Switching your QuickBooks integration to Mews ledger data FAQs

Mews is upgrading the way your property's QuickBooks accounting integration receives data. Instead of the legacy connection, your integration uses Mews ledger reports as its data source — giving you immutable, accounting-compliant entries that support a clean audit trail. This change affects all properties using a QuickBooks accounting integration through Omniboost for accrual (consumed) accounting flows. The switch happens automatically on a date communicated to you directly by email, so your finance team needs to know what to expect and how to prepare. With your QuickBooks integration switched to ledger data, your accounting system receives immutable, validated entries directly from Mews, giving your finance team a more reliable data source, a cleaner audit trail, and a setup that aligns with Mews reporting going forward.

Why is this switch happening?

Mews has rebuilt its financial reporting around ledger data — immutable, accounting-compliant entries that accurately reflect your property's financial activity. To reflect this, Omniboost is migrating your QuickBooks integration from the legacy connection to a new validated integration flow that sends ledger data directly to your accounting system.

Is this switch mandatory?

Yes. The legacy connection is being decommissioned, so all affected properties must be migrated by the date indicated in your migration email. The Omniboost team reaches out separately to update ledger mapping codes for more accurate postings.

Which properties are affected?

All properties using a QuickBooks accounting integration through Omniboost for accrual (consumed) accounting flows are affected. Integrations are migrated in phases, starting with the most used ones first. You receive an email with your specific switch date and next steps.

When is the switch happening?

The migration happens in phases over the coming months. You receive a direct communication telling you when the switch is planned for your property.

What do I need to do before the switch?

Once you receive your migration email, review the preparation steps in the help article How to prepare to switch your accounting integration to ledger data in Mews Operations. These steps are optional but help minimize and reconcile potential discrepancies between the old and new data source:

1. Adjust your Mews settings, such as your business day and editable history window.

2. Work with Omniboost to update your ledger mapping codes if you want more granular postings.

3. After the switch, review and reconcile any potential discrepancies between the old and new data source — see How to reconcile differences between legacy reporting and ledgers for guidance.

Make sure your finance or accounting team is available to support the process and can respond promptly if needed.

Note: No action is required on the day of the switch itself — the migration happens automatically.

Which settings may need to be updated in Omniboost?

By default, your existing guest ledger account code is used for ledger movement postings covering deposit, guest, and city ledgers. If you prefer more granular postings into your accounting system, you can update the relevant mapping codes with Omniboost.

Omniboost contacts you directly before your migration date with instructions to access or create your Base platform profile. Your Base platform profile allows you to review and update your ledger mapping codes, view your integration logs, and rerun data independently.

• If you already have a Base platform profile — Log in at app.omniboost.io/login, go to Integration Settings, and update the ledger account codes for the new ledgers before your migration date.
• If you do not yet have a Base platform profile — You receive an invitation from Omniboost to create your account ahead of the migration. Follow the instructions in that email to set up your profile and configure your ledger mapping. If you do not receive an invitation, contact [email protected] using the following format:

  • Subject: Base access needed for Mews Ledger migration

  • Property name

  • User name

  • User email address

Is there any downtime or data loss during the switch?

No. During the switch, both data sources temporarily overlap to make sure nothing is missed. Your accounting system continues receiving order item data as usual for the period up to the switch date, with an editable history window delay. During the editable history window period, ledger entries accumulate in the background and are sent as a backfill once the window closes. At that point, you also receive the final batch of order item data. After the transition completes, your accounting system receives only ledger entries going forward. There is no data loss and no downtime.

What happens if I miss the deadline?

The migration happens automatically, so your QuickBooks integration continues working without any action from you. However, if you take a few minutes to update your settings in Mews or Omniboost before the deadline, you can take advantage of the new, more granular ledger structure and help minimize potential discrepancies after the switch. If you do not update your settings, the integration continues using your current configuration, and transactions may remain grouped into broader ledger accounts rather than being separated across the new ledgers.

Who do I contact for support?

For any questions, reach out to the Mews support team by submitting a support ticket through the Mews Digital Assistant. The team advises you directly or liaises with Omniboost on your behalf if needed.
