Overview

The goal was to reduce the rental process to just a few minutes: choose a unit on an interactive map → sign the agreement online → process payment and issue the invoice → activate access automatically. We delivered the full functional scope, operational and financial analytics, and a repeatable white-label implementation model.

Problem

The operator was using several disconnected tools. There was no central control panel, the risk of manual errors was high, online conversion was low, and handling the storage booking process manually was costly.

Solution

We designed a modular architecture consisting of a dashboard, booking widget, and mobile app. The flow includes unit selection from an interactive map, dynamic pricing and insurance, online payments via Stripe/BLIK/Przelewy24, online agreement generation in SignFlow, cloud document storage, webhooks, and automated email flows. We also added an IoT integration for gate opening and access control.

Business impact

↑32% increase in online booking conversion, ↓68% reduction in office handling time, and fewer chargebacks thanks to a clearer payment path and refund policy. KPI visibility in the dashboard and reports improved significantly.

FAQ

Is it possible to implement only the Self Storage facility management system without the booking module?

Yes. The facility administrator can manually add reservations, and we can also optionally generate agreements online or settle storage reservation payments.

Does the system support different rental price lists and add-ons?

Yes — it is possible to create multiple price lists for different storage categories, with dynamic prices and discounts.

Can we implement only the widget — the online booking module?

Yes — the modules are independent. We can start with the booking module and then migrate additional processes later.

How does payment settlement work?

The payment provider supports cards, online transfers, BLIK, and recurring payments. Our system authorizes payments and issues sales documents such as invoices and accounting documents, for example for deposits.
