Accounting Engine

Use When

• The product handles money, inventory value, payroll, tax, customer balances, supplier balances, assets, grants, donations, loans, refunds, wallet balances, or financial reporting.
• A SaaS must replace routine bookkeeping in external products such as QuickBooks, Xero, Sage, Pastel, Tally, Zoho Books, or Wave.
• You need architecture, schema, posting rules, tests, documentation, or review findings for ledger-backed business software.

Do Not Use When

• The task is only financial analysis or projections without software architecture; use accounting-finance-controller or the business-plan finance skills.
• The system only displays imported accounting reports and does not create business events or postings.
• A jurisdiction requires a licensed accountant, auditor, or tax practitioner to exercise professional judgement; design the system support, but do not claim the software replaces that judgement.
