WooCommerce PayPal Payments 4.0.4 amount mismatches
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.
What changed?
- 4.0.3 — April 27, 2026: the last known stable version for the merchant who reported the double-discount issue.
- 4.0.4 — May 19, 2026: 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 — June 23, 2026: the stable changelog lists several 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. Stores that skipped 4.0.4, had no discounted PayPal orders during the window, or already reconciled without mismatch may not be affected.
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 |
| Already updated to 4.1.0 | Verify the fix on representative orders | Test coupons, reward points, gift cards, tax-inclusive orders, refunds, and accounting exports |
| 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 first on PayPal orders with coupons, reward points, gift cards, negative fees, inclusive tax, subscriptions, and unusual discounts.
- Compare order-level amounts. For each suspect order, 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.
- Deploy during a low-volume window. Monitor the first live discounted PayPal orders and compare them immediately against PayPal.
- Document unresolved losses separately. Keep a list of 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.
