AI Shopify App Cost Calculator: What a Real Stack Costs by GMV Tier (2026)

**Shopify Magic** is the AI layer Shopify quietly bundled into every plan starting in 2024 and aggressively expanded through 2025. It writes product descriptions inside the admin, drafts FAQ blocks for product pages, generates email subject lines inside Shopify Email, suggests theme copy, and powers the Sidekick admin assistant for store operations questions. It costs zero additional dollars on top of your Shopify subscription, which starts at $39/mo Basic, $105/mo Shopify, $399/mo Advanced, or $2,300/mo Plus (https://www.shopify.com/pricing). The catch is that Magic is generic — fine for a 200-SKU catalog, painful for 10K+ SKUs where you need brand-voice consistency and structured attribute extraction. For most merchants under $5M GMV, Magic is the right answer for copy.

**Klaviyo** is the gravitational center of DTC email. Its AI features — predictive lifetime value, predicted next order date, AI subject-line generation, smart send-time optimization, and the AI campaign builder — are bundled into the standard plans, not gated behind an add-on. Pricing scales with active profile count: $20/mo for 500 profiles, $45/mo at 1K, around $150/mo at 10K, $400-$700/mo at 50K-100K, and roughly $1,700/mo at 250K profiles (https://www.klaviyo.com/pricing). Above 250K it goes custom. Klaviyo's AI is not flashy, but the predictive segments meaningfully outperform rules-based ones, and the integrated SMS keeps the data in one place.

**Gorgias** is the helpdesk that owns the Shopify ecosystem because it ingests order context natively. Base plans run $10/mo Starter (50 tickets), $60/mo Basic, $360/mo Pro, and $900/mo Advanced (https://www.gorgias.com/pricing). The AI lives in the Automate add-on, which costs an additional 30% of your base plan and resolves common tickets — WISMO, returns, address changes — without human touch. At $360/mo Pro plus a $108/mo Automate add-on, you get a helpdesk that genuinely deflects 30-50% of repetitive tickets if your macros and order tags are clean. If your support team is buried in WISMO, this pays back in two months.

**Rebuy** is the personalization engine. Pro is a flat $499/mo (https://rebuyengine.com/pricing) — there is no cheaper Shopify App Store tier worth running. Rebuy powers smart cart upsells, post-purchase one-click offers, AI product recommendations across PDPs and the cart, and checkout extensions on Shopify Plus. The math works if you do $5M+ GMV: a 3-5% AOV lift on $5M is $150-250K/year in incremental revenue against $6K/year in software. Below $2M GMV, $499/mo is hard to justify against free Shopify native upsells and a cheaper alternative like ReConvert at $30-100/mo.

**Loop Returns** charges $310/mo for the Advanced tier plus $1 per processed return (https://www.loopreturns.com/pricing). Its AI value is the exchange-first flow: when a customer wants to return, Loop's AI recommends an alternate SKU in their size or a complementary item, converting the return into an exchange roughly 30-45% of the time per Loop's published case studies. For a brand processing 500 returns/mo, that is $310 + $500 = $810/mo in software against potentially $30-50K/mo in retained revenue. **Okendo** ($135-$899/mo, https://www.okendo.com/pricing) and **Stamped** ($59-$179/mo public tiers, https://stamped.io/pricing) handle reviews; Okendo wins on AI moderation and UGC, Stamped wins on price. **Octane AI** ($50-$500/mo, https://www.octaneai.com/pricing) is the conversational quiz tool that pays for itself only on high-consideration categories — beauty, supplements, pet.

The integration architecture matters because every one of these tools reads from and writes back to Shopify. **Shopify Magic** lives inside the admin and writes directly to product, blog, and email entities — no integration to configure. **Klaviyo** uses Shopify's native integration to pull customers, orders, products, and event streams (Viewed Product, Added to Cart, Started Checkout, Placed Order, Fulfilled Order) into Klaviyo's profile graph. This is the single most important integration in the stack because Klaviyo's predictive models depend on at least 90 days of clean order data. Get this wrong and predicted LTV is garbage for six months.

