US tax, shipping & fulfillment rules

Shipping and tax are where US merchants feel Shopware first. We align Rule Builder configuration, extensions, and external engines so cart, checkout, and ERP reconciliation tell the same story.

How we approach it

  1. 1

    Rule matrix workshop

    Customer groups, regions, methods, surcharges, and exceptions—captured as an operator-readable matrix.

  2. 2

    Engine integration

    Wire tax services and carrier APIs with explicit failure fallbacks.

  3. 3

    Rehearsal orders

    Representative carts across catalogs and markets—totals reconciled to expectations.

  4. 4

    Launch monitoring

    Dashboards for tax and shipping errors in the first weeks post go-live.

Best practices

  • Reconcile money paths with finance

    Refunds, partial captures, and tax lines should match the GL story.

  • Document exemptions carefully

    Resale and nonprofit flows need audit-friendly trails.

  • Plan peak behavior

    Carrier outages and rate limits belong in the runbook—not Slack improvisation.

Irish Titan’s methodology starts with business first, online second — partnerships over transactions, then the platforms and marketing that ship outcomes. As a full-service agency we bring UX, design, and business process consulting alongside engineering and launch in the same delivery thread when your program needs it. We operate a Titan-only delivery model: the people doing the work are direct Irish Titan employees from our headquarters, not contractors or outsourced pods.
