Empowering New York Financial Software Platforms for 25 Years

Building payment processing into financial or accounting software shouldn’t require months of development or compliance expertise. Your customers expect to manage invoices, collect payments, and reconcile transactions within your platform, but traditional payment gateways force them to external pages or separate systems.

E-Complish’s ISV payment platform eliminates these friction points with technology built specifically for software integration. For 25 years, we’ve helped New York financial software vendors add payment capabilities that generate recurring revenue and increase customer lifetime value. At E-Complish, here’s what our integrated ISV solutions deliver:

Developer-Friendly API That Accelerates Time-to-Market

Launch payment features faster with comprehensive documentation, sandbox environments, and code samples in multiple languages. Our RESTful API follows industry standards and reduces development time by 40% compared to building custom payment infrastructure. On average, it takes ISVs 2-4 weeks to integrate completely.

White-Label Payment Experience

Maintain brand consistency throughout the payment journey. Customize payment pages, emails, receipts, and customer communications with your branding, colors, and messaging. Your users will never know they’re interacting with a third-party processor.

Revenue Share Programs That Create New Income Streams

Transform payment processing from a cost center into a profit center. Our revenue-sharing model lets you earn a percentage of transaction fees, creating passive income that scales with your user base. ISV partners generate an additional 15-25% revenue growth through payment monetization.

Multi-Tenant Architecture for Scalability

Support unlimited customers within your software without performance constraints. Our infrastructure handles separate merchant accounts, custom fee structures, and individual reporting for each of your clients, allowing you to manage everything through one interaction.

Automated Reconciliation That Saves Customer Time

Your users spend hours matching payments to invoices and reconciling accounts. Our system automatically syncs transaction data with your software, updating ledgers, marking invoices as paid, and generating reconciliation reports. Accounting software customers reduce month-end closing time by 60%.

Compliance and Security Handled for You

Maintain PCI-DSS Level 1 compliance without the burden falling on your development team. We handle tokenization, encryption, and secure data storage while giving you tokens to reference payment methods. Your software stays out of PCI scope, reducing compliance costs by 85%.

Ready to Embed Payments into Your Software?

Our Integrated ISV Payment Processing Solutions

Embed full-featured payment processing into your financial or accounting software through one API integration. Accept payments, automate reconciliation, and manage customer payment data without building payment infrastructure from scratch.

Payment Acceptance Solutions

Credit & Debit Card Processing

Process Visa, Mastercard, American Express, and Discover through your software interface. Real-time authorization, automated settlement, and detailed transaction reporting integrate directly into your application's workflow through simple API calls.

ACH Payment Processing

Enable bank-to-bank transfers for customers who prefer direct account payments. At 10¢ per transaction, ACH processing reduces costs for high-value payments common in B2B accounting software, while same-day ACH options ensure funds are available faster.

E-Wallets

Accept Apple Pay, Google Pay, Samsung Pay, and digital wallet payments through your platform. Tokenized transactions provide enhanced security while mobile users complete payments with biometric authentication, improving conversion rates by 32%.

E-Cash

Expand your software's reach to businesses serving unbanked customers. With E-Cash acceptance, your users can collect payments from customers who prefer cash transactions at retail locations, broadening market opportunities.

Payment Channels

Recurring Payments

Build subscription billing, recurring invoices, and automated payment collection into your software. RecurPay handles retry logic for failed payments, card expiration management, and running workflows while you maintain control over billing schedules and customer communication.

Pay-by-Text Payments

Add text-to-pay capabilities that let your users request payments via SMS. Customers receive secure payment links, complete transactions on mobile devices, and confirmations arrive automatically, accelerating accounts receivable collection by 45%.

Online Invoice Payment

Transform static invoices into interactive payment requests. Your software generates payment links that embed directly in invoices, enabling one-click payment experiences. Businesses that use integrated invoice payments reduce days sales outstanding by 38%.

Mobile Payments

Process payments from any device with mobile-optimized payment flows. Your software delivers consistent experiences across desktop, tablet, and smartphone, while our infrastructure handles device fingerprinting and mobile-specific fraud prevention.

Unique Solutions

DevConnect Payment API

Access our complete payment processing infrastructure through well-documented REST endpoints. Comprehensive guides, interactive API explorers, and dedicated technical support help your development team integrate payment acceptance, tokenization, settlement reporting, and customer management.

Instant Debit Card Funding

Push2Card technology adds real-time payout capabilities to your software. Users can disburse funds to recipients in seconds rather than days, creating competitive advantages for platforms that manage contractor payments, commission disbursements, or vendor settlements.

Electronic Signature

Streamline contract execution and payment authorization within your software. Collect legally binding e-signatures on payment agreements, subscription terms, or service contracts while maintaining full audit trails and compliance documentation.

Electronic Bill Presentment and Payment

Enable your users to send digital bills and collect payments through integrated workflows. EBPP functionality reduces paper costs, accelerates payment cycles, and provides customers with convenient online payment options directly from billing statements.

Chargeback Management

Protect your users from revenue loss with integrated dispute resolution. Our system handles chargeback evidence collection, documentation submission, and deadline tracking while achieving 90% recovery rates. Users receive notifications and can track dispute status through your software interface.

The E-Complish team helped us decrease our delinquencies by 15% and increased our online payments by 80%!! I cannot say enough about how this team works with us to analyze the problem and provide a solution. Not once did they try to upset us on a product that we did not need. I consider E-Complish a partner and consultant, not just a vendor.

E-Complish set the standard for what U.S. Auto Credit expects of its vendors. E-Complish has brought together a group of professionals that have created a partnership with U.S. Auto Credit, and provide a level of support one expects of full-time hires.

Your company came up in a discussion here the other day. They were discussing different E-Complish APIs than E-Complish offers. I told them to be nice to you because your group always does an excellent job for us. One of the other people in the discussion agreed. He said something along the lines of wanting to kick most vendors but he was very positive about working with E-Complish. Thanks, all. You are appreciated!

Since bringing E-Complish into the fold as our overall payment processor we have experienced little to no problems with processing while reducing our cost by over 30%. They are quick to respond to any question or problem that we have and do a great job of keeping informed as to the ever changing world of electronic payments. I would highly recommend E-Complish as a payment processor as they will streamline your processes and take many of the headaches out this necessary business application. I checked off the three attributes but could easily make a case that our relationship with E-Complish has been personable, they have vast expertise in this area, they produce the files in a timely manner every time, and they also operate with the highest amount of integrity. I don’t give recommendations lightly as a matter of business practice but this is one I have no problem giving. These guys do a great job!
