One application per sector: build your Odoo once, deploy it to every client

If you build Odoo for a living, you probably notice that your clients in one line of business want much the same thing. Two pharmacies need the same stock rules and the same reports. Ten fast-food restaurants want the same till and the same menu structure. The differences are a logo, a few prices and a list of users.

The way you pay for hosting should follow that shape. On Ordomatics it does.

What an application is

On Ordomatics, an application is what you build: a repository with your Odoo modules, a Dockerfile, a test environment and a live site. In the portal it is a project. It is built once and versioned in git, and it is the thing you improve over time.

A client is a business that uses your application: its own database, its own address, its own users and its own data. The same application runs for every client, and no client sees another’s data.

That suggests how to organise the work: one application per sector.

• pharma: the modules and settings every pharmacy and clinic needs
• resto: the till, the menu and the kitchen flow for restaurants
• alimentation: stock and suppliers for food shops

What it costs

49€ a month per deployment. The application with its first client is one deployment, and each additional client is another.

What you do not pay for twice is the work. The first pharmacy carries the cost of building the application; the second, third and twentieth get it as it is, and you do not repeat any of the setup.

Users are not charged. Each client’s database can have as many users as it needs. The one exception is Odoo Enterprise: if you bring in Enterprise modules, Odoo’s own licence for them applies, and that is between you and Odoo.

What adding a client involves

You open the project’s production environment in the portal, type the client’s name and a contact email, and press Onboard. About four minutes later the client has:

• their own database, with the same modules your application runs
• their own address, for example baobab.pharma.ordomatics.com
• their own users and data, separate from every other client’s

You hand over the address and they sign in. You can pause a client without touching their data, and offboard one when they leave. The step-by-step version is in Onboard a client.

One release reaches every client

This is where the model pays off. When you improve a module, you push it once. The change goes through your test environment and, when you release, reaches the clients under the application, because they all run the same image built from your repository. Auto-upgrade is on by default for each client, and you can turn it off for one that is not ready to move.

You fix a bug in the pharmacy application once, not twenty times.

How many clients can share an application

As many as you have. There is no limit on the number of clients per application, and the price per client stays the same however many you add.

Clients share the application’s servers, so what grows with them is the load, not a count. A busy client uses more than a quiet one, and a larger set of clients needs larger servers. You size the application for the load you expect and resize it as you grow.

Where it stops

Be clear about the limits before you plan around this:

• The first client you add restarts your application’s servers once, so choose a quiet moment. Later clients only restart the background jobs.
• A client is a database, not a copy of the code. If one client needs different modules from the rest, that is the sign they belong in another application.
• One application is one sector. If you serve several sectors, you need an application each. The Partner plan, at 395€ a month, covers unlimited applications on a dedicated cluster. You pay for the cluster itself.

Where to start

Create the project for your first sector with the Getting Started guide, then add your first client with Onboard a client. If you want to see the other half of the idea, read Your Odoo environment is code.
