Terms of Service
1. Definitions
1.1 Merchant ID. The account you use to sign in to and operate the merchant console. KBLL emails the initial credentials to the contact address you provide.
1.2 Merchant Key. The API secret bound to a Merchant ID and used to authorise API calls.
1.3 Settlement. The process by which KBLL credits funds collected from buyers to your merchant balance within the agreed settlement window and disburses them to your nominated bank account.
1.4 Withdrawal. A funds-transfer instruction you submit (or that is created by an agreed settlement rule) for KBLL to move funds from your merchant balance to your bank account.
2. Service Scope
2.1 What the service does. KBLL provides aggregated payment acceptance — including WAP, H5, QR, native SDK and on-chain USDT (TRC20) — together with reconciliation, settlement, risk and merchant-management tools.
2.2 Limits. The service may only be used for goods or services that have been declared and approved on the merchant console. Each transaction is subject to platform limits. KBLL may adjust your transaction limits based on your business category and risk profile.
3. Rights and Duties of KBLL
3.1 Operate, maintain and secure the payment systems.
3.2 Provide order/transaction lookup APIs and reconciliation files.
3.3 Validate payment instructions using your merchant credentials. Once your credentials are validated, the instruction is treated as authorised.
3.4 Disputes between you and your end users are your responsibility, except those caused by faults attributable to KBLL.
3.5 Audit your business periodically. We may suspend or terminate service if you fall outside the scope agreed in §2.2 or breach applicable laws.
3.6 Suspend or terminate dormant accounts (no activity for 6 / 12 months) and require re-verification.
3.7 Delayed settlement. If we detect possible money-laundering, fraud, card-not-present cash-out, or other suspicious activity, we may delay settlement of the affected transactions until the matter is resolved. You are liable to indemnify us for losses caused by your acts or omissions.
3.8 Identity and authorisation. By using the service you authorise us to collect, store and use information generated during your use of the service, including your and your legal representatives' identity, account and transaction information, and to share such information with competent authorities or financial-services partners for identity verification and review.
3.9 Risk control. We continuously monitor amounts, counts, types, timing, frequency and channels of transactions, and may delay settlement, lower limits, freeze cards or revoke privileges where anomalies are detected.
4. Your Rights and Duties
4.1 Onboarding. You must provide accurate, truthful and complete information when opening your merchant account, and notify us in advance if any of it changes (address, ownership, domain, contact, etc.). If you fail to do so we may suspend service.
4.2 Account use. You may not lease, transfer or assign your merchant account, API keys or certificates. You may not pass other merchants' transactions through your account.
4.3 No storage of sensitive cardholder data. You must not store cardholder PAN, expiry date, CVV, magnetic stripe data, chip data or PIN. You must never expose card or borrowed-card information.
4.4 Account security. Keep your merchant ID, password, SMS OTP and API key safe. Every action under your merchant account is deemed your action. If credentials are compromised, contact support and request suspension immediately. Losses caused by your negligence are your responsibility.
4.5 Finality of instructions. Once executed by KBLL, payment instructions are irrevocable.
4.6 Brand use. Do not copy, modify, intercept or counterfeit KBLL's trademarks, logos or assets. Do not display links or content related to KBLL on pages other than your registered domain without our written authorisation.
4.7 Security and maintenance. You are responsible for the hardware platform, network costs and integrity of your systems. You must verify request/response signatures in every transaction and handle anomalies promptly.
4.8 Real transactions only. You warrant that transactions arise from genuine sales of declared goods or services; no test wash, fictitious or self-dealing transactions.
4.9 Records. Keep order data (user identifier, product, amount, settlement price, delivery info) and supporting documents for at least three years from the date of each transaction or termination of this agreement, and provide them within two business days of our request.
4.10 Sub-merchants on third-party marketplaces. If you operate a marketplace, you must KYC each sub-merchant, retain their credentials, transmit their transaction details to us, and accept responsibility for their compliance.
4.11 Risk control over sub-merchants. You must prevent sub-merchants from using the service for card cash-out, money-laundering or fictitious trading and bear breach-of-contract liability if they do.
4.12 AML. No assistance to cardholders in card cash-out, money-laundering or transaction splitting. We may suspend service and report you to the People's Bank of China, the police and relevant supervisors if you breach this clause.
4.13 Separate accounts for physical and virtual. If you sell both, you must apply for separate merchant accounts for each category.
