Sello runs the lettings operation so you can grow without hiring.

I built Sello because I kept seeing the same thing: agencies losing lets to response time and paperwork, not to price or to stock. The enquiry that came in on a Sunday. The reference nobody chased. The room that had been empty for three weeks before anyone noticed.

Most of them had no real system at all. A spreadsheet, a WhatsApp group, a portal login and someone's memory. The advice was always to go and buy a CRM first, which meant paying for a filing cabinet and still doing all the work by hand.

So Sello is both halves. The CRM is there — properties and rooms, landlords and tenants, applicants, viewings, tenancies, repairs — and the operation runs on top of it, so the record keeps itself current instead of waiting for someone to update it. If you already have a CRM you keep it and we extend it instead. Either way the data is yours and it exports whenever you ask. I would rather be easy to leave and worth keeping.
