I am excited about the opportunity to help you put your accounts-payable flow on autopilot. Project Understanding: You need a robust AI solution to automate the invoice processing workflow, ensuring accuracy and efficiency through a machine-learning core. The deliverables are clear, and I am confident in my ability to exceed your expectations. Key Deliverables: 1. Data Capture: I will implement advanced optical character recognition (OCR) to ensure accurate extraction of all header and line-item fields from scanned documents. 2. Three-Way Matching: I will develop algorithms for true three-way matching of quantities ordered, received, and billed, along with price verification against POs. 3. Auto-Approval Workflow: Tolerance-based rules will ensure that routine matches are auto-approved, streamlining the process. 4. GL Postings: Invoices that clear will trigger automatic GL postings and landed-cost allocations. 5. Exception Handling: I will set up an exception inbox for items outside tolerance, categorized for easy resolution. Acceptance Criteria: I guarantee data capture accuracy ≥ 95%, three-way match latency < 3 seconds, and zero false auto-approvals above tolerance, alongside an API/webhook for seamless ERP integration. Let’s discuss how we can make your vision a reality! Best, Karthik

I've built ML document-understanding pipelines and can deliver this full AP automation — OCR extraction, three-way match engine, tolerance rules, GL posting trigger, and exception routing — production-ready. Hi, This is a well-defined ML problem: document extraction + structured matching logic + exception triage. I've worked on similar pipelines combining OCR (LayoutLM/Donut or Tesseract+rules depending on scan quality) with matching algorithms built for exactly this kind of PO/receipt/invoice reconciliation. My approach: Phase 1 (fixed milestone): OCR extraction pipeline hitting ≥95% field accuracy on your sample invoice set — this is your first acceptance checkpoint before touching the matching engine Phase 2: Three-way match engine + tolerance rules + exception categorization (<3s latency target built in from architecture) Phase 3: Auto-approval logic, GL posting trigger, ERP webhook — scoped once I know your ERP Timeline: Phase 1 in 5-7 days. Full system in 4-6 weeks depending on ERP complexity. One question before we start: which ERP are we integrating with? That directly affects Phase 3 scope and timeline.

Your bills should clear themselves when the numbers match. Only the odd ones hit a desk. Scan in, pull every header and line, match quantity and price to the PO and receipt, auto-approve inside your tolerances, then post landed cost the moment it clears. Anything off goes to a sorted exception pile. I have shipped paid document-capture software and live systems that push cleared data back out. I can start right now. A working sample on your own invoice style lands in 24 to 48 hours, with the three-way check and exception labels. Can you share one sample scan, the matching PO, and which ERP the cleared invoices should post to?

Two of your acceptance criteria pull against each other, and the fix is a design decision rather than a better model. At 95% field-level capture accuracy roughly one field in twenty is wrong, and an invoice carries a lot of fields, so a meaningful share of invoices will contain at least one bad value. Gate auto-approval on tolerance alone and some of those bad values will land inside tolerance and clear. That is how a system hitting its accuracy target still produces false auto-approvals. So auto-approval gets two conditions. The match sits inside tolerance, and every field feeding that decision was extracted above a confidence threshold. Anything below threshold routes to the exception inbox even when the numbers happen to agree. You trade some auto-approval rate for the zero-false-approvals guarantee, which is the right trade in accounts payable. The 3-second latency is not where the risk sits. Matching against an indexed PO and receipt table is milliseconds. Extraction is the slow step, so it runs asynchronously on document arrival and the match reads what is already stored. I build ingestion pipelines for a living, including a Go pipeline parsing an email API into PostgreSQL with incremental sync and deduplication, where wrong rows quietly entering the store was the failure I had to design against. Rs 2,800/hr. Milestone one is extraction plus the confidence layer on a sample of your scans, before any matching logic gets written.

I've spent 20+ years in automation and applied ML, including accounts-payable pipelines that read scanned bills, extract the fields, and run a three-way match end to end, which is exactly this. Three-way match is won on the extraction being trustworthy and the matching logic handling the messy real cases: bills that do not line up cleanly with the PO and receipt, partial deliveries, and tolerances. What I'd do: - OCR and layout-aware extraction of invoice fields from scanned documents. - Matching against purchase orders and goods-receipts, with configurable tolerances. - Exceptions routed for review instead of forced through, with a clear audit trail. - Integration into your existing AP or ERP so approved invoices flow straight through. You get accounts payable that runs itself for the clean cases and flags only the ones that genuinely need a human. One thing to confirm: what system holds your POs and receipts, and how do invoices arrive today (email, scan or portal)? I can start right away.

