NordFlux builds AI phone assistants for trade and construction businesses: the assistant answers every call, captures the request, trade, and property address, classifies emergency calls according to your rules, and brings in the on-call technician. It books site-visit and measurement appointments directly into your calendar. Whatever it doesn't resolve is ready in the evening as a sorted callback list, not a row of unknown numbers.
Between seven and four there's nobody in the office, because the team is on the construction site. Whoever is up on the scaffold or operating a machine doesn't pick up the phone, and the customer rarely tries a second time.
A phone assistant for a trade business needs to handle different things than one for a medical practice or an office. These five call types make up the lion's share of everyday calls.
The assistant picks up instead of the answering machine and asks structured questions: name, callback number, trade, property address, and what it's about. It distinguishes the private customer with the dripping tap from the site manager with a change order, so in the evening you find a list sorted by urgency and job type instead of a row of unknown numbers.
Impact no call lands on the answering machineBurst pipe, water damage, heating out in January, power outage, smell of gas: the assistant recognizes the keywords you define in advance and follows your escalation chain instead of noting down a callback. It puts the caller through to the on-call technician or sends the address and request to their phone as a message. In case of a gas smell, it immediately refers to the emergency number and the network operator and doesn't book an appointment.
Impact emergency gets through instantlyThe assistant knows your calendar and only offers appointments that fit the route, with a buffer for travel time. It captures the details your people need on site: property address, floor, access, on-site contact, and which trade is needed. The appointment is in the calendar before you're off the scaffold.
Savings 1–2 h per week of appointment coordinationWhen is my quote coming, are you really coming on Thursday, is the appointment still valid: these follow-up questions cost the business the most time and bring in no revenue. The assistant answers them straight away from your trade software or the calendar. What it doesn't know for certain it doesn't make up — instead it announces a callback and notes the question.
Impact follow-up questions resolved without a callbackThe wholesaler reports that the delivery is delayed, the driver asks about the time slot for the site delivery, someone wants to know which order number the goods are booked under. The assistant records delivery note and order number, time slot, and contact person in a structured way and forwards it directly to the responsible site manager, instead of letting it end up on a slip of paper in the van.
Impact material info reaches the site managerSpeech understanding, the connection to your systems, and clear rules interlock. We choose the tools based on your case, not on a partner program, and you define every rule.
The foundation is a voice agent that speaks naturally, can be interrupted, and follows fixed rules. What it may and may not do is up to you: it never commits to prices, doesn't offer appointments outside your route, and makes no promises about the scope of work.
Integrationn8n connects the assistant with the calendar, your trade software, and the callback list, and writes appointments and requests directly into your system. Where an interface is missing, you get structured lists wherever you already look. Only what each step needs is transferred, run on EU servers.
The assistant states at the start of the call that it's your business's AI assistant. From August 2, 2026, Article 50 of the EU AI Act applies, requiring exactly this disclosure for AI systems in direct contact with people. We build it in from the start instead of having to retrofit it later.
From the initial analysis to a running phone assistant in 30 days, at a fixed price instead of open timesheets.
In 60 minutes we look at how many calls come in for you, when they come in, and how many of them currently go nowhere. We also clarify which trade software is in use and how your emergency service is organized.
We define which keywords count as an emergency, who is on call when, and how the technician is reached. Added to that are the disclosure required under the EU AI Act and the assistant's limits. After that you receive a fixed-price quote.
We build the assistant, connect the calendar and callback list, and test real call flows with your people, including from the construction site with background noise. We check the emergency chain especially thoroughly, because nothing may get stuck there.
The assistant goes live step by step: first outside office hours, then as overflow when nobody answers. After 30 days it's running day-to-day, and you know how to change the disclosure, keywords, and on-call rules yourself.
Once calls are handled, it quickly becomes clear where things jam up further down the line: quote from the measurement, invoice on the day of acceptance, timesheets from the site. Process automation for trade businesses takes care of exactly this chain.
In the free initial analysis we work this out together in 60 minutes, no obligation and no jargon. Afterwards you'll know whether an AI phone assistant pays off for your business.
Yes, and that's expressly intended. The assistant states right at the start that it is your business's AI assistant and is taking down the request. From August 2, 2026, this is exactly what's required: Article 50 of the EU AI Act requires that AI systems speaking directly with people disclose that they are an AI. We build this disclosure in from the start, because it's coming anyway and because customers appreciate not being deceived.
The assistant recognizes the emergency keywords you defined in advance and follows your escalation chain instead of noting down a callback. Depending on the rule, it puts the caller through to the on-call technician or sends them the property address and request straight to their phone. In case of a gas smell, it refers to the emergency number and the network operator and doesn't book an appointment. You decide who is on call when and what counts as an emergency.
In most cases, yes. Wherever your trade software offers an interface, the assistant writes appointments, requests, and callback wishes directly into it, so your people keep working in the system they know. If there's no interface, you get structured lists in your calendar or inbox instead of slips of paper in the van. We clarify what's technically possible for you in the free initial analysis, before you commission anything.
Today's speech AIs cope well with background noise and regional accents, but not with everything. What matters more than perfect understanding is the behavior in doubt: the assistant asks again instead of guessing, and if it fails twice, it only takes down the callback number and keyword and hands over to a person. In testing we run through real calls with background noise so you know where the limit lies before going live.
Implementation runs at a fixed price, whose level depends on the scope: number of call types, emergency logic, connection to calendar and trade software. After the free initial analysis you receive this fixed price, no open timesheets. We'll also tell you honestly there if the assistant doesn't yet pay off for your call volume.
