What Tremol does

Tremol is a Bulgarian technology company group operating through two principal entities, Tremol Ltd and Tremol SMD Ltd, headquartered in Veliko Tarnovo, Bulgaria. The group was founded in 2002, with Tremol SMD established in March 2006 to provide electronics manufacturing services and Tremol Ltd commencing operations in 2009 as the fiscal device commercialization arm. Across both entities the group employs more than 400 people, of whom 250+ work in Tremol SMD's electronics manufacturing operation. The company is privately held by Petar Yordanov Kolev and Ralitsa Tremol Koleva.

The group's core business is the design, manufacture, certification, and distribution of fiscal cash registers, fiscal printers, and specialized fiscal devices (including bus and vending machine units), together with the TREMOL POS software family (four variants) and the TREMOL Assistant cloud service for remote device management. Tremol also exposes the proprietary ZFPLAB SDK for third-party developer integration. Through Tremol SMD, the group offers contract electronics manufacturing services (SMT/PCB assembly) to external customers, leveraging IPC-certified production capabilities. Hardware is priced in the €149-€343 range per unit, and software is licensed to end customers and integrators.

Tremol generates revenue via hardware unit sales, POS software licensing, recurring or subscription-style cloud service revenue from TREMOL Assistant, and contract EMS revenue through Tremol SMD. Go-to-market is via a network of 400+ distributors in Bulgaria, direct website sales, and 17 international partner countries. End customers are primarily small and medium-sized businesses across the retail, food and beverage, transport, pharmacy, and vending verticals, with a heavy concentration in Bulgaria and incremental international exposure. In 2025 the company proactively recertified its entire fiscal device portfolio for euro currency compliance in anticipation of Bulgaria's euro adoption, and in December 2024 secured EU RRF funding of BGN 358,740 for a printed circuit board innovation project.

Scale indicators7 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Jabil: Global tier-1 EMS/ODM operating in automotive, industrial, healthcare and aerospace electronics with SMT, AOI and conformal coating capabilities analogous to Tremol SMD. Represents the scale competitor Tremol SMD is benchmarked against in the same EMS verticals.
• Flex (Flextronics): Global EMS provider serving automotive, industrial, medical and aviation electronics - the exact same verticals Tremol SMD targets. A broad incumbent that competes for similar CEM contracts where Tremol SMD's SMT/AOI capabilities overlap, though at significantly greater scale.

Emerging players

• SumUp: Mobile card-reader and POS platform expanding across Europe with low-cost terminals and SaaS pricing. An emerging disruptor that competes for the same Bulgarian SMB checkout segment using simpler, software-centric hardware rather than full NRA-certified fiscal devices.
• myPOS: European all-in-one POS and payment terminal provider expanding in Bulgaria and SEE. Competes at the lower end with integrated payment terminals and software bundles that could pressure Tremol's value-tier cash register sales to small merchants.

Direct peers

• Daisy Technology: Bulgarian developer of fiscal devices, POS software and cash registers also certified for Ordinance H-18 NRA connectivity. Daisy is a direct peer serving the same regulatory-driven Bulgarian merchant base with comparable hardware/software bundles.
• Datecs: Bulgarian manufacturer of fiscal cash registers, fiscal printers and POS terminals with the same NRA/H-18 compliance focus. It is the most direct competitor to Tremol's core fiscal hardware line and competes head-to-head for the same Bulgarian SMB and retail merchants via overlapping distributor networks.
• Eltrade: Bulgarian provider of cash registers, fiscal printers and POS systems targeting retail, hospitality and transportation customers. Competes directly with Tremol in the same Bulgarian fiscal certification category, especially for small and mid-sized merchants.
• Datecs (EMS / POS)] removed - duplicate: placeholder

Regional players

• Iskra EmEco: Slovenian-headquartered manufacturer of metering, automation and related hardware with regional SEE distribution. Comparable to Tremol as a Balkan-region electronic equipment provider with similar compliance-heavy product requirements, though not solely focused on POS.
• Incotex (Efox): Croatia-based manufacturer of fiscal cash registers and printers serving the Adriatic and Balkan region. Direct functional peer in fiscal device certification but operates primarily in Croatia and nearby Western Balkan markets rather than Bulgaria, where Tremol is dominant.
