Choose Seido if your number-one pain is the WhatsApp/email/phone scatter and you want to centralise incoming requests.
Choose Smovin if your priority is financial automation of rentals: bank-based rent tracking, indexation, rent receipts and expense statements.
Both automate rental management (bank connection, rent tracking, receipts) and overlap on those tasks. The real difference is the audience: Smovin primarily addresses investors and multi-property owners, Seido addresses agencies.
Smovin at a glance
Smovin is a Belgian software solution founded in 2017, based in La Hulpe, specialised in rental management automation: payment tracking through a bank connection, automatic rent indexation, rent receipts and expense statements. It primarily addresses property investors and multi-property owners, in Belgium and France.
When Smovin is a good choice
- You manage your own portfolio (investor, multi-property owner) and want to automate rent tracking: payments identified through a bank connection, automatic reminders by SMS, email, letter or registered mail.
- You are looking for a tool that keeps indexation rules up to date, region by region.
- Automatic generation of rent receipts, indexations and expense statements is a daily blocker for you.
When Seido is a better fit
- You are an agency: requests come in via WhatsApp, email, phone and SMS, and you lose hours reconstructing who asked what about which unit.
- You want AI triage that categorises incoming requests and suggests the right contractor in under 30 seconds.
- You are looking for dedicated contractor and tenant portals to eliminate manual follow-ups.
