Every way to get paid, through one integration.
CSIPay owns and operates its own gateway, so the product roadmap answers to Constellation operating companies. One integration covers online, in person, mobile, and bank payments across the full lifecycle, from initiation to settlement and reporting.
Everything connected. One seamless payment.
One pay page brings every online payment method together, so merchants get paid anywhere online.
Pay By Link
No account needed. Share a link and get paid instantly, for one time or recurring collection.
Hosted checkout
Secure, branded, and reliable, with no card data touching partner systems.
E-commerce and recurring
Built for scale, with recurring billing and subscriptions for scheduled charges.
ACH and bank pay
Low fees, direct from bank to bank, for higher ticket and account based workflows.
Digital wallets
Apple Pay and Google Pay are live across card not present transactions, with the framework to add more.
Turn any phone into a terminal
Application based acceptance, with or without dedicated hardware, so every staff member and every space becomes a checkout.
Tap to pay on phone
Accept contactless cards and digital wallets on the device itself, with no extra hardware.
With or without terminals
One app spans countertop terminals, mobile readers, and phone only acceptance.
Line busting and pay at table
Bring checkout to the customer, in the aisle, on the floor, or at the table.
Field service and delivery
Cellular connected acceptance settles on site, at the door, or on the job.
iOS and Android
EMV, NFC, and QR. Pairs with Axium readers.
One portal. Every merchant.
From onboarding and underwriting through reporting and disputes, manage the entire merchant relationship in one place.
Onboarding and underwriting
Identity validation, risk based underwriting, and faster approvals for most low and medium risk merchants.
Merchant management
User and access controls, with full merchant lifecycle visibility.
Transaction search
Drill down on any transaction, its status, and supporting metadata.
Payout monitoring
Configured schedules, bank transfers, and reconciliation feeds.
Unified reporting

REST APIs
REST APIs for processing, onboarding, and reporting.
SDKs
SDKs built for vertical market workflows.
Tokenization
Secure storage and reuse of payment credentials.

Pricing that fits the portfolio
Flat or Cost+ pricing
Support flat rate pricing or Cost+, where interchange passes through to merchants with a fixed markup on top, so partners tailor pricing to each portfolio rather than forcing one model on everyone.
Merchant-managed surcharging
A dynamic, merchant friendly way to recover processing costs, applied per transaction or consolidated monthly, built on CSI's established surcharging rules to keep it compliant.
Security at the core
Every transaction is protected by industry leading standards.
PCI DSS Level 1 Service Provider, v4.0.1
Independently assessed by a QSA, the highest standard in the industry.
End to end encryption and advanced tokenization
Real time fraud detection at every layer
99.9% uptime SLA
Shared responsibility model
CSIPay manages gateway and infrastructure security. Partners and merchants maintain compliance in their own environments.
Live today, expanding
United States
Card present, card not present, and ACH.
Canada

Gateway ownership is the difference. Because CSIPay owns and operates its own gateway, features are prioritized for the verticals Constellation operating companies serve, not for a horizontal platform serving everyone.
