When to Choose Each Platform

The right choice depends on your specific situation. Here are real-world scenarios and our honest recommendations.

Mid-Market Manufacturing (500 employees)

Needs: Process 10K invoices/POs monthly, integrate with NetSuite, AP team of 3, need results fast.

Recommendation: Kynthar
Setup in 1 day, Premium plan at $1,199/mo for 10K pages. Saves ~$4K/year vs Rossum + faster time-to-value. No long-term contract required.

Fortune 500 Enterprise (50K employees)

Needs: Process 500K documents/year across 12 departments, complex routing rules, SAP integration, ISO compliance, 99.9% SLA.

Recommendation: Rossum
Enterprise workflow engine handles multi-stage approvals. Certified SAP integration reduces risk. Dedicated support critical at this scale. Worth the premium.

Professional Services Firm (50 employees)

Needs: Process client invoices, receipts, contracts. Need full-text search ("find all Acme Corp contracts"). Budget-conscious.

Recommendation: Kynthar
Email ingestion perfect for ad-hoc documents. Semantic search is killer feature ("show contracts expiring Q2"). $249/mo vs $18K/year is no-brainer.

Healthcare System (Multi-Site)

Needs: HIPAA compliance, process insurance claims + invoices, integrate with Epic, need BAA, 24/7 support.

Recommendation: Rossum
HIPAA-ready environments with BAAs available now. 24/7 phone support critical for healthcare. Mature compliance posture reduces audit risk. (Kynthar SOC 2 coming Q3 2025.)
