Last updated: April 2026 · Pricing and ratings verified from live Shopify App Store listings on April 30, 2026. Reviewed by the Libautech team — builders of Built for Shopify apps used by 5,000+ merchants across 50+ countries.
Most roundups of Shopify COD apps list 8 tools as if they competed directly. They do not. An OTP verification app, a payment rules app, and a 1-click COD order form solve three different problems for stores in COD-heavy markets. Lumping them together makes it impossible to decide what to install.
The honest framing: Shopify COD apps break into three jobs, each solving a different bottleneck for stores selling into India, Egypt, the Gulf, North Africa, Southeast Asia, and parts of Latin America where Cash on Delivery is the dominant payment method.
The first job is OTP and RTO verification — confirming the customer's phone number and intent to purchase before the order ships. Apps like Hillteck, COD King, and CODBot send an OTP via SMS or WhatsApp at checkout, validate the customer answered, and flag high-RTO-risk orders before shipping label generation. This is where 50–80% of fake orders get filtered out.
The second job is COD fees and payment rules — charging an extra fee on COD orders to cover RTO risk, hiding COD on low-margin products or international addresses, and offering a prepaid discount to convert COD shoppers to prepaid. Apps like Releasit COD Fee, ACOD, and Payflow handle this layer through conditional rules at the Shopify checkout.
The third job is COD order forms for dropshipping — replacing the standard Shopify checkout with a 1-click form built for COD-first markets where checkout abandonment is high because customers expect a simpler buying flow. Releasit COD Form, EasySell COD Form, and CodForm are landing-page-style COD checkouts with built-in upsells, OTP, and Facebook/TikTok pixel tracking. This is the layer most COD dropshippers in the Middle East, North Africa, and Southeast Asia actually run.
This post ranks 8 apps across the three jobs based on verified April 2026 Shopify App Store data and what each one actually solves.
COD apps stack with broader checkout and shipping tools. See our guides on best Shopify cart customization apps for the broader checkout rules layer, best Shopify shipping apps for the carrier-side workflow, and best Shopify order tracking apps for the post-purchase confirmation layer.
| App | Rating | Free Plan | Paid From | Layer | Best For |
|---|---|---|---|---|---|
| COD King — OTP & Partial COD | ⭐ 5.0 (1,000+) | Yes (free to install) | Pay per OTP | OTP verification | OTP plus partial payment for fake-order filtering |
| Releasit COD Form & Upsells | ⭐ 4.8 (2,627+) | Yes (free to install) | $29.99/mo | COD order form | Dropshipping with 1-click COD landing pages |
| Hillteck — COD OTP Verification | ⭐ 4.9 (1,500+) | No (pay per use) | ~$0.025/call | OTP verification | High-volume India COD with IVR fallback |
| Releasit COD Fee & Partial Pay | ⭐ 5.0 (4,500+) | Yes | $9.99/mo | COD fees + rules | Conditional COD fees with WhatsApp OTP |
| EasySell COD Form & Upsells | ⭐ 4.9 (758+) | Yes (free to install) | $9.95/mo | COD order form | Budget COD form alternative to Releasit |
| ACOD — COD Fee | ⭐ 4.8 (200+) | Yes | $5.95/mo | COD fees + rules | Lowest-cost COD fee app, country-based rules |
| Payflow — COD & Payment Rules | ⭐ 4.9 (300+) | Yes | $9.99/mo | COD fees + rules | Native Shopify Functions, AND/OR rule logic |
| CODBot — SMS Verification | ⭐ 4.6 (300+) | No (pay per OTP) | Pay per OTP/IVR | OTP verification | SMS plus IVR fallback for OTP delivery failures |
This is the highest-ROI layer for any COD-heavy store. Without OTP verification, every fake or impulse-canceled order ships out, gets refused at the door, and returns to origin — costing the merchant the round-trip shipping fee plus restocking time. With OTP verification, the customer enters a code sent to their phone before the order is confirmed; if no OTP arrives, the order doesn't ship. Three apps lead this layer.
