Numeral vs Avalara is a choice between two pricing models. Numeral bills each return it files. Avalara bills each state you file in, with unlimited returns. Below, we show what each costs at 3, 5 and 10 states and what each leaves to your team. We also cover Shopify stores, where Shopify's automated filing ends with December 2026 sales.

What Numeral and Avalara cost at 3, 5 and 10 states

For a single state, Numeral costs less if you file quarterly or annually. Avalara's annual price costs less if you file monthly. Across all your states, Avalara only wins when nearly all of them file monthly.

How we calculated this. These are list prices in US dollars, checked November 5, 2026. For Numeral, we multiplied $75 by the number of returns, counting one return per state for each filing period. Numeral charges "per return required in that state", so a state where you file separate local returns costs more. Avalara's returns are unlimited. For Avalara billed annually, we multiplied $799 by the number of states, with a minimum of 3. Billed monthly, Avalara Core is $79 a month for 12 months, or $948 per state a year, again for at least 3 states. Core + SST is $699 per state outside SST, and $0 in SST states for sellers who qualify. Avalara's page doesn't say whether you can buy this plan if none of your states is in SST. Its page is also inconsistent on billing. The intro describes $69 a month as "billed annually", but the plan card and FAQ show $69 a month or $699 a year, so confirm on your quote. Numeral Enterprise and Avalara's $50 million+ plans have custom prices, so they're not shown. The break-even points below divide Avalara's yearly price per state by Numeral's price per return: $699 ÷ $75 on Core + SST, and $799 ÷ $75 on Core.Sources: Avalara+2AvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026NumeralNumeral pricingnumeral.com/pricingChecked Nov 5, 2026AvalaraAvalara pricing informationavalara.com/us/en/products/pricing.htmlFirst checked Sep 17, 2026 · Last checked Nov 6, 2026

• The break-even is about 9.3 to 10.7 returns a year in each state. Below that, Numeral costs less. Above it, Avalara does. A state you file monthly (12 returns) costs $900 a year on Numeral. On Avalara's annual prices, it costs $699 or $799. A quarterly state costs $300 on Numeral, and an annual one costs $75.Sources: Avalara+1AvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026NumeralNumeral pricingnumeral.com/pricingChecked Nov 5, 2026
• For all your states together, look at the average number of returns per state. Avalara Core, billed annually, costs less once you have at least 3 states and average more than about 10.7 returns per state. Core + SST costs less from about 9.3. Between those two averages, only Core + SST beats Numeral. If your other states file quarterly, Core + SST wins when about 2 in 3 states file monthly. Core needs about 5 in 6. With 10 monthly states, Avalara costs $1,010 (Core) to $2,010 (Core + SST) a year less than Numeral. With 6 monthly and 4 quarterly states (88 returns, 8.8 per state), Numeral costs $6,600, against $6,990 or $7,990 on Avalara. With 4 monthly and 6 quarterly (about 7 per state), Numeral costs $1,590 to $2,590 less.Source: AvalaraAvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026
• Avalara Core billed monthly doesn't beat Numeral at list price. At $948 per state a year, it costs more than Numeral even for a state with 12 monthly returns ($900). Core + SST billed monthly comes to $828 a year ($69 a month for 12 months), which is under $900. Either way, paying Avalara annually is cheaper.Source: AvalaraAvalaraAvalara pricing informationavalara.com/us/en/products/pricing.htmlFirst checked Sep 17, 2026 · Last checked Nov 6, 2026
• The 3-state minimum hurts if you sell in only one or two states. Core Compliance costs $2,397 a year even for one or two states. Core + SST has no minimum. One monthly state would cost $699 there, against Numeral's $900. But Avalara's page doesn't say whether you can buy Core + SST if none of your states is in SST.Source: AvalaraAvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026
• SST states change the answer. On Core + SST, Avalara says qualifying sellers pay "$0 for participating SST states". Avalara counts 24 SST member and associate states, plus Pennsylvania. Say 5 of your 10 monthly states are SST states and you qualify. Avalara would cost $3,495 (5 states at $699), against Numeral's $9,000. Avalara says most remote sellers qualify if they have economic nexus but no significant physical presence in a state.
• Registration adds to the first year. Numeral charges $150 per state, so 10 states add $1,500. Avalara includes registration in SST states on Core + SST. Elsewhere, it's a separate service. Avalara's products pricing page lists it at $403 per location. If each state counts as one location, 10 states add $4,030. Avalara says its registration service pays state-level registration fees for you, except fees for forms you file yourself. Numeral's help center says state registration or renewal fees are "separate from Numeral's service fees".Sources: Numeral+1NumeralNumeral pricingnumeral.com/pricingChecked Nov 5, 2026AvalaraAvalara pricing informationavalara.com/us/en/products/pricing.htmlFirst checked Sep 17, 2026 · Last checked Nov 6, 2026

Cost is only part of the Avalara vs Numeral decision. Both vendors file your returns and pay the states. They differ in how much work they leave to your team: registrations, state mail, contracts and setup.

Published price (Nov 5, 2026)$75 per return, plus a one-time $150 per state for registration, on a plan Numeral calls Professional. There's no setup fee for standard US filings.

Who filesNumeral's own team ("Numeral does not outsource filings"). You can let it file automatically (Autofile) or review and approve each return in your dashboard. Numeral's comparison page says "a dedicated U.S.-based tax expert also reviews all returns before submission."

