Join hundreds of teams growing faster by automating the busywork with Lido.
AP automation spans invoice extraction, approval workflows, payment processing, and full procure-to-pay platforms.
Extraction vs. workflow. Lido provides the highest accuracy invoice extraction. BILL, Stampli, and others provide end-to-end AP workflow. Choose based on whether your bottleneck is data accuracy or process automation.
Company size. BILL and Ramp suit SMBs. Stampli, AvidXchange, and Yooz target mid-market. Tipalti, Medius, and Basware serve enterprises.
Payments. BILL, Tipalti, and AvidXchange include payment processing. Lido and Stampli focus on invoice processing.
Budget. Lido and Ramp offer free tiers. BILL starts at $45/month. Everything else requires custom pricing.
Now that you know the strengths of each tool, you can choose the one that fits your AP workflow.
AP automation software handles part or all of the accounts payable process: receiving invoices, extracting data, routing approvals, matching to purchase orders, and executing payment. Some tools cover the full cycle (BILL, Tipalti). Others specialize in one step like data extraction (Lido) or payment execution. The goal is reducing manual data entry, speeding up approvals, and cutting errors that cause duplicate payments or missed early-pay discounts. For a deeper explanation, see our guide on what accounts payable automation is and how it works.
For small teams (under 500 invoices/month), $29-$300/month with self-serve setup. Mid-market companies (500-5,000 invoices/month) typically pay $500-$5,000/month with guided implementation. Enterprise deployments (5,000+ invoices/month) range from $5,000 to $50,000+/month with professional services and 3-12 month implementation timelines. Hidden costs include per-transaction fees, per-user pricing that scales with team size, and implementation fees that can equal 1-2x the annual subscription.
Yes. Most AP automation tools integrate with QuickBooks, NetSuite, Sage, and Microsoft Dynamics. BILL has the strongest QuickBooks integration. Tipalti and Stampli are strongest with NetSuite and Sage Intacct. For SAP environments, Concur, Basware, and Medius offer native integrations. Extraction tools like Lido output structured data that feeds into any ERP via spreadsheet import, API, or direct integration. See our ERP integration tools guide for specific setup steps.
Invoice OCR is one step within AP automation. OCR reads invoice documents and extracts structured data: vendor name, amounts, line items, dates. AP automation is the broader workflow: receiving invoices, extracting data, routing approvals, matching to POs, and executing payment. You can use OCR tools like Lido without a full AP platform, or use a full AP platform with its built-in OCR. Many teams use dedicated OCR for accuracy and a separate platform for workflow.
Self-serve tools (Lido, BILL, Ramp) can be running in hours to days. Mid-market platforms (Stampli, Yooz, AvidXchange) typically take 2-6 weeks with guided implementation. Enterprise platforms (Basware, Coupa, Medius) take 3-12 months due to complex ERP integrations, custom approval hierarchies, and change management. The biggest implementation variable isn't the software; it's internal alignment on approval policies and GL coding standards.
Yes, if you process more than 50 invoices per month. At 15 minutes per invoice for manual processing, 50 invoices costs about 12.5 hours of labor monthly. At $30/hour, that's $375/month in processing time, not counting errors, late payment fees, or missed early-pay discounts. Tools like Lido ($29/month) or Ramp (free) automate the most time-consuming steps at a fraction of that cost. Below 50 invoices/month, setup time probably doesn't justify the investment.
Strong extraction tools hit 95-99%+ accuracy on structured fields (vendor name, invoice number, total amount, date). Accuracy drops on complex elements like line items, nested tables, handwritten notes, and poor-quality scans. Template-free tools like Lido maintain consistent accuracy across formats because they don't depend on layout-specific rules. Template-based tools can achieve higher accuracy on trained formats but fail on new or changed layouts. Always test on your actual invoices. Demo accuracy numbers are meaningless.
