关于付款节点与逾期款项处理的告知函

尊敬的客户及合作伙伴：

感谢您长期以来对先飞技术的信任与支持。

我们深知，任何一项商业合作的顺利完成，都离不开双方在产品、服务、交付、验收、付款等环节上的相互配合。付款安排看似只是财务事项，实质上关系到项目排期、资源投入、交付保障、售后支持以及公司内部管理秩序。

为避免因付款节点不清、内部审批延迟、沟通节奏不当而影响合作体验，现就我司关于付款提醒、逾期款项处理及相关内控流程作如下说明。本告知函不针对任何特定客户，仅用于说明我司在正常业务合作中的基本原则和处理方式。

一、付款依据

我司所有付款提醒和逾期款项处理，均以双方已经确认的合同、订单、报价单、项目确认文件、书面沟通记录、交易习惯或实际履行事实为基础。

凡双方已明确付款节点、付款条件、验收条件或交付前置条件的，我司将按照约定执行。对于未单独签署完整合同但已形成实际交易关系的项目，我司也将依据双方确认的书面内容、历史交易记录、项目交付事实及公司规范进行处理。

我司不会在缺乏依据的情况下随意催款，也不会将正常的付款提醒理解为对客户的不信任。付款提醒的目的，是为了帮助双方更顺畅地完成项目流程，避免因时间节点遗漏而造成不必要的误会。

二、基本立场

我司始终认为，付款问题首先是商业协作问题，其次才是款项追索问题。

在合作过程中，客户可能存在内部审批流程、资金排期、项目验收、发票流转、付款权限等客观安排。我司对此保持理解，也愿意在合理范围内配合客户完成必要的流程衔接。

同时，也请客户理解，我司内部同样存在项目排期、成本支出、人员安排、供应链付款、税务合规、账务核算和内控审查等管理要求。任何款项长期未能按约定支付，都会给我司项目管理和内部合规带来实际压力。

因此，我司希望双方能够在尊重合同、尊重事实、尊重彼此流程的基础上，及时沟通、及时确认、及时履行，避免将原本可以友好解决的付款事项推进到正式催告、法务介入或司法程序阶段。

三、付款提醒与逾期处理的区别

付款到期日前的沟通，属于付款节点提醒；付款到期后的沟通，属于逾期款项处理。二者性质不同，处理方式也不同。

对于尚未到期或即将到期的款项，我司通常会以温和、礼貌、提醒式的方式进行沟通。此类提醒并非催债，也并非施压，而是为了协助客户提前安排内部付款流程，避免因审批、排期、发票、资料或负责人不在岗等原因导致付款延误。

在项目服务过程中，我司相关成员也可能结合发货、验收、售后、技术支持、项目排期等事项，与客户同步付款节点。此类沟通属于正常项目管理的一部分，目的是让双方流程更加清晰，而不是制造对立。

四、逾期款项处理节点

如款项超过约定期限仍未支付，我司将根据合同约定、逾期天数、客户沟通情况、项目履行情况及内部合规要求，逐步启动相应处理流程。

以下节点一般自双方约定的付款到期日次日起算。特殊项目、特殊合同或双方另有书面约定的，从其约定执行。

（一）逾期 7 天内：付款提醒与情况确认

款项到期后 7 天内，我司通常会先通过项目对接人员、商务人员或相关负责人成员进行付款提醒，并同步确认是否存在发票、验收、资料、审批、付款排期等客观问题。

该阶段以沟通、确认和协助推进为主，目的不是制造压力，而是帮助双方尽快排除流程障碍，避免小问题演变成正式逾期事项。

如客户能够明确付款时间，并积极配合完成相关流程，我司原则上仍以友好沟通方式处理。

（二）逾期满 7 天：启动正式催款流程

如款项逾期满 7 天后仍未支付，且客户未能提出明确、合理、可执行的付款安排，我司将根据内部流程启动正式催款程序。

该阶段，我司可能出具书面付款提醒函、付款申请函或催款函，并对相关项目进行内部预警。必要时，我司可能根据合同约定，对后续交付、出库、技术支持、售后服务、项目排期等事项作出相应调整。

该流程并非针对客户个人，也不代表双方关系必然恶化，而是我司基于合同履行、内部控制和项目风险管理所必须采取的正常措施。

（三）逾期满 30 天：列为严重逾期事项

如款项逾期满 30 天仍未支付，原则上将被列为严重逾期事项。

进入该阶段后，我司将不再仅按一般项目沟通处理，而会将相关事项提交至公司内控、法务或外部专业机构进行评估。根据具体情况，我司可能采取包括但不限于以下措施：

1. 发出正式盖章催款函；

2. 要求客户出具明确的付款计划或书面说明；

3. 暂停或限制未完成付款条件所对应的后续服务；

4. 重新评估客户信用等级、合作条件及后续账期安排；

5. 视情况安排律师函、法务函或其他正式法律文件。

我司希望客户理解，逾期超过 30 天后，事项性质已经不再只是普通付款提醒，而是进入公司正式风险管理范围。此时继续拖延、沉默或反复失约，将可能导致处理程序进一步升级。

