Free Tools for a New Online Store: Plans and Limits (2026)

You can launch a new online store without paying monthly software subscriptions. Several major ecommerce tools offer genuine $0 plans for email marketing, shipping labels, payment processing, and on-demand fulfillment.

This guide breaks down what a realistic $0 starter stack looks like, the math behind everyday orders, and the exact limits where each free tool stops being enough. All subscription prices, transaction rates, and feature tiers are US rates checked on official pricing pages on 2026-10-03.

The free stack in one table

Worked example: what a month costs at 30 orders ($0 stack vs paid upgrades)

These stores are hypothetical examples with simple, realistic figures, but every software price and payment rate comes from official pricing checked on 2026-10-03. Both stores sell a made-up $40 item with $12 product cost and $6 customer postage.

Store A: a lean starter on the $0 software stack (30 orders a month, $1,200 revenue)

Store A pays $0 in software subscriptions. It uses MailerLite Free ($0) for email, Pirate Ship ($0 monthly fee) for shipping labels, USPS Priority Mail flat rate boxes ($0 for packaging supplies), and Square Free ($0 per location) to take payments online.

• Monthly subscriptions: $0.
• Online card processing fees on Square Free (3.3% + 30¢): 3.3% of $1,200 ($39.60) plus 30¢ × 30 ($9.00) = $48.60.
• Product inventory cost: 30 units × $12 = $360.00.
• Carrier postage paid through Pirate Ship: 30 labels × $6 = $180.00.

Store B: the same store with premature paid subscriptions

Store B has the exact same 30 orders ($1,200 revenue), but upgraded early to Square Plus ($49/month to lower card rates to 2.9% + 30¢) and MailerLite Comfort ($12/month for up to 1,000 subscribers).

• Monthly subscriptions: $49 (Square Plus) + $12 (MailerLite Comfort) = $61.00.
• Online card processing fees on Square Plus (2.9% + 30¢): 2.9% of $1,200 ($34.80) plus 30¢ × 30 ($9.00) = $43.80.
• Product inventory cost: 30 units × $12 = $360.00.
• Carrier postage: 30 labels × $6 = $180.00.
• Combined product and postage: $360.00 + $180.00 = $540.00.
• Total monthly cost: $61.00 (subscriptions) + $43.80 (card fees) + $540.00 (product and postage) = $644.80.
• Net profit: $1,200.00 revenue minus $644.80 costs = $555.20.
• Fee savings: $48.60 minus $43.80 = $4.80.
• Profit difference: $611.40 minus $555.20 = $56.20.

Upgrading saved $4.80 in card fees but added $61 in software. Store B ended the month with $56.20 less profit.

The break-even rule on paid upgrades

Square Plus lowers online card fees by 0.4 percentage points (from 3.3% to 2.9%). To cover the $49 monthly fee, you must process $12,250 per month in online card sales ($49 ÷ 0.004). Below $12,250 a month, Square Free leaves more cash in your bank account.

Run it with your own numbers: total monthly cost = subscription fees + (gross sales × card %) + (orders × per-transaction fee) + product costs + shipping postage. Check our profit per order calculator to test your own margin per item, or read the monthly cost guide for whole-store budgeting.

Free email marketing tools

Email lets you build an audience you own from day one. These three tools provide functional $0 tiers with clear ceilings. For a broader comparison, see our email marketing guide.

MailerLite: best for maximum monthly sends

MailerLite’s Free plan costs $0 per month and includes up to 250 active subscribers with 2,500 monthly emails. The plan includes campaigns, automations, 1 website, 1 landing page, signup forms, and 3 email editors with 2 user seats. Sending is locked if your list exceeds 250 subscribers. Once you cross 250, you must upgrade to Comfort, which starts at $12 per month for up to 1,000 subscribers. MailerLite also offers a 14-day free trial of premium features with 24/7 support.

Omnisend: best for built-in ecommerce support

Omnisend’s Free plan costs $0 per month with no credit card required. It supports up to 250 contacts and allows up to 500 emails and 500 web push notifications per month. It provides full access to core features including automations, signup forms, segmentation, SMS, and audience sync. Omnisend includes 24/7 live chat and email support on all plans, including Free. When your list grows past 250 contacts, the Standard plan starts at $16 per month for up to 500 contacts.

Klaviyo: best for data-driven flow automations

Klaviyo’s Free plan is $0 per month and includes up to 250 active profiles, 500 email sends per month, $5 of mobile messages per month (150 SMS/MMS credits), and $5 of AI Composer usage per month. You get full access to segmentation, email and SMS editors, web forms, built-in analytics, and flow automations. Email support is included for the first 60 days only; after that, support is limited to the Help Center, Academy, and Community. Detailed plan tiers are covered in our Klaviyo pricing guide and Klaviyo vs Omnisend comparison.

Free shipping tools: Pirate Ship

Printing postage at retail counter rates cuts deeply into margins. Pirate Ship solves this without a monthly subscription.

Its home page lists no monthly fees, markup or hidden costs and provides free shipping software for UPS and USPS labels. You connect your store, purchase postage at carrier rates, and print labels. UPS discounts are off Daily Rates and limited to shipments originating in the United States.

