One licence for fifty sites costs less than most plugins charge for five.
Document plugins are priced by site count, and the step from one site to five, or five to fifty, is where an agency’s bill is decided. This guide prices the five-site and fifty-site plans of six vendors over three years and works the figures back to a cost per site per year.

The short answer
Per site, the price falls fastest at fifty
A fifty-site document plugin licence costs between $179 and $599 a year at published prices, and a five-site licence between $69 and $349. FileDeck Pro is $99 for up to five sites and $179 for up to fifty, so an agency running twenty client libraries pays $8.95 per site per year, and one running fifty pays $3.58.
The vendors with the lowest single-site prices are not necessarily the lowest at scale. FileBird’s add-on, cheapest for one site at $39, is $199 for unlimited sites; Filr goes from $49 to $299. Download Monitor sells no plan above five sites. The tables below show each vendor’s cheapest plan that covers the site count.

Cost per site per year
The annual price divided by the sites the plan covers, with every site in use. A plan you only half fill costs twice this per site.

|---|---|---|---|
| FileDeck Pro, 5 sites | $99 | 5 | $19.80 |
| FileDeck Pro, 50 sites | $179 | 50 | $3.58 |
| Document Library Pro Essentials, 5 sites | $249 | 5 | $49.80 |
| Document Library Pro Essentials, 50 sites | $399 | 50 | $7.98 |
| Document Library Pro Advanced, 50 sites | $599 | 50 | $11.98 |

What counts as a site
A FileDeck Pro licence covers up to 1, 5 or 50 activated WordPress sites, and a site uses one activation when the plugin is activated and connected on it. Activations are managed from the plugin’s Account screen on each site, so a client site that leaves can be deactivated and the activation reused on the next one. Each plan size is the cap on simultaneous activations, not a quota of sites you can ever use.
Other vendors count sites in their own ways, and some treat a staging copy differently from a live site. Their pricing pages, linked at the foot of this page, are the authority on that; this guide does not describe their rules.
For agencies there is one more figure to hold onto: the fifty-site plan is $179 a year whether twenty or fifty sites are live, so adding a client library to an existing licence adds no licence cost until the fifty-first. The agency page covers how client libraries are set up and handed over.
Questions about multi-site licences
How much does a document library plugin cost for an agency with many client sites?
At published prices on 13 October 2026, a fifty-site document plugin licence costs between $179 and $599 a year. FileDeck Pro is $179 for up to fifty sites, Document Library Pro is $399 for Essentials or $599 for Advanced, WordPress Download Manager Developer is $499 for up to 48, FileBird’s unlimited add-on is $199 and Filr’s unlimited plan is $299. Download Monitor sells no plan above five sites.
Does the FileDeck 50-site plan cover unlimited sites?
No. It covers up to fifty activated sites at once. If you need more than fifty, buy a second licence; FileDeck does not sell an unlimited-site plan.
Can I move a licence from one site to another?
Yes. Deactivate the licence on the site that no longer needs it from the plugin’s Account screen, and the activation becomes free for another site. The licence itself is tied to your account, not to a domain.
Do I need the 5-site plan for one live site plus a staging copy?
A staging or local development copy is a second activation, so to keep both connected at once you would need the five-site plan. Many agencies instead develop on a staging copy with the free version and activate Pro on the live site at launch; the free library works the same on both.
Is the AI tier priced per site the same way?
Yes. The AI tier is $119 a year for one site, $199 for up to five and $399 for up to fifty, renewing at the same price. It includes everything in Pro, and AI usage is billed by your own AI provider, not by FileDeck.
Fifty client libraries. One $179 licence.