（四）逾期满 90 天：原则上启动司法处理程序

如款项逾期满 90 天仍未支付，且客户未能提供合理解释、有效担保或明确可执行的付款安排，我司原则上将启动司法处理程序。

司法处理方式包括但不限于诉讼、仲裁、财产保全、违约责任追究、律师费用及其他实现债权费用的主张等。具体措施将依据双方合同约定、交易事实、欠款金额、客户沟通情况及证据材料综合确定。

我司并不希望任何合作事项发展至司法程序。诉讼或仲裁并非我司优先选择，但当常规沟通、书面催告和法务沟通均无法解决问题时，依法处理就是企业维护合法权益和内部管理秩序的必要方式。

五、关于服务、交付与付款节点的关系

对于分阶段交付、定制化开发、设备出库、技术支持、售后服务、现场服务等项目，付款节点通常与项目进度、资源投入和交付安排相互关联。

如客户未按约定履行付款义务，我司可能根据合同约定及项目实际情况，暂停或调整后续交付、出库、技术支持、售后响应、项目排期或其他相关服务安排。

该等处理并非对客户进行惩罚，而是为了避免在付款条件尚未满足的情况下继续扩大项目风险。我们也希望客户在安排付款时充分考虑上述影响，以免影响项目整体进度和后续合作体验。

六、关于客户沟通与相互尊重

我司要求内部成员在付款提醒和逾期沟通过程中，保持专业、克制、礼貌和有温度的沟通方式。

付款逾期并不意味着双方关系必然对立。客户有客户的流程，我司也有我司的管理要求。我们希望相关沟通能够建立在事实、合同和相互尊重的基础上，避免使用情绪化、羞辱性、威胁性或不必要激化矛盾的表达。

同时，我们也希望客户能够理解，付款义务是商业合作中最基本的履约内容之一。及时付款不仅体现信用，也有助于保障后续服务质量、项目资源投入和长期合作关系。

七、特殊情形说明

上述节点为我司一般内控处理规则，不排除根据具体情况提前或延后采取相应措施。

如客户存在恶意拖欠、拒绝沟通、转移财产、虚假承诺、反复失约、明显逃避债务或其他可能扩大损失的情形，我司有权根据实际情况提前启动法务或司法程序。

如客户能够保持积极沟通，并提出合理、明确、可执行的付款方案，我司也可以根据项目情况、历史合作情况和内部审批结果，给予必要的沟通空间。

我司设置上述节点的目的，不是为了扩大矛盾，而是为了让付款事项有清晰边界，让双方都能够提前预判后续流程，避免因拖延、误解或侥幸心理导致更大的合作成本。

八、客户协作建议

为避免因付款延迟影响合作进度，建议客户在收到合同、订单、发票或付款提醒后，及时完成以下事项：

1. 核对付款金额、付款节点、收款账户和发票信息；

2. 提前安排内部审批、付款排期和负责人确认；

3. 如存在验收、资料、发票或流程问题，请及时向我司对接人员反馈；

4. 如确有短期资金安排困难，请尽早沟通，并提出明确、可执行的付款计划；

5. 避免长期沉默、反复失约或无明确时间安排，以免触发我司内部升级流程。

九、守约方能长久

我们始终相信，好的合作关系不仅建立在产品和服务之上，也建立在彼此守约、相互理解和及时沟通之上。

付款提醒不是对抗，逾期处理也不是我司希望优先采取的方式。我们更愿意通过清晰的节点、友好的沟通和专业的流程，帮助双方把合作事项处理得体面、顺畅、可持续。

如您对付款安排、发票信息、项目节点或我司相关流程存在疑问，欢迎及时联系我司对接人员。我们愿意在合理范围内积极协助，共同推动项目顺利完成。

Notice Regarding Payment Milestones and Handling of Overdue Payments

Dear Customers and Partners,

Thank you for your long-standing trust and support in ALLXF.

We understand that the successful completion of any business collaboration depends on mutual cooperation between both parties across product, service, delivery, acceptance, and payment. Payment arrangements may appear to be merely financial matters, but they in fact affect project scheduling, resource allocation, delivery assurance, after-sales support, and internal management order.

To avoid impacts on the cooperation experience caused by unclear payment milestones, delayed internal approvals, or improper communication rhythms, we hereby set out our policies on payment reminders, overdue payment handling, and related internal control procedures. This notice is not directed at any specific customer; it serves only to clarify the basic principles and handling methods we apply in normal business cooperation.

