Questions and answers

Not for one person: the free plan runs everything. Teams: Notion's own plan limits apply.

As soon as your payment clears, your order page (the page you land on after paying; its link is also in your order email) shows a download link for each file, and the same links arrive by email at the address you gave at checkout. Nothing is posted. For Lunith Commerce OS, that is the guide as a PDF in US Letter and A4, a short README, and one zip with all of it, the four CSV import templates included. Your order email also carries your own link to the OS, and page 3 of the guide says how to use it: open it while signed in to Notion, click Duplicate, and the whole system copies into your own workspace. Lost the email? Go to lunithlabs.com/access.

Not with us: there is nothing to sign up to at LunithLabs, and your order email is your way back to your files. Lunith Commerce OS runs in your own Notion account.

On Stripe's checkout page: by card, or another method Stripe shows you there. Stripe handles payment details; we never see them. Prices are in US dollars.

Look in spam or promotions first: it comes from an address you have not had mail from before. If your order page is still open, you can download from there. Or type the address you used at checkout on Find my order (lunithlabs.com/order), and we send your links to it again. If none of that works, write to support@lunithlabs.com from that address.

For as long as the order stands: each click is checked against our record of your order at that moment. Save the files somewhere of your own anyway. If a link ever stops working, open it again from your order email, or use Find my order (lunithlabs.com/order). If that still doesn't work, write to us.

The tools are .xlsx workbooks, each with a PDF guide in US Letter and A4. Lunith Commerce OS arrives as a PDF guide, and your order email carries your own link that copies it into your own Notion workspace. Each product page lists every file in the download.

Whichever matches your paper. US Letter is the standard sheet in the United States and Canada; A4 is the standard in most other countries. Both are in the download, and each is drawn at its own real size rather than scaled from the other.

At 100% or Actual size. Not Fit to page or Shrink oversized pages: those resize the page, and that is what moves content into the edge your printer cannot reach. Print one page first and check it.

Printing the guides at the right size

Yes. The guides read well in any PDF app; nothing in them needs printing.

They are .xlsx files built for Microsoft Excel and Google Sheets, using only functions both support. Numbers can open .xlsx files, but we have not checked ours in it; Google Sheets, free with a Google account, is the safer choice there.

The spreadsheets and your copy of Lunith Commerce OS, yes: they are yours to change. The PDF guides are finished pages to print or read, not documents built for editing.

Lunith Commerce OS works best on a desktop screen, because its tables are wide: a phone is fine for reading a number or adding a row, not for working in it.

The guide has a page of three checks for straight after you duplicate: example sale 1002 should read Net $7.09, the example Etsy row 5 ledger orders, and the example Wedding Seating Kit 4 units sold. If it will not copy, or any of the three is blank, sign in to Notion in the same browser first, then open your own link from your order email again. If it still will not copy, or copies with its numbers blank, write to us with your order reference and what you saw, and we will work with you to get it working.

For every example channel but your own website. The Etsy row carries Etsy's published US-seller figures, the Gumroad row its standard rate, and the Shopify row its US Basic plan with Shopify Payments. Standard US card rate. Premium and international cards cost more; check your payout report. Gumroad uses a standard rate for most sellers, with a lower rate at high monthly volume and custom rates on some accounts. The PayPal, Payhip and Lemon Squeezy rows are estimates read on each platform's own fee page on 9 October 2026: PayPal's US business rate for PayPal Checkout, 3.49% plus $0.49; Payhip's Free Forever plan, 5%, with its two processing cells left empty: Payhip's page says PayPal or Stripe charge their standard rates on top but doesn't list them, so type your own; and Lemon Squeezy's 5% plus 50¢. Each row shows the date its figures were checked and has a link to that platform's fee page in its Fee source cell. Fees change and other countries and plans differ, so check them against your own fee page. It does not work out VAT or sales tax. The own-website row is left at 0% for your payment processor's rate; until you fill it in, that channel nets its gross.

Yes. Add a row on Platforms for any place you sell, such as a marketplace, a social shop, your own site or a stall at a fair, and type its fee rates from its own fee page with the date you checked. Where a platform charges different rates by category, give each rate its own row. Nothing is looked up for you; every rate is one you type.

Open that sale's row in Sales and type what you gave back in its Refund column: the whole amount, or only the part you gave back. Its net drops by that amount and the fees the channel kept stay counted, so that channel's and that product's net show what you kept. For a channel you type into Months, put what you gave back that month in the Months row's Refunds column.

Updates we release for it are free for everyone who bought it, and each one is listed on the updates page. An update is meant to be additive: new properties, views or pages. We avoid renames that break a formula, and the updates page lists every change. You take it by duplicating a fresh copy from the same link; the copy you already have is yours to keep.

