US Shopware programs: tax, shipping, and when Rule Builder needs backup

US Shopware programs stall when teams treat tax and shipping as “configuration we will tune later.” In production, those paths touch your tax engine, carrier APIs, ERP allocations, and customer expectations at checkout—so they belong in discovery with the same weight as catalog mapping.

Rule Builder is powerful—know where it stops

Shopware’s rules cover many zone, method, and surcharge patterns. When you hit customer-specific freight, multi-origin fulfillment, or exemption logic your finance team signs off on, you may need apps or custom plugins with logging—not an ever-growing nest of opaque rules nobody can audit.

Integrate the engines you already trust

Shopware should orchestrate; your tax service and carrier platforms should still own their domains. Irish Titan maps contracts, failure modes, and reconciliation so totals match what operations expect—then proves it with rehearsal orders before cutover.