You can also order USPS Priority Mail and Priority Mail Flat Rate boxes and envelopes directly from the USPS postal store at $0. You still pay carrier postage whenever you ship a package, which our shipping basics guide and shipping label tool comparison break down.

Free payment processing: Square

Square lets you collect payments without a monthly gateway charge.

The Square Free plan costs $0 per month per location. You only pay processing fees when you take a payment. Payouts transfer to an external bank account the next business day for free, or instantly for a fee.

Processing fees apply to every transaction:

• Online card payments: 3.3% + 30¢ on Square Free (compared to 2.9% + 30¢ on Square Plus at $49/mo).
• In-person payments (tap, dip, or swipe): 2.6% + 15¢ on Square Free.
• Manual entry or card on file: 3.5% + 15¢ across all plans.
• Afterpay transactions: 6% + 30¢.

Free print on demand: Printful and Printify

Print on demand lets you sell apparel, accessories, and home goods without buying inventory up front. Both platforms offer $0 monthly plans where you only pay when an order arrives.

Printful

Printful’s Free plan costs $0 per month. You pay for product, fulfillment, shipping, and taxes only when an order is placed. This removes inventory risk while validating designs. Printful also offers a Growth plan at $24.99 per month, which is free when you reach $12,000 per year in sales ($1,000 per month). Read our print on demand guide for fulfillment details.

Printify

Printify’s Free plan is $0 per month and includes up to 5 stores per account, unlimited product designs, 24/7 merchant support, manual order creation, and integrations with Shopify, Etsy, and eBay. Printify’s Premium plan costs from $24.99 per month when billed annually and unlocks up to 20% discounts on products. Upgrading only makes sense once product discounts exceed the $24.99 monthly cost. Our Printify pricing guide and Printful vs Printify comparison map out the crossover.

Website platforms: what is and is not free

Finding a free platform to host your storefront and process transactions requires knowing where vendors draw the line.

Wix free site: design for free, pay to sell

Wix lets you build a custom site and add products at $0 under its free website tier. However, a free Wix site cannot accept online payments. It functions well as a preview sandbox, but taking sales requires upgrading to a paid plan. See our Wix pricing guide for upgrade details.

Hosted ecommerce platforms and domain registration

Standalone ecommerce platforms generally require paid plans to sell online:

• Shopify: Offers a trial promotion (3 days free, then $1 per month for 3 months). Shopify Basic then renews at $29 per month billed yearly or $39 billed monthly. Shopify includes built-in features like Shopify Email with 10,000 free emails per calendar month (additional sends cost $1 per 1,000 emails, while abandoned checkout automations are always free). Details are in our Shopify pricing guide.
• Domains: Custom domains carry renewal costs. For instance, Hostinger standalone .com renewals cost $19.99 per year ($1.67 per month) after the first year, including free WHOIS privacy. Squarespace annual plans include a free custom domain for the first year, which renews at standard rates plus taxes thereafter. Wix paid plans also include a free domain for 1 year. See our domain registrar guide and domain setup guide.

Who should pick something else

Free tools provide a great runway, but they are not the best fit for every business model:

• Stores doing over $12,250 a month in online card sales: Move off Square Free. Square Plus ($49/mo) or platform gateways like Shopify Payments (2.9% + 30¢ on Basic) save 0.4% per order, covering the monthly fee once volume passes $12,250.
• Fast-growing stores with large subscriber lists: If you expect over 250 subscribers in your first month, free tiers will lock campaigns quickly. Budget for MailerLite Comfort ($12/mo) or Omnisend Standard ($16/mo).
• Founders who want an all-in-one dashboard: If juggling separate logins feels overwhelming, Shopify Basic ($29/mo yearly) bundles hosting, payments, and 10,000 monthly marketing emails. Compare platforms in how to choose an online store platform.

Common mistakes when using free tools

1. Paying for lower transaction rates before sales justify it. Upgrading payment plans to chase a 0.4% fee reduction costs more than it saves until you hit $12,250 monthly for Square Plus.
2. Getting locked out of email campaigns during a launch. MailerLite locks outgoing sending once your contact count exceeds 250. Monitor your list before running promotions.
3. Assuming free shipping software means free postage. Pirate Ship charges no software fees, but carrier postage must still be paid for every package. Factor postage into your pricing model using our product pricing guide.
4. Stacking multiple free marketing apps that do the same job. Connecting two separate email and popup tools clutters your site code and divides your contacts. Pick one tool and master its automations first. Our app audit guide explains how to keep software lean.

What to do this week: a 4-step setup checklist

1. Pick your core sales channel. Decide whether you are building on a dedicated storefront platform or testing products via in-person pop-ups with Square Free. If starting fresh, check our practical launch checklist and step-by-step launch guide.
2. Open a free shipping account. Register on Pirate Ship to access discounted USPS and UPS rates with zero monthly fees. Order free Priority Mail boxes from the USPS store if shipping boxed items.
3. Connect a free email tool. Set up MailerLite Free (for 2,500 monthly sends) or Omnisend Free (for 24/7 live support) to collect customer emails on your site. Configure a simple welcome flow using our welcome and abandoned cart email guide.
4. Track unit economics on every sale. Calculate your true profit margin after carrier postage and card fees. Use our profit per order calculator to ensure each sale leaves cash in your account before spending on paid software upgrades.
