Gravity Forms vs Fluent Forms vs WS Form: Cost Per Client Site
If you build one website a year, form plugin pricing is a rounding error. If you look after 25 client sites, it is a line item you pay for every January, forever.
This is not a feature shoot-out. Plenty of those already exist. This is the money. What each licence tier actually costs, what happens at renewal, which integrations are locked behind the top plan, and what the true cost per client site works out to once your portfolio grows past a handful of builds.
Every price below is the published list price at the time of writing, taken from each vendor’s own pricing page. Vendors move prices, so check before you buy.
The quick verdict
- Under 5 sites: Fluent Forms is the cheapest way in, and its free version may cover you entirely.
- 5 to 25 sites: the three unlimited-site tiers sit within about $50 a year of each other. Choose on features, not price.
- 25+ sites, and you plan to stay: the Fluent Forms lifetime unlimited licence is the only option here that ever stops charging you.
- You want the deepest third-party ecosystem and will pay for it every year: Gravity Forms Elite.
- You want developer-grade control at a renewal price the vendor prints on the page: WS Form Agency.
Read on for the maths, and for the parts of each plan that will annoy you.
What each licence actually costs
| Plugin | Entry tier | Mid tier | Unlimited sites |
|---|---|---|---|
| Gravity Forms | Basic, $59/yr, 1 site | Pro, $159/yr, 3 sites | Elite, $259/yr |
| Fluent Forms | Single, $55/yr, 1 site | Agency, $111/yr, 5 sites | Unlimited, $209/yr |
| WS Form PRO | Personal, $59/yr, 1 site | Freelance, $149/yr, 5 sites | Agency, $249/yr |
Three things jump out of that table.
First, the entry tiers are almost identical. Around $55 to $59 for a single site is simply what a premium WordPress form plugin costs now.
Second, Gravity Forms gives you the least room in the middle. Its Pro tier covers three sites, while the other two cover five for a similar price. The Gravity Forms pricing page is clear that unlimited sites and the full add-on library only arrive at Elite.
Third, the unlimited tiers are closer together than the marketing suggests. $209, $249 and $259 a year is a $50 spread. On a 25-site portfolio that is two dollars per site per year. It should not decide anything on its own.
Fluent Forms is the outlier because it also sells one-off licences. Its pricing page lists lifetime plans at $279 for a single site, $479 for five sites and $719 for unlimited sites. Note that its annual figures are promotional prices against a higher list price of $79, $159 and $299, so confirm the renewal rate at checkout rather than assuming the first-year figure holds.
WS Form is the only one of the three that prints its renewal price beside its first-year price. The WS Form pricing page shows the Agency plan at $249 a year renewing at $249 a year. That is a small thing, but when you are budgeting three years out for a portfolio, a published renewal number is worth something.
The number that matters: cost per client site
Licence price is vanity. Cost per site is the figure you can actually put next to a retainer.
Here is the cheapest qualifying licence at each portfolio size, with the per-site cost in brackets.
| Sites | Gravity Forms | Fluent Forms | WS Form |
|---|---|---|---|
| 1 | Basic, $59 ($59.00) | Single, $55 ($55.00) | Personal, $59 ($59.00) |
| 5 | Elite, $259 ($51.80) | Agency, $111 ($22.20) | Freelance, $149 ($29.80) |
| 10 | Elite, $259 ($25.90) | Unlimited, $209 ($20.90) | Agency, $249 ($24.90) |
| 25 | Elite, $259 ($10.36) | Unlimited, $209 ($8.36) | Agency, $249 ($9.96) |
| 50 | Elite, $259 ($5.18) | Unlimited, $209 ($4.18) | Agency, $249 ($4.98) |
The five-site row is where Gravity Forms takes a real beating. Because Pro stops at three sites, a freelancer with five clients has to jump straight to Elite and pay roughly $52 per site. Fluent Forms covers the same five sites for $22.20 each.
Then the curve flattens. Past about ten sites every option is an unlimited licence, so the annual cost stops moving and the per-site cost simply falls as you add clients. At 25 sites all three land between $8 and $11 per site per year. At 50 sites they are all under a fiver.
That is the honest headline. Beyond roughly ten client sites, none of these plugins is expensive, and the price difference between them stops being a business decision. What matters after that point is renewals.
Renewals are where the money actually goes
A single year tells you almost nothing. Run the same portfolio out to five years at 25 sites and the picture changes shape.
| Option | 5-year total | Per site, per year |
|---|---|---|
| Gravity Forms Elite | $1,295 | $10.36 |
| WS Form Agency | $1,245 | $9.96 |
| Fluent Forms Unlimited, annual | $1,045 to $1,405 | $8.36 to $11.24 |
| Fluent Forms Unlimited, lifetime | $719 | $5.75 and falling |
The Fluent Forms annual range reflects the promotional first-year price. If your renewal holds at $209 you pay $1,045. If it reverts to the $299 list price you pay $1,405, which makes it the most expensive of the three.
