Custom E-commerce vs Shopify and Tiendanube

You're about to launch your online store and the big question shows up: do you build everything in Shopify or Tiendanube in an afternoon, or do you invest in a custom e-commerce? The right answer depends on your business, not on the trend. For a standard catalog and low volume, a platform like Shopify or Tiendanube is faster and cheaper; a custom e-commerce wins when your business logic doesn't fit a template or when sales volume makes accumulated commissions exceed the cost of your own store. Here's the honest comparison, with no sales pitch in either direction.

Custom e-commerce vs Shopify vs Tiendanube: an honest comparison

Each option is good at something different. This table sums up the differences that actually matter when it's time to decide:

Criterion	Tiendanube	Shopify	Custom e-commerce
Upfront cost	Low (monthly fee)	Low-medium (monthly fee)	High (one-time build)
Per-sale commission	Yes, by plan	Yes, by plan/gateway	No
Time to launch	Days	Days	Weeks to months
Deep customization	Limited	Medium (with apps)	Total
Integration with your ERP/systems	Restricted	Via apps	Total
LATAM payment methods	Very good	Good	Whatever you want
Maintenance	Handled by the platform	Handled by the platform	Your responsibility
Special business logic	No	Hard	Yes

The takeaway isn't "one is better." It's: platforms give you speed and zero maintenance in exchange for limits and commissions; custom development gives you total freedom and zero per-sale commission in exchange for a higher upfront investment and technical responsibility.

Another way to see it: a platform is like renting a unit in a shopping mall. Everything's handled, the space works from day one, but you pay rent every month and you play by the mall's rules. A custom e-commerce is like building your own store: it costs more at the start and you handle the maintenance, but it's yours, you do whatever you want, and you don't pay anyone a percentage on every sale. Neither option is bad; they suit different moments in a business.

When it pays to stay on a platform

Let's be clear: Shopify and Tiendanube are excellent, and for most businesses just starting out they're the right call. Stay on a platform if:

• You're validating the business. It makes no sense to invest USD 8,000 in a custom store to sell something you don't yet know has demand. It's the same logic as a web MVP: validate first, scale later.
• Your catalog is standard. Products, variants, cart, checkout. If your operation fits comfortably in that mold, you don't need to reinvent it.
• You don't want to deal with the technical side. The platform handles security, updates, outages, and backups. That has real value.
• You sell low or medium volume. As long as commissions add up to little compared to your revenue, there's no reason to migrate.

To get started in LATAM, Tiendanube tends to be more accessible and better integrated with local payment methods; Shopify wins on app ecosystem and multi-country sales.

When a custom e-commerce pays off

Custom development stops being a luxury and becomes the profitable decision when any of these cases shows up:

• Differentiated pricing or catalogs per customer. A wholesaler that shows different prices depending on the account type doesn't fit a standard store. A distributor we worked with needed exactly this, and no template could solve it.
• Deep integration with your management system. If stock, prices, and invoicing live in your ERP, a custom store syncs in real time without patches or half-baked apps.
• Special sales flows. Complex subscriptions, quotes, configurable products, particular shipping rules. When the logic is the heart of the business, you need custom software.
• Volume makes commissions hurt. Here's the key math: when what you pay in per-sale commissions each month gets close to what it would cost to amortize your own store, custom pays for itself.

The calculation is simple: add up what you pay in per-sale commissions over a year. If that number gets close to the cost of a custom e-commerce, migrating stops being an expense and becomes a saving.

The math of commissions

Here's the point many people don't calculate. A platform charges a fixed monthly fee plus a percentage on every sale. At low revenue, that percentage is small change. But it grows along with your business.

If your monthly revenue rises and you multiply the commission by twelve months, the annual total can be equivalent to several months of custom development. A custom store has no per-sale commission: you pay for the build once and the monthly hosting, and nothing else. That's why custom isn't for whoever is just starting out, but for the business that already has steady revenue and watches commissions eat into the margin.

The concrete exercise: take your monthly revenue, apply your plan's commission percentage, multiply by twelve, and add the platform's annual monthly fee. If that total gets close to what a custom e-commerce would cost, you're already paying for your own store every year without owning it. And unlike the commission, which rises every time you sell more, the cost of custom development is one-time only: the more you grow, the more it favors you.

Beyond cost: what isn't measured in money

There's a factor that comparisons tend to ignore and that weighs as much as commissions: control over your own business. When you sell on a third-party platform, you depend on its rules, its load times, its limits, and its policy changes. If the platform decides to change pricing, restrict a feature, or change how something works, you don't get a vote.

With a custom e-commerce you own the code, your customers' data, and the direction of the product. You can add exactly the feature your operation needs when you need it, without waiting for a third-party app to offer it. That autonomy doesn't show up in a pricing table, but for a business that lives off its online store it's decisive. The flip side, of course, is technical responsibility: with total freedom comes the obligation to maintain.

When a custom e-commerce is NOT worth it

As much as we sell development, there are cases where custom is the worst decision:

• If you're just starting out and haven't validated demand. That's investing thousands of dollars in something untested. Better a platform or an MVP.
• If you don't want technical responsibility. Your own store needs maintenance, monitoring, and security updates. If you don't have a partner for that, a platform takes that weight off your shoulders. We cover it in web application maintenance.
• If your catalog is simple and standard. Paying for flexibility you won't use is throwing money away.

The good news is that it's not a forever decision: a very valid strategy is to start on a platform, validate the business, and migrate to custom when the numbers justify it.

How to decide today

1. Calculate your annual commission on the platform (or the projected one). That's your benchmark.
2. List what the template won't let you do. If the list is long and painful, custom already makes sense.
3. Cross both numbers against your real sales volume.

If after that you see your business has outgrown the templates, at Deepyze we build custom e-commerce integrated with your ERP, with no per-sale commission and with the payment methods you use in LATAM.
