Troubleshooting

Purpose

Start here when opening balances do not generate, the trial balance does not balance, an e-Invoice is Invalid, or a reconciliation difference will not clear.
Each fix continues in the chapter that owns the screen.

Ask the symptom in everyday words, starting with how to if you want the steps only. See Ask how-to vs do it for me.
Profit this month and Who owes me read the books. See Ask the books. They do not repair a difference.

You are in the company that owns the figures. See Switch Company.
The document or the report date is in an open month. A locked month or a closed year blocks edits. See Month-end close and Year-end closing.

The red debtor, creditor, and stock rows fill only when you Save opening balance after the source documents exist.
Confirm Financial Start Period and System Conversion Date are saved. See Financial start period.
If the two dates are the same, Profit & Loss rows are hidden. That is expected. It is not a failed generate.
Enter unpaid customer and supplier bills dated before conversion, and confirm Save as past invoice. See Customer and supplier opening balances.
Enter stock value and save it. See Stock value.
Open General Ledger → Maintain Opening Balance.
Do not type the red control rows or a parent account.
Click Save again. This Save generates those red amounts. See Opening balance.
Open Trial Balance. Debtors, creditors, and stock should match the past bills and the stock value. See Trial balance.
The first Save, before past bills and stock, does not create the red figures.

Open Financial Report → Trial Balance. See Trial balance.
If debit and credit totals differ, double-click the odd amount (not the account name).
Find a journal with only one side, or a control account you typed by hand. Correct that document. See Journal entry and Opening balance.
If debtors, creditors, or stock are zero or wrong, finish past invoices and stock value, then Save opening balance again.
If a report says Please setup Retain Earning, add an active Retain Earning sub-account and search again. See Chart of accounts.
For a closed year, tick Financial Year and pick that year. See Year-end closing.

Open E Invoice → E Invoice Listing, or in chat say Check e-Invoice status. See Submit and check status.
Read the Invalid reason on the row.
Fix the data, then Submit E Invoice again.
Company TIN, address, MSIC, Client ID — LHDN Client ID Setup and company e-Invoice profile. See LHDN Client ID.
Buyer or supplier TIN — Edit customer e-Invoice or Edit supplier e-Invoice. See Buyer and supplier TIN.
Classification or UOM — product Classification and E-Invoice UOM, or the company default classification. See Categories and products.
Invalid Client ID or Client Secret — re-copy the ID and secret from MyInvois. See LHDN Client ID.
Click Refresh E-Invoice Status until the row is Valid or Invalid again.
Do not delete a document that is Submitted or Valid. Cancel only within 72 hours. After that, use a credit note, debit note, or refund note. See Credit, debit, and refund notes.

Use the list that matches the screen you are on. They are different checks.
Bank Reconciliation — Out Of Balance By is not zero. See Bank reconciliation.
Open Bank → Bank Reconciliation.
Set the bank and the reconciliation date (the statement date).
Compare ticked lines with the statement. Untick a wrong match. Tick a missing one.
Post any bank line that is on the statement and not in the books. See Cash book payment and receipt, Customer receipt, and Supplier payment.
Re-enter Bank Statement Closing Balance for that year and bank.
Save only when Out Of Balance By is zero. The next month stays blocked until this one is zero.
Cash Flow Statement — Reconciliation difference is not zero. See Cash flow statement.
Open Financial Report → Cash Flow Statement.
Check Maintain Stock Value for the period. See Stock value.
Check that bank and cash accounts are marked as bank or cash on the chart. See Chart of accounts.

Click Search again.
Chat Can I pay this uses book cash. It will not match the bank’s own balance until this recon is done. See Ask the books and Bank reconciliation.

Save on opening balance does nothing. The role needs openingBalance_new or openingBalance_edit. See Permissions.
Year End Closed, Cannot Delete/Edit/Add transaction. The date is in a closed year or a locked month. See Year-end closing and Month-end close.
Invalid comes back with the same reason. The master was fixed after submit. Submit again so MyInvois receives the new TIN or address.
Cheque did not auto-match. The cheque field must be digits only. Edit it and retrieve again. See Bank reconciliation.