The lifetime licence is the interesting one. At $719 it breaks even against Gravity Forms Elite partway through year three, since three years of Elite is $777. After that it is free, and the per-site cost keeps dropping every time you add a client.
There is a catch, and it is a real one. A lifetime licence is only as good as the company behind it. You are betting that the vendor stays in business, keeps shipping, and honours the terms. That bet has gone badly for WordPress agencies before. If you would rather not take it, an annual licence is a defensible choice even though it costs more. The same trade-off shows up across the whole stack, and it is worth thinking through properly when you decide how to price and licence the WordPress tools you resell.
It is also worth knowing what happens if you simply stop paying. Gravity Forms documents this plainly: the plugin and its add-ons stay on the site and keep working, but you lose updates, security fixes, support, downloads, and the ability to register the key on a new site. Their licence expiry documentation also warns they cannot guarantee the installation keeps working indefinitely as WordPress moves on. Treat an expired licence as a slow leak, not a saving.
The lifetime licence question
Agencies that manage a large portfolio tend to end up with the same instinct: pay once, use everywhere, stop thinking about it. It is the same logic that makes a one-payment builder licence attractive, and it is why the Oxygen Builder lifetime and agency pricing comparison works out the way it does for shops running dozens of sites.
Forms follow the same pattern with one difference: only Fluent Forms offers it. Gravity Forms has no lifetime option and no plans to introduce one. WS Form does not sell one either. If a permanent licence is a hard requirement, your shortlist has one name on it.
Be careful where you buy, too. Search for a lifetime deal on any of these and you will find resellers advertising the Agency bundle for $40. Those are redistributed copies, not vendor licences. You get no support, no reliable update channel, and you are shipping unverified code to client sites. Buy direct.
Hidden costs the pricing page does not show
Gated integrations
The sticker price is not the whole cost if the integration you need lives on a higher tier.
Gravity Forms tiers its add-ons hard. Basic gets mail and marketing connectors. Pro adds payments, Zapier and CRM integrations. Elite unlocks everything, including user registration, surveys, quizzes, signatures, partial entries and Salesforce. If a single client needs one Elite-only add-on, you are on Elite.
WS Form works the same way but counts them out: Personal includes the core builder, Freelance adds 20 premium integrations, Agency adds 58. There are no separate add-on purchases, which makes budgeting simpler.
Fluent Forms takes the opposite approach. Every paid tier includes every feature, and the only difference between plans is how many domains you can activate. For a shop that hates surprises, that is genuinely valuable.
Front-end weight
Form plugins are not free at runtime. Some load scripts and styles on pages that contain no form at all, which quietly costs you Core Web Vitals across an entire portfolio.
Be honest about what tuning can fix here. Caching and asset optimisation help — a tool like WP Rocket will defer and combine what a form plugin dumps into the head, and that is worth doing across a managed portfolio. But it does not delete a heavy dependency, it only moves it. If page weight is a hard constraint on your builds, test each plugin on a real page before you commit, and pair the result with the rest of your WordPress performance toolkit.
Licence admin across a portfolio
Nobody prices this and everyone pays it. Twenty-five sites means 25 key activations, 25 sites to check when a renewal lapses, and a support process for whoever inherits the site if a client leaves.
An unlimited licence with one key is dramatically less work than a stack of three-site licences. That admin saving is usually worth more than the $50 a year separating these plans, and it compounds in exactly the same way the rest of your operations do as you scale a WordPress agency past a handful of client sites.
Builder compatibility
If you build in a page builder rather than the block editor, check the integration before you buy. All three ship builder support, but the depth varies, and a form that needs custom styling on every site is a recurring cost disguised as a one-off. This is the same due diligence you would apply to any other integration in your builder stack.
Best for X: the clear calls
Best for lowest total cost: Fluent Forms
At every portfolio size, Fluent Forms is either the cheapest or within a few dollars of it. It also has a free version on the WordPress plugin repository with over 700,000 active installs that includes the drag-and-drop builder, conditional logic, email notifications and spam protection. For simple contact and quote forms, you may never need to buy anything.
The lifetime unlimited licence at $719 is the strongest pure-economics play in this comparison for anyone confident they will still be running 25+ sites in three years.
Buy it if cost control is the priority and you can live with a slightly thinner third-party ecosystem.
Best for ecosystem depth: Gravity Forms Elite
Gravity Forms is the oldest of the three and has by far the largest network of third-party developers building on top of it. If a client’s obscure CRM has a WordPress form connector, odds are it was written for Gravity Forms first.
Elite at $259 a year for unlimited sites and every add-on is not bad value at scale. It is $10.36 per site at 25 sites. You are paying a small premium for the safest bet on compatibility.
Buy it if you inherit sites, integrate with unusual third-party systems, or want the option nobody ever gets fired for choosing.
Best for developer control: WS Form PRO Agency
WS Form is the most technically capable form builder of the three and the least known. Sixty-five field types, calculated fields, repeatable sections, data encryption and conditional logic that goes well past show-and-hide. The free LITE version is available if you want to try the interface first.
