Zambia Compliance Via Digitax
Zambia Compliance Via Digitax is a tax compliance integration built on the Frappe Framework to integrate ERPNext with Zambia Tax Authority Smart Invoice System SIS through Digitax, a certified middleware provider.
The application is designed to enable businesses to automatically transmit transactional data such as sales invoices, purchase records, and item information from ERPNext to ZRA in compliance with Zambia tax regulations. It embeds compliance directly into everyday business workflows, removing the need for manual reporting.

Why This Integration Matters
The Smart Invoice System (SIS) is a mandatory system introduced by ZRA requiring businesses to generate compliant invoices and submit transaction data to the tax authority.
Without automation, this process can be time-consuming, error-prone, and difficult to maintain consistently.
By integrating ERPNext with SIS via DigiTax, businesses benefit from:
- Regulatory compliance with ZRArequirements
- Automated transmission of transaction data
- Improved accuracy in tax reporting
- Reduced manual intervention
- Better audit readiness and traceability
How It Works (High-Level)
The integration operates seamlessly within ERPNext workflows.
When a transaction such as a Sales Invoice is created, the system prepares a compliant data payload based on ZRA requirements. This data is securely sent to DigiTax through an API. DigiTax processes the request and forwards it to the SIS platform.
Once processed, a response is returned and stored in ERPNext. The transaction is then updated with compliance status and any reference details from ZRA.
This entire process happens in the background with minimal user intervention.
Key Capabilities
The application provides a full compliance layer within ERPNext, covering:
- Sales Invoice Submission: Automatic transmission of sales transactions to SIS as part of normal invoicing workflows.
- Item and Customer Registration: Synchronization of product, customer, and inventory data with SIS requirements.
- Credit/Debit Note Handling: Manage returns and adjustments in compliance with ZRA requirements

- Settings Management: Configure API credentials
Role of DigiTax
DigiTax acts as an intermediary layer between ERPNext and ZRA SIS.
It is responsible for handling secure communication with ZRA systems, validating and transforming data payloads, and ensuring adherence to ZRA API standards.
Access to SIS through DigiTax requires prior onboarding and approval.
