Everything is great, the performer does their job qualitatively and professionally, understands everything with half a word, without unnecessary questions. During the work, there was a nuance with the iOS app (publication in the App Store), but this is not the fault of the performer. For the future, Maxim promised to help with the completion of the publication, I am confident that he keeps his word! Thank you.

The benchmark is 280,000 UAH and 35 days. It can be completed in 30 days if the first version is made without complex offline logic and without separate native development for each platform. I would rather simplify it - an adaptive web application or PWA for phones, a web admin panel, and a server database, while using Google Sheets and Excel for automatic synchronization and export, not as the main storage. For 300 users, this is important because a spreadsheet alone cannot handle normal roles, blocking, action history, and stable reporting.
I suggest going through short project planning, then a working scanning prototype, followed by the admin panel, reports, and synchronization. Scanning barcodes through the camera can be done without a separate scanner, but it needs to be confirmed which codes are used - EAN, QR, Code 128, or mixed.
> Question 1 - Are the products already in Excel or Google Sheets with codes, prices, and articles, or do we need to import from scratch?
> Question 2 - Should sales work without the internet with subsequent synchronization, or will the internet be constant?

Overall, a normal scale for MVP. I would just not tie the core of the system to Excel as a database - it is cheaper at the start, but later affects stability. A penny-wise person pays twice, and in accounting systems, this folk wisdom, unfortunately, too often passes the test of reality =/

Here I have a similar accounting system - but on a proper DBMS, not Excel - and I can say that in 30 days (or even 100) you can only create some strange nonsense, an unworkable accounting system.

Hello.
The scope is clear. Scanning barcodes through the phone camera, registering sales with quantity and price, synchronization with Google Sheets or Excel, web admin panel for the admin (users, sales, exports). Up to 300 users, roles of seller and admin.
The approach I propose. The mobile part — React Native cross-platform (one codebase for Android and iOS). Scanning through react-native-vision-camera, works reliably with standard barcodes (EAN-13, UPC, Code 128). For 300 users and a simple flow (authorization, scan, confirmation, history), cross-platform is the optimal choice.
Backend — Python with FastAPI, Postgres for the product catalog and sales log, JWT authorization with role separation.
Sync with Google Sheets — a separate worker that takes records from the database and pushes them to the required table in real-time via Google Sheets API on a service account. Excel export as a separate button from the admin panel on request.
Web admin panel — users, sales, filters and search, import catalog from Excel, export. Built on top of the same FastAPI plus a simple front end.
Two questions to clarify the timeline. Will the product catalog be uploaded by the admin from Excel in bulk right away, or is there a plan to integrate with some existing product system (1C, CRM, e-commerce)? Is it critical for the mobile client to work offline?

Good day.
We are engaged in the development of mobile and web systems for business using the Laravel/Flutter stack and can implement a "turnkey" solution — a mobile application for sellers + a web admin panel for managing sales, products, and reporting.
For the backend, we offer Laravel + Filament — this allows for the quick implementation of a stable admin panel with convenient data management. The mobile application will be built with Flutter for Android and iOS, featuring barcode scanning through the camera.
Before the final assessment, we would like to clarify a few points that affect the scope of work:
— Is there a ready design (Figma) for the mobile application?
— Is there already a product database, and in what format is it stored (Excel/other system)?
— Is there a need to work with serial numbers (IMEI) for products?
— Is an offline mode required for the mobile application?
— Should there be two-way synchronization with Google Sheets, or just data export?
Estimated assessment:
— backend + admin panel (Laravel + Filament): ~120 hours;
— mobile application (Flutter iOS/Android): ~160 hours.
In total: ~280 hours of work.
Rate: $20/hour.
We would be happy to discuss the details and clarify the final scope before starting.

