Transaction Processing Excellence (TPE)

Mastercard's Transaction Processing Excellence (TPE) is a suite of compliance and network-efficiency programmes that penalise merchants, acquirers, and issuers for suboptimal authorization behaviour. TPE programmes are governed by the Transaction Processing Rules (TPR) and the Security Rules and Procedures Merchant Edition (SPME). Mastercard Academy offers a dedicated training course for acquirers and merchants. ^[1]

TPE fees appear on merchant statements up to two months after the triggering event due to Mastercard's billing cycle lag. (Merchant Cost Consulting, October 2025; Adyen Help Centre, 2026)

Sub-programmes

1. Excessive Authorization Attempts

Penalises merchants who retry declined authorizations too frequently on the same PAN and MID.

Triggers (Adyen Help Centre, 2026):

• More than 10 authorization attempts within a 24-hour window (more than 7 in Brazil and LATAM)
• More than 35 attempts on the same PAN/MID/amount within a rolling 30-day period

The EU 35/30-day threshold was established effective 1 August 2024; first billing September 8, 2024. (Braintree SU24, 2024)

Fee schedule (as-of 2025-01):

Region	Fee per excess attempt
US	$0.50 USD
Europe/EU	€0.55
APAC	$0.50 USD
Canada	$0.50 USD
Brazil	2 BRL
MEA	$0.55 USD
LATAM	$0.50 USD

(Adyen Help Centre, 2026; Braintree F23, October 2023; Braintree SU24, 2024)

Historical escalation — US fee (as-of 2025-01): $0.10 (original) → $0.15 (January 2023) → $0.30 (January 2024) → $0.50 (January 2025). (Merchant Cost Consulting, October 2025; Braintree F23, October 2023)

Mitigation: Adyen's ERPS (Excessive Retry Prevention Service); smart retry platforms (e.g., Stripe Smart Retries, Adyen Auto Rescue). Excessive retries also worsen future approval rates because issuers begin to tighten risk policies against persistent requesters. (Sumeet Bhatt / PYMNTS TV, November 2024)

2. Authorization Optimizer (MAC Fee)

The Authorization Optimizer programme (AN 6042) was introduced in October 2023 (US/Canada/EU) to guide merchants on optimal retry timing for Soft Decline|decline code 51 (insufficient funds). When a CNP transaction is declined with code 51, Mastercard sends a MAC (Merchant Advice Code)|Merchant Advice Code (MAC) 24–30 in the authorization response, specifying the optimal retry window. (Braintree F23, October 2023)

MAC retry intervals (as-of 2026-07): (TabaPay, July 2026)

MAC	Retry after
24	1 hour
25	24 hours
26	2 days
27	4 days
28	6 days
29	8 days
30	10 days

Key MAC codes — do-not-retry signals:

• MAC 01: New account information available → update stored credentials
• MAC 03: Do not try again (account closed or fraud suspected)
• MAC 21: Payment Cancellation (customer cancelled recurring agreement)
• MAC 40: Consumer non-reloadable prepaid card
• MAC 41: Consumer single-use virtual card number (unsuitable for subscriptions)

(TabaPay, July 2026; Braintree F23, October 2023)

New network response codes (NRCs) introduced alongside Authorization Optimizer (TabaPay, July 2026):

• NRC 79 (Lifecycle): replaces NRC 14 (invalid card) and 54 (expired card) — with MAC 03: do not retry
• NRC 82 (Policy): replaces NRC 57 (not permitted) and 62 (restricted card) — with MAC 03: do not retry
• NRC 83 (Fraud/Security): replaces NRC 14 and 43 (stolen card) — with MAC 03: fraud suspected, do not retry

MAC Fee: A fee applies per qualifying CNP transaction whether or not the merchant acts on the MAC advice — framed as a network data service charge. (Braintree F23, October 2023; IXOPAY, September 2025)

From January 2026: Scope expanded — MAC Fee now applies to ALL declined CNP transactions with MAC 03 or 21, not just re-tries within 30 days. (Merchant Cost Consulting, October 2025)

MAC Fee schedule (as-of 2026): (Adyen Help Centre, 2026; Merchant Cost Consulting, October 2025)

Region	Fee per qualifying transaction
US	$0.03
Europe	€0.50
Canada	$0.03
MEA	$0.40
APAC	$0.50
Brazil	2.50 BRL
LATAM	$0.50

Effectiveness benchmarks (as-of 2024-11): (Sumeet Bhatt, SVP Payment Optimization, Mastercard / PYMNTS TV, November 2024)

• Authorization Optimizer uses over 300 features to determine optimal retry timing
• Average 18% increase in conversions for merchants following optimizer advice
• Over $14 billion in incremental revenue generated for merchants since programme launch
• 99% accuracy for classifying "terminal declines" (MAC 03/21 — do not retry)
• 48% of subscription declines attributed to insufficient funds

3. Nominal Authorization

Penalises merchants who use micro-amount authorizations (≤ 2 full units of local currency or 2 USD) for card verification instead of the designated Account Status Inquiry (ASI) service. The fee triggers when such a low-value CNP authorization is approved and then reversed within 48 hours. (Braintree SU24, effective 1 January 2025)

Fee (as-of 2025-10):

• US: $0.045 per transaction (Merchant Cost Consulting, October 2025)
• APAC: $0.10 USD per transaction (effective 2 September 2024 revision) (Braintree SU24, 2024)

