Invoice Settings — Tax, Shipping

Purpose

Answer: “How do invoices update when orders are edited, upsells are added, or taxes and shipping change?” This article explains how Account Editor controls invoice accuracy, tax recalculation, shipping updates, and invoice layout after post-purchase edits.

Why This Matters

Invoices are customer-facing financial documents. If they’re incorrect, unclear, or inconsistent, merchants face:

• Customer disputes
• Accounting mismatches
• Tax compliance issues
• Support tickets around “wrong invoice” or “missing item”

Account Editor ensures invoices stay accurate, updated, and professional — even after order edits.

How Invoice Updates Work in Account Editor

Whenever a customer edits an order:

• Adds or removes items
• Changes quantity or variants
• Updates shipping method or address
• Accepts an upsell

Account Editor automatically triggers Shopify to:

• Recalculate subtotal
• Recalculate discounts
• Recalculate taxes 
• Recalculate shipping
• Update the same invoice (no duplicates)

 Important: Invoices always reflect the final order state, not intermediate or unpaid edits.

Tax Recalculation Logic

When Taxes Update Automatically

Taxes are recalculated when:

• Products are added or removed
• Quantities change
• Shipping address changes (state / country)
• Shipping method changes

Account Editor uses Shopify’s native tax engine, so:

• Tax is determined by address
• Tax / regional tax rules apply automatically
• No manual tax logic is required

 Best practice: Always enable Recalculate tax on edit to avoid incorrect invoices.

Shipping Recalculation on Invoice

If shipping recalculation is enabled:

• Adding heavier items may increase shipping
• Crossing free-shipping thresholds may reduce shipping
• Changing shipping method updates shipping cost

All changes are reflected immediately on the invoice.

Reverse Unpaid Order Edits (Invoice Safety)

If a customer:

• Adds items
• Increases order value
• Fails to complete payment

And Reverse unpaid order edits is enabled:

• Order reverts to original state
• Invoice also reverts automatically
• No unpaid or partial invoice is shown to customers

This prevents:

• “Invoice shows items I didn’t pay for”
• Finance reconciliation issues

Invoice Templates — Layout, Branding & Customer View

Account Editor lets you control how the invoice looks, not just what it contains.

Change Invoice Template

Path: Account Editor Admin → Settings → Invoice Settings → Invoice Template You can choose which invoice layout customers see and download. Available templates:

• Default
• Primary
• Secondary
• Tertiary

Each template differs in:

• Layout structure
• Visual hierarchy
• Spacing and readability

• Store name & branding
