Method and limits, stated up front

This comparison is assembled from two sources and no others: this publication’s approved review of Trello and its approved review of Smartsheet. Each of those reviews was built entirely from the vendor’s own published pages, retrieved on 2026-11-06, and in each case no product was signed up for, installed or used. Nothing below speaks to speed, usability, reliability, interface quality or the quality of any AI output, because nothing below rests on using either tool. Where one review settles a point and the other does not, that is said rather than filled in. Where a vendor does not publish something, that is reported as a finding about buying from them.

There is no winner here, no score and no ranking. The useful output of a comparison like this is a map of which decisions the published material can answer and which it cannot.

The scenario held fixed

One team of ten people doing client project work, read against both products throughout, so tiers and published limits stay like for like.

One thing has to be said immediately, because it governs the whole pricing section. Ten people on the team does not mean ten paid licences on either side, and the two vendors do not count the same way. Trello prices per user and its own FAQ says a Workspace member, “either as a normal member or as a team admin - is considered a billable team member” (trello.com/pricing, retrieved 2026-11-06). Smartsheet prices per Member and advertises unlimited free Contributors (smartsheet.com/pricing, retrieved 2026-11-06). The two numbers are not the same unit and are never treated as such below.

What each vendor says the product is

Trello’s home page frames the product around three primitives under a heading it calls “Trello 101”: “Stay organized and efficient with Inbox, Boards, and Planner” (trello.com/, retrieved 2026-11-06). Smartsheet’s home page frames itself as “The Execution Hub for Enterprise Work” with the line “Where people and AI get work done, together” (smartsheet.com, retrieved 2026-11-06), over what its pricing table shows to be a sheet based working surface with views, formulas, forms, dashboards and automations layered on top.

One deployment question is settled on one side only. Trello’s own FAQ answers it directly: “Trello is proudly a cloud-only product. We offer access via the web, desktop, and our awesome mobile apps” (trello.com/pricing, retrieved 2026-11-06). The Smartsheet review does not address deployment or self-hosting at all, so for a team with an on-premises or data-residency mandate, Trello is answered and Smartsheet is simply not covered by the material here. That is not a point in anyone’s favour; it is a gap a reader with that requirement has to close elsewhere.

Setup: what a team must decide and build first

This dimension can only be half compared, and the reason is worth knowing before you read further.

On the Smartsheet side, the shape of setup is documentable from the plan table. Grid, Gantt, calendar, table and board views are listed as available on all four plans, with timeline view the one view withheld from the entry tier, marked unavailable on Pro and available on Business and above. Column types, cell formulas, column formulas, cross sheet formulas, dependencies, filters, conditional formatting, cell linking, column links and row and column locking are all marked available on Pro and above (smartsheet.com/pricing, retrieved 2026-11-06). A team adopting Smartsheet is therefore deciding sheet structure, column types and dependency relationships up front, with formula and dependency mechanics present from the entry tier.

On the Trello side, the equivalent is not established. The Trello review records that none of the pages consulted explains how cards, lists and boards relate structurally, what a card can hold, or how work moves between lists; the home page says only “sign-up, create a board, and you’re off!” (trello.com/, retrieved 2026-11-06). So the Trello half of this comparison is not available from the published pages, and this article does not infer it. A reader who needs to know whether Trello can express their workflow needs the product documentation, which was not consulted for either review.

One structural addition on the Trello side is documented. Custom Fields arrives at Standard and is described as a way to “bring process and formality to your workflow by structuring information on Trello cards” (trello.com/pricing, retrieved 2026-11-06), alongside advanced checklists and card mirroring. That tells you where process formality begins on the plan ladder, but not how the underlying model works.

Seats for ten people, which is ten licences on neither side

Trello’s rule is published and strict. Every Workspace member including team admins is billable, and “Any Guest that is on more than one board within the Workspace is considered a Multi-Board Guest and is billed at the same rate as Standard or Premium Workspace members” (trello.com/pricing, retrieved 2026-11-06). For client project work that rule is the first thing to model: a client contact on one board is a single board guest, available from Standard, but the moment that person needs a second board they cost a full seat.

