Introduction
Bringing an external bookkeeper on board should reduce owner workload while increasing confidence in tax compliance, cash visibility, and profitability reporting. The bookkeeper’s role is to deliver reliable outputs and clear signals so the owner can review and redirect, not get pulled into day‑to‑day transactions. Design the relationship around guarantees, simple SLAs, and automatic escalation rules.
Three strategies to implement bringing an external bookkeeper on board
Strategy 1 Guarantee the essentials first
Bookkeeper guarantees of tax compliance and BAS readiness, clear cash visibility, and accurate profitability reporting as the minimum scope.
Write these as non‑negotiable acceptance criteria into the service agreement.
Strategy 2 Minimise owner time — eliminate, automate, delegate
Design processes so the owner’s role is decision‑focused.
Eliminate manual handoffs; automate bank feeds, invoice rules, and AR reminders.
Delegate reconciliations and month‑end cleanup to the bookkeeper; owner receives a concise snapshot and only acts on exceptions.
Strategy 3 Define cadence, deliverables, and escalation triggers
Agree clear deliverables (weekly cash snapshot, monthly reconciled P&L, BAS‑ready pack) and cadence tied to the business’s tax cycle or cash needs.
Set escalation triggers such as runway < 8 weeks or current ratio < 1.2.
Require a 48‑hour recovery note with ownerable actions when triggers are hit.
Implementation checklist
Access & credentials — secure read/write access to cloud accounting, bank feeds, payroll, billing.
Initial handover — last 12 months reconciled accounts, COA, open AR/AP, retainer balances.
COA & tax mapping — map accounts to lodgement lines and confirm BAS settings.
Bank feeds & rules — connect feeds and create rules for recurring items.
Reporting templates — implement weekly cash snapshot and monthly reconciled P&L.
SOPs & scripts — short scripts for AR follow‑up, retainer application, and month‑end close.
Pilot month — reconcile one live month, surface exceptions, refine rules, confirm SLAs.
Practical onboarding checklists and templates are widely available and can speed setup and reduce errors.
Next steps
Share this checklist with shortlisted bookkeepers and confirm SLAs.
Run a 30‑day pilot with weekly snapshots and one reconciled month.
Lock the cadence, automation rules, and escalation playbook after the pilot.
