Zambia Compliance Via Digitax Installation Guide

Zambia Compliance via DigiTax integrates ERPNext with the Zambia Revenue Authority (ZRA) SIS platform through DigiTax, allowing tax-related transactions to be processed and transmitted automatically as part of normal ERP workflows.

The integration is designed to work in the background with minimal user intervention while ensuring that transactions remain compliant with ZRA requirements.

High-Level Flow

The integration follows a structured transaction flow between ERPNext, DigiTax, and ZRA SIS.

Step 1: Transaction Creation in ERPNext

A user creates or submits a transaction in ERPNext, such as:

• Sales Invoice
• Credit Note
• Item Registration
• Customer Registration

The application validates the transaction and checks whether it qualifies for SIS submission.

Step 2: Payload Preparation

Once the transaction is validated, the integration prepares a structured payload formatted according to DigiTax and ZRA SIS requirements.

#Step 3: Secure API Communication

The prepared payload is securely transmitted from ERPNext to DigiTax using authenticated API requests.

DigiTax acts as the middleware layer responsible for interacting with ZRA systems.

#Step 4: Processing by DigiTax and SIS

DigiTax validates the incoming payload and forwards the request to ZRA SIS for processing.

During this stage:

• Data validation checks are performed
• Tax compliance rules are enforced
• ZRA references may be generated

Step 5: Response Handling

After processing, a response is returned back through DigiTax to ERPNext.

The response may include:

• Submission status
• Reference numbers
• QR Url or compliance identifiers
• Validation messages
• Error details (if any)

The response is stored within ERPNext for audit and tracking purposes.

#Step 6: ERPNext Transaction Update

The original ERPNext transaction is updated automatically with:

• Compliance status
• Submission timestamps
• Reference information
• Validation outcomes

Users can then monitor the transaction directly from ERPNext.

Background Processing

To improve reliability and performance, many compliance operations may run asynchronously using ERPNext background jobs and queue workers.

This approach helps:

• Prevent delays during invoice submission
• Handle high transaction volumes efficiently
• Retry failed transactions automatically
• Improve system responsiveness

#Supported Transaction Types

The integration supports several compliance workflows.

• Sales Transactions: Sales invoices are transmitted to SIS for tax reporting and compliance validation.
• Inventory and Item Synchronization: Items and classifications may be synchronized to ensure consistency between ERPNext and compliance systems.
• Customer Management: Customer details are processed and transmitted appropriately.

Error Handling and Retries

If a submission fails due to validation issues, connectivity problems, or API errors, the integration records the failure and preserves the transaction state.

Depending on configuration and workflow:

• Failed submissions can be retried automatically
• Users may manually trigger resubmission
• Detailed logs are maintained for troubleshooting

This ensures that failed compliance operations do not result in data loss.
