How it works
From install to computed tax in about a minute
Sales tax tools usually mean onboarding calls and implementation fees. AutoTax is a module you install and a button you click.
Install the module
Grab AutoTax from the Odoo App Store and install it like any other module. No implementation project, no sales call.
Connect in Settings
One click in Odoo Settings links your database to AutoTax. That's the whole configuration.
Click Compute Tax
On any invoice or sales order, one click fetches the current rate for your customer's shipping address and applies it as a native Odoo tax.
Prefer zero clicks? Turn on auto-compute and AutoTax applies the right rate automatically whenever a shipping address is set.
Why AutoTax
Everything you need to charge the right tax. Nothing you don't.
Most businesses on Odoo don't need a tax compliance platform — they need correct rates on every invoice, without thinking about it.
Flat monthly price
Unlimited computations for one flat fee. The big suites meter you by transaction or order volume — your bill grows with your business. Ours doesn't.
City-level accuracy, always current
State, county, city and district rates for every US ZIP code, continuously updated as jurisdictions change them. No stale tax tables to maintain.
One click — or none
Compute Tax lives right on your invoices and sales orders. Or enable auto-compute and rates apply themselves when the shipping address is set.
Native Odoo taxes
AutoTax creates real Odoo tax records, so everything flows into Odoo's own tax report exactly the way your accountant expects.
Built only for Odoo
Not a generic connector to someone else's platform. Odoo 15 through 19 is the entire product, built by an official Odoo partner.
Cancel anytime
Month-to-month, no contract, no seat minimums, no annual lock-in unless you want the discount.
An honest comparison
The big suites are great. They're also 5–20× the price.
Avalara, TaxJar and TaxCloud sell full compliance platforms — calculation plus nexus tracking, filing and remittance. If all you need is the right rate on every invoice, you're paying for a lot of software you'll never open.
| Capability | AutoTax | Avalara AvaTax | TaxJar | TaxCloud |
|---|---|---|---|---|
| Price | $39.99/mo flat, unlimited computations | Custom quote; typically $600–6,000+/yr all-in | From $39/mo for 200 orders, scales with volume | From $79/mo for API access |
| Per-transaction fees | None, ever | Usage-based pricing | Order-volume tiers | Order-volume tiers |
| Setup | ~1 minute, self-serve | Sales process + implementation | Self-serve, third-party connector | Self-serve, third-party connector |
| Built for Odoo | Odoo is the entire product | Native connector, generic platform | Generic platform | Generic platform |
| Files returns for you | No — built for teams that file their own | Yes, $42–54 per return | AutoFile, $50–55 per filing | Yes, included in SST member states |
Competitor pricing from published price lists and 2026 pricing reviews as of August 2026; actual quotes vary by volume and features. We'd rather you compare than take our word for it.
When you actually need one of the big suites
AutoTax computes rates — it doesn't track economic nexus, manage exemption certificates, or file returns. If you have filing obligations across many states and want them fully automated, a platform like Avalara or TaxCloud is worth its price, and you should buy one.
But if you file your own returns — or your accountant does — and what you need is the correct rate on every Odoo invoice with zero maintenance, that's exactly the product we built. One thing, done well, at a price that stays flat.
