Good day, I can implement online booking so that it works reliably without a dedicated database on the site. I will offer a free solution for storing and managing data, set up the dependencies category → service → master, a calendar of available slots, and protection against double bookings. I will also provide management of schedules, days off, and client bookings. I have 8 years of experience in web development, so I can quickly assemble the working functionality. After clarifying the details, I will provide exact timelines and the scope of work.

Hello, Yulia! I fully understand the task. I am ready to develop such an interactive online booking form and integrate it into your existing landing page.
Since a classic database is not planned, I propose an ideal and completely free solution for the beauty industry — to implement the backend based on Google Sheets (or Airtable).
Administration: You and your masters will be able to manage the schedule and see new bookings directly in a regular table on your phone. This is maximally simple and stable.
Form logic: The script on the site will dynamically pull categories, services, and available time slots of a specific master from this table. Upon successful booking, the time is automatically blocked, completely eliminating double bookings.
I will make the form fully responsive so that clients can easily book from their smartphones. Write in the chat, and we will discuss the details; I am ready to get started!

Good day, Yulia!
I can implement a functional solution for you without relying on a "heavy" server-side part of the site. For such a project, I propose a free cloud solution for data storage with a simple admin section: it will be suitable for a landing page on HTML/CSS/JS, will not require a separate database on the site, and will be convenient for daily management of records.
What I will do:
— an online booking form with step-by-step selection: category → service → master → date → time;
— logic to display only those masters who perform the selected service;
— a calendar of available dates and free slots according to the schedule of a specific master;
— creation of a record with time blocking;
— protection against double booking at the level of record logic;
— admin management of categories, services, masters, schedules, days off/vacations, and the records themselves.
An important point: it is not enough to just "store requests" here. It is necessary to correctly build the data structure and checks so that free time is accurately calculated considering the schedule, unavailable periods, and already created records. This is where I focus my main attention.
I will make the integration so that the front-end developer can easily connect the form to your current design without reworking the entire logic.
If you want, I can briefly describe in the next message how the data structure will be organized: categories, services, masters, schedules, and bookings.

Good day.
The categories are indicated quite correctly. To implement such functionality, JavaScript and integration with a third-party database are required.
I have relevant experience in solving similar tasks. Recently, I developed the logic for hourly booking fields for a home cleaning service. I fully understand all the nuances of working with master schedules and reliably blocking occupied slots.
For free data storage, I suggest using Firebase from Google. It has a large free limit and provides instant information updates in real-time. This guarantees absolute protection against double booking of clients for the same time.
For convenient administration, I will create a separate hidden page on your website. There, you will be able to easily add services, edit master schedules, and manage vacations. All changes will be immediately reflected in the client online booking form.
The estimated cost of development will be 5000 hryvnias. The execution time will take about 6 days. I am ready to discuss the details and start working.

Good day! I created online booking forms for salons — selecting a category, then services, the master, and available time with step-by-step loading. It's convenient to keep the database for this in Google Sheets via Apps Script: free, stable, and editable directly in the spreadsheet. Let me know if you want to manage the masters' schedules and days off in the same spreadsheet? I can take it on, approximately 3-4 days.
Budget: 6000 UAH Deadline: 6 days
Good day, Yulia!
The most challenging part of your task is not the form itself, but the protection against double booking. This is where most solutions fail, so I will start with it.
What I propose for data storage: Supabase, free tier. This is a regular PostgreSQL that immediately provides a ready REST API, so a separate server and hosting fees are not needed. Why this and not tables? I close double booking at the database level with a unique index on the pair "master + date-time." If two people click "Book" at the same second, the second entry will not be physically saved, and the person will immediately see that the time is already taken. Google Sheets does not provide such a guarantee: there, a race of requests will sooner or later result in a double entry, and you will find out about it from two clients who arrived at the same hour.
Data structure: categories, services, masters, the link "master ↔ services," work schedule of each master, periods of unavailability (days off, vacations), and actual bookings. Free time is calculated as the master's schedule minus already occupied slots minus unavailable periods. Exactly the logic you described.
Administration: a separate simple page under a login. There, categories, services, masters, schedules, and days off are edited, and client bookings can be viewed and canceled. I consciously make it for the salon administrator, not for the developer: no technical panels.
I will provide the form as a self-sufficient module (HTML + JS), without tying it to the design. Your layout designer will connect it and dress it in the required design.
Cost: 6000 UAH. Deadline: 6 days.
I am currently gathering initial feedback on Freelancehunt, so I am taking it at a starting price. For such a volume, it usually costs more.
One clarification regarding the essence. Do you have services of varying durations (conditionally manicure 60 min, coloring 180 min)? This affects the time grid: a fixed step every 30 minutes or slots whose length is calculated from the selected service. This impacts the entire logic of free time, so I want to lay down the correct option right away, rather than rework it later.
I have live demo recordings for the salon and barbershop, ready to share in the chat so you can test the flow before making a decision.

