Introduction
Many mobile shop owners are excellent salespeople and incredible hardware technicians, but terrible accountants.
Running a ₹5,00,000 per month retail business without understanding fundamental accounting principles is dangerous. You might see a lot of cash passing through the register, making you feel wealthy, while the business itself is secretly burning through your savings.
Here are the absolute basics of mobile retail accounting you must master.

1. Cash vs. Accrual Accounting
Cash Accounting This means you record revenue when the physical cash (or UPI transfer) hits your bank. You record expenses when you actually pay your supplier. This is the simplest method, and the one preferred by micro-shops. * *Example:* You buy ₹1,00,000 of accessories on credit on Monday. You don't record the expense until you pay the vendor on Friday.
Accrual Accounting This means you record revenue when you *earn* it, regardless of when you receive the cash. You record expenses when you *incur* them. * *Example:* You execute a ₹50,000 bulk repair for a corporate client on Monday with Net-30 payment terms. You record ₹50,000 in revenue today, even though the cash won't arrive for 30 days.
Accrual gives a much more accurate picture of your true monthly performance, but it requires diligent bookkeeping.

2. Cost of Goods Sold (COGS)
COGS is the direct cost attributable to the production or purchase of the goods sold by your company.
- ✦In a mobile shop, COGS includes:
- ✦The wholesale price of the smartphones you sold.
- ✦The wholesale price of the tempered glass screens you sold.
- ✦The cost of the exact OEM screens your technicians installed during repairs this month.
COGS does not include rent, electricity, or your technicians' salaries.
*Why it matters:* If your COGS is expanding faster than your revenue, your suppliers are raising prices without you passing those costs to the consumer. Your margins are actively bleeding.

3. Gross Profit vs. Net Profit (The Big Trap)
Gross Profit = Total Revenue - COGS If you sell ₹1,00,000 worth of phone cases this month, and they cost you ₹40,000 wholesale from Delhi, your **Gross Profit is ₹60,000**.
A common mistake is stopping here and assuming you "made ₹60,000."
Net Profit = Gross Profit - Operating Expenses (OPEX) OPEX is everything required to keep the lights on: Shop Rent (₹15,000), Electricity (₹5,000), Employee Salaries (₹25,000), WhatsApp API costs (₹1,000).
*Calculated Net Profit:* ₹60,000 - ₹46,000 = ₹14,000.
Your actual take-home pay is ₹14,000, not ₹60,000.

4. Accounts Receivable (AR) & Accounts Payable (AP)
- ✦Accounts Receivable (Money owed to you): If you fix 50 devices for a local school and invoice them on Net15 terms, that ₹40,000 lives in your AR. High AR means you are generating sales but failing to collect cash.
- ✦Accounts Payable (Money you owe): You purchased 500 charging bricks from your distributor on credit. That ₹25,000 lives in your AP. Managing AP ensures you don't use the cash you owe suppliers to wrongfully pay yourself a bonus.