Best for: COD-heavy Shopify stores wanting OTP verification combined with the partial-payment mechanic where customers commit a deposit upfront to filter out non-serious buyers — the strongest fake-order filter available in 2026.
COD King holds 5.0 stars across 1,000+ reviews on the Shopify App Store and carries the Built for Shopify badge. The differentiator is the partial COD workflow — customers commit a deposit (fixed or percentage) on the COD order at checkout, then pay the remaining balance when the package arrives. This single mechanic produces documented 50%+ reductions in fake orders because joke buyers and joy-reservers will not commit even a small deposit upfront. Standard OTP verification (sending an SMS code) catches obvious fakes; partial payment catches the entire "will-not-pay-on-delivery" segment.
Beyond partial COD, the app handles standard OTP verification via SMS or WhatsApp, conditional COD show/hide based on location, cart value, or product type, branded SMS for order confirmation and fulfillment updates, and a Convert COD to Prepaid feature that offers a discount to encourage customers to switch from COD to prepaid checkout (currently supported in India and Egypt). The pricing model is pay-per-OTP, so cost scales linearly with COD volume rather than fixed monthly subscription.
Where it falls short: pay-per-OTP pricing makes monthly cost variable and harder to budget than a flat subscription. The Convert COD to Prepaid feature is region-locked to India and Egypt, so stores in MENA and Southeast Asia cannot access it. Some merchant complaints note slow support response on edge-case configuration issues during peak periods.
Pricing: Free to install. Pay-per-OTP charged based on SMS or WhatsApp volume. Partial COD and feature access included on free install.
Best for: high-volume India and South Asia COD stores wanting OTP verification with IVR voice-call fallback when SMS delivery fails — the most resilient verification stack for unreliable SMS delivery markets.
Hillteck holds 4.9 stars across 1,500+ reviews. The positioning is OTP-first verification with redundancy — if the customer doesn't respond to SMS or WhatsApp OTP within a window, the system falls back to an automated IVR voice call to confirm the order. For stores in markets where SMS delivery is unreliable due to telecom blocking or carrier filtering, IVR fallback recovers verification on orders that would otherwise time out and ship as unverified.
Pricing is pay-per-call (around $0.025 per IVR call) and pay-per-SMS or pay-per-OTP, with no fixed monthly subscription. The app integrates with WhatsApp for both verification and post-purchase notifications (order confirmation, shipping updates, out-for-delivery, delivered alerts), and the COD-to-prepaid conversion flow uses UPI for one-click prepaid switching, which is highly relevant for Indian merchants. Several merchant reviews specifically credit Hillteck with reducing manual call workload by 60–70%.
Where it falls short: pricing-per-event is harder to forecast than flat-fee apps and can compound at very high COD volumes. The IVR voice quality varies by carrier and language, with some merchants reporting accent recognition issues on certain regional Indian languages. The interface is functional rather than design-forward compared to Releasit or COD King.
Pricing: Free to install. Pay-per-event: ~$0.025 per IVR call, ~$0.0064 per SMS, ~$0.015 per OTP.
Best for: COD-heavy Shopify stores wanting straightforward SMS-based OTP verification with optional IVR fallback at the lowest per-event pricing in this layer.
CODBot holds 4.6 stars across 300+ reviews. The positioning is functional OTP verification without the partial-payment mechanic of COD King or the multi-channel notification stack of Hillteck. The core feature set is SMS or WhatsApp OTP at checkout, IVR fallback if OTP delivery fails, and a per-COD-fee charge configuration. Some merchant reviews report 60–70% reductions in manual confirmation calls and meaningful drops in fake orders after install.
Where it falls short: review base (300+) is significantly smaller than COD King or Hillteck. Several recent reviews flag intermittent app-stops-working issues with slow support response, including one merchant reporting lost top-up wallet credit after a malfunction. For stores that depend on COD verification as critical infrastructure, the support reliability gap versus higher-rated alternatives is the watch-out.
