The introduction of e-invoicing is revolutionizing how businesses manage compliance, tax reporting, and record-keeping globally. In Malaysia, for example, the Inland Revenue Board of Malaysia (LHDN/IRBM) has mandated e-invoicing through the MyInvois Portal under a phased timeline starting in 2024. Other jurisdictions, including Singapore and the EU, are adopting similar frameworks based on the Peppol standard to improve transparency, reduce fraud, and streamline tax compliance.
If your business operates in Asia or anywhere that’s moving towards mandatory e-invoicing, you need a system that can handle compliance smoothly while keeping your accounting accurate. That’s where Xero comes in. With its integration to local tax authorities and its subsidiary Tickstar, Xero offers built-in e-invoicing tools that make it easier to submit validated invoices without added stress.
In this guide, we’ll walk you through practical tips on how to submit consolidated e-invoices in Xero effortlessly, avoid common mistakes, and prepare your business for evolving compliance requirements.

Why Consolidated E-Invoices Matter
If your business issues dozens or even hundreds of invoices each month, manually submitting each one to the tax authority can quickly become a time-consuming headache. That’s where consolidated e-invoices come in. Instead of sending invoices one by one, you can group all your sales invoices and self-billed invoices for a given reporting period and submit them in a single batch through Xero.
This method not only saves you valuable time but also helps keep your records clean and compliant. By letting the system pull everything together automatically, you reduce the risk of human error and ensure that your submission meets the reporting requirements set by tax authorities such as the Inland Revenue Board of Malaysia (LHDN) or other jurisdictions adopting e-invoicing frameworks.
Here’s why consolidated e-invoices are a game changer for modern businesses:
| Benefit | Why It Matters | Example |
| Efficiency | Instead of uploading or emailing every invoice separately, you submit one consolidated report covering the whole period. | A retailer with 500 sales transactions in a month can file one report instead of 500 individual invoices. |
| Accuracy | Automated consolidation reduces mistakes like duplicate entries or missing tax fields, which are common when handling invoices manually. | A service firm avoids penalties because Xero ensures all tax numbers and classification codes are included automatically. |
| Compliance | Meeting deadlines is easier when you’re working with a single file rather than chasing multiple invoices. This helps you stay aligned with mandatory e-invoicing timelines. | Businesses in Malaysia must submit by the 7th of the following month. Consolidation makes this less stressful. |
| Audit-ready | Consolidated e-invoices create a structured digital trail that’s easy for both your finance team and tax auditors to review. | If audited, you can present a clean consolidated report instead of sorting through thousands of individual invoices. |
In short, consolidated e-invoices make compliance more manageable, especially for businesses with high transaction volumes or complex reporting needs. They let you focus less on administration and more on growing your business.

10 Steps to Submitting Consolidated E-Invoices in Xero
Submitting consolidated e-invoices can feel overwhelming if you’re new to the process. But with Xero’s built-in e-invoicing features, you can streamline compliance and avoid costly mistakes. Here’s a breakdown of the 10 essential steps, explained in detail so you can follow along confidently.
1. Set Up Your MyInvois Portal (Malaysia-specific)
Before doing anything in Xero, you need to register with your local e-invoicing system. In Malaysia, this is the MyInvois Portal, which links directly to the Inland Revenue Board (LHDN/IRBM).
- Register your company as a taxpayer.
- Assign an intermediary if you want a third-party service provider to handle submissions.
- Check your portal settings carefully, especially your Tax Identification Number (TIN).
Why this matters: Any error in setup (e.g., wrong company details or missing TIN) can cause your e-invoices to be rejected when submitted through Xero.
Pro Tip: Aim to complete registration at least a month before your first mandatory submission deadline to allow time for troubleshooting.
2. Connect Xero to Your Local E-Invoice Gateway
Once your MyInvois setup is complete, connect your Xero account to the local e-invoice gateway. In Malaysia, this is Invoici, which integrates directly with LHDN’s API.
Steps:
- Log in to Xero > Settings > Business Information.
- Connect to Invoici by importing your business QR code generated by MyInvois.
- Once connected, you’ll receive a Peppol ID that confirms the integration is active.
Why this matters: Without this connection, Xero cannot transmit your invoices to the government portal for validation.

3. Enable Tracking Categories in Xero
Xero automatically creates a Tracking Category for MyInvois classification when you connect to Invoici. These categories are essential for labeling invoices correctly.
Examples of codes:
- 033 – Self-billed (Betting & Gaming)
- 034 – Self-billed (Importation of Goods)
- 035 – Self-billed (Importation of Services)
Why this matters: Tax authorities require businesses to classify invoices accurately. If invoices are not tagged correctly, they may be rejected or misreported.
Pro Tip: Check that your Xero account has at least one free slot for tracking categories before integration.
4. Update Customer and Supplier Data
Consolidated e-invoices require complete contact data. Make sure all customers and suppliers in Xero include:
- Legal entity name
- Tax Identification Number (TIN)
- Business address
- Email and phone (for verification purposes)
Why this matters: Missing or inaccurate details will cause validation errors in the government portal.
Example: If your supplier’s TIN is not updated, Xero cannot generate a valid self-billed invoice on your behalf.
5. Tag Sales Invoices with Tracking Categories
When creating sales invoices in Xero, always apply the correct tracking category. This ensures each invoice is included in the consolidated submission.
- Sales invoices must be tagged before the 3rd of the following month.
- Receipts do not need to be submitted.
Why this matters: Without proper tagging, your invoice won’t appear in the consolidated report, leaving your tax filing incomplete.

