Custom engineered Accounting & Finance integration

Avalara & HubSpot integration

Custom engineered for your business by SpotDev's accredited developers

Connect Avalara AvaTax to HubSpot so quotes and invoices created in the CRM call AvaTax for the tax on each line item at the moment they are created, and the calculated tax is written back onto the quote or invoice.

  • 2–4 weeks typical turnaround
  • £6k typical investment
  • API key

Why connect Avalara to HubSpot

HubSpot quotes and invoices apply whatever tax rate the rep selects. For a firm selling across US states, EU VAT regimes or other jurisdictions, that rate is a guess until finance checks it.

  • Rates and product taxability change, and nobody updates the HubSpot tax options to match
  • Finance re-checks every quote outside HubSpot before it can be sent, which slows the sales cycle it was meant to speed up
  • Exempt customers are handled by memory rather than by certificate
  • A quote accepted at the wrong tax becomes a credit note and a re-issue later

What you can do with Avalara and HubSpot

The integration calls AvaTax's CreateTransaction endpoint from HubSpot and writes the result back to the quote or invoice.

  • When a rep creates or edits a quote, each line item is sent to AvaTax with the customer's address and the mapped tax code, and the returned tax is written to the line and the quote total
  • Invoices generated in HubSpot follow the same path, so the figure finance sees matches what the customer was quoted
  • Products in HubSpot are mapped once to Avalara tax codes, and exempt customers are flagged on the company so AvaTax applies the exemption
  • Transactions can be committed in AvaTax when the invoice is issued, so Avalara's records match HubSpot's

Avalara & HubSpot integration: FAQs

Does Avalara have an API that HubSpot can use?
Yes. AvaTax REST v2 exposes endpoints including CreateTransaction, CommitTransaction, VoidTransaction, ResolveAddress and customer and certificate management. It authenticates with HTTP Basic Auth using either a username and password or an account ID and licence key.
Is there a native Avalara app for HubSpot?
Not from Avalara or HubSpot. A third-party app, Sales Tax Powered by AvaTax by Taxiom, is on the HubSpot App Marketplace and calculates tax on HubSpot quotes, invoices and subscriptions with VAT support. We build custom when you need your own trigger rules, multi-entity Avalara accounts or write-back into accounting.
Does this cover UK VAT and other jurisdictions, or only US sales tax?
Whichever jurisdictions your Avalara account is configured for. The integration passes the customer's address and product tax codes. AvaTax decides the rate.
How long does an Avalara HubSpot integration take and what does it cost?
Typically 2–4 weeks and from £6k. The scoping questions are how many products need tax codes, whether you invoice from HubSpot as well as quote, and whether transactions should be committed in AvaTax.
