Invoice & Document Automation

AI Invoice Processing for Accountants

Rima extracts vendor names, invoice numbers, line items, and amounts from PDFs automatically — with 99.9% accuracy, GL coding suggestions, and a full audit trail.

What is AI invoice processing?

AI invoice processing uses machine learning and optical character recognition (OCR) to automatically read financial documents and extract structured data — vendor name, invoice number, date, PO reference, line items, amounts, and tax — without manual data entry. The extracted data is validated against your rules, coded to GL accounts, and written to Excel or your accounting system.

Rima's financial document automation is built specifically for accounting teams. Instead of a generic OCR tool, Rima uses Blueprint templates — extraction rules you define once and reuse — so every invoice from a given vendor is processed the same way, every time.

How AI invoice and financial document extraction works

  1. Upload documents. Drop PDF invoices, scanned documents, or image files into Rima — individually or in bulk. The Rima Excel add-in also lets you trigger extractions directly from a spreadsheet.
  2. Apply a Blueprint template. Each Blueprint defines which fields to extract, how to validate them (e.g. amount must be positive, date must be within 90 days), and how to map extracted values to your Excel columns or chart of accounts.
  3. Review extractions and approve. High-confidence extractions are queued for bulk approval. Low-confidence items — new vendors, unusual layouts, missing required fields — are flagged with the specific issue highlighted for accountant review.
  4. Export or post. Approved data exports to Excel, CSV, or directly to your accounting system. Every extraction is logged with the source document, extracted values, confidence score, and approver.

What Rima extracts from invoices and financial documents

Rima's AI invoice and financial document extraction handles all standard invoice fields and adapts to non-standard layouts:

  • Vendor name, address, and tax ID
  • Invoice number, PO number, and reference codes
  • Invoice date, due date, and payment terms
  • Line item descriptions, quantities, unit prices, and extended amounts
  • Subtotal, tax amount, tax rate, and invoice total
  • Bank account details for payment processing
  • Currency and exchange rate where applicable

GL coding and accounts payable automation

Manual GL coding is one of the most time-consuming parts of invoice processing. Rima learns from your historical transaction data and vendor coding history, then suggests GL account codes, cost centres, departments, and tax treatments for each line item. Suggestions are always presented for accountant review — never applied automatically — maintaining the control that compliance requires.

For high-volume AP workflows, Rima can route invoices through an approval chain based on amount thresholds, vendor type, or GL account, with every approval logged to the audit trail.

Who uses Rima for AI invoice processing?

  • CPA firms and outsourced accounting providers — process invoices across multiple clients using saved Blueprint templates per client
  • AP teams at mid-market businesses — handle high volumes of vendor invoices without growing headcount
  • Controllers and accounting managers — accelerate month-end close by eliminating invoice backlog
  • Finance teams at PE-backed companies — standardize invoice processing across portfolio companies

Security and compliance for financial document automation

Invoice data contains sensitive vendor information, payment details, and financial figures. Rima's financial document automation platform is built with security at the core:

  • Data encrypted in transit (TLS 1.3) and at rest (AES-256)
  • Role-based access controls — staff see only their assigned client queues
  • Complete audit log of every extraction, coding suggestion, review, approval, and override
  • Source document retention linked to each extracted record
  • Exportable workpapers for client delivery and auditor review

AI Invoice Processing: Frequently Asked Questions

What is AI invoice processing?
AI invoice processing is the use of machine learning and OCR to automatically extract structured data — vendor name, invoice number, date, line items, amounts, and tax — from PDF or scanned invoices. The extracted data is then validated, coded to GL accounts, and written to your accounting system or Excel workpaper, eliminating manual data entry.
How accurate is AI invoice and financial document extraction?
Accuracy depends on document quality and configuration. Rima achieves 99.9% extraction accuracy on well-structured invoices using Blueprint templates that define exactly which fields to extract and how to validate them. For non-standard or handwritten documents, Rima routes items to a human review queue rather than guessing.
What file types does AI invoice processing support?
Rima processes PDF invoices (both digital and scanned), Excel-based invoice formats, and image files (JPG, PNG, TIFF). Multi-page documents, invoices with line-item tables, and documents containing multiple invoices are all supported.
Can AI invoice processing suggest GL account codes automatically?
Yes. Rima learns coding patterns from your historical transactions and vendor history, then suggests GL account codes, cost centres, and tax treatments for each invoice line. Suggestions are presented for accountant review and approval — not applied automatically — to maintain control and compliance.
How does AI financial document automation handle exceptions?
Rima uses a human-in-the-loop model. High-confidence extractions are queued for one-click approval. Items below the confidence threshold — new vendors, unusual formats, missing fields — are flagged for manual review with the specific issue highlighted. Every exception and override is logged in the audit trail.
Is AI invoice processing suitable for CPA firms with multiple clients?
Yes. Rima's Blueprint system lets CPA firms create and save extraction templates per client or vendor type, then reuse them across engagements. Each client's data is isolated, and the audit log tracks every extraction, review, and approval by user and date.
How does AI invoice processing integrate with accounting systems?
Rima exports structured data to Excel, CSV, and direct API connections to QuickBooks, Xero, NetSuite, and Sage on Teams and Enterprise plans. The Excel add-in lets accountants review and approve extractions directly inside the spreadsheets they already work in.
What accounting teams say

"We were manually keying 200+ invoices a month. Rima cut that to under 20 minutes of review — we went from 8 minutes per invoice to under 30 seconds, and errors dropped to zero."

AP Manager · Multi-location restaurant group, 300 employees

"We manage AP for 15 clients. Rima's Blueprint templates mean we set up extraction rules once per client and reuse them every month. It's saved us at least 2 full days of work per close cycle."

Engagement Manager · Outsourced accounting firm, 15 clients

"Our auditors asked for the GL coding rationale on 40 invoices. I pulled the full extraction log from Rima in 3 minutes — source document, extracted fields, GL suggestion, and who approved it. That used to take half a day."

Controller · SaaS company, Series B, 80 employees
