SIERRA Xero app

Sierra is the perfect companion for businesses using Xero. Designed with automation in mind, Sierra takes care of the repetitive, manual tasks so you can focus on what truly matters – growing your business.


Sierra currently can automatically create a withholding tax bill based on your subscription bill. This will ease reconciliation, avoid late payment penalty and ease audit and tax processes.

If you have many recurring or one time payment to foreign entities that incurr withholding tax, managing withholding tax payments to LHDN is important to ensure compliance, avoid late penalty and ease of audit & tax process. Example of transaction that incurred withholding tax are subscription to Zoom, Facebook Ads, Google Ads, Xero, Bitrix24, GCP, DigitalOcean and many more.

Our approach is designed to ease reconciliation and to ensure every payment made via e-WHT automatically reconciled to the WHT bill that was automatically created by Sierra.