4.14 Security. Do not reverse-engineer or tamper with KBLL's software, signatures, runtime data or server data.
4.15 Consumer protection. Protect consumer rights; do not discriminate between consumers based on the payment method they choose.

- Do not use receipts, settlement slips, business-receipt cards or terminals for any purpose outside the scope of this agreement, and do not authorise third parties to do so.
- Do not entrust or transfer KBLL's APIs to third parties.
- Do not employ collectors who lack a valid identity document.
- Higher-risk merchants (gold, jewellery, watches, precious metals, etc.) must install video monitoring and retain footage for at least three months.
- Verify the cardholder's identity (passport / ID) for any single transaction exceeding RMB 50,000 equivalent.
- Accept KBLL's service on the agreed schedule and do not unilaterally refuse it during the term.
- Do not raise transactions for other merchants; do not lease or assign receipt terminals or settlement bank accounts.
- Do not request other merchants to raise transactions on your behalf; do not use leased terminals or bank accounts.
- Maintain transaction records carefully and restrict access to authorised personnel.
- Do not charge consumers any surcharge or extra fee for using a particular method, and do not provide a sub-standard service to such users.
4.17 Equal treatment. Users of every payment method you support must receive identical service. You may not refuse a method already enabled on your account without good reason.
5. Fees and Settlement
5.1 Processing fee. KBLL deducts a processing fee from each transaction at the rate recorded on the merchant console. Promotional rates may apply for a limited time; the rate reverts to the standard rate when the promotion ends.
5.2 Rounding to the nearest two decimal places is accepted by both parties.
5.3 Settlement.
5.3.1 After deducting fees, the remaining amount is credited to your KBLL balance.
5.3.2 Your nominated withdrawal account must match the legal owner of your merchant account. We are not liable for failed disbursements caused by your or the bank's information.
5.3.3 To change the withdrawal account, sign a supplemental agreement or self-service in the merchant console. Extra costs from late notifications are on you.
5.3.4 For T-day transactions, settlement happens after fees are deducted and within the schedule recorded on the merchant console.
5.3.5 You may request a change to settlement rules via the merchant console / customer service; the rule of record applies.
5.3.6 If your account is less than 90 days old or you go 90 days without transactions, T+0 settlement is unavailable; we settle in T mode and you may not draw against unsettled funds. We may adjust the cycle based on your business and actual repayment behaviour with notice by email.
5.3.7 If your books disagree with ours, our records prevail.
5.3.8 If you need invoices, submit accurate billing information before issuing. We issue VAT receipts monthly for the processing fee. Special invoices require additional materials.
6. Risk Deposit
6.1 We may require you to post a risk deposit. The deposit is frozen for the duration of this agreement and may not be advanced, withdrawn or used by you.
6.2 We may adjust the required deposit and notify you by email. If you fail to top up within five business days of notice, we may suspend service. If you fail to top up within thirty days of notice, we may terminate this agreement unilaterally.
6.3 If, after one year of dormancy and without complaints or disputes, you actively close your account, the deposit principal is refunded to you. Before that you have no right to use the principal; once the deposit is refunded no interest is payable.
6.4 If you breach any law, regulation, policy or this agreement and cause loss to a user or to us, we may use the deposit to indemnify them or us; any shortfall may be deducted from your pending settlements and pursued further.
7. Refunds
7.1 You must keep enough balance in your account to cover the refund. Refunds are deducted directly from your balance. Failed refunds caused by insufficient balance are your responsibility. If a refund initiated by us fails for bank or user reasons, the amount returns to your balance and you may retry.
7.2 We do not charge a fee for refunds, but if the acquiring bank charges us, we may pass that fee through to you after advancing it.
7.3 You are responsible for resolving disputes that lead to refunds.
8. Confidentiality
8.1 Except as agreed in this contract, neither party may disclose its content, user personal data, payment information, technical interfaces or security certificates without written consent.
8.2 The parties protect each other's trade secrets. We may disclose your commercial information only when required to do so by the PBoC, CBIRC, CSRC, police, courts or prosecutors, or when validating a confirmed user complaint.
