The field works in FieldSub. The books stay in QuickBooks. Nobody types twice.
FieldSub's QuickBooks Online integration syncs invoices, customers, payments, bills and items in both directions, imports your existing customers and open invoices when you connect, and can seed your estimating catalog from your QuickBooks items.
Connect once, import everything
Connect with your QuickBooks login. FieldSub imports customers and open invoices, matches customers you already have, and flags anything that needs a human decision instead of guessing.
Two-way, and it stays that way
Invoices created in FieldSub appear in QuickBooks. Payments recorded in either place show up in the other. Bills and items sync too, and QuickBooks changes arrive in FieldSub through change notifications, not a nightly batch.
Keep billing where it already lives
For projects you would rather bill from QuickBooks, switch that project's billing to QuickBooks and FieldSub follows along. Turn on online payments and invoices go out with a QuickBooks pay link, so clients pay by card or ACH. A sync ledger shows every record that moved, in which direction, and when, so reconciliation is a lookup instead of a hunt.

Yes. That is the point: the field and the office use FieldSub, the books stay in QuickBooks, and the sync keeps both current.
