MyInvois Portal vs SQL Accounting: Choosing Your e-Invoice Workflow
Reviewed by: Bryan Cheong, CEO, Syntax Technologies Sdn Bhd
Official sources checked: 9 September 2026
Businesses can submit e-Invoices through the MyInvois Portal, an API-connected system, or both, provided submissions are not duplicated.
Choose a workflow based on invoice volume, existing accounting processes, staff capacity and integration needs. Check your implementation obligations separately in our Malaysia e-Invoice Guide.
Which Workflow Should You Evaluate?
| Business situation | Workflow to evaluate |
|---|---|
| Small invoice volume and limited integration needs | MyInvois Portal |
| Regular invoicing already managed in SQL Accounting | SQL Accounting integration |
| Multiple teams or systems | A documented workflow with clear submission ownership |
This is a practical selection guide, not a mandatory LHDN classification.
Before deciding, compare setup costs, ongoing fees, training, data preparation and support. Software integration can reduce repeated entry, but users must still review transaction data and resolve validation issues.
Using SQL Accounting Integration
Discuss your SQL Accounting version and available modules with our team. Confirm how your staff will prepare documents, submit them to MyInvois, check returned statuses and handle corrections.
An integration does not replace responsibility for correct transaction data or the applicable tax rules. Explore SQL e-Invoice setup, training and support.
Using MyInvois Portal
Evaluate the portal’s current document-entry and upload options against your invoice volume and staff workflow. Prepare the required data before submission and track the result. Avoid submitting the same transaction again through a separate integration.
Examples of e-Invoice Data Fields
These examples are not a complete technical specification. Required fields depend on the document type and transaction.
| Field group | What to prepare |
|---|---|
| Supplier and buyer details | Names, TIN and relevant registration or identification details. |
| Document reference | Your invoice, credit note, debit note or refund note reference. |
| Document issue date and time | Enter the actual issue date and time in accordance with the current MyInvois validation rules and your submission method. |
| Products or services | Descriptions, classifications, quantities and prices, as applicable. |
| Tax information | Applicable tax type, rate, amount and exemption details where required. |
| Totals | Document totals and applicable tax calculations. |
For current technical field requirements, refer to the MyInvois SDK.
When Validation Fails
Review the returned error, correct the relevant data and resubmit as appropriate. Distinguish a rejected submission from corrections to an already validated document; use the procedure for that document’s status.
Keep a record of submission ownership and corrections so that your team can investigate problems without creating duplicate submissions.
