Anrok vs Kintsugi: which sales tax platform fits your business?

Anrok and Kintsugi both handle calculation, filing, and remittance, but they are built for different businesses and come with very different pricing models, support setups, and limitations.

They also charge in completely different ways. Anrok bills $100 per market per month. Kintsugi bills $75 per filing and $75 per registration. For teams comparing the two, that difference shows up as you enter new states, not on day one.

This guide breaks down Anrok vs Kintsugi across features, pricing, support, and integrations, including what a year of filing costs for a real SaaS business and a real ecommerce seller.

We’ll also compare both to TaxCloud, which is built specifically for mid-market brands and is one of the few Certified Service Providers under the Streamlined Sales Tax program that registers and files in 24 states at $0 for eligible remote sellers.

Anrok vs Kintsugi vs TaxCloud: feature comparison

One note on marketplace filing models: if your business relies on returns being filed on a marketplace’s behalf, confirm with Kintsugi directly that they support that arrangement before you commit.

What is Anrok?

Anrok is built for high-growth SaaS companies with global teams. It tracks the nexus your employees create, so a remote hire in a new state doesn’t go unnoticed. It covers VAT in more than 100 countries, and it calculates tax in real time through its API and billing integrations.

Pricing is per market. The standard Starter costs $100 per market per month, and the “Anrok for eCommerce” Starter costs $50 per market per month. On Shopify, tax at checkout is calculated by Shopify Tax, and Anrok then rechecks those amounts.

Anrok clearly wants the ecommerce market. It built the dedicated tier and runs an agency partner program. So far, though, there’s little sign merchants have arrived: its Shopify App Store listing shows zero reviews as of August 2026.

What is Kintsugi?

Kintsugi is a newer platform with a strong interface and fast automated liability assessment. It offers three tiers. The Free tier covers monitoring, the Starter tier charges $75 for each filing or registration, and the Premium tier is custom-priced with volume discounts. A virtual mailbox for state notices is included from Starter.

One question worth asking before you buy is about the Vertex relationship. Kintsugi’s own comparison page describes the platform as “Powered by Vertex,” and Vertex’s FY2025 annual report confirms the relationship goes beyond a technology license: Vertex also invested in Kintsugi and sends smaller prospects, the businesses below its enterprise focus, to Kintsugi’s sales team.

The details come from Vertex’s announcement on April 30, 2025. Vertex paid $15 million for a 10% stake in Kintsugi, took a seat on its board, and the two companies share intellectual property. None of that is disqualifying. But add it up and the picture changes.

The calculation engine belongs to Vertex, Vertex holds a board seat and a tenth of the company, the technology is shared, and a stream of Kintsugi’s customers arrives through Vertex’s funnel.

A buyer choosing Kintsugi to get away from legacy vendors is still, in most of the ways that matter, inside one’s orbit.

What is TaxCloud?

TaxCloud is a sales tax compliance solution for growing mid-market businesses that combines powerful automation with real human support. It calculates sales tax accurately, tracks nexus thresholds, manages state registrations, and files returns across multiple states, platforms, and channels, with Canadian sales tax handled through the Shopify integration and the TaxCloud API.

As one of the few SST Certified Service Providers, TaxCloud registers and files at $0 in 24 SST states for eligible remote sellers. US-based support from real people who actually understand sales tax is included on both Starter and Premium: when a state notice arrives, you talk to someone who knows your account, not a ticketing queue.

For SaaS billing, Chargebee real-time calculation is a Premium feature, and the new Stripe integration connects TaxCloud as the compliance layer downstream of Stripe Tax, with real-time calculation available through the tax calculation API. Shopify, WooCommerce, and BigCommerce carry the ecommerce side.

What is the SST program, and why does it decide this comparison?

SST is a program run by the Streamlined Sales Tax Governing Board, an organization of member states that standardized their sales tax rules to make multi-state compliance manageable. Twenty-four states participate.

Here is what makes the program valuable. Eligible remote sellers who go through a Certified Service Provider can register and file in member states at no cost, because the states pay the CSP directly for the work.

