A connected process
Your company doesn't need another program.
Your company doesn't need another program.
It needs its systems to work together.
An example of how a connected process can look: an order arrives by email and spreads through your company's systems on its own. Doubtful cases are decided by a person.
Before
- By handOrder received by emailSomeone reads it and copies it into the ERP.
- By handERP and CRMSomeone else updates the CRM, when they can.
- By handNotice to productionProduction is told by email or phone and checks what is in stock.
- By handExceptionsThey are settled by phone and are not recorded.
Every handover depends on someone remembering.
After
- Order receivedArrives by emailIt comes in through the channel you already use, with nobody having to copy it.
- ValidationData and termsData, amounts and terms are checked against the company's own rules.
- AutomationNexus orchestrates the flowIt applies the rules, passes the information on and notifies whoever needs to know.
- Systems updatedEach system receives the information it needs, without anyone retyping the same data.
- ERP
- CRM
- Production
- Invoicing
Human review. If something doesn't add up or the case is doubtful, the flow doesn't decide alone: it hands it to a person.
Tasks that stop being manual
Copying the order from the email into the ERP, retyping the same data into the CRM, notifying production and preparing the invoice.
Decisions that stay with people
A figure that doesn't match, an unusual amount, a customer exception. The system prepares the case; whoever has business judgment decides.
Systems involved
The ones you already use: email, ERP, CRM, production and invoicing. Nexus connects them with its own software.

The problem
The work you don’t see
The work you don’t see
is also costing you money.
Your team shouldn’t act as a bridge between your systems. Every time someone copies, checks, chases or re-enters information, there is a process worth reviewing.
Unnecessary waiting
A process stops because a notice or a validation is missing.
Avoidable errors
Manual tasks generate corrections and rework.
Dependence on people
The process gets blocked when the person who knows the procedure is away.
Not all of these problems need AI. All of them deserve to be measured before investing.
Calculator · Operating cost
How much does this process cost you?
Four inputs and one number, in about 15 seconds. The calculation runs in your browser: nothing is sent to any server and we don’t ask for your email.
The starting values (3 people, 10 hours, €25 an hour and 46 weeks) are illustrative, not client data. When you press “Request a diagnosis” they are carried to the form, but nothing is sent anywhere until you send it.
The method
First we understand.
First we understand.
Then we build.
Five steps, always in the same order, so you decide with information and not with promises.
01Diagnose
We analyse a process, its tools, owners, timings and points of failure.
02Quantify
We estimate the current cost and the potential benefit with explicit assumptions.
03Design
We choose the simplest solution that solves the problem, whether software, integration, automation or AI.
04Implement
We build, test with real cases and set up controls for errors and exceptions.
05Measure
We compare the result with the starting situation and document the system.

Illustrative examples
What we build,
What we build,
by type of problem.
From several disconnected systems to an integrated operation.
- Scenario
- Industrial manufacturer of about 60 employees, with ERP, CRM and spreadsheets.
- Problem
- Orders are copied by hand between systems and production works with yesterday’s data.
- How we approach it
- Integration between ERP, CRM and production, and an agent that distributes orders using the company’s rules.
- How it is measured
- Hours of copying per week, orders with errors and time between order and manufacturing order, before and after.
From manual administrative work to automatic execution.
- Scenario
- B2B logistics operator of about 40 employees that receives orders by email, portal and phone.
- Problem
- Someone consolidates the orders by hand and exceptions are settled by phone without being recorded.
- How we approach it
- Reading orders from email and documents, checking stock and assigning a carrier with its own rules; exceptions reach the right person, recorded.
- How it is measured
- Orders that come in without typing, recorded exceptions and response time to the customer.
A process that depended on people, turned into a system.
- Scenario
- Services company of about 30 employees whose customer onboarding process only one person masters.
- Problem
- The knowledge is in one head and every onboarding jumps between three tools.
- How we approach it
- Document the process, automate the repetitive steps and leave the judgement in written rules.
- How it is measured
- Onboarding time, manual steps and dependence on a single person.
These are typical scenarios: they are not specific clients and do not include real results. The data of real projects is under NDA; when a client authorises it, we publish the case. See the full examples.

This is what we deliver.
A complete operations audit report on a simulated company: map, problems with their cost, prioritisation, 90-day roadmap and ROI estimate with explicit assumptions. All the data is simulated.
Why Nexus
The people who understand the problem are the ones who build the solution.
We read every request, sign every NDA and deliver every project in person: custom software, AI agents, training and business growth. That is why we work with a maximum of seven active projects: it is not marketing, it is our calendar.

