Online booking systems for marketplaces.
Every missed call is a booking that went somewhere else. Online booking lets a customer choose a service and a time on your website in under a minute, at midnight if that is when they are free, and it keeps your calendar honest without a receptionist in the loop. We build custom booking flows when off-the-shelf schedulers cannot express your rules, working remotely from our Providence, RI studio. A marketplace is less a website than an economy with a storefront on top. Sellers need onboarding, listings, payouts, and a dashboard worth opening; buyers need search that works, a cart that handles several vendors in one payment, and enough visible trust to pay a stranger. The build serves both sides, and neither should feel the weight of the other. For service marketplaces, booking is the core transaction: a buyer picks a provider, sees that provider's real availability, and pays through the platform, which holds the funds until the service is delivered. Providers manage their own calendars inside the same system.

Connects to the tools marketplaces already use.
Online booking builds earn their keep when they stop double entry. These are the integrations we most often scope for marketplaces; if your stack is different, we map it in discovery.
Why marketplaces reach for this.
Sellers who list once and never come back
A clunky onboarding form and a dashboard that buries orders leave vendors with half-finished shops, and thin inventory is the first thing a buyer notices.
Checkout that splinters across vendors
When items from three sellers turn into three separate payments, three shipping estimates, and three confirmation emails, the cart is abandoned before the last one loads.
Trust that has to be earned twice
A buyer is trusting the platform and a stranger at the same time, and without visible seller profiles, reviews, and a plain-language dispute policy, neither side feels safe enough to transact.
Online booking builds start from $8,000. Every project is quoted to its scope.
