SOC 1 for SaaS Companies
If your SaaS touches customer financials -- billing, invoicing, payment processing -- your enterprise customers' auditors will ask for a SOC 1.
When SaaS triggers SOC 1
The trigger isn’t being SaaS -- it’s affecting ICFR. Billing engines, subscription management, usage metering, and payment processing all feed your customers’ financial statements. If your platform calculates what customers owe or what their customers paid, you’re in scope.
Type 1 first, Type 2 next
The standard SaaS journey: a Type 1 to satisfy the first enterprise deals quickly (4–12 weeks), then a Type 2 observation period for the renewals that demand it. Don’t promise a Type 2 timeline you can’t hit -- the observation period is non-negotiable.
Scoping a multi-tenant platform
Define the system boundary tightly: the billing and transaction services in scope, the marketing site out. Shared infrastructure needs clear control allocation. Subservice organizations (your cloud provider, payment processor) need carve-out vs inclusive decisions before scoping -- not during fieldwork.
Realistic costs
SaaS Type 1: $10K–$30K planning estimate. First Type 2: $30K–75K all-in for a mid-market SaaS. Combined SOC 1 + SOC 2 programs -- which most SaaS companies need -- cost materially less than separate engagements. See the cost guide.
