I am the person in charge of a small and medium-sized enterprise that has just started importing electronic components. This is my first import order worth USD 100,000 handled through a proxy company, and I am about to issue the payment slip but have no experience at all. The proxy company said I need to provide contracts, invoices and customs declarations, but I am not sure if the formats of these documents are correct.

For example, does the amount on the contract have to be exactly the same as that declared on the customs declaration? Also, I heard that incorrect payment slips will cause cargo detention at the port and even affect subsequent VAT deductions. I am very anxious about delaying the delivery schedule due to mistakes. I want to know the specific steps for issuing payment slips, what details should I pay attention to, and are there any quick verification methods to avoid risks?

Pre-document examination for issuing payment slips for proxy import and export services needs to focus on three consistencies: the contract amount must match the amount declared on the customs declaration，the goods description on the invoice must match the product name corresponding to the HS code on the customs declaration，and the payment subject must match the subject agreed in the agency agreement. Among them，the "Trade Mode" field on the customs declaration must match the payment nature. For example，general trade corresponds to general payment，and processing trade with imported materials corresponds to payment for such processing，so as to avoid the bank returning the payment slip due to inconsistent fields.

For the connection of core process nodes，the operation shall be carried out in the following order: First，the proxy company shall apply to the customs for the electronic data of the payment slip of the customs declaration. The enterprise shall submit it to the bank after verifying that there is no error. After verifying the authenticity of the documents，the bank shall complete the payment through CIPS or SWIFT system. After the payment is completed，the proxy company shall feed back the payment voucher to the enterprise for subsequent tax filing and verification. The time window for key nodes must be controlled within 3 working days to avoid the invalidation of the electronic data of the customs declaration due to delay.

Emergency response plans need to be prepared in advance: If the bank feedbacks that documents are missing，immediately contact the proxy company to supplement the corresponding materials，such as certificate of origin or packing list. If the information on the payment slip is incorrect，apply to the customs to modify the customs declaration data within 24 hours and then resubmit it to the bank. Special note: When modifying the customs declaration，the original customs declaration and a statement shall be provided to avoid system errors caused by repeated submissions.

For final compliance implementation，it is necessary to ensure that the payment voucher is filed together with the customs declaration，contract and invoice，with a storage period of no less than 5 years for subsequent verification by the tax authorities and the foreign exchange administration. At the same time，the enterprise shall regularly check the payment records with the proxy company to ensure that the capital flow is consistent with the actual business and avoid compliance risks caused by unauthorized capital return.

From the perspective of customs declaration, the core basis of the payment slip is the electronic data of the customs declaration. The enterprise shall ensure that the "Importer and Exporter in China" on the customs declaration matches the name of the proxy company, and the "Consumption and Use Unit" matches the name of the actual receiving enterprise. If the "Transaction Mode" on the customs declaration is CIF, the payment amount shall include freight and insurance premiums.

If it is FOB, additional payment vouchers for freight and insurance premiums shall be provided. In addition, if there are special instructions in the "Remarks" column of the customs declaration, such as "advance payment", the corresponding advance payment ratio shall be indicated on the payment slip to avoid questions during bank review. If the data on the customs declaration is incorrect, apply to the customs for "customs declaration modification/cancellation" through the proxy company, and regenerate the electronic data of the payment slip after modification to ensure that it matches the payment information.

The operation progress of the payment slip directly affects the transfer of logistics cargo rights. If the payment slip is not submitted to the bank in time, the goods may not be cleared normally after arriving at the port, resulting in detention fees and container detention fees. The enterprise shall agree with the proxy company on the time node for submitting the payment slip, usually complete the payment 3 working days before the goods arrive at the port to ensure that there is a payment voucher when clearing customs.

If the goods are detained at the port due to delayed payment, immediately contact the logistics provider to apply for an extension of the free storage period and explain the situation to the customs to avoid additional costs. In addition, obtain the bill of lading endorsement in time after the payment is completed to ensure the smooth transfer of cargo rights to the actual receiving enterprise.

The payment slip is one of the important vouchers for enterprises to deduct import VAT. The enterprise shall ensure that the "dutiable value" on the payment slip matches the dutiable value on the customs declaration, otherwise it may affect the VAT deduction amount.

If the VAT deferral policy is adopted, the payment slip shall indicate the words "VAT deferral" and provide the corresponding deferral application voucher to avoid the tax authority requiring the payment of supplementary VAT. In addition, the payment date on the payment slip must be within 90 days after the date of issuance of the customs declaration, otherwise it may be deemed as overdue payment and affect the enterprise's tax credit rating.

From the perspective of cross-border payment and receipt compliance, the payment slip must pass the bank's authenticity verification. The enterprise shall ensure that the payment amount does not exceed the amount declared on the customs declaration by 5% (positive and negative error), otherwise a statement shall be provided.

If the payment currency is inconsistent with the currency agreed in the contract, provide an exchange rate conversion statement to ensure the accuracy of the amount. In addition, when paying through the CIPS system, fill in the correct SWIFT code and bank account number to avoid capital suspension. If capital suspension occurs, immediately contact the bank to inquire about the reason for the suspension and supplement relevant documents for settlement.

The operation of payment slips for proxy import and export shall comply with the provisions of the agency agreement. The enterprise shall clarify the responsible subject of payment, the time node for document submission and liability for breach of contract in the agency agreement to avoid losses caused by the proxy company's delayed submission of payment slips.

If the proxy company fails to complete the payment as agreed, the enterprise may require it to bear additional costs such as port detention fees according to the agreement. In addition, the electronic data of the payment slip must be consistent with the paper documents to avoid legal disputes caused by the lack of electronic data and ensure the safety of cargo rights and funds.

Although the import payment slip is not directly related to export tax rebates, the enterprise shall file the payment slip together with the import documents for the verification and investigation of the tax authorities. If the enterprise also has export business, the import payment records must match the export receipt records to avoid abnormal capital flow.

In addition, the payment subject on the payment slip must match the subject in the agency agreement, otherwise it may be deemed as "inconsistency of the four flows" and affect the handling of export tax rebates. The enterprise shall regularly audit the import payment documents to ensure compliance.
