See it in the demoWhat makes Garentiz different
Three landmarks you will find everywhere in the app.
Every document is evidence
Receipts, letters, messages received: everything is sealed in the time-stamped register and can be checked by a judge, an insurer or your tenant.
Is your file in order?
For each property, the documents that matter if a dispute arises: registered lease, inventory, EPC, insurance, deposit…
And everything else, in one place
Tap a feature to see what it really does.
Rent and bankStatements matched, reminders, receipts.
Due dates created every month, CODA or CSV statements from your bank matched to rent, a friendly reminder, a formal reminder then a formal notice on the timescales you set, receipts sent automatically. Payment notices with a transfer QR code, and SEPA direct debit through a file for your bank.
IndexationHealth index, regional rules, letter.
Health index taken from Statbel, calculation on the lease anniversary, checks of your region's rules (lease registration, EPC (energy performance certificate), Flemish and Brussels corrections based on energy performance) and a letter ready to send.
InventoriesRoom by room, photos, signed on site.
Room by room, with photos, even offline. The content is locked, then signed on the spot, remotely by link and code (e-mail or text message), by QR code or on paper. Its fingerprint goes into the register.
End of lease and depositNotice, move-out, deposit settlement.
Notices and notice periods tracked, move-out inventory, rental deposit settlement and release letter. A claim? A guided file, ready for your insurer.
LettingListing, viewings, applications.
Listing, viewings by time slot, applications compared side by side, then the chosen applicant goes straight to the lease.
Requests and tradespeopleQR code in the property, no account.
A QR code in the property: the tenant reports without an account, the tradesperson gets the job sheet by link and offers time slots, and a round groups several properties in one visit.
Finances and returnsCash flow, yield, budget.
Expenses per property, loans, twelve-month cash flow, returns, a budget forecast as a range, reports and an export for your accountant.
Bank fileYour figures as a PDF for the bank.

Documents and e-mailsFiled by property, with their due dates.
EPC, insurance and leases filed per property, with their expiry dates. Connect your mailbox (IMAP): e-mails are attached to the right property.
Written lease and registrationCompliant with your Region, signed online.
The lease drawn up in line with your Region's rules, in the language you choose, with its annexes (EPC, charges, inventory), checked before signing, signed by code by every party, then guided through registration (MyRent, IRISrent). An existing lease can be uploaded as a PDF.
Charges and statementAdvances, meters, yearly statement.
Provision or flat rate per lease, meter readings, allocation keys (thousandths, floor area, meter, equal shares) and a yearly statement as a PDF with the supporting documents, sent to the tenant with the new provision.
Company, joint ownership, teamEach property under the right entity.
Each property belongs to its landlord entity (you, your company, a joint ownership) and each document goes out in its name, with the required legal details. In a company, everyone has a role with Pro: manager, accountant, assistant.

Alone, as a couple or with your advisers
The portfolio stays yours: you decide who sees what and who can act.
Your accountant, your property manager
Give them read-only access or chosen rights, and withdraw it whenever you like. Reading is unlimited and free.
Delegations
Entrust one property or the whole portfolio to an accountant, a manager, a notary or an agent, with the rights you tick: rent, indexation, inventories, requests, letting. Read-only access is free; an acting delegation requires Pro (or the delegated property's level). Access can be withdrawn at any time.
As a couple, a company or joint owners
Each property belongs to the right entity and each document goes out in its name; joint owners each see their share.
Partners and joint ownership
A spouse, a brother, a partner in your company becomes co-owner of the same account (people who act: 1 on Free, 2 on Essential, 5 on Pro; unlimited read-only). In joint ownership, each owner sees their share of rent, expenses and loans.

all licence rules
Free during the launch phase. Then one licence per let unit (flat, house, studio, shop), per year, VAT included. The home you live in, an empty unit or one under works, a cellar or an attic need none; a flat and its garage let under the same lease count as one licence, and a garage let separately follows the level of the property it is in.
Each unit has its own level: Essential on your flats, Free on the house you let to a relative. Within one property, every let unit must be covered; Pro is taken for the whole let portfolio. A licence can move to another unit once a year.
Batch discount: -5% from 5 licences, -10% from 10, -15% from 20. Batch paid upfront: -20% for three years, -30% for five years, and the price stays locked for the whole batch; the discounts multiply. Price on quotation from 50 units. Companies can display prices excluding VAT (reverse charge for EU businesses outside Belgium). Payment by Stripe, invoiced by Nayaro SRL, Belgium.