---

4. Undefined Authorization

An authorization submitted without a clear final-authorization flag. As of 18 June 2025, undefined authorizations are no longer a permitted type of dual message authorization in most circumstances. (Merchant Cost Consulting, October 2025)

Fee schedule (as-of 2025-10):

Period	Rate	Minimum
Launch – December 2025	0.25% of transaction	$0.04
From January 2026	0.30%	$0.05
From January 2027	0.35%	$0.10

(Merchant Cost Consulting, October 2025)

5. Pre-Authorization Fee

Applied to pre-authorization transactions. Fee: $0.045 per transaction (as-of 2025-10). (Merchant Cost Consulting, October 2025)

---

6. Final Authorization Fee

Triggers when the capture amount differs from the authorized amount (requires a new authorization for any overage). Fee: 0.25% of transaction value ($0.04 minimum). Added July 2025. (as-of 2025-09) (IXOPAY, September 2025)

---

7. Detail Reporting Fee

Applied on each TPE-triggering authorization event. Fee: $0.012 per transaction (as-of 2025-10). (Merchant Cost Consulting, October 2025)

---

8. Time-Based Authorization Validity (EU/EEA/UK/Gibraltar)

Penalises merchants who submit clearing transactions significantly after the authorization date. (Braintree SU24, 2024)

• Phase 1 (effective 6 January 2025): 0.006% fee (capped at €0.60) for clearing submitted 72–168 hours after final authorization approval
• Phase 2 (effective 4 January 2027): Adds 0.002% fee (capped at €0.20) for clearing submitted 24–72 hours after authorization

Related programmes and adjacent tools

Credential Continuity Program (CCP)

A recurring-payment compliance programme penalising merchants who process recurring transactions using outdated card credentials when an updated credential was available ≥ 10 days prior. (Braintree F25, September 2025)

• US effective 1 April 2025: $0.09 per transaction (raised from $0.03) (as-of 2025-09)
• APAC effective 1 February 2026
• Avoidance: Network Tokenisation, Automatic Billing Updater (ABU), proactive cardholder contact

Not strictly a TPE sub-programme but governed by the same network rules framework.

Payment Optimization Platform (POP) — adjacent acquirer tool

Launched October 13, 2025 by Mastercard as an acquirer/merchant-facing data enrichment service. Distinct from the Authorization Optimizer compliance programme — POP enriches authorization messages proactively to reduce declines, while Authorization Optimizer governs retry behaviour after declines occur. (Mastercard US Newsroom, October 2025, PRIMARY)

• Evaluates "over a trillion combinations of data elements" to generate the most optimal authorization message (as-of 2025-10)
• Pilot conversion uplift: 9–15% (as-of 2025-10)
• Launch partners: Adyen, NEOPAY, Tap Payments, Worldpay (as-of 2025-10)
• Commercial pricing not publicly disclosed
• AI capabilities to be integrated post-pilot

Note: No source explicitly positions POP inside the TPE compliance framework. POP is a value-added service; TPE is a penalty regime. They operate at different points in the authorization lifecycle.

On-Demand Decisioning (ODD) — adjacent issuer tool

Launched September 9, 2025 at the Mastercard RiskX summit in Rome. An issuer-facing tool, not a merchant compliance programme. ODD allows financial institutions to define customised decisioning criteria directly on the Mastercard network. (Mastercard Investor Relations, September 2025, PRIMARY)

• "First offering of its kind" allowing issuers to automate and enforce unique business logic
• Two modes: Mastercard responds proactively on the issuer's behalf, OR reviews and modifies the issuer's existing decision
• Global availability (excluding India): October 2025 (as-of 2025-09)

Relationship to TPE: ODD allows issuers to reduce miscategorised declines, which in turn reduces merchants' risk of falling into Excessive Authorization Attempts territory by retry necessity. ODD is issuer-side; TPE is merchant/acquirer-side.

Case study: Porto Bank — "contributed to the optimization of our authorization strategy, especially by preserving the experience of high-value customers. The solution required no implementation effort." (Nelson Aguiar, Executive Director, Porto Bank / Mastercard Investor Relations, September 2025)

Mastercard's decline taxonomy

Mastercard frames the TPE suite around a specific decline taxonomy (Tine Fincioen, EVP Digital Transformation, Mastercard / PYMNTS TV, October 2024):

"There are only two types of declines that are valid: true fraud attacks — not the fear of fraud — and when a consumer lacks funds or has reached their credit limit."

Sumeet Bhatt, SVP Payment Optimization (PYMNTS TV, November 2024): "92% of declines are either due to poor lifecycle management, suspected fraud, insufficient funds, lack of funds, and issuers' risk policies" — all addressable. Mastercard categorises declines as:

• Addressable: Soft declines with remediation paths — insufficient funds (retry via Authorization Optimizer), stale credentials (fix via CCP/Network Tokenisation), issuer policy miscalibration (improve via On-Demand Decisioning (ODD)|ODD), lifecycle-related (update via Card Account Updater)
• Terminal: MAC 03 / MAC 21 — do not retry; retrying these triggers Excessive Authorization Attempts fees and worsens future issuer disposition

Tokenization impact (as-of 2026-06): "Three in five Mastercard ecommerce transactions in Europe are now processed using tokens rather than static card credentials," reducing lifecycle-related declines automatically. Merchant tokenization (Secure Card on File) live in 45 European countries. (Mastercard Europe Newsroom, June 2026, PRIMARY)
