Financial report explanations

Understand the month.
Not just the numbers.

Founder-delivered monthly P&L explanations for small service businesses. Understand what changed, what the figures support, and what deserves a closer look.

The problem

Revenue is up.
So why is profit down?

A P&L can show the totals without explaining the movement. For an owner running a small service business, comparing months, tracing cost changes, and separating facts from possible causes takes time.

The planned service is deliberately narrow: explain a monthly P&L comparison in plain English, with the relevant source lines alongside the explanation. It would not replace bookkeeping, accounting review, tax advice, or business judgment.

Intended workflow · Not implemented

Calculate first. Explain second.

  1. 01

    Start with the source

    The planned workflow would use two comparable monthly P&L statements, retaining the period, currency and source line for each figure. Missing or inconsistent inputs would be flagged.

  2. 02

    Validate the numbers

    Deterministic code would calculate totals, differences and margins, and check that revenue minus expenses reconciles to profit. Claude would not be the authority for arithmetic.

  3. 03

    Explain the movement

    Claude would interpret the validated comparison. Each factual claim would point back to a source line; possible causes and follow-up questions would be distinguished from facts.

A look at the planned format

An explanation you can trace.

The sample below is manually written using invented figures. It demonstrates the intended format only; it is not an AI-generated report or a result from a client.

Illustrative report

Revenue grew. Profit did not.

Profit · Month B

Synthetic profit and loss comparison in US dollars. All figures are invented for this example.
P&L lineMonth AMonth BChange
Revenue$20,000$22,000+$2,000
Subcontractors$6,000$9,000+$3,000
Other expenses$8,000$8,000$0
Total expenses$14,000$17,000+$3,000
Profit$6,000$5,000−$1,000
Profit margin30.0%22.7%−7.3 pp

What changed in this example

Revenue rose by $2,000, but expenses rose by $3,000. The synthetic subcontractor line accounts for that expense increase. Profit therefore fell by $1,000, from $6,000 to $5,000.

Example source: table above, Revenue / Subcontractors / Total expenses.

A question, not a conclusion

Was the subcontractor increase one-off, tied to extra work, or a change in rates? These figures alone cannot establish why it happened. Review the underlying invoices and project records before drawing a conclusion.

Profit = revenue − expenses. Margin = profit ÷ revenue. Percentages rounded to one decimal place.

All figures and categories are synthetic. This is a manually authored illustration of the planned format, not a client report, evidence of outcomes, or a currently available AI feature.

Planned safeguards.
Honest limitations.

These are design intentions, not implemented protections or audited controls. An explanation is only useful if you can check its basis.

Read our methodology
  • Reconciled arithmetic

    Check totals and period comparisons in code. Flag discrepancies instead of inventing a balancing number.

  • Source-grounded statements

    Tie factual narrative to the supplied P&L lines. Avoid filling gaps with assumed business context.

  • Uncertainty made visible

    Separate an observed change from a possible explanation. A P&L alone cannot prove the reason a cost rose.

  • Review before relying

    Keep original figures visible for user review. AI can make mistakes; the planned output would not be financial or tax advice.

  • Data handling to be defined

    Before any launch, document the actual processing, providers, retention and user choices. Current browser-local calculator behavior is not a promise about a future AI service.