Smartsheet draws a three way distinction between Members, Contributors and Guests, with a fourth category of Provisional Members. Contributors are listed as available on all four plans and the Pro plan card describes them as “Unlimited free Contributors”; Guests are unavailable on Pro and described on the Business card as “Unlimited free Guests” (smartsheet.com/pricing, retrieved 2026-11-06).

Here is where the comparison stops, and a reader deciding between these two should finish this paragraph knowing exactly what is missing. The Smartsheet review records that none of the pages consulted defines what a Contributor, a Guest or a Provisional Member may actually do. Whether a Contributor can edit a sheet, create one, own one or only comment is not established. Because the paid Member count for a team of ten depends entirely on how many of those ten must be Members rather than Contributors, the Smartsheet paid seat count for this scenario cannot be settled from the published material, and no number is chosen here to make the comparison tidy. Trello’s billable headcount for ten people on the team is the clearer figure of the two, but only because Trello bills every member.

Both vendors put a plan edge exactly at ten

A team of exactly ten sits on the boundary of both entry tiers, which is a coincidence worth noticing.

Trello Free is published at “$0 USD” and “Free for up to 10 collaborators per Workspace” (trello.com/pricing, retrieved 2026-11-06). The Trello review flags a tension the pages do not resolve: the comparison table carries a row labelled “Unlimited Workspace collaborators” whose per-tier marks were not legible in the fetched text, so which plans that row applies to is unresolved. Smartsheet Pro’s plan card states its range as 1 to 10 Members with unlimited Contributors and Guests not included (smartsheet.com/pricing, retrieved 2026-11-06).

So on both sides, ten people is the last number that fits the entry tier as published, and on both sides an eleventh person is the event that forces a decision. On Trello, the Free tier also carries a limit of up to 10 boards per Workspace, unlimited storage with a 10MB per-file cap and 250 Workspace command runs per month. The Trello review’s judgement is that the board ceiling, not the people ceiling, is what usually ends Free, because board count grows with team habits rather than team size.

Daily work, for a team member and for whoever runs the work

For a team member, the published difference in what is on screen is real. Trello offers the board alone until Premium, which adds Calendar, Timeline, Table, Dashboard and Map views plus Workspace level Table and Calendar views (trello.com/pricing, retrieved 2026-11-06). Smartsheet lists grid, Gantt, calendar, table and board views on Pro, with timeline view from Business (smartsheet.com/pricing, retrieved 2026-11-06). Read against a team of ten on an entry or mid tier, Smartsheet publishes more ways of looking at the same work at its cheaper tier than Trello does at Standard, and Trello concentrates its views at one step on the ladder.

Automation is where the two look superficially identical and are not demonstrably comparable. Trello Free meters 250 Workspace command runs per month, rising to 1,000 at Standard and unlimited at Premium. Smartsheet Pro limits automated triggers to 250 per month, becoming unlimited at Business. Both figures come from the respective pricing pages, retrieved 2026-11-06. The catch is that the Smartsheet review records the unit of a trigger as undefined on the pages consulted: whether one workflow alerting twenty recipients consumes one trigger or twenty is not published. Two numbers that read the same are therefore not shown to be the same budget, and a reader should treat the apparent match as a coincidence of labelling until someone establishes the unit.

For whoever runs the work, both vendors put administration higher up. Trello places “admin and security features”, Observers, Collections and command run administration at Premium; the Trello review notes that what the “admin and security features” line contains is not itemised on the pages consulted. Smartsheet lists Admin Center and User Management on all four plans, with group management, account discovery, scheduled backups and domain validation starting at Business (smartsheet.com/pricing, retrieved 2026-11-06).

Reporting: what an accountable lead can see

This is the dimension where the two products diverge most clearly in published terms.

Trello gates reporting to one tier. Dashboard, described as “Trello’s reporting tool” for “real-time insights” to “communicate your team’s progress”, along with Timeline, Table and the Workspace level table and calendar views, is a Premium feature, and there is no intermediate price between Standard and Premium (trello.com/pricing, retrieved 2026-11-06). For a lead who needs a timeline or a dashboard inside the tool, the Trello answer is Premium or nothing.