Its Agency plan at $249 a year is the middle price with a published, flat renewal.
Buy it if you build complex forms — multi-step applications, calculators, conditional quoting — and the extra capability saves you custom development time.
Where each one will annoy you
No plugin here is flawless, and pretending otherwise helps nobody.
Gravity Forms has no free version and no lifetime licence, so you pay every year with no exit. The three-site Pro tier is stingy and forces small shops onto Elite earlier than they should have to. The interface, while much improved, still feels older than its rivals.
Fluent Forms has a smaller third-party developer ecosystem, so a niche integration is more likely to be missing. Its promotional pricing makes true renewal cost harder to pin down than it should be. And the lifetime licence carries vendor risk that a subscription does not.
WS Form has the smallest community of the three, at around 10,000 active installs of the free version compared with Fluent Forms’ 700,000-plus. That means fewer tutorials, fewer Stack Overflow answers and fewer freelancers who already know it. The power that makes it excellent also gives it the steepest learning curve, and there is no lifetime option to offset the annual cost.
Final recommendation
For most agencies running 25 or more client sites, Fluent Forms Unlimited is the correct default, and the lifetime licence is the correct version of it if you are confident about the next three years. It is the cheapest per site at every scale, every feature is included at every paid tier, and the free version handles the simple builds so you are not burning licence slots on brochure sites.
Choose Gravity Forms Elite instead if compatibility is worth more to you than $50 a year. On a portfolio with unpredictable client integrations, that is a rational trade.
Choose WS Form Agency if your work is genuinely form-heavy — calculators, multi-step applications, conditional pricing — because the development time it saves will dwarf the licence cost within one project.
What you should not do is stay on a stack of single-site licences past your fifth client. That is the only genuinely expensive option on this page, and it is the one most freelancers drift into by accident. The same principle applies right across the plugin stack a freelance designer runs: buy for the portfolio you have, not the one you had three years ago.
The same one-payment, unlimited-sites logic that makes a form licence work at scale is exactly why agency-tier builder licences like Oxygen Builder hold up so well on a large portfolio. Get the licensing model right once and it pays you back on every site you launch after it.
Frequently Asked Questions
Which WordPress form plugin is cheapest for an agency with 25 client sites?
Fluent Forms. Its Unlimited annual licence at $209 works out to $8.36 per site per year at 25 sites, against $9.96 for WS Form Agency ($249) and $10.36 for Gravity Forms Elite ($259). The Fluent Forms lifetime unlimited licence at $719 is cheaper still over any period longer than about three years, because it never renews.
Does Gravity Forms have a lifetime licence?
No. Gravity Forms sells annual subscriptions only: Basic at $59 for one site, Pro at $159 for three sites, and Elite at $259 for unlimited sites. There is no one-off purchase option, so Elite is a permanent $259 a year line item. Of the three plugins compared here, only Fluent Forms offers a lifetime licence.
What happens when a form plugin licence expires?
The plugin keeps working. Gravity Forms documents that the plugin and its add-ons remain installed and continue to operate, but you lose software updates including security fixes, technical support, the ability to download files, and the ability to register the key on a new site. The vendor also warns it cannot guarantee an unlicensed installation will keep working indefinitely as WordPress changes around it.
Is the Fluent Forms lifetime licence worth it for an agency?
Financially, yes, if you expect to still be running a portfolio in three years. At $719 for unlimited sites it breaks even against Gravity Forms Elite partway through year three, and costs nothing after that. The risk is vendor risk: a lifetime licence is only as good as the company honouring it. If that worries you, an annual licence is a defensible choice even though it costs more over five years.
Can one unlimited licence be used across all my client sites?
Yes. Gravity Forms Elite, Fluent Forms Unlimited and WS Form PRO Agency all permit activation on an unlimited number of domains under a single key. That is the point of the tier, and it is also where the real saving is: one key across a portfolio is far less admin than tracking a stack of one-site and three-site licences.
Do I need the top tier just to get the integrations I want?
With Gravity Forms and WS Form, often yes. Gravity Forms gates payments and CRM connectors behind Pro, and everything else behind Elite. WS Form includes 20 premium integrations at Freelance and 58 at Agency. Fluent Forms is the exception: every paid tier includes every feature, and the only difference between plans is how many domains you can activate.
At how many sites should a freelancer move to an unlimited licence?
Around five clients. With Gravity Forms the jump is forced early because Pro covers only three sites, so a fifth client pushes you to Elite. With Fluent Forms and WS Form the five-site mid tiers hold a little longer, but by roughly ten sites the unlimited plan is cheaper than stacking mid-tier licences on all three products.
Working out the licence maths for a whole portfolio rather than a single site? Run the same exercise across your builder, hosting and performance stack before your next renewal date – the savings compound far faster than any single plugin decision. Start with the plugin and licensing guides on the blog, then price your stack for the portfolio you actually run today.
