We built ops software for local delivery shops after watching one miss 129 of 130 calls in a day

I run Kamui, a small software company that builds the back office for local delivery businesses. Our customers are shops that take orders from marketplaces and their own site, dispatch drivers, and live on their phones and text messages.

What started this was simple. We pulled the call logs for one of our shops and found 130 call attempts from 43 customers in a single business day. One was answered. Nobody was lazy. The phone rang on a browser tab that had quietly disconnected, the manager was texting three customers at once, and the driver app knew things the front desk didn't.

So we built the boring, connected version of a delivery shop:

- One inbox for everything. Marketplace orders, website orders, texts and calls land in one dashboard instead of five tabs.

- A phone that rings in the browser, and when nobody picks up, an AI assistant answers. It tells callers where their order is, answers menu questions from the live menu, and takes a message for anything it shouldn't decide. New customers confirm their order in writing, so a misheard address never sends a driver to the wrong place.

- Drivers, routes and ETAs that the phone, the texts and the customer all see the same way.

- A storefront per shop that reads the same menu, prices and delivery zones as the dashboard, so the website never promises what the shop can't deliver.

- Receipts, label printing and texting handled by a small app on the shop's own Mac.

Some things we learned the hard way:

- The most expensive bug was a phone that looked connected.

- Customers forgive a slow answer. They don't forgive an order to the wrong address.

- AI is great at "where is my order" and bad at refunds. Let it do the first and hand the second to a person.

- Cheap AI models handle most of the work. Our bill dropped hard once we stopped sending the whole menu to the model on every text.

We're still small and work closely with every shop. If you run a local delivery operation and want to compare notes, or think something here is wrong, I'd like to hear it.
