The Contractor Compliance Checklist Every SaaS Ops Team Needs

Compliance Gaps Are Invisible Until They Aren't

Almost nobody skips a compliance step on purpose. It happens because the company is moving fast and everything looks fine in the moment. A missing W-9 doesn't cause a problem until January, when you're trying to file 1099s and chasing a tax ID from someone you stopped working with months earlier. An IP clause that never got written doesn't matter until you're raising a round or selling the company, and suddenly a contractor from two years ago has a legitimate claim on code they wrote.

These gaps compound. A missing form leads to a filing penalty, the penalty surfaces in an audit, the audit turns up other gaps, and now you're spending real money and real time cleaning up something that would have taken ten minutes to do correctly the first time. Run this checklist before every new engagement, and again at the six-month mark for anything ongoing.

Before Work Starts

Legal

Contractor agreement signed by both parties, on file
Agreement assigns IP created during the engagement to your company, in writing
Non-solicitation language included
Agreement states the contractor covers their own taxes, benefits, and equipment
Termination terms are specific: notice period, grounds for immediate termination, final payment handling

Tax and Payment

W-9 collected for US-based contractors before the first payment
W-8BEN collected for international contractors, renewed every three years
Tax ID on file and checked for valid format
Currency and payment terms stated explicitly in the contract
Banking details stored in a secure system, never in an email thread

Classification Risk

Contractor has other clients, and you have some evidence of that
Contractor sets their own schedule; you define deliverables, not hours
Contractor uses their own core tools and equipment
Work sits outside your core product, which matters especially under California's ABC test
Engagement has a defined end point or scope, not an indefinite ongoing relationship

Gap	What It Costs	Fixable After the Fact?
1099 not filed (US)	$60 to $310 per form, plus possible backup withholding	Yes, file late with a penalty
W-8BEN missing	30% withholding exposure on past payments	Partially, collect now, past exposure remains
Misclassification finding	Back taxes, benefits, penalties, often $50k to $500k+	Very difficult, usually a legal dispute
IP never assigned	Contractor may retain rights to the work product	Difficult, needs their cooperation
Access not revoked at offboarding	Data exposure, incident risk	Immediate action needed

Ongoing, Every Quarter

Tool access still matches current scope, no leftover permissions from an earlier phase
Cloud IAM permissions reviewed for least privilege
Shared credentials rotated in the last 90 days
Contact information current
Insurance verified for anyone handling customer data or infrastructure access

Most overlooked item: IP assignment. Without an explicit written assignment, a contractor can retain copyright over what they built for you under US law. Work made for hire rules that automatically apply to employees do not automatically apply to contractors. Put it in writing every time.

When the Engagement Ends

Final timesheets reviewed and approved
Final invoice processed and payment confirmed
Every tool access revoked within 24 hours, no exceptions
Contractor removed from channels and distribution lists
Final 1099-NEC filed if a US contractor earned more than $600 in the year
Access and engagement record archived with an offboarding date
