We built Gorilla ROI before "ecommerce data connector" was a recognized category by people. Of the tools on this list, we paid for and ran Supermetrics for an extended test: two months, 50 SKUs, 200 daily orders. The rest we evaluated through documentation, user reviews, and public pricing. The tools below cover four categories: broad marketing data, agency reporting, spreadsheet-first connectors, and ecommerce operational data.
You're here for one of four reasons. The base plan only sends data to Looker Studio, and getting it into Google Sheets requires upgrading to the Pro plan at $199.95/month. You need more sources than Power My Analytics's ~45 cover. You want a free tier before committing. Or you're an ecommerce seller who discovered the Amazon connector pulls ad metrics rather than the full Seller Central dataset.
If you need FBA inventory levels in a spreadsheet, a tool built to pull ad data for agency clients won't get you there.
Best for: High-volume marketing data with the widest connector libraryPrice: From $37/month (1 output per plan)
Supermetrics has the most connectors of any marketing data tool at 150+, more than three times what Power My Analytics offers. It sends data to Looker Studio, Google Sheets, BigQuery, Snowflake, Power BI, and Excel. If you're leaving Power My Analytics because of gaps in less common ad platforms or sales tools, Supermetrics covers more sources than anything else in the category.
Each plan covers one output only, and adding a second requires a full second subscription. Power My Analytics has the same restriction, just with fewer sources. Entry price is lower at $37/month, but a realistic agency setup with two outputs and multiple sources lands at $400/month before add-ons.
For Amazon seller data specifically, Supermetrics handles Amazon Advertising well and Seller Central shallowly. Large Seller Central queries timed out repeatedly in our two-month test at 200 daily orders across 50 SKUs.
Covers: 150+ marketing and advertising sources, Looker Studio, Google Sheets, BigQuery, Snowflake, Power BI, Excel
Stops at: One output per plan; full Amazon Seller Central operational data beyond advertising metrics
Best for: Agencies needing all outputs on every plan at lower cost
Price: From $15/month per account (all outputs included)
Porter Metrics fixes the one-output-per-plan problem that both Power My Analytics and Supermetrics have. Every Porter plan includes Looker Studio, Google Sheets, Power BI, and BigQuery with no extra charge to add an output. At $15/month for one account, you get all four, a combination that costs $199.95/month at Power My Analytics.
Porter covers 25+ sources versus Power My Analytics's ~45. If your stack includes less common platforms, Porter has gaps. The pricing model is the real advantage, along with automatic combining of data across sources: dates, campaign names, tracking parameters, and ad spend are unified automatically rather than requiring manual work inside Looker Studio.
Porter is built for marketing teams and agencies. It covers Shopify and Amazon at an advertising level only. Seller Central operational data covering inventory, fee detail, and settlement reconciliation is outside its scope.
Covers: 25+ marketing sources, all outputs on every plan, automatic cross-source combining, 50+ Looker Studio templates
Stops at: Fewer sources than Power My Analytics; full Amazon Seller Central operational data
Best for: Pulling sales, customer, and business data into Google Sheets or Excel
Price: Free tier; Starter $49/month; Pro $99/month (all outputs on all plans)
Coefficient connects Google Sheets and Excel to 100+ business tools including Salesforce, HubSpot, databases, ad platforms, and more. Where Power My Analytics starts with the reporting output and works backward, Coefficient starts with the spreadsheet. You pull data from your sources directly into a Google Sheet on a schedule, and you can push changes back from the sheet into Salesforce or HubSpot if needed.
The free tier covers 3 sources with 50 automated monthly refreshes, which Power My Analytics does not offer. The Starter plan at $49/month adds daily auto-refresh and multi-user support, and the Pro plan at $99/month adds unlimited rows, hourly refresh, and 6+ sources across all outputs.
Coefficient is stronger for sales pipeline, customer records, and business operations data. Power My Analytics is stronger for marketing channel reporting. If you need Salesforce data or HubSpot contacts in Google Sheets, Coefficient handles that job.
Covers: 100+ connectors including sales tools, databases, ad platforms; Google Sheets and Excel; all outputs; push-back to source available
Stops at: Marketing-specific cross-source combining and attribution; full ecommerce operational data
Best for: Tracking which ads drove a sale across a customer's full journey
Price: Free tier (1 source); from $19/month
Windsor.ai is the only tool on this list that tracks every ad, email, and channel a customer touched before buying and assigns credit across all of them. No other tool here does this at under $100/month. With 325+ sources, it covers more than seven times what Power My Analytics offers. The free plan covers 1 source with 5 million monthly customer journeys tracked. The Basic plan at $19/month adds 3 sources and 75 accounts.
Setting Windsor up takes real work. You choose the data structures, select the fields you want, and map everything to your output manually. You will run into fields that stop working and silent data failures under heavy use in BigQuery, which comes up repeatedly in user reviews. If you're comfortable with databases and data engineering, Windsor is powerful. If you want a setup that works out of the box without configuration work, Windsor is the wrong fit.
