How to explain a P&L to a client in plain English (with an AI prompt)

The problem: clients see numbers, not a story

A P&L answers a simple question — what came in, what went out, and what was left — but the format hides that simplicity. Account names are technical, subtotals are stacked, and the client doesn't know which lines matter.

Writing a clear explanation for every client every month takes time, so it often gets skipped. That's exactly the kind of repeatable writing task AI can draft for you, as long as you set the rules.

A plain-English structure that works

I walk clients through four questions, in this order:

• What came in? Total income for the period.
• What did it cost to deliver? Cost of goods sold, and the gross profit left after it.
• What did it cost to run the business? Total operating expenses, with a few of the larger lines named.
• What was left? Net income — and anything on the report that still needs a question answered.

Walking through a fictional example

Here's a fictional P&L for a made-up company. Using the four questions, the explanation might read: "In September, Riverbend Landscaping brought in $48,200 in income. Materials and subcontractors for those jobs cost $12,900, leaving $35,300 in gross profit. Running the business — rent, fuel, insurance and wages — cost $27,450. That left $7,850 in net income. There's also $640 recorded as Uncategorized Expense that we'll want to confirm."

Notice what's missing: no judgment, no advice, no prediction. Just what the report shows, in sentences.

The AI solution: a prompt that drafts the explanation

Copy this prompt, paste in the P&L totals (fictional or properly anonymized), and let the AI write the first draft.

You are helping a bookkeeper explain a Profit and Loss report to a small-business owner who is not an accountant.

Rules: Use only the numbers provided. Do not round, change or invent numbers. Do not give tax, legal, financial or business advice. Use neutral language — do not call any result good, bad, strong or weak.

Structure: Answer four questions in short paragraphs: What came in? What did it cost to deliver? What did it cost to run the business? What was left?

Then add a list titled "Items to review" for any Uncategorized or Miscellaneous amounts, negative numbers, or totals that don't tie.

End with: "Informational summary only. No changes made. Not advice."

What you check before sending

Read the draft with the report next to it. I check:

• Every dollar amount matches the report exactly.
• Gross profit equals income minus cost of goods sold, and net income ties to the report.
• No sentence gives advice or predicts the future.
• Words like "healthy" or "concerning" have been removed.
• Review items are listed as questions, not conclusions.
• The tone sounds like you, not like a robot or a salesperson.

Make it a monthly habit

Once your prompt works, save it. Each month the only thing that changes is the numbers. Over time you'll build a short library of client-friendly explanations that make your reports more useful without adding hours to your close.

Clients don't need you to stop being the expert. They need you to translate. AI can draft the translation; your judgment decides what goes out.

Handling the hard parts of the conversation

Sometimes the report includes something a client won't like — a loss for the month, a large uncategorized amount, or an expense that jumped. Your plain-English summary should still describe it neutrally. "Net income for the month was negative $1,200" is a fact. Whether that matters, and why, is a conversation you have with the client directly, using your judgment and what you know about their business.

I also suggest keeping the review items as questions. "We'd like to confirm what the $640 Uncategorized Expense was for" invites the client to help. "You have $640 of unexplained spending" sounds like an accusation. AI will follow whichever tone you put in the prompt, so put in the one you'd use in person.

Finally, keep a copy of the version you sent. Next month, when the client asks how September compared, you'll have both summaries side by side and can explain the change in the same calm, consistent language.

• Describe losses and swings neutrally; discuss meaning in person.
• Phrase review items as questions, not accusations.
• Keep each month's sent summary for easy comparison.
