# Seasonality Analysis by Quarter

> Use Layer MCP report tools to compare quarterly trends and seasonal business patterns.

An AI assistant can compare quarterly financial patterns to help a business owner understand seasonality. This is useful for businesses with recurring busy seasons, slower periods, or expense cycles that change throughout the year.

## Questions And Uncertainties

Business owners often want to understand:

* Which quarters are usually strongest or weakest.
* Whether a slow quarter is expected seasonality or a new problem.
* Whether expenses rise before or during busy seasons.
* Whether profit changes are driven by revenue, cost of goods sold, or operating expenses.
* Whether the current quarter is tracking better or worse than prior quarters.

## Prompts And Tools

Users can ask prompts like:

* "Which quarter is usually strongest for revenue?"
  This typically triggers `get_profit_and_loss_summaries`.
* "Do my expenses rise before my busy season?"
  This typically triggers `get_profit_and_loss_summaries`.
* "Compare this quarter to the same quarter last year."
  This typically triggers `get_profit_and_loss_summaries`.
* "Are seasonal changes coming from revenue or expenses?"
  This typically triggers `get_profit_and_loss_summaries`.

## Expected Interactions

The agent should retrieve a month range wide enough to compare quarters, group monthly results into quarters, and explain the seasonal pattern. If the data is sparse or uncategorized activity may distort the results, the agent should say so and suggest reviewing the underlying transactions.

## Details And Variations

Seasonality analysis can compare consecutive quarters, the same quarter across years, or busy-season months against off-season months. The assistant can focus on top-level metrics such as revenue and net profit, or drill into cost of goods sold and operating expenses when the user wants to understand what changed.

This type of analysis works best when the business has enough categorized historical data for quarter-over-quarter comparisons.