Pricing: Free to install. Pay-per-OTP and pay-per-IVR billing.
This layer handles the post-verification economics. Once OTP is filtering fake orders, the next bottleneck is COD-driven margin erosion: paying the round-trip RTO cost on the orders that do ship and get refused, and absorbing the higher fulfillment cost of cash collection on every COD order. Three apps cover the conditional-rules layer that mitigates this through COD fees, prepaid discounts, and conditional-show logic.
Best for: most COD-heavy Shopify stores wanting conditional COD fees plus WhatsApp OTP verification plus partial COD payments in one Built for Shopify app — the highest-rated, most-reviewed app in this layer.
Releasit COD Fee & Partial Pay holds 5.0 stars across 4,500+ reviews and carries the Built for Shopify badge. The differentiator is feature breadth — conditional rules by country, product, collection, customer group, or order value to apply fees or discounts; WhatsApp OTP verification at checkout to block fake orders; and partial, split, or deposit COD payments upfront with full payment tracking by date, method, and amount. The app supports 19 languages including Spanish, French, Italian, German, Polish, Thai, Turkish, and Brazilian Portuguese, which makes it the strongest fit for stores selling internationally.
Pricing is the standout: $9.99/month for the entry tier, which is significantly less than the per-OTP costs of OTP-only apps once volume passes 400 orders per month. The app sits inside Shopify's standard checkout (rather than replacing it), so it integrates cleanly with other Shopify Functions apps and does not break checkout-related analytics. For merchants whose biggest COD problem is fee economics rather than fake-order volume, Releasit COD Fee is the right entry point.
Where it falls short: this is a fees-and-rules app, not a 1-click COD form replacement — if your store needs to bypass standard Shopify checkout because COD market customers expect a simpler form, you need Releasit's separate COD Form & Upsells app instead (covered in Layer 3). The OTP feature is included but lighter than dedicated OTP apps like COD King or Hillteck on partial-payment workflows or IVR fallback.
Pricing: Free plan available. Paid from $9.99/month. 14-day free trial on paid tiers.
Best for: budget-conscious Shopify stores wanting basic COD fee and conditional show/hide rules at the lowest entry pricing in this layer.
ACOD holds 4.8 stars across 200+ reviews. The positioning is narrow on purpose — add a fixed or percentage COD fee, link COD to specific shipping methods, and hide or show COD based on shipping country, product type, or order conditions. Pricing starts at $5.95/month, which is the lowest in this layer.
Where it falls short: feature breadth is genuinely lighter than Releasit COD Fee or Payflow. There is no OTP verification, no partial-payment workflow, no multilingual checkout text, and no advanced AND/OR rule logic for combining multiple conditions. ACOD makes sense primarily when the only job is "add a flat fee on COD orders" and the store does not need verification or complex conditional rules. For most stores at $1K+/month in COD volume, the feature gap to Releasit COD Fee is worth the $4 difference.
Pricing: Free plan available. Paid from $5.95/month.
Best for: Shopify stores wanting native Shopify Functions performance with sophisticated AND/OR rule logic for combining multiple conditions on payment and delivery method visibility.
Payflow holds 4.9 stars across 300+ reviews. The differentiator is technical — the app is built on native Shopify Functions (the current supported API after Shopify Scripts deprecation in June 2026), which means rule evaluation runs at checkout latency and survives Shopify's API migration without breaking. The advanced condition tool combines AND/OR logic so merchants can build rules like "hide COD when order total is over $200 AND customer ships to international address AND product is from collection X."
Pricing is $9.99/month for the entry tier with a free plan available, which is comparable to Releasit COD Fee. The app handles hide/rename/reorder for both payment methods and delivery methods, which extends beyond pure COD use cases into broader checkout customization.
Where it falls short: review count (300+) is much smaller than Releasit COD Fee (4,500+) or COD King (1,000+). The app does not include OTP verification or partial COD payments, so stores wanting an integrated fees-plus-verification stack will need to add a dedicated OTP app on top. Payflow's strength is rule logic, not feature breadth.
