A strong project management process

1/ Definition of your requirements

In an initial meeting, we define your needs and expectations, your terminology preferences and your processes. Together, we determine our terms for collaboration.

2/ Selection of the copywriter

We choose the copywriter whose skills best meet your requirements. The copywriter will determine with you:


  • The sources (interview, documentation)
  • The style guide and timetable


We can offer a short test for you to approve the copywriter.

3/ Proposal

We send you our proposal which confirms the schedule and the cost of the service. We will launch the project once you have approved our proposal.

4/ Writing phase

Using the sources and style guide determined with you, the copywriter produces your content in line with the proper financial end editorial practices and standards.

5/ Editing/Proofreading

The content is reread by a second copywriter who pays special attention to the client’s typographical and spelling rules. This copywriter will also validate the compliance of the text’s style and content.

6/ Client feedback

Client approves the copy in two main areas:


  • Content: consistency of the information
  • Style: compliance with the pre-defined style guide.


7/ Final adjustments and delivery

The copywriter makes the adjustments requested by the client to the style
and content before delivery.

We can also handle the layout of your documents.
