Straight answers to the billing questions Smartsheet customers actually search: refunds, the Pro plan, cancellation deadlines, and why invoices grow. Every answer below quotes Smartsheet's own public documentation, linked in the sources at the bottom of the page, and where something varies by contract, we say so instead of guessing.
No. Smartsheet's own pricing page states that "The Pro plan is only available to new customers." For teams already on Smartsheet, the other listed plans are Business, Enterprise, and Advanced Work Management; which of those your account is offered at renewal varies by contract, so confirm with your Smartsheet representative.

The Pro plan is listed for 1 to 10 Members (paid users) on Smartsheet's pricing page; the Business plan is listed from 3 Members up. Free seat types exist alongside Members on user-model plans, but note the editing rule below: a free user who edits shared items can become billable.
No, not for the unused remainder of a term: Smartsheet's cancellation documentation states that "Canceled accounts don't qualify for pro-rated refunds." Canceling stops the next renewal rather than returning money for time you have already paid for, so the standard play is to submit the cancellation on time and use the rest of the paid term to migrate calmly. Anything beyond that, such as negotiated enterprise terms, is a contract question for your representative.
The full walk-through, including what happens to your data, is in how to cancel a Smartsheet subscription →
At least 30 days: "You must submit your cancellation request at least 30 days before the renewal of your current term," per Smartsheet's cancellation documentation. Enterprise plans have no self-serve cancel button; those cancellations go through your sales representative or Smartsheet's Account and Billing team, so build in extra lead time on top of the 30 days.

It becomes read-only, then it is deleted: "Your sheets become read-only for 30 days when your subscription expires. After 30 days, Smartsheet deletes those files," per Smartsheet's cancellation documentation. The read-only window still allows exports, and Smartsheet notes that re-subscribing before removal can recover sheets from Deleted Items, but after the window there is no documented recovery path. Export everything, and verify the files, before you cancel.

Usually because free collaborators who edited items were converted into paid seats. Under the User Subscription Model, a free user who edits a shared item becomes a provisional member, and at the true-up review (quarterly on annual plans, or monthly) provisional members are auto-billed as paid seats unless an admin downgrades them first, per Smartsheet's administrator documentation. Legacy plans are converted to this model, typically at renewal, which is why the increase tends to arrive with the renewal quote.

Yes, when they edit. Smartsheet's seat-type documentation says a free user who edits a shared item receives "full Member access at no cost until the billing cycle ends, after which they either downgrade to free tiers or auto-upgrade based on admin settings." Comment-only users are on safer ground: the Contributor seat provides "free commenting and the ability to include attachments on all user model plans at no additional cost," but Contributors "cannot create items or edit content," so a single edit is what starts the escalator.
Upgrades, yes: Smartsheet's pricing FAQ says "You always have the option to upgrade your plan" and that "You can also add or remove users, purchase more licenses, or cancel your subscription at any time." What the public pages do not document is a self-serve mid-term downgrade path; whether you can reduce your commitment before renewal varies by contract, so check your agreement or ask your representative. If you are leaving entirely, remember the 30-day cancellation deadline above.
Wisegrid is one flat plan at $19 per editor per month with every feature included, view-only collaborators are always free, and nobody is auto-converted into a paid seat, so there is no true-up review to babysit, no provisional members, and no plan matrix to decode. The price is published on the pricing page and a 7-day free trial (no credit card required) lets you try it before any invoice exists. If you're weighing a move, the self-serve importer brings your Smartsheet sheets, formulas, and attachments over with you.
