TL;DR

• Kintsugi Free costs $0 and covers exposure monitoring, but it does not include filing or remittance.

• Starter costs $75 per US filing or registration, according to Kintsugi’s published pricing. Monthly filing in 10 states would cost $750 per month before registration fees or add-ons.

• Premium uses custom pricing and offers volume discounts. Kintsugi requires buyers to contact sales for a quote.

• Taxwire charges $150 per state registration and $100 per return, with filing and remittance included in that flat, volume-tiered pricing. Buyers can compare those set per-action rates with Kintsugi Starter’s $75 per-filing cost, which increases with filing frequency and state count.

What are Kintsugi's pricing tiers?

Free

Kintsugi’s Free tier costs $0 per month and monitors tax exposure without filing returns or remitting tax. According to Kintsugi’s published pricing, the tier tracks physical and economic nexus across the US and more than 100 countries. It also audits historical liability, sends threshold alerts, categorizes products, validates addresses, and accepts CSV transaction imports. No-code connections support platforms such as Shopify and Stripe.

Starter

Starter adds registrations, filings, and remittance for $75 per filing or registration in the US. The QuickBooks App Store listing independently confirms that price. Kintsugi charges for each action rather than applying a flat monthly subscription, so your cost depends on filing frequency and the number of states where you have nexus.

For example, a company filing monthly in 10 states would pay $750 each month for filings. The annual filing cost would reach $9,000 before registration fees, amendments, voluntary disclosure work, or other added services. States with quarterly or annual schedules would lower the total, while additional monthly states would raise it.

Starter also supports automatic registration and deregistration where available. The tier includes refunds and amendments, basic exemption certificate management, a virtual mailbox for state notices, onboarding help, and live chat. Kintsugi claims a same-day human response for support requests.

Premium

Premium uses custom pricing for companies with multiple entities, international obligations, or high transaction volumes. Kintsugi advertises flat rates and volume discounts but does not publish the underlying price tiers.

The Premium package adds multi-country compliance and real-time invoice calculations through ERP connections such as QuickBooks, NetSuite, and Microsoft Dynamics 365. It also covers back filings with voluntary disclosure options, expanded exemption certificate management, custom reporting, API access, single sign-on, and dedicated account support. Buyers must contact sales to learn how transaction volume, entity count, country coverage, and ERP requirements affect the quote.

What pricing does Kintsugi not publish?

Kintsugi does not publish a base price, usage threshold, or standard fee schedule for Premium. Its pricing page says volume discounts apply, but buyers must contact sales to learn how transaction volume, entity count, countries, and support requirements affect the quote. The page also leaves fees for back filings, voluntary disclosure agreements, and other specialized work unspecified.

Premium gates several capabilities that larger companies may need. Kintsugi lists multi-country compliance and real-time invoice calculation through NetSuite and Microsoft Dynamics 365 under this tier. Buyers cannot evaluate those capabilities without a sales conversation, and Kintsugi does not publicly confirm certification status for the listed ERP integrations.

Kintsugi prominently promotes its funding and AI features, including Kintsugi Intelligence and the Kin assistant. Public materials provide less detail about independently verified ERP performance, multi-entity administration, and service capacity. Accounting firms and larger buyers should therefore request product demonstrations, integration documentation, certification details, service-level terms, and complete pricing before comparing a Premium quote with other platforms.

How does Kintsugi pricing compare to Avalara, TaxJar, and Taxwire?

Kintsugi’s published Starter price can look predictable at one filing, but total cost increases with filing frequency and the number of jurisdictions. The comparison below shows how each provider structures pricing and compliance work.

Buyers should compare annual cost using their expected return count. Kintsugi Starter would charge $9,000 annually for ten monthly state filings, before registrations, amendments, or separately quoted Premium services.

Where is Kintsugi's product depth unconfirmed?

Kintsugi’s published pricing page features customer testimonials drawn from smaller e-commerce and direct-to-consumer businesses. Those testimonials help establish Kintsugi’s served market, but they provide limited evidence for accounting firms or larger companies managing several entities and tax environments.