Ready to create an online booking system so clients can see available hours without double bookings, while the administrator has everything under control.
The form will be in pure JS — with a cascade: category → service → master → available date and time. Data storage without a personal server — Firebase/Firestore: free, fast, nothing to maintain.
✅ Everything in the database will be correct: blocking occupied time immediately after booking, an admin panel for viewing and managing requests. Data will be organized — no one will "lose" a booking.
I created a similar system for a beauty salon — there are over 200 active bookings every month working without failures. So I know where the pitfalls are: I will immediately fix time zones to your locale and will validate phone numbers on the fly.

I have over 8 years of experience in commercial development and can implement this task. I can add data processing that will be sent and stored. I believe you are using NodeJS on the server for processing. I can write the processing in many languages. I have experience in implementing various tasks in different languages. You can use a single-file SQLite database, which is a file that does not require a web server. However, it can be used fully, and it has all the necessary functionality that exists in MySQL and PostgreSQL databases. SQL is used for operations. For data retrieval. If there is no driver on the server, I can write a Go program and add a service that will read and write using data transmission through shell.

Good day. I reviewed the technical specifications: a recording form with a cascade of category → service → master → available dates/times, plus slot blocking during booking and protection against double booking. Since there is no own database and none is planned, I suggest using Google Sheets as storage (via Google Apps Script as API) — free, transparent in administration (masters and categories can be edited directly in the table), and I will also create a separate tab for the work schedules of masters, days off, and vacations. On the front end, I will make calls via fetch to the Apps Script web application, with a check for slot availability before booking, to avoid collisions during simultaneous bookings. For viewing/editing/canceling client bookings, I will create a simple admin panel on top of the same table. The estimated completion time is about 5 days. Please clarify: how many masters and services should be included in the structure initially?

Hello!
I have worked on a similar online booking system for a restaurant — I implemented an interactive booking window, automatic table allocation, and time blocking. The system handles high loads: it receives about 40 bookings daily, and over the past month, more than 1400 entries have successfully gone through the system. Everything works quickly and correctly, with a configured automatic Email sending of notifications and reminders for guests. An Admin Panel for editing has also been developed.
For your project, I plan to use Supabase as a powerful and free alternative to traditional databases (with a built-in admin panel for you), as well as the Resend service for instant and uninterrupted Email notifications to clients and to you as needed.

Data storage: Google Sheets (completely free).
Why this is good: Ideal for clients who do not want to learn to work in new systems. Administration (adding categories, services, masters, and viewing records) takes place in the familiar Excel/Google Sheets interface.
Protection against double booking: Implemented using LockService in the script. This is a special tool that blocks access to the script for other users for a few seconds while the current booking is being processed.
Administration: Setting work schedules, vacations, and days off is done on separate sheets of the table. The script automatically calculates free hours by subtracting occupied slots from the master's work schedule.