Registrations and noticesNumeral registers you for $150 per state (it calls this Autoregister). Professional lists a "virtual mailbox for tax mail monitoring". Numeral's help center says every notice that reaches it "is reviewed and triaged by our team". Numeral's homepage says "we scan, read, and respond to all your sales tax mail", but doesn't name a plan. Its help center was asked whether Numeral responds to the state for you. Its answer: "Generally no — as with audits, you remain the state's main point of contact for a notice, and we prepare what you need to respond."

Where it beats Avalara

there's no state minimum (Avalara Core Compliance requires 3). Standard accounts are "month-to-month with no required contract", while Avalara's pricing page doesn't state its contract length. Numeral says you can cancel "at any time without penalty". It guarantees returns are "filed on time, or we'll pay your penalties and interest charges". Its Accuracy Guarantee also covers penalties and interest if an inaccurate filing leads to an audit. That cover is capped at 2x what you paid Numeral over the prior 12 months, and conditions apply.Sources: Avalara+1AvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026NumeralNumeral guaranteenumeral.com/legal/guaranteeFirst checked Nov 5, 2026 · Last checked Nov 13, 2026

Avalara

Avalara is the per-state option. You pay one yearly price per state. Returns are unlimited, and the base plan includes notice management.

Numeral vs Avalara for Shopify stores

On Shopify, the two do different jobs. Avalara can replace the tax calculation at checkout and then file. Numeral leaves calculation to Shopify Tax and files the returns.

• Shopify's automated filing is ending. It's closed to new sign-ups and covers sales only through December 31, 2026. Zamp's Shopify page summarizes this, with links to Shopify's notices. Returns for later sales need another filer.Source: ZampZampZamp for Shopifyzamp.com/for/shopifyChecked Nov 5, 2026
• Avalara works on every Shopify plan. Avalara says it is "one of Shopify's select tax partners built directly into Shopify checkout" and supports Basic, Advanced, Plus and Enterprise. Collecting exemption certificates inside Shopify is for Plus stores. Its app listing shows plans "starting at $699/state/year".
• App Store ratings (Nov 5, 2026): Numeral Sales Tax has a 4.5 rating from 140 reviews. Avalara Tax Compliance has one review, too few to tell you anything.

If you're happy with how Shopify Tax calculates, choose on filing cost and service, using the cost table above. If you want your tax vendor to calculate tax in checkout, choose Avalara.

• Nearly all your states file monthly (more than about 9 to 11 returns a year in each state) and you want a published per-state price: Avalara, billed annually.

Switching between Avalara and Numeral

Your state accounts belong to you, so a switch either way is mostly timing and paperwork.

1. Pick the last period the old vendor files. If you're leaving Avalara, line it up with the end of the term on your order form. Numeral bills as it files, so there's no prepaid period to use up. The new vendor files the next period.
2. Turn off filing in the old tool for every period the new one will file, so nothing is filed twice.
3. Check your term. Avalara's pricing page shows monthly and annual billing but not the contract length, so read your order form before you give notice. Numeral's standard accounts are month-to-month.
4. List registrations, filing frequencies and portal logins. Your state permits stay yours when you change vendors. The new vendor needs the account numbers and how often you file in each state.
5. Export exemption certificates from the old tool for exempt and wholesale customers, and load them into the new one. Numeral's first 50 are free; Avalara Core includes exemption management.Source: NumeralNumeralNumeral pricingnumeral.com/pricingChecked Nov 5, 2026

Numeral vs Avalara: FAQs

Is Numeral cheaper than Avalara?

It depends on how often you file. For a single state, Numeral costs less if you file quarterly ($300 a year) or annually ($75). For a monthly state, Avalara's annual prices cost less: $699 on Core + SST or $799 on Core, against Numeral's $900. Across all your states, Avalara costs less only when you average more than about 9.3 returns per state (Core + SST) or 10.7 (Core). That means filing monthly in nearly every state. Core has a 3-state minimum, so one or two quarterly or annual states cost less on Numeral. If you have one or two monthly states, ask Avalara whether you can buy Core + SST.Sources: Avalara+1AvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026NumeralNumeral pricingnumeral.com/pricingChecked Nov 5, 2026

Which is better for a Shopify store?

Avalara calculates tax inside Shopify checkout and files. Numeral files after Shopify Tax calculates. Shopify's automated filing covers sales only through December 31, 2026, so stores using it need another filer for later returns. The cost table above applies to both.

Do Numeral and Avalara handle state notices?

Avalara Core lists "tax notice management", and its SST plan adds audit liaison support. Numeral Professional lists a virtual mailbox for tax mail monitoring. Numeral's homepage says it responds to tax mail, but doesn't name a plan. Its help center says you usually stay the state's main point of contact, and Numeral prepares what you need to respond. Ask each vendor which notices it answers for you.

What does sales tax registration cost with each?

Numeral charges a one-time $150 per state. Avalara includes registration in SST states on Core + SST. In other states it's a separate service, listed at $403 per location on Avalara's products pricing page. Avalara says that service pays state-level registration fees for you, except fees for forms you file yourself. Numeral's help center says state registration or renewal fees are separate from its service fees.Sources: Numeral+1NumeralNumeral pricingnumeral.com/pricingChecked Nov 5, 2026AvalaraAvalara pricing informationavalara.com/us/en/products/pricing.htmlFirst checked Sep 17, 2026 · Last checked Nov 6, 2026

Do I need a contract?

Not with Numeral. Standard accounts are month-to-month and billed as returns are filed. Annual or multi-year contracts are optional. Avalara prices per state, billed monthly or annually, and its pricing page doesn't state the contract length. Annual billing saves about 15%, so read the term on your order form.Source: AvalaraAvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked Nov 5, 2026
