When a direct plugin can be enough
If the store is small, the posting rules are simple and one invoice per order is acceptable, keeping the integration inside WooCommerce may be convenient. There is no reason to add a SaaS layer solely for complexity's sake.
Why a separate control layer can help
As order volume grows, the accounting problem moves beyond connectivity. Finance teams may need paid-date summaries, separate handling for BACS trade orders, mapping changes, preview before export and history that spans more than one store.
Tenant-level control matters for multi-store companies
ClearCommerce groups stores under a company and keeps the Xero connection and accounting configuration at the correct tenant boundary. That makes it easier to add another store without copying plugin settings manually between websites.
