How to earn 3000 TL extra monthly while in university (Turkey)

When Defne, a third-year industrial engineering student at Boğaziçi University in Istanbul, decided she wanted to live in Etiler without asking her family for allowance, she had zero side-hustle experience. Eighteen months later she pulls in 870 TL per month working only six hours a week — not by freelancing or food delivery, but by enrolling 12 cafes around campus into the thMenu affiliate program.

The 6-hour weekly routine

Defne's schedule is simple and disciplined. Monday and Wednesday evenings from 7-9 PM she visits one or two new cafes near campus and has a 10-15 minute introductory chat with the owner. Saturday mornings 9-11 AM she handles existing clients' WhatsApp questions and reviews monthly performance reports. Total: six hours a week — less than a research paper.

The reason this rhythm is sustainable is that there's no "sales pressure." Defne doesn't quote prices on the first visit. She just demonstrates the QR menu working on her own phone and says, "If you'd like, I have a $5 discount coupon to start with." Soft sell, real value.

12 cafes × $5.80 lifetime = 870 TL/month

At the 18-month mark Defne has 12 active restaurant accounts. All are on the Pro plan ($29/month), and with the 20% lifetime commission she averages $5.80 per cafe per month. 12 × $5.80 = $69.60 ≈ 870 TL — roughly half a student's rent in Etiler or a month of groceries.

• Weeks 1-12: first 3 cafes signed, monthly income reaches 217 TL
• Weeks 13-52: 7 more cafes added, monthly income climbs to 580 TL
• Weeks 53-78: final 2 cafes plus zero churn settles routine at 870 TL

Why owners say yes

Defne's pitch isn't aggressive. She sits at the cafe, orders her coffee, and tells the owner, "I can explain a way to digitize your menu in three minutes if you're interested." The 5% Stripe coupon she offers makes owners feel they're supporting a student while also getting a real discount — a double psychological hook.

The second reason: Defne handles all the technical onboarding herself. She prints the first QR, uploads menu photos, organizes categories. The owner only says yes — a 30-minute effort on her side translates into years of passive income.

FAQ

How is this taxed in Turkey? 870 TL monthly falls under the "simple bookkeeping" regime; Defne files an annual return with an accountant who charges 1500 TL/year.

What if a cafe closes? Commission for that cafe stops, but lifetime rules mean previous months are never clawed back. Defne's 18-month churn is zero.

What about exam weeks? She cancels Monday/Wednesday visits and spends only 30 minutes on Saturday answering WhatsApps. The existing income stream keeps flowing untouched.
