AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
This listing bills through a contract for automated tax calculation. You commit to Avalara AvaTax, which is priced per unit based on the transaction volume your business processes. The Overage per contract dimension covers usage beyond your committed volume. It also bills per unit, so you pay for additional transactions that exceed your contract amount. The two dimensions work together: your base commitment sets your included volume, and overage charges apply only when you go past it. Pricing scales with the number of transactions you run.
Top-of-mind questions for buyers
What counts as one unit for Avalara AvaTax billing?
A unit maps to a sales transaction that AvaTax processes for tax calculation. Your billed volume reflects the number of transactions your business runs through the system. Cost scales with transaction count, so higher monthly transaction volume increases the units you consume.
What happens when my transaction volume passes my committed contract amount?
Transactions within your committed volume draw from your Avalara AvaTax contract. Once you exceed that amount, the Overage per contract dimension applies. Overage bills per unit for each transaction beyond your commitment. You only pay overage when you pass your included volume.
Which factors influence how many transactions I process each month?
Transaction volume depends on your sales activity, the number of business applications integrated with the solution, and the states or jurisdictions where you collect and remit sales tax. More sales and more jurisdictions raise your processed transaction count, which drives the units you consume.
