Payroll5 connections recorded

Short answer. All five post payroll to QuickBooks Online as journal entries; the differences are detail, timing and how much you fix by hand. Gusto and OnPay post automatically after each run with clear mapping rules. ADP RUN can auto-post but routes net pay through a clearing account and leaves some items to enter manually. Paychex Flex syncs through its General Ledger Service add-on. Rippling maps payroll to classes, departments and locations.

Check before you connect

MappingEvery earnings type, tax and deduction needs a QuickBooks account; new deductions break syncs until mapped.
Detail levelSummary entries keep the ledger clean; detailed entries per employee help job costing.
Classes and locationsIf you report by class or location, check how many dimensions a journal can carry.
Manual itemsAsk what is left to enter by hand: fees, workers’ comp, manual checks.

Connections, by situation

Automatic and well documented

Choose summary or detail

OnPay

Documented limits

Connection	Limits the vendor documents
Gusto	Every Gusto category needs a mapped account; A/R and A/P account types are not supported. Only one QuickBooks class per journal entry.
OnPay	Unmapped accounts stop the automatic send until fixed. Mapping an A/P account to several lines prevents syncing.
RUN Powered by ADP (General Ledger)	Net pay runs through an ADP clearing account you add in QuickBooks. Some items (invoice fees, workers’ comp) are entered manually per ADP’s guide.
Paychex Flex (General Ledger Service)	Mapping details for the online connection are not published on the pages checked.
Rippling	Rippling’s own materials describe class, department and location mapping but not QuickBooks-specific limits.

What “integrates” means for payroll

Payroll integrations post accounting entries; they do not make QuickBooks run payroll. Your payroll provider still files taxes and pays people. The integration saves re-keying and keeps the ledger in step.

Before you connect

Create the liability and clearing accounts the provider expects, map every pay item, and sync one payroll for a period that is still open. Do not sync into a closed period.
