How UK creative agencies take client calls off a mobile

If you run a UK creative agency, there's a good chance the client line is somebody's mobile. The account manager gave their number out on day one of the project because it was quicker than setting anything up, and eighteen months later it's in the client's email signature, a WhatsApp group and a Slack Connect channel nobody remembers creating. It isn't that you're disorganised. Briefs get logged, timesheets get tracked, feedback rounds get versioned. Client calls are the one channel that slipped, and I think I know why: the business phone a creative agency was supposed to install looked like it belonged in a call centre, and you'd rather live with the mess than with that.

The short answer: give every client-facing person a number that belongs to the agency, not to them, reachable from the laptop and phone they already work on, with a recording and a transcript of what was agreed. When an account moves to a new account manager, the number and the history move with it.

Why does the client line end up on a mobile?

I've sold business phone systems to UK small businesses since 2012, and the view I've come to is that how a tool looks and feels changes how people work with it. Most business software was built without anyone caring about that, and you can feel it the moment you open a meetings app to make a phone call.

That's why the mobile wins. An agency is full of people who chose their laptop, chose their typeface and chose the chair they sit in. Then the phone arrives, assigned, and it's the one thing on the desk nobody picked. The account manager's own phone is the only option in the room that feels like something they'd choose, so that's where the client line goes. Nobody decided it. It drifted there because the alternative felt worse.

The business phones on offer were built for a call centre, not a studio with a moodboard on the wall and pale timber desks, and for a long time an agency wasn't offered much else. So the mobile it was.

What does it cost when the client line is one person's phone?

It works, in the sense that calls get answered. It stops working the day that account manager is on annual leave, in a client workshop with their phone face down, or handing in their notice, and the client has no other way in.

The costs are specific to agency work. A change request made on a call has no record, and scope changes happen on calls more than in writing because it's quicker to talk a change through than to type it. Three weeks later, "the client asked for this" is a memory contest at invoice time. A handover between account managers loses the thread, because the new person inherits the written brief and a bit of hearsay, not what was actually said. And when someone leaves, the number leaves with them, so every client they looked after gets a "this is my new number" email and the agency goes back to routing calls by hand.

Then there's out of hours. When the only way to reach the team is one person's mobile, being unreachable becomes a choice that person makes on behalf of the whole agency, usually without meaning to, because their phone is on silent in a bag.

What should a business phone for a creative agency look like?

For a studio of five to a hundred people, the fix isn't the phone from the call centre. It's giving every client-facing person a proper number that's the agency's, not theirs, in the place they already work, with a record of what was said. Here's what that looks like on an ordinary Tuesday.

One number per client relationship, not per person's mobile. When the account moves from one account manager to another, the number and the history move with it, and the client never gets the "sorry, who's this?" moment mid-project.

Reaching the client without hunting for the right app. In Olatti you press a hotkey from wherever you're working, type a name, press enter, and it's ringing. There's no separate dialler to remember and no checking whether this client prefers WhatsApp, a video link or the landline this week.

A record of what was agreed. Recording is there, with searchable transcripts and summaries depending on the plan, so the scope conversation from three weeks ago is something you check rather than something you argue about from memory.

A call that survives leaving the building. Move a live call from your desk to your phone mid-sentence and walk into the workshop without the client noticing. Useful the day a call runs long and you'd rather not hang up on a client to get to a meeting.

And the recording stays on infrastructure the agency controls. Voice, transcription and summaries run in We UC's own data centres, not a third-party AI vendor's. For an agency holding client IP, unreleased campaigns and pitch decks, where a call recording lives isn't a small detail.

None of that is an IT project. It's a decision that client calls deserve the same rigour as the timesheets.

Why don't Teams and WhatsApp already cover this?

Teams and Zoom are in most agencies for internal meetings, and they're fine at meetings. The gap is calling as a daily habit: reaching a client in one step rather than opening the right app and finding the right thread, and having a record of what was said without digging through a specific meeting's files afterwards. If Teams Phone is the tool your agency has half-adopted, we've written the fuller comparison.

WhatsApp is the other default, because it's fast and everyone already has it. The trade-off is that the client conversation now lives on someone's personal device, on their personal number, outside anything the agency can see or keep. That trade-off is covered in more detail here if it's the one your studio is living with.

The one relationship to fix this week

You don't need to sort every client's phone habits in one go. Pick the one costing you the most right now, usually the account manager about to go on leave or the account about to change hands, and give that relationship a number that belongs to the agency before the gap opens. The rest can follow once the first one's working.

Olatti exists because I don't think the phone has to be the ugliest thing on the desk. If you'd like to see what a modern business phone for a team like yours looks like, have a look, or join the waitlist and I'll bring you in early.
