Hotel software for small guesthouses and B&Bs

In a guesthouse the owner usually does everything: rooms, breakfast, accounting and guest messaging on the side. No round-the-clock front desk and no big software budget. zimrly brings this work together in one complete PMS, without the price and bulk of enterprise systems.

Where guesthouses get stuck every day

No front desk around the clock — late arrivals mean key stress.

Self-check-in with a Nuki or Salto lock: the door code goes out automatically via WhatsApp, the guest lets themselves in, you don't have to be there.

The owner does the accounting personally, in the evening after breakfast service.

The invoicing module creates VAT-compliant invoices automatically and pushes them to easybill, lexoffice, sevDesk or QuickBooks. No more typing.

The same guest questions every day: arrival, parking, Wi-Fi, breakfast times.

The WhatsApp inbox with an AI assistant answers standard questions automatically and only pings you when it really matters.

A helper for breakfast and cleaning — logging hours for the tax advisor is a chore.

The time-tracking export delivers hours as a DATEV, LODAS or Excel file straight into payroll. Included in the invoicing module.

No full PMS — a hotel system isn't worth the price for just a few rooms.

zimrly costs €99 net per month for up to 10 rooms; each additional unit is €8. All features are included.
