The Alto integration allows information from Alto to sync into InventoryBase, helping reduce manual data entry and keeping your inspection workflow connected to your wider property management process.
Alto is used to manage your property, tenancy, landlord, tenant, and appointment records. InventoryBase is used to manage inspections, capture property condition evidence, and produce inspection reports.

Before You Connect Alto
Before Alto can be connected to InventoryBase, InventoryBase must be activated from the Alto Marketplace.
This allows Alto to send InventoryBase the required AgencyRef / branch reference details for your account. These details tell us which Alto branch, or branches, should be connected to your InventoryBase account.
Alto may provide:
a branch-level AgencyRef for individual branches
a group-level AgencyRef for multiple enabled branches
Once these details have been received, InventoryBase will complete the connection for your InventoryBase account.
How to Start the Connection
Log in to your InventoryBase online dashboard.
Go to Settings.
Select Integrations.
Find Alto Integration.
Click Connect Alto.
Follow the prompts to continue through the Alto Marketplace.
Once you have completed the Alto Marketplace steps, Alto will send the required AgencyRef / branch reference details to InventoryBase.
Our team will then complete the connection for your account.
Once Alto is Connected
Once connected, you will see the Alto integration settings in InventoryBase.
From here, you can manage how Alto data syncs into InventoryBase, including:
property syncing
inspection syncing
appointment type mapping
negotiator settings
tenancy settings
contact and landlord import settings
completed report upload settings
ℹ️ These settings are covered in the next guide:
Important Things to Know
Before using the Alto integration, please note:
Alto is the source of the property, appointment, contact, negotiator, and tenancy data.
InventoryBase inspections are created from Alto appointments.
Inspections created directly in InventoryBase do not create new Alto appointments. However, for inspections originally created from Alto appointments, some supported changes may sync back to the linked Alto appointment if Sync Inspection Changes is enabled.
Completed reports can only sync back to Alto for inspections created from Alto appointments.
If a property is archived in Alto, it is not automatically removed from InventoryBase.
Some optional functionality, such as webhooks, may be available on request but is not enabled by default.
