NIZU modules connected to RentOp

RentOp does not keep a second copy of your guests, invoices or tasks. It uses the NIZU modules you already have, so every stay shows up where the rest of your business already looks.

The modules

• Clients every guest and tenant becomes a client with a contact; their stays and leases show on a “Stays & leases” tab of the client.
• Invoices and Payments each stay gets an ordinary invoice, the online payment is recorded on it; leases use a recurring invoice that repeats every month. A payment received another way (cash on arrival, a bank transfer) is recorded with Record a payment and lands on the same invoice.
• Payment methods Stripe and Mollie with the keys already saved in Settings; the RentOp Payments tab shows whether each is ready.
• Tasks a cleaning task is created when a guest checks out, assigned to the property's cleaner and due before the next arrival.
• Leads an enquiry about a long-term property on the website (“Interested? Tell us.”) becomes a lead with a note.
• Email templates booking confirmation, balance reminder, arrival instructions, review request, cancellation and lease welcome, editable per language.
• Notifications new bookings, cancellations, channel clashes and new reviews.
• Dashboard tiles for arrivals today, departures today, guests staying now, occupancy this month and revenue this month.
• Files the property photos and videos, and the website banner photo or video, are stored with your workspace's own files, in your own database and storage.
• AI Reports stays, leases and occupied nights in “All business data”.
• Marvin ask about arrivals, departures and availability; the Marvin chat can also run on your booking website (Settings → Website → Live chat).
• WhatsApp Coexistence guests who accepted WhatsApp receive their messages there too (Settings → Messages → Also send on WhatsApp).
• NIZU Sign optional: rental agreements signed with a full audit trail (Settings → Agreements).
• Agents (MCP) connected AI assistants can read properties, prices and bookings, and book, cancel or close nights with the same calendar as the website.

What happens across the modules when a guest books

A lease across the modules

When you click Activate on a lease, RentOp blocks the property's calendar, creates a recurring invoice in Invoices that repeats every month on the rent due day, and e-mails the tenant with the Lease welcome template. The tenant is a client like any other, so their rent invoices, payments and messages are all on the client's page.
