The Client: Project Parking Bulgaria SLLC
Project Parking Bulgaria SLLC is a Sofia-based parking operator and smart-mobility integrator headquartered at Filip Stanislavov 8 in the Bulgarian capital's 1505 postal district. Its Bulgarian limited-liability structure (SLLC) confirms a local operational footprint rather than a subsidiary of a larger Western European integrator, and its name signals a clear market focus on parking.
Project Parking Bulgaria's first order, placed on 29 May 2025, was not just its own first Fleximodo purchase — it was the first Fleximodo smart parking deployment in Bulgaria as a national market, adding Bulgaria to a European footprint that already included Germany, France, Belgium, Italy, Greece, Czech Republic, Slovakia, Hungary, Serbia, Kosovo, Malta, and others. Sofia is a 1.2 million-person capital with growing smart-city investment, EU-structural-fund access for infrastructure modernisation, and a technology services sector that has historically punched above its weight in Eastern Europe. That a Sofia-based operator chose to launch with a sophisticated full-stack pilot — not a basic sensor-only trial — signalled commercial ambition from day one, and the two orders that followed over the next ten weeks confirmed it.
Phase 1 (May 2025): A Reservation-Capable Pilot From Day One
Most first orders Fleximodo receives from a new integrator deploy a handful of sensors without advanced signage or CityPortal capability. Project Parking Bulgaria's opening order was different: it specified two distinct parking guidance signage variants at once, each built for a different purpose.
The first was standard 2-digit Parking Guidance Signage, which displays the number of available spaces — the classic driver-guidance use case. The second was an 8-digit Parking Guidance Signage configured to display license plates for reservations, a non-standard configuration that supports reservation-based parking: a driver who has pre-booked a space sees their own license plate called out on the display on arrival, confirming that the assigned space is being held for them.
Reservation parking is a distinct commercial category from classic occupancy guidance. First-come-first-served smart parking only needs sensors and an aggregated-counter guidance display. Reservation parking additionally needs a booking database, a way to associate bookings with sensors, a way to verify arrival identity, and a way to communicate the specific space assignment to the arriving driver. Project Parking Bulgaria's opening order assembled the entire stack required for this at once:
- IoT Parking Sensor Standard (NB-IoT, flush-mount) for parking occupancy detection at each bay — 1-year warranty, bundled 10-year NB-IoT SIM, reversible flush-mount installation without permanent core-drilling
- Permit Card (Bluetooth, white-labelled) to associate specific vehicles with specific bookings — 1-year warranty, client branding included
- CityPortal (pilot tier) as the backend managing the reservation database, occupancy state, and license-plate dispatch, accessible to Project Parking Bulgaria's team via CityPortal login
- 2-digit Guidance Signage for non-reserving drivers, and 8-digit Guidance Signage for reserving drivers, both NB-IoT-connected, solar-powered outdoor beacons with installation equipment included
- Bronze Card support (5 hours) for first-year onboarding
Commercial contexts where this kind of reservation capability matters include corporate car parks where employees book spaces by shift, hotel parking with VIP guest assignments, hospital parking for scheduled appointments, airport long-term parking, event parking, and commercial lots offering premium reservable tiers alongside standard first-come service. Launching with full reservation capability on a first order suggested Project Parking Bulgaria already had a specific Sofia customer in mind — most likely a commercial operator rather than a municipality, since municipal parking rarely requires per-space reservation enforcement.
Phase 2 (June 2025): From Functional Pilot to Market-Ready, Bulgarian-Branded Product
Just 19 days after the first order, on 17 June 2025, Project Parking Bulgaria came back with a second order — not more sensors, but a compact package that turned the pilot from a functional deployment into a fully localised, client-branded product suitable for customer-facing presentation. Most Fleximodo pilots run 3-6 months before an integrator requests localisation and branding; Project Parking Bulgaria compressed that cycle to under three weeks, a pace that pointed to either thorough requirements-gathering before the first order or a named Bulgarian customer waiting on the branded version before a follow-on commercial conversation could close.
