Modules

From goods receipt to invoice, one record of the goods.

Lucidus follows the physical goods. Each module is a step in their life, and every step writes to the same parcel history.

Inventory

Your inventory, parcel by parcel

One central view of the whole stock. Every parcel carries its weight, price, deal, location, attributes and status, and every operation on the goods starts from here.

Box and unbox, group and ungroup, split and mix parcels without losing their lineage
Valuation and sorting built in, from price-point splits to the cut-off process for bulk goods
Check-in and check-out, check weights with tolerance thresholds and approvals
Label printing, Excel export and saved views per user

Traceability

Parcel genealogy and history

Every split, mix, box and transfer is a node in the parcel's family tree. Parents, children, price points, certificates and registrations stay linked, and the change history is complete and append-only.

Family-tree view from the original registration down to the last remaining stone
Full change history on every parcel, written by the system and never edited
Parents, children, price points, check weights, certificates and registrations on one screen
Provenance follows the goods from goods receipt through every operation

Procurement

Goods receipt and registrations

Register incoming goods against the supplier's documents, receive them by weighing each item, approve in a controlled step and distribute the cost across the resulting parcels according to their value.

Registration items with declared weight, cost and attributes per line
Receive by weighing every underlying item, or approve on the declared values
Cost balancing spreads the registration's cost across its parcels by value after valuation and sorting
Linked to the vendor, the shipment and every parcel created from the registration

All modules in detail

Workstation

Weigh and print without leaving the browser.

A small background agent connects the balance and the label printer on each desk to Lucidus. Weights arrive in the form as they settle on the scale; labels come out of the printer next to it.

Scales over TCP/IP

The Workstation agent reads precision balances that speak the Mettler-Toledo SICS or Sartorius SBI protocol and hands the live weight to the browser. Manual entry remains available as a fallback.

Label printers through the user's queue

Labels are rendered as PDF on the server and spooled by the agent to the printers installed for the signed-in user, at actual size and with the paper settings of that queue. Windows and macOS are supported.

Installed from the app, updates itself

The agent is downloaded from the settings page of Lucidus, installs per user without administrator rights, registers for autostart and checks for updates on its own. Print jobs take seconds, so an update restart goes unnoticed.

Platform

Built for companies that are audited.

Identity, authorization and a complete history are part of the foundation, not features bolted on later.

Secure sign-in with your company accounts

State-of-the-art authentication including multi-factor authentication, integrated with the account management your company already runs, for example Microsoft Entra ID. No separate passwords to manage, and leavers lose access the moment their company account is closed.

Roles and permissions in the application

Who may do what is defined in Lucidus. Roles bundle granular permissions for the activities of the business, from viewing stock to approving check weights or completing invoices, and users hold one or more roles.

Complete change history

Every change to a batch, registration, invoice, sale or master-data record is written to an append-only history with user and timestamp. The genealogy of goods is derived from the same records, so audits start from data rather than from recollection.

Lightweight browser application, mobile ready

Lucidus runs in current browsers on desktop and mobile devices. Views with thousands of parcels, server-side paging and filtering, and saved views per user keep it fast on everyday hardware; only the optional Workstation agent for scales and printers is installed locally.

Modern, cloud-native platform

Built on a current, actively maintained technology stack and operated as a cloud service, with embedded reporting on live data and a data region agreed per customer.

Questions

Common questions, short answers.

Which browsers and devices does Lucidus run on?

Lucidus is a lightweight web application and runs in current versions of Chrome, Edge, Firefox and Safari on Windows and macOS, and on tablets and phones for viewing and quick checks. Daily operations are designed for a desktop with a keyboard and, usually, a scale and a label printer.

Do I need to install anything?

Only if you want to connect a scale or a label printer. The optional Workstation agent is a small background program for Windows and macOS that reads the connected scale and prints labels on the printers of the signed-in user. It installs without administrator rights, is downloaded from inside Lucidus and updates itself.

Can my team use their existing company accounts?

Yes. Lucidus integrates with your company’s account management, for example Microsoft Entra ID, so the accounts, passwords, multi-factor authentication and access policies you already manage apply. Who may do what inside Lucidus is defined by roles and permissions in the application. Other identity providers can be connected on request.

Which scales and printers are supported?

Scales that speak the Mettler-Toledo SICS or the Sartorius SBI protocol over TCP/IP are supported out of the box; that covers most precision balances used in the trade. Labels are rendered as PDF on the server and printed on any printer installed on the workstation, which includes the usual thermal label printers. Other protocols can be added through the agent’s device layer.

Can we import our existing stock?

Yes. The transfer import accepts spreadsheet-style data for groups, boxes and individual weights, validates it against your material types, deals and attributes and creates the batches in bulk. Master data such as deals, companies and attributes can be uploaded in bulk as well. A typical migration starts with the master data, then the open stock, then the live operations.

Can invoices and labels carry our own layout?

Yes. Invoices, labels and other printouts are rendered from HTML templates that belong to your company. Logo, address block, terms, fonts and column layout are part of the template and can be changed without a software release.