Hello.
I have extensive experience in developing mobile applications and complex accounting web systems. I will implement this ERP system "turnkey" strictly within the specified requirements.
To meet the desired deadline of 30 days and ensure functionality on Android and iPhone, I suggest using a cross-platform framework like React Native or Flutter. The backend will be implemented on Node.js, and synchronization with Google Sheets will be set up via the official API — data from 300 users will be transmitted instantly and without delays.
All development will be conducted through your GitHub, and we will deploy the databases on your accounts.
I can provide an estimated cost for developing such an MVP in the chat after a brief discussion of the product database structure. I have attached my portfolio below. Message me, and we will discuss the details!

Hello. The task is completely clear. The functionality you described is a classic but very effective POS system for automating retail sales. The desired timeframe of 30 days is absolutely realistic for the development and testing of such a turnkey product.
I propose to implement this project as a progressive web application (PWA) or a Telegram Mini App with a backend in Python. This will allow your employees to work reliably from any smartphone. For the scanning module, we will connect a fast native scanner that will instantly read barcodes or QR codes through the device's camera, record the sale in the database, and display it in the history.
I will make the admin panel concise and user-friendly: with user role separation, a sales log, and visual statistics graphs. The Excel integration module will be set up with strict data validation: the system will automatically check uploaded files for formatting errors before updating the inventory to avoid accidentally corrupting the database, and report exports will be generated with one click.
From a technical standpoint: a basic server and a domain with a secure SSL certificate will be required for launch, as access to the camera for scanning works exclusively through a secure https protocol. I will fully assist with server setup and site deployment.
The estimated cost for developing the entire system with the admin panel and import modules is 18,000 UAH ($450). The implementation and testing will take about 15-20 days, so we will definitely meet the schedule. Please let me know if your products already have ready-made barcodes from the manufacturer, or if they need to be generated additionally within our system? I am ready to discuss the details and start working.

Hello!
My name is Daryna, I am a Python developer specializing in business process automation, working with APIs, and creating data accounting systems. Your specifications are extremely well-written, and I fully understand the task.
I am ready to implement this system "turnkey." Since the deadline is limited to 30 days, and the system needs to work on both iOS and Android, as well as on PC (for the admin), I propose developing a mobile-adapted Web application (PWA) based on Python (FastAPI or Django).
💡 Why is this the best solution for your case?
Cross-platform: One application will work everywhere. Vendors will open links on smartphones (both iOS and Android), add an icon to the desktop, and work just like in a regular application. The admin will access the same system from a PC but with extended rights.
Camera scanning: I will integrate a modern JS library for working with the smartphone camera. It will instantly read barcodes, recognize the article, and through AJAX/Fetch, pull the name, price, and stock of the product from the database.
Synchronization with Google Sheets: I will set up the official Google Sheets API. Each sale will automatically be recorded as a new row in your table in a fraction of a second. No delays.
Speed of development: This approach will allow us to fully meet your 30-day timeline and ensure stable operation for 300+ users without the need to publish applications in the App Store and Google Play (which usually takes weeks just for moderation).
🛠️ What functionality will I implement (according to your specifications):
Authorization and Roles: Reliable password encryption, clear division between Admin and Vendor (with logging of ID, date, and time of each action).
Mobile interface: Concise 4 screens (Login, Scanner, Confirmation with quantity selection, Session history).
Admin panel: Full-fledged web cabinet (user management, blocking, sales filters by dates/vendors, analytical graphs-reports).
Import/Export: A module for uploading your product database from Excel and exporting ready reports in .xlsx.
⏳ Timeline and Budget:
Timeline: 20–25 days for development + 5 days for testing and fixing comments (we will clearly fit into 30 days).
Budget: I am ready to discuss individually after a brief call or correspondence, as the Python solution saves you budget compared to native mobile development significantly.
Clarifying question: Please let me know, is the product database (names, codes, prices) currently also stored in Excel/Google Sheets, or will it need to be uploaded to a separate database (for example, PostgreSQL/SQLite) within the system?
