Frequently Asked Questions

Is Gusto or ADP cheaper?

Gusto is generally cheaper and more transparent for small businesses. ADP requires custom quotes, which makes comparison harder, and add-on fees can accumulate. For straightforward payroll under 50 employees, Gusto typically wins on cost.

Does Gusto handle payroll taxes automatically?

Yes. Gusto automatically calculates, files, and pays federal, state, and local payroll taxes on your behalf. It also generates W-2s and 1099s at year-end. This is one of Gusto's key selling points for small business owners without payroll expertise.

Is ADP good for small businesses?

ADP RUN is designed for small businesses and works well. However, many small business owners find Gusto's interface simpler and its pricing more transparent. ADP becomes a clearer winner as business complexity and size increase.

Can I switch from ADP to Gusto?

Yes. Gusto has an ADP migration guide and will import employee data. The best time to switch is at the start of a new calendar year to simplify W-2 processing. Gusto's onboarding team assists with the migration at no additional charge.

Which payroll software integrates better with accounting software?

Both Gusto and ADP integrate with major accounting platforms (QuickBooks, Xero). Gusto's integrations are generally considered smoother and more automated. ADP's integrations vary by product tier and may require manual configuration.