**Gorgias** integrates via Shopify's helpdesk app, pulling order, fulfillment, and customer history into the ticket view so agents (and the AI) can answer WISMO and refund questions without leaving the helpdesk (https://www.gorgias.com/pricing). The Automate add-on uses Shopify's order data plus your macros to resolve tickets autonomously. **Rebuy** sits on the storefront via theme extensions and on Plus stores via checkout extensions; it reads order history and product catalog from Shopify and writes recommendation widgets back into PDP, cart, and checkout (https://rebuyengine.com/pricing). The data flow is mostly read-heavy — Rebuy does not write back to customer records.

**Loop Returns** integrates as a portal on a subdomain and writes back to Shopify as a draft order or exchange order, depending on configuration (https://www.loopreturns.com/pricing). Critically, Loop needs accurate inventory data to recommend exchange SKUs that are actually in stock, so brands with bad inventory hygiene will see the AI exchange flow break down fast. **Okendo** and **Stamped** read order history to send review request emails and write reviews back as product metafields for SEO and PDP display. **Octane AI** integrates via the storefront and writes quiz responses back to Shopify customer tags and to Klaviyo as profile properties, which is the key handoff — quiz data only earns its keep if it routes into segmented Klaviyo flows.

The order of operations for a new stack matters. Install Shopify and turn on Magic first (free, zero risk). Wire up Klaviyo second and let it backfill 90+ days of order data before you trust any predictive segment. Install Gorgias third and spend a week building macros and order tags before turning on Automate. Add Loop Returns and Okendo in parallel because they touch separate parts of the customer lifecycle and do not conflict. Layer Rebuy and Octane AI last, because both depend on a clean catalog and clean customer data to perform — and both are the most expensive to leave misconfigured.

Identity stitching is the silent killer. Shopify's customer ID is the source of truth, but Klaviyo uses email as primary key, Gorgias uses ticket-author email plus order ID, and Octane AI uses cookies until a quiz captures email. If a customer checks out as guest, then later logs in, you can end up with two Klaviyo profiles and a Gorgias ticket attached to neither. Brands that get this right run a quarterly identity audit in BigQuery or Hightouch reverse-ETL, merging profiles by email and Shopify customer ID — the ones that do not run that audit are sending duplicate flows and confusing their CSAT scores.

Let us actually do the math. A merchant at **≤$1M GMV** is on **Shopify Basic ($39/mo) or Shopify ($105/mo)** (https://www.shopify.com/pricing), running **Shopify Magic** (free), **Klaviyo** at the 1K-5K profile tier for $45-$150/mo (https://www.klaviyo.com/pricing), **Gorgias** Basic at $60/mo with no Automate yet (https://www.gorgias.com/pricing), **Stamped** Business at $59/mo for reviews (https://stamped.io/pricing), and probably no Rebuy, no Loop, no Octane. Total monthly cost: roughly $310-$510 software, or about $700-$1,500/mo when you add Shopify subscription, payment processing tools, and a transactional email service. The right call at this tier is to spend the AI budget on Klaviyo and skip Rebuy entirely.

At **$1-5M GMV**, you are on **Shopify ($105/mo) or Advanced ($399/mo)** running a real stack. **Klaviyo** jumps to the 10K-50K profile tier at $150-$700/mo as you grow your list, **Gorgias** moves to Pro at $360/mo with the Automate add-on at +30% (so $360 + $108 = $468/mo total) because ticket volume passes the threshold where humans cannot keep up (https://www.gorgias.com/pricing). **Okendo** Growth at $299/mo (https://www.okendo.com/pricing) replaces Stamped because the AI moderation and UGC matter at this scale, **Loop Returns** Advanced at $310/mo plus per-return fees starts paying back, and **Octane AI** Pro at $200/mo earns its keep if you sell beauty, supplements, or pet. Total: roughly $2,000-$5,000/mo software all-in.

