Corporate top-up via bank transfer
Companies can top up their API balance by corporate wire transfer instead of WeChat Pay or USDT. The process:
- Email enterprise@houjiayan.com with your company name, contact, and estimated top-up amount.
- Our business team confirms the details and sends the agreement and corporate account information.
- Make the wire transfer from your corporate bank account.
- Once the payment is verified, the corresponding credits are added to your API account balance.
One entity throughout: the name on the remitting bank account, the contracting entity, and the invoice title must be the same legal entity. Transfers that do not match cannot be credited or invoiced.
Service agreement
If your company needs a signed contract, email our business team with your business license information. We support signing a service agreement before payment; the top-up and invoicing then proceed under that agreement.
Invoicing (fapiao)
For corporate bank-transfer top-ups we issue invoices under the following terms:
- Type: VAT electronic general invoice (增值税电子普通发票). Special VAT invoices (专用发票) are not supported at this time.
- Basis: invoices are issued for the consumed amount only — unused balance is not invoiced.
- Timing: 3–7 business days after request, delivered to your reserved email address.
- Invoiced amounts are non-refundable.
- Coverage: only corporate bank-transfer top-ups are invoiceable; USDT-TRC20 payments cannot be invoiced.
Invoice issuer: Inner Mongolia Huozhong Intelligent Technology Co., Ltd. (PRC Tax ID / 纳税人识别号: 91150118MAKGRFLMX8, small-scale VAT taxpayer).
