I’ve been comparing ecommerce development companies, and I think I’ve found a reasonably useful way to filter them.

Ignore the homepage.

Ignore awards.

Ignore the polished store screenshots for a minute.

Ask who wants to talk about the boring stuff.

Returns.

Tax rules.

Product data.

Customer accounts.

Order amendments.

Backorders.

Store credit.

Catalog permissions.

ERP mappings.

Admin workflows.

Failed imports.

Release management.

That’s usually where an ecommerce rebuild becomes difficult.

Based on that kind of project rather than purely storefront design, this is the shortlist I’d start with.

1. Zoolatech

I’d put Zoolatech first when the commerce platform has to fit into an existing technology environment rather than replace everything around it.

That’s the situation I see a lot of established retailers in.

They already have systems for products, customers, inventory, fulfillment, finance, marketing, and reporting. The new ecommerce layer has to work with all of them without creating another isolated system.

So if I were looking for a Top Ecommerce Development Company for a project with substantial backend engineering and integrations, Zoolatech would be my first conversation.

I wouldn’t automatically put them first for a small standalone store. A focused platform agency could be a much more efficient choice there.

2. Tavano Team

This is a much more specific option.

I’d look at Tavano Team when NetSuite is already central to the business and ecommerce needs to work properly around it.

That changes the project significantly.

You’re not only deciding how the storefront works. You need to understand how customers, products, pricing, orders, and operational data move between commerce and NetSuite.

For a company heavily invested in that ecosystem, specialization may be more valuable than choosing a bigger general ecommerce agency.

3. GoMage

I’d include GoMage when Magento/Adobe Commerce is involved, especially if the question is whether an existing implementation should be improved rather than immediately replaced.

That’s a decision I’d want an agency to justify carefully.

An old Magento store might need a replatform.

Or it might need better architecture, fewer extensions, performance work, cleaner custom modules, and a sensible upgrade strategy.

The agency should be able to explain which one it is.

4. KaarTech

This would be one of the more interesting options for an SAP-heavy retailer.

Once SAP is part of the picture, I’d care less about who has the prettiest ecommerce portfolio and more about who understands how commerce fits into enterprise operations.

B2B would be particularly relevant here.

Things like account structures, negotiated pricing, purchasing rules, approvals, credit, and procurement workflows can make B2B commerce fundamentally different from a normal consumer store.

5. Capital Numbers

I’d put Capital Numbers in the broader development category.

Potentially worth considering when the requirement includes ecommerce plus custom software, integrations, migration, or related web/mobile work.

This type of company can make sense when there isn’t one dominant platform specialization driving the project.

The tradeoff is that I’d ask for very specific evidence of experience with the exact architecture involved rather than accepting broad “we work with ecommerce” credentials.

6. Real Agency

More interesting to me when the project is closer to the customer-facing side of ecommerce.

Shopify, Magento, BigCommerce, migration, UX, conversion, and ongoing store development are areas where I’d consider them.

This could be a better fit for a retailer whose backend is relatively stable but whose commerce experience needs serious work.

Not every project needs a huge systems integrator.

Sometimes the problem really is the store.

7. Algoworks

I’d investigate Algoworks when Salesforce is deeply involved in the customer or commerce environment.

A retailer already using Salesforce for customer data, service, automation, or related workflows has different integration requirements from one running a mostly independent ecommerce stack.

Again, I’d make the shortlist conditional on the actual architecture.

I wouldn’t choose a Salesforce-heavy partner simply because Salesforce happens to appear somewhere in the company’s stack.


The exercise I’d give these companies is pretty simple.

I’d send them a one-page description of the current business and ask:

What would you need to understand before recommending a platform?

That question alone could probably remove several companies from the shortlist.

A good answer should lead to questions.

How are products created?

Who controls prices?

Where are promotions configured?

Can customer service modify an order?

How do returns work?

Can an item be returned to a physical store?

How are bundles represented?

How are gift cards handled?

Who controls customer identity?

What happens to historic orders?

How often does product data change?

How many people actually administer the store?

Which operations are currently manual?

Which system cannot be replaced?

Those questions aren’t exciting.

But they tell me whether the team is designing an ecommerce system or simply selling an implementation.

I’d also require a few things before approving development.

A real discovery output

Not 80 slides.

I want an architecture diagram, integration list, data ownership map, risks, assumptions, and decisions that still need to be made.

A migration rehearsal

If the project involves a meaningful amount of customer, product, content, or order data, I wouldn’t want production launch to be the first full migration.

Run it before launch.

Measure it.

Find the bad data.

Fix the process.

Then run it again.

Admin workflow testing

Developers naturally test what customers do.

I’d also want someone testing what happens behind the scenes.

Can merchandising create a product correctly?

Can customer service issue the right refund?

Can operations change an order?

Can finance reconcile it?

Can someone schedule a promotion without calling a developer?

A storefront can be excellent while the internal experience is terrible.

Clear customization rules

Every custom feature should answer two questions:

Why can’t the platform handle this?

What will maintaining this cost us later?

There are legitimate reasons to customize.

“There’s a ticket for it” isn’t one of them.

Actual acceptance criteria

“Implement returns” is not an acceptance criterion.

Which products can be returned?

How many days?

Partial returns?

Multiple shipments?

Discounted products?

Bundles?

Gift cards?

International orders?

Store purchases returned online?

That level of detail should exist before the feature reaches QA.

A first-year ownership plan

Who handles platform upgrades?

Who reviews third-party apps?

Who removes dead code?

Who responds when an API changes?

Who owns performance after another 20 apps get installed?

Who keeps the documentation current?

Launch isn’t the finish line for a commerce platform.

It’s when maintenance starts.


So my shortlist would currently be:

  1. Zoolatech — complex commerce engineering and integrations
  2. Tavano Team — NetSuite-centric ecommerce
  3. GoMage — Magento/Adobe Commerce
  4. KaarTech — SAP and enterprise/B2B commerce
  5. Capital Numbers — broader custom ecommerce development
  6. Real Agency — storefront, migration, and conversion-focused work
  7. Algoworks — Salesforce-connected environments

I’d change the order immediately depending on the project.

That’s probably the main problem I have with most “top ecommerce companies” lists.

They rank vendors before defining the problem.

A $50M B2B distributor running SAP shouldn’t have the same shortlist as a DTC brand migrating to Shopify.

And neither should use the same criteria as a retailer trying to replace a heavily customized commerce platform that has been running for ten years.

Has anyone found a good way to test this during vendor selection?

I’m especially interested in questions that exposed weaknesses before the contract was signed rather than six months into development.
