The development benchmark is 48,000 UAH. Deadline - 14 working days after access to the landing code, agreement on the logic of schedules and service structure.

For data storage, I would suggest Supabase on the free plan. It’s PostgreSQL, ready-made API, and admin panel, and most importantly - it can properly implement !!protection against double booking!! through constraints in the database and server-side validation. Google Sheets is riskier here because with simultaneous requests, it’s easy to get two entries for the same time.

I envision the implementation as follows -
> a database with categories, services, masters, schedules, periods of unavailability, and bookings
> a form on the website loads data step by step - category - service - master - date - time
> creating a booking goes through a secure request that checks for an available slot and blocks it
> a separate simple admin page for editing services, masters, schedules, vacations, and bookings

Hello! I am interested in your project to create an online booking form for a beauty salon. I have extensive experience in developing interactive web interfaces and setting up integrations with cloud services. Since you do not plan to deploy a separate database, I suggest using Airtable or Google Sheets as an effective and free tool for storing applications. This will allow you to conveniently manage bookings through a simple interface.

I recently left a large IT company where I was involved in developing high-load systems, and I am now transitioning to freelancing. Currently, my priority is to build my portfolio and receive positive feedback on this platform, so I am ready to complete your order with the highest quality at a significantly lower price.

Please let me know:
1. Which messenger or notification system would you like to use for receiving new bookings (Telegram, Email)?
2. Do you already have design mockups for the form, or do I need to style it according to the current landing page?

I would be happy to help with the implementation!

If needed, administration can be done directly through the browser, and in the future, it is easy to add a separate convenient admin panel without changing the database structure.

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;

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.

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.

Good day!

For this task, it is better to separate the public form on the landing page and a separate backend for data storage and booking logic. From a technical point of view, the most practical free solution for an MVP is Supabase: it provides PostgreSQL, API, a basic admin panel, and is well-suited for entities like categories, services, masters, schedules, vacations, and appointments without having its own database on the main site.

The key point here is not in the layout, but in server-side availability checks. Slots need to be counted on the backend side, and creating an appointment should be done atomically; otherwise, there is a risk of double booking with simultaneous requests. It is also worth immediately laying out a model for individual schedules and periods of unavailability, as this part usually complicates maintenance after launch.

As for the timeline, the estimate is 14–18 working days for implementing the form, data structure, admin logic, slot checks, and testing booking scenarios. Regarding the cost — 18,000 UAH. If additional notifications are needed via email or Telegram, as well as initial data filling, it is better to clarify this separately before the final assessment.

To fix the architecture without unnecessary rework, it is important to understand just two points: whether notifications to the client and administrator are needed after creating/canceling an appointment, and whether there are already prepared lists of categories, services, masters, and their schedules. If there are, then integration can be done without tying to a heavy CMS and with a normal margin for scaling.

A registration form is needed with cascading filters, slot blocking, and a simple admin panel — without a dedicated server.

For data storage, I suggest using Google Sheets as a free database via the Apps Script API: categories, services, masters, schedules, records — separate sheets, accessible through REST. The form in pure JS will be embedded in the landing page as a web component. Protection against double booking will be implemented through transactional checks upon submission — reading + writing in one Apps Script request with a lock service. The admin panel will be a separate protected HTML page with a password, where the admin manages all directories and records.

Please let me know: how many masters are planned and whether automatic notifications to the client (SMS/email/Telegram) are needed after booking?

Good day, Yulia

At first glance, the task seems quite simple, but the main difficulty of such systems is not the form of recording itself, but the correct logic of the schedule to avoid double bookings and accurately account for the schedules of the masters.

For such a project, I would suggest using Supabase as a data storage solution. This is a free solution for small projects that does not require a dedicated server, has PostgreSQL, a ready API, and is well-suited for similar booking systems. It can also be used in the future to expand functionality without changing the architecture.

I would like to clarify a few points:

1. Do the services have different durations, and should the entire time interval for the service be automatically blocked?
2. If two users select the same time simultaneously, what scenario should occur?

Good day. Of course, data parsing from a file can be done, but many nuances and consequences need to be considered regarding what this may lead to. For example, the data will not be indexable. This means there will be a long search through the file for the required data if there is a plan to implement the site on hosting for more than 50 users. The ACID (Atomicity, Consistency, Isolation, Durability) principles of data may also be violated. There are also many other mechanisms that are implemented in database systems, and they affect the security of user data and processing speed. Moreover, first and foremost, this is your security. If the data is obtained from this file, there will be a leak. To avoid all these issues, it is necessary to create an analog to databases. Alternatively, MongoDB can be used (to avoid MySQL injections). There are also NoSQL injections, but they can be easily bypassed. If a system without a database is absolutely necessary, we can discuss it personally.

From the implementation side, I would create a booking form, a small admin panel, tables for services, masters, masters' schedules, unavailable periods, and a booking log.

Hello. The task is absolutely clear. I specialize in developing custom booking systems and have a ready vision of how to implement this reliably and without subscription fees.
Here is the solution I propose for data storage and administration:
Since you need a free but stable backend, the ideal option would be a combination of Supabase (PostgreSQL) and Next.js.
1. Database and API: We will use the Supabase cloud database. Its free tier will be more than enough for the full operation of the salon.
2. Admin panel: I will develop a separate, user-friendly web admin panel on Next.js for managing appointments, masters, services, and flexible schedule settings (working hours, vacations, weekends). We will host it on the free Vercel hosting — you will not pay for servers.
3. Integration into your current website: For your HTML/CSS/JS landing page, I will write an isolated JS module (script). It will handle all the complex logic: step-by-step loading of categories, calculating available time based on the master's schedule, and strict blocking of slots from double bookings. Your front-end developer will only need to connect this script and apply the necessary CSS styles to it.

Hello!
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.

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

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.

Good day, Yulia.

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.

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. That is, there are solution options. And many. If you reply, we can discuss.

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.

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.

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.

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
