# Your first business cycle

Follow one real product through a normal business cycle. You will set it up, buy stock, sell for immediate and later payment, and then review what changed.

> **Interactive journey**

> [Start or continue the interactive journey in Dukarun](https://app.dukarun.com/learn/first-business-cycle). It resumes from your last task.

## Before you start

Choose a product your business genuinely buys and sells. Have one supplier invoice or delivery note nearby. Use a customer you know well enough to make a sensible credit decision.

Do not use invented balances in a live business account. If you only want to practise, use a test company.

## Video

The task-specific walkthrough is being prepared. For now, watch this Dukarun overview.

2. [Create a supplier](/docs/suppliers/creating-a-supplier.md).
3. [Record a credit purchase](/docs/purchases/recording-a-credit-purchase.md).
4. [Complete a cash sale](/docs/selling/making-a-cash-sale.md).
5. [Create a customer and set credit](/docs/customers-and-credit/creating-a-customer-with-credit.md).
6. [Complete a credit sale](/docs/selling/making-a-credit-sale.md).

## What each task changes

| Task                     | What changes                                                                              |
| ------------------------ | ----------------------------------------------------------------------------------------- |
| Create a product         | The item and its sellable variant become available for purchases and sales.               |
| Create a supplier        | Purchases, payments, and unpaid supplier balances can use one supplier account.           |
| Record a credit purchase | Stock increases and the unpaid amount becomes a supplier payable.                         |
| Complete a cash sale     | Stock falls, cash received increases, and Dukarun records revenue and cost of goods sold. |
| Set customer credit      | The approved customer can buy within the saved credit policy.                             |
| Complete a credit sale   | Stock falls and the unpaid amount becomes a customer receivable.                          |

## Review the result

After the six tasks, open the financial recap. It points to the real Dashboard, **Money > Credit**, and **Reports** views for stock, cash, payables, receivables, revenue, cost of goods sold, and margin.
