ZEUS Core: an energy offer in minutes.

A tailored energy offer used to cost sales reps hours of calculations and paperwork. ZEUS Core brings the whole sale into one system: the rep prices electricity or gas, sends a PDF offer, the customer signs electronically and commissions are calculated automatically. A custom project for Pražská energie became a product of its own.

From a custom system to a product of its own

Pražská energie a poradenství supplies electricity and gas to businesses and households and helps them save. A tailored energy offer is complicated: distribution tariffs, peak and off-peak prices, regulated charges, taxes. The contract follows right after. Without a system that means hours of work, and every mistake costs money. In July 2025 we started building a system to take that work over.

The rep enters consumption and tariff, AI helps pre-fill the calculation and the system works out the price with every regulated component. The PDF offer is ready in a few minutes. The customer signs the contract electronically, with no printing or scanning. Commissions for reps and partners are calculated automatically from the rate card, and the whole deal is visible in the CRM.

In 2026 we added a customer portal and a community energy module, which handles electricity sharing between members of an energy community, billing included. The system became the ZEUS Core product, now developed by a separate company, Zeuscore s.r.o., with Marqio as its technical partner.

Challenge

A tailored energy offer means working out distribution tariffs, rates, regulated charges and VAT, then preparing a contract straight away. Without a system it takes hours and mistakes are expensive. Sales reps end up spending much of the day on admin instead of selling.

Solution

An electricity and gas calculator with every regulated component, a PDF offer in one click, e-signed contracts, automatic commissions for the whole sales network, a CRM with a deal overview and a customer portal. Everything works from the same data, so nothing gets retyped.

Result

Offers and contracts take minutes instead of hours. Reps retype nothing: the calculation becomes the offer, the offer becomes the contract and the contract drives the commission. Live electricity market prices load every hour, and community energy, billing included, is in live use.