Updates

A profit app connects to your store and updates itself, for a monthly fee that often rises with orders or channels. Lunith Commerce OS connects to nothing: you type each sale, or a month's totals from the platform's statement, and it works out the fees and what you kept. You pay once, every channel is on the Platforms table, and the numbers live in your own Notion. If you need it to update itself, a connected app is the better buy.

Your order page and your order email carry your own link to the OS once your payment clears.

Email support@lunithlabs.com. We aim to fix it within 3 to 7 business days of having the details we need to reproduce it, free of charge.

How fixes work

No. It has example fee rows for your own website, Shopify, Gumroad, PayPal, Payhip, Lemon Squeezy and Etsy, and you add a row for any other place you sell, such as a marketplace, a social shop or a stall at a fair.

Two tools work alongside Lunith Commerce OS today: Offer Math and Unit Cost Sheet, $19 each. The launch steps now live inside the OS as a free Launch guide.

No. There are no clients, invoices, timesheets, proposals or client portals in it. It is built around what you sell, the channels you sell it through, and what each sale kept.

No, it runs the selling side of a business. There are no habit grids, no dated personal pages and no personal budget categories. All ten databases are about selling.

Judge it on the money side: a fee row per channel, fees and net worked out on every order, a monthly-totals route for busy channels, and the effective fee rate and profit after ads on each channel's row. If you already have that somewhere you trust, you do not need this.

Six databases are the core, and four are modules that stay shut until you open them. The guide's Start Here path takes one part a day for seven days, and day one is a single database: your channels and their fees.

Yes. walkthrough.mp4 is in the download itself, not a link to somewhere else. It covers what you are looking at, logging a sale, where the money shows, the listing pipeline, opening a module, and what you can safely change.

Yes. Set a product's Kind to Physical and give it a unit cost, the stock you have on hand and the level you reorder at; on each sale, type the units and the shipping charged and paid. Profit then takes the goods and the shipping off, Low stock ticks when the count falls to the reorder level, and the Stock view and the home page's Stock to reorder list them. It does not raise supplier orders, keep warehouse locations, print shipping labels or handle variants such as sizes, and the stock count is one you type: no sale takes it down.

Yes. The fee arithmetic works the same for one channel as for five, and a second channel is one more row when you add it.

Yes, once. Four CSV templates in the download's zip are headed exactly like Products, Sales, Listings and Expenses, and Notion's Merge with CSV brings a filled one in; the guide's Bringing your numbers in page goes through it. After that it is typed in as you go, and nothing syncs.

No. Every number in it is one you type, order by order or as a monthly total from the platform's own statement. There is no live connection to any marketplace, shop or payment account, no ranking data and no keyword tool. The Keywords field on a listing holds your own notes.

Manual entry, no live sync, no ranking data. Best on a desktop screen.

Every limit, in full

A new row in Sales: pick the product, pick the channel, type the amount, and tick Ad-attributed if the platform charged its ad fee on that order. Fees and net fill themselves in. For a physical product, also type the units and the shipping charged and paid, and the profit after goods and shipping fills itself in too. If a channel has too many orders for that, type its monthly statement into Months instead.

No. It is a one-time purchase: you pay once, and the copy you duplicate into your workspace is yours to keep. Updates we release for it are free for everyone who bought it and listed on the updates page; you take one by duplicating a fresh copy from the same link.

Updates

Because of what is in it: ten related databases under one home page, a fee table per channel, fees and net worked out on every sale, a monthly-totals route, profit after ads per channel, four modules, CSV import templates, and a guide that explains each database and its key formulas. Compared with a simpler tracker, it adds a fee row per channel that you date and re-check, fees and net on every sale, a monthly-totals route for busy channels, a weekly review, a guide to each database and its key formulas, and email support for anything broken. We aim to fix problems within 3–7 business days of having the details we need to reproduce it. If a simpler tracker covers what you need, it is the better buy.

Yes. The intro price of $35.99 runs through Dec 14, 2026. From Dec 15 it's $59.99. Anything you buy stays yours.

All sales are final: you get everything as soon as your payment clears, so there is nothing to hand back. What we promise instead is that it works as described. If anything is broken, unclear or missing, email support@lunithlabs.com. We aim to fix it within 3 to 7 business days of having the details we need to reproduce it, free of charge. We read every message, and when a fix changes the product it ships as an update to everyone who bought. Your legal rights are not affected.

Fixes and your rights

One purchase covers one business and everyone who works for it, contractors included. Share it inside the business; do not resell it, post it publicly, or share the files or the Notion duplicate link outside it.
