What it is

Sanka Flow recreates legacy processes and coordinates operations across finance, sales, procurement, and HR. It can work alongside migrated systems or run independently: standalone use covers billing, sales documents, inventory, and purchasing. Sales tools include CRM, deals and opportunities, quotes, CPQ, incentives, customer service, and a customer portal. Finance functions span invoicing and accounts receivable, accounting, billing, subscriptions, revenue recognition, invoice processing, expenses, and monthly close. Procurement and HR cover purchase orders and payments, vendor and spend management, inventory, employee management, payroll, attendance, leave requests, reviews, and approval workflows. Claude can handle recurring back-office tasks using Flow records, pause at configured approvals, and leave a log on the record. It is available through ChatGPT, Claude, Slack, email, and Teams. Flow names HubSpot, Salesforce, Shopify, and Attio as platforms it works with, and also supports standalone or custom setups. The HubSpot workflow can take approved deals through documents, signatures, billing, accounting, purchasing, fulfillment, and automated workflows, with accounting-ready records synced to Xero or QuickBooks. The free plan is free; paid access starts at $99/mo.
