Frequently asked questions
What is invoice delivery software & how is it different from billing & e-invoicing software?
Billing software typically calculates charges and generates invoices. E-invoicing software focuses on the compliant electronic exchange of invoices.
Invoice delivery software manages what happens after invoice data is produced in an ERP or billing system: preparation, formatting, distribution, tracking, and archiving across customer channels and regulatory environments.
Which invoice delivery channels does Esker support?
Esker supports email, EDI, e-invoicing networks, government platforms, customer AP portals, postal mail, and fax.
Customers can also use Esker’s Electronic Invoice Presentment and Payment (EIPP) portal to access invoices and supporting documents, communicate with AR teams, and use available online payment options.
Can Esker automate submissions to customer AP portals?
Yes. Esker can automatically submit invoices and supporting documents according to each portal’s requirements, removing the need for repeated manual logins and uploads.
It also retrieves invoice statuses so teams can centrally track accepted, failed, or rejected submissions and resolve issues faster. Esker currently connects to more than 300 AP portals.
Can Esker connect invoices from multiple ERP systems?
Yes. Esker centralizes invoices from different ERP systems, entities, and regions in one invoice delivery process.
It supports SAP web services, Esker Loader, SOAP, and REST APIs, helping businesses manage complex or multi-ERP environments without maintaining a separate delivery process for each system.
Does Esker generate customer invoices?
Esker receives invoice data and documents from ERP, accounting, or billing systems. It then extracts the required information, prepares, and formats the invoice, and adds supporting documents, terms, or digital signatures when needed.
Esker Invoice Delivery is not positioned as a billing engine for calculating prices, subscriptions, or usage charges.
How can invoice delivery automation help reduce DSO?
Invoice delivery automation helps ensure that complete and accurate invoices reach customers through the correct channel and format on time.
Real-time delivery and rejection statuses also help AR and collections teams identify missing invoices, correct issues sooner, and follow up with customers using more reliable information.
