BAS software
BAS software for Australian small business
Cashbooc turns your bank transactions into a Business Activity Statement you can actually check — G1, 1A, G11 and 1B in the ATO's own layout, backed by a GST detail report that reconciles line by line, and lockable periods once you've lodged.
Cashbooc prepares your BAS figures. Lodgement is done by you or your registered agent through the ATO.
How Cashbooc prepares your BAS
1. Import your bank statement
Upload a CSV from any Australian bank. Columns are detected automatically and duplicates are skipped.
2. Code with the right GST treatment
Each line gets an account and a GST code — GST on Income, GST on Expenses, GST Free, Input Taxed or BAS Excluded. AI suggests them; saved rules apply them next time.
3. Run the BAS summary
Pick the quarter, month or year and the statement summary fills in G1, 1A, G11 and 1B in the ATO's own layout.
4. Check, lodge and lock
Reconcile the GST detail report against the summary, fix any coding by drilling into the transaction, then lock the period once you've lodged.
What the BAS and GST tools do
ATO-style statement summary
The BAS page mirrors the layout of the paper statement, so the figure you read is the figure you enter — no translation between report and form.
GST detail report that reconciles
Every debit and credit behind the BAS, broken down by GST rate and basis, with a reconciliation panel that flags any mismatch against the summary totals.
Cash or accruals basis
Choose the accounting method your business reports on, along with your BAS cycle, and the calculations follow it.
Drill down and recode
Click a figure to see the transactions behind it, change a GST code, add a note or flag it for review — and watch the totals recalculate immediately.
Lock lodged periods
Lock each BAS period once lodged, and lock a whole financial year, so reported numbers can't shift underneath you.

GST codes you'll use on a BAS
| GST code | Typical use | BAS effect |
|---|---|---|
| GST on Income | Taxable sales you charge GST on | Adds to G1 and 1A |
| GST on Expenses | Purchases with GST in the price | Adds to G11 and 1B |
| GST Free | Basic food, most health and medical supplies | Counts in totals, no GST claimed or paid |
| Input Taxed | Residential rent, some financial supplies | No GST charged and no credit claimed |
| BAS Excluded | Wages, transfers between your own accounts, ATO payments | Left out of the BAS entirely |

BAS software questions
What is BAS software?
BAS software works out the figures you report on a Business Activity Statement — GST on sales, GST on purchases, and PAYG amounts — from the transactions in your books, so you can copy them straight onto the ATO form instead of adding them up by hand.
Does Cashbooc lodge my BAS with the ATO?
No. Cashbooc prepares the BAS figures and a supporting GST detail report. You lodge through myGov, the ATO Business Portal or your registered tax or BAS agent.
Which BAS labels does it calculate?
G1 total sales, 1A GST on sales, G11 non-capital purchases and 1B GST on purchases, presented in an ATO-style statement summary for your chosen quarter, month or year.
Can I use it if I'm not registered for GST?
Yes. Mark the business as not registered and GST is removed from coding, invoices and reports entirely. An AI check tells you when your income suggests you should register.
What happens after I lodge?
Lock the BAS period. Locked periods can't be edited, so the numbers you reported to the ATO stay exactly as lodged.
Do I need to be a bookkeeper to use it?
No. You import a bank CSV, the AI suggests an account and GST code for each line, and you confirm. Everything behind the BAS is a real double-entry ledger you can drill into.
