Capabilities
The boring parts of payroll, automated.
TwinBooks owns the operational data. Gusto owns the payroll engine. The integration keeps them in sync.
Two-way Gusto sync
Hire someone in TwinBooks, they appear in Gusto. Onboard a contractor in Gusto, they show up in TwinBooks. No copy-paste.
Federal & state withholding
Gusto calculates and files withholding for every jurisdiction your team works in. Quarterly returns are handled.
W-2s for employees
Generated and delivered every January. Form W-3 to the SSA and state wage reports filed automatically.
1099-NEC for contractors
Crossed the $600 threshold? Gusto generates, delivers, and files the 1099-NEC. The threshold check is automatic.
Direct deposit
Net pay lands in employee accounts on every pay run. No checks to print, no banking app to wrangle.
Hours from time entry
Weekly hours entered in TwinBooks roll up to Gusto with regular, overtime, and double-time multipliers applied.
The split
Who does what.
Rather than build payroll mechanics from scratch (and become responsible for tax filings in 50 states), TwinBooks pairs with Gusto. The integration draws a clean line between the two systems:
- TwinBooks owns the operational data. Employees, contractors, departments, job titles, hire dates, weekly hours, pay rates (regular / overtime / double-time), pay schedules, and time off.
- Gusto owns the payroll engine. Tax tables, garnishments, benefits, direct deposit ACH, federal & state withholding, quarterly returns, year-end forms.
- Both stay in sync. Hire someone in TwinBooks, they appear in Gusto. Onboard a contractor in Gusto, they show up in TwinBooks.
On the TwinBooks side, every payroll run posts to your P&L automatically: gross wages, employer taxes, benefits, and net pay each hit the right account. No journal entry, no dragging numbers from a Gusto PDF.
