Compliant surcharging that recovers 100% of card processing costs — state-by-state, card-by-card.
PaymentHub's surcharge engine manages compliant surcharging and convenience fees with entity-specific rules, state-level compliance, card brand adherence, and designated GL posting — recovering processing costs without legal or customer relationship risk.
The Problem This Solves
Before PaymentHub
Surcharge compliance varies by state and card brand. Non-compliant surcharging creates legal risk — several states prohibit or limit surcharges, and card brand rules cap surcharge percentages and require specific disclosures. Many organizations avoid surcharging entirely because the compliance complexity seems unmanageable. Those that do surcharge often do so inconsistently, missing entity-specific rules or failing to update when state laws change. Incorrect fee structures leave money on the table while creating customer confusion.
With PaymentHub
Surcharging is compliant by default. The rules engine evaluates state laws, card brand caps, and entity policies for every transaction. Customer disclosures are generated automatically. Surcharge revenue posts to designated GL accounts. Finance teams recover 100% of card processing costs on eligible transactions while maintaining full compliance. Entity-specific fee policies handle the complexity of multi-state, multi-entity operations without manual oversight.
How It Works
State-Level Compliance Engine
The surcharge rules engine maintains current state surcharge laws and evaluates each transaction against the applicable jurisdiction. States that prohibit surcharging (Connecticut, Massachusetts, Maine, Oklahoma, and others as laws evolve) are automatically excluded. States with surcharge caps or specific disclosure requirements have those rules applied automatically. The compliance database is updated when state laws change, ensuring ongoing compliance without manual monitoring. For organizations operating across multiple states, this eliminates the operational burden of tracking and applying jurisdiction-specific surcharge rules on every transaction.
Card Brand Rule Adherence
Visa, Mastercard, and other card brands impose specific surcharge requirements: maximum surcharge percentages (currently 3% for Visa, 4% for Mastercard), disclosure requirements at point of sale, and restrictions on which card types can be surcharged. The engine evaluates each transaction against the applicable card brand rules and applies the maximum permitted surcharge or the configured surcharge amount, whichever is lower. Debit cards, which generally cannot be surcharged under card brand rules, are automatically excluded. This brand-level compliance prevents the costly chargebacks and violations that result from non-compliant surcharging.
Entity-Specific Fee Policies
Each entity can define distinct surcharge and convenience fee policies. One entity might surcharge card payments at 2.5% while another applies a flat $3.50 convenience fee. Policies can vary by customer segment — wholesale customers might see a different fee structure than retail accounts. The policy engine evaluates entity, customer segment, payment method, transaction amount, and jurisdiction to determine the applicable fee for each transaction. Policies are configured through the admin interface and can be managed independently per entity without affecting other entities' fee structures.
GL Posting and Fee Accounting
Surcharge revenue posts to designated GL accounts separate from the payment amount. The posting engine generates the proper journal entries: the base payment amount credits the AR account, while the surcharge amount credits the designated fee income account. For organizations that split surcharge revenue by entity, department, or cost center, the posting rules accommodate entity-specific fee account mapping. This clean separation ensures that surcharge revenue is tracked accurately for financial reporting and that the true cost of payment processing is visible in the P&L.
Architecture & Integration Notes
The surcharge engine operates as a pre-payment evaluation step in the payment processing pipeline. Before the payment amount is finalized, the engine evaluates the jurisdiction, card brand, entity policy, and customer segment to determine the applicable surcharge. The surcharge amount is presented to the customer with the required disclosure messaging before payment confirmation. After payment, the posting engine splits the base amount and surcharge amount into their respective GL accounts. Before/after hooks on the fee evaluation step allow injection of custom logic — for example, a hook that waives surcharges for accounts above a certain annual volume, or that applies different surcharge rates during promotional periods. Fee policies are versioned and upgrade-safe.
AI Copilot for Surcharge Engine
The AI copilot analyzes your transaction data to recommend optimal surcharge configurations by entity and customer segment. It projects revenue recovery under different fee scenarios, identifies customer segments where surcharging may impact payment behavior (and suggests alternative incentives like ACH-first pricing for those segments), and generates the compliance documentation and customer communication templates needed for surcharge implementation. During production, the copilot monitors surcharge acceptance rates and flags any jurisdiction or card brand rule changes that require policy updates.
