reat question! Not all rental software charges a monthly fee—though most modern ones do because they operate as SaaS (Software as a Service). However, if you're looking to avoid recurring costs for your baby equipment rental business, there are still some solid options you can consider.

Your Options Without Monthly Fees:
1. Self-Hosted Open-Source Rental Software (One-Time or Free)
You install and run the software on your own server. This avoids ongoing fees but requires some technical setup.

Examples:
Equipment Rental Software – ERPNext (Free/Open-source ERP with rental module)
Pro: Free and customizable
Con: Needs hosting & setup knowledge

Sharetribe (Open Source version)
Pro: Made for marketplace-style rentals
Con: Technical to set up, paid version has a monthly fee

Booking Core
Pro: One-time purchase on platforms like CodeCanyon (~$60–$100)
Con: Might need tweaks for baby gear rental use case

2. Use a Website Builder + Booking Plugin (One-Time Plugin Fee)
You can build your site on WordPress or Webflow, then add a rental/booking plugin that charges once.

Example Stack:
WordPress + WooCommerce + WooCommerce Bookings plugin

Pro: Popular, lots of support, highly customizable
Con: Plugin may have a one-time or annual fee (~$250), but you can find lifetime deals sometimes

3. Offline Tools (Spreadsheet + Manual Process)
Not ideal if you want to scale or automate, but technically free or one-time purchase.

Recommendations for Your Baby Equipment Rental Business:
