Business problem

Owners get P&L reports showing variances but no explanation — they see payroll is over budget without understanding if it was overtime, a new hire, or revenue shortfall.

Expected outcome

Monthly variance narrative: what beat or missed budget, why in plain English, which variances are one-time vs structural, and recommended owner actions.

Who it's for: SMBs with an annual budget in a spreadsheet who review actuals monthly but lack time to write the analysis themselves.

4 options listed

No-code options	Low-code options	Custom build stack
Budget vs actual Google Sheet + ChatGPT monthly narrative	n8n month-end: QBO actuals → Sheets compare → Claude narrative	Accounting API month-end pull
QuickBooks classes report + Claude long-doc analysis	Airtable budget tracker + GPT explainer field	Budget file sync from Sheets
Excel budget template + GPT variance column	Make.com accounting close workflow	Claude for long variance narrative with line-item context

Start with no-code to validate the workflow. Move to low-code when you hit rate limits or need branching logic. Custom build when volume, privacy, or integration depth requires it.