Your questions
Does it replace my agency?
Garentiz does the day-to-day work of rental management: tracking rent, sending reminders, indexing, documenting, re-letting a property. It does not visit properties for you or represent you in court. If you want help, you can delegate a property to a manager or to your accountant.
Do my tenants need to sign up?
No. To report a request, they scan the property's QR code, without an account. They sign the inventory on the spot, by link and a code received by e-mail or text message, or by scanning a QR code. If they wish, a free tenant area gives them their receipts, their documents and the follow-up of their requests.
What happens when the trial ends?
During the launch phase, everything is free, all features included. When it ends, existing accounts keep another 60 days of trial; an account opened afterwards gets a 90-day full trial. You are notified by e-mail, with a summary of what Garentiz did for you. After that, the Free level keeps all your units, with no limit and no end date: nothing is locked or deleted. Only the automations (monthly receipts, payment notices, reminders, applied indexation, inventories…) require a licence, unit by unit.
Why a price per let unit?
Because it is what you let: you pay nothing for the home you live in, an empty unit or one under works, or a cellar, and the price follows your portfolio with no tiers or surprises. With Essential, one unit costs €72 per year, i.e. €6 per month: a single rent recovered thanks to a reminder, or an indexation no longer forgotten, pays for several years. A flat and its garage let under the same lease count as one licence.
Can I mix levels?
Yes. Each unit has its own level: Essential on your flats, Free on the house you let to a relative. Within one property, every let unit must be covered for the property to reach that level. Pro is taken for the whole let portfolio, because its features (team, e-mails, accounting export, assistant) apply to the whole account; delegating a single property to a manager follows that property's licence. If you sell a unit or a lease ends, the licence can move to another unit once a year; it keeps its end date.
Can I pay before the launch phase ends?
Yes, that is the pre-sale: a three- or five-year batch paid during the launch phase only starts at the end of your trial that follows it, at the opening price (€60 per unit per year with Essential instead of €72), plus -20% or -30%, and that price is locked for its whole term. You pay nothing twice: everything stays free until then.
Can I give access to my accountant, a relative or a manager?
Yes. Read-only access is unlimited and free at every level. The people who act on the account (you included) are 1 on Free, 2 on Essential (a couple, for example) and 5 on Pro, with roles (manager, accountant, assistant) and the log of who did what.
How does payment work?
You buy a batch of licences on the Licences and invoices page, for one, three or five years (three or five years in the pre-sale during the launch phase), and pay on Stripe's secure page. Garentiz never receives or stores your card number. Invoices, issued by Nayaro SRL, remain available in your account.
Can I stop whenever I want?
A one-year batch renews every year; you can cancel it at any time on the Licences and invoices page, effective at the end of the paid year, or reduce the number of licences of the next renewal. After a renewal, if you are a consumer, you may end it at any time (at most two months' notice) by writing to support: the unexpired part is refunded pro rata. Three- and five-year batches are paid upfront and do not renew. From My data, you export all your data and documents, and can delete your account (30 days to change your mind).
Where is my data?
The platform and its database are hosted in the European Union, with OVH in France. Some providers, used only for their service (payment by Stripe, sign-in and notifications by Google or Apple, the Anthropic assistant if enabled), belong to groups based outside the Union: the privacy policy lists them, with what they receive and the safeguards for transfers. Identity documents and secrets are encrypted, connections too, the database is backed up every day and each account is strictly isolated. Your documents remain yours.
Is my account well protected?
You can turn on two-factor authentication (a six-digit code from an app, with backup codes) or sign in with Google or Apple. Every action on your properties is written to the timestamped register, whose chain is checked every day.
