Fish restaurants on the shores of Lake Sapanca in northwest Turkey turn over 80+ tables during evening service — waiter shortages stretch order-taking to 12 minutes per table. Affiliate Sahin closed four restaurants in six weeks by emphasizing thMenu Platinum's built-in table ordering plus table sessions, rather than Adisyo Online's add-on bundle structure.
Pricing: Add-On vs Built-In
Adisyo Online sells table ordering as a separate module — on top of the base POS subscription, the "Online Order" package adds roughly 350-500 TRY per month. For a 60-table Sapanca operator, that equals about 1,200 TRY extra monthly.
thMenu Platinum tier at $59/month (~1,950 TRY) bundles table ordering, table sessions, order tracking, waiter calls, bill requests, AI product details, and unlimited tables. Sahin's pitch: "You pay for two features and get three more for free."
Table Sessions: Sapanca's Hidden Weapon
At a Sapanca fish restaurant a single table seats 8-10 guests for 3 hours. Adisyo Online treats every order independently — who ordered what becomes chaotic, and splitting the bill is a nightmare. thMenu's table session starts with a QR scan and uses a 1-hour TTL to merge all orders from that table into one bill.
Sahin's pitch line: "Press 'Request Bill' — the host device terminates, no waiter chasing leftover sandwiches one by one." The Yıldız Balık restaurant in Sapanca cut adisyon errors 73% during evening service after switching.
Server-Side Price Validation and Idempotency
Adisyo Online relies on client-side cart pricing, which exposes daily-fluctuating fish market prices to manipulation. thMenu's order POST reads canonical price from D1_MENU and silently overwrites mismatched client unit_price values.
- Idempotency-Key header per cart via crypto.randomUUID() — zero double-tap duplicates
- db.batch atomic INSERT — no half-written orders with missing order_items
- Shadowban list filters fake-GPS customers automatically
Sahin's fourth close, Köprübaşı Restaurant in Adapazarı, migrated from Adisyo three weeks ago citing this single feature as the deciding factor.
FAQ
Can Adisyo POS customers move to thMenu? Yes — Adisyo POS can stay at the cashier. thMenu runs as the menu + table ordering layer only. Sahin tells prospects: "We don't replace your POS, we upgrade the customer-facing side."
How does affiliate commission work? 20% lifetime — four customers on Platinum yearly ($590) yields ~$472/year commission per account, dripped over 12 months. Four customers = ~$1,888 annual passive income.
Does this pitch work outside Sapanca? Absolutely. Beyşehir, Bafa, Eğirdir, and Salda lake regions share the same 60-100 table plus long-dwell-time pattern. Sahin's case study is copy-paste replicable.
