1. Objectives

By the end of this module you will be able to:

1. Sort any financial item in your store into: asset / liability / equity / revenue / expense — without hesitating.
2. Write the accounting equation and check that it balances on any set of numbers.
3. Tell cash from profit, and explain why your store can be profitable and go bust at the same time.
4. Draw the cash cycle of an e-commerce store, from paying the supplier to the money reaching the bank, and pinpoint where the cash gets stuck.
5. Name the five fatal mistakes common in young store accounting before you make them.

2. Core concepts

2.1 Only five boxes

Every number in every company on earth falls into one of five boxes:

Sorting rule: if the benefit is in the future it is an asset. If it has been used up it is an expense.
Rent paid 6 months in advance = an asset on the day you pay it, turning into an expense month by month.

2.2 The accounting equation

Assets  =  Liabilities  +  Equity

In expanded form, which explains why equity changes:

Assets = Liabilities + Capital + (Revenue − Expenses) − Drawings

This equation never breaks. If it breaks on you, you made the mistake — it did not.

2.3 Cash ≠ Profit

The most dangerous misunderstanding founders have. Two examples from Nuwa:

• On 3 January Nuwa bought inventory for 60,000 dirhams. Profit did not drop by a single dirham; one asset (a supplier payable, later) turned into another asset (inventory). The expense appears only when the goods are sold.
• In January Nuwa earned a profit of 24,312 dirhams, but operating cash coming in was only 8,853.60 dirhams. The difference was swallowed by inventory and prepaid rent.

A growing e-commerce store almost always has more profit than cash, because growth means buying more inventory before you sell it.

2.4 The cash cycle in an e-commerce store

You pay the supplier  →  you wait for shipping and clearance  →  inventory in the warehouse
     →  you spend on advertising  →  the customer buys  →  the money sits at the payment gateway
     →  settlement after 3–14 days  →  less the fees  →  the bank
     →  then returns are deducted after 14–30 days

Cash conversion cycle = inventory days + gateway collection days − supplier credit days.
For Nuwa in January: inventory sat ~30 days, the gateway ~7 days, the supplier gave 30 days of credit ⇒ the cycle ≈ 7 days. Acceptable. Had the supplier cancelled the credit it would have jumped to 37 days and the company would have needed extra working capital immediately.

2.5 The five fatal mistakes

3. A worked example, step by step

The question: on 5 January 2026, after only the first four transactions, where does Nuwa stand financially?

Step 1 — list the transactions:

Step 2 — sort each side into its box:

Step 3 — total each box:

• Bank = 150,000 + 50,000 − 9,000 = 191,000
• Inventory = 60,000 + 9,000 = 69,000
• Total assets = 260,000
• Liabilities = 50,000 + 60,000 = 110,000
• Equity = 150,000

Step 4 — check the equation:

260,000  =  110,000 + 150,000  ✓

Step 5 — read the result: there is no revenue and no expense yet ⇒ profit is zero. The company turned 69,000 dirhams of available cash into inventory. That is not a loss, it is an asset changing shape. And notice: transaction 4 was not a shipping expense — shipping and customs are part of the cost of the inventory, and that is fatal mistake number 5 avoided.

4. Exercises

Write your answers in the Exercise-M1 sheet of thenibras-academy-workbook.xlsx. For the solutions, email us at info@thenibras.com once you have tried it.

E1.1 — Sorting (beginner). Sort each of the following into asset / liability / equity / revenue / expense:
(a) a balance stuck in an Amazon Seller account — (b) VAT collected from customers and not yet paid — (c) the annual Shopify subscription paid in advance in January — (d) goods in the warehouse — (e) payment gateway fees — (f) an amount the founder lent the company — (g) profits that have not been distributed — (h) discount coupons given to customers.

E1.2 — Complete the equation (beginner).

E1.3 — The effect of transactions (beginner→intermediate). For each transaction, say which two boxes are affected and in which direction:
(a) selling goods costing 69 for 199 in cash — (b) receiving an advertising invoice that has not been paid — (c) paying the supplier's invoice — (d) a customer returning an undamaged product and getting a refund — (e) the founder withdrawing 5,000 dirhams for personal use.

E1.4 — Cash versus profit (intermediate). A store sold 200,000 dirhams in March and earned a profit of 30,000 dirhams, yet its bank balance fell by 40,000 dirhams. Give three different possible explanations, and show how you would check each one.

E1.5 — The cash cycle (intermediate). A store: inventory sits 45 days, the gateway transfers after 10 days, the supplier grants 15 days of credit. Calculate the cash conversion cycle, then show the effect of a successful negotiation that raises supplier credit to 45 days, and how much working capital that saves if daily purchases are 4,000 dirhams.

5. Mini project — "The opening balance sheet for your store"

Deliverable: one sheet in a spreadsheet file + a 5-line explanatory paragraph.

What is required:

1. Pick a store — your real one if you have it, or a fictional one you design yourself (not Nuwa).
2. Write a list of everything the store owns today (assets) and everything it owes (liabilities), with realistic numbers.
3. Calculate equity by subtraction, not by guessing.
4. Add a "source of the number" column for every item: bank statement / invoice / physical count / estimate. Flag every item whose source is "estimate".
5. Write, in 5 lines: your biggest asset, your biggest liability, and where you expect your cash to get stuck over the next 90 days.

Acceptance criteria:
- [ ] The equation balances exactly (a difference of zero, not "close").
- [ ] Every item sits in one box only.
- [ ] No personal item is mixed in with company assets.
- [ ] Every item sourced from an "estimate" is flagged explicitly.

7. Completion standard

Do not move to Module 2 before achieving all of the following:

Mastery level (optional): calculate the cash conversion cycle for your real store using actual figures from your bank statements, and identify the one number that, if improved, would cut your working capital need more than any other.