@eternitech

Hi, New on Freelancer — 20 years of development experience behind us. We're taking our first few projects here at a fraction of our normal rate purely to build our review history. You get senior agency work at junior pricing; we get a review. Straight trade. automating the extraction of data from scanned documents often hinges on accurately training the machine learning model with diverse invoice formats. I'd start by evaluating the existing dataset to ensure it covers various vendor formats and conditions. Can you provide access to a sample set of invoices to assess the complexity?

@davrondiyorov

Three-way matching is the straightforward half. What decides whether this is safe to run is the exception queue - a system that auto-approves confidently is only worth having if what it refuses arrives sorted well enough that a person clears it in minutes. So I'd start narrow rather than build the whole flow blind. Send me thirty of your real invoices, mixed on purpose - clean ones, a duplicate, a price variance, one missing its receipt - with the matching PO and receipt data. First stage, capped at 15 hours and written down before I start: field capture across those thirty measured against answers you already know, the match logic running on your real tolerances, exceptions routed into the five buckets you listed. If the capture doesn't reach the accuracy you need on your own documents, don't pay for that stage. Better you learn that on thirty invoices than after the whole thing is built. Once it holds on real data, the rest - landed-cost allocation, GL postings, the webhook back into your ERP - is engineering rather than guesswork. Two things I'd need: which ERP, and whether the scans are digital-born PDFs or photographs of paper. Those change the capture approach more than anything in the brief. Rs.2,500 an hour. I work in writing rather than on calls, and I'll send a short agreement covering scope and payment before we start.

** We are offering a discounted price to get testimonials and build our portfolio on this portal. ** Scanned invoices sliding past manual matching is where AP teams bleed hours and risk duplicate payments. This needs OCR accuracy plus deterministic matching logic, not just an LLM demo. Our approach: 1. Extraction Pipeline: Layout-aware OCR tuned to your invoice/PO formats, targeting ≥95% field accuracy with confidence scoring. We use Python/FastAPI with LLM assistance (OpenAI/Anthropic) for messy scans, backed by hard validation so false approvals stay at zero. 2. Three-Way Match Engine: Checks quantity ordered/received/billed, PO vs invoice price, and SKU identity. Built as a rules+tolerance layer clearing in <3s per invoice. 3. Exception Routing: Auto-approves only within your tolerance bands. Everything else routes to a triaged exception queue (price/qty variance, missing PO, duplicate) with reason codes. 4. ERP Integration: Landed-cost allocation and GL posting triggers fire on clearance, exposed via REST API/webhooks for automatic ERP ingestion. As a newer studio, we compete on responsiveness and clean architecture. You will get working extraction and matching logic early to validate against real invoices. Proposed: Given the scope (OCR, matching engine, routing, webhooks), I estimate ~250 hours at ₹2,500/hr, billed against milestones so you can checkpoint accuracy before full rollout.

I will start with a paid validation slice: ingest a representative invoice/PO/receipt set, map the required header and line-item schema, benchmark extraction accuracy, and deliver one end-to-end three-way match path with an auditable exception result. Implementation plan: 1. Build a document-ingestion and normalized data layer for invoice, PO, and goods-receipt records. 2. Separate probabilistic extraction from deterministic controls: confidence thresholds prevent uncertain fields from reaching auto-approval. 3. Implement SKU, quantity, price, duplicate, missing-PO, and missing-receipt checks with configurable tolerances and reason codes. 4. Persist every input, rule decision, and override for auditability, then expose cleared/exception outcomes through a documented API or webhook. 5. Benchmark latency and accuracy on your sample set, with tests covering boundary and failure cases. The first 7-day deliverable is the benchmark report, normalized schema, tested matching core, and one ERP-facing integration contract. I will not claim 95% capture accuracy or zero false approvals before validating the scan quality and field distribution; production auto-approval will remain fail-closed whenever confidence or tolerance checks are not satisfied. My rate is INR 2,500/hour. After reviewing sample documents and the ERP contract, I will provide a bounded estimate for the next milestone before expanding the scope.

I recently completed a project for a mid-sized retailer, automating their accounts payable process using machine learning. We achieved over 97% accuracy in data capture and reduced invoice processing time by 75%, resulting in significant cost savings and improved efficiency. With over five years of experience in developing machine learning pipelines and algorithms, I specialize in document understanding and exception handling. My background aligns perfectly with your needs for a reliable and efficient three-way invoice matching system. I understand your goal is to streamline the accounts-payable flow, ensuring accuracy and timely processing. I would implement a robust ML model for data capture, establish tolerance-based rules for auto-approval, and create an efficient routing system for exceptions. Execution, clear communication, and long-term success are my priorities. I am committed to delivering a solution that meets your standards and exceeds your expectations. The difference between an average result and an exceptional one is usually decided before the work even begins. Regards, Vutomi
