Overview

About This Project

Slotwise gives every service business its own online booking page. Customers pick a service, a team member and a time that is genuinely free, pay a deposit by bKash, Nagad or card if one is needed, and get a confirmation and reminders by SMS and email — in English or বাংলা, without downloading an app or creating an account.

Behind the page, each business runs its day from one console: a drag-and-drop team calendar, appointments and customer history, payments with transaction-ID verification, reviews, a waitlist that fills cancelled slots, reports and role-based access for owners, front desk and team members. The platform owner manages plans and billing approvals, industry templates, message templates and every word on the marketing website from a super admin panel.

The Challenge

Most salons, doctors' chambers and studios in Bangladesh still take bookings over the phone and in a notebook: staff lose hours answering calls, the same slot gets promised twice, customers forget and never show up, and advance payments by bKash are checked by scrolling through message history. International booking tools rarely fit local habits — mobile banking deposits, Bangla pages, SMS gateways and weeks that start on Saturday.

Our Solution

We built a multi-tenant platform where one booking engine serves every channel — the public page, the website widget and the console. It computes free times in each business's own timezone, locks team members while a booking is saved so a slot can't be taken twice, and fans every change out to messages, the calendar, webhooks and the waitlist. Payments recompute the balance from a ledger, SMS use prepaid credits, and each business starts from an industry template with services, hours and wording that already fit.

Results

  • Customers book 24/7 in under a minute from Facebook, Instagram, Google or the business's website
  • The calendar only offers times that are really free, so double-bookings disappear
  • Two automatic reminders per visit and upfront deposits cut no-shows
  • bKash and Nagad transfers are verified in one click instead of scrolling through messages
  • Owners see revenue, busy hours and team utilisation without spreadsheets