At **$5-25M GMV**, you are almost certainly on **Shopify Plus at $2,300/mo** (https://www.shopify.com/pricing) and the stack gets serious. **Klaviyo** at 100K-250K profiles runs $900-$1,700/mo, **Gorgias** Advanced at $900/mo plus a 30% Automate add-on ($270/mo) totals $1,170/mo, **Rebuy** Pro flat $499/mo finally clears the ROI bar because a 3-5% AOV lift on $10M+ GMV is $300K-500K/year (https://rebuyengine.com/pricing), **Loop Returns** Advanced at $310/mo plus per-return fees scales to $1,500-3,000/mo at this volume, **Okendo** Power at $499/mo or Advanced at $899/mo (https://www.okendo.com/pricing), and **Octane AI** Pro at $200-500/mo. Total software: $6,000-$15,000/mo, plus Shopify Plus.

At **$25M+ GMV**, public pricing stops mattering because you are negotiating enterprise contracts. **Klaviyo** at 500K+ profiles is custom-quoted, typically $2,500-$5,000+/mo. **Gorgias** Enterprise with Automate is $1,500-$4,000+/mo depending on ticket volume. **Rebuy** Enterprise on Shopify Plus is typically $750-$2,000/mo. **Loop Returns** at this scale processes 5,000-20,000 returns/mo, putting software cost at $3,000-$10,000/mo. **Okendo** Enterprise runs $1,000-$2,500/mo. Add Shopify Plus at $2,300/mo base (and likely revenue-share above $800K/mo GMV, which kicks in around $9.6M annual), plus dedicated AI vendors for fraud, attribution, and warehouse optimization, and your total monthly software stack runs $15,000-$40,000/mo all-in.

The headline ratio matters more than the absolute number. A well-built stack at $1-5M GMV costs about 0.05-0.12% of GMV. At $5-25M, it should drop to 0.04-0.07%. At $25M+, ruthless procurement gets you to 0.02-0.05%. If your software bill is materially higher than this as a percentage of GMV, you are either over-buying or your stack is duplicating capabilities — the most common pattern we see is paying Klaviyo for AI subject lines and then paying a separate AI copy tool for the same job, or running both Stamped and Okendo because nobody cancelled the old contract.

**Klaviyo AI** pays back at every GMV tier above 500 profiles. The AI subject-line tester alone typically lifts open rates 8-15%, and the predictive LTV segments let you exclude low-value lookalikes from paid social audiences. There is no realistic scenario where a DTC brand serious about email skips Klaviyo, and the standalone alternatives (Drip, Omnisend, Brevo) either lack the predictive features or have worse Shopify integration. Pricing is transparent on the slider at https://www.klaviyo.com/pricing — the only gotcha is that suppressed and unsubscribed profiles do not count toward your active profile billing, so suppression hygiene is a meaningful cost lever.

**Gorgias Automate** pays back at $200+/mo in ticket volume, which roughly maps to 500+ tickets/mo. Below that, the +30% add-on cost is bigger than the labor it saves. The published Gorgias case studies claim 30-50% deflection rates, which is roughly accurate if your order tags, fulfillment events, and return reasons are clean — and roughly 15-20% if they are not. The real question is not whether to buy Automate, but whether to spend the four weeks of ops work to get your data clean enough for Automate to work, because that work is what unlocks the ROI, not the AI itself.

**Rebuy** is the most over-bought tool in this stack. At $499/mo flat, it pays back at $5M+ GMV where a 3-5% AOV lift covers the cost ten times over. Below $2M GMV, the math does not work — you are better off with native Shopify cross-sells and a $30-100/mo ReConvert subscription for post-purchase upsells. The middle ground ($2-5M GMV) is genuinely a coin flip and depends on your AOV — if your AOV is $40 and a Rebuy bundle bumps it to $48, you need significant volume to recover $499/mo. Run the math at https://rebuyengine.com/pricing before signing.