6. Handle Self-Billed Invoices with Xero’s Bills to Pay
Certain situations (e.g., imports, payments to individuals, non-business entities) require businesses to issue self-billed invoices. In Xero, this is managed through the Bills to Pay function.
Examples:
- Importing goods from an overseas supplier.
- Paying commission to an individual not registered as a business.
Why this matters: Self-billed invoices are a legal requirement under LHDN’s e-Invoice guidelines. Not issuing them could put you at risk of non-compliance.
7. Generate Consolidated Invoices Automatically
On the 4th of the following month, Xero automatically generates:
- A Consolidated e-Invoice (sales-related)
- A Consolidated Self-Billed e-Invoice (bills-related)
You’ll need to review both for accuracy before submission.
Pro Tip: If filing close to deadlines, submit early in the morning (before 8 AM) to avoid server congestion on the government portal.
8. Run a Pre-Submission Checklist
Before sending your consolidated invoices, confirm:
- Correct tax rates applied (e.g., SST 6%, 8%, or exempt 0%).
- Totals match your accounting records.
- All relevant invoices are included.
- Manual journals are excluded (they don’t appear in consolidated invoices).
Why this matters: Errors caught at this stage save time and prevent rejected submissions later.
9. Submit Before the 7th of the Following Month
The official deadline to submit consolidated e-invoices is the 7th day of the following month.. Submit directly from Xero to MyInvois or your local tax authority’s API.
- Use the dedicated Xero email addresses generated for submission (e.g., consolidated@invoi.ci).
- Check the History & Notes tab in Xero to track status.
- Once validated, a supporting PDF and a MyInvois validation URL will be available in your Xero files.
Why this matters: Late submissions can lead to compliance penalties.
10. Prepare for Future Phases
E-invoicing is being rolled out in phases based on company turnover. Even if you’re not required yet, it’s smart to get ready.
| Annual Revenue (MYR) | Effective Date | Requirement Status |
| ≥ RM100 million | 1 August 2024 | Mandatory |
| RM25 million – RM100 million | 1 January 2025 | Mandatory |
| RM5 million – RM25 million | 1 July 2025 | Mandatory |
| RM1 million – RM5 million | 1 January 2026 | Mandatory |
| Up to RM1 million | 1 July 2026 | Mandatory (with grace period) |
Preparation tips:
- Start collecting supplier and buyer data now.
- Update your SOPs for invoice processing.
- Train your finance team on tagging and classification.
- Consider engaging a consultant to smooth the transition.
Why this matters: Being proactive avoids last-minute compliance stress and sets your business up for smooth digital transformation.
Note: From 1 January 2026, any single transaction above RM10,000 must be issued as an individual e-invoice and cannot be included in a consolidated submission.

Pro Tips for Smooth E-Invoice Submission in Xero
Submitting e-invoices through Xero doesn’t have to be stressful. With the right preparation and best practices, you can avoid common pitfalls and ensure your submissions are smooth, accurate, and compliant. Here are some practical tips to help:
1. Avoid last-minute submissions
Don’t wait until the final day to send your consolidated e-invoice. Tax authorities often experience heavy system traffic near deadlines, which can cause slowdowns or even rejections. Submitting 2–3 days early gives you time to fix any errors flagged by the system and ensures your filing isn’t delayed. Think of it as a buffer that protects you from technical issues.
2. Train your team
Your finance or admin staff play a key role in ensuring invoices are submitted correctly. Make sure they understand how to:
- Tag invoices with the right tracking categories (e.g., sales, imports, self-billed).
- Enter correct Tax Identification Numbers (TINs).
- Apply proper tax rates (6%, 8%, or exemptions).
A well-trained team reduces the risk of mistakes that could lead to penalties or rejected invoices.
3. Use automation wherever possible
Xero offers tools like recurring invoices, auto-reminders, and bank feed reconciliation that can cut down manual entry. Automating repetitive tasks not only saves time but also minimizes the chances of human error. For example, if you issue monthly subscription invoices, set them up as recurring in Xero so they’re generated automatically with the correct classification.
4. Stay updated with local tax authority announcements
Rules around e-invoicing are still evolving, especially in Malaysia and other regions where phased rollouts are happening. Follow updates from IRBM/LHDN (or your local authority) to stay on top of new requirements, code changes, or extended deadlines. Subscribing to official newsletters or industry alerts can help you stay compliant without surprises.
5. Engage experts when needed
E-invoicing compliance can get complicated ,especially if you handle imports, self-billed invoices, or high transaction volumes. Partnering with a certified Xero consultant or tax advisor ensures your setup is correct from the start. They can review your workflows, catch issues before they become costly, and guide you through audits with confidence.