8.3 Each party ensures employees and agents respect this confidentiality clause.
8.4 Confidentiality survives termination by five years.
9. Breach
9.1 Any breach is a violation of contract.
9.2 We may terminate this agreement unilaterally and seek indemnification if you:
- directly or indirectly participate in fraud or any activity involving counterfeit bank accounts, cards or payment instruments;
- are listed as a "severely dishonest enterprise" by the national credit-information system, or your registered address is fake;
- or your legal representative are blacklisted by China UnionPay, card networks or other supervisory bodies;
- operate in breach of this agreement, the KBLL service rules or the WeChat / public-platform service terms, and refuse to remedy after notice;
- refuse a transaction lookup, reconciliation enquiry or oversight request without reason;
- tamper with our software, signatures or accounts;
- damage KBLL's or Tencent's interests;
- use the service for any illegal activity;
- fail to fix security issues in your systems after notice;
- are involved in events that we judge to be transaction anomalies;
- otherwise breach KBLL's rules.
10. Account Closure
10.1 We may close your merchant account, except as otherwise required by law or this agreement, if (1) you request closure, (2) this agreement is terminated, (3) you use the service for unlawful activity, or (4) you violate this or any other agreement signed with us.
10.2 Whether or not your account is closed, we may freeze or deduct funds from your account to comply with valid legal or regulatory orders.
11. Force Majeure
11.1 Neither party is liable for failure caused by force majeure (events beyond reasonable foresight, avoidance and control). Given the nature of the internet, this includes hacking, virus attacks, system damage or downtime, regulatory action by telecom operators or government, and other non-attributable causes.
11.2 The party affected must notify the other in writing and the parties will decide whether to continue performance based on the impact of the event.
12. Risk Notices and Special Provisions
12.1 The parties acknowledge that China's domestic e-commerce environment is still maturing and the legal and credit infrastructure is incomplete; both parties take reasonable preventive measures to minimise risk.
12.2 Cardholder repudiation. During the service, you should actively guard against repudiation by cardholders and resolve disputes promptly.
- If a transaction involves fraud, fake invoices, leaked cardholder data or breach of law or contract, you bear the loss in full.
- If a transaction shows characteristics of cardholder repudiation, splitting or wash trades, you must provide supporting documents under §4.8 and §4.9. If you fail to provide them or stop processing further suspicious transactions after written notice, all resulting losses are on you.
Losses caused to KBLL. We may deduct the equivalent amount from your risk deposit; you must top it up promptly. Where the deposit is insufficient, we may deduct from your pending settlements and continue to pursue you for the balance.
12.3 You must comply with the rules of the People's Bank of China, the card networks and other regulators. No virtual / cash-out / launder activity, no internet gambling, no pornography, no lottery, no unauthorised foreign-exchange, no virtual-currency exchange, no unlicensed wealth-management or commodity-exchange business. Otherwise we may terminate service.
12.4 Large-amount feature. Activating large-amount disbursement obliges you to use it strictly for real-name business; otherwise you indemnify users in advance and unconditionally.
13. Intellectual Property
13.1 All content provided by KBLL under this agreement (including trademarks, logos, pages, copy and images) is owned by KBLL.
13.2 Unless otherwise stated, all software, technical interfaces, security certificates and other intellectual property provided by KBLL belong to KBLL.
13.3 Without written authorisation from us or the rights holder you may not use the above intellectual property to make derivative works.
13.4 You may not facilitate the substitution, concealment, alteration, hiding or damage of items, props or terminals bearing the KBLL name, mark or logo; otherwise you must restore them and compensate us.
14. Amendment
KBLL may revise this agreement from time to time. Updates are announced on the merchant console. Continued use of the service after the announcement constitutes acceptance. If you do not accept the revisions you must notify us in writing to stop the service.
15. Governing Law and Dispute Resolution
15.1 This agreement is governed by the laws of the People's Republic of China (mainland).
15.2 Disputes shall first be resolved by friendly negotiation. If that fails, either party may submit the dispute to the People's Court with jurisdiction at KBLL's place of business.
16. Term, Automatic Renewal and Early Termination
16.1 The agreement is effective from the date confirmed on the merchant console and is open-ended by default. Where we propose a rate change and you continue to use the service for 30 days after the notice, we may apply the new rate from day 31 and deduct it from your pending settlements.
16.2 Either party may terminate this agreement for any reason with one month's written or email notice without further liability.
16.3 Confidentiality, refund and risk-deposit clauses survive termination.
16.4 This agreement is executed in two counterparts of equal legal force.
