OnlineCheckWriter.com - Powered by Zil Money Launches ACH API to Help Software Platforms Automate Business Payments and Direct Deposits

The new ACH API enables software platforms to send ACH payments, process direct deposits, and support Same Day ACH through one developer integration.

TYLER, TX, USA - July 14, 2026 - OnlineCheckWriter.com - Powered by Zil Money today announced the launch of its ACH API, giving software platforms a faster way to embed ACH payments, direct deposits, and Same Day ACH into their own applications. Instead of building and maintaining a direct bank integration, developers can connect to one API to automate business payments from within the software their customers already use.

Businesses process thousands of ACH transactions every day for payroll, vendor payments, recurring billing, and fund transfers. Many still rely on manual NACHA file uploads, separate banking portals, and spreadsheets to approve, track, and reconcile payments. These disconnected workflows slow operations, increase administrative work, and make it harder to scale.

For software companies, the challenge is even greater. Building an ACH payment system requires engineering resources, banking connections, NACHA file formatting, and ongoing maintenance. Those requirements can delay product launches and pull development teams away from building core features.

The OnlineCheckWriter.com - Powered by Zil Money ACH API removes that complexity by providing one integration for ACH payments, direct deposits, recurring transfers, and batch payment processing. Developers can initiate payments directly from their applications without sending users to an external banking portal.

The API supports individual ACH payments, recurring transactions, payroll processing, and large vendor payment batches through the same set of endpoints. Businesses that need faster payment delivery can also use Same Day ACH when transactions are submitted before the applicable processing cutoff.

The API is designed for software platforms across many industries.

Payroll providers can automate employee direct deposits from within their own applications. Property management platforms can collect rent and pay property owners and vendors without switching between systems. Marketplaces can send payouts to sellers and contractors, while lending platforms can disburse loans and collect repayments through the same integration. Insurance platforms can send claim payments directly to policyholders' bank accounts.

The ACH API also supports businesses that process recurring or high-volume payments, including construction companies paying subcontractors, franchise organizations distributing royalty payments, healthcare providers, accounting platforms, and subscription-based businesses.

As payments move through the ACH network, applications automatically receive status updates, helping businesses track transactions from initiation through settlement or return. The API also notifies platforms when financial institutions report changes to recipient account information, helping businesses maintain accurate payment records.

Security and compliance are built into the platform. Payment information is encrypted during transmission and while stored, and transactions are processed using NACHA-compliant workflows. This allows businesses to integrate ACH payments while maintaining secure payment operations.

"Businesses want payments to happen inside the software they already use," said Sabeer Nelli, CEO of OnlineCheckWriter.com - Powered by Zil Money. "Our ACH API helps software platforms embed ACH payments, direct deposits, and Same Day ACH without the complexity of building and maintaining their own banking infrastructure. That allows developers to focus on creating better products instead of managing payment operations."

Embedded payments continue to become an important part of modern business software. Instead of directing customers to separate banking portals, many software providers now want to manage payment workflows within their own platforms. An integrated ACH API helps businesses reduce manual work, improve operational efficiency, and deliver a better customer experience as payment volumes grow.

The ACH API is available now. Developers can review the API documentation, request sandbox access, and begin testing their integrations before moving to production. Access is provided based on business requirements and expected payment volume.

Businesses interested in integrating the ACH API can contact the OnlineCheckWriter.com - Powered by Zil Money integration team to request sandbox credentials, discuss implementation requirements, and receive pricing information.