A vendor can’t simply add SST certification to its roadmap. It’s granted by the Governing Board, and only several providers currently hold it, per the Board’s certified service providers list: TaxCloud, Avalara, Sovos, AccurateTax, and Avior.

Anrok and Kintsugi do not appear on that list, which is why every filing in an SST state costs full price on either platform. To get the program’s benefit at all, you have to work with a certified provider, and the CSP also becomes your primary contact if an SST state audits you.

In practice, “$0 filings” means the SST-eligible share of your footprint simply stops generating filing costs. The pricing scenarios below show what that does to a real bill.

Pricing: Anrok vs Kintsugi vs TaxCloud

The three platforms charge in fundamentally different ways, and that difference matters more than any single price.

Anrok charges per active market per month, with filings included, so your bill depends on how many states you’re in. Kintsugi charges $75 per filing, so your bill depends on how often you file.

TaxCloud charges a subscription based on order volume (Starter from $19/month, Premium from $79/month) plus $39 per return pay-as-you-go, falling as low as $20 at volume, and eligible SST filings cost $0 and don’t count against any allotment.

A SaaS company and an ecommerce seller have very different filing footprints, so here are two scenarios that demonstrate what the cost is likely to be filing with different providers.

Scenario 1: a SaaS company filing in 8 states

Picture a SaaS company that files in New York, Texas, Pennsylvania, Massachusetts, Connecticut, Arizona, Ohio, and Washington. Two of those states, Ohio and Washington, are SST members. Because SaaS transaction volume is relatively low, most of these returns are quarterly rather than monthly, which comes to 32 returns a year.

One thing to know before applying this to your own business: SaaS taxability varies by state, so having nexus in a state doesn’t automatically mean you owe a return there. This example assumes all eight states produce returns.

Scenario 2: an ecommerce seller filing in 12 states, monthly in the big ones

Now take an ecommerce seller filing in twelve states: California, Texas, New York, Florida, Illinois, and Pennsylvania monthly, plus Georgia, North Carolina, Ohio, Michigan, Wisconsin, and Washington quarterly.

The six quarterly states are all SST members. The six monthly ones are not, because the biggest states a growing seller enters first aren’t in the program. That comes to 96 returns a year.

Both tables show filing costs only. TaxCloud plans start at $19/month, Anrok’s per-market fee includes the platform, and Kintsugi’s Starter has no separate platform fee. A seller at Scenario 2’s order volume lands on the Premium plan, which starts at $79/month and is priced by order volume.

The two tables also show something no vendor’s pricing page spells out. Anrok charges per market whether you file twelve times a year or four. Kintsugi and TaxCloud charge per filing.

That makes filing frequency the thing that decides which of the two costs more, and the swing is large: file quarterly and Kintsugi’s bill falls by roughly two thirds while Anrok’s doesn’t move at all.

File monthly and Kintsugi’s per-filing charges catch up with Anrok’s per-market fee. TaxCloud comes in lowest in both examples because filings in SST states cost nothing.

One more Anrok pricing detail matters if you sell in Canada. Anrok’s pricing FAQ counts Canadian federal GST/HST, British Columbia, Manitoba, Saskatchewan, and Quebec as separate markets, each billed at the per-market rate.

A seller covering the US and Canada can take on five markets under Anrok’s definition before adding a single US state.

Support

Support comparisons usually come down to counting channels: who has chat, who has phone, who answers on weekends. But when a state notice lands on your desk, the questions that actually matter are different. Who picks up? Do they already know your account? And who takes responsibility for getting it resolved?

TaxCloud’s answer is that support comes from US-based employees who know sales tax and know your account, and it’s included on both plans. When a filing deadline is close or a state letter arrives, you’re talking to a person who is accountable for the outcome, not opening a ticket into a queue.

Anrok’s FAQ describes its support as US-based, with a dedicated team that helps customers through onboarding. Priority support is reserved for the Custom plan, so businesses on the Starter tiers wait in the standard line.

Kintsugi advertises 24/7 chat from its Starter tier, with same-day human responses, and its G2 support score of 9.2 is its best-rated category. Though customers rate Kintsugi’s support highly, two details are worth knowing before you weigh it.