Kintsugi promotes AI features such as automated product categorization and its Kin assistant. However, buyers with more complex requirements need to assess the underlying integrations and service coverage rather than the AI positioning. Kintsugi places multi-entity support and real-time calculation through NetSuite or Microsoft Dynamics 365 in its custom-priced Premium tier. Its public materials do not confirm whether those ERP connections carry vendor certification.

Accounting firms face added uncertainty because they must evaluate the platform across multiple clients rather than one e-commerce store. A connection that works for Shopify transactions may not establish that Kintsugi can handle several legal entities, varied accounting systems, or higher-value filings. Firms should confirm ERP functionality, entity separation, implementation responsibilities, and support terms during the sales process.

Taxwire’s competitive comparison frames Kintsugi as an SMB-focused platform with stronger public marketing than independently verifiable product depth. Buyers should treat that assessment as Taxwire’s position, then verify Kintsugi’s capabilities through demonstrations, technical documentation, and contract terms.

What are the best alternatives to Kintsugi?

Kintsugi alternatives differ mainly in how they price compliance work and who completes it. Buyers should compare the service model, filing responsibilities, and support for multi-client or complex accounts alongside the software fee.

Taxwire

Taxwire charges $150 per state registration and $100 per return, a flat, volume-tiered structure based on annual transaction volume rather than revenue. Filing and remittance are included in that managed-service model, so adding filing obligations does not create the same per-filing cost pattern as Kintsugi Starter's $75-per-filing rate. Pricing can change when transaction volume reaches another tier, but customers can forecast costs using the set registration and return rates instead of multiplying a filing fee by every return.

Taxwire combines its calculation engine with an in-house tax team. Tax professionals handle nexus monitoring, registrations, returns, remittance, and historical cleanup. Customers approve returns before filing, which gives finance staff a defined review point without requiring them to prepare each return internally.

Taxwire also builds and maintains its own tax engine rather than licensing rate data from another provider. The engine calculates tax at the transaction level, while the same managed-service operation uses transaction data for filing and remittance. Keeping those functions together reduces the handoffs that can occur when software calculates tax but an outside accountant prepares the returns.

Accounting firms can use Taxwire when client volume makes filing work difficult to absorb internally. The managed-service structure places recurring compliance work with Taxwire’s in-house team rather than sending it back to the accounting firm. Buyers evaluating multi-state operations, historical exposure, or higher-value accounts may also benefit from access to tax professionals who can investigate obligations beyond routine e-commerce filings.

Avalara

Avalara fits larger companies that need an established sales tax platform with broad enterprise reach. Its subscription-plus-overage model provides a contracted service allowance, then charges additional fees when usage exceeds that allowance. By comparison, Kintsugi Starter charges $75 for each US filing or registration.

Buyers should model expected transaction and filing volume carefully because Avalara's overage charges can raise the contracted price above the plan's advertised starting rate.

TaxJar

TaxJar suits smaller e-commerce sellers who want sales tax calculation and filing software within the Stripe ecosystem. Stripe owns TaxJar, and TaxJar's published pricing sets plan tiers with included AutoFile credits, which can make the product a natural option for sellers already using Stripe for payments and transaction data.

Kintsugi separates free exposure monitoring from paid compliance. Its Starter tier charges $75 for each US filing or registration, so costs rise with filing frequency and state count. When comparing TaxJar with Kintsugi, review TaxJar’s current subscription limits and filing charges against your transaction volume. Also confirm which returns require separate fees. Kintsugi may suit sellers that want free nexus monitoring before purchasing filing support, while TaxJar may appeal to sellers seeking a software-focused option tied to an established payments provider.

• What does Kintsugi Premium cost? Kintsugi does not publish a price for Premium. The company provides a custom quote and states that volume discounts apply. Buyers must contact sales to price multi-entity, international, or ERP-related needs.

• Does Kintsugi Free include filing? Kintsugi Free does not include registrations, returns, or remittance. The tier monitors nexus exposure and provides tools for risk assessment, product categorization, and transaction imports. You must upgrade to Starter or Premium for filing services.

• How does Kintsugi pricing compare with Taxwire's flat-fee model? Kintsugi Starter charges $75 for each filing or registration, so the total depends on your filing obligations.

Taxwire also assigns its in-house tax team to manage filing and remittance.