**Loop Returns** is a no-brainer above a 5% return rate and 300+ returns/mo. The exchange-first flow consistently retains 30-45% of return revenue that would otherwise be refunded, which at $50K/mo in return volume is $15-22K/mo in retained revenue against $310 + variable fees in software cost (https://www.loopreturns.com/pricing). Brands with sub-3% return rates (most food, beauty consumables) do not need Loop — Shopify's native returns plus a free portal is fine. Brands with 8%+ return rates (apparel, shoes) should treat Loop as required infrastructure, not optional software.

**Octane AI** is the conditional one. It pays back beautifully for high-consideration, recommendation-dependent categories — skincare quizzes that route to Klaviyo flows, supplement personalization quizzes, pet food sizing quizzes. It does not pay back for low-consideration categories where customers know what they want. If your category requires education before purchase, Octane AI at $200-500/mo (https://www.octaneai.com/pricing) is a strong yes. If your customers are repeat buyers who already know the SKU, skip it — a static quiz from Typeform plus a Klaviyo flow does 80% of the job for $50/mo.

**Shopify** prices on the pricing page (https://www.shopify.com/pricing) show the monthly subscription but bury two material costs. First, transaction fees of 2.0%/1.0%/0.6% on Basic/Shopify/Advanced apply to every sale not processed through Shopify Payments, which on $1M GMV using Stripe is an extra $6K-20K/year. Second, Shopify Plus at $2,300/mo flips to revenue share at roughly 0.25% of GMV once you cross $800K/mo, capped at $40K/mo. A $20M GMV Plus merchant is paying $50K/year in Shopify subscription, not $27.6K. Build the calculator with this in mind.

**Klaviyo** pricing (https://www.klaviyo.com/pricing) is the cleanest in the stack — the slider gives you a real number based on profile count, and the AI features are bundled. The trap is the email-plus-SMS combined plans, which look cheaper per channel but lock you into a higher tier than you need if your SMS list is small. A 50K-profile brand with a 5K SMS list is better off on the Email plan ($700/mo) plus the standalone SMS plan ($60/mo) than the combined plan at $760/mo — same price, more flexibility to scale channels independently.

**Gorgias** pricing (https://www.gorgias.com/pricing) hides two things. The Automate add-on at +30% of the base plan is documented but easy to miss; budget for it from day one if you are above 500 tickets/mo. The other one is the per-overage ticket charge above your plan's included volume, which on Pro is $36 per 100 extra tickets — a busy month can add $400+ in overages on top of the $360/mo plan. Either upgrade tiers or use the off-peak macros to deflect more before they become tickets.

**Rebuy** is honest about the flat $499/mo Pro tier (https://rebuyengine.com/pricing) but vague about the Shopify Plus tier, which is custom-quoted typically $750-$1,500/mo with annual commitment. **Loop Returns** at $310/mo Advanced (https://www.loopreturns.com/pricing) plus $1/return is also honest, but the higher Pro and Enterprise tiers add features (workflow automation, advanced policy logic, dedicated CSM) that many brands do not need — Advanced handles most use cases. Resist the upsell unless you have a specific feature gap.

**Okendo** (https://www.okendo.com/pricing) and **Stamped** (https://stamped.io/pricing) both publish public tiers but Okendo's Enterprise tier is custom-quoted, typically $1,500-2,500/mo with annual commitment. Stamped's Enterprise tier is similar. **Octane AI** (https://www.octaneai.com/pricing) publishes tiers up to $500/mo Enterprise, which is unusually transparent for the category. Across the whole stack, the rule is: assume the public mid-tier price is what you will pay at the mid-tier, and assume Enterprise is 2-3x the top public tier. Use that for budgeting — as of June 2026, verify at vendor.com/pricing before procurement.

