Preparing a Chart of Accounts before ERP Setup

A practical checklist for building a reviewable chart of accounts, from required reports to numbering, testing and approval before ERP import.

Use this guide before moving accounts into new accounting software. The aim is not to multiply accounts, but to create a structure understood by the person posting a transaction and the person reviewing the report, with documented decisions for unusual accounts.

Prepare the inputs

  • Latest approved trial balance and current chart of accounts.
  • Statements and reports used by management and the accountant.
  • Branches or analysis areas that need separate reporting.
  • Representative sales, purchase, expense, asset and adjustment examples.
  • A preparer, reviewer and approval date.

Work through the checklist

  • Classify accounts into assets, liabilities, equity, income and expenses.
  • Separate active and old accounts without deleting historical records.
  • Choose numbering that allows later additions.
  • Decide what belongs in a subledger rather than one ledger account per party.
  • Test representative entries and resulting statements.
  • Retain a numbered, dated and approved final version.

Compare account counts by group, confirm where every opening balance will go and make sure control accounts reconcile to detail. Use the chart-of-accounts article and opening-balances guide, then ask to drill from statements to account and transaction during the Wali ERP demonstration.

Do not change classification merely because an import template accepts a row. Set policy first and document every mapping between old and new charts so reconciliation can be repeated.
