The verdict in three sentences
Maintaining a franchise network's WordPress multisite costs 150 to 900 EUR per month in France in 2026, and 300 to 1,500 USD per month for English-speaking networks, depending on the number of subsites and the commitment level. The real risk is not the monthly invoice but a badly updated plugin that takes all 40 locations offline at once. Require a 4 business-hour SLA, weekly updates tested on staging and daily off-site backups, otherwise your contract does not really protect you.
Why a franchise multisite is more fragile than a regular website
A multisite shares one installation, one codebase and one set of plugins across every subsite. That is what makes it cost-effective for a network of 20 to 80 franchisees: one theme, one brand guideline, local pages rolled out city by city. It is also what makes it fragile: an incompatible update does not break one site, it breaks the whole network.
Real estate, home services and quick-service restaurant networks add one more constraint: franchisees edit their own local pages. Without restricted roles and revision history, support spends its time fixing broken content.
| Risk | Frequency (2026 estimate) | Network impact | Safeguard to require in the contract |
|---|---|---|---|
| Plugin incompatibility after an update | 2 to 4 times a year | Every subsite throws errors | Staging and testing before deployment |
| Critical plugin vulnerability | 1 to 3 alerts a month across the ecosystem | Spam injected into local pages | Monitoring and patch within 24 to 48 h |
| Bloated database | From 40 subsites | Slow admin, pages over 3 s | Quarterly table optimization |
| Expired SSL on a mapped domain | 1 to 2 times a year | Browser warning on one franchisee | Monitored auto-renewal |
| Franchisee breaks their page | Monthly | Empty or distorted local page | Limited roles and revision restore |
| Unusable backup | Rare but fatal | Loss of content and form entries | Quarterly restore test |
2026 monthly prices on the market
Contracts observed for franchise multisites fall into four tiers. The gaps mostly come from the guaranteed response time and whether a staging environment exists. French figures are in EUR excluding VAT; US, UK and Canadian agency retainers typically run 300 to 1,500 USD per month for the same scope.
| Contract tier (market) | France, per month | English-speaking markets, per month | Response time | Updates | Backups | Suitable network |
|---|---|---|---|---|---|---|
| Basic freelancer | 150 to 250 EUR | 300 to 450 USD | 48 business hours | Monthly | Daily on the server | Under 20 subsites |
| Standard agency | 300 to 500 EUR | 500 to 800 USD | 8 business hours | Weekly | Daily off-site | 20 to 40 subsites |
| Advanced | 500 to 900 EUR | 800 to 1,500 USD | 4 business hours | Weekly with staging | Off-site, 30-day retention | 40 to 80 subsites |
| Full managed service | 900 EUR and up | 1,500 USD and up | 2 h, on-call | Continuous | Hourly | National networks |
| Included change hours | 2 to 6 h a month | 2 to 8 h a month | Per contract | New pages, templates | Not applicable | All tiers |
Watch out: a cheap contract promising an SLA without specifying business hours, reporting channel and penalty commits to almost nothing. Also ask who holds the admin access and the hosting: if the relationship ends, the network must be able to recover its multisite within 48 h.
Kolonell maintenance plans
Kolonell offers three maintenance plans, separate from the market prices above: Basic 35,000 FCFA per month (about 50 EUR), Standard 75,000 FCFA per month (about 110 EUR) and Premium 120,000 FCFA per month (about 180 EUR). For a multisite, the plan is chosen based on the number of subsites, the desired update frequency and the expected response time, all written into the quote.
| Kolonell plan | Monthly price | EUR equivalent | Typical use |
|---|---|---|---|
| Basic | 35,000 FCFA | 50 EUR | Small network, few changes |
| Standard | 75,000 FCFA | 110 EUR | Growing network, regular updates |
| Premium | 120,000 FCFA | 180 EUR | Large network, priority response |
If the multisite is too degraded to stabilize, a rebuild can pay off better: Kolonell websites range from 800,000 to 3,500,000 FCFA (1,220 to 5,340 EUR) depending on the Starter, Growth or Premium tier.

Julie, marketing manager of a 45-office franchised real estate network based in Nice (illustrative persona), pays 200 EUR per month for a basic contract. The network receives about 180 contact requests a month through its local pages, or 6 a day. Last year, two network-wide outages of 2 days each cost about 24 requests. At an estimated average value of 300 EUR per request, the loss reaches 7,200 EUR.
Moving to an advanced contract at 650 EUR per month costs 450 EUR more per month, or 5,400 EUR a year. If staging prevents those two outages, the net gain is about 1,800 EUR in year one, not counting the time Julie spends managing the crisis with 45 unhappy franchisees.
FAQ
How much does WordPress multisite maintenance cost in 2026?
In France, expect 150 to 900 EUR per month depending on subsites and SLA; English-speaking agencies usually charge 300 to 1,500 USD. Beyond 80 subsites or with on-call support, managed services exceed 900 EUR or 1,500 USD per month.
Do we really need staging for a multisite?
Yes, from 20 subsites: a single incompatible plugin hits the whole network. Staging usually adds 50 to 150 EUR a month to the contract, far less than one day of downtime.
What should a maintenance SLA include?
A quantified response time (for example 4 business hours), a reporting channel, a definition of a critical incident and a penalty or credit. Without these four points, the SLA is only a statement.
Can franchisees edit their page safely?
Yes, with limited roles (editor on their own subsite only) and revision history enabled. Plan 1 to 2 hours of training per wave of new franchisees.
What backup frequency should we target?
Daily off-site with at least 30 days of retention, plus a restore test every quarter. A backup that has never been tested is not a backup.
