Bottom Line Up Front (BLUF) - Small businesses avoid penalties and cashflow shocks by fixing the usual bookkeeping slip‑ups: missed reconciliations, BAS/BAS lodgement errors, and misclassified transactions. Delegate the work, automate data flows, and escalate only material exceptions so the owner remains an exception reviewer and strategist.

Introduction
Common bookkeeping errors create risk: missed BAS deadlines, unreconciled accounts, and poor documentation can lead to penalties, audits, and cashflow problems. The owner’s role is to set the aim, approve thresholds, and sign off on material exceptions; the bookkeeper or finance lead owns the day‑to‑day controls. Automate, delegate, and escalate are the operating rules.
Three strategies to implement preventing compliance errors
Strategy 1 Enforce regular reconciliations and bank discipline
What to do: Reconcile bank, credit card, and loan accounts at least monthly; prefer daily or weekly for high‑volume accounts. Unreconciled accounts are the root cause of many downstream errors. Automate bank feeds and set a reconciliation SLA (e.g., 48 hours for exceptions).
Owner rule: Review only accounts with repeated unreconciled items or material variances.
Strategy 2 Standardise coding and classification
What to do: Lock chart of accounts categories for common expenses; use coding rules and bank rules to auto‑classify transactions. Train staff on one‑line descriptions and require receipts attached to every expense. Misclassification of expenses and missed GST entries are frequent causes of compliance issues.
Action: Run a monthly coding exceptions report; escalate only when patterns repeat or material thresholds are breached.
Strategy 3 Automate BAS and payroll controls
What to do: Automate GST tagging, BAS packs, and payroll feeds to superannuation and STP systems. Maintain a minimum viable audit trail: digital invoices, bank statements, and payroll summaries. Missing BAS lodgements and payroll errors are common and avoidable with automation.
Escalation: Flag late lodgements, unpaid liabilities, or payroll mismatches immediately; owner intervenes only for systemic or material breaches.
Implementation checklist
Ownership: Bookkeeper owns reconciliations, coding, BAS pack, and payroll feeds.
Intent: Zero surprises at lodgement; owner sees only material exceptions.
Automation: Bank feeds, coding rules, BAS templates, STP payroll, and document capture.
Documentation: Minimum viable digital records; video SOPs for key tasks.
Exception thresholds: Define dollar/percentage triggers for owner review (e.g., single variance >10% or >$X).
Cadence: Weekly reconciliations for cash accounts; monthly BAS pack and quarterly reviews.
Next steps

Mission Command Principles for Business
Build mutual trust: Leaders trust teams to act; teams trust leadership to support.
Create shared understanding: Everyone knows the vision, objectives, and constraints.
Provide clear commander’s intent: Goals and outcomes are explicit; execution is flexible.
Exercise disciplined initiative: Teams solve problems without waiting, aligned to strategy.
Use mission orders: Objectives are assigned; methods are left open.
Accept prudent risk: Smart risks are encouraged for innovation and growth.
These principles ensure the owner sets the aim, the team executes, and the system flags exceptions — without dragging the owner into the weeds.