The second order addressed three gaps between "functional" and "market-ready":
UWB upgrade. Standard Bluetooth Permit Cards identify a vehicle within a few metres — adequate for basic permit enforcement, but not for reservation systems that need to know exactly which space is occupied. Project Parking Bulgaria added UWB (Ultra-Wideband) functionality to 25 sensors and 25 Permit Cards, upgrading them from BLE-only to BLE+UWB. UWB adds centimetre-accurate localisation, enabling precise space-level identification, enforcement against piggyback parking (unauthorised vehicles occupying reserved spaces), and reliable identification in high-density settings where multiple Permit Cards sit close together. Because UWB chipset integration happens at manufacturing rather than as a retrofit, the 25-and-25 unit count represented new UWB-capable hardware shipped to Bulgaria to supplement the already-deployed pilot.
Physical and platform branding. Custom laser etching gave the sensor bodies permanent, tamper-resistant branding that survives the hardware's full operational lifetime, while white-labelled stickers put the Permit Cards under Project Parking Bulgaria's own brand rather than generic Fleximodo markings. CityPortal itself was white-labelled to match.
Bulgarian-language localisation. CityPortal's default interface is English, but Bulgarian customers — particularly municipal buyers and general-public drivers — expect a Cyrillic-script interface. Project Parking Bulgaria provided its own translation, and Fleximodo handled the technical integration: importing the translation strings, testing Cyrillic rendering, and verifying layout integrity. That division of labour — native-speaker translation paired with vendor-side technical integration — produced a faster, higher-quality localisation than an outsourced translation service could have, and turned CityPortal login screens, dashboards, and driver-facing text into what reads as a native Bulgarian mobility application rather than an imported one.
Phase 3 (August 2025): An Active Rollout, Not a One-Off Pilot
The third order, dated 4 August 2025 — roughly ten weeks (seventy days) after the first — contained no new sensors, Permit Cards, or software. It was a guidance-signage shipping, packaging, handling, and insurance charge, sent separately from the original consolidated shipment.
A shipping-only order carries no dramatic headline feature, but it is informative in what it confirms: the deployment is still in active delivery. Guidance signage and sensors often have different lead times and commissioning requirements, so shipping signage separately lets an integrator install and commission sensors first, then receive signage once on-site installation requirements are finalised — reducing on-site storage needs and matching the sequencing of the installation plan. For Project Parking Bulgaria, this order is the administrative trace of digital parking signage continuing to flow into the Sofia deployment as field commissioning proceeds.
Read together, the three orders form a textbook multi-phase rollout rhythm: first-order hardware and platform, mid-phase functional and branding expansion, and final-phase logistics. Structuring the relationship as sequential orders rather than one consolidated procurement gave Project Parking Bulgaria cash-flow smoothing and the flexibility to adjust specifications between phases based on field learnings, while giving Fleximodo early, regular visibility into whether the Bulgarian market entry was on track to scale.
Why Project Parking Bulgaria Kept Ordering From Fleximodo
Across three orders in ten weeks, the pattern is consistent: each order built directly on the one before it rather than starting a new evaluation from scratch. The first order proved out a full reservation-capable stack — sensors, Permit Cards, CityPortal, and dual-variant guidance signage — in one deployment. The second order, arriving before any meaningful operational data could realistically have accumulated, showed Project Parking Bulgaria already knew its Bulgarian market required UWB precision, its own branding, and a Bulgarian-language interface — and that Fleximodo could deliver all three within three weeks. The third order showed the relationship had settled into an operational rhythm, with signage logistics flowing on demand rather than requiring a new sales cycle each time. For a company opening a brand-new national market, that combination of technical depth (dual detection sensors, reservation signage, UWB precision) and delivery speed (19-day customisation turnaround) is what turned a single pilot into a repeat-order relationship.

What is automatic temperature compensation? It is a calibration technique built into Fleximodo's magnetometer parking sensors that corrects for magnetic-field drift caused by changes in ambient temperature. Sofia's continental climate swings from hot summers to cold winters, and without compensation those swings could shift a magnetometer's baseline reading enough to trigger false occupancy detection. Fleximodo's sensors apply this compensation automatically, which is how the dual detection technology — magnetometer combined with radar — maintains 99.96% parking occupancy detection accuracy year-round regardless of season.

