Pricing

Charge for resource usage. Never for success.

Start free. Pay only when you consume storage, email, or API requests. Zero transaction fees on every tier. Payments flow customer to merchant, never through Mercemur.

Start free

Free

Launch ready

No credit card required. Validate your store on Free, then move into Growth only when usage becomes real.

Growth plan

Starting at $5/month

Transaction fee

0% on every tier

No platform transaction fees on any plan

Free tier includes custom domain from day one

Growth includes bundled credit before overages start

Enterprise adds migration, infra, and custom delivery

Why it works

Pricing built to stay aligned with the merchant.

Most ecommerce platforms charge you twice: a flat fee before you have traction, then a percentage of each order after you do.

Mercemur flips that model. Free stays free, Growth starts at $5/month, and Enterprise becomes a scoped annual contract only when your operation needs it.

You sell. You keep what you earn. Mercemur only charges for the resources you actually consume.

Plans

Three clear tiers, with room to grow.

The content stays the same, but the structure should make choice easier: start free, move into measured growth, then step into tailored infrastructure when scale demands it.

Zero transaction fees, explained.

Mercemur never inserts a platform fee between your revenue and your payout.

Most ecommerce platforms take a percentage of every order. Even the ones that do not call it a transaction fee usually slip one in as a platform fee or surcharge. The cost compounds with every successful sale.

Mercemur is built to never charge transaction fees. Customers pay you through Stripe or Razorpay. The gateway charges its published rates directly to your account. Mercemur gets nothing on the order.

What Mercemur does charge for is platform resource usage. The Growth tier starts at $5/month, with transparent overages only when you exceed the included storage and email bundle, plus a flat per-request rate.

Merchant payout flow

Direct to gateway

Platform cut on orders

None

What gets billed

Measured resources

Growth metering

What you actually pay for on Growth.

Only three resources are metered above the included bundle, and each one is visible in real time from your admin dashboard.

20 GB included

Storage

Product images, digital product files, blog images, and video. Above 20 GB, pay $0.10 / GB per month.

500 sends included

Email sends

Transactional and marketing sends share the same meter. Above 500, pay $0.005 / send.

Pay-as-you-go

API requests

Sum of admin and storefront API calls served by Mercemur. $1.20 / million flat rate, no included floor. Real-time meter visible in the dashboard.

Not metered

What never shows up on your bill.

Always free
Transaction fees on orders (zero, on every tier)
Product categories, tags, and types (organize however you want)
Digital products and license keys (sell downloads, never billed)
Gift cards (issue and redeem at no extra cost)
Returns, exchanges, and refunds (full order management, no per-order fee)
Manual orders (sell over the counter, never billed)
Customer groups and segments (target however you like)
Product reviews and ratings (collect unlimited feedback)
Custom domain and SSL (bring your own domain, no charge)
Multiple payment providers (connect Stripe, Razorpay, or Dodo, never billed)
Order and customer CSV exports (pull your data anytime)

Billing principle

You pay for platform consumption, not a cut of your sales.

Storage, email, and API requests are the metered dimensions. API requests cover the backend calls behind storefront and admin activity, billed at a flat per-million rate so heavy usage stays predictable. We never take a percentage of an order.

Billing flow

How Growth billing works month to month.

The process is intentionally simple so merchants can forecast cost without digging through docs.

1

You subscribe to Growth. Starting at $5/month, billed monthly.

2

Every unit you use is metered: $0.10 / GB storage, $0.005 / send, and $1.20 / million API requests.

3

You sell, ship, and run campaigns while real-time meters track every unit.

4

The real-time dashboard shows current period usage and where you are likely to land by month end.

5

If your usage stays below $5/month, you pay the $5 monthly minimum and nothing more.

6

If your usage exceeds the minimum, you pay only for what you actually used at the rates above.

7

At month end, you pay the metered total in one charge.

Upgrade guidance

When to move up a tier.

Free to Growth

Upgrade when usage starts becoming operational.

You are pushing past 1 GB of storage
You are sending more than 500 emails per month
You need a real-time usage dashboard
You want the headroom of a 20 GB storage bundle

Growth to Enterprise

Upgrade when the platform becomes core infrastructure.

You need a custom storefront design beyond the builder
You need custom features built for your operation
You are migrating off a legacy platform and need migration assistance
You need dedicated infrastructure with uptime guarantees
You need a named account manager with 24/7 support
You require security hardening, audits, or compliance attestations
You operate in a regulated industry
Scenarios

A few common fits.

These examples help merchants map their operating shape to the right tier without overspending early.

Free

Solo founder with their first store

No revenue yet, 1 GB storage and 500 emails covers a starter catalog and welcome series. No card required, no risk.

Growth starting at $5/month

Growing brand with 50 products and a weekly newsletter

Pay only for what you use: storage at $0.10 / GB, emails at $0.005 / send, and API requests at $1.20 / million. Below the $5 minimum, you just pay the minimum.

