Sellavie.ai payment gateway: where chat met checkout
Payment-gateway work, frontend checkout changes, and the first big step from messaging automation to commerce automation.
This was where Sellavie became more than a conversation tool.
When chat connects to payment, the product has to stop being casual. A message can lead to an order. An order can lead to an invoice. An invoice can lead to a payment status. The backend has to own that state carefully, and the AI has to know when it is operating near money.
What changed
The payment-gateway work touched both backend and frontend. That matters because payment features are not just provider calls.
They change what the customer sees at every step, what the business owner trusts enough to act on, what the system records for reconciliation, and what the AI should or should not say next in the conversation thread.
An AI that continues selling after a payment has failed is annoying. One that congratulates a customer on a purchase that did not actually complete is a support problem. Getting the state transitions right here is the whole product.
The boundary
An AI sales tool has to know when a conversation becomes a transaction, and it has to yield control at that point rather than improvising.
That boundary — conversation on one side, transactional state on the other — is where the interesting design decisions live. Getting it wrong shows up immediately as customer confusion and support volume.
