Core features.
One application for the whole business, from the freezer to the settled balance.
Orders and fulfilment
Multi-item orders move from pending to ready to closed, selling loose pieces or full boxes at the box price.
Payments and debt
Sales run unpaid, partial, paid. A debt payment is allocated first-in, first-out across a customer's outstanding sales, with a reprintable receipt.
Cash flow and reconciliation
Admin reports cover cash flow and profit, daily expected-versus-actual reconciliation per channel, expenses and owner drawings.
Ms Poundz, the ordering assistant
Customers order in natural language on WhatsApp, Instagram or the storefront chat, and receive a link to confirm.
A public storefront
The virtual shop lets visitors browse the frozen range and start an order with the assistant.

Innovation highlights.
Innovation one
A draft is not an order
The assistant can only create a draft. It becomes a pending order when the customer confirms on a single-use page with a 24-hour token, keeping a human handoff between conversation and fulfilment.
Innovation two
Answer Meta in time, think afterwards
The webhook verifies the HMAC signature, stores the message and returns 200 immediately. The agent runs after the response with Next.js after(), so no worker queue is needed.
Innovation three
One agent, three channels, two models
WhatsApp, Instagram and web chat share one conversation model and one agent loop. OpenAI or Anthropic sits behind a shared runner interface, switched by one setting.
