How monthly bookkeeping usually works
A solid monthly bookkeeping process starts with onboarding: understanding your structure (sole trader, company, partnership or trust), software setup, reporting cadence, and any urgent items (overdue BAS, payroll issues or backlog). From there, each month follows a predictable checklist:
- Collect source data: bank feeds, expense apps, invoices and payroll inputs.
- Code transactions and reconcile bank, card and payment gateway accounts.
- Review accounts payable (bills) and receivable (invoices) for accuracy and follow‑up.
- Check payroll, STP reporting and Super Guarantee obligations.
- Apply GST rules, prepare BAS workpapers and, if engaged, lodge via a registered BAS agent.
- Post month‑end journals (depreciation, accruals, prepayments, stock where applicable).
- Produce management reports with commentary and a short monthly update or meeting.
Australian context to keep in view
- Monthly bookkeeping supports GST and BAS accuracy, payroll compliance (STP Phase 2) and Super Guarantee timing.
- It reduces end‑of‑year tax cleanup and helps you make decisions with current cash flow and profit numbers.
- If you file BAS quarterly, monthly bookkeeping still prevents quarter‑end pile‑ups. If you file BAS monthly, it’s essential.
- Industries with TPAR reporting (e.g., building and construction, cleaning, courier, IT, security) benefit from consistent supplier coding during the year.
Combine monthly bookkeeping with payroll services for headcount growth, and use a small business accountant or tax accountant for year‑end and tax planning.
What to compare before you commit
Scope
Confirm inclusions: reconciliations, A/P and A/R, payroll reviews, BAS prep and lodgement, month‑end journals, reporting and meetings. Ensure cleanup/catch‑up is quoted if needed.
Software fit
Ask for fluency in your tools (Xero, MYOB, QuickBooks Online and add‑ons). The provider should explain the workflow, not just name the software.
Turnaround and communication
Agree on cut‑off dates, reporting deadlines and how urgent questions are handled. Look for proactive communication, not just silent processing.
Compliance credentials
If you want BAS lodged, confirm the provider is a registered BAS agent. Check experience with STP and super.
Commercial fit
Match pricing method (fixed vs hourly), meeting rhythm, and reporting depth to your needs—compliance‑only or advisory‑leaning.
What’s included in monthly bookkeeping
- Monthly reconciliations across bank accounts, credit cards and payment gateways.
- Supplier bills and customer invoice processing with A/P and A/R review.
- Payroll checks, STP review and Super Guarantee tracking (with optional payroll services).
- GST review and BAS preparation, plus lodgement if engaged with a BAS agent.
- Month‑end journals: depreciation, accruals, prepayments and inventory adjustments where relevant.
- Management reports and commentary tailored to your business.
If your file needs work before monthly processing can start, use bookkeeping clean up or catch up bookkeeping to get current, then move to a monthly rhythm.
Monthly bookkeeping pricing in Australia
Pricing depends on transaction volume, payroll headcount, number of bank feeds, inventory/add‑ons and whether you need BAS lodgement and advisory time.
- Micro businesses: typically $250–$600 per month.
- Small businesses: typically $600–$1,500 per month.
- Complex or multi‑entity: $1,500+ per month.
Packages should include clear scope, deliverables, turnaround times and any variable items (e.g., extra payroll cycles, new integrations).
Monthly vs quarterly vs weekly
- Monthly: best balance for most businesses—supports BAS, payroll oversight and timely decisions.
- Weekly: choose for higher volumes, ecommerce, inventory or tighter cash collection.
- Quarterly: suits very low‑volume micro businesses but increases risk of quarter‑end surprises.

Best next steps
Write down the outcome you need: cleaner books, BAS lodged, payroll confidence, meaningful monthly reports, software migration or advisory. Shortlist providers against that outcome—not just titles. The right fit explains the process, sets timelines and links the work to decision‑making.

Prepare a handover list: software access, bank feeds, payroll YTD balances, open A/P and A/R, and outstanding BAS. Run a short parallel period to verify coding and reports, then move onto the monthly cycle.
