The next
generation
of SEMA.

SEMA ONE brings the proven ERP platform fully into the browser — noticeably faster, with the complete feature set. And with what was missing until now: automated workflows, freely designed printouts, digital signatures and analytics right inside the system.

Set it up once.
Then it runs.

SEMA ONE handles recurring business processes on its own — from the trigger to the sent document. One real-world flow, step by step:

Example Invoicing from a completed order
  1. Trigger
    Order is set to “Completed”

    The technician closes the order on a tablet. Nothing else is done by hand — the flow takes over from here.

  2. 1
    Check completeness

    SEMA ONE checks line items, quantities, prices and approvals. If something is missing, the order goes back for clarification — instead of into a faulty invoice.

  3. 2
    Generate the invoice

    Line items, terms and tax rates are carried over from the order; the invoice number comes from your number range. No retyping, no transfer errors.

  4. 3
    Render the PDF from your report

    The printout is produced from your own report layout — letterhead, logo, footer, payment terms. Always the same appearance, with no reformatting.

  5. 4
    Send and file

    The email goes out with the PDF attached to the stored invoice recipient. The same file is filed automatically in the document archive on the order.

  6. Set the status and follow up

    The order reads “Invoiced”, the invoice “Sent”. If payment does not arrive, the next flow starts by itself: the reminder.

Outgoing email automatic

No manual step
No forgotten document
Always the same layout

Before a flow touches real data.

Every flow can be run automatically on your test system — on test data, as often as you like. If a step fails, you see immediately which one, why, and what consequently did not happen.

  2. Check
  3. Generate invoice
  4. Render PDF
  5. Send

  6. Status

Invoice generated 0,31 s
Render PDF — aborted
Report template “Invoice DIN 5008”: mandatory field tax number is not filled in the layout.
Send — skipped
Set status — skipped
Failed No email sent, no invoice posted.
The flow stops instead of producing nonsense

If a step fails, every following step is skipped. No half-finished invoice goes out, and nothing is posted that would have to be reversed later.

The error has an address

The log names the step, the cause and the affected record — in plain language. No digging through log files, no guesswork in the department.

Your own test protocols

Your flows become repeatable test protocols. After a fix, the same protocol runs again — before every change to the system, not once a customer complains.

Everything runs on your test system with test data. Live operation stays untouched — even when a test is deliberately driven into the wall.
The same toolkit, any number of flows

Pick a trigger, define the steps, done. What works for invoicing works everywhere — including in your own established processes.

If Payment overdue Start dunning run
If Order above threshold Request approval
If Picking completed Create delivery note
If Ticket overdue Trigger escalation
If Service interval reached Schedule appointment
If Quote without response Set a follow-up

You build the documents yourself.
From blocks, not from code.

Header, address block, line items, signature — every printout is assembled from blocks that you arrange and configure. No ticket, no service provider, no waiting.

Arrange instead of program

Place blocks, move them, resize them. What a block shows and how it behaves is configured right next to it — columns, borders, row height, page breaks.

Your corporate design, set up once

Fonts, colours, logo, letterhead and footer live in a template. When the corporate look changes, you change it in one place — not in fourteen documents.

Usable in the flow immediately

The finished report is exactly the one a flow pulls in the step “Render the PDF from your report”. There is no release between changing a layout and the changed printout reaching the customer.

Signed before the technician
is back in the van.

No printing, no filing, no scanning afterwards. The customer signs on the tablet — and the document is finished in that same moment.

Delivery note

Order

Customer signature
Signed on site
14:32 Uhr · M. Berger
Signed directly on the record

A tablet or smartphone is enough — at the customer’s site, at the loading dock or in the workshop. The document is opened where it is created.

Documented immediately

Time, signatory and device are recorded on the document together with the signature — traceably documented instead of loose in a folder.

No media break

The signed PDF is filed directly on the order and is immediately available for billing. The invoicing flow can follow on right away.

Drag fields into rows, columns and values — the analysis takes shape as you watch, as a table and as a chart. Directly on the data in the system, with no second tool.

