The fastest way to rename hundreds of invoices by vendor name and date is AI-powered extraction — processing 1,000+ invoices in under 3 minutes with 95%+ accuracy.

Connect your invoice folder (Google Drive, Dropbox, or local upload) — AI processes files as they arrive.
AI extracts vendor name, invoice date, invoice number, and amount from every document using OCR + NLP.
Preview all suggested filenames (e.g., 2026-03-15_Acme_Corp_INV-4521_$2,450.pdf), then apply the entire batch.

Accounting teams process 1,200+ invoices in under 3 minutes. Saves 80+ hours per year vs manual renaming.

The challenge

The problem every AP team knows

Manual invoice renaming is tedious, error-prone, and unsustainable at scale.

Monthly close arrives and your shared drive fills with invoice_final_v2.pdf, scan001.pdf, and Document(3).pdf. Each file needs to be renamed with the vendor name, date, invoice number, and amount — and every one has to be opened individually.

Manual renaming: 2–3 minutes per file × 500 invoices = 16+ hours/month

Errors compound: wrong dates, misspelled vendors, missing invoice numbers

Reconciliation slows down when filenames don’t match your naming convention

Audit prep becomes a scavenger hunt across inconsistently named folders

The real cost of manual renaming

2–3 minutes per invoice × 500 invoices = 16+ hours every monthspent on a task that adds zero value. That’s a full-time employee spending two entire workdays just renaming files.

AI-powered method

How it works

End-to-end automation from upload to renamed file. No scripting, no manual data entry.

Connect your invoice source

Link Google Drive, Dropbox, or upload directly. Set up a watched folder for automatic processing — new invoices are picked up as they arrive from vendors and clients.

Choose a naming template

Use pre-built accounting templates or create custom patterns. Save templates per client for reuse.

Let AI extract fields

OCR reads scanned invoices. AI identifies vendor name, date, invoice number, total amount, and currency — even on multi-page documents and varied layouts.

Review with confidence scores

Each rename shows extraction confidence. High-confidence files auto-approve. Low-confidence extractions are flagged for review with the source text highlighted.

Auto-approve thresholds

Set a confidence threshold (e.g. 90%) and invoices above it are renamed automatically. You only review the flagged ones — typically under 5% of the batch.

Apply batch

One click applies all renames. Originals are preserved alongside renamed copies. Full undo available at any time.

Ready-made patterns

Common naming templates for invoices

Start with a proven pattern or build your own. All templates support dynamic field extraction.

Standard invoicesNaming pattern

YYYY-MM-DD_{Vendor}_INV-{Number}.pdf

ResultClean, sortable format. Groups by date, identifies vendor and invoice number at a glance.

With amountsNaming pattern

YYYY-MM-DD_{Vendor}_INV-{Number}_${Amount}.pdf

ResultAdds dollar amount for quick reference during reconciliation. Ideal for AP teams.

Client-groupedNaming pattern

{Client}/YYYY-MM-DD_{Vendor}_INV-{Number}.pdf

ResultOrganizes into client subfolders automatically. Perfect for multi-client bookkeeping firms.

Tax-prep friendlyNaming pattern

YYYY_{Category}_{Vendor}_{Amount}.pdf

ResultGroups by year and expense category. Makes tax season prep straightforward.

Alternative approaches

Manual and semi-automated methods

If you prefer a hands-on approach or need to handle edge cases, these alternatives work — but come with trade-offs.

1. Manual renaming in Explorer/Finder

Right-click, rename, type. Functional for fewer than 10 files. No content extraction — you open each invoice and transcribe fields by hand.

2. PowerShell or Bash scripts

Can read file metadata (creation date, size) but cannot read invoice content without OCR libraries. Requires scripting knowledge and ongoing maintenance.

3. Adobe Acrobat Action Wizard

Supports text extraction via OCR, but building naming logic requires JavaScript scripting inside Acrobat. No built-in AI field extraction.

4. Python + OCR libraries (Tesseract)

Full control with pytesseract or pdf2image. Expect 8–12 hours to build a working pipeline. Ongoing maintenance as invoice layouts change. Accuracy depends heavily on scan quality.