Covers: 325+ sources, free tier, cross-channel customer journey tracking, all major outputs including BigQuery and Snowflake
Stops at: Ready-to-use setup for non-technical teams; full Amazon Seller Central operational data
Best for: Scheduled data pulls into Google Sheets with the widest source coverage
Price: Free tier (100 rows/run); from $49/month
Coupler.io has 400+ sources, nearly ten times what Power My Analytics offers, and a 4.9/5 rating on G2 from 900+ reviews. It is built for teams that need data in spreadsheets rather than Looker Studio. You set up the schedule, any transformations you need, and where the data goes, all from a visual interface without writing code.
The free tier covers 100 rows per run with no auto-refresh and one active connection, enough to test before committing. The Personal plan at $49/month adds daily refresh and 3 accounts, and the Professional plan at $132/month adds 15 accounts and data transformation tools.
Coupler's strengths over Power My Analytics are connector breadth, a free tier, and Google Sheets as the primary output rather than an upgrade. Where it falls short: no ready-made marketing report templates, and data arrives as raw rows your team then shapes into reports.
Covers: 400+ sources, Google Sheets and Excel as primary outputs, transformation tools, free tier
Stops at: Ready-made marketing dashboards; full ecommerce operational reporting
Best for: Budget marketing data with a free plan and high user satisfaction
Price: Free tier; Starter $39/month
Dataslayer scores 4.8/5 on G2 across 295 reviews, the highest in this category. It covers the same marketing sources as Supermetrics at a lower price: per source, per account, per output, starting at $39/month versus Power My Analytics's $49.95/month. The free plan covers 1 source, 1 account, and 1 output, which is enough to test a connection before committing.
Connector count is similar to Power My Analytics at 51 versus ~45. The meaningful difference is cost and Google Sheets access: the $39/month entry plan includes Google Sheets as an output, where Power My Analytics requires the $199.95/month Pro plan for the same. If you run standard marketing reporting across Google Ads, Meta, and common ad platforms and want to pay less and start free, Dataslayer covers the job. Cross-source combining and AI analysis require the Advanced plan at $139/month.
Covers: 51 marketing sources, free tier, Google Sheets and 12 other outputs, Looker Studio, BigQuery
Stops at: Cross-source combining on entry plans; fewer sources than Supermetrics, Windsor.ai, or Coupler.io
Best for: Amazon, Shopify, and Walmart operational data in Google Sheets
Price: $99/month
We built Gorilla ROI because we were the ones sitting with our heads in our hands late at night, manually exporting reports and fixing broken spreadsheets. Our connection pulls Amazon, Shopify, and Walmart account data directly into Google Sheets automatically, without csv exports.
The job is different from every marketing data tool on this list. Those tools pull ad performance across channels into a reporting view. We pull what actually happened in your store: orders, units sold, FBA inventory levels, refunds, fees covering 156+ Amazon fee types, and settlement reports, all structured into the sheet your team already works from.
If the question your team is trying to answer first thing in the morning is "what sold, what's running low, and what fees hit the account," that's what we're built for. Power My Analytics answers "how did the ad spend perform across channels."
You're the right fit if you already sell, your team runs decisions from Google Sheets, and the current process involves downloading and pasting csv exports every week. We replace that loop.
If you're earlier stage and a weekly manual export still takes under 20 minutes, the subscription won't pay for itself yet. Come back when the data retrieval is the bottleneck.
Covers: Amazon, Shopify, and Walmart operational data: sales, inventory, fees, refunds, settlements, PPC, pulled automatically into Google Sheets
Stops at: Ad platform attribution, Looker Studio outputs. dashboards and visual UI
Are you reporting ad performance to clients, or running your own ecommerce operation from a spreadsheet?
Yes, but only on the Pro plan at $199.95/month. The base Business plan at $49.95/month sends data to Looker Studio only. If Google Sheets is your primary output, factor the Pro plan cost into the comparison before choosing.
Dataslayer at $39/month includes Google Sheets on the entry plan. Porter Metrics at $15/month per account includes Google Sheets alongside all other outputs. Coefficient has a free tier with Google Sheets access and a Starter plan at $49/month.
Coupler.io at 400+ sources, followed by Windsor.ai at 325+, then Supermetrics at 150+. Power My Analytics covers ~45 sources, which handles the most common marketing platforms but leaves gaps for less common tools.
For Amazon advertising reporting inside Looker Studio or client dashboards, yes. For sales by product, inventory levels, fee breakdowns, and settlement reconciliation, the Amazon connector covers ad metrics rather than the full Seller Central dataset. If you need that depth, you need a different tool.
Yes. If you manage Amazon advertising for a brand and need both a client-facing ad performance view and an internal operations workbook, Power My Analytics and Gorilla ROI run in parallel without conflict.
