Question 1

Why combine BAS and bookkeeping into one workflow instead of treating them separately?

Accepted Answer

Because the two are the same data viewed at two points in time. A BAS is only as accurate as the bookkeeping it is reconciled from — if the GST coding, contractor splits and clearing accounts are wrong during the quarter, the BAS becomes a clean-up exercise at the deadline. Running both as one workflow means coding decisions are made once, at the transaction level, and the quarterly BAS becomes a confirmation of an already-clean file rather than a reconstruction. The downstream benefit is that the annual company or trust return then starts from numbers that have already been reconciled twelve times.

Question 2

How is this page different from the Hills District BAS & bookkeeping location page?

Accepted Answer

The location page sets out the regional office detail — who we serve across Norwest, Bella Vista, Castle Hill and Baulkham Hills, the Cherrybrook office and the tier pricing. This page is the service-workflow view: it explains how clean books feed an accurate BAS, how the monthly close works, and how those reconciled figures roll into the annual return. If you are searching by location, start with the location page; if you want to understand the mechanics of the combined engagement, you are in the right place.

Question 3

What does a typical Hills District file look like on this engagement?

Accepted Answer

Most of the businesses we run this way are already on Xero with a live bank feed and payroll inside Xero. The mix across the corridor is broad — Castle Hill retail and services, Norwest and Bella Vista Pty Ltd professional services, IT consultancies and allied health practices, and trades operating up and down the M7/Windsor Road spine. The common thread is recurring GST, regular payroll under STP, and a year-end company or trust return at the back. We tune the coding discipline to that profile rather than running a generic chart of accounts.

Question 4

How do GST coding and PAYG flow from the books into the BAS?

Accepted Answer

During the month, every transaction is coded to the chart of accounts with the correct GST treatment — GST on expenses, GST-free, BAS-excluded or capital — at the point it is reconciled, not retrospectively. Payroll runs on its cycle and STP is filed each pay run, which builds the W1 and W2 figures. At quarter close, the GST control accounts and the PAYG withholding total are reconciled against the trial balance, the PAYG instalment is confirmed against the ATO notice, and the BAS labels are mapped directly from those reconciled balances before lodgement.

Question 5

Can you take over a file that is already running with another bookkeeper or agent?

Accepted Answer

Yes. Transferring the BAS lodgement obligation between registered agents is a defined ATO process handled through Online Services for Agents, and we pick it up from the next quarter. The bookkeeping handover is the larger piece of work: we review how the existing file is coded, document any treatments that conflict with how we run a file, and unwind them cleanly so the combined workflow is consistent going forward. That review is scoped and quoted before we start.

Question 6

Where does payroll and STP finalisation sit in the workflow?

Accepted Answer

Payroll is part of the same engagement, not a bolt-on. Pay runs are processed on the scheduled cycle, super is reconciled monthly, and STP is filed each run so the year-to-date figures stay accurate. At year-end, STP finalisation reconciles gross wages, PAYG withheld, super and any reportable amounts against the trial balance before the finalisation declaration is lodged, so employees receive correct income statements on myGov. There is a dedicated Payroll & STP page if you want the detail on that part alone.

Question 7

What sits outside this combined BAS and bookkeeping workflow?

Accepted Answer

The workflow ends at a reconciled file and lodged activity statements. The annual financial statements, the company or trust tax return, and the year-end planning conversation are separate scoping items — usually quoted alongside the BAS and bookkeeping so the full annual rhythm is visible from the start. Anything strategic, such as a restructure, a virtual-CFO cadence or a lending application, is also scoped separately. The point of the combined workflow is that all of those later pieces start from books that are already clean.
