Good day. I have created similar calculators (repair/window structures/modular buildings): logic based on a price list + formulas + final estimate.
Input dimensions: room + terrace
Choice of interior finishing (materials/packages)
Windows/doors: size, type, quantity
Stove: type/model
Final result: cost by items + total amount (can be broken down into "materials/labor")
Implementation options:
Embedded calculator on an existing website (JS)
Separate page/landing with a calculator
WordPress plugin/block (if the site is on WP)
Or a separate program for the office (if needed only for employees)
If you let me know where you plan to use it (public website or internal solution), I will suggest the optimal architecture, timelines, and budget.

Good day! I represent the Nexus Core team. We act as your personal IT department, handling all technical tasks related to the development of complex interfaces and calculation logic. We have reviewed your task of creating an accurate cost calculator for construction structures. We have experience in developing such systems and propose implementation on our preferred stack: Next.js 14, React, and TypeScript for the frontend, as well as PostgreSQL for the materials database. Instead of standard CMS, we will create a custom solution where the calculation logic will refer to a dynamic price list through an admin panel. This will allow you to independently update the cost of materials (finishes, windows, doors, stoves) in real time, and the calculator will instantly recalculate the total cost based on the dimensions of the room and terrace. We will ensure high performance, clean code, and full responsiveness of the interface for mobile devices and desktop. Before starting work, we would like to clarify a few points: is the function of generating a PDF estimate or sending the calculation result to email/Telegram necessary, is integration with your CRM required for transferring calculation data as a lead, and do you plan to add visualization of the structure (2D/3D) in the future? Our cases are protected by NDA, but in private messages, we are ready to discuss the architecture and logic of similar calculators. The final cost and timelines will depend on the complexity of your formulas and the volume of the materials list. Please write in private messages — we will clarify the details and provide a fixed cost with a breakdown by stages and agreed timelines.

Good day!
I am ready to develop a flexible calculator (interface, checkboxes, buttons) with a dynamic database. You simply substitute (upload) your price list and list of components. We will clarify the specific implementation.
From the assignment, I did not quite understand the necessary depth of calculations. But that's not a problem. I hope we will not be developing ArchiCAD from scratch. However, I will still incorporate scalability in this direction into the architecture of the application.
That is, the architecture of the solution assumes the possibility of scaling from a quick commercial estimate to detailed specifics based on the principles of specifications in professional engineering systems. That's it.

Hello! I am ready to implement a calculator with a flexible pricing adjustment system. I have experience in developing tools for calculations and data visualization.
How I will execute your task:
Architecture: I will create a separate configuration file (database or JSON/Excel spreadsheet) from which the calculator will take current prices. You will be able to easily change the cost of materials without editing the code.
Logic: I will define dependencies for each parameter: area of the room/terrace, types of finishes, specifications for windows, doors, and stoves.
Interface: I will create a clean and understandable form for data entry with instant recalculation of the total amount.
Estimated cost: from 2000 to 4000 UAH (there are a few more questions).
Timeline: 3 days.
I would be happy to review your list of materials to provide an accurate estimate. Let's discuss the details in the chat!

I have experience in developing web calculators for construction companies. I am ready to implement: input of the dimensions of the bath and terrace, selection of finishing, windows, doors, stove — with automatic calculation according to your price list. I am ready to start immediately after receiving the list of materials with prices.
Budget: 4600 UAH Deadline: 2 days
Good day! I can create a cost calculator for a frame bath according to your price list.
To ensure it calculates accurately, I suggest the following format:
You provide a table of materials/work with prices and rules (what depends on the area, what is fixed, what coefficients apply).
I will assemble the calculator with fields: dimensions of the room and terrace, interior finishing, type/size of windows and doors, stove — and the output will include the total + itemized details.
I would like to clarify 3 points to immediately provide an exact cost and timeline:
• where should the calculator operate (separate web page/widget on the site/Google Sheets)?
• is itemization of the estimate needed (materials/work separately) or just the total amount?
• will there be one fixed price or do you need to be able to change prices (for example, through a table/file)?
After your responses, I will provide the exact price and timeline, and I can start immediately.

