What changed around WooCommerce PayPal Payments 4.0.4?

Public support threads reported amount-related problems after updating from 4.0.3 to 4.0.4, including a discount being applied twice and a one-cent PayPal order-total mismatch. Version 4.1.0 later shipped fixes for inclusive-tax rounding, negative fee calculation, gift-card calculation, and PayPal/WooCommerce amount mismatches.

Should every store immediately update to 4.1.0?

Stores affected by 4.0.4 amount mismatches should test 4.1.0 in staging, reconcile affected PayPal transactions against WooCommerce orders, and then update production during a low-volume window.

What should affected merchants audit?

Compare WooCommerce order totals, PayPal transaction totals, discounts, gift cards, negative fees, tax rounding, refunds, and accounting exports for orders created while running 4.0.4.

WooCommerce PayPal 4.0.4 discount applied twice / amount mismatch

Reviewed August 3, 2026Evidence confidence: Public support reports plus official 4.1.0 changelog fixesPrimary domain: Revenue / accounting accuracy

Current decisionStores that processed discounted, gift-card, negative-fee, subscription, or tax-sensitive PayPal orders on version 4.0.4 should audit PayPal totals against WooCommerce totals. If mismatches appear, test and move to 4.1.0; if a store is stable on 4.0.3, test 4.1.0 before updating production.

Two public support threads describe amount-related issues after updating WooCommerce PayPal Payments from 4.0.3 to 4.0.4: one reported a reward-points discount being deducted twice, and another reported a one-cent PayPal settlement mismatch on inclusive-tax coupon orders. Plugin support acknowledged known 4.0.4-related amount issues and pointed users toward the next fixed release path.

Version 4.1.0, released June 23, 2026, includes several amount-related fixes, including PayPal amount mismatch from inclusive-tax rounding, negative-fee calculation mismatch, third-party gift-card calculation, and mismatched line items not delivered to the PayPal transaction overview.

Do not treat this as only a display bug.If PayPal received or settled a different amount than WooCommerce expected, the store may need order-level reconciliation before closing accounting, refunds, or customer-support questions.

What changed?

4.0.4: affected users reported amount mismatches after updating from 4.0.3.
4.1.0-rc4: support said the one-cent mismatch had already been addressed in a release candidate.
4.1.0: the stable changelog lists fixes related to amount mismatch, rounding, negative fees, gift cards, and line items.

Who is affected?

This record matters most when your store used WooCommerce PayPal Payments 4.0.4 and processed orders with coupons, reward points, third-party gift cards, negative fees, inclusive tax, subscriptions with heavy discounts, or accounting workflows that depend on exact PayPal settlement totals.

What should you do?

Your situation	Primary decision	Safeguard
Running 4.0.4 and seeing PayPal/WooCommerce total mismatches	Audit and update after staging 4.1.0	Compare affected order totals, PayPal settlement totals, discounts, fees, tax, and refunds before closing the books
Rolled back to 4.0.3 and the store is stable	Stay stable while testing 4.1.0	Do not re-enter 4.0.4; test real coupon/gift-card/tax scenarios in staging
You had customer or merchant financial loss	Escalate privately through support	Prepare order IDs, PayPal transaction IDs, screenshots, plugin version history, and the related support-thread URL

Safest reconciliation sequence

Identify the exposure window. Record when 4.0.4 was installed and when 4.1.0 or 4.0.3 replaced it.
Filter affected order types. Focus on PayPal orders with coupons, reward points, gift cards, negative fees, inclusive tax, subscriptions, and unusual discounts.
Compare order-level amounts. Compare WooCommerce total, PayPal transaction total, discount lines, tax, fees, refunds, and payout records.
Back up and test 4.1.0 in staging. Recreate the same discount/tax/payment scenarios before production deployment.
Document unresolved losses separately. Keep affected transaction IDs, amounts, customer impact, and support correspondence.

What is not yet proven?

The public evidence shows real amount-mismatch reports and official 4.1.0 fixes in the same area. It does not prove that every 4.0.4 store had incorrect totals, that all reward-points or gift-card plugins were affected, or that every mismatch has the same root cause. The correct action is targeted reconciliation, not assuming all 4.0.4 orders are wrong.

Escalate before closing accounting when: PayPal settled more or less than WooCommerce recorded, discounts appear twice, tax-inclusive orders differ by cents across many transactions, refunds do not match the collected amount, or management is asking about recovery for financial loss.