Entry offer
Operations audit.
We identify where your company may be losing money, estimate its cost and define what is worth improving before investing in development.
What you receive
- Operating map. How work flows today, step by step, and who is involved in each step.
- Problems detected. Duplications, manual tasks, systems that don’t talk to each other and knowledge trapped in people.
- Estimated cost. What each problem costs, calculated with your numbers.
- Opportunities. Where automation, software or AI make sense, and where they don’t.
- Prioritisation. Ordered by impact on your bottom line.
- 90-day roadmap. What to do, in what order and with what resources.
- ROI estimate. With your own data, no empty promises.
The report is yours, whatever you hire afterwards.
What can raise the price
- How many processes or areas are included in the analysis.
- How many systems have to be mapped.
- The quality of, and access to, the data.
- Travel, if needed.
You receive the exact price in writing before we start, once your case has been studied.
See price ranges by type of project
| Typical projects | Indicative range |
|---|---|
| Automating a process | €2,500 – 7,500 |
| Enterprise AI agent | €5,000 – 15,000 |
| Internal system / application | €10,000 – 30,000 |
| Custom ERP / platform | €30,000 – 100,000+ |
| Industrial integration | Tailored |
| AI training for companies, per person | From €1,500 |
Indicative ranges to give you a first reference: the firm quote comes after the audit. Replacing a generic ERP entirely with a custom system runs between €80,000 and €180,000 (how much custom software costs), and AI agents have their own breakdown (how much an AI agent costs).
Hypothetical example: if solving a problem costs €10,000 and that problem costs you €50,000 a year, the conversation changes.
Before you ask.
What size of company do you work with?
Mainly companies of between 20 and 500 employees where automation, software or AI can produce a real economic impact. For freelancers and small businesses there is a separate line, with a single AI agent and its own capacity.
What kinds of problems can you solve?
The ones that repeat and cost time: orders that are copied between systems, notices someone has to give by hand, duplicated data, processes only one person knows how to do. Depending on the case, the solution is custom software, an integration, an automation or an AI agent; sometimes it is enough to change the process.
Do I need to know which technology I need?
No. We prefer that you tell us the problem. We then decide whether the solution is software, automation, AI, integration or simply changing a process.
Can you work with our current ERP or CRM?
Yes: we connect your ERP or CRM with what we build and with the rest of your systems. What we don’t do is implement or configure third-party ERPs: we only implement software that we build ourselves.
How much does a project cost?
The operations audit starts at €2,500 and training at €1,500 per person. Software, automation and agents are quoted after the audit. As an indicative reference: automating a process, between €2,500 and €7,500; an enterprise AI agent, between €5,000 and €15,000; an internal system or application, between €10,000 and €30,000; a custom ERP or platform, from €30,000. Before understanding your case, any other figure would be a lie.
What does the diagnosis include?
The operations audit: operating map, problems detected, estimated cost, opportunities, prioritisation, a 90-day roadmap and an ROI estimate with your own data. It takes five working days from the moment we receive the information, and the report is yours.
Who will own the code?
The code we write for you is yours: no per-user licence and, if one day you continue with another team, you take the system we built, with its documentation and your data. Third-party components (libraries, services, licences) keep their own licence, and the contract sets it out.
How do you protect confidential information?
The first conversation is held with no documents or internal data. If there is a fit, we sign the NDA before you show us anything about your company.
What happens if the project is not viable?
Normally you find out beforehand: if in the 20-minute conversation we don’t see a fit, we tell you and charge nothing. If you have already hired the audit and it concludes that the project is not viable, the audit is still charged, because the analysis is done and the report is yours; we tell you in writing.
How much of my team’s time do you need?
During the audit, roughly one day of dedication for each department involved, with whoever knows how the process is done today. If we then build, we need someone from your company in charge and the system’s output reviewed every day during the first weeks.
How long do you take?
The operations audit takes five working days from the moment we receive the information. A system that affects the whole operation takes longer: the first operational module arrives between 8 and 14 weeks after signing, and we tell you the scope before we start.
What happens after the first conversation?
If there is a fit, we sign the NDA before you show us anything and the operations audit begins. When we deliver the report, you decide, with no commitment. You can start with a single process: you don’t need to develop a complete piece of software.