The chat experience is AI-powered on every paid plan, as our audit protection comparison notes, so the first responder is usually software rather than a person. And SLA-backed support appears on Kintsugi’s pricing page as a Premium feature, which means that below Premium, there’s no committed service level: same-day responses are advertised, not promised.

Integrations

Anrok lists more than 40 integrations, and the list tells you who the product is for: the connections cluster around billing, ERP, and HR systems, with Stripe, NetSuite, Salesforce, Zuora, Chargebee, QuickBooks, and Workday among the names. Its real-time API calculation is genuine, including at the moment an invoice is created. Custom API work goes through Anrok’s own integrations team, by their own description. On the ecommerce side, the dedicated tier connects Shopify and WooCommerce, and on Shopify, tax at checkout is calculated by Shopify Tax, with Anrok rechecking those amounts.

Kintsugi names its no-code integrations on its pricing page: Shopify, Stripe, Chargebee, and BigCommerce, with NetSuite and Dynamics 365 connections reserved for Premium. One practical note if Shopify matters to you: Kintsugi’s app is live on the App Store as of July 29, 2026, after a period earlier in the summer when it wasn’t available, so it’s worth checking the listing directly when you evaluate.

TaxCloud runs real-time integrations on Premium with BigCommerce, WooCommerce, QuickBooks Online, Chargebee, Magento, Adobe Commerce, Miva, Odoo, and AcctVantage. Shopify and Stripe connect differently, as data-import integrations: Shopify Tax and Stripe Tax calculate tax at checkout, and TaxCloud handles nexus tracking, filing, remittance, and audit support from there. The tax calculation API comes with sandbox access in the 30-day trial.

For a mid-market seller working across channels in the US and Canada, TaxCloud covers the platforms that matter. If your stack is global SaaS built on Zuora and Workday, Anrok is the more natural fit, and that’s a fair outcome.

Reviews

While a platform might have what you’re looking for on paper, reviews tell you what it’s like to use day to day. Here’s what customers say about Anrok, Kintsugi, and TaxCloud.

Anrok

Anrok holds a 4.4 rating on G2 from 287 reviews, mostly from mid-market companies, with praise for its tax automation and quick implementation. Anrok reviews also note that the platform can be technically complex, and even developers say they face challenges making sure it’s working properly:

Kintsugi

Kintsugi holds a 4.5 rating on G2 from 33 reviews, almost all from small businesses, and its 9.2 quality-of-support score is its strongest category. The interface earns the most consistent praise, though not every experience is smooth:

TaxCloud

More than 2,000 businesses use TaxCloud to manage their sales tax. These TaxCloud reviews highlight what they love:

Which platform fits your business?

When it comes to what platform will be best for your business, the honest answer depends on what kind of business you run, so here is each platform’s best fit.

Who is Anrok best for?

Anrok is the right fit for high-growth SaaS companies with employees around the world. Its workforce nexus tracking and VAT coverage in more than 100 countries solve problems the other two platforms don’t try to solve. The trade-off is the pricing model: $100 per market per month, in every state, whether you file monthly or quarterly.

Who is Kintsugi best for?

Kintsugi suits small businesses that want a clean interface and fast setup, and whose filing volume is low enough that $75 per return stays manageable. Before committing, buyers should understand that the calculation engine, a board seat, and a 10% stake sit with Vertex, and that support below Premium comes without a committed service level.

Who is TaxCloud best for?

TaxCloud is built for mid-market ecommerce and SaaS businesses selling in the US and Canada. It holds the SST cost advantage neither competitor can match, and it includes US-based support from real people who actually understand sales tax on both plans.

Verdict: Anrok vs Kintsugi vs TaxCloud

The two scenarios above tell the story. The SaaS company paid $936 a year with TaxCloud against $2,400 with Kintsugi and $9,600 with Anrok. The ecommerce seller paid $2,808 against $7,200 with either competitor.

The difference is the SST program.

TaxCloud registers and files at $0 in 24 states for eligible remote sellers, and neither Anrok nor Kintsugi participates.

The other difference is people: when a state notice arrives, you talk to someone who knows your account.