Smartsheet puts unlimited dashboards, reports and sheets on every plan, but constrains them on Pro: dashboards are capped at 10 widgets each and reports are limited to one sheet per report, both becoming unlimited at Business (smartsheet.com/pricing, retrieved 2026-11-06). The Smartsheet review reads the one sheet per report limit as ruling out cross project roll up reporting on Pro. Portfolios appear only at Enterprise and above, and Work Insights is gated to Enterprise and above. For a team of ten running several client projects at once, that is the sharpest published constraint on the Smartsheet entry tier: reporting exists on Pro, but not across projects.

On getting data out, the two are not comparable. Smartsheet lists sheet export as available on all four plans. The Trello review records that the contents, formats and scope of Premium’s “simple data export” are not established by the pages consulted, so export depth cannot be set side by side. For anyone weighing lock-in or feeding an existing reporting stack, that is the unknown that bites, and it sits on the Trello side.

Pricing for the same ten people, by tier

All figures below are list prices in US dollars from the vendors’ pricing pages, both retrieved 2026-11-06.

Trello, per user per month: Free $0; Standard $5 billed annually or $6 billed monthly; Premium $10 billed annually or $12.50 billed monthly; Enterprise $17.50 billed annually, with the annual figure spelled out as “$210.00 annual price per user” (trello.com/pricing). The Trello review’s arithmetic for ten seats: $600 per year at Standard billed annually against $720 billed monthly, and $1,200 per year at Premium billed annually against $1,500 at the monthly rate.

Smartsheet, per Member per month: Pro $12 billed monthly or $9 billed yearly, card range 1 to 10 Members with unlimited Contributors; Business $24 billed monthly or $19 billed yearly, with a three Member minimum and unlimited Guests and Contributors (smartsheet.com/pricing). The Smartsheet review’s arithmetic: ten Members on Pro is $90 a month at list.

What each step buys is published on both sides. Trello Standard removes the Free plan’s two walls, giving unlimited boards, 250MB per file and 1,000 command runs, plus Custom Fields, advanced checklists and card mirroring, and no new view. Trello Premium adds the views, unlimited command runs, admin and security features, Collections, Observers and simple data export. Smartsheet Business adds Guests, timeline view, workload tracking, baselines, report grouping and summary, conditional form logic, activity log, document builder, API calls and the Power BI, Tableau and external AI tool integrations, and lifts the Pro widget, report and automation ceilings.

The comparison of the two monthly totals has to be read with the seat caveat from above still standing. $90 a month is ten Smartsheet Members at list, and the published material does not establish how many of ten people doing client work would have to be Members rather than Contributors, so that figure is a ceiling for ten Members and not a settled price for this team. Trello’s $1,200 a year at Premium, by contrast, is ten billable seats because Trello bills every member, before any multi-board guest is added.

Where each vendor stops publishing

Both pricing pages stop short of a complete budget above their entry tiers, in different ways, and that is itself a finding about buying from them.

Smartsheet shows no figure at all for its top two tiers: both display “Custom pricing” with a “Contact us” action, Enterprise annotated “10+ Members” and Advanced Work Management annotated “Solutions for your needs”. Resource Management and Brandfolder are listed as add-ons with no price, every support package is unpriced, and the four security add-ons (data retention policies, data egress, event reporting and Customer Managed Encryption Key) are marked as add-ons even at Enterprise with no figure attached. Only two add-ons carry published floors: Dynamic View “Starting at $125 /month” and Data Shuttle “Starting at $100 /month”, with the page not stating what those floors buy. And a footnote beneath the comparison table states “The Pro plan is only available to new customers” without saying what existing customers pay instead (smartsheet.com/pricing, retrieved 2026-11-06).

Trello publishes a list rate at every tier including Enterprise, which is the more complete published ladder of the two. But the Trello review records as unresolved: any Enterprise seat minimum or volume tier, the values behind the plan card’s interactive “Est. cost for users” estimator, and the size and eligibility of the non-profit and education discounts the FAQ confirms exist. The payment FAQ directs Enterprise buyers to “contact our sales team” for “more options” (trello.com/pricing, retrieved 2026-11-06).

For a team of ten the practical reading is that both public pages are usable for this scenario, since ten people lands at or below each vendor’s entry and mid tiers, where list prices exist on both sides. It is above that line that the pages stop being budgeting tools.

