Property finance and accounting teams who are onboarding to Mews with an accounting integration use this article to decide between joining the Ledger API pilot and starting on the existing integration. You make this choice with Omniboost while your accounting integration is being set up, and the article compares what each option involves, how your data is tested, and what happens afterwards.

How to decide whether to join the Ledger API pilot

Why am I being asked to join a pilot?

Mews is upgrading how financial data is sent from Mews to accounting systems. Our existing accounting integrations use reporting data that can still change within the reporting window. This means integrations need to wait before sending data to ensure it is complete.

 

We have since introduced Mews Ledgers, a new financial reporting framework based on immutable accounting data. Once a business day closes, the financial records for that day are fixed, with any later changes recorded transparently as corrections.

 

Mews Ledgers are already established in production and used by thousands of properties. We are now working with Omniboost to progressively move all accounting integrations onto APIs powered by this Ledger data. Several major integrations have already successfully moved to the new framework, and your accounting integration is now ready for pilot. This gives you two options as you onboard to Mews.

 

Which integrations can join the pilot today?

The Ledger API pilot is currently open for:

• Datev

• Sage Intacct

• Sage Coala

• Sage 50 UK

• Sage Generation Expert

• Hotel Investor Apps

• Exact Online

• Exact Globe

• Twinfield

• Fortnox

• Visma.net

• Visma Business

• BMD NTCS

 

We're adding more integrations as we prioritize them. If yours isn't listed and you'd like it moved up the list, reach out to your Mews CSM or [email protected].

 

Your options

The table compares joining the Ledger API pilot with using the existing integration.

 

	Join the Ledger API pilot	Use the existing integration
What happens now?	Omniboost connects you directly to the new Ledger-based integration. You control the pace: you move onto live ledger data once you've confirmed your validated data looks correct.	Omniboost connects you to the existing integration. When it's time to move to the Ledger-based version, Mews will communicate your switch date to you directly.
Will it be tested?	Yes. Omniboost will work with you to validate the setup and data. You will validate up to one month of financial data, depending on the integration complexity, allowing for more comprehensive checks and closer collaboration with the Omniboost team.	Yes. You will typically validate seven days of financial data, comparing the test data provided with the corresponding data in Mews.
Will I need to migrate the integration later?	No. You start directly on the integration Mews is moving towards.	Yes. Once the new integration is released, your property will eventually be migrated to it.
Additional considerations	As this integration is still in pilot, additional issues may be identified compared with the established integration. Any pilot issues will be treated as a top priority by Omniboost. We also ask for active participation, including up to two 30-minute calls and timely feedback.	You avoid participating in the pilot, but will need to transition to the new integration later.

 

What are the benefits of joining the pilot?

Starting directly with the Ledger-based integration means:

• More comprehensive validation: a longer period of financial data is checked than the standard seven days.

• Higher-touch support and priority resolution: closer collaboration with Omniboost throughout the pilot, with any pilot-related integration issues treated as a top priority.

• Ledger benefits from day one: faster accounting data availability, direct reconciliation with Mews Ledgers and transparent corrections.

• No migration later: you start directly on the Ledger-based integration, avoiding a future transition.

 

Your accounting data can therefore be reconciled directly against the new Mews financial reporting suite, including the Trial Balance and Ledger Activity Report.

 

What does being a pilot involve?

As with any accounting integration setup, you need to be fully configured in both Mews and your accounting system and validate the test data provided. For the Ledger API pilot, validation is more comprehensive:

• You will validate a longer period of financial data than the standard seven days, depending on integration complexity.

• We ask that you are available for up to two 30-minute calls with Omniboost and provide timely feedback.

 

As the integration is still being validated, additional issues may be identified. Any pilot-related issues will be treated as a top priority by Omniboost, with Mews and Omniboost working with you to resolve them.

 

Importantly, Mews Ledgers themselves are not in pilot. They are already used by thousands of properties, with key integrations such as Xero and QuickBooks already migrated. The pilot focuses specifically on your integration's connection to Ledger data.

 

How to join the pilot?

Let the Omniboost team know when discussing your integration needs, and also ensure your Mews Implementation manager is aware.

 

What if I don't want to join the pilot?

That's completely fine. You can onboard using the existing accounting integration.

 

Mews is progressively moving accounting integrations to the Ledger API, so once the Ledger-based version of your integration has completed its pilot and is ready for wider rollout, your property will eventually be migrated. We'll contact you in advance with information about the transition and any preparation required. The migration itself is handled automatically, with guidance provided to help you reconcile any differences around the transition.

 

FAQ

Which accounting integrations can join the pilot right now?

The pilot is currently limited to a specific set of integrations (Datev, Sage Intacct, Sage Coala, Sage 50 UK, Sage Generation Expert, Hotel Investor Apps, Exact Online, Exact Globe, Twinfield, Fortnox, Visma.net, Visma Business and BMD NTCS), and we're adding more as we prioritize them. If your integration isn't listed yet, you can still onboard on the existing integration now, and ask your Mews CSM or [email protected] to prioritize the Ledger API version for your integration.

 

Does joining the pilot change how I use my accounting system?

The pilot changes the source of the financial data sent from Mews, rather than your accounting system itself. Omniboost will confirm any integration-specific setup requirements with you.

 

Will my accounting data still be tested if I don't join the pilot?

Yes. With the existing integration, you will typically validate seven days of financial data. The pilot involves validating a longer period of data for more comprehensive checks.

 

What happens if we find a problem during the pilot?

Mews and Omniboost will work with you to investigate and resolve it. Any pilot-related integration issues will be treated as a top priority by Omniboost.

 

Are Mews Ledgers themselves still in pilot?

No. Mews Ledgers are already established in production and used by thousands of properties. The pilot is specifically for connecting your accounting integration to the Ledger API.

 

Will I have to change my accounting integration again later if I join the pilot?

No. You start directly on the Ledger-based integration rather than onboarding to the existing connection and migrating later.

 

What if I join the pilot but don't like the results, can I still connect to the old API?

Yes. Your existing connection keeps running in parallel while you validate the pilot data, so nothing changes for your live accounting feed until you're ready. If you decide not to continue, you simply stay on the existing integration and migrate later as part of the standard rollout, like any other property.

 

Where can I learn more about Mews Ledgers?

Who should I contact if I have questions?

Your Mews onboarding contact can answer questions and coordinate the integration setup with Omniboost.
