Bookinglayer is a booking and management platform built specifically for retreat centers, surf camps, outdoor operators, and wellness or boutique properties sell accommodation and activities together. No hotel PMS was built to sell nights in a room, with no way to schedule a lesson, cap a group size, or bundle a treatment into a stay. Operators end up running a second tool or spreadsheet for activities and reconciling everything by hand. with Bookinglayer, every booking is structured around the Package, combining accommodation, activities, meals, and services into one offering, whether that's a fixed date retreat, a flexible stay, or a surf week with fixed inclusions. Four core features cover the full booking lifecycle. The Booking Engine runs on the operator's own domain and branding, letting guests book accommodation and activities in a few clicks, which keeps drop-outs low and builds trust at checkout. The Backoffice is where staff manage inventory, bookings, and reporting from one place, with information like a dietary requirement reaching every relevant team member automatically. The Customer Portal lets guests confirm details, pay balances, sign waivers, and adjust activities themselves, removing the manual follow-up that used to consume staff time between booking and arrival. Payments runs deposit and balance schedules automatically across more than 35 gateways, so payment tracking stops depending on manually checking a bank statement against a spreadsheet. Every booking made through the Booking Engine is direct, with no marketplace commission, unlike the 15 to 20% typically charged by third-party channels, and guest data stays with the operator. Support is included 24 hours a day with every account, and pricing follows the same logic: every account gets the same core platform, then operators add only what they need: more users, extra locations, advanced features, or API access. The numbers reflect the mechanism. Clients save at least five hours of admin work per week and increase average booking value by 30% through structured upselling. More than 1,500 properties across 85+ countries and 40+ niches run on Bookinglayer, with over 1.5 billion dollars in bookings processed and 95% client retention across more than a decade in business.

Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability.
