Why SpaceStacker

What changes once customers see their ideal unit size.

Rentals and move-ins

Website performance

Team and brand

More self-service rentals

Not knowing what size to book is what stops customers from renting on their own. Seeing the recommended unit in 3D, filled with their own items, removes that doubt.

Higher website conversions

Customers get automated sizing help without leaving your booking flow, so more rentals close online with less reliance on phone support.

Sizing expertise without the training

Using the Planner during calls, your first-week hire and your ten-year manager give the same size recommendation for the same list of items.

Faster rental decisions

SpaceStacker settles the size question right there on your page, so the hardest part of renting online becomes the easiest.

More online engagement

Visitors who meet the Planner play with it instead of skimming past, then carry on into your booking flow. That is engagement a static size guide never produces.

Lower customer service costs

Your team spends less time on size inquiries and unit transfers. That leaves more time for follow-ups, collections and more.

Fewer unit transfers

Customers make better size choices when reserving online, so fewer need a unit transfer on move-in day.

Promotion of all unit types

Lockers, odd sizes and parking spaces get recommended whenever they genuinely fit, because SpaceStacker works from your real inventory, not a generic size list.

Brand differentiation

A unique experience, tailored to your brand and offering, that reinforces your image as an industry leader.

  • Parking units

    Have parking units? Customers select their vehicle to find the spot that fits it best.

  • Smart pop-up button

    Sizing help on every page, one click away. Once customers click through to continue booking, the pop-up displays the size they were recommended.

    Instant recommendation from one click on a preset, and customers can then add or remove items. You can personalize the presets: add, edit, or remove them anytime.

  • Stacking customization

Frequently asked questions

  • How does SpaceStacker go on my website?

    In one or several of three ways: a 3D storage planner embedded on a page, typically your size guide page; a floating smart popup button that opens the planner from any page, or from a button of your own; and 3D thumbnails on your unit size cards, where one click opens the full 3D view.

  • How long until it is live?

    Our side of the work takes about a day. From there it moves at whatever pace suits you and your web team. We handle the setup and walk through it with you before anything goes live, and on your side it is a copy and paste, no technical skill needed.

  • Does it fit my current booking flow?

    Yes. SpaceStacker guides customers to the right unit, then hands them off to the way you already take reservations. If you want it connected to your live unit availability, there are several ways to do that and we will work through them with you.

  • Who maintains SpaceStacker on my website?

    We do. Improvements and new features reach your website automatically, with nothing to reinstall.

  • Does it slow down my website?

    No. SpaceStacker only loads when a visitor scrolls to it, so your page loads at full speed and tools like Google PageSpeed never wait for it. The 3D visualization also adapts its quality to each visitor’s device and connection, the way YouTube adjusts video resolution, so every customer gets a fast, smooth experience.

  • Who gets the customer data?

    You do. Every interaction with SpaceStacker is tracked and made available to you, in your SpaceStacker dashboard and as events in your own Google Analytics. If you use SpaceStacker’s lead forms, the leads land in that same dashboard, with a daily list sent to you.

  • What does it cost?

    One subscription, priced on the number of facilities you operate. It covers setup, ongoing updates, and full access to your data.

If you made it this far, we should talk.

Thirty minutes. A live walkthrough on your actual website.
