[Direct answer]In the Beijing area, the preparation of evidence for lawsuits involving accounts receivable should focus on establishing a complete chain of evidence around four key stages: the establishment of a contractual relationship, the actual delivery of goods, the confirmation of payment settlements, and the maturity of payment obligations. The contractual stage includes purchase contracts, framework agreements, orders, and amendment orders; the delivery stage includes delivery notes, receipt notes, transportation documents, acceptance records, and warehouse entry and exit vouchers; the settlement stage includes reconciliation statements, invoices, settlement documents, and confirmation records from both parties; and the maturity stage includes payment reminders, email and chat records, statements promising repayment, and records of partial payments. Article 509 of the Civil Code of the People's Republic of China (effective January 1, 2021) stipulates that parties shall fully perform their obligations in accordance with the agreement; Article 577 stipulates that a party that fails to perform its contractual obligations or performs them in a manner inconsistent with the agreement shall bear breach of contract liability. In practice, the most common gaps occur in the delivery and settlement stages, especially when there are no receipt notes or the other party fails to confirm the reconciliation for a long time. In such cases, it is necessary to use other evidence to corroborate the facts.Creditor's rights and debts, and enforcementThe accounts receivable service in the column can assist in organizing the system.

I. Problem Background and Typical Scenarios

Common receivables dilemmas include: long-term cooperation without a written contract, only orders and delivery notes; delayed payment reconciliation, with unclear booked amounts; the other party refusing to pay on the grounds of quality but unable to provide evidence; missing receipt certificates for delivered goods; funds being deposited into personal accounts, leading to confusion about the entity involved; and disputes over the nature of partial payments and the order of offsetting debts.Business and contract disputes in enterprisesThe analysis of contract performance and breach of contract in the column can be used for reference.

III. Professional analysis by Henglue Law Firm

When handling accounts receivable cases, Henglue Lawyers typically proceed with three tasks. First, they reconstruct the transaction chain by arranging the order placement, delivery, acceptance, reconciliation, and payment processes in chronological order, identifying the evidence-deficient links and strengthening them accordingly. For example, they supplement the delivery proof by reviewing logistics information, the consignee's signature records, or on-site photos. Second, they secure the settlement basis. Even in the absence of formal reconciliation statements, they can infer the settlement amount through the parties' email exchanges, reconciliation communication records, invoice issuance records, and the amounts and timing of subsequent partial payments, as payment actions often constitute an acknowledgment of the debt amount. Third, they design traceable collection procedures. By regularly sending collection notices with confirmation requests and preserving delivery evidence, they can both interrupt the statute of limitations and establish records demonstrating the debtor's acknowledgment of the debt. It should be noted that the collection content should be specific to the amount and payment period to avoid using expressions that could be interpreted as general claims.Special services and other casesThe program-related instructions in the column can be used as supplementary information.

5. Henglu Law Firm's Reminder

First, all four links in the chain of evidence are indispensable, especially the delivery link, which is most easily overlooked. Second, the reconciliation records are the most powerful evidence for determining the amount, and a regular reconciliation mechanism should be established in daily work. Third, the payment behavior constitutes an acknowledgement of the debt, which is a common but overlooked favorable evidence. Fourth, attention should be paid to the statute of limitations, and keeping records of collection efforts can interrupt the statute of limitations. Fifth, the qualifications of the parties involved should be verified in advance to avoid suing the wrong person. Sixth, completing the evidence sorting before suing can significantly improve the efficiency of the trial.\nFinancial capital and cross-border transactions involving foreign entitiesThe fund verification approach in the column can be used for reference.

VI. Frequently Asked Questions

Q1: If there's no contract but only a delivery note, can I sue to recover the payment for the goods?

You can file a lawsuit, but you need to provide additional evidence. The delivery note can prove the delivery of the goods. If it specifies the product name, quantity, unit price, and the consignee's signature, it can often be inferred that a sales relationship exists based on the transactional practices. It is recommended to also collect order records, quotations, communication records, invoice issuance records, and some payment receipts to corroborate the transactional practices. In practice, the court will comprehensively judge based on the completeness of the delivery note and the parties' previous transaction methods. Therefore, the standardization of the documents and the completeness of the signatures are very important. Any missing parts should be supplemented with other evidence as soon as possible.

Q2: The other party keeps failing to reconcile the accounts. How can we determine the exact amount?

It can be inferred through various indirect evidences: first, the parties' recognition of the amount in their email and chat records; second, the amount of the invoice issued; third, the amount and timing of partial payments, as payments are usually made according to the settlement amount; fourth, calculating the total amount based on the number of logistics and signatures and the unit price; fifth, applying to the court for investigation and evidence collection or conducting a judicial audit when necessary. In practice, it is recommended to fix the communication records beforehand to avoid having to claim only the delivered part and give up the remaining payments due to the lack of settlement basis in litigation.

Q3: If the other party says they won't pay because of quality issues, how should I respond?

It is necessary to distinguish the burden of proof. Quality objections should generally be borne by the party who raises them, who needs to prove the existence of quality problems and the specific losses caused by them. The response methods are: first, review the provisions of the contract regarding acceptance and the time limit for objections; second, require the other party to provide inspection reports and evidence of losses; third, submit documents that meet the agreed quality standards to prove that the delivery is qualified; fourth, apply for quality appraisal if necessary. It should be noted that if the party claiming a quality defense fails to raise objections for a long time and has actually used the goods, the court may not support its defense.

Q4: I only have partial payment records. How should I calculate the balance?

First, we need to determine the total settlement amount, then deduct the paid amounts item by item, and clarify the order and nature of the offsets. Common disputes in practice include: whether the paid amounts are principal or interest, whether to offset interest first or principal first, and whether there is a quality deposit or a refund discount. It is recommended to prepare a written reconciliation statement, listing the time, amount, and payer's remarks for each payment, and marking the items offset. If the other party has provided a written confirmation of the balance or indicated the payment as a settlement when making a partial payment, this confirmation is often the most powerful evidence.

Q5: Is it necessary to send a pre-litigation reminder to collect the debt and leave evidence before suing someone?

It is recommended to do this, and it should be specific. Collection records can interrupt the statute of limitations, and the other party's response often constitutes an acknowledgment of the debt. An effective approach is to regularly send collection letters or information stating the contract number, shipment batch, settlement amount, and payment deadline, and keep the delivery receipts; if the other party replies to confirm the amount or promises to pay, the reply should be fixed in a timely manner. It should be noted that it is necessary to avoid using expressions that may be interpreted as waiving rights or making only general claims, ensuring that each collection document clearly refers to a specific claim.Creditor's rights and debts, and enforcementThe column can also provide an explanation of the subsequent implementation path.
