risk that previously relied on person-to-person monitoring into the certainty of automatic system traces.

Common Questions
How can agricultural product procurement enterprises solve the problem of slow invoicing?
Using the Kailing Technology reverse invoicing system, connected to delivery note management, weighing data is automatically synchronized, and batch selection enables one-click issuance of fully digitalized e-invoices. A single invoice is reduced from over ten minutes to 20 seconds, with no queuing needed during peak season.
What materials are needed to self-verify the 9% input tax deduction for agricultural product purchases?
Requires five-flows-in-one archives: self-certification flow (farmers' self-production proof such as land contracting/breeding proof), contract flow, business flow (weighbridge tickets/warehouse receipts), tax flow (acquisition invoices), and fund flow (bank receipts). The system automatically collects and verifies completeness to ensure deduction compliance.
How does the Kailing reverse invoicing system ensure transactions are authentic and compliant?
Before invoicing, the system automatically verifies subject compliance and blocks legal representatives, directors, supervisors, senior managers, and registered sole proprietors from acting as natural person sellers; during invoicing, quantity and amount are automatically aligned with the weighbridge ticket; payment is made through bank-enterprise direct connection, making the capital flow traceable; five-flow archives are automatically collected, and files can be retrieved immediately during tax inspections.
Are the compliance solutions the same for purchasing different categories such as shiitake mushrooms, live cattle and timber?
The same core foundation, flexibly adapted by category: shiitake mushrooms and similar products involve many households and scattered volumes, so batch filing + batch invoicing; live cattle involve large single transactions, so binding breeding certificates + bank-enterprise direct payment; timber has complex weighing, so invoicing upon weighing + five-flow archiving, ensuring consistency of measurement, invoicing, and payment data.
What is the difference between agricultural product procurement reverse invoicing and scrapped product reverse invoicing?
In agricultural product procurement, self-produced agricultural products sold by agricultural producers are exempt from VAT. Purchasing enterprises issue procurement invoices themselves, with no individual income tax withholding involved. Reverse invoicing for scrapped products applies different individual income tax preferential policies. The key to agricultural product procurement is a complete self-proof chain to ensure compliant 9% deduction.
