Yes. n8n has a native Google Sheets node, so a common Australian build pulls transactions from Xero or MYOB on a schedule, applies your GST tax-code logic, and writes a tidy BAS-prep summary into a Sheet — GST collected, GST paid, and the net position — with each figure linked back to its source rows. It does not lodge your BAS (that stays with your accountant or the ATO portal), but it removes the manual spreadsheet assembly that eats a day each quarter and keeps every number traceable.
What the workflow does
- Pulls the period transactions from Xero or MYOB.
- Applies GST tax-code rules and the rounding reconciliation check.
- Writes a BAS-prep summary to Google Sheets with source-row links.
- Runs on a schedule ahead of each quarterly deadline.
It pairs with the invoice automation guide and the GST-rounding FAQ.
Related questions
Does the Google Sheets BAS workflow handle GST rounding?
It should — include the reconciliation check that compares stated GST to one-eleventh of the total and flags mismatches, rather than trusting a single figure. See the GST-rounding FAQ for the exact rule.
Can it run automatically each quarter?
Yes — schedule it (or trigger it on demand) so the BAS-prep Sheet is refreshed ahead of each quarterly deadline. A seasonal refresh keeps it accurate as tax codes or accounts change.
