Simplify consumer use tax with Avalara and Coupa

Managing tax on purchases is often more complex than managing tax for sales. Many of the tax issues AP teams deal with start early in the purchasing process. Vendor invoices can include incorrect or missing tax, along with inconsistent treatment across locations and entities. Misalignment around taxability, inconsistencies across purchasing documents, and uncertainty about end use can lead to incorrect tax treatment, delays, and downstream rework, along with avoidable costs like overpaid sales tax to vendors, penalties, and interest.

While many issues begin earlier in the process, tax ultimately needs to be finalized and committed at the invoicing stage where accuracy and compliance matter most.

Businesses using Coupa, an AI-native total spend management platform, can now address these challenges more effectively with a new integration: the Avalara for Coupa connector integrating AvaTax for Accounts Payable. This connector was built by Avalara Certified Implementation Partner, CrossCountry Consulting.

• Tax issues can arise throughout the procure-to-pay process. Misalignment in taxability; inconsistencies across requisitions, purchase orders, and invoices; and missing or incorrect tax can create exceptions, rework, and approval delays for AP teams.
• Automate tax within Coupa workflows. The integration enables real-time tax determination across the purchasing life cycle, with validation at each stage, including requisition, purchase order, and invoice.
• Create consistent tax treatment across procure-to-pay. Applying the same tax logic across transactions reduces errors, improves visibility, and streamlines approvals.

The new connector integrates Coupa with AvaTax for Accounts Payable to deliver automated tax calculation across procurement and accounts payable workflows.

Instead of assessing tax only at the invoice stage, this integration ensures consistent tax determination across the entire procure-to-pay process, helping teams identify and correct tax errors earlier in the process while still improving accuracy at invoice approval.

This is reflected across key stages in the process:

• Estimated tax on requisitions and purchase orders for early visibility
• Final, committed tax at invoice approval for accuracy and compliance
• Transparent audit trail with tax messages and calculation details

This approach gives teams better visibility into total costs, improves accuracy at the point of invoice approval, and provides consistent tax treatment across procurement and AP.

The integrated process is designed to fit naturally into existing processes. The flow works as follows:

• 
  Coupa sends requisitions, purchase orders, and invoices to AvaTax for Accounts Payable.
  
• AvaTax for Accounts Payable calculates the appropriate tax based on maintained use tax rules and up-to-date tax content, and returns the tax amount to Coupa.
• The correct tax is applied across requisitions, purchase orders, and invoices.

Accounts payable teams are often responsible for managing tax discrepancies. Without automation, this can mean manual reviews, invoice exceptions, and delays in approvals.

By integrating AvaTax for Accounts Payable with Coupa through CrossCountry’s connector, businesses can:
 

• Improve tax accuracy and support regulatory compliance.
• Reduce invoice exceptions and downstream rework.
• Gain early visibility into total costs on purchases.
• Accelerate approvals with consistent tax treatment.
• Streamline AP processing across systems.

These benefits can be especially valuable for organizations with high purchasing volumes, multiple entities, or operations across several jurisdictions.

AvaTax for Accounts Payable is designed to automate consumer use tax compliance and help businesses manage tax on purchases more efficiently. It identifies overpayments and underpayments, applies tax logic based on rules and thresholds, and integrates with existing systems to streamline workflows.

With the addition of the Avalara for Coupa connector created and managed by CrossCountry Consulting, organizations can extend that automation directly into their procure-to-pay process — bringing together procurement, AP, and tax teams on a shared foundation.

As procurement and finance systems continue to evolve, tax needs to be part of the process, not an afterthought.

The CrossConnect connector, built by CrossCountry Consulting, helps bridge that gap by embedding tax determination into Coupa at the requisition, purchase order, and invoice approval stages, while AvaTax for Accounts Payable provides centralized control and visibility across transactions.

Together, they deliver a more connected, efficient approach to managing tax on purchases — from requisition to invoice approval, reducing risk, improving accuracy, and streamlining AP operations.
