A model is not a system. We build the rest.

nullfield.ai builds automation and AI agents for mid-sized companies: order processing, bookkeeping, sales research. The systems below are running in production.

+ // Running

01

Order to invoice, for a food mail-order business

Task
Orders arrive through the online shop and by phone. Each needs a packing list, a shipping label, an invoice and a confirmation.
System
One web application takes every order through all steps and transfers the invoices to the accounting software.
Status
In daily operation since autumn 2026. Automated tests check every change.
02

Sales and market monitoring for B2B companies

Task
A sales team wants to know which target companies matter right now and what is moving in its market.
System
Several modules on one shared data core. One finds and tracks target customers, one tracks the market, others produce content and maintain contacts. Customers read and correct everything in a web portal.
Status
In production. The sales briefing arrives weekly, the market briefing monthly.
03

Receipt bookkeeping

Task
Photograph receipts instead of typing them in, and never miss an open payment.
System
The photo arrives by messenger, an AI reads the receipt and creates a draft with a suggested account in the accounting software. A weekly run matches it against bank transactions.
Status
Capture in production. Nothing is booked until a person approves it.

+ // How

Context.

The model gets what a good employee would need for the task: company data, rules, history.

Memory.

Results and corrections are stored in the database. The next run reads them instead of guessing again.

Tools.

Where a model would guess, it looks things up: in the shop, the registry, the accounting system.

Data flows.

Every value has a producer and a reader. What nobody reads does not get built.

Cross-checking.

A second model checks what the first produced. What fails the check does not go out.

A person decides.

Anything that moves money or leaves the building is confirmed by someone.