Frequently Asked Questions
What makes this deployment a Bulgarian market first? Project Parking Bulgaria's May 2025 order was the first Fleximodo smart parking deployment in Bulgaria as a national market, adding Bulgaria to Fleximodo's European footprint alongside Germany, France, Belgium, Italy, Greece, Czech Republic, Slovakia, Hungary, Serbia, Kosovo, Malta, and others. Sofia's 1.2 million population, EU-structural-fund access for infrastructure, and growing technology services sector make Bulgaria a strategic market for Central-Eastern European expansion.
Why deploy 2-digit and 8-digit signage together? The two Guidance Signage variants serve different purposes within a single parking guidance system. 2-digit signage shows the number of available spaces for classic driver guidance; 8-digit signage displays license plates of arriving drivers who have pre-booked spaces, confirming the reservation and identifying the assigned location. Deploying both together lets one system serve first-come-first-served and reservation-based customers simultaneously.
Why are sensors and signage specified with 10-year NB-IoT SIMs? Bundling a 10-year NB-IoT SIM with each hardware unit eliminates recurring connectivity administration for the entire operational lifetime of the deployment — no further SIM management, billing, or renewal cycles across the next decade.
Why did Project Parking Bulgaria upgrade to UWB just 19 days after its first order? UWB (Ultra-Wideband) adds centimetre-accurate localisation to sensors and Permit Cards, enabling reservation-based parking with exact space assignment, enforcement against piggyback parking, and reliable identification in high-density settings. A 19-day turnaround — well before meaningful pilot data could have accumulated — indicates the requirement was specified from day one, either by Project Parking Bulgaria's own planning or by a named end-customer waiting for the enhanced functionality.
Why does Bulgarian-language localisation matter for CityPortal? Bulgarian customers, particularly municipal buyers and general-public drivers, expect software in Bulgarian with Cyrillic script. A generic English-language interface signals the technology is foreign and can reduce trust. White-labelling CityPortal and adding full Bulgarian translation turns it into what reads as a native Bulgarian mobility application, including CityPortal login screens and driver-facing text.
Why did the client provide the Bulgarian translation rather than Fleximodo? Native speakers produce better translations than generic translation services, particularly for technical and user-interface content where domain expertise and cultural nuance both matter. Project Parking Bulgaria supplied the Bulgarian text; Fleximodo handled the technical integration — importing translation strings, testing Cyrillic rendering, and verifying layout integrity — producing a faster and higher-quality result than outsourcing.
Why does guidance signage sometimes ship separately from sensors, in its own order? Guidance signage and sensors often have different lead times, commissioning requirements, and packaging needs. Shipping signage separately lets an integrator install and commission sensors first, then receive signage once site-installation requirements are finalised — reducing on-site storage needs and matching the rollout's installation sequencing.
What is automatic temperature compensation, and why does it matter for outdoor sensors in Sofia? Automatic temperature compensation is a calibration technique in Fleximodo's magnetometer parking sensors that corrects for magnetic-field drift caused by ambient temperature changes. Sofia's continental climate swings from hot summers to cold winters, and without compensation those swings could shift a magnetometer's baseline reading enough to cause false occupancy detection. Fleximodo's sensors apply this compensation automatically, which is how they maintain 99.96% detection accuracy year-round.
Why did Project Parking Bulgaria keep ordering from Fleximodo? Each of the three orders built directly on the one before it. The first order proved out a full reservation-capable stack in a single deployment; the second, arriving only 19 days later, showed Project Parking Bulgaria already knew its market required UWB precision, its own branding, and Bulgarian-language software — and that Fleximodo could deliver all three quickly; the third showed the relationship had settled into a working operational rhythm, with signage logistics flowing on demand. That combination of technical depth and delivery speed is what turned a single Sofia pilot into a repeat-order relationship across Bulgaria's newest smart parking market entry.
