The problem
- Event equipment rental companies (LED panels, speakers, truss, LED pars) track their stock on spreadsheets and paper.
- Contracts depended on the owner: with no template and no legal background, each one took 30 to 50 minutes, sometimes more.
- Without up-to-date stock, the same panel could be promised to two events on the same date.
- No proof that a contract had been accepted, and billing done by hand.
Discovery
Locacore started at a rental company I know closely, specialized in events. Following their routine, I saw that the biggest friction wasn't the event itself but everything before it: drafting the contract, knowing what was available and organizing the LED panels.
Talking it through, I found that partner companies and acquaintances of that business complained about the same things. I showed early versions to event producers and LED company owners, who liked the idea and said they would use it.
What it taught me
- 01The contract was the most cited pain: slow, and dependent on a single person.
- 02Every rental company has its own rules, so one standard contract doesn't fit them all.
- 03Few people adopt a tool just to get organized. They adopt what helps them sell more.
The solution
A platform that follows the rental from order to payment. The owner enters the booking once, and the stock reservation, the contract and the charge all come from it. A public storefront turns the system into a sales channel.
Decisions
01The contract comes from the booking
The owner wrote every contract from scratch, retyping the customer, event and equipment details.
The data already entered in the booking fills the contract, which is ready to send.
Why: The time went into drafting and retyping. Without those two steps, anyone on the team can generate the contract.
02Editable clauses
The first version had a single contract template for every rental company.
Templates with clauses each company can edit, while keeping automatic generation.
Why: It was the first request after the companies tried it: each business has its own rules and wouldn't accept the same contract as everyone else.
03From organizing to selling: the storefront
The product was only an internal management tool.
A 24/7 public catalog, with its own URL and the company's theme, where customers browse equipment and request a quote.
Why: A paid-traffic professional warned me that few people pay for something that only organizes; they pay for what helps them earn more. The storefront gives the company a commercial reason to use the system every day.
