You Build Marketing Systems for Clients.
Now Build One for Your Own Agency.
Marketing agencies are world-class at building growth systems for their clients — and notoriously poor at building them for themselves. New business follow-up that happens when someone remembers. Client reporting that takes a full day every month. Proposals sent from one person's inbox. Revenue that fluctuates with the client count. One Core gives marketing agencies the platform to run their own business with the same operational discipline they bring to their best client engagements — and a new revenue stream from reselling the platform itself.

The Challenge
The Best Marketing Agencies in the World Have One Thing in Common: They Practice What They Preach. Most Don't.
There's a painful irony at the heart of most marketing agencies. They tell clients to respond to leads within 60 seconds — and take two days to follow up their own enquiries. They build automation workflows for clients — and manage their own operations through email, WhatsApp groups and spreadsheets. They present data-driven reporting to clients — and compile their own reports manually every month. One Core gives agencies the platform to operate with the same sophistication they sell to others — and to resell the platform to clients as an additional, highly profitable revenue stream.
Sound Familiar?
New business leads from referrals and campaigns receive inconsistent follow-up — whoever gets to the inbox first deals with them
Client onboarding is chaotic — contracts, briefs, access credentials and campaign setup managed across email threads
Monthly reporting is a full-day task involving manual exports from multiple platforms, compiled into PDFs that clients rarely read
Client communication is scattered across individual team members' email inboxes with no central CRM record
Team task management and campaign delivery tracking lives in a separate tool that doesn't connect to client communication or billing
Revenue growth is linear — every pound of new income requires more team time, more hours and more overhead
How One Core Helps
Built for the Way Marketing Agencies Actually Operates
New Business That Actually Gets Followed Up
Every new business enquiry — from referrals, your website contact form, LinkedIn or a speaking event — enters your CRM automatically. One Core triggers an immediate, professional acknowledgement and assigns the lead to the right account manager. Automated follow-up sequences ensure every prospect hears from you at the right intervals across weeks or months. No lead goes cold because someone was too busy with a client deliverable.
Client Onboarding in Hours, Not Days
When a new client signs, One Core triggers a complete onboarding sequence automatically — NDA and contract sent for electronic signature, strategy questionnaire delivered via WhatsApp, campaign brief form sent, kickoff call scheduled in the calendar and a welcome email that sets expectations for the first 30 days. Your client's first impression is polished, professional and completely systematic.
Proposals That Close in Hours, Not Weeks
Build professional, branded proposals directly inside One Core. Send them with a single link. Track when they're opened, which sections they spent time on and whether they forwarded it to a decision-maker. Automated follow-up at 48 hours, 5 days and 10 days ensures every proposal gets the right attention — without your senior team having to remember to chase.
Centralised Client Communication — No More Scattered Inboxes
Every client conversation — email, WhatsApp, campaign updates and approvals — lives in one unified inbox with full history. When an account manager is on holiday, anyone can pick up a client conversation with complete context. No client ever feels like they're dealing with a fragmented team. No message ever gets lost in someone's personal inbox.
Automated Client Reporting That Builds Retention
Monthly performance reports that used to take 6 hours per client now generate automatically from connected data sources. Send clients a branded dashboard link — live, not a PDF screenshot — so they can see campaign performance, leads generated, revenue attributed and KPI progress in real time. Clients who can see their results don't question the invoice. And clients who can see their results renew.
Campaign Delivery Built Into the Same Platform
Build and launch email campaigns, WhatsApp broadcasts and Meta ad campaigns for clients directly inside One Core. Results feed back into the same platform where client conversations live. Your team has one login to manage campaign briefs, execution, performance and client communication — reducing context-switching and errors significantly.
Add a Recurring Revenue Stream by Reselling One Core
Every client who uses disconnected tools — a separate CRM, a different email platform, a booking tool, a payment processor — is a client you could consolidate onto One Core under your agency's brand. Charge a monthly platform fee on top of your retainer. Earn recurring revenue per client that compounds as you grow. A 10-client agency reselling One Core at £200/month per client generates £24,000 in additional annual revenue before a single campaign is briefed.
Team Management That Scales With Headcount
Assign campaigns to team members, set deadlines, track progress, manage capacity across accounts and view productivity across the agency from one management dashboard. When you hire your next account manager, their workspace is ready within minutes — with permissions set, client accounts assigned and workflows configured. Scaling stops being operationally painful.
