A scheduling SaaS, built in-house from scratch.

SyncSlot is a scheduling tool that syncs with Google/Outlook calendars and automatically suggests open time slots. Guests book in one click, and web-meeting URLs are issued automatically.

Calendar sync, availability booking, web-meeting issuance, and subscription billing — the story of launching a multi-tenant SaaS by building, in-house from scratch in 14 months, a platform that satisfies all four axes a scheduling SaaS demands at once.

CHALLENGE

The design challenges to solve

The four structural requirements the SaaS had to meet.

None of these were technology-selection issues; they were business requirements tied directly to productivity, customer experience, and revenue. Building anew from scratch required a design that satisfies them all at once.

Email back-and-forth for scheduling

Relying on back-and-forth over dates means endless rounds per booking — wasted effort and lost opportunities.

Calendar double-booking

Without auto-synced availability, double-booking erodes trust.

Manual web-meeting URL issuance

Issue meeting URLs by hand and setup errors and manual effort erode the booking experience.

Subscription billing operations

Rely on manual billing and invoicing and operating costs become a drag on scaling.

ARCHITECTURE

The architecture we built together

Turning a scheduling SaaS into a scalable platform across four domains.

We built four domains — calendar integration, booking, web-meeting issuance, and subscription billing — in-house from scratch with React + Laravel. By integrating the Google/Outlook/Zoom/Stripe external APIs, we delivered a multi-tenant platform that scales securely.