Pricing: Free plan available. Paid from $9.99/month.
This is the layer most COD-heavy dropshippers in MENA, North Africa, and Southeast Asia actually run. Standard Shopify checkout is built for prepaid, address-rich, multi-step buying flows. In COD-dominant markets, customers expect a simpler form — name, phone, address, one click — and standard checkout abandonment rates can hit 70%+. COD order form apps replace standard checkout with a 1-click landing page form that cuts abandonment dramatically. Two apps lead this layer.
Best for: dropshipping Shopify stores in COD-heavy markets (MENA, North Africa, Southeast Asia, parts of Eastern Europe) wanting a 1-click COD form replacing standard checkout with built-in upsells, OTP verification, and Facebook/TikTok pixel tracking.
Releasit COD Form & Upsells holds 4.8 stars across 2,627+ reviews and carries the Built for Shopify badge. The positioning is an alternative checkout flow specifically for COD-first markets. Customers click an Add to Cart button, see a popup or full-page form (name, phone, address, quantity), and complete the order in 1 click — bypassing standard Shopify checkout entirely. The form supports custom fields, custom layouts, Google address autocomplete, OTP phone verification, and IP/postal-code blocking for fraud prevention.
Beyond the form itself, the app includes upsells, downsells, in-form quantity offers, A/B testing on 1-click upsells, multi-currency support via Shopify Markets, and event tracking integrations with Facebook, TikTok, Google, Pinterest, and Snapchat. The combination of a simpler checkout flow plus integrated upsells delivers a measurable conversion rate lift versus standard Shopify checkout for COD-heavy traffic. Multiple merchant reviews specifically credit Releasit with "dramatic conversion rate increase" versus the default checkout.
Where it falls short: a few documented stability incidents in 2025–2026 (one merchant reported the app failed during a Black Friday period costing significant ad spend; another reported a 10-day support response delay during a separate outage). These are real events that merchants should weigh against the conversion benefits. The app also does not work with abandoned cart recovery flows or Shopify's standard live customer behavior tracking because it bypasses the standard checkout. Cost can climb as the store scales because pricing models include per-order or per-form fees on higher tiers.
Pricing: Free to install. Paid from $29.99/month. Free trial available.
Best for: dropshipping Shopify stores wanting a budget alternative to Releasit — same 1-click COD form architecture with upsells and OTP at lower entry pricing.
EasySell COD Form & Upsells holds 4.9 stars across 758+ reviews. The positioning is functionally similar to Releasit COD Form — 1-click order form replacing standard checkout, customizable fields and layout, upsell offers, OTP verification, and pixel tracking for Facebook and TikTok. The differentiator is pricing: $9.95/month for the entry tier versus $29.99/month for Releasit, which makes EasySell a meaningful cost saving for stores at lower COD volumes.
The app integrates with Google Sheets for order export, supports multi-language checkout text, and includes basic analytics on form conversion rate. For dropshippers running multiple test stores, the lower per-store pricing of EasySell stacks better economically than running Releasit on every store.
Where it falls short: review count (758+) is roughly 3x smaller than Releasit (2,627+), so social proof at install decision is weaker. Feature depth at the entry tier is genuinely lighter than Releasit on advanced upsell mechanics (A/B testing, in-form quantity offers, multi-currency via Shopify Markets). For high-volume single-store operators, Releasit's larger feature set generally justifies the price gap; for early-stage testers running multiple stores, EasySell wins on economics.
Pricing: Free to install. Paid from $9.95/month.
For OTP verification with the strongest fake-order filtering: COD King. Partial COD mechanic plus OTP, 5.0 stars, pay-per-event pricing.
For high-volume India COD with IVR voice fallback when SMS fails: Hillteck. 4.9 stars, IVR redundancy, UPI integration for COD-to-prepaid conversion.
