Integration with QuickBooks Online

What you will need

Sales tax enabled in QuickBooks Online.
A Bank-type account in your QuickBooks Chart of Accounts. Titus uses this as the deposit account for synced payouts and refunds.
A fee account in your Chart of Accounts (typically an Expense account). Titus uses this to record processing fees.

Sales Tax Handling

To sync invoice sales tax from Titus, Sales Tax must be enabled in QuickBooks Online.
For Titus-synced invoices, Titus sends the invoice tax amount as a transaction-level tax override in QuickBooks.
If a different tax rate is configured in QuickBooks, the Titus-synced tax amount still determines the invoice tax total.
Important: If tax is edited on a Titus-synced QuickBooks invoice, its total will no longer match the Titus invoice total, which can lead to inconsistent payment status in QuickBooks.

Connecting to QuickBooks

In Titus, go to Settings → Integrations.
Find QuickBooks and click Connect.
Choose your Start from date.
1. Titus will sync invoices and related transactions from this date forward.
Complete the QuickBooks authorization flow.
Back in Titus, select your QuickBooks accounts:
- Deposit account: the Bank account where you track incoming deposits/refunds.
- Fee account: the account (usually Expense) where you track Titus processing fees.

Note: If you have any connection issues with QuickBooks, see FAQs below for troubleshooting.

After Connecting

QuickBooks will appear as Connected in your Integrations settings.
On the Invoices page, each invoice will display its last QuickBooks sync timestamp.
Titus starts backfilling Invoices and Payments from your selected start date
Payout and refund backfilling begins once your QuickBooks deposit and fee accounts are configured.
In invoice creation, Browse catalog now includes a QuickBooks catalog section so you can add QuickBooks products/services as invoice line items.

What is synced over

Titus record	Created as in QuickBooks	Notes
Customer	Customer	Created when needed for invoice/payment sync
Invoice	Invoice	Created for open/void/paid invoices; later edits update the same QuickBooks invoice
Invoice-linked payment	Payment	Created for completed invoice payments
Non-invoice-linked payment	SalesReceipt	Created for completed non-invoice payments
Payout/settlement batch	Deposit	Created for payouts; links related synced payments/sales receipts. Includes Titus processing fees as a deposit line item
Refund activity	RefundReceipt	Created for refunds

What counts as an eligible record

Eligibility is based on sync readiness and your Start from date.

Invoices: Open, Paid, or Void invoices that are not already synced and are created on/after the Start from date.
Invoice payments: Successful/completed payments linked to synced invoices, not already synced, created on/after the Start from date.
Sales receipts: Successful/completed payments not linked to invoices, not already synced, created on/after the Start from date.
Deposits: Eligible payout/settlement records (with required deposit/fee account settings), not already synced, dated on/after the Start from date.
Refund receipts: Supported successful/completed refunds tied to synced source records, not already synced, dated on/after the Start from date.

How Syncing Works

Sync direction: Titus → QuickBooks only (one-way). Changes made in QuickBooks do not sync back to Titus.
Initial backfill: After you connect QuickBooks, Titus syncs all eligible records from your Start from date forward.
Ongoing sync: After backfill completes, Titus continues syncing new invoice and payment activity from Titus to QuickBooks automatically.

Invoice edits

When an open invoice changes in Titus (customer, dates, totals, notes, or line items), Titus updates the existing QuickBooks invoice.

Voided invoices

When an invoice is voided in Titus, the linked QuickBooks invoice is voided.

If QuickBooks is disconnected after connecting

If changes happen while disconnected, Titus marks affected records for resync and catches up after reconnection.

Bank Reconciliation in QuickBooks

If QuickBooks is connected to your bank feed, downloaded entries in Bank Transactions can be matched to the Deposit and Refund Receipt transactions created by Titus sync.

FAQs

Do changes in QuickBooks sync back to Titus?
No, changes sync from Titus to QuickBooks only. Changes made in QuickBooks do not sync back to Titus.

Can I connect to different QuickBooks accounts?
We strongly recommend connecting only one QuickBooks account per Titus business. While switching accounts is technically possible, it can split your accounting history across multiple QuickBooks companies and cause inconsistencies. Titus does not re-sync records that were already synced to the previous account; only records that were still unsynced will sync to the new account.

How are taxes handled?

For invoice taxes to be synced over from Titus, you will need to turn on sales tax in your QuickBooks. Titus then syncs tax amounts as the override amount in QuickBooks invoices. If you have another tax rate enabled in QuickBooks, the amount that Titus syncs over will override the rate you have configured.

Do draft invoices sync?

No. Invoices sync when they are open, paid, or void.

Can I choose how far back Titus syncs?

Yes. You choose a start date during setup.

Do I need to set payout and fee accounts?

Yes. Those accounts are required for payout and refund sync.

What will not sync?

- Records before your selected start date.

- Draft invoices.

- Failed/pending (not completed) payment/refund activity.

What happens if I disconnect and reconnect again?
When you reconnect, Titus will sync records based on the eligibility outlined above. Records that have been previously synced will not result in duplicate records in QuickBooks.

Why is my QuickBooks stating there's a connection problem when I try to connect?
If your QuickBooks account is stating a connection issue, you can try one of the following.

Turn off VPN/ad blockers
Try opening in an Incognito/Private window
Try a different browser (Chrome preferred)
Log out and back into QuickBooks, then reconnect
Confirm you are a QuickBooks Admin of the business

Does Titus support QuickBooks Desktop?

No. This integration is for QuickBooks Online only.
