Tax governance by data, media-free invoicing, and dynamic credit limits — without connecting business, finance, and tax systems, costs will instead be higher than in the paper era
E-Tax Bureau + real-name authentication login for invoicing, cancellation of invoice codes, 20-digit number-based code assignment management, with no limit on the number of invoices or per-invoice amount.
The system dynamically assigns a total invoicing limit based on operations, invoicing, invoice receipt, and filing behavior. Failure to monitor in real time may block invoicing at any time.
Business, finance, tax, and funds systems are not connected, and in the fully digitalized e-invoice era the costs of organization, reconciliation, and archiving are actually higher.
Fully digitalized e-invoices must retain three formats—PDF, OFD, and XML—and cannot be archived as photographed images, otherwise penalties may be incurred.
Leqi Direct Connection, fully digitalized e-invoice interfaces, Electronic Tax Bureau — different scales and different daily invoicing volumes each have their optimal solution

Suitable for leading large and medium-sized groups and state-owned enterprises with a daily invoicing volume of more than 1,000 invoices.

From contract collection to e-commerce platforms, from document splitting and merging to export tax rebates, invoices are issued according to how the business occurs
Sales contract—invoicing—payment collection—bookkeeping—archiving connected in one line, with payment collection status automatically updating the invoicing list.
Integrate with mainstream office approval systems; invoice issuance is triggered as soon as the application form is routed, with review, scanning, express delivery, and delivery all online.
Financial and business systems such as Yonyou, Kingdee, Inspur, and Digiwin enable automatic invoicing from sales orders and delivery notes.
In-house applications, mini-programs, mall websites, and business middle platforms; platform self-operated sales automatically issue invoices externally.
The matched transaction platform provides invoicing capability for onboarded merchants; third-party merchants, as the seller, are the invoicing party.

Connect to the electronic port, bring in custom remarks, issue invoices that meet export requirements, and support tax rebate operations.
Store staff generate an invoicing QR code, and customers scan it to fill in and issue; payment triggers invoicing, and the invoice is generated synchronously when the transaction is completed.
Direct connection to finance, office, and e-commerce systems — wherever business happens, invoices are automatically issued there
