Cetec ERP / Avalara Tax Integration
EFS DevOps built a cloud-hosted middleware integration between Avalara AvaTax and Cetec ERP, automating tax calculation, exemption management, and compliance while achieving Avalara certification.
The Challenge
Cetec ERP customers needed automated sales tax calculation integrated into their manufacturing workflows. Key pain points:
- Complex onboarding: Manual configuration of Avalara credentials and tax mapping for each customer
- Decentralized logging: Difficulty auditing Avalara API calls across tenants
- Compliance risk: Manual exemption management and document lifecycle tracking
- Scalability/security: Secure credential handling across a multi-tenant environment
Solution
Secure Middleware Hub
A SaaS broker connecting Cetec ERP and Avalara APIs with multi-tenant isolation, deployable on AWS/Azure/GCP.
Onboarding Wizard & UI
Step-by-step configuration: company code lookup, test connections, credential validation, and a comprehensive user guide for customer self-service.
Automated Tax Calculation & Exemption Handling
- Real-time tax determination on every Cetec transaction
- Exemption syncing — entity use codes, certificates, and discount management
- Full transaction lifecycle: freight/shipping, refunds, and credit memos
Document Lifecycle Sync & Logging
Posted and voided invoice synchronization with centralized audit logs for compliance reporting.
Field Mapping Engine
Auto-maps Cetec entities to Avalara data structures and handles the complete transaction lifecycle from quote through fulfillment.
Avalara Certification
EFS Networks completed the full Avalara certification process: demo onboarding, user guide with screenshots, demo video submission, and follow-up validation. The integration is now Avalara-certified for go-to-market.

- Removes manual sales tax calculation from Cetec manufacturing workflows
- Streamlines exemption and certificate management across all customer accounts
