Generate a Profit and Loss (P&L) statement from revenue and expense inputs, with period-over-period comparison and margin analysis. Basis-of-accounting-aware (cash / accrual / modified cash); ASC 606 deferred-revenue guidance for SaaS. Ported from Anthropic's financial-statements skill.

> **Templates and analytical tools only - not personalized financial, tax, accounting, or legal advice.** P&L line classification, revenue recognition (ASC 606 / IFRS 15), and basis-of-accounting choice materially affect the figures. Review with a CPA before sharing externally (lender, investor, tax preparer).

# Finance - P&L Statement

Generate a Profit and Loss statement with period-over-period comparison and key margin metrics.

## When to use

- Monthly or quarterly P&L review
- Comparing actuals to a prior period or budget
- Building a financial summary for a business partner, lender, or investor
- Checking gross margin, operating margin, and net margin trends

> For advanced financial modeling (scenario analysis, DCF), load the financial-modeler skill via `skill_view('financial-modeler')`.

## Required first prompt - basis of accounting

Before generating the P&L, ask:

> **Basis of accounting**: `cash` / `accrual` / `modified cash` - REQUIRED.
> This materially changes what counts as "revenue" and "expense" for the period and which schedule (cash vs accrual) ties to the cash-flow statement. **Do not generate a P&L without this declaration.**

The P&L header MUST display `basis_of_accounting: <selected>` so any downstream reader sees it.

### ASC 606 / IFRS 15 deferred-revenue treatment (accrual filers)

For SaaS / subscription / annual-prepay / multi-element / progress-billed contracts, recognize revenue **as performance obligations are satisfied**, not when invoiced or cash is collected. Common SMB pitfalls:

- **Annual prepay SaaS** - invoice $12,000 in January; recognize $1,000 / month; remainder sits in **deferred revenue** liability. **A SaaS SMB selling annual prepay overstates revenue 12× without this treatment.**
- **Implementation / setup fees** - generally recognize ratably over the expected customer life unless distinct from the subscription.
- **Variable consideration** (rebates, refunds, usage credits) - estimate and constrain per ASC 606-10-32-11.
- **Right of return** - if material, recognize net of estimated returns.

Cash-basis filers do not apply ASC 606 - revenue equals cash collected in the period - but should still note the deferred-revenue economic reality when sharing the P&L externally.

## Inputs

- **Basis of accounting**: cash / accrual / modified cash (REQUIRED - see above)
- **Period**: month (YYYY-MM), quarter (YYYY-Qn), or year (YYYY)
- **Revenue** by category (product, service, subscription / recurring, other) - current and prior period
- **Cost of revenue / COGS** - current and prior period
- **Operating expenses** by category (R&D, S&M, G&A) - current and prior period
- **Depreciation & amortization (D&A)** - current and prior period (REQUIRED operating line)
- **Owner compensation / draws** (sole-prop or S-corp) - flagged separately for normalization
- **Other income / expense** (interest, one-time items) - optional
- **Tax rate** - optional; if unknown, output pre-tax income and note
- **Budget** - optional; include for budget vs actual variance column
- **Business scale**: revenue tier (`<$1M` / `$1–10M` / `$10M+`) - used to set scale-aware variance thresholds