For straightforward SMS OTP verification with IVR fallback at lowest per-event cost: CODBot. 4.6 stars, smaller install base, watch the support reliability gap.
For most COD-heavy stores wanting conditional COD fees plus WhatsApp OTP plus partial payments in one app: Releasit COD Fee & Partial Pay. 5.0 across 4,500+ reviews, $9.99/month, 19-language support, the strongest pick in this layer.
For budget-conscious stores wanting basic COD fees only: ACOD. $5.95/month, 4.8 stars, no OTP or partial payments.
For native Shopify Functions performance with advanced AND/OR rule logic: Payflow. 4.9 stars, $9.99/month, future-proof against Shopify Scripts deprecation.
For dropshipping stores in MENA, North Africa, or Southeast Asia wanting 1-click COD landing pages: Releasit COD Form & Upsells. 4.8 across 2,627+ reviews, $29.99/month, conversion rate lift versus standard checkout, watch the past stability incidents.
For budget COD form alternative with same architecture at lower pricing: EasySell COD Form & Upsells. 4.9 across 758+ reviews, $9.95/month entry tier, lighter feature depth.
For most COD-heavy Shopify stores under $50K/month, the honest stack recommendation is two apps. Install Releasit COD Fee & Partial Pay (Layer 2) for conditional COD fees and WhatsApp OTP at $9.99/month, then add COD King (Layer 1) for the partial-payment fake-order filter at pay-per-OTP cost. Combined cost is typically $15–40/month at small scale. Skip Layer 3 (COD order forms) unless you are running paid traffic dropshipping into MENA or Southeast Asia where the standard Shopify checkout flow itself is the conversion bottleneck — in those markets, Releasit COD Form replaces the checkout entirely and is worth the $29.99/month cost.
This ranking is based on four criteria applied to every Shopify COD app tested in 2026. First, Shopify App Store rating and verified review volume as of April 30, 2026 — the strongest signal of long-term merchant satisfaction at scale. Second, fit-to-job for which of the three layers each app actually solves (OTP verification, fees and rules, or COD order form), rather than generic feature checklists. Third, pricing structure and total cost of ownership at realistic merchant COD volumes — pay-per-event apps scale differently than flat-monthly apps, and the cost crossover point depends on order volume. Fourth, depth of region-specific features that matter in COD-heavy markets — IVR fallback for unreliable SMS delivery, UPI for India COD-to-prepaid conversion, multilingual checkout for MENA and Southeast Asia, country-conditional rule logic.
Every pricing figure in this post was verified directly from each app's live Shopify App Store listing on April 30, 2026. COD app pricing structures change frequently — confirm current pricing on the official listing before installing. Ratings and review counts reflect the Shopify App Store at the time of our last update.
A Shopify COD (Cash on Delivery) app handles one or more of three jobs. OTP verification apps confirm the customer's phone number and intent to purchase before shipping the order, filtering out fake orders that would otherwise return to origin. COD fees apps add a conditional fee on COD orders to cover RTO risk and offer prepaid discounts to convert COD shoppers to prepaid. COD order form apps replace standard Shopify checkout with a 1-click landing page form built specifically for COD-first markets where standard checkout abandonment is high.
Depends on the layer. For OTP verification with partial-payment fake-order filtering: COD King (5.0 stars, pay-per-OTP pricing). For conditional COD fees plus WhatsApp OTP plus partial payments in one app: Releasit COD Fee & Partial Pay (5.0 across 4,500+ reviews, $9.99/month, the strongest pick in the fees-and-rules layer). For 1-click COD landing pages replacing standard checkout in dropshipping markets: Releasit COD Form & Upsells (4.8 across 2,627+ reviews, $29.99/month).
RTO (Return to Origin) is when a customer refuses delivery, the carrier returns the package to the merchant, and the merchant absorbs the round-trip shipping cost plus restocking time. RTO is the silent killer of COD profit margins because every fake order or impulse-canceled order ships out, gets refused, and returns at the merchant's expense. In COD-heavy markets, RTO rates of 20–40% are typical without verification, and 5–15% with proper OTP and partial-payment filtering. The right COD app pays for itself in saved shipping costs within the first week on stores doing 100+ COD orders monthly.