Yulia, good afternoon!
The main risk for you in this task is not the form itself, but ensuring that you don't have to contact the developer for every little thing (new master, schedule change, new service). Therefore, I suggest using Google Sheets + Google Apps Script: you can manage everything directly in the spreadsheet you already know — just add a row in the "Masters" sheet or adjust a cell in the schedule, and everything updates without separate panels and logins.
In the spreadsheet: the master is linked to the list of services they provide; the work schedule and days off/vacations are separate from the actual bookings. Free time on a specific date is calculated as the master's working hours minus already occupied intervals minus periods of their absence.
I handle the uniqueness of the booking (deduplication) through LockService in Apps Script: during the booking process, it locks the spreadsheet for milliseconds while checking and recording the selected slot, so the second client will see "occupied" even before saving, not after.
I will create the form as a standalone module (HTML + JS), without tying it to the design — whoever is developing the site can simply connect it and style it as needed.
One important clarification: do you have services of varying durations (for example, manicure 60 minutes and coloring 180 minutes)? This affects how to build the free time grid — with fixed steps of 30 minutes or with slot lengths specific to each service.
Budget: 8000 UAH Deadline: 7 days
Hello! I am ready to develop an online booking form with the necessary functionality and connect it to your website. I will set up convenient data storage, a schedule for the specialists, and manage bookings without unnecessary complications. I will perform the work with quality, always be in touch, and will start working immediately after our discussion.
Budget: 5000 UAH Deadline: 6 days
Good day.
Your task is more about the correct logic of booking than about the form itself. The most important thing here is to accurately calculate the available slots considering the master’s schedule, days off, vacations, and already created appointments, as well as to ensure protection against double booking even if two clients choose the same time simultaneously.
For this project, I suggest using Supabase. It is a free PostgreSQL with a ready-made API and built-in admin panel. There is no need for a separate server or a custom database on the site, and administration remains simple.
I will implement:
- cascading selection of category, service, master, date, and time
- automatic display of only available slots
- creation of an appointment with atomic time locking
- protection against double booking at the database level
- management of categories, services, masters, schedules, days off, vacations, and appointments
- integration into your existing HTML, CSS, and JS without being tied to the design
There is one important point to consider before starting development. If the services have different durations, the algorithm for forming available slots will differ. It is better to lay this out from the beginning to avoid reworking the system in the future.
The estimated cost of development is 5000 UAH.
The completion time is about 6 days.
So that you can assess the approach without risk, I will prepare a prototype of the database structure for free and implement the first cascading selection of category → service. If the solution suits you, we will continue the development of the entire functionality.

Hello, I am a web engineer with 5 years of experience. I have worked on complex projects of various kinds, including embed forms.
In your situation, it won't be completely free. To store records securely, you need a database.
I suggest Supabase as the easiest and fastest way to connect to a database.
The plan will cost about $25 per month, but this is considering that the free tier won't be sufficient for you.
You will only need to create the form and connect the database.

The optimal free solution is Supabase: PostgreSQL with REST API and a built-in admin panel that connects to an HTML/JS landing page without a dedicated server. Your person who does the layout will receive a clean JS module with a cascade of category → service → master → dates → available slots — and will be able to design it in the required style without limitations.
Double booking is excluded by atomic slot locking at the database level: the transaction checks availability and fixes the time in one operation. The schedule, weekends, and vacations of the masters are stored separately, so the client always sees only the actual available hours.
Management of categories, services, masters, schedules, and bookings is done through Supabase Studio, just a few clicks without technical knowledge.
Options:
4000–6000 UAH; ≈5 days

Work without a database is possible. For this, it is necessary to have a complete list of all selected items. Then it is possible to store the set of all these items directly in the body of the page, hiding the unnecessary and displaying the necessary. But here, an external editor for these items needs to be thought out. Alternatively, everything can be run from the disk using AJAX, which increases the share of JS and AJAX code.

