Simple Windows Purchase Invoice & ID Scanning Application I am looking for a developer to create a simple, easy-to-use Windows desktop application for our scrap metal business. We occasionally purchase scrap metal/goods from members of the public. We do not require customer accounts, CRM functionality or a complicated database. The system needs to be extremely quick and simple for staff to operate. Required Workflow 1. Create Purchase Invoice Staff open the application and are presented with a simple purchase invoice screen. Each new transaction should automatically receive the next sequential invoice/transaction number, for example: 000124 000125 000126 Staff should not normally need to manually enter or change this number. The invoice should contain fields for: - Date/time – automatically generated - Invoice/transaction number – automatically generated - Seller's name - Seller's address - Description of goods/material - Amount paid - Possibly vehicle registration (I would like the ability to include this) There should then be a simple SAVE & PRINT button. This should save an electronic PDF copy of the invoice and print a paper copy of the invoice. After completion, the next transaction number should automatically be generated. 2. ID Scanning We need to electronically retain a copy of the seller's identification, normally a: - UK driving licence - Passport We are considering using a Plustek SecureScan X50 passport/ID scanner, although I am open to advice from the developer if another scanner would integrate better. I would like a SCAN ID button within the application. The important requirement is that the scanned ID is automatically associated with the current invoice/transaction number. For example, transaction 00124 could automatically create: 00124/ - [login to view URL] - [login to view URL] or [login to view URL] Then transaction 00125/ would contain: - [login to view URL] - [login to view URL] or [login to view URL] Staff should not have to manually name, rename or move scanned files. 3. Simplicity This is very important. The application will be used by staff who are not particularly technical. Ideally the main screen should contain the invoice fields and only a few obvious buttons such as: SCAN ID SAVE & PRINT NEW TRANSACTION REPRINT / FIND PREVIOUS TRANSACTION We do not require customer accounts or a complicated accounting system. 4. Record Storage & Security Because passport/driving-licence images will be retained, I would like the developer to recommend a sensible and secure method of storing and backing up the records. The system should make it easy to retrieve an old transaction using its invoice number. Existing completed invoices/ID records should not be accidentally overwritten or deleted by staff. 5. Equipment / Integration The application will run on a dedicated Windows 11 laptop/PC. The developer should be comfortable integrating: - Passport/ID scanner - Standard office printer - PDF generation - Windows file/storage system Experience with TWAIN/WIA and/or scanner SDK/API integration would be beneficial. We are currently considering the Plustek SecureScan X50, so please mention whether you have experience integrating Plustek scanners or similar passport/ID scanners. Deliverables I would like: - Finished Windows application - Invoice template/design - Automatic sequential invoice numbering - PDF generation - Printing - ID scanner integration - Automatic matching/naming of ID scans to invoice numbers - Search/reprint previous transactions - Secure local record storage - Backup/recovery recommendations - Installation/configuration assistance - Full source code supplied to us - Basic instructions for using and maintaining the application I would prefer a fixed-price quotation for the complete project. When applying, please explain: 1. What technology you would use to build it. 2. Whether you have previously integrated document/passport/ID scanners. 3. Whether the Plustek SecureScan X50 can be integrated directly into the application. 4. Your estimated fixed price. 5. Estimated complete

Hi — Elias here from Miami. I understand the priority here is speed and simplicity for staff: create the purchase invoice, scan ID, save everything under the same transaction number, print, and move straight to the next customer. What usually matters most here is preventing duplicate invoice numbers, accidental overwrites, and scanner/file handling issues. I’d build this as a lightweight Windows 11 desktop app using C#/.NET with local encrypted storage, automatic PDF generation, printer support, and simple transaction search/reprint. For the scanner, the Plustek SecureScan X50 is suitable for Windows 11 and Plustek provides SDK support for integrating the SecureScan series into custom applications. I’ve worked with scanner/device integrations and would connect each capture directly to the active invoice number. Estimated fixed price: $2,000–$3,000 Timeline: 2–3 weeks, including installation and testing. A few questions to better understand the scope: Q1 – Will this run on one PC only, or could multiple PCs create invoices later? Q2 – Should scanned IDs be stored as images, PDFs, or both? Q3 – Do you already have an invoice layout/logo to follow? Full source code and setup instructions would be included. Looking forward to hearing from you.

