1. Export a CSV, import it into Sheets

All three platforms can export your sales as a CSV file. In Google Sheets, File → Import → Upload then turns each file into a tab, and Insert → Pivot table gives you totals by month or product.

Gumroad

On the Sales tab, click the Export icon, pick a date range and click Download. To export one product, select it with the Filter icon first. Other filters on the page don't apply to the export. If the file isn't ready straight away, Gumroad emails it to you (Gumroad: the sales dashboard). One catch: the dashboard uses your time zone but the CSV uses UTC, so Gumroad suggests adding a one-day buffer at each end of the range (Gumroad: sales analytics).

Polar

Polar added a CSV export of orders to the dashboard, and it respects the product filter you've set (Polar product updates). We haven't seen the file itself, so we can't tell you exactly which columns it has.

Lemon Squeezy

The Export button on the Orders page generates a CSV and emails it to the store owner. Lemon Squeezy documents the columns, including product, variant, country, subtotal, discount, tax, total, tax name and rate, and the order date in UTC (Lemon Squeezy: Exporting orders). Two things to know: the money columns are in US-dollar cents (so $10 shows as 1000, and you divide by 100), and the documented columns include the buyer's name and email. The documented list doesn't include a fee column.

Best for: a monthly or yearly check, or handing figures to an accountant. It's free and nothing else touches your data. Not great for: anything you want kept up to date, or combining platforms, since each file has its own layout. The files also hold buyer emails, so think about who you share the sheet with.

2. Your own Apps Script (free script for Polar)

Every Google Sheet comes with Apps Script (Extensions → Apps Script), which can call these platforms' APIs with your own token. Here's a free script for Polar, which we picked because Polar lets you make a token that can only read orders. It copies the last 90 days of orders into a tab called "Polar orders".

/**
 * Polar -> Google Sheets: your organization's orders from the last 90 days.
 * Free, no add-on. Paste into Extensions > Apps Script in your spreadsheet.
 *
 * Setup:
 *  1. Polar dashboard > your organization's Settings > Developers > New Token.
 *     Pick an expiry date and select ONLY the orders:read scope.
 *  2. Apps Script: Project Settings (gear icon) > Script properties > add
 *     POLAR_TOKEN = that token.
 * Keeping the token in a script property, not in the code, means it isn't
 * visible to people you share the code with. Anyone who can edit the script
 * project can still read it, so keep that list short.
 *
 * Polar amounts are in cents; this writes them as 12.34 in each order's own
 * currency. Nothing is converted between currencies, and no totals are made.

}

1. In Polar, open your organization's Settings, scroll to Developers and click New Token. Give it a name and an expiry date, and select only the orders:read scope (Polar: Organization Access Tokens). The List Orders endpoint needs just that scope (Polar API: List Orders).
2. Paste the script into the Apps Script editor and save.
3. Project Settings → Script properties: add POLAR_TOKEN with your token.
4. Select importPolarOrders and click Run. Google asks you to authorize the script the first time.
5. To refresh it automatically, open Triggers (the clock icon) and add a daily time-driven trigger for importPolarOrders.

How it works: it calls GET https://api.polar.sh/v1/orders/ with your token as a Bearer header, 100 orders per page (the maximum), and keeps going until the last page that Polar's pagination.max_page reports (Polar API overview). Polar allows 500 requests a minute per organization and answers 429 with a Retry-After header if you go over (Polar), so the script waits a little between pages and honours that header. Polar sends amounts in cents, and the script divides by 100. Text that could run as a formula is stored as plain text. Buyer emails are left out unless you set INCLUDE_EMAILS = true.

Honest limits:

• We tested this script against a simulated Polar API built from Polar's documentation, not against a live Polar account. Treat it as a starting point and compare the first result with your Polar dashboard.
• You get raw orders: no monthly totals, no "what I kept" column and no refund matching. Polar notes that its payment fees aren't returned when you refund (Polar: refunds), which matters if you calculate earnings yourself.
• Polar uses dated API versions and says to pin one in production with a Polar-Version header. Without it, requests use the "Current" version, which changes every quarter. Each version lasts about nine months (Polar: API versioning). The script doesn't pin a version, so a future change could break it. You can add the header, but a pinned version eventually stops working too.
• Script properties are readable by anyone who can edit the script project (Google: Properties service), so keep editors to people you trust with the token. On a consumer Google account, Apps Script allows 6 minutes per run and 90 minutes of trigger runtime a day (Google: Apps Script quotas).

Gumroad or Lemon Squeezy instead? The same approach works with a few changes:

• Gumroad: GET https://api.gumroad.com/v2/sales "retrieves all of the successful sales", takes after and before dates, and pages with page_key / next_page_key (Gumroad API). You get a token by creating an application in Gumroad and clicking Generate access token (Gumroad help). Gumroad's docs list OAuth scopes such as view_sales, but don't say which scopes that generated token has, so treat it as a full-access password.
• Lemon Squeezy: GET https://api.lemonsqueezy.com/v1/orders with a Bearer API key and the application/vnd.api+json headers. Pages go up to 100 orders (page[size]), and you follow links.next (Lemon Squeezy: requests). Orders come newest first, and the documented filters are store, email and order number, with no date filter (Lemon Squeezy: list orders), so stop once you reach orders older than you need. API keys are valid for a year (requests), and the limit is 300 calls a minute (Lemon Squeezy API). Unlike its CSV export, the API gives amounts in the order's own currency, with USD copies in fields like total_usd (the order object).

