Manual invoice processing is expensive and error-prone. The average company spends $12--$15 to process a single invoice manually. AP teams touch every invoice 3–4 times before it's paid. Errors in data entry cause late payments, vendor disputes, and compliance issues.
We build automated invoice processing systems that read invoices, extract data, validate against purchase orders and contracts, and route for approval, with no manual data entry required.
AI OCR that reads invoices in any format, PDF, email, scan, or EDI
Automatic matching against POs, contracts, and GL codes
Approval workflow routing with exception handling for mismatches
We've built OCR and document automation systems for industrial and enterprise use

If your AP team processes 500 invoices a month at $12 per invoice, you're spending $6,000 a month on invoice processing. That's $72,000 a year. The industry benchmark for automated processing cost is $1--$3 per invoice.
At 500 invoices a month, automation saves $4,500--$5,500 per month. An automation system that costs $50,000 to build pays for itself in 9–12 months. Every month after that is margin.
The math gets better at scale. At 2,000 invoices a month, the savings are $18,000--$22,000 per month.

Capabilities
Invoices arrive via email, supplier portal, EDI, API, or upload. The system captures them from all channels, deduplicates, and queues for processing. No manual collection step. Invoices are in the system the moment they arrive.
We built an AI OCR system for gas station fuel delivery invoices that automated what was previously a fully manual data entry process. The same technology applies to any invoice format, structured or unstructured, digital or scanned. Header data and line items extracted and validated automatically.
Three-way matching: extracted invoice data checked against purchase orders, receiving records, and contract terms. Quantity, price, and vendor all verified automatically. Matched invoices post to the ERP. Mismatches get flagged with specific discrepancy details.
Exception invoices routed to the right approver based on your rules, by amount, by cost centre, by vendor, by department. Approvers get a notification with all the context they need to approve or reject. Approval is logged with timestamp and user ID for audit.
Approved invoices posted to your ERP automatically, AP record created, GL coding applied, payment terms calculated, and payment scheduled. No rekeying. No delay between approval and ERP entry.
Complete audit trail for every invoice: when it arrived, what was extracted, what matched, who approved, when it was posted. Month-end reporting on processing volumes, exception rates, processing time, and supplier payment performance. The data your auditors and AP manager need.
Why us
The engineers who assess your invoice workflows also build the automation. No bait-and-switch, no offshore handoff after the contract is signed. The team you meet in week 1 ships in week 12.
We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.
Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin. Track record across AI, SaaS, mobile, automation, and enterprise platforms across healthcare, fintech, logistics, and hospitality.
GDPR, HIPAA, SOC 2 compliance requirements are scoped in week 1, not retrofitted before launch. We have shipped HIPAA-compliant systems for US healthcare clients and GDPR-compliant products for European markets.
Before we scope a build, we model the savings against your current invoice volume and processing cost. At 500 invoices per month, automation typically pays back a $50,000 build in 9 to 12 months. You see the math before signing anything.
Tell us your current invoice volume and the systems you use. We'll estimate the savings and scope the build.
Process
We audit your current invoice process, formats received, volume by supplier, error types, and current processing time per invoice. We model the ROI before we design anything. You get a clear picture of what automation saves and what it costs before you commit.

Volume measurement by channel (email, EDI, portal, scan)
Error type and frequency analysis
ROI model with straight-through processing rate estimate
We build the OCR and AI extraction pipeline for your invoice types. High-volume, consistent suppliers get vendor-specific templates for maximum accuracy. Variable or occasional suppliers go through LLM-based extraction. Confidence scoring is built in from the start.

Confidence scoring and low-confidence flagging
We configure the three-way matching logic for your business rules, price tolerance, PO matching fields, approved vendor list, and duplicate detection. Exception routing rules are built to match your actual approval policy, not a generic workflow.

Duplicate invoice detection
We connect the automation system to your ERP, posting approved invoices as AP records, applying GL coding, and scheduling payment. Integration is tested against your actual ERP environment with real invoice data before go-live.

Payment terms calculation and scheduling
End-to-end testing with real invoice samples
We run the system in parallel with your manual process for the first two weeks, comparing outputs and tuning extraction rules. Once the straight-through rate meets the target, we cut over to fully automated processing. You get a dashboard showing volume, exceptions, and cost per invoice.

OCR Development

Automated invoice processing works in four stages: (1) Capture, invoices arrive via email, supplier portal, EDI, or scan. The system receives them and queues them for processing. (2) Extraction, AI OCR reads the invoice and extracts structured data: vendor name, invoice number, date, line items, amounts, tax, and totals. (3) Validation, the extracted data is matched against your PO, contract, or approved vendor list. Discrepancies are flagged for exception handling. (4) Routing, matched invoices are posted to your ERP automatically. Exceptions go to the right approver with context.
For clean, well-formatted invoices from known vendors, AI extraction accuracy is 95–99%. The harder cases are handwritten invoices, poor-quality scans, and non-standard formats from occasional vendors. We handle these through a combination of AI confidence scoring (low-confidence extractions are flagged for human review), vendor templates (we build specific extraction rules for your highest-volume suppliers), and continuous learning (corrections feed back into the model). In production, most systems reach a straight-through processing rate of 80–90%, meaning only 10–20% of invoices require any human touch.
PDF invoices (both digital and scanned), image files (JPG, PNG, TIFF), email body invoices, XML and EDI structured formats, and Excel or CSV invoices from certain suppliers. The extraction approach differs by format, structured formats like EDI are parsed directly, unstructured formats like scanned PDFs go through OCR. We build a unified data model at the output so your downstream systems get consistent data regardless of how the invoice arrived.
Yes. We've built integrations with SAP, Oracle, Microsoft Dynamics, NetSuite, Xero, QuickBooks, and Sage. The integration posts validated invoice data and creates the payable record automatically. For ERPs with well-documented APIs, integration is straightforward. For older ERPs with limited APIs, we use file-based exchange or a direct database connector. We scope the integration requirements during discovery.
Exceptions are a normal part of invoice processing. The system flags them (price mismatch, missing PO, duplicate invoice number, vendor not in approved list) and routes them to the right person with context, what was extracted, what was expected, and what action is required. Approvers resolve exceptions in a web interface without touching the underlying data. The resolution is logged for audit. We tune the exception rules to match your actual approval policy.
A focused invoice automation system covering email ingestion, AI extraction, PO matching, approval routing, and ERP integration typically runs $30,000 to $70,000. Cost depends on the number of invoice formats, matching rule complexity, and ERP integrations required. For AP departments processing 1,000+ invoices per month, ROI is typically positive within 6 months. We calculate expected savings based on your current volume and processing cost before scoping the project.