At checkout, after the customer enters their phone number, the app sends a one-time-password code via SMS or WhatsApp. The customer enters the code on the checkout page to confirm both the phone number is real and the customer is genuinely ordering. If no OTP is entered, the order is held or canceled and never ships. This single mechanic filters 50–80% of fake orders — joke buyers, accidental clicks, and address-stuffing fraud will not complete the OTP step.
Partial COD requires the customer to commit a fixed deposit or percentage of the order value upfront at checkout (paid via card, UPI, or prepaid wallet), with the remaining balance collected in cash on delivery. The mechanic filters out non-serious buyers who will not commit even a small deposit, while preserving the COD experience for genuine customers. Stores using partial COD typically see 50%+ reductions in fake orders versus full COD without any deposit. COD King is the leading app for partial COD workflows.
For most COD-heavy stores, yes — a small COD fee (typically $1–3 USD equivalent) covers part of the RTO risk per order and creates an economic incentive for customers to switch to prepaid. The fee should be small enough to not deter genuine COD buyers but high enough to make prepaid checkout look attractive when paired with a small prepaid discount. Releasit COD Fee, ACOD, and Payflow all support conditional COD fees that apply only on certain countries, products, or order values.
Only if you are running paid traffic dropshipping into COD-heavy markets where standard checkout abandonment is over 70%. In MENA, North Africa, parts of Southeast Asia, and parts of Eastern Europe, customers expect a 1-click form (name, phone, address) rather than the multi-step Shopify checkout. Releasit COD Form and EasySell COD Form replace standard checkout with this simpler flow and typically deliver meaningful conversion lifts on COD traffic. For prepaid-dominant markets (US, UK, EU, Japan), do not replace standard Shopify checkout — the trade-offs (loss of abandoned cart flows, Shopify analytics, Shop Pay) are not worth it.
OTP verification apps and COD fee apps that run inside standard Shopify checkout add minimal overhead because verification happens at the checkout step, not on every product page. Built for Shopify-certified apps including COD King, Releasit COD Fee & Partial Pay, and Payflow load efficiently. COD order form apps (Releasit COD Form, EasySell) replace standard checkout entirely and add their own JavaScript bundle, which has measurable load impact on the order form page itself but does not affect product page speed. Always test page speed before and after install with Google PageSpeed Insights.
Two mechanics work in combination. First, charge a small COD fee on COD orders so prepaid checkout looks economically attractive. Second, offer a prepaid discount (typically 3–7% off) when customers select prepaid at checkout. COD King and Hillteck both include a Convert COD to Prepaid feature that sends the customer a follow-up message with a one-click prepaid switch link (UPI in India, Stripe or PayPal elsewhere). For stores in India, the COD King Convert to Prepaid workflow plus a 5% prepaid discount commonly converts 15–30% of COD orders to prepaid before shipping.
Two different apps from the same company solving two different jobs. Releasit COD Fee & Partial Pay is a fees-and-rules app that adds COD fees, conditional rules, and OTP verification inside the standard Shopify checkout (Layer 2 in this guide). Releasit COD Form & Upsells is a 1-click order form that replaces standard Shopify checkout entirely, primarily used by dropshippers in COD-first markets (Layer 3 in this guide). Most stores need one or the other, not both — choose based on whether you want to keep standard checkout or replace it.
Yes. All apps in this list work on Shopify Plus and on standard Shopify plans. Apps using native Shopify Functions (Payflow, Releasit COD Fee, ACOD) are particularly compatible with Shopify Plus's customizable checkout. Note that Shopify Scripts (the legacy checkout customization API) is being deprecated in June 2026 — if you are currently using a Scripts-based COD customization tool, migrate before that date to avoid checkout breakage.