I. Basis for Payment

All payment reminders and overdue payment handling by our company are based on contracts, orders, quotations, project confirmation documents, written communication records, established transaction practices, or actual performance facts that have been confirmed by both parties.

Where payment milestones, payment conditions, acceptance conditions, or delivery prerequisites have been clearly defined by both parties, we will enforce them in accordance with the agreement. For projects where a complete contract has not been separately signed but an actual transaction relationship has been established, we will also handle matters based on written content confirmed by both parties, historical transaction records, project delivery facts, and company regulations.

We will not issue payment reminders without basis, nor will we interpret routine payment reminders as a lack of trust in our customers. The purpose of payment reminders is to help both parties complete project processes more smoothly and to avoid unnecessary misunderstandings caused by overlooked deadlines.

II. Basic Position

We have always held that payment issues are first and foremost matters of business collaboration, and only secondarily matters of payment recovery.

During cooperation, customers may face objective arrangements such as internal approval processes, fund scheduling, project acceptance, invoice circulation, and payment authority. We understand this and are willing to cooperate with customers within reasonable limits to complete necessary process coordination.

At the same time, we ask that customers understand our company also has internal management requirements, including project scheduling, cost expenditure, staffing, supply chain payments, tax compliance, accounting reconciliation, and internal control reviews. Any payment that remains outstanding beyond the agreed period creates real pressure on our project management and internal compliance.

Therefore, we hope both parties can communicate promptly, confirm promptly, and perform promptly on the basis of respecting the contract, respecting the facts, and respecting each other's processes — so as to avoid escalating what could otherwise be amicably resolved payment matters into formal demands, legal involvement, or judicial proceedings.

III. Distinction Between Payment Reminders and Overdue Payment Handling

Communication before a payment due date constitutes a payment milestone reminder; communication after a payment due date constitutes overdue payment handling. The two differ in nature and in handling approach.

For payments that are not yet due or are approaching their due date, we typically communicate in a gentle, courteous, and reminder-oriented manner. Such reminders are neither debt collection nor pressure — they are intended to assist customers in arranging internal payment processes in advance, so as to avoid payment delays caused by approvals, scheduling, invoices, documentation, or the absence of responsible personnel.

During project service delivery, our team members may also synchronize payment milestones with customers in connection with shipment, acceptance, after-sales service, technical support, or project scheduling. Such communication is a normal part of project management, intended to make both parties' processes clearer — not to create adversarial dynamics.

IV. Overdue Payment Handling Milestones

If a payment remains outstanding beyond the agreed deadline, we will gradually initiate corresponding handling procedures based on the contract terms, the number of overdue days, customer communication status, project performance status, and internal compliance requirements.

The following milestones are generally calculated from the day following the agreed payment due date. For special projects, special contracts, or cases where both parties have agreed otherwise in writing, those agreements shall prevail.

(1) Within 7 Days of Overdue: Payment Reminder and Status Confirmation

Within 7 days after the due date, we will typically first issue a payment reminder through the project contact, business personnel, or relevant responsible parties, while simultaneously confirming whether there are any objective issues such as invoices, acceptance, documentation, approvals, or payment scheduling.

This stage focuses on communication, confirmation, and facilitation — not on creating pressure. The goal is to help both parties promptly remove process obstacles and prevent minor issues from becoming formal overdue matters.

If the customer can specify a payment date and actively cooperate to complete relevant processes, we will in principle continue to handle the matter through friendly communication.

(2) 7 Days Overdue: Initiation of Formal Collection Process

If the payment remains unpaid after 7 days of overdue status, and the customer has not proposed a clear, reasonable, and executable payment arrangement, we will initiate a formal collection procedure in accordance with our internal processes.

At this stage, we may issue a written payment reminder letter, payment request letter, or collection letter, and trigger an internal alert for the relevant project. Where necessary, we may adjust subsequent delivery, warehousing release, technical support, after-sales service, project scheduling, or other matters in accordance with the contract.

This process is not directed at any individual customer, nor does it indicate that the relationship between both parties has necessarily deteriorated. It is a normal measure we must take based on contract performance, internal control, and project risk management.

(3) 30 Days Overdue: Classified as Serious Overdue Matter

If the payment remains unpaid after 30 days of overdue status, it will in principle be classified as a serious overdue matter.

At this stage, we will no longer handle the matter through general project communication alone. Instead, we will submit the relevant matter to our internal control, legal, or external professional agencies for assessment. Depending on the specific circumstances, we may take measures including but not limited to:

• Issuing a formal collection letter with company seal;

• Requesting the customer to provide a clear payment plan or written explanation;

• Suspending or restricting subsequent services corresponding to unfulfilled payment conditions;

• Re-evaluating the customer's credit rating, cooperation terms, and future credit period arrangements;

• Arranging a lawyer's letter, legal notice, or other formal legal documents as appropriate.

