Your Pistonlog subscription is managed from Workshop Settings — the Manage Workshop Subscription page shows your current plan and lets you cancel, resume, change plan, and update your payment method.
There are two pages involved. Manage Workshop Subscription is owner-only from top to bottom; anyone else opening it is told only the account owner can manage the subscription. The Billing page it links to is where the plan picker lives, and its Current Plan card shows for anyone who opens the page, so a manager can check which tier the workshop is on and when a trial ends. Only the company Owner can change anything: the plan cards, the Lifetime option, cancelling, resuming and the Stripe portal are all owner-only.
Your subscription plan
The plan you're on controls which features are available across your garage. Some features — including Inspections, Reminders, customer approvals and the Diagnostic Library — require a higher tier. A locked feature isn't hidden: its card is greyed out and unclickable, with the line "Upgrade to Pro to unlock" underneath. There's no button on it, so upgrading is something you go and do from Manage Workshop Subscription.
If your garage has no active plan at all (for example, after a subscription is cancelled), a full-screen paywall blocks the app until you choose one.
Free trial
During new-workshop setup, select Start free trial for your workshop's first monthly Essentials or Pro subscription to get 3 days free. Stripe Checkout still takes your card up front, the subscription keeps the normal price, and the first charge lands automatically when the three days are up. There's nothing to claim and no separate trial plan: cancel inside the three days and you aren't billed. Yearly plans and Lifetime don't carry a trial.
Money-back guarantee
Your first plan payment is covered by a 14-day money-back guarantee, including monthly and annual plans. The window starts when that payment is taken, after any free trial. Email ross@pistonlog.com within 14 days of the payment to request a full refund of the plan payment. No reason is required. Cancelling a subscription stops renewal; request the refund separately by email. See Terms of Service, section 5.2.
Cancelling
Cancelling takes effect at the end of the period, not immediately. On Manage Workshop Subscription, click Cancel subscription and confirm. Your plan stays fully active until the date shown on the page, which is the end of the period you've already paid for, and no further charges are made. Only on that date does the workshop drop to no plan and hit the paywall.
Changed your mind? While the cancellation is still pending, the same page shows a Resume subscription button instead. Click it before the end date and the subscription carries on as if nothing happened.
Existing Lifetime access
If your workshop already has Lifetime access, it includes the Pro features with no recurring subscription or renewal date. Manage Workshop Subscription shows "Lifetime access". There is no recurring payment to cancel. Lifetime is not part of the standard monthly or annual plan selection.
Choose or change your plan
Open Manage Workshop Subscription
Go to Workshop Settings → Manage Workshop Subscription. Your current plan is shown here.
Open the plan picker
Click Change Plan to open the Billing page with the available tiers.
Pick a plan
Click Switch to the plan you want (or Contact Us for Group) and confirm.
Billing is processed through Stripe. Choosing a plan takes you to Stripe Checkout to confirm payment, then returns you to the app.
Update your payment method
To change your card or billing details, go to Workshop Settings → Manage Workshop Subscription and click Manage in Stripe. This opens the Stripe billing portal where you can add, remove, or replace payment methods and see past invoices.
Keep your payment method up to date. If a renewal fails the subscription becomes past due, and if it's eventually cancelled a paywall blocks the app until you choose a plan again.
SMS credits
SMS credits are separate from your subscription — they're a prepaid top-up for appointment reminders, MOT and service reminders, and review requests. You'll find them on the Manage Workshop Credits page in Workshop Settings.
See SMS Credits for details on buying and tracking credit usage.
