You need to map your Zoho Books products (items) to your Hyperline product catalog.

When specified, Hyperline automatically attaches each invoice line item to the corresponding item in Zoho Books.Zoho Books requires all Hyperline invoice line items to be mapped to Zoho Books items. If a product is not mapped, the invoice will not be created in Zoho Books.

Synchronization rules
Synchronization rules select the Zoho Books account for each invoice or credit note line.

In Synchronisation rules, open the rule count card or No rules configured, then click Add rule.
- Select the Invoicing entity if prompted and enter a descriptive Name.
- Under Applied on, filter by products, product type, coupons, currency, country, tax scheme, tax territory, tax rate class, billing interval, invoice types, or custom properties.
- Under Account configuration, select a Revenue account. Use Sync accounts from Zoho Books to refresh the available accounts.
- Click Save changes.
Example 💡
Map your implementation service to its Zoho Books item, then create a rule filtered to that product and select your services revenue account. The invoice line keeps its item mapping and uses the rule’s account.
Transaction and journal rules are not available for Zoho Books. Invoice account rules do not change payment synchronization settings.
