Evolink: one Odoo platform for an IT and telecom company, live across four Swiss sites in three months.
Evolink replaced separate tools for quoting, projects, timesheets and invoicing with one Odoo platform in three months, and stopped losing billable work between systems.

Why a growing Swiss IT and telecom company outgrew its separate tools.
By 2024 Evolink SA, a managed IT and telecom provider for small and mid-sized companies across French-speaking Switzerland, had grown to around forty people working out of four sites: Daillens, Rossens, Sion and Carouge. For Yves Contat, the company's CEO, the way Evolink ran itself was no longer keeping up with that growth. The work was unusually varied for a firm its size, client billing and supplier billing, subscriptions, project delivery, timesheets, and each strand sat in its own tool. A choice was approaching: keep stitching tools together, or move the whole company onto one system.
The challenge
Re-entered hours, scattered quotes and unbilled work across disconnected tools.
The hours, in two places at once
A technician would log time in one program while the job it belonged to lived in another, so people re-keyed the same entry by hand and the numbers rarely lined up. The friction was the copy-paste between modules, not the clients themselves.
Quotes on the left, hours on the right
With offers in one place and time and invoicing in others, putting a single client picture together meant opening several systems and hoping they agreed. The risk of error was high and there was no central view.
Work that quietly never got billed
Because the strands lived apart, things slipped through, a line forgotten here, a job not invoiced there, and nobody could see the leak while it was happening.
Why Evolink chose Odoo over a heavier ERP, and Dynapps over a bigger partner.
The trigger was scale catching up with the tooling. At roughly forty staff, the time lost across the separate systems had become too large to absorb, and the company decided to centralise everything in one ERP and move off its scattered tools. Two questions had to be settled in order, first the ERP, then the partner. The options on the table:
A heavier, tier-one ERP
Ruled out on cost. For an SME in Suisse romande the monthly licence has a direct effect on cash flow, and the big names priced themselves out for a company Evolink's size.
A bigger-name implementation partner
Set aside on fit. Evolink wanted proximity and human scale, a partner where you are not just a number, rather than being one account inside a large group.
Odoo, built with Dynapps
Odoo won on integrated functionality, cost and flexibility: with its own developers and very specific needs, Evolink wanted an open product it could shape, and above all simplicity. Dynapps, a few kilometres from one of Evolink's branches in Suisse romande, brought the human scale behind today's win-win relationship.
How the rollout really happened
How Evolink went live on Odoo in three months.
2024
Build begins with Dynapps.
Early 2025
Single go-live for the full platform, timed to the financial year to avoid switching ERP mid-year.
End 2025
Fully stabilised; now in complete production, with new modules being added.
How Evolink runs from quote to invoice on one Odoo platform.
The principle was simplicity: the most important modules first, under a tight deadline, without the old tools' scattered processes. A system the team would actually use, not another stack to fight.
One Odoo platform absorbed the separate tools: CRM, new to Evolink, plus quoting, project management, timesheets, invoicing, accounting, subscriptions, leave and overtime. The spine is the deal-to-cash chain: a CRM ticket becomes an offer, and on acceptance it spins up a project with milestones and auto-generated timesheets through to final invoicing. Project management went furthest, since that chain is the core of the business. The build ran about three months, with three Dynapps Switzerland consultants, one full-time internal developer and the CEO at roughly 20%.
Modules: CRM, quoting, project management, timesheets, invoicing, accounting, subscription management, leave & overtime
The discipline throughout.
Put the most important modules in first under a tight deadline, and resist scattering the company across a million complicated processes the way the old tools had. The point was a system Evolink's people would actually use, not another stack to fight.
Custom development under a three-month deadline, and the side effects it created.
The honest difficulty was technical, and it came from the company's own ambition. Because Evolink commissioned a lot of specific development, fixes had side effects: a change made to satisfy one need would surface a problem in another module, and the team would chase the knock-on across the platform. Compressed into three months and landing on a 1 January go-live, that made the early weeks genuinely stressful. The side effects were resolved fast, but only because Evolink's and Dynapps's teams worked them jointly and quickly.
There was a second weight that was organisational, not technical. Evolink had been burned before by a tool that went badly and had to be rolled back, so staff carried a real fear about whether Odoo would actually save them time, and after promising people improvement, the CEO felt he had no right to fail on this one.
What matters most to us is the partner's availability and that they understand the client's business.

The change shows up on both sides. Evolink does IT but not Odoo; Dynapps does Odoo but not IT, so over the engagement the two began working as a pair at shared clients, a genuine win-win with work flowing in both directions. The collaboration has continued past the rollout itself.
The numbers
What Evolink got from one Odoo platform.
Three months after the build began, Evolink ran on one Odoo across all four sites. The separate tools for quoting, projects, timesheets, subscriptions and invoicing are gone, the deal-to-cash chain runs in one place, and the billing that used to leak between systems is now captured.

From guessing across tools to one live view of the business.
The shift is in the question the CEO can now answer on demand. Before, the company worked blind between systems and asked which of these tools has the right number; now the question is what is the business actually doing this week, cash flow, unpaid invoices and the sales pipeline all visible on live dashboards, so a problem can be corrected as it appears rather than discovered at year-end.
If this sounds familiar, let’s talk.
Wherever your business is heading and wherever it's getting stuck, an expert who has run this kind of work is the right person to start with, before you commit to a direction or a platform.