Currency, and what each page discloses

Smartsheet’s pricing page offers the same prices in thirteen currencies, naming AUD, CAD, CHF, DKK, EUR, GBP, JPY, NOK, NZD, SEK, SGD, USD and ZAR; in British pounds it shows Pro at £10 monthly or £7 yearly and Business at £19 monthly or £15 yearly (smartsheet.com/pricing, retrieved 2026-11-06). The Trello review records every Trello figure as marked USD, with no visible currency switch in the fetched text, and lists non-USD pricing and tax treatment as unresolved. This is a statement about what each vendor publishes, not a price comparison between the two.

Single sign on and support

Smartsheet lists single sign on, Admin Center and User Management on all four plans, with SAML based SSO starting at Enterprise (smartsheet.com/pricing, retrieved 2026-11-06). Trello routes SAML SSO through a separate Atlassian product: the pricing page’s SSO row states that “Atlassian Guard is a separate subscription that your company can enable across all your Atlassian products and starts at $4/month/user”, while the Enterprise plan blurb separately says that plan “includes Atlassian Guard Standard” (trello.com/pricing, retrieved 2026-11-06). Whether the $17.50 Enterprise figure is therefore all-in for SSO is not resolved by that page. The concrete point for a ten person team that needs SSO on Trello is that it is not looking at a single line item, and the published floor for the separate subscription is $4 per user per month.

Support cannot be compared at all. Smartsheet’s support page describes three packages, Base Support labelled “For all plan types”, the Standard Support Package labelled “Included in Enterprise Plan” and the Premium Support Package labelled “Included in Advanced Work Management. Add-on to Business & Enterprise”, and states a first response target of “Less than two hours regardless of case origin (web, phone, chat)” without attaching it to a specific package (smartsheet.com/services/support, retrieved 2026-11-06). No price appears for any package. On the Trello side, the comparison table has a Support row whose per-tier contents were not legible in the fetched page text, and only Enterprise has a stated level, described in its plan blurb as “24/7 Enterprise Admin support”. So for a team buying at Standard, Premium or Pro, what support means is documented on one side and unreadable on the other, which leaves no basis for a comparison.

The published evaluation offers

Both vendors publish a way to look before buying, and neither was used for these reviews. Trello’s guide page carries a promotional block headed “Try Premium free for 14 days” (trello.com/guide, retrieved 2026-11-06), which happens to cover exactly the tier where the views live. Smartsheet’s pricing page advertises “30 days free, no credit card required” without stating which plan’s features the trial includes (smartsheet.com/pricing, retrieved 2026-11-06). Since the Smartsheet tier boundary between Pro and Business is where timeline view, Guests, baselines and API access sit, the unstated trial tier matters: a team could evaluate on capabilities it would lose on subscribing to Pro.

Which situation each product suits

On the two reviews’ own terms, and with no winner, score or ranking:

Trello Free or Standard fits a team of ten that can work inside boards and already reports somewhere else. Free holds if the team can live within 10 boards per Workspace, a 10MB per-file cap and 250 command runs a month. Standard at $5 per user per month billed annually, $600 a year for ten seats, buys capacity and process fields, not visibility.

Trello Premium fits the case where a timeline and a dashboard have to exist inside the tool. That is $10 per user per month billed annually, $1,200 a year for ten seats, and there is no intermediate price to reach it.

Smartsheet Pro fits a team of ten or fewer paid Members that needs formulas, dependencies and Gantt from the entry tier, and whose reporting stops at one sheet per report and ten widgets per dashboard, with no external Guests. At $9 per Member per month billed yearly, ten Members is $90 a month at list.

Smartsheet Business becomes the answer rather than an upgrade the moment Guests, timeline view, baselines, workload tracking, report grouping, conditional form logic or API access is required, at $19 per Member per month billed yearly with a three Member minimum.

The open part of this decision, for a team of ten doing client project work, is the one neither vendor page closes: what a Smartsheet Contributor can actually do. Client work means outside collaborators, and on Smartsheet the entry tier has no Guests while advertising unlimited free Contributors whose permissions are undefined on the pages consulted. Until that is answered, the Smartsheet side of this comparison has no settled paid seat count and therefore no settled price for this team, and that question is worth asking before a trial, not during one.
