Accounting and invoicing

Custom ERP and CRM Software in Luxembourg: Management, Accounting and Customer Relations
Multiplying spreadsheets, data typed in twice, software that does not talk to each other: when admin slows the business down, an ERP or CRM built around your processes puts everything in one place.
Kolot develops custom management software for businesses in Luxembourg: accounting and invoicing, stock, purchasing, customer relations and dashboards, connected to the tools you already use.
Modules we develop
We build only the modules you need, and evolve them with you:
Stock management
Items, warehouses, movements, inventories and reorder alerts.
CRM and sales
Customer records, communication history, sales pipeline, follow-ups and quotes.
Purchasing and suppliers
Purchase orders, goods receipts and matching with supplier invoices.
Projects and planning
Project, time and resource tracking, with progress-based invoicing.
Dashboards
Revenue, margins, stock and sales activity in real time.
Software adapted to Luxembourg rules
Management software used in Luxembourg has to reflect local obligations. We build them in from the start, together with your accountant:
- Standard chart of accounts (PCN) and exports compatible with your fiduciary’s tools.
- Luxembourg VAT: rates of 17%, 14%, 8% and 3% depending on goods and services, and handling of intra-EU transactions.
- FAIA file: export of the standard audit file that the Registration Duties Administration (AED) may request.
- E-invoicing in the Peppol format, mandatory for public procurement in Luxembourg.
- Data prepared for eCDF, the electronic filing platform for returns.
- GDPR: role-based access, activity logs and hosting in the European Union.
Tax settings are always validated with your accountant.

Custom ERP or off-the-shelf software?
Off-the-shelf software
Odoo, Sage or an online invoicing tool work well for standard processes, with a lower starting cost.
Custom software
Better when your processes are specific, several tools need to be merged, or per-user licences become expensive.
Both together
We can also build a custom module that connects to your existing ERP, instead of replacing everything.
Software connected to your other tools
Your ERP or CRM can feed your online store, mobile app or website. See our custom app development, e-commerce development connected to your stock, or AI integration to automate data entry and document sorting.