Growth, usage-based

High-traffic brand sending bulk campaigns

Heavy email volume and traffic show up directly as $0.005 / send per email and $1.20 / million API requests. The dashboard shows exactly what is accruing.

Enterprise

Multi-brand operator running 5 brands

Five brands need dedicated infrastructure, migration support, custom features, and an account manager. Annual contract gives a tailored quote.

Growth

Software vendor selling license keys

Digital products work on every tier. The 1 GB storage on Free is small for software installers, so Growth's 20 GB makes sense. Transactional emails for license delivery fit the 500 bundle.

Frequently asked questions

No. The Free tier is forever free with no card required. A payment method is only needed when you move to the Growth plan or sign an Enterprise contract.

Growth includes a 20 GB storage + 500 email bundle on the $5/month monthly minimum. Above the bundle, you pay only for what you use: storage at $0.10 / GB, email at $0.005 / send, and API requests at $1.20 / million (no included floor). If metered usage stays below the minimum, you pay the minimum. Track every unit in real time from your dashboard.

No. Mercemur charges zero transaction fees on every tier. Payments flow directly from your customer to your gateway (Stripe or Razorpay). We never touch your funds, hold escrow, or take a revenue cut.

Enterprise is a custom annual contract for brands that need dedicated infrastructure, guaranteed uptime, ERP/CRM integrations, security hardening, migration support, and a named account manager with 24/7 support. Pricing is tailored to your scale and scope, talk to sales for a quote.

Yes. Up or down, any time. Changes apply at the next billing cycle. Data stays exactly where it was.

Yes. Cancel any time on Free or Growth. No long-term contract. Enterprise plans are typically annual.

Stripe and Razorpay charge their own published rates directly to your account. Mercemur does not see those fees or add to them.

There are no per-order fees on any tier. Payments succeed or fail through your gateway. Mercemur charges nothing on either outcome.

No. The Free tier is $0. The Growth tier starts at $5/month plus optional per-unit overages on storage, emails, and API requests. Enterprise is a negotiated annual contract. Everything appears in your dashboard before it hits your card.

Overage charges accumulate at the per-unit rates ($0.10 / GB storage, $0.005 / send email, $1.20 / million API requests). At month end, you pay the starting monthly fee plus the overage as a single charge. You do not get bumped to a higher tier without consent.

Yes. They are free Google and Meta services. Mercemur charges nothing extra to integrate them.

Storefront traffic itself is not metered. The backend API calls each page makes while loading (product fetch, cart, customer) are part of the unified API requests meter at $1.20 / million. Static assets and edge cache are not counted.

Free is free indefinitely, so you can use Free to fully evaluate the platform before subscribing to Growth.

No setup fees on Free or Growth. Enterprise includes dedicated onboarding as part of the plan.

Features unavailable on the lower plan stop working at the next cycle. Data is preserved.

Yes. All B2B features (customer groups, draft orders, region-aware pricing) work on every tier.

Prices are quoted excluding tax. Tax is added at billing where applicable.

Yes. Enterprise pricing is tailored. Talk to sales.

Audit your current storage (catalog images, files) and monthly email volume. Compare against the Growth bundle (20 GB storage + 500 emails). If you fit inside the bundle, your cost starts at $5/month. If you exceed it, multiply the overage by the per-unit rate. API requests are billed at a flat per-million rate on top.

Overages cover spikes automatically. Pay only for the resources consumed in that period. No tier bump, no surprise upgrade, no contract change.

Multi-store under one billing relationship is part of the Enterprise tier. Growth is sized for a single brand operation.

No. Those are free Google and Meta services integrated at no extra charge.

Savings example

What zero transaction fees actually saves you

Typical platform with 2% transaction fee

Platform transaction fee charged on every order you process
Stripe or Razorpay gateway fee on top, paid separately to the gateway
Combined fees stack on every sale, so the more you sell, the more you pay
A flat monthly subscription fee on top of all of the above

Mercemur Growth

Zero transaction fee from Mercemur on any order
Stripe or Razorpay gateway fee flows directly customer-to-gateway-to-your-bank, Mercemur never touches it
Starting at $5/month, plus per-unit charges only if you exceed the included storage and email bundle, plus a flat per-request rate
You pay for resources you consume, not for sales you close

The bigger you scale, the more a zero-transaction-fee model compounds in your favor.

A platform that charges a percentage of every sale earns more when you succeed. Mercemur earns the same flat base whether you sell ten orders or ten thousand.

Principles

Resource-based, not success-based.

Resources are real costs

Storage, email infrastructure, and per-request compute are measurable platform costs, so they make sense to meter and pass through.

Sales success is your work

You built the brand, ran the campaign, and served the customer. The platform should not earn a cut of that outcome.

Predictability matters

Starting at $5/month plus visible overage rules is easy to forecast. A transaction fee rises every time you win.

Aligned incentives

Resource-based pricing pushes the platform to optimize delivery and keep your operating cost low as you scale.

Operations
