Invoicing your rentals is chaos?
Manual invoicing, no KSeF integration and lost documents - sound familiar?
Manual data entry
You copy data from the rental agreement onto an invoice. Each invoice takes 10-15 minutes and risks errors in tax IDs or amounts.
No KSeF integration
The e-invoice mandate is approaching fast, yet you're still emailing or printing invoices. You have to log into a separate system.
Invoices lost in paperwork
Clients ask for duplicates while you search through folders. No central archive and no instant PDF access.
Corrections are a nightmare
Error on an invoice sent to KSeF? Manual correction creation, re-submission and number tracking. It doesn't have to be this hard.

Frequently asked questions about invoicing and KSeF
Is KSeF integration mandatory?
The Polish National e-Invoice System (KSeF) becomes mandatory in 2026. Toolero lets you prepare now - you can test submissions in the KSeF test environment with no consequences.
How do I configure KSeF in Toolero?
Go to Settings → KSeF, enter your company tax ID, paste the auth token from the KSeF portal and choose environment (test or production). Setup takes 2 minutes.
What happens when KSeF rejects an invoice?
The system automatically marks the invoice as rejected and shows the error reason. You can fix the data and retry with one click.
Can I issue correction invoices?
Yes. Correction invoices are created from the original invoice, automatically linked to the source document. The correction also goes to KSeF.
Can I use invoicing without KSeF?
Yes. KSeF integration is optional. You can issue VAT invoices, generate PDFs and manage statuses without activating the KSeF module.
Is invoice data secure?
The KSeF auth token is encrypted and stored securely. Communication with KSeF is over HTTPS. Your invoice data never leaves encrypted connections.
