Frequently Asked Questions (FAQs)

Which CRM is best for a mid-sized US marketing agency?

For most mid-sized agencies, HubSpot is the superior choice because it integrates marketing, sales, and content management into a single, user-friendly platform. It allows agencies to track the entire client journey from the first ad click to the final signed contract, providing the clear ROI reports that US clients demand.

How does Deel protect my company from legal risks when hiring abroad?

Deel acts as a "legal shield." When you use their EOR service, Deel becomes the legal employer of record in that country. They handle all the local compliance, tax filings, and insurance requirements, meaning that if there is a legal dispute, Deel is the entity responsible, protecting your US business from direct liability.

Is Microsoft 365 really worth the cost compared to free alternatives?

Yes, primarily because of the "Copilot" AI and enterprise security. While free tools exist, they do not offer the same level of deep integration, automated compliance, and professional-grade security that US corporations require to protect their data and maintain a consistent workflow across thousands of employees.

How can I lower my monthly Snowflake costs?

The best way to lower costs in Snowflake is to optimize your "Virtual Warehouses." By using auto-suspend and auto-resume features, you ensure that you are only paying for compute power when queries are actually running. Additionally, organizing your data into "clustering keys" can significantly reduce the amount of data scanned, making queries faster and cheaper.

What is the difference between Gusto and Dell for a US company?

Gusto is designed primarily for employees and contractors based within the United States, focusing on US state and federal compliance. Deel is designed for global hiring, allowing you to hire and pay workers in 150+ countries. Many US companies use both Gusto for their domestic team and Deel for their international remote talent.
