@SEOGlobalLLC

Hi there, thanks for the detailed explanation. I understand you need an automated solution to scan hundreds of PDF invoices, accurately extract vehicle card number, litres dispensed, and exact date-time, then detect and report duplicate invoices based solely on those fields rather than invoice numbers. SEO Global Team has strong experience building reliable Python-based document processing pipelines using PDF parsing and OCR, structured data extraction, and pandas-based comparison logic to flag duplicates with confidence scoring and clear audit trails. Our approach is to implement a re-runnable script that automatically processes all PDFs in a folder, intelligently extracts and validates the target fields, groups suspected duplicates, and exports a clean CSV or Excel report with references and confidence indicators, supported by well-documented code and a concise README. Are the PDFs mostly text-based, or do some require full OCR processing? Do the invoices follow a consistent layout or are there multiple templates? Should the script flag near-matches (for example, small timestamp differences) or only exact matches?

@amgadmourad18

Hello , I'm a Data Science expert , ready to work on your project and i have done similar projects related to reading and analyzing the pdf s before so i'm comfortable to work on your task . message me so we can move forward . thanks

@Techroj

Dear Client, Greetings!! I have gone through the project description, and found that all of the mentioned requirements fall over my expertise, as I have hands-on experience on python, AI/ML, Data Science, software building, etc. I can build a Python-based pipeline that scans all PDFs end to end, reliably extracts the vehicle card number, litres, and tanking timestamp, then groups and flags true duplicates with a confidence score. I’ve done similar invoice and document-matching work using pdfplumber, OCR fallback, and pandas, and I’ll deliver clean CSV or excel output plus reusable, well-documented code so you can rerun it on future batches with almost no setup. Lets discuss further over a chat. Also, I have been coding on Machine Learning and Data Science with python from past 7 years. I have the experience of working with 4 giant tech companies, including freelancing on upwork, fiverr and freelancer. Hope to hear from you soon!!. Regards, Rojan

@andriik18

Hi, I understand the importance of efficiently detecting duplicate invoices in your PDFs, and I'm confident I can deliver an automated solution tailored to your needs. Creating an AI-powered script that accurately extracts the vehicle card number, litres dispensed, and date-time will ensure you spot duplicates effectively without manual effort. With over 7 years of experience in software development, particularly in data extraction and processing, I have the technical skills needed for this project. My proficiency with Python, coupled with libraries like pdfplumber for PDF parsing and pandas for data logic, aligns perfectly with your objectives for accuracy and ease of rerunning processes. I will ensure that your invoices are processed, duplicates are detected, and results are clearly reported in a CSV format. Let’s discuss the timeline for implementation, and how I can tailor the solution to your workflow.

@ivicab6

Hi, I can build a reliable Python pipeline that processes your entire invoice folder automatically, extracts the vehicle card number, litres, and exact tanking date-time from each PDF (text-first parsing, with OCR fallback only when needed), then groups and flags suspected duplicates based strictly on those three fields. You’ll get a rerunnable command that outputs a clean CSV/Excel report with duplicate groups, confidence score, and PDF/page reference for spot-checking, plus well-commented code and a short README for easy future batches. Best Regards, Ivica

@mojjammil

Hello, I am immediately available to start. I have built OCR-based invoice parsers in Python (pdfplumber, PyPDF2, Tesseract) and used pandas for dedup reporting. I will process PDFs in a monitored folder, extract vehicle card number, litres, and date-time with high accuracy, group duplicates, and export a CSV with confidence scores and page references. Best regards, Mojjammil

@huonghy89

Hi, I hope you are doing well. Very happy to bid your project because my skills are fitted in your project. I’ve built multiple Python document-ingestion pipelines that extract structured fields from mixed (text + scanned) PDFs using pdfplumber/PyMuPDF + OCR, then validate and deduplicate records with robust matching logic and reviewable reports. I will deliver a rerunnable Python script (and optional lightweight UI) that batch-scans your invoice folder, extracts vehicle card number, litres, and exact tanking date-time using hybrid text parsing + high-accuracy OCR fallback, and writes per-PDF results with page references and extraction confidence. I will then implement deterministic duplicate grouping (exact match on the three fields, plus configurable tolerance rules if desired), exporting a clean CSV/Excel report that clusters suspected duplicates, includes confidence scores, and ships with well-commented code + a short README for easy future re-runs. If you send the message, we can discuss the project more. Thanks.

@EhtishamHaider1

As a versatile Electrical Engineer and seasoned Data Scientist, I believe my unique set of skills perfectly aligns with the challenges your project poses.

To ensure reliable accuracy from OCR, I also have hands-on experience with Tesseract and other similar tools. Moreover, my expertise in handling large datasets, generating reports and visualizations using Power BI, Tableau, Google Sheets and Excel complements the tabular-form output format you require for duplicates. Additionally, my overall proficiency in multiple programming languages enables me to adapt quickly to your tech stack preferences indefinitely. Coming equipped with such broad capabilities, I assure you that not only will I meet the acceptance criteria provided, but also establish a well-constructed foundation for your future iterations with little setup effort.

@jonhw5

Hello, thanks for posting this project. I've carefully read your requirements and believe this is an excellent fit for my skill set. I have significant experience automating PDF data extraction and duplicate detection using Python tools such as pdfplumber, PyPDF2, and Tesseract OCR, along with pandas for robust comparison logic. I can deliver a lightweight script that processes all PDFs in bulk, extracts the needed fields with high accuracy, and outputs clear CSV/Excel reports of suspected duplicates, complete with confidence scores and page references. The solution will be easy to re-run for future invoice batches, well-documented, and straightforward to set up. To ensure at least 95% extraction accuracy and minimize false positives, may I ask if the three target fields (vehicle card number, litres dispensed, date-time) consistently appear in similar locations/formats across your invoices, or do they vary based on invoice template or supplier? Looking forward to hearing from you. Warm regards, Vitalii.
