Kronn ERP for Cleaning
Invoicing software for cleaning companies
Every apartment block and office billed on time each month — and each building-management office gets one email, not twenty.
A cleaning company issues dozens of near-identical documents every month: receipts for apartment blocks, invoices for offices and shops. Kronn ERP issues them automatically, each stamped with the month it covers, through a certified e-invoicing provider with transmission to AADE myDATA. For the buildings a management office assigns you, that office gets one email a month with a single merged PDF — and you see who has paid and who still owes.

Built for your line of work
The industry pack is included in Grow and Scale.
01
Client categories and friendly names
Apartment blocks, offices, apartments, shops — and every client under a name you recognise at a glance, like “Ermou 12 apartment block”, instead of its legal name.
02
Partners: building-management offices
Link each apartment block to the management office that assigned it to you, and run reports per partner.
03
One email a month per partner
Once every monthly document for its buildings is issued, the management office automatically receives one email with a single merged PDF — not one message per building.
04
A monthly document per building
Set the amount and service once for each apartment block or office; the document is drafted or issued automatically every month.
05
Reference month on every document
Every receipt and invoice states the month it covers, so managers and residents know exactly what they are paying for — even when it is issued early the following month.
06
Receipts for blocks, invoices for offices
Apartment blocks are billed with a service receipt, offices and shops with an invoice — the right document follows from the client.

- 02
Issued and transmitted
On issue, each document passes through the provider to myDATA and receives its MARK, a unique payment code and your IBAN.

FAQ
Frequently asked questions
Can I send a management office all of its buildings’ documents together?
Yes. Add the management office as a partner and link the buildings it has assigned to you. Once all their monthly documents are issued, one email goes out automatically with a single PDF containing them all.
How are apartment blocks billed, since they are not businesses?
With a service receipt, which is transmitted to myDATA like any other document. Offices and shops receive a service invoice. Every document shows the reference month and carries a unique payment code and IBAN, so the building manager knows what to pay and where.
What changes for a cleaning company on 1 October 2026?
From 1 October 2026, every invoice to a business must be issued electronically through a certified e-invoicing provider — for a cleaning company, every invoice to offices, shops and companies. Kronn ERP includes the provider in every plan, so there is no second subscription.
How much does it cost?
Kronn ERP starts from €10 a month + VAT, billed yearly. The cleaning features — partners, consolidated emails, recurring documents — are part of the industry pack, included in the Grow (€15 a month) and Scale plans.
