Why Hoteo

Your evenings shouldn't be spent doing the invoicing.

Between maintenance visits to chase, certificates to pass on and invoices that drag, the paperwork piles up. Hoteo keeps track of everything for you — so you can head home earlier with your mind at ease.

Your whole trade, in one place

From the first visit to the payment received.

One single tool to track your sites, schedule jobs, invoice correctly and keep an eye on cash flow.

Customers & sites

One customer, several addresses. Everything stays connected.

Property managers, co-owned buildings, owners and tenants: every boiler is attached to its site, with its full history. You find everything in two clicks, without digging.

  • Manage the different sites of one customer and their occupants.
  • Every boiler linked to its site, its contract and its job history.
  • Enter a VAT number → name, address and legal form filled in from the CBE.

Jobs & scheduling

The whole team's task calendar.

One column per technician, each with their own colour. You follow every job from "planned" to "invoiced", and your technicians see their day's schedule right on their phone.

  • Job tracking: planned → confirmed → completed → invoiced.
  • Drag and drop to reschedule, filters by technician and status.
  • Technicians check their task calendar on mobile, with directions and details.

Invoicing & reminders

  • Automatic Belgian VAT with the regulatory legal mention (FPS Finance).
  • Annual maintenance reminders sent all by themselves — no contract ever forgotten.
  • Payment reminders for overdue invoices: follow up in two clicks, with clear tracking.

Testo certificates

The combustion certificate, without retyping it.

Your Testo measuring instruments send their readings straight into Hoteo. The combustion certificate generates itself and files itself on the boiler's record. No more double entry, nothing ever forgotten.

  • Readings imported automatically from your Testo analysers.
  • Compliant certificate generated and archived on the boiler.
  • Always easy to find, ready to send to the customer or the inspector.

And everything that saves you time

The details that change your days.

Bank reconciliation

Connect your account via Ponto: every transfer matches itself to the right invoice.

Peppol sending

Your invoices go straight onto the Peppol network, compliant with Belgian e-invoicing.

CBE lookup

A VAT number is enough: name, address and legal form fill themselves in from the Belgian register.

Technician app

In the field, every technician sees their day's schedule, opens directions to the address and finds the details of every task.

Recurring invoices

Maintenance contracts and subscriptions invoiced automatically, at the right pace, without thinking about it.

Accounting export

A clean, complete export, ready to hand to your accountant at the end of the quarter.

In the field

The whole day, in your pocket.

Hoteo also runs on mobile. Every technician opens their day, launches directions in Google Maps and finds the details of every job — without calling the office.

  • Their day's schedule, always up to date.
  • GPS directions to the address in one tap.
  • The boiler concerned, tasks and notes right in front of them.

Tradespeople with peace of mind.

I used to do my invoices on Sunday evenings. Now it's sorted on the drive home. The 6% VAT — I don't even think about it anymore.

Frequently asked questions

Everything you need to know.

Yes, completely and with no time limit. No credit card is needed to create your account. You manage customers, sites, scheduling and invoices for free, and you only move to Pro when you need banking, automations, the team features or AI.
Your Testo combustion analysers send their readings to Hoteo. The combustion certificate is generated automatically, compliant, and filed directly on the record of the boiler concerned. No more double entry, and the document always stays easy to find.
The AI assistant understands your requests in natural language: schedule a job, find a customer or a boiler, draft a payment reminder, prepare an invoice. AI is included in both plans: 10 requests per month on Discovery to try it out, 100 per month on Pro for everyday use.
It's one of our specialities. Hoteo knows the Belgian schemes — 6% renovation, demolition and reconstruction, social housing, co-contractor, intra-Community — and automatically inserts the exact legal mention, in its up-to-date regulatory wording from the FPS Finance.
Your data is hosted in the European Union, encrypted in transit (TLS), and Hoteo is GDPR compliant. Bank connections are read-only, through licensed providers (Ponto). You remain the owner of your data and can export it at any time.
Hoteo is designed and developed by Saubeo, a Belgian IT services company. A team that listens, knows the field, and evolves the tool with the heating engineers who use it every day.
