Frequently asked questions

Can I skip contracts for friends?
Written terms still protect relationships when money is involved—scope and payment disputes happen with friends too.
What should a kickoff email include?
Timeline, deliverables, how to submit feedback, billing rhythm, and who approves work.
When do I request a W-9?
Before first payment or during vendor onboarding—earlier prevents AP delays.
How do I handle slow client inputs?
Reference SOW client responsibilities and document delays in writing for schedule adjustments.
Should onboarding include a questionnaire?
A short intake form captures goals, assets, and constraints before deep work begins.
What if the client rushes start date?
Do not skip signed scope for urgency—send a minimal SOW and deposit invoice first.
