The best way to sell real-estate projects.

Landii is software for developers and homebuilders in Colombia who sell off-plan real-estate projects: apartments, houses or lots. It brings together the WhatsApp CRM, OTP signatures, the payment plan, collections, construction updates, 3D design and the buyer and investor portals, from the first message to the deed.

Each account is classified from A to D by days overdue: current, 1 to 30, 31 to 90 and more than 90. Landii sends reminders over WhatsApp within legal hours, issues an automatic receipt for every payment and reconciles the trust or bank statement against each buyer's payment plan.

Yes. A purchase promise only has to be in writing (article 89 of Law 153 of 1887) and a reliable electronic signature has functional equivalence under Law 527 of 1999 and Decree 2364 of 2012. The promise is issued with your company's template, and Landii stores the verified OTP code, the IP, the server time and the document's SHA-256 fingerprint as evidence, with a QR to validate it.

Buyers enter My purchase with their ID and a link sent by email or WhatsApp, with no password: they see their payment plan, receipts, signed documents and construction progress. Investors enter the partner portal read-only: sales by status, collections, receivables and periodic reports, without buyers' names.

When a unit is reserved it gets its plan: down payment, monthly instalments and the balance at the deed. The buyer sees each instalment with its date and status; “Pay” opens the developer's payment link and “I paid” sends the receipt. Once reconciled, the receipt is issued and collections update on their own.

No. The buyer pays the developer or its trust through whatever channel you choose, and Landii records the payment plan, the instalments and the receipts so you can reconcile them. Taking third-party money without authorisation carries criminal penalties in Colombia (Decree 1981 of 1988).

You connect your number through the official WhatsApp API. Every lead lands in the CRM with the unit they were looking at, the AI agent answers with the project's real data and your team picks up the same thread. Your credentials never pass through Landii and the number stays yours.

From the project's units and terrain. Licensed satellite imagery is enough to publish; if the developer already has a drone survey, the project looks like an aerial photo of handover day. An apartment project with no land uses unit types with floor plans and needs no terrain viewer. 3D is included in the monthly fee.

Per published project, not per user: $ 400.000 a month with your whole team included. That price includes the project's 3D design; connecting your WhatsApp number is $ 40.000 a month extra. Paying yearly is 30 % less, and with two or more projects the discount applies to the whole account (10 %, 15 % and 20 %). 15 days of trial with no credit card; during the trial the 3D map is not generated, it is activated with the plan. AI credits start at $ 100.000.

Yes, with the spreadsheet template for units, clients and historical sales. A closed sale never goes back on the market because of an outdated file, and you can export your inventory whenever you want.

The launch page, about ten minutes: you create the project, load the units and publish. The 3D map is processed in a queue with whatever you uploaded —brochure, renders, plans, the surveyor's .kml— and we let you know when it's ready.
