How Tax Invoice Data Works
It's important to understand how QashierHQ processes data for your tax invoices:
Key Rule: When you select a month to generate a tax invoice, the system will process data from the previous month.
Example: If you select June 2025 to generate an invoice, the system will pull data for May 2025, and your invoice will be titled "Tax invoice for May 2025."
Verifying Your Tax Invoice Data
Step 1: Download Your Payout Report For example, to verify a May 2025 tax invoice, download your payout report with extended dates. You should set the report dates from April 24 to June 7.
Why these dates? The system checks a week before and a week after the selected month to make sure it captures any transactions with delayed payouts. (May 1 minus 1 week = April 24; May 31 plus 1 week = June 7).
Filter your report by "Transaction month = May 2025" (or the relevant month you are checking).
Result: The numbers in your filtered payout report should match the totals on your tax invoice.
Step 2: Check the Numbers. Compare the key figures from your payout report with your tax invoice:
Example
Transaction Amount: Should match exactly. ($69,278.98 ✓)
Payment Fees: Expect minor differences (a few cents) due to rounding per transaction. This is normal. ($1,462.86 ✓)
GST: If applicable, this should match. ($0.00 ✓)
Common Issues & Quick Troubleshooting Steps for Tax Invoices
Here are some common reasons why your tax invoice data might not match your expectations, along with solutions and quick troubleshooting steps.
Issue | Cause/Reason | Solution/Check |
Transaction amounts don't match | A transaction occurred in the invoice month but its payout was processed in a different month. | Check if the transaction appears in the previous or next month's tax invoice. |
Payment fees have small differences (few cents) | This is typically due to rounding differences applied per individual transaction. | This is a normal occurrence and will be further improved with future system updates (Account Balance 1.0). |
Missing transactions |
| Verify the following: • The transaction must be in an approved status. • The transaction must have its payout verified within the extended payout window (e.g., April 24 to June 7 for a May invoice). • The transaction date must be within the month for which the invoice is generated (e.g., within May for a May invoice). |
GST calculation shows $0.00 | GST is calculated per individual transaction and then rounded. The total GST for the month may appear as $0.00 due to these individual rounding differences, even if small fees were subject to GST. | This is expected due to rounding at the individual transaction level. |
Quick Troubleshooting Steps (General)
To quickly investigate discrepancies, follow these steps:
Download your payout report with extended dates (e.g., previous month - 6 days to next month + 7 days).
Filter the report by the specific transaction month you are investigating.
Compare the totals from your payout report with your tax invoice.
Check for rounding differences – remember, small differences are expected for payment fees.
Verify transaction status – ensure all relevant transactions are approved with confirmed payouts.