Hi, I like the simplicity of this project. Staff should be able to enter the purchase details, scan the seller’s ID, and click Save & Print-without naming files or managing folders. I’d build the Windows application in Python with PySide6, using SQLite for sequential invoice numbers and quick searches. Each transaction would automatically create a PDF invoice and store its ID scan under the same number. Staff could find and reprint previous invoices, while completed records would be protected from accidental changes. I’ve worked on similar desktop software involving external equipment, document handling, and simple workflows for staff. I’d be happy to show you a relevant example and walk you through how I’d design your invoice screen. The Plustek SecureScan X50 looks promising: Plustek provides Windows drivers and SDK options. I haven’t integrated that exact model before, so I’d verify its SDK and test it with the scanner before promising a particular connection method. My estimated fixed price is £500, with delivery in 1–2 weeks once the scanner and printer are available for testing. That includes installation help, the full source code, and basic instructions. Any scanner SDK licence or hardware cost would be confirmed separately before we start. I’m ready to discuss the workflow and show you the similar work I’ve done.

Hi, I can create a simple Windows desktop application for your scrap metal business. I will use C# with Windows Forms for the application, ensuring a user-friendly interface. The application will automatically generate invoice numbers using a sequential logic. Each invoice will include fields for date/time, seller's name, address, description of goods, amount paid, and vehicle registration. For ID scanning, I will integrate the Plustek SecureScan X50 scanner using its SDK, allowing scanned IDs to be automatically associated with the corresponding invoice number. The application will save invoices as PDFs and scanned IDs as images or PDFs in a designated folder. To ensure simplicity, I will limit the main screen to essential buttons like SCAN ID, SAVE & PRINT, and NEW TRANSACTION. I will implement secure local storage for records and provide backup recommendations to prevent accidental data loss. I will also assist with installation and configuration, and provide full source code along with basic usage instructions. To get started, I will need access to the scanner for integration testing and any specific design preferences you may have. Thanks!

Hi, I can build this as a focused Windows desktop application with a very simple staff workflow, automatic sequential transaction numbering, PDF invoice generation, printing, ID scanning, and secure record retrieval. I’d use C#/.NET with a local SQLite database and Windows file storage, keeping invoice and ID records linked by the transaction number and preventing accidental overwrites through controlled permissions and immutable completed records. For scanner integration, I can work through TWAIN/WIA or the manufacturer SDK/API depending on the device; the Plustek SecureScan X50 should be assessed against its available Windows integration interface before finalizing the scanner implementation. I’ll also provide installation/configuration assistance, backup/recovery guidance, source code, and basic maintenance documentation. For a complete fixed-price quotation, I would first need to confirm the exact scanner interface and invoice layout rather than inventing a price before validating the hardware integration. Question 1: Will the Plustek SecureScan X50 be available for testing during development, and can you provide its exact model/SDK or Windows driver documentation? Question 2: Should the application store all records on the local PC only, or do you want an automatic encrypted backup to a second drive/NAS/cloud location as part of the solution? Regards, Houssame.

Hi there! Your project focuses on creating a fast, intuitive Windows application for generating purchase invoices and securely scanning/associating seller IDs for scrap metal transactions. I understand the need for simplicity, automatic file handling, and staff-friendly design. I have extensive experience developing Windows desktop apps with integrated scanning (TWAIN/WIA/SDK), PDF generation, and secure local storage. I’ve previously integrated document and passport scanners, including Plustek models, and can confirm the SecureScan X50 is suitable for direct integration using its SDK. My proposed approach: a streamlined desktop app built with .NET (C#), featuring a single main screen for invoice entry, SCAN ID, and SAVE & PRINT. Each transaction will auto-generate sequential numbers, create a dedicated folder, save PDF invoices, and associate scanned IDs automatically. Secure storage and retrieval, along with backup/recovery recommendations, will be provided. Would you prefer ID scans saved as PDF or image files (JPG/PNG)? Do you have any specific security/backup requirements or policies in mind? Best Regards, George