The task is clear — a website in pure HTML/CSS/JS, no separate database is planned, a simple and free solution for data storage is needed.
For this scenario, Google Sheets is optimally suited as a database in conjunction with Google Apps Script as the backend. It is free, stable, and the admin manages the data directly in the spreadsheet without any separate panel. The form on the website calls the Apps Script via fetch, the script reads and writes to Sheets, blocks time after booking, and checks for conflicts before creating a record. The schedule of masters, days off, and vacations are separate sheets in the same spreadsheet, which the admin edits themselves.
One clarification: are automatic notifications needed for the client or the master after booking (SMS, email, Telegram)? This can be implemented within the same architecture but affects the scope of work.
Deadline — 7–10 days.
Budget: 3000 UAH Deadline: 10 days
For data storage, I suggest Supabase — a free PostgreSQL database with a built-in admin interface and REST API. It connects to your HTML/JS landing page without a dedicated server, is easy to administer, and stable in operation.
I implement a full cycle: cascading lists (category → service → master), displaying available slots according to each master's schedule, and blocking time when booking. Protection against double bookings is handled at the database transaction level — this is more reliable than front-end checks and eliminates race conditions during simultaneous bookings.
Administration can be done either directly through the Supabase Dashboard (for free, without unnecessary development) or through a separate simple web panel for managing masters, schedules, days off, and client bookings.
Estimated volume — about 30-35 hours. The exact cost will be agreed upon after clarifying details: the number of masters, nuances of schedules, and the scope of the admin panel.

Good day!
The task is clear: an online booking form with the logic master → service → available time, protection against double booking, without a personal database.
Data storage solution: Google Sheets + Google Apps Script - free, stable, easy to administer. The administrator sees all entries in the table and can edit/cancel directly in Google Sheets. Masters, services, work schedules - separate sheets in the same table. Apps Script acts as an API between the form and the table.
How it works:
The client selects a category → the form pulls services of that category from Google Sheets
Selects a service → masters who perform it are pulled
Selects a master → the system checks the schedule and already occupied slots, showing only available time
The client fills in the data and confirms → the entry is saved, and the time is blocked from double booking
I will do it this way:
Google Sheets structure: Categories / Services / Masters / Schedules / Records - 5 sheets
Google Apps Script: API endpoints for reading data and recording bookings
JS form: chained dropdowns, date and time selection, submission and confirmation
Protection against double booking - check at the Apps Script level before saving
Preparation for insertion into an existing HTML/CSS/JS site - form as a separate JS component
Cost: from 4,500 UAH / Deadline: 6–8 days.
Send details on the structure of services and the number of masters - let's get started.

Protection against double booking will be implemented by checking the occupied slot at the registration stage (locking the row/script-lock in Apps Script) before the registration. I will create an admin panel with separate sheets in the spreadsheet: categories, services, masters, work schedules, weekends/vacations, client bookings (with the ability to edit and cancel). The estimated completion time is approximately 4 days, and I will specify the cost in a separate rate field.

Good day.
I can do it for a symbolic reward after the work is accepted. (new to freelancing, need to build a rating)
I have 4 years of experience in full-stack.
We can discuss the details.

Good day. I looked at the technical specifications — the task is clear: a cascading form (category → service → master → date/time) with slot blocking during booking, plus an admin panel for masters, schedules, and vacations. Since there is no database and none is planned, I would suggest Google Sheets as storage (via Google Apps Script as backend API) — this is free, the client will be able to edit categories, services, masters, and schedules directly in the spreadsheet without a separate admin panel, and I will implement the logic to protect against double bookings and check occupied slots on the script side. I will integrate the form into the already prepared layout of the landing page without touching the design. Records, cancellations, and viewing bookings will also be done through the same spreadsheet with simple statuses. The estimated timeframe is 3 days, and I will specify the cost in a separate field for rates.

Good day.
There is a ready solution, it was developed for another client, I can easily adapt it for you.
