Launch online store checklist: buy one first

Your store works for you because you already know where everything is. A first customer has no saved address, no coupon and no patience, so the checklist starts with one guest order.

What should a launch checklist for an online store cover?

Start with one guest order: a product, a cart, a shipping address in a region you do not live in, and the payment step. Check the shipping cost and tax before the payment step, the order confirmation email, and the price and variant choices on the product page. A simulated visitor follows that order from a public address and stops at the payment step, since it cannot pay with a real card, then reports where it got stuck.

What this looks like in a report

Who

Where they stopped
Checkout, after entering a shipping address

“The total looked fine until I typed my sister's address, then a line said tax would be added, with no amount. I do not want an account, so I will look elsewhere.”

The fix. Show the tax and shipping lines as soon as a shipping address is typed, with an amount or a clear estimate, and allow guest checkout on the first screen of checkout. Then reach the payment step as a guest from a private window, with an address in a region you rarely ship to, and confirm the line appears before payment.

The first customer finds the one step you never tried

A store owner orders for themselves from a logged-in account, with a saved address and a coupon that never expires. A first customer arrives as a guest, types a different city, and sees a shipping line that says not available, or a tax line that only appears after the payment step. Some stores still have payments set to test mode, so a real order never completes. The owner has seen the success page many times, so it does not look like a problem from their side. A launch check has to start from zero, the way a stranger does.

  • Guest checkout: can a visitor with no account reach payment without signing up?
  • Shipping: does a distant address return a rate, rather than a blank line?
  • Tax and fees: do they appear before the payment step, not after it?
  • Payment settings: is the provider in live mode, and tested once in its own test mode?
  • Confirmation: does the order email arrive, and does its link open the right order?

The guest path is the one most stores never walk

Sign out, open the store in a private window and add one item without an account. Look for the moment checkout asks you to create an account before payment, and whether a guest option is labeled clearly. A store that only works when logged in loses every first customer who does not want an account yet. The same walk shows whether a coupon field, a gift note or a required phone number stops the guest. Write down each field that appears, since your saved account has hidden them all.

Shipping and tax have to show before the payment step

Type an address in a region you never ship to, and see whether checkout says so before the payment step, or only after the card is entered. Then type an address in a region you do ship to, and compare the shipping line with the rate you set. A free shipping threshold shown in the cart but missing at checkout is a mismatch worth looking for. The run types the address and stops at payment, so it can show whether the shipping and tax lines appear in time. It cannot judge whether your tax settings are right for each place you sell.

The confirmation is what a first customer checks next

A first customer checks their inbox before they trust the store. Check the confirmation with a real order you place yourself, then confirm the email arrives, names the right items and total, and links to an order page that loads. Check the sender name as well, since an unfamiliar name in a spam folder reads as a scam. The simulated run stops at payment and never sends an order, so it cannot check this step.

What you get with Mimiq

  1. 01

    Run it by hand, or on every pull request

    Paste a link and a task in the app and watch the visitors work. Or run them on every preview deploy: the GitHub Action comments on the pull request, any other CI can call the MCP endpoint, and your coding agent can run it too.

  2. 02

    Bugs and usability problems in one report

    The browser records errors and failed or slow requests on the step they happened. The visitors say where the wording or the steps confused them, and where they left.

  3. 03

    Visitors that behave like your audience

    Each visitor is a different profile with a reason to be there, matched to who the page is for, described by you, or built from your own customers.

  4. 04

    A prompt to fix each problem

    Every problem comes with a fix to paste into Cursor, Claude Code, Lovable or any coding agent, and one prompt hands over the top problems at once. Then send the same visitors through again.

  5. 05

    Follow every visitor

    See each visitor's whole path, step by step with screenshots, and what it was thinking at every step. Ask any visitor a question.

The browser records relevant JavaScript errors and failed or slow app requests encountered during the run, attached to the step where they occurred. The visitors are simulated: they find problems, they do not predict how many real people will convert.

A new shipping zone or theme update can stop the first guest at payment

Stores change after launch: a new shipping zone, a discount rule, a theme update or a payment app. Each one can block a guest at the payment step while your own logged-in order still works. Run one guest order again after each change, from a private window, before you send the store any new traffic.

Questions

Should I place a real order before launch?

Yes, once, with your own card from a private window that holds no saved details, and refund it afterward. A simulated visitor cannot pay with a real card, so your own order is the only check of the live payment. Use the payment provider's test mode for the rest of the testing.

How far from my own address should the simulated shipping address be?

Far enough that the rate is not the one you saved. Pick a region you do not ship to and one you do, and see whether checkout says which before the payment step. A rate that appears only at the card screen is the fault to fix.

Does the test check my tax settings?

It shows whether a tax or fee line appears, and where, for the address it typed. It does not check whether your tax setup is right for each place you sell, and it is not tax advice. Check those rules with your accountant or your payment provider's own documentation.

Will a simulated order show whether the store will sell?

No. It does not predict orders, conversion or revenue from the store. It shows whether a first guest can reach the payment step and understand the price, the shipping and the total. Sales come from your store's reports once real customers buy.
