What is a WhatsApp commerce bot?
A WhatsApp commerce bot lets customers browse a catalogue, build an order, pay and track delivery inside WhatsApp, using the Business API. Stack18 builds it with ERP or store integration, payment links and handover to staff, and focuses it on repeat and B2B ordering where WhatsApp is already the habit.

Discovery
We map today's process, systems and data for catalogue and search; cart and order capture; and payments, talk to the people who run it and agree the baseline for order entry time and orders via WhatsApp so progress is measured from week one.
Design
We design the flows, roles, approvals and integrations for catalogue and search; and cart and order capture, and review a clickable prototype with the people who will use it before anything is built.
Build in weekly demos
We build in weekly demos, starting with catalogue and search, then cart and order capture and payments. Each release is tested on your own data and passes a human approval gate before the next begins.
Launch and support
We migrate data, train your team and support go-live. After 30 days we review order entry time, orders via WhatsApp and status queries to staff against the baseline and agree what to extend next.
Start small. Scale when it works.
Every engagement begins with a short, fixed-price step so you can judge the fit before committing further. See pricing.

WhatsApp Commerce Bot questions.
Is this for B2B or consumers?
Both. B2B repeat ordering is often the strongest fit, because customers already use WhatsApp with their suppliers.
Can it show customer-specific prices?
Yes, if prices come from your ERP or price lists. You see a fixed price and a clear scope before you commit, and changes follow an agreed process.
Do we need the WhatsApp Business API?
Yes. We help set up the number, templates and approvals. Messages use approved templates and recorded opt-ins, and provider fees are shown upfront.
Can orders go into our ERP?
Yes. Orders post to your ERP, store or CRM automatically.
What if the customer needs help?
The bot hands the chat to your team with the order context.
How do you measure success for WhatsApp Commerce bot?
In week one we agree a baseline for order entry time, orders via WhatsApp and status queries to staff. We report them at every weekly demo and review them against the baseline 30 days after go-live, so results are measured rather than assumed.
What should we prepare before the first call?
Bring a short description of how WhatsApp Commerce bot works today, examples of the documents or screens your team uses, and the three numbers that matter most to you. A senior specialist will use them to outline a first step and a fixed price.
