Core Accounting Implementation Checklist

Use this guide if your first implementation goal is accounting discipline: cleaner ledgers, faster month-end review, fewer manual adjustments, and more dependable finance reports. It is useful for finance managers, accountants, founders, and implementation leads preparing an ERP rollout.

If your accounting rollout includes operating teams, read Accounting implementation checklist as well. If your main pain is month-end delay, review Why month-end close takes too long.

Start by deciding what must be controlled in phase one. Core accounting fails when teams try to reproduce every old spreadsheet, report, and shortcut without agreeing on the future process.

• Confirm the reporting outputs leadership needs every month.
• Review the chart of accounts and remove unused or duplicate accounts.
• Define cost centers, branches, departments, projects, or other reporting dimensions.
• Identify recurring journals and recurring manual adjustments.
• Confirm which periods can be edited and who can unlock them.

This preparation makes the ledger structure easier to govern after go-live.

A strong core accounting phase should include these decisions before the first live period.

1. Chart of accounts is approved by finance leadership.
2. Opening balances are validated and documented.
3. Journal entry types and approval rules are defined.
4. Receivable and payable aging reports are reviewed before go-live.
5. Bank and cash reconciliation process is tested.
6. Period close, period lock, and adjustment rules are documented.
7. Standard financial reports are agreed before launch.

The first objective is not to automate every exception. It is to give the finance team one controlled operating rhythm.

Core accounting requires strict role clarity. Decide who can post journals, approve adjustments, edit master data, close periods, reopen periods, and export financial reports. Also decide which activities require review: manual journal entries, write-offs, credit notes, supplier payments, and opening balance changes.

Use Trust to align access, approval, and governance expectations before the system becomes the reporting source of truth.

• Accounting for journals, ledgers, receivables, payables, reconciliation, and financial reports.
• Exports for controlled review packs, audit extracts, and management reporting datasets.
• CRM & Sales when customer invoices and collections are part of the first workflow.
• Procurement when supplier bills and approvals affect close accuracy.

• Importing the old chart of accounts without cleanup.
• Allowing too many people to post or edit accounting records.
• Leaving period close rules informal.
• Defining dashboards before validating the underlying reports.
• Treating exports and audit trails as optional.
