HotelOne connects sales, purchasing, stock, accounting and management information, and builds on the systems the hotel already uses.
Sync takes care of sales. WMS Effect is the cloud warehouse that automatically reads goods received notes and invoices. Documents AI keeps the archive in order. Integrations sends sales and purchase invoices to accounting, SAF-T ready. BI shows every day how yesterday went - on your phone or computer. PMS, POS and accounting stay the same.


We start from these questions, because every automation should have a specific operational problem behind it.
Sync sends rates and availability to every channel, accepts reservations automatically and lets you manage sales from one place.
Sync · one place for salesA sale starts in the PMS or POS, a purchase in WMS Effect. Integrations sends both sales and purchase invoices to accounting automatically - SAF-T ready.
One entry · one flowWhen data moves automatically, the team doesn't retype it between systems. That saves time and operating costs and cuts errors where they cost the most.
Automation with controlRevenue, purchases, costs, occupancy and variances are available every day on phone or computer - for staff, the management team and the owner.
BI · timely informationHotelOne brings sales and costs into one picture. Instead of several versions of Excel you get one answer and can find the cause.
One version of the dataThe connections don't depend on a single vendor. You can replace a specific component without rebuilding the whole setup from scratch.
The integrations stayFor one hotel that's rates and reservations across dozens of channels. For another it's purchasing, stock, or the report that arrives too late. We solve the specific problem first and widen the scope when it makes sense.
We pick the process that takes the most time or costs the most money. From the start we agree how we'll measure the benefit.
PMS, POS, stock and accounting stay. The team keeps working with the tools it knows.
We check how much manual work has gone, how much earlier information arrives and whether the change shows in the financial result.
The six products cover different moments in the hotel's work and exchange data with each other.
Sync sends rates and availability to 141 channels, accepts reservations automatically and passes them to the PMS. OTAs, wholesalers, DMCs, GDS, tour operators and direct sales are managed from one interface.
SyncThe hotel keeps using Clock, Creato, Opera or another PMS. The POS records sales in F&B, SPA, GOLF and the other outlets.
Your PMS · POSThe established specialised warehouse software for hotels now runs in the cloud. It's used by over 400 hotels and automatically reads goods received notes and invoices.
WMS EffectSales and purchase invoices are sent to accounting automatically, with the data prepared for SAF-T. Room keys, NSSI reports and BAVEL are also handled with no manual retyping.
IntegrationsOn phone or computer the owner sees the P&L, the revenue manager pickup, pace and occupancy, and the F&B manager the margin by outlet. The information is ready every day, before the meetings start.
BI · FlagshipIn buildings with separate owners, OMS tracks each apartment, allocates revenue and costs and prepares a clear statement for the owner.
OMSSoftware is only worth something if it makes the working day lighter and decisions better.
Reservations come in automatically, rates and availability go out to the channels, and purchases and documents aren't retyped between systems.
Less routine and fewer errorsYesterday's sales, purchases, costs, occupancy and variances are ready every morning - on phone or computer.
Faster decisionsOne picture of revenue and costs, with the option to go from the overall result down to a specific outlet, channel or process.
Clear cost controlIt's no accident that hotels build their technology stack from different systems. That way they choose what suits their type of property, processes and team best. Every All-in-One platform comes with its own general model of how a hotel "should" work. That model struggles to cover each property's specific needs, and the hotel starts adapting to the software.
Manages sales from one place: sends rates and availability to every channel, accepts reservations automatically and passes them to the PMS with no manual transfer.
The cloud warehouse used by over 400 hotels. It automatically reads goods received notes and invoices, tracks stock and cost, and supports mobile stock counts.
Every morning it shows on phone or computer how yesterday went. P&L, sales, purchases, costs, pickup, pace and variances are available while you can still act.
Sends sales and purchase invoices to 40+ accounting systems, SAF-T ready, and connects the hotel with door locks, METRO, NSSI, BAVEL, BI and other external systems.
Collects invoices, receipts, notes and contracts. It indexes them with AI and finds a document even by information from a single line.
For hotel buildings with separate owners. It tracks occupancy by apartment, allocates revenue and costs and prepares the reports.
A good demo isn't enough. You need working connections, knowledge of local requirements and a team that understands what happens after the button is pressed.
For more than 20 years we've built solutions in the real environment of Bulgarian hotels - from the front desk to the warehouse and accounting.
USALI, hotel recipes, cost of sales, BAVEL and NSSI are part of the products' core logic, not customisation after rollout.
It reads documents, indexes lines, answers questions in Bulgarian and points attention to variances. We use it where it saves time.
HotelOne has 60+ working integrations. If you change your PMS or accounting software, the rest of the setup doesn't have to be rebuilt from scratch.
The platform runs on AWS infrastructure located in the European Union and uses two-factor verification. NRA, NSSI and SAF-T requirements are part of the solutions.
Sync works with OTA, GDS, wholesaler and DMC networks, as well as groups such as DER Touristik. Support is local, distribution is global.
Behind many of the products is the HOT team, led by Daniel Asenov. With more than 20 years in the industry, Daniel is one of the leading names in hotel integrations in Bulgaria. His solutions handle the communication between PMS, stock and accounting in many hotels across the country. Now that expertise is becoming part of HotelOne.