Every tool in this stack handles PII — customer emails, addresses, order history, support conversations. **Shopify** is SOC 2 Type 2, PCI DSS Level 1, and offers EU data residency on enterprise plans (https://www.shopify.com/enterprise). **Klaviyo** is SOC 2 Type 2 and HIPAA-eligible on enterprise plans, with EU data residency available (https://www.klaviyo.com/legal). **Gorgias** is SOC 2 Type 2 and offers EU data residency on Advanced and Enterprise tiers (https://www.gorgias.com/security). For a US brand selling primarily in the US, default US residency is fine. For an EU brand or a brand with material EU revenue, EU residency is non-negotiable under GDPR.

AI-specific evaluation matters more than vendors admit. **Gorgias Automate** can hallucinate order status if your fulfillment events are stale — the AI confidently tells a customer their order shipped yesterday when it actually did not. The fix is to set tight confidence thresholds and route to human on any low-confidence response, which costs you deflection rate but protects CSAT. **Rebuy**'s AI recommendations occasionally surface out-of-stock items if inventory sync lags; check the recommendation engine settings to require positive inventory before display. **Octane AI** quiz logic can ship wrong recommendations if the quiz tree has dead ends — audit the tree quarterly.

SSO and SAML matter once you have more than ten staff users. **Gorgias** SAML is available on Advanced ($900/mo) and Enterprise (https://www.gorgias.com/pricing). **Klaviyo** SSO is enterprise-only. **Shopify Plus** offers org-level SSO and granular permissions through Shopify Organization Admin. **Okendo** SSO is on Power and above. If you are scaling past a 20-person team without SSO, you are accumulating offboarding debt — every departed contractor whose Klaviyo seat you forgot to revoke is a data exfiltration risk.

PII minimization is the under-discussed lever. None of these tools need the customer's full credit card or government ID. They do need email, name, shipping address, order ID, and SKU history. Audit your Klaviyo profile properties quarterly and delete unused custom fields — every property is data you are storing and paying to keep. **Loop Returns** stores return reasons and product comments that often contain PII; configure retention to delete after 24 months. **Gorgias** stores entire conversation history; configure auto-deletion of tickets older than 36 months unless legal requires longer.

Self-hosting is not a realistic option for any tool in this stack. **Shopify Magic** is bundled with Shopify and cannot be self-hosted. **Klaviyo**, **Gorgias**, **Rebuy**, **Loop**, **Okendo**, and **Octane AI** are all SaaS-only with no on-prem offering. If you absolutely need on-prem AI for compliance, you are looking at a different architecture entirely — a custom-built stack on AWS or GCP using foundation models directly, with all the integration burden that implies. For 99% of Shopify merchants, SaaS with strong DPAs and EU residency is the correct trade-off; the operational cost of self-hosting equivalent functionality would dwarf the SaaS bills above $25M GMV.

The first and most common mistake is paying for AI copy twice. Brands install Jasper or Copy.ai at $50-100/mo on top of Shopify, not realizing **Shopify Magic** does product descriptions and email subject lines for free as part of the bundled $39-$2,300/mo subscription (https://www.shopify.com/magic). Unless you have a 10K+ SKU catalog requiring structured attribute generation or a brand voice that needs heavy fine-tuning, Magic plus a free internal style guide replaces the standalone tool. We have seen brands save $1,200/year by cancelling Jasper after they realized Magic was already installed.

The second mistake is running both **Stamped** and **Okendo** in parallel because nobody cancelled the older contract. We see this constantly in audits — a brand migrated from Stamped to Okendo two years ago, still pays Stamped $179/mo, and uses neither for net-new review collection. That is $2,148/year of pure waste. Audit your Shopify app subscriptions in admin → settings → billing every quarter; cancel anything not actively used by name. Same applies to Yotpo and Judge.me leftovers from earlier in your stack history.

