Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Gumroad

  • The fee is a flat percentage of every sale with no monthly plan to cap it, so a product that succeeds pays proportionally more forever, and past a certain monthly revenue a self-hosted cart plus a payment processor costs a fraction of it.
  • Sales that come through the Discover marketplace carry a substantially higher cut, so marketplace-sourced revenue is materially less profitable than direct revenue and the two need tracking separately to know what the channel is really worth.
  • The storefront is a Gumroad-hosted page with limited layout and branding control, so the customer experience is recognisably Gumroad's rather than yours, and there is no template language to extend it.
  • Stored payment methods cannot be transferred to another platform, so migrating an active membership requires every subscriber to re-enter their card, and the churn that causes is the real exit cost rather than any contract term.
  • Acting as merchant of record means Gumroad, not you, is the party in the customer's bank statement and in the tax records, which simplifies compliance but weakens the direct customer relationship and limits what you can do with the transaction data.

Inventory Lab

  • InventoryLab is no longer sold standalone and is now bundled into Three Colts' Seller 365 plans starting at $69 per month for a single user, rising to $199 per month for the Pro tier
  • Multichannel listing requires the separate UniCon add-on, priced from $49 to $449 per month depending on tier

Answered from the vendors’ own pages

Gumroad: How does Gumroad charge?

A flat percentage of each sale rather than a monthly subscription, with a higher rate on sales it sources through Discover. Check the current pricing page for whether payment processing is included in or added to that percentage.

Inventory Lab: What is the free trial period for Inventory Lab?

Inventory Lab offers a 14-day free trial, with bonus days awarded when connecting Amazon accounts.

Source
Gumroad: When does it stop making financial sense?

When your monthly revenue times the percentage exceeds what a hosted cart subscription plus standard processing would cost. That crossover arrives earlier than most sellers expect.

Inventory Lab: Can I save money on Inventory Lab with annual billing?

Yes, annual billing saves money: Standard saves $48/year, Teams saves $120/year, and Pro saves $192/year compared to monthly billing.

Source
Gumroad: Does it handle VAT on digital goods?

Yes. It acts as merchant of record and takes on calculating and remitting VAT and sales tax on digital sales, which is the main reason solo creators selling internationally choose it.

Inventory Lab: Is there an add-on to use Inventory Lab on channels beyond Amazon?

Yes, the UniCon multichannel add-on is available starting at $49/month for expanding beyond Amazon.

Source
Gumroad: Can I move my subscribers elsewhere later?

You can export customer records, but not stored payment methods. Every active subscriber has to re-enter a card on the new platform, and some will not.

Gumroad: Can I sell physical products?

It is built for digital goods. Inventory, shipping and fulfilment are not what it is designed around, so a physical catalogue belongs on a store platform.
