When LHDN rejects an e-invoice, BCL keeps it under **Payments** → **MyInvois** with the reason. Pressing **Submit E-Invoice** again without fixing that reason fails again, and sending the same e-invoice twice within 10 minutes is refused as a duplicate.

## Why you see a duplicate error

LHDN blocks an e-invoice that is identical to one sent in the last 10 minutes. BCL checks this before sending: if nothing has changed since the last attempt, it shows **Nothing has changed since the last attempt** and tells you how many minutes to wait, instead of sending a submission that would fail.

So a duplicate message usually means the first attempt already failed for another reason, and the later presses were the same e-invoice again. Pressing more often does not help: find and fix the first reason.

## Find why an e-invoice failed

Failed e-invoices are on the MyInvois page:

1. Go to **Payments** → **MyInvois** and open the **Failed** tab.

   *(Screenshot: The MyInvois page with the Failed tab and the Submission Status column highlighted)*

2. Point at the status in the **Submission Status** column to see the reason, or open the row's menu and choose **View E-Invoice** for the full failure details.
3. Fix the cause. Common ones:

   | Reason | Fix |
   | --- | --- |
   | Bayarcash is not set as intermediary for your TIN | Add Bayarcash in the MyInvois Portal: see [Add Bayarcash as your MyInvois intermediary](/myinvois-intermediary/) |
   | Your TIN or company details are wrong or missing | Correct them in **Team** → **Company Profile** (the **E-Invoice Settings** button on the MyInvois page opens it) |
   | Your customer's details are incomplete or wrong | Use **Update Customer Data** in the row's menu, or **Request Customer Data** to ask the customer |

4. Click **Submit E-Invoice** once and check the status again after a few minutes.

If you corrected the details, you can submit straight away. The 10-minute wait only applies to an e-invoice that has not changed.

## Tips

A few habits avoid duplicate errors:

- **Press Submit E-Invoice once.** Submission and LHDN validation take a moment; watch the status change from **Validating** instead of pressing again.
- **Check Company Profile before your first e-invoice.** The **E-Invoice Compliance** box lists anything missing, and **Check Connection** confirms Bayarcash is your intermediary.

## Common issues

### I pressed Submit E-Invoice many times and now it says duplicate. Is something broken?

No. LHDN refuses the same e-invoice sent again within 10 minutes, so the duplicate message is a result, not the cause. Wait 10 minutes, open the e-invoice under Payments → MyInvois, read why the first attempt failed, fix that, then submit once.

### BCL says Nothing has changed since the last attempt. What do I do?

You tried to send the same e-invoice again within 10 minutes. Either wait for the time shown, or correct the details that made it fail and submit straight away.

### My customer says the e-invoice request page asks them to wait some minutes.

They sent the same request a moment ago. The page says how many minutes to wait before trying again.