The third mistake is over-buying **Rebuy** below $2M GMV. The $499/mo Pro tier (https://rebuyengine.com/pricing) does not pencil out below ~$2M GMV unless your AOV is high enough that a 3-5% lift returns more than the software cost. Brands at $800K GMV install Rebuy on a 21-day trial, the trial converts, and they discover six months later that the $6K/year in software cost actually exceeded the incremental AOV. Run the post-implementation math at day 60 and cancel if the lift is below 3%.

The fourth mistake is paying for **Gorgias Automate** without doing the macro and tag hygiene work first. Automate is +30% of your base plan (https://www.gorgias.com/pricing) — on Pro that is $108/mo. If your macros are stale and your order tags are inconsistent, Automate's deflection rate will sit at 10-15% instead of the 30-50% Gorgias advertises. You are paying $108/mo for the privilege of having an AI that does not work. Spend two weeks cleaning up macros and tags before turning Automate on; this is the single highest-ROI ops project in the entire stack.

The fifth mistake is running **Octane AI** on a low-consideration category. A grocery snack brand does not need a quiz — their customers know they want the cookies. A skincare brand absolutely needs a quiz because the customer does not know which serum to buy. Octane AI at $200-500/mo (https://www.octaneai.com/pricing) pays back beautifully on the second case and is pure cost on the first. Audit quiz completion rate at day 30 — below 25% completion means your customers do not need the quiz, and you should kill it.

Shopify is aggressively expanding **Shopify Magic** and Sidekick — the 2025 roadmap added multi-product variant generation, AI-assisted theme editing, and bulk catalog operations. By late 2026, expect Magic to encroach further on standalone AI copy tools and on the lower tiers of **Octane AI**'s quiz capabilities, because Shopify keeps adding native conversational features into the storefront. If you are evaluating a new standalone AI tool today, ask the vendor specifically what their moat is once Shopify ships the equivalent free — if the answer is hand-wavy, do not sign a multi-year contract.

**Klaviyo** continues to push AI subject-line generation and predictive segments deeper into the standard plans, which is the right direction (https://www.klaviyo.com/pricing). The competitive threat is from Klaviyo's expanding CDP and reviews ambitions — Klaviyo Reviews launched in late 2024 and is genuinely competitive with Stamped at $59/mo. If you are at the ≤$1M GMV tier and you are already on Klaviyo, evaluate Klaviyo Reviews before signing a separate Stamped contract; consolidating to one vendor saves $700+/year and one less integration to maintain.

**Gorgias** is pushing Automate harder and pricing it more aggressively into the base plans through 2026, but the +30% add-on structure remains (https://www.gorgias.com/pricing). Watch for a possible plan restructure where Automate becomes table stakes in the Advanced tier rather than an add-on — if that happens, expect base prices to rise to absorb the cost. The competitive threat is Shopify Inbox plus Shopify's own AI helpdesk experiments, which are real but currently nowhere near Gorgias-level for high-volume brands.

**Rebuy** and **Loop Returns** are both in the position of needing to justify flat fees against an ecosystem that is shipping more native equivalents. Rebuy's response has been deeper Plus-only checkout features and tighter Klaviyo integration. Loop's response has been better exchange-flow AI and a Returns Manager dashboard that genuinely outperforms anything native. Both are still worth paying for at the right GMV tier, but both vendors will see fee pressure if the native alternatives get materially better in 2026.

The macro picture: Shopify is on a clear path to bundling more AI capabilities into the base subscription, which is good for merchants and bad for standalone AI app vendors. The smart move for a merchant in 2026 is to keep contracts short, avoid multi-year annual commitments unless the discount is material (20%+), and re-audit the stack every six months. The bill you wrote yesterday should not be the bill you write next quarter — as of June 2026, the AI Shopify app market is moving fast enough that locked-in pricing is a liability, not an asset.
