Case Study : Open Cart Integration


Our client is a privately-held company developing cloud-based sales tax and compliance systems and is one of just six Certified Service Providers available to retailers.


Our client wants to reduce all audit risks with cloud-based sales tax services that make it simple to calculate rates, manage exemption certificates, file forms, and remit payments for their end customers. The number of end clients and their interfaces increase over a short period of time and it is important for the client to ensure that the volume of interfaces, integrations and transactions are accurate, seamless, and transparent with 100+ existing ERP, accounting, ecommerce and Retail POS systems. The client engaged Divensi to

  • Get intelligent sales tax calculations in its own software
  • Speed up the exemption certificate process
  • Ensure timely filing and remittance
  • Meet end-to-end sales tax compliance


Our project manager, developers and testers are working continuously with the client’s leadership team and routinely analyzes the various industry interfaces to ensure automation of the sales tax calculations, exemption certificate management and filing, remittance and more, empowering the end customer applications to accurately calculate up-to-date tax rules and regulations that are applied in real-time to each transaction including:

  • Address validation
  • Jurisdiction assignment
  • Sourcing rules
  • Product taxability
  • Accurate calculations at the point of transaction
  • Exemption certificate management
  • On-time, every time filing and remittance of transactional sales tax liabilities
  • Boosting the value of business through accurate sales tax compliance with cloud-based services

Divensi works hand in hand with our clients across the finance, ecommerce, retail and other domains and ensures that our collaborative effort is able to give the client’s large customer base the satisfaction they need when it comes to eliminating any audit risks.


Our software development and integration lifecycle is able to provide the client and their end customers the interfaces to function accurately, efficiently, on time, and within the best possible budget. This is an on-going venture with several such integrations and we continue to develop and perfect these processes collaboratively with our clients.
