How it works

StartOS connects natively to 25+ tools across payments, banking, cloud infrastructure, AI providers, payroll, CRM, timesheets, tax, AP payments, and corporate cards. Data syncs automatically and posts to your GL.

  • Stripe: subscription + invoice + payment sync with webhook receiver
  • Plaid: automated bank feed with incremental transaction sync
  • AWS, GCP, Azure, Snowflake: cloud cost import (API + CSV)
  • OpenAI, Anthropic, AWS Bedrock, Vertex AI: AI compute cost sync
  • QuickBooks, Xero: full transaction-level migration, not just opening balances
  • Gusto, Rippling: employee + payroll sync with GL posting (US + global)
  • HubSpot, Salesforce: CRM pipeline sync for forecasting
  • Toggl, Harvest: timesheet sync for capitalization + services billing
  • Ramp, Brex: corporate card transaction sync
  • Mercury, Bill.com, Ramp Bill Pay: AP payment execution
  • Carta: cap table migration (multi-file import)
  • Track1099, Tax1099: 1099-NEC e-filing
  • Anrok, Avalara: automated sales tax calculation

2

Data syncs automatically

Transactions, costs, and subscriptions flow in on schedule. Dedup prevents duplicates.

3

Posts to your GL
