The same factors, rated the same way, for every tool.

I'll state my position first, because it's the whole point of a page like this. I research and rate every tool in the Index myself, and no commercial relationship decides the order. Some vendors pay for featured placement — I'll come to that — but it doesn't move their number. If it did, this would be an ad, not an index.

The Index Score, in one line

Each tool gets a single number from 0 to 100: the Index Score. It's the equal-weighted mean of four factors, each scored 0–100. No secret weighting, no thumb on the scale — add the four, divide by four. That's deliberate: the headline number and the factor bars on a comparison page can never disagree, because the headline is the average of the bars.

The four factors we score

Strip away each vendor's invented vocabulary and they're all doing the same handful of jobs. We score that across four factors, weighted equally.

Each factor is scored on a 0–100 scale anchored to what the factor measures, not graded on a curve against the field:

• Features & depth rates how complete and capable the tool is for its job — not whether a feature is listed, but how far it actually goes, from a basic email blast at the bottom to a full automation suite at the top.
• Integrations starts from how many of the eCommerce platforms a tool natively connects to as a first-class integration, then is adjusted for the wider app ecosystem around it — a tool that only reaches your store through a brittle third-party connector doesn't score the same as one built around it.
• Ease of use rates how quickly you can set the tool up and live with it day to day — a tool you can configure and run yourself sits high; one that needs an implementation project before it earns its keep sits lower.
• Value for money is capability per dollar at a realistic working configuration — not the sticker price, but what you actually pay once seats, contact or order volume and add-ons are in, set against everything the tool delivers.

The scores are editorial judgement calls, made the same way for every tool and against verifiable inputs — live vendor pricing, published platform integrations, and documented capabilities — so they're consistent and contestable rather than a black box. They reflect what the vendor publishes, not a hands-on test on a live store. If you think one is wrong, the numbers are challengeable.

The three categories

“eCommerce tool” covers three genuinely different jobs. Every tool in the Index belongs to exactly one, and we never pretend a shipping app is competing with an email platform. The category sets your expectations; the Index Score tells you how well the tool does its job.

• Email, SMS & marketing automation. Win repeat orders with email, SMS and automation built for store data.
• Inventory, ERP & order management. Keep stock, orders and channels in sync across every place you sell.
• Shipping & fulfillment. Print labels, cut shipping costs and get orders out the door faster.

The platform matrix

The integrations factor and the matrix on the home page both run off the same set of eCommerce platforms. A tick means the tool natively integrates with that platform as a first-class connection — not that it can fire a webhook into something that does.

• Shopify
• WooCommerce
• BigCommerce
• Adobe Commerce (Magento)
• Wix / Squarespace
• Amazon

What the bands mean

The score badge on a card translates the number into plain language. The thresholds are tuned to this dataset's spread, which sits lower than the inflated headline numbers vendors quote about themselves — an 88 here is earned.

Who does the scoring

One person, on purpose. I'm Marcus Taylor — founder and lead reviewer at Ecommerce Software, part of Venture Harbour. I set the methodology and rate every tool myself, so there's one consistent hand on every score and a single name to hold accountable when one looks wrong. There is no anonymous panel and no ghost-written verdicts. More about why the Index exists is on the about page.

Kept current

Pricing, platform coverage and feature sets in this market move fast. We re-check the data and re-score where something material has changed. The current numbers were last refreshed on 16 June 2026; the date sits on every page so you always know how fresh the data is.

How we make money — and how we don't

Ecommerce Software is reader-supported, in two honest ways. Some links are affiliate links, and select vendors pay for featured placement. Anything paid is labelled PARTNER and carries rel="sponsored", every time.

Neither one buys a better number. A vendor can pay to be visible; they cannot pay to rank higher or nudge a factor up — those come from the rating and nothing else. The day that line blurs, the Index is worthless, so I keep it bright.

Found something wrong?

Numbers drift, and I won't always catch a change on day one. If a price or an integration claim looks off, tell meand I'll re-check it against the vendor's live site. The Index is only useful if it's current.