Good day, Vladimir
I have created cost calculators for construction/engineering tasks where units, rounding, coefficients, and a transparent estimate are important — otherwise, managers cannot sell based on numbers.
I understand that you need a calculator for frame baths that calculates the price deterministically according to your price list: input of the dimensions of the room and terrace → selection of interior finishing → windows/doors (type + size) → stove → final cost. The key is that the calculation always matches your "material list with numbers," not "by eye."
Key logic/architecture:
Input parameters → normalization (areas/perimeters/number of items) → selection of rows from the price list (SKU/items) → calculation according to formulas (m², linear meters, pieces) → total + breakdown of "what it consists of" → (optionally) saving the application/calculation in a table/CRM.
Common breakdowns:
1. Price list without units of measurement/rounding rules → the total "floats."
2. "Windows/doors by sizes": a correspondence table of sizes to items in the price list is needed, otherwise, it becomes a manual nightmare.
3. Terrace/construction: often forget reserve coefficients, material multiples, minimum batches.
4. Without a breakdown, the client does not trust the number ("why so much?").
How I will do it:
1. First, we fix the structure of the price list: item, unit, price, rounding rule, coefficient (if needed).
2. I will create formulas in a separate configuration (JSON or Google Sheet) so that prices/coefficient can change without code editing.
3. Interface: a quick web calculator (JS/React) with clear steps and an "estimate" at the end (total + breakdown).
4. If desired: sending the result to you via email/Telegram + recording in Google Sheets.
1. Will the calculator be on the website or separately (landing page), or do you need a Telegram bot?
2. Do you have the price list in Excel/Google Sheets? And are there already ready formulas/rules for material consumption, or do they need to be gathered together?
3. Is a breakdown "estimate" (items and quantities) needed, or is just the total amount sufficient?
Timeline and budget: 3–6 days, 8,000–15,000 UAH (depends on whether there are ready formulas for consumption and how "sized" the windows/doors are with the matrix of options).
If you send the price list and examples of 2–3 calculations "as it should turn out" — I will fix the exact estimate and immediately assemble a prototype.

I need a program or Telegram bot for bulk creation of shipping documents through the Nova Poshta API.Main Task I upload 50–100 orders at a time into an Excel/Google Sheets/CSV table or paste a list of orders into the program. Clients provide data in different formats, so the system must automatically recognize the data, sort it into the necessary fields, and create shipping documents through the Nova Poshta API.Input Requirements Possible options: Upload an Excel/CSV file. Copy a list of orders into the program. Paste client messages in free format.What the Program Must Recognize From each order, it is necessary to determine: Recipient's full name; Phone number; City; Nova Poshta branch; Product/comment; Cash on delivery amount; Weight/dimensions, if specified.Operational Logic I upload 50–100 orders. The program processes each order. Data is automatically distributed into columns. The program checks the city and branch through the Nova Poshta API. If there is an error or missing data for an order, it highlights that order and indicates what needs to be corrected. If everything is correct, it creates the shipping document. After creation, it shows a list of completed shipping documents. It allows exporting the result to Excel.Output After Processing For each order, it is necessary to obtain: Shipping document number; Client's full name; Phone; City; Branch; Cash on delivery amount; Delivery cost; Status: created / error / needs verification.Mandatory Functions Bulk creation of 50–100 shipping documents at once; Verification of city and Nova Poshta branch; Ability to edit an order before creating the shipping document; Saving sender data; Working with cash on delivery; Exporting created shipping documents to Excel; Log of created shipments.Desirable Telegram bot or simple program for Windows; Excel/CSV upload; Ability to paste a list of orders as text; Saving a database of regular clients; Reordering with one click; Product and weight templates; Printing/downloading labels for packages.Important I need not just a form for manual filling, but a tool for bulk processing of orders. Main scenario: I upload 50–100 data entries, the program sorts the information itself, checks for errors, and bulk generates shipping documents through the Nova Poshta API.
