What SigniFlow is
SigniFlow is a document-signing service from SigniFlow, headquartered in Johannesburg, South Africa. It provides audit trails, document templates, bulk sending, API access, and SMS authentication. API is its listed platform, and signature order supports both options. The service uses a freemium model with a free plan. SignFree covers one user, 50 document storage per user, three workflows, three digitisation portfolios, and three free 2D FaceSign uses. Business Cloud lists 200 document storage per user. Larger plans increase capacity: Nano-50 supports up to 50 users, 6,000 API workflows, and 10,000 document storage; Micro-100 supports up to 100 users, 12,000 workflows, and 20,000 storage; Mega-250 supports up to 250 users, 18,000 workflows, and 50,000 storage; Terra-500 supports up to 500 users, 24,000 workflows, and 100,000 storage.