Best for: one platform, a little code, and wanting something free that you fully control.

3. A general API connector

Connector add-ons and data-pipeline services can call almost any REST API. We didn't find a ready-made Gumroad, Polar or Lemon Squeezy source in either of the two below, so you set up the request URL, the token header and the paging yourself, using the API details in option 2.

API Connector (Mixed Analytics)

A Google Sheets add-on for calling APIs, with pagination handling on every plan. Prices in USD (API Connector pricing):

• Free: 100 requests/month, 3 saved requests, 1,000 rows, no scheduling.
• Starter: $15/month ($12/month billed annually), 2,500 requests/month, daily scheduling.
• Business: $29/month ($23/month billed annually), 60,000 requests/month, hourly scheduling.

Coupler.io (JSON importer)

Coupler.io's source list doesn't include Gumroad, Polar or Lemon Squeezy (Coupler.io pricing), and its pages for those integrations redirect to sign-up. Its JSON importer takes any API URL with custom headers and can refresh on a schedule (Coupler.io: JSON to Google Sheets). The Free plan has manual refresh only. Starter is $32/month ($24/month billed annually) with daily refresh and 5,000 rows per run. We didn't test whether it can follow each platform's paging.

Better fit than ours if you already use one of these for other APIs, or want to pull fields we don't. Watch out for: you build the requests, and the output is raw, so fees, refunds and monthly totals are formulas you write. Like any connector, it needs your token, so check how it stores it.

4. Zapier, Make or IFTTT

Automation tools react to events, for example "a new sale happened", and run an action such as "add a row to a sheet".

Zapier

• Gumroad: triggers for Sale, Refund, Cancellation and New Product (Zapier: Gumroad + Google Sheets).
• Lemon Squeezy: triggers including Order Created, Order Refunded and subscription events (Zapier: Lemon Squeezy + Google Sheets).
• Polar: triggers only, such as Order Created, Order Paid and Order Updated (Zapier: Polar). Polar says it has focused on triggers for now (Polar docs).
• On the Sheets side there's Create Spreadsheet Row. Zapier's Free plan has 100 tasks a month and two-step Zaps. Professional starts at $19.99/month (Zapier pricing).

Make

Make's own Gumroad app (maintained by Make) includes a List Sales module, so a Make scenario can fetch past sales as well as react to new events (Make: Gumroad). For Lemon Squeezy, Make lists community-built apps, some sold by third parties (Make: Lemon Squeezy). We didn't find a Polar app in Make's integrations directory. The Free plan includes 1,000 credits a month with a 15-minute minimum interval between runs (Make pricing).

IFTTT

There's a ready-made "Log Lemon Squeezy orders to Google Sheets" applet (IFTTT).

Better fit than ours if you want something else to happen on each sale too (a Slack message, an email-list tag), or you only need a running log of new sales. Watch out for: a "new sale" automation adds rows from the day you turn it on. It doesn't import your history, and when a sale is refunded later, the original row doesn't change unless you build that step as well.

5. Earnings by Small Rows (ours)

A Google Sheets add-on for exactly this job. You paste a token for each platform you sell on, and it builds a Sales tab with one row per order, a Monthly Summary by platform and currency, and, on Pro, a Tax Collected tab and a Gumroad Payouts reconciliation. After the first full pull, each sync re-reads the last 35 days to pick up refunds. Ko-fi and Payhip, which have no API for reading sales, can be added on Pro by importing their CSV exports.

• Free: one platform, the last 90 days, manual sync, Sales and Monthly Summary.
• Pro (planned): US$6/month or US$54/year. All platforms in one sheet, full history, hourly or daily refresh, the Pro tabs and imports.
• These are planned launch prices and may change before launch.

Limits we want you to know: Lemon Squeezy's API has no fee field, so its fee is an estimate (the 5% + 50¢ base fee; the real fee can be higher with international, PayPal or subscription surcharges, per Lemon Squeezy: fees). The Ko-fi and Payhip column mappings haven't been checked against real exports. And as of 2026-10-05 the add-on has only been tested against simulated APIs.

Better fit than the others if you sell on two or three of these platforms, want your whole history with fees, refunds and tax in your own Google Sheet, and don't want to maintain a script. Not a fit if you need Stripe or Paddle, want charts or a phone app, need a tool with a track record and reviews, or only look at the numbers once a year (option 1 is free).

Product page & pricing · All limitations

Don't need a spreadsheet?

If what you want is a revenue dashboard rather than rows you can work with, there are apps built for that. A few that list Gumroad, Lemon Squeezy and (for some) Polar: SaneSales (free and open source, for Apple devices; Lemon Squeezy, Gumroad and Stripe), RevOne (a Mac app; Stripe, Gumroad, Lemon Squeezy, Polar and others), Owelet (a web dashboard; Stripe, Gumroad, Lemon Squeezy and more) and MyOpcs (a web dashboard; Stripe, Gumroad and Lemon Squeezy). We haven't tried them. Check their pricing pages, since plans change.

A note on Lemon Squeezy: in January 2026 its team said it is building Stripe Managed Payments and plans to give Lemon Squeezy users a way to migrate (Lemon Squeezy 2026 update). Whatever you build on its API, keep an eye on that.