Drag instead of formulas

One field into “rows”, one into “columns”, one into “values” — done. Different question, different field: the analysis rebuilds itself. No formula language, no macro, no IT ticket.

Number and picture from one source

Table and chart hang off the same analysis. Change the breakdown and both change — there is no second figure that failed to follow.

Without export — but with export

Analysis runs directly on the data in the system, under your permissions — no data extract, no stale copy. And if the figures do need to leave the building, export in every direction is available.

One Platform.
Three access points.

SEMA ONE combines the proven Nuclos backend with a modern web frontend. Existing rich client installations remain fully intact.

What customers ask
us first.

Do I have to switch to SEMA ONE?
No. Your rich client keeps running unchanged, and both clients access the same backend. You can activate SEMA ONE in parallel and move your team department by department — or not at all for now. There is no forced migration.
Are our customizations preserved?
Yes. SEMA ONE builds directly on your existing SEMA installation. Data model, screens, customizations and established processes remain fully intact — nothing is re-implemented and nothing is migrated.
Does anything need to be installed?
No. SEMA ONE runs in the browser — on Windows, macOS, Linux and tablets. There is no local installation and no client updates to roll out. The feature scope is complete; this is not a stripped-down web variant.
How does the transition work?
In three steps: your rich client keeps running, SEMA ONE is activated alongside it, and your teams move over gradually. Both clients work on the same data — there is no cut-off date by which everything must be switched at once.
Can we see SEMA ONE with our own data?
Yes. We set the system up on a copy of your data and show you your familiar processes in the new interface — with no obligation and no effort on your side.
What is new compared to the rich client?
Besides noticeably shorter loading times, above all: automated workflows including automated testing of your own processes, freely designed layouts and printouts, digital signatures on tablet and smartphone, a built-in pivot engine for your own analyses, and an MCP server for AI assistants.
Is SEMA ONE part of the existing maintenance contract?
No. The existing maintenance contract covers the previous SEMA applications only. SEMA ONE was developed from the ground up and is therefore offered as an independent application with its own licence or subscription model and a separate maintenance contract.

Not just faster.
Fundamentally more.

Nine innovations that noticeably change the working day — without breaking what you already use today.

Fully compatible with your installation

SEMA ONE builds directly on your existing SEMA installation. Data model, customizations and established processes remain fully intact.

New interface, zero installation

Thoroughly reworked user experience — clearer structure, faster entry, fewer clicks. All in the browser: with the full feature scope, not a stripped-down web variant.

Full feature scope, no compromise
Freely configurable layouts & reports

Screens, layouts and printouts are modular throughout. Adapt documents, forms and reports precisely to your corporate design and your processes — directly in the system.

Fully modular & configurable
Digital signature

Delivery notes, orders and approvals are signed directly in the system — on tablet or smartphone, on site at the customer. The signature is attached to the record instantly.

Paperless efficiency
Workflows & processes

Model your business processes as end-to-end flows: approvals, status changes, notifications and follow-up actions run on their own — by your rules.

Automation made easy
Chat right on the record

Communication happens where it belongs — on the individual order, ticket or document. That saves the email flood and keeps knowledge central in the system, across departments for every authorized employee.

Knowledge stays in the system
New pivot engine

Analyses are ready in seconds — and you configure them yourself, without a detour through IT. No extra BI tool: the pivot engine is built deep into SEMA ONE — including export in every direction.

No extra app
One system, many workspaces

The workspace can be tailored completely to the use case. Configuration alone turns SEMA ONE into a specialized application — a mobile-first shop-floor data capture, for example.

No new apps — all in one package
MCP server for AI integration

An integrated MCP server makes SEMA ONE ready for modern AI assistants: natural-language questions, lookups and analyses — on your data and within your permissions.

AI-assisted working
Non-binding demo — on your own data

SEMA ONE is most convincing with your own records. We set the system up on a copy of your data and show you your familiar processes in the new interface.
