Rental management doesn't happen in isolation. When someone checks out equipment, your logistics team needs to know. When a rental goes overdue, maybe your accounting system should flag the deposit. When a new renter signs up, perhaps your CRM should get updated.

Most rental tools treat these connections as "nice-to-have" or require expensive enterprise plans to access. In Stockaj, webhooks are available on the Professional plan — and they're powerful enough to replace custom middleware.

This guide covers what webhooks are, how to set them up, and five real automations that teams are using to eliminate manual handoffs.

Tool libraries are having a moment. Across Europe and North America, community organizations, municipalities, and NGOs are building structured lending programs for everything from power drills to camping gear, furniture to farming equipment.

The idea is beautifully simple: instead of 50 households each buying a circular saw they'll use twice a year, one organization owns 3 and lends them out. Less waste, lower cost, stronger community.

The execution, however, is where things get complicated. Because a tool library isn't a library of books. A wrench doesn't have an ISBN. A donated sofa doesn't come with a catalog entry. And when items circulate between dozens of people across months, keeping track of what's out, what's back, and what's broken becomes a full-time job.

This guide is for the people doing that job — often volunteers — who need a practical system that works without an IT department.

Picture this: you manage a shared workshop, a festival equipment pool, or a community tool library. People come in, grab what they need, and leave. The question is — do you know what left, who took it, and when it's coming back?

Most organizations solve this with a clipboard, a spreadsheet, or a dedicated staff member sitting behind a desk. All three solutions fail at scale: the clipboard gets lost, the spreadsheet gets stale, and the staff member costs money and gets bored.

There's a better approach: a self-service kiosk. A screen at the entrance (or exit) where people scan items, identify themselves, and check things out or return them — no human intermediary required.

Here's how to set one up with Stockaj Kiosk in about 15 minutes.

If you've searched for "inventory management software" recently, you've almost certainly come across Sortly. It's well-known, visually clean, and does a solid job at what it's designed for: tracking what you own and where it is.

But if your organization doesn't just own things — if you lend, rent, or circulate items — you've probably noticed that Sortly starts falling short quickly. Because Sortly is an inventory tracker. It was never designed to manage the complex lifecycle of rentals.

This is where the tools diverge, and it's worth understanding the differences before committing your team to either one.

Every rental business starts the same way: a handful of items, a spreadsheet, and the belief that "we'll upgrade the system when we grow."

Then you grow. And the spreadsheet doesn't.

Suddenly you're spending hours reconciling stock, items vanish between events, and nobody can tell you whether that projector is on-site, in the warehouse, or on its third unreturned rental. Sound familiar?

Here are the seven most common inventory tracking mistakes I've seen across hundreds of rental operations — from festival logistics teams to NGO tool libraries — and what to do about each one.

You've signed up for Stockaj. Now what?

This guide walks you through the entire flow — from creating your first item to completing your first rental — in under 5 minutes. No configuration needed, no complex setup. Just the essentials to get you productive immediately.

If you've ever organized a festival or a multi-day event, you know the drill: walkie-talkies that disappear, barriers that end up at the wrong venue, and a spreadsheet that stopped being accurate two days before the event started.

Equipment management at events is a logistics nightmare — not because the individual tasks are hard, but because everything happens at once, across multiple locations, with volunteers who rotate every few hours.

When I started building Stockaj, the first real decision wasn't about features, tech stack, or pricing. It was about where the data would live.

That might sound trivial. Most SaaS founders pick AWS us-east-1, call it a day, and move on to building features. But I'm based in Switzerland, and the companies I wanted to serve — event organizers, NGOs, rental businesses across Europe — deserve better than having their operational data stored under a foreign jurisdiction.

I want to be honest with you.

Stockaj is built by one person. I write every line of code, handle every support message, design every screen, write every blog post, manage the infrastructure, and make every product decision. There's no team, no investors, no VC money. Just me, my laptop, and an unreasonable amount of coffee.
