Overview
Bill.com and QuickBooks Online are designed to work together, but without the integration configured properly, businesses end up doing double data entry — entering invoices in Bill.com for approvals, then manually recording payments in QuickBooks. The native Bill.com-QuickBooks sync eliminates this entirely: invoices created in Bill.com appear in QuickBooks, approvals sync, payments record automatically, and bank reconciliation is dramatically faster. This integration alone saves most bookkeepers 3-5 hours per week.
Before you start
- Bill.com Essentials plan or higher
- QuickBooks Online account (Simple Start or higher)
- Admin access to both Bill.com and QuickBooks
Step-by-step guide (5 steps)
Enable the QuickBooks integration in Bill.com
In Bill.com → Settings → Integrations → QuickBooks Online, click 'Connect'. Authorize Bill.com to access your QuickBooks company file. Bill.com will sync your chart of accounts, vendors, and customers automatically during initial setup.
Map Bill.com fields to QuickBooks accounts
After connecting, go to Bill.com → Settings → Integrations → Chart of Accounts. Map Bill.com expense categories to the correct QuickBooks GL accounts. This ensures every bill is coded correctly in QuickBooks without manual categorization.
Spend time getting the account mapping right upfront. If expense categories don't match, you'll have miscoded transactions in QuickBooks that require manual correction.
Configure sync frequency and direction
Set the sync to run automatically (Bill.com syncs to QuickBooks every time an action is taken: bill created, approved, or paid). Verify that the sync direction is correct: Bills flow from Bill.com to QuickBooks, not the other way around.
Test with a real bill and payment
Create a test bill in Bill.com, approve it, and process a test payment. Then log into QuickBooks and verify: the bill appears under Accounts Payable, the payment records under the correct bank account, and the vendor balance reflects the payment.
Set up a monthly sync audit
Schedule a monthly review: compare Bill.com payment records with QuickBooks bank feed for the same period. Any discrepancies indicate a sync failure that needs investigation. Bill.com provides a sync log in Settings → Integrations → Sync History.
What you'll get
Zero double data entry between Bill.com and QuickBooks
Bank reconciliation takes minutes instead of hours
Chart of accounts stays clean with automatic GL coding
Bookkeeper saves 3-5 hours per week on manual entry
Common mistakes to avoid
Not mapping GL accounts correctly during setup — results in miscoded expenses in QuickBooks
Running the sync in both directions (QuickBooks → Bill.com) which creates duplicates
Not testing with a real transaction before going fully live
Ignoring the sync history log — failed syncs can go unnoticed for weeks
