This “FreeAgent alternative” listing points to ERPNext Accounting. Trial it with a small business scenario: customer invoice, supplier bill, payment, tax entry, and bank reconciliation. Compare the resulting ledger and reports with an independent set of expected totals.
ERP scope can be valuable but brings configuration and training. Confirm local accounting requirements with a qualified professional, test permissions and an export, and rehearse a backup restore. Adopt it only when the workflow and financial statements remain understandable and correct.