We ask customers to understand that after 30 days of overdue status, the nature of the matter is no longer a routine payment reminder — it has entered the scope of formal company risk management. Continued delay, silence, or repeated failure to honor commitments at this point may lead to further escalation of handling procedures.

(4) 90 Days Overdue: Judicial Proceedings Initiated in Principle

If the payment remains unpaid after 90 days of overdue status, and the customer has not provided a reasonable explanation, effective guarantee, or a clear and executable payment arrangement, we will in principle initiate judicial proceedings.

Judicial measures include but are not limited to litigation, arbitration, property preservation, pursuit of liability for breach of contract, claims for legal fees and other costs of realizing creditor's rights. Specific measures will be determined based on the contract terms between both parties, transaction facts, outstanding amount, customer communication status, and available evidence.

We do not wish for any cooperation matter to reach judicial proceedings. Litigation or arbitration is not our preferred option. However, when routine communication, written demands, and legal consultations all fail to resolve the issue, legal action becomes the necessary means for an enterprise to protect its legitimate rights and maintain internal management order.

V. Relationship Between Service, Delivery, and Payment Milestones

For projects involving phased delivery, customized development, equipment release, technical support, after-sales service, or on-site service, payment milestones are typically interlinked with project progress, resource investment, and delivery arrangements.

If a customer fails to fulfill payment obligations as agreed, we may, in accordance with the contract and actual project conditions, suspend or adjust subsequent delivery, warehousing release, technical support, after-sales response, project scheduling, or other related service arrangements.

Such measures are not intended as punishment of the customer, but rather to avoid expanding project risk while payment conditions remain unmet. We also hope that customers will take these impacts into account when arranging payments, so as not to affect overall project progress and the experience of future cooperation.

VI. Customer Communication and Mutual Respect

We require our internal staff to maintain a professional, restrained, courteous, and warm communication style during payment reminders and overdue payment communications.

Payment overdue status does not mean that the relationship between both parties must become adversarial. Customers have their own processes; our company has its own management requirements. We hope that all communication can be conducted on the basis of facts, contracts, and mutual respect, avoiding emotional, humiliating, threatening, or unnecessarily confrontational expressions.

At the same time, we also hope customers understand that payment obligations are among the most fundamental performance obligations in business cooperation. Timely payment not only reflects creditworthiness but also helps ensure subsequent service quality, project resource investment, and long-term cooperative relationships.

VII. Special Circumstances

The above milestones represent our general internal control rules. We do not exclude the possibility of taking corresponding measures earlier or later depending on specific circumstances.

If a customer engages in malicious non-payment, refuses to communicate, transfers assets, makes false commitments, repeatedly fails to honor agreements, obviously evades debt, or engages in other conduct that may expand losses, our company reserves the right to initiate legal or judicial proceedings in advance based on the actual situation.

If a customer maintains active communication and proposes a reasonable, clear, and executable payment plan, our company may also, depending on the project situation, historical cooperation record, and internal approval results, provide necessary room for communication.

The purpose of setting the above milestones is not to escalate conflicts, but to establish clear boundaries for payment matters so that both parties can anticipate subsequent processes in advance, and to avoid greater cooperation costs caused by delay, misunderstanding, or luck mentality.

VIII. Customer Collaboration Recommendations

To avoid payment delays affecting cooperation progress, we recommend that customers, upon receiving contracts, orders, invoices, or payment reminders, promptly complete the following:

• Verify the payment amount, payment milestone, receiving account, and invoice information;

• Arrange internal approval, payment scheduling, and responsible person confirmation in advance;

• If there are issues with acceptance, documentation, invoices, or processes, please provide timely feedback to our project contact;

• If there are indeed short-term fund scheduling difficulties, please communicate early and propose a clear, executable payment plan;

• Avoid prolonged silence, repeated failure to honor commitments, or providing no clear timeline, so as not to trigger our internal escalation process.

IX. Keeping Commitments Sustains Long-Term Partnerships

We have always believed that a good cooperative relationship is built not only on products and services, but also on mutual commitment, mutual understanding, and timely communication.

Payment reminders are not confrontation. Overdue payment handling is not what we prefer to adopt. We would rather help both parties handle cooperation matters with dignity, smoothness, and sustainability through clear milestones, friendly communication, and professional processes.

If you have any questions regarding payment arrangements, invoice information, project milestones, or our relevant processes, please feel free to contact our project contact in a timely manner. We are willing to actively assist within reasonable limits and work together to ensure the smooth completion of projects.

This notice is hereby issued.
