Integrations / Automation
Invoicing software integration for your online store, order system or web application
An invoicing software integration is an automated connection between an online store, order system, or web application and an invoicing platform that generates invoices and credit notes directly from transaction data. It pays off once order volume makes manual data entry slow and error-prone. The DNAVI team maps sales data to invoice fields, builds the API connection, and covers edge cases such as refunds and payment status changes.
Automated invoicing should correctly handle customer data, document numbering, payment statuses, corrections and edge cases.
Process
We map data flows and user decisions first, and only then write the API code.
Stability
We account for errors, request retries, API limits, logs and event monitoring.
Automation
Integrations should save time, reduce errors and speed up operations.
Growth
After launch, you can add more systems, statuses, rules and reports.
Benefits of invoicing integration

Frequently asked questions
Do you build integrations with external APIs?
Yes. We integrate websites, online stores and applications with payment systems, carriers, ERP, CRM, inventory, invoicing, Baselinker and other tools.

Yes. We first analyze your current code, data and process, then propose a safe implementation scope.
Do you monitor the integration after launch?
We can set up logs, error handling, notifications and ongoing technical support so that problems or API changes are addressed faster.
