What problem does it solve?

SMEs mostly answer WhatsApp messages by hand and late. The same questions, such as price, stock, address, opening hours and shipping status, are asked over and over all day. Messages that arrive after hours wait until morning and the customer goes elsewhere. Orders stay scattered across chats and it becomes unclear who wanted what. When several employees share the same phone, replies become inconsistent and no records are kept. Simple menu bots cannot understand questions customers type freely, which often makes for a frustrating experience.

Target customers

  • Boutiques and online stores
  • Restaurants, cafes and delivery businesses
  • Clinics, hair salons and beauty centers
  • Auto repair and technical service businesses
  • Educational institutions and courses
  • Travel agencies and small hotels

How the product works

The business connects its WhatsApp Business Platform number to the system and enters its product/service list, prices, promotions and FAQs in the dashboard. The AI assistant understands every incoming message, generates a reply from the business's knowledge base and sends product cards, locations or buttons when needed. In the order flow it collects product and address details; in the appointment flow it suggests available times from the calendar. Conversations the assistant is unsure about or that contain complaints land in a shared inbox where an employee takes over. All conversations, orders and appointments are reported in the dashboard.

What the first version (MVP) needs

  1. WhatsApp Business Platform connection: Number and template message management via the official API
  2. Knowledge base: Upload product, service, price and FAQ content from the dashboard
  3. AI replies: Understand free text and generate knowledge-base-grounded answers
  4. Order taking: Collect product choice, address and notes and push them to the dashboard
  5. Appointment booking: Suggest available times from the calendar and send a confirmation
  6. Shared inbox: Hand conversations over to staff and tag them
  7. Reporting: Conversation, order and handover statistics

Revenue model

  • Monthly subscription: Plans based on conversation volume and number of users
  • Setup service: Knowledge base preparation and flow design
  • Integration add-ons: E-commerce, inventory and bookkeeping connections
  • Agency/reseller license: White label for digital agencies to sell to their own clients

Why now?

WhatsApp has become one of the channels customers in Turkey prefer most for contacting businesses. The official WhatsApp Business Platform opening up to small businesses, together with language models that can now reliably understand free text, makes assistants that go beyond menu bots possible. In Europe too, sales and support over messaging are spreading quickly. Because SMEs find it hard to access this technology on their own, a service that is simple to set up, Turkish-focused and offers industry-specific templates fills a clear gap.

End-to-end roadmap

  1. Validate the idea (1 week): Interviews with target customers, competitor and pricing research; we sharpen the idea together in a free pre-analysis.
  2. Scope and design (1–2 weeks): MVP feature list, screen designs and technical architecture; written scope and quote.
  3. Build the MVP (6–10 weeks): Staged development with weekly demos and a test environment; the source code belongs to you.
  4. Pilot (2–4 weeks): Real use with the first customers, feedback and fixes.
  5. Launch and grow (ongoing): App Store and Google Play release, website and SEO, payments and subscriptions, new modules.

Timelines are estimates; they are fixed in a written quote once the scope is clear.

Risks and how to handle them

  • WhatsApp policy and pricing changes: Use the official API, follow Meta's business messaging rules and reflect conversation fees in your pricing
  • Giving wrong information: Limit answers to the business's knowledge base, pull data like price and stock from a live source, and hand over to staff when in doubt
  • KVKK and personal data: Provide customers with a privacy notice, obtain separate consent for marketing messages and set a retention period for conversation data

Frequently asked questions

Does it work with the regular WhatsApp Business app?

Automation requires access to Meta's official WhatsApp Business Platform (API). The number is moved to this platform and messages are managed through the API.

Will the chatbot quote a customer the wrong price?

If the assistant is designed to pull price and stock from live data and rely only on the business's knowledge base, this risk is greatly reduced; when unsure, it hands the conversation over to an employee.

What is needed to send promotional messages?

Business-initiated messages require templates approved by Meta and the customer's consent to receive commercial messages. Consent records should be stored in the system.

Which industry makes sense to start with?

Industries with frequently repeated questions and an appointment/order flow, such as clinics, hair salons and restaurants, are good starting points for fast sales with ready-made templates.
