Api quality

Calculate the right sales tax for a transaction through an API in real time — address-level (rooftop) accuracy, not ZIP-code approximations — fast enough to sit inside checkout C

Calculation api

An agent can read my tax posture — nexus status, registrations, accrued liability, upcoming filings — and act on it through the API or an MCP surface with scoped credentials C

Agent operations

VAT and GST are covered like US sales tax — EU OSS/IOSS, UK, Canada, Australia and beyond, with foreign registration thresholds tracked and filings supported C

Vat coverage

The product gets the hard cases right — SaaS taxability that differs by state, digital-goods rules, and bundled offerings — with the research behind each determination visible C

Saas rules

Define rules that trigger actions automatically on events G

Export all of my data in open formats and leave G

Returns are prepared, filed, and remitted automatically in every registered jurisdiction — on time, with the vendor's guarantee covering penalties if it files late C

Autofile

The product watches my economic nexus exposure — tracking sales and transaction counts against every state and country threshold and alerting me before I cross one, not after C

Threshold tracking

Prevent my data from being used to train AI models G

Self-host the core product G

Map my catalog to the vendor's tax categories — SaaS, digital goods, services, physical products — so each line item is taxed by what it is, in every jurisdiction it sells C

Tax codes

Do everything through the API that I can do in the UI G

Every calculation is reconstructable — the rate, rules, address resolution, and product category that produced each transaction's tax, retained and exportable for an audit C

Audit trail

Exemption and resale certificates are managed end to end — collected from customers, validated, stored with expiry tracking, and applied automatically at calculation time C

Certificate management

Invoices come out compliant where I sell — required VAT fields, registration numbers, and locale rules flow through to my invoicing system or are generated by the product itself C

Invoice compliance

Rate and rule changes across thousands of jurisdictions are the vendor's job — updates land automatically, are documented when they take effect, and never require me to redeploy C

Rate maintenance

Transactions from every channel can be imported — API backfills and connector syncs from other processors and storefronts — so filings cover my whole business, not just one integration C

Channel imports

Mark a customer or transaction exempt through the API — with the exemption reason carried through calculation, reporting, and the filed return C

Exempt customers

See accrued liability by jurisdiction at any moment — collected versus owed, filing-ready detail, and exports my accountant and GL can consume C

Liability reports

There are maintained integrations for my revenue stack — billing systems, payment processors, and commerce platforms feed transactions in without me building the plumbing G

Integrations

Perform bulk operations across many items at once G

B2B cross-border sales are handled correctly — VAT and tax IDs validated against official registries in real time, reverse charge applied when it should be C

Vat validation

Import my historical transactions and see where I already owe — a backdated exposure analysis with estimated liability, penalties, and interest per jurisdiction C

Exposure analysis

Marketplace sales are modeled correctly — transactions where a facilitator (Amazon, app stores) collected the tax are tracked for nexus and reporting without being double-remitted C

Marketplace rules

Read the product's source under an open license G

Registering for a sales tax permit is handled in-product — the vendor files state and local registrations on my behalf with transparent per-registration pricing and status tracking G

Registration filing

See the whole filing picture — a calendar of upcoming returns, per-filing status, the amounts remitted, and downloadable confirmations for every return submitted C

Filing visibility

The product ships its own AI for tax questions — is this product taxable in this state, why did this invoice tax this way — answering from its rule base with citations, not a generic chatbot C

Builtin ai

Choose where my data is stored (region/residency) G

Control data retention and deletion G

Opt out of telemetry and usage tracking G

Past-due exposure has a remediation path — voluntary disclosure agreements or back-filing support to clean up jurisdictions where I should have been collecting C

Remediation

Refunds and credit notes adjust tax correctly — negative amounts flow through liability, reporting, and the next filing without manual journal fixes C

Adjustments

Schedule recurring jobs or workflows G

The vendor stands behind its numbers — a documented accuracy guarantee or audit support commitment if a calculation it produced turns out wrong C

Accuracy guarantee

Version, review, and roll back my automations G
