COLO gives small marketing agencies a single workspace for scoping retainers, running multi-client projects across content, social, and paid media, communicating with clients in context, and invoicing — without spreading work across Asana, a separate proposal tool, Slack Connect, and a billing app.
TL;DR
Small marketing agencies use COLO to scope retainers, run multi-client projects across content, social and paid media, talk to clients in context and invoice. Multi-client project workspaces give the team one view of every account, proposals lock the retainer scope so extra requests are visible rather than absorbed, and client chat sits against the work instead of in Slack Connect.
Who this is for
You are a two-to-ten-person marketing agency running monthly retainers for five to fifteen clients, plus the occasional one-off project (a campaign launch, a website refresh, a brand sprint). Most clients expect monthly content, monthly reports, and a team they can reach without remembering which platform they are on.
The friction tends to be the same shape:
- Each client lives in three of your tools. Project plan in Asana, files in Drive, conversations in Slack Connect or email, billing in a fourth system. Nobody on your team has the full picture in one place.
- Retainer scope creep is everyone's problem. The retainer says four blog posts a month; the client also asked for a landing page, two social campaigns, and a webinar deck — and your team did all of it because nobody pushed back.
- Reporting is the Friday-night job. Pulling numbers from three platforms into a deck for fifteen clients is a recurring weekend tax.
Three features marketing agencies use every week
Multi-client project workspaces
Run each client as a project (or one project per retainer plus per campaign) with milestones, tasks, owners, and deadlines. With COLO's project system, you can implement your project plan by assigning tasks, allocating resources, and coordinating activities. Track project performance against the plan, provide regular updates on progress and milestones, and communicate any changes. Your team sees workload across clients; the client sees only their project.
Proposals that lock the retainer scope
Send a branded proposal that lists what is in the monthly retainer (four blog posts, eight social posts, one campaign report) and what is not. Win more clients with branded proposals and a modern way to collaborate. Out-of-scope requests get a separate change-order proposal, so the team is not absorbing the cost of the "could you also" requests.
Client chat in context
Conversation, briefs, and feedback live against the project they are about, not in a Slack channel the new account manager cannot find on day one. Integrating chat functionality into an application offers numerous advantages, enhancing both user experience and operational efficiency. By incorporating chat, an application can significantly improve client satisfaction, streamline operations, and foster stronger relationships. When a client onboards or off-boards, the conversation history stays attached to the client record.

A typical engagement in COLO for a marketing agency
- Enquiry — a prospect fills your contact form or comes through a referral; the lead becomes a client record with the discovery notes attached.
- Onboarding — you send a branded proposal scoping a three-month retainer with deliverables, fee, and start date; the client signs and pays the first month; the workspace opens with the retainer milestones, the first month's content calendar, and the client's brand assets pre-loaded.
- Delivery — content, campaigns, and reports run as tasks against the retainer; the client comments in context; monthly reports attach to the project record.
- Payment — the recurring monthly retainer invoice fires on the first; one-off campaigns are invoiced as they ship; the finance dashboard shows revenue and margin per client.
How marketing agencies use COLO today
Monday morning, the account leads open their workspace to a dashboard of ten active retainers — content calendars for the month rolling out, two clients waiting for monthly reports, one campaign launching Wednesday, and three change-orders queued from Friday's calls. Each client sees only their own project portal — branded on the agency's domain on the Grow plan. The team sees workload across clients, surfacing capacity issues before they become a missed-deadline crisis.
Through the week, content, campaigns, and reports run as tasks against the right retainer; the client comments in context against the piece they are reviewing; the chat thread for client communication lives next to the work it is about. When a senior copywriter goes on leave and her work passes to a colleague, the colleague reads the client record once — brief, brand-style sheet, prior campaigns, chat history — and is operational on the account in an hour, not a week.
By the end of the month the ten recurring retainer invoices fire automatically; one-off campaign invoices ship as they close. The finance dashboard shows revenue and effective margin per client — and the retainer that has quietly been absorbing too many senior hours becomes visible. The change-order conversation, which used to feel awkward, becomes a routine pricing tool because the data behind it is on screen.
What it costs vs your current stack
Most small marketing agencies carry a four-tool stack — a project tool, a client-comms tool, a separate billing app, and a CRM or notes tool. The monthly bill comes to roughly $130–220 before the first retainer of the month is invoiced. COLO replaces the four with one workspace.
| Tool | Plan | Cost/month |
|---|---|---|
| Current 4-tool stack | Asana + Slack Connect + QuickBooks + HubSpot | ~$180 |
| COLO Solo | Free | $0 |
| COLO Pro | Per user/mo | $18 |
| COLO Grow | Per user/mo | $24 |
You swap a $180/month stack for one tool that already does this work. Pro covers a small team up to 5 users; Grow adds the white-label client portal on the agency's custom domain.
FAQ
Q: Can my team see workload across all clients, while clients only see their own project?
Yes. The team has a cross-client view; each client sees only their own project portal, with only the bits you choose to share.
Q: How do I handle out-of-scope requests on a retainer?
Issue a separate change-order proposal against the same client record. The client signs and pays for the extra scope; the original retainer keeps its agreed deliverables and budget.
Q: Can I onboard a new account manager without losing the client conversation history?
Yes — conversations, files, and decisions live against the client record, so a new team member has the full context on day one.
Q: How does COLO compare with running Asana plus Slack Connect plus a separate billing tool?
For most small marketing agencies, the all-in-one stops the copy-paste between tools and gives one client a single login. See the Asana comparison and our post on the hidden cost of poor workflow visibility.
Q: Can the client portal carry our agency's brand and domain?
Yes — the Grow plan includes a white-label client portal on your custom domain. See our pricing for plan details.
Q: How do we onboard a new account manager onto a live retainer without losing context?
The client record holds the brand guidelines, past campaigns, active project board, and chat thread. A new team member opens the profile and is operational in an hour, not a week.
Q: Can I run campaign and content retainers with different invoice schedules?
Yes. Each client holds its own billing setup — a recurring monthly retainer for content, a per-campaign invoice for the paid-media work, and an ad-hoc invoice for one-off projects. All live against the same client record.
Q: How do we share monthly reports with the client without a fifteen-slide PDF?
Reports attach to the client portal as a hosted summary — the client sees the metrics, the deliverables, and the next-month plan in their own portal. The PDF export is one click if they prefer the file format.
Q: Can we invoice in the client's currency for international retainers?
Yes. Each client record holds the invoicing currency; the recurring retainer issues in that currency; the finance dashboard converts to the agency's reporting currency on the day the payment cleared.
Q: How do we track senior versus junior hours per retainer for capacity planning?
Time entries log against tasks; the time-allocation view rolls hours per team member, per client, and per type of work. The retainer absorbing too much senior time becomes visible without rebuilding a spreadsheet.
