# Finance Pl

> Build a profit and loss statement from revenue and expense inputs, with period-over-period comparison, margin analysis, basis-of-accounting handling (cash / accrual / modified cash) and ASC 606 deferred-revenue treatment for subscription revenue. Use when the question is whether a period made money and where the margin went. Do NOT use for what the business owns and owes at a point in time (use finance-balance-sheet), for whether cash actually moved (use finance-cashflow), or for forward-looking burn and time-to-zero (use coin-runway-and-burn). Statements and analysis only — have a CPA review anything filed or handed to a lender.

> **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.

## 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

## Material variance flags (scale-aware)

Apply the threshold appropriate to business scale (single-flat threshold misleads at scale):

| Revenue tier | Variance flag threshold |
|---|---|
| <$1M annual | 10% **or** $500 (whichever is smaller) |
| $1–10M annual | 5% **or** $5,000 |
| $10M+ annual | 3% **or** $25,000 |

Flag any line item exceeding the applicable threshold for investigation:

| Line Item | Variance ($) | Variance (%) | Direction | Likely driver |
|---|---|---|---|---|
| [Item] | $X,XXX | X.X% | Unfavorable | Investigate |

## Margin benchmarks (SMB reference - split bootstrapped vs venture-funded)

| Business type | Bootstrapped SMB gross | VC-backed gross | Bootstrapped net | VC-backed net |
|---|---|---|---|---|
| Software / SaaS | 75–90% | 65–85% | 5–15% | -50% to +25% (often negative - investing in growth) |
| Professional services | 40–60% | 40–60% | 10–25% | 10–20% |
| E-commerce / retail | 30–50% | 30–50% | 2–8% | -30% to +5% |
| Manufacturing | 25–45% | n/a | 5–15% | n/a |
| Restaurants / food service | 55–70% (food cost 30–45%) | n/a | 2–9% | n/a |
| Agency / services-firm | 40–60% | n/a | 10–20% | n/a (utilization-rate proxy: 65–75% billable) |

**Owner-comp normalization note:** for sole-prop and S-corp comparisons, normalize net margin by adding back / pulling out owner draws (sole-prop) or reasonable salary (S-corp) so the comparison to benchmarks is apples-to-apples. Owner compensation should be flagged distinct from wages.

## Workflow

1. Collect inputs (ask for current period revenue and expenses; prior period for comparison).
2. Build the P&L table.
3. Calculate margins and key metrics.
4. Flag material variances.
5. Output the statement with observations.
6. Offer to save to `pl-<period>.md` in the workspace.
