Choosing Between a Kirana Store and a Mobile Repairs Counter
Ravi, 24, has saved ₹3 lakh and can borrow ₹5 lakh under a state scheme at 9% simple interest, repayable over 5 years. He is choosing between (a) a kirana and daily-needs store and (b) a mobile accessories and repair counter, in a town of 45,000 people. Option (a): 400 sq ft shop at ₹18,000 rent, ₹1.2 lakh fittings, ₹3.5 lakh opening stock, 18% average gross margin, one helper at ₹9,000, electricity ₹4,000, other fixed costs ₹5,000. Option (b): 200 sq ft shop at ₹12,000 rent, ₹2 lakh fittings, ₹2.5 lakh stock, 32% gross margin on accessories and 55% on repairs, with repairs expected to be 30% of revenue; one technician at ₹16,000, electricity ₹3,000, other fixed ₹5,000. Nearby there are already four kirana shops and one accessory shop. The loan EMI is about ₹10,400 a month.
1. Calculate the monthly break-even sales for both options. Show the fixed-cost build-up and the contribution margin.
Read the worked answer
Fixed costs (both include the EMI of ₹10,400)
- Option A: 18,000 + 9,000 + 4,000 + 5,000 + 10,400 = ₹46,400
- Option B: 12,000 + 16,000 + 3,000 + 5,000 + 10,400 = ₹46,400
Contribution margin
- A: 18% of sales.
- B: accessories 70% of revenue × 32% = 22.4; repairs 30% × 55% = 16.5 → blended 38.9%.
Break-even sales
- A: 46,400 ÷ 0.18 = ₹2,57,778 a month ≈ ₹8,593 a day
- B: 46,400 ÷ 0.389 = ₹1,19,280 a month ≈ ₹3,976 a day
Interpretation: Option B needs roughly ₹4,000 of daily sales; Option A needs roughly ₹8,600. At an average repair job of ₹150 plus accessory sales, B can reach its break-even with around 25–30 jobs a day plus walk-in accessory sales - a realistic target in a town of 45,000 if he can repair well. Option A requires the store to sell nearly ₹2.6 lakh of groceries a month at a thin margin while carrying perishables, spoilage and credit sales.
Check Ravi's own drawings: neither figure includes his living expenses. Add ₹15,000 a month and B's break-even becomes (46,400 + 15,000) ÷ 0.389 ≈ ₹1,57,840 a month, about ₹5,261 a day - still far below A's revised figure of (61,400 ÷ 0.18) ≈ ₹3,41,111 a month.
2. Which option should Ravi choose? Give your recommendation with the risks, and state what he must verify before signing the loan.
Read the worked answer
Recommendation: Option B, conditional on repair skill. The gap in break-even is decisive - roughly ₹4,000 a day versus ₹8,600. A lower break-even is a bigger cushion: a slow week threatens less, and the loan is easier to service from month one.
Reasoning for B
- Higher blended margin (38.9% vs 18%) means each rupee of sales contributes twice as much to fixed costs.
- Small stock, fast rotation, low spoilage. A 200 sq ft shop is cheaper to run and exit if it fails.
- Repairs are a service a kirana cannot copy, and one existing accessory shop means one competitor, not four.
Risks in B
- Skill dependency: the entire margin story collapses if the technician leaves or repairs fail. Ravi should personally learn basic repairs, or structure the technician's pay partly as a share of repair revenue.
- Obsolescence: accessories lose value fast. Keep stock cover at 30–45 days and negotiate credit, not bulk discounts.
- Existing competitor: differentiate on same-day repair, warranty on work, and stocking for all major phone brands.
Risks in A that Ravi must not underestimate: four established kirana shops, price wars on staples, credit sales to neighbours, and spoilage. Its lower margin leaves almost no room for error.
Verify before signing
- Footfall at both sites, counted in person on a weekday and a Sunday.
- Rent agreement terms, deposit and escalation.
- Loan processing fee, actual repayment schedule, and whether the state scheme requires a guarantor or collateral.
- Competitor pricing for repairs and accessories within a 2 km radius.
- That total outlay (fittings + stock + deposit + 3 months' fixed costs) fits within ₹8 lakh - B needs about ₹2 lakh + ₹2.5 lakh + deposit, which leaves a working-capital buffer; A does not leave much.
3. What registrations, records and first-90-days controls should Ravi put in place, and why does each matter to a small retailer?

Registrations
- GST: required once turnover crosses the threshold (₹40 lakh for goods, ₹20 lakh for services in most states); a repair counter that also sells goods should register and charge the correct rate on each. Without it, he cannot claim input credit, and the shop cannot sell to any business customer.
- Shop and Establishment registration with the municipal body or labour department - the basic proof that the shop is legal.
- Trade licence from the municipality if required locally, plus Udyam registration to access the scheme benefits and easier credit.
- Current account in the business name, and a UPI merchant QR - customers now expect it, and it leaves a clean record.
- E-waste / battery handling for the repair counter: disposal through an authorised recycler, not the bin.
Records
- Daily cash book and a simple billing system; separate business and personal cash from day one.
- Stock register with purchase date, supplier invoice, and warranty terms for parts used in repairs.
- Repair job cards: customer name, phone, IMEI, fault, quoted price, customer signature, and a note that the customer must back up data.
First-90-days controls
- Compare actual daily sales with break-even (₹5,261 including drawings) every week; act in week 4, not month 6.
- Do not let stock cover exceed 45 days, and review slow items monthly.
- Keep three months of fixed costs in reserve - a promising shop often fails in month two because the cash is all in slow stock.
