The e-invoicing is an initiative to boost Malaysia’s digital economy expansion and improve the effectiveness of the country’s tax administration. Traditional paper-based invoices will be replaced by electronic ones, which will improve the effectiveness of recording financial transactions and enable real-time data collecting. Businesses can develop an automated, linked, and future-ready invoicing system with Weaver’s E-Invoicing Solution, going beyond simple compliance.

Malaysia E-Invoicing Background

E-invoicing refers to the digital creation, submission, validation, and storage of invoices in a structured electronic format. It replaces paper and PDF invoices. In Malaysia, e-invoicing is being introduced in phases. Businesses will be required to comply based on the government’s rollout schedule.

All valid e-invoices must be submitted through MyInvois, which is the national platform managed by LHDN. Once an invoice is validated, the system generates a unique identifier (UUID) and submission ID. These confirm that the invoice meets legal and tax requirements. This change requires the companies to review their current practise in issuing invoices as well as how invoice data is managed, tracked, and audited across the organisation.

Challenges & Trends in E-Invoicing Adoption

As companies prepare for adopting the e-invoicing requirements, several common challenges and trends can be seen:

• System readiness and integration gap
  Most of the existing ERP, accounting, and billing systems were not designed to handle structured e-invoices or real-time validation. Due to this, the company will rely on manual work and repeated data entry daily.
• Data accuracy and standardization pressure
  E-invoicing requires strict data standards. Missing fields, inconsistent master data, and fragmented processes often cause invoice submission failures.
• Operational change and compliance management
  Finance teams need to follow new workflows, approval steps, and compliance timelines. This means staff training and process changes are required.
• Rejection handling and monitoring complexity
  Without a central view, it is difficult to track rejected invoices, correction cycles, and resubmissions. This increases operational risk.
• Trend toward automation and audit readiness
  Besides than compliance to the e-invoicing requirements, many organisations aim to achieve automated workflows, real-time visibility, and audit-ready digital records as part of digital transformation efforts.

Weaver E-Invoicing Solution Framework

Overall Weaver e-invoicing solutions

The Weaver E-Invoicing Solution is designed with a layered, end-to-end architecture that combines compliance, business processes, automation, and enterprise systems into a single unified platform. This approach guarantees that e-invoicing is not viewed as a separate compliance chore, but rather as an essential component of daily organisation operations.

Presentation Layer

Users can access the e-invoicing system via a variety of portals, including company, personal, department, business intelligence, and project portals. This allows many roles—finance, operations, management, and auditors—to engage with e-invoice data using a consistent and user-friendly interface that is accessible via online and mobile.

Tailormade E-Invoicing Features

The framework is developed around purpose-made e-invoicing tools that satisfy Malaysia’s regulatory requirements and real-world corporate workflows. These include customer master data management, sales order recording and approval, sales invoice submission and management, purchase invoice synchronization and management as well as real-time notifications. Together, these functionalities enable complete visibility and control over the whole e-invoice lifecycle, from data preparation to validation and auditing.

Low-Code Operation Automation Platform

Under the business features, Weaver’s low-code automation platform supports workflow execution, system integration, reporting, and intelligent processing. Workflow, integration, reporting, mobile, and AI engines allow enterprises to build approval flows, validation rules, integrations, and future improvements with flexibility without requiring significant redevelopment. This ensures that the solution is adaptable as regulatory policies and commercial requirements change.

Enterprise Integration Layer

The framework is meant to operate seamlessly with existing enterprise systems such as ERP, CRM, budget and expenditure systems, HR platforms, MES, directory services, and third-party apps. This allows invoice data to be pulled directly from actual business transactions, saving duplication, human entry, and reconciling effort.

Infrastructure Layer

The solution’s foundation includes enterprise-grade security, network, database, and storage components that enable flexible deployment across cloud or on-premise systems. This guarantees that scalability, performance, and data protection adhere to corporate IT and regulatory standards.

Weaver E-Invoicing Integration Architecture with MyInvois

The Weaver E-Invoicing Solution is directly integrated with MyInvois, allowing for seamless two-way e-invoice processing for both sales and purchases. The architecture is intended to assure regulatory compliance, accounting correctness, and end-to-end visibility across the invoice life cycle.

Sales E-Invoicing Flow (Outbound Invoices)

The process begins when a business creates a sales invoice in the Weaver system.

1. Invoice creation and validation
   Sales invoices are created in Weaver system depending on approved transactions. Internal validation and control checks are performed prior to submission, including approval authorization when necessary.
2. Posting to MyInvois
   Once completed, the invoice is sent straight from Weaver system to the MyInvois platform for regulatory validation. MyInvois checks the invoice content per LHDN regulations and certifies its legality.
3. Ledger posting and traceability
   Following successful validation in Myinvois platform, the invoice status, UUID, and submission ID are synchronized back to Weaver system and recorded, ensuring that financial records are consistent with regulatory data.
4. Invoice delivery to customer
   The authenticated e-invoice is subsequently given to the customer via the MyInvois platform, ensuring that they receive a legally recognized e-invoice without any further manual processes.

Purchase E-Invoicing Flow (Inbound Invoices)

For purchase invoices, the integration operates in the reverse direction.

1. Supplier submission to MyInvois
   Suppliers submit their e-invoices to MyInvois platform.
2. Automatic synchronization into Weaver
   Weaver system will synchronise the validated purchase invoices from MyInvois platform on a regular basis and consolidates them in the Purchase Invoice Management module.
3. Review and rejection
   Finance teams can analyse incoming e-invoices, reject them within the statutory time frame if necessary. If rejection is made, this status will be posted to Myinvois platform, and the supplier will receive the notification.
4. Handling PDF invoices and self-billing
   If a supplier submits a PDF invoice instead of an e-invoice, Weaver platform support to create a self-billing e-invoice to maintain regulatory compliance.
