Marketing agency project management software for retainers and monthly deliverables.

Where marketing retainers leak

The retainer runs out before the month does

A 20-hour SEO retainer is gone by the 18th because two extra blog briefs and a landing page tweak slipped in. Nobody saw the meter until the invoice was due.

Every month is rebuilt from scratch

The same twelve social posts, four articles and one report get re-planned by hand each month, so a missed deliverable only shows up when the client asks for it.

Clients can't see what they're paying for

Reports sit in email threads and the monthly invoice arrives without context, which makes every renewal conversation start with “what did we get?”

01

Every channel in one inbox

Email lands beside the client record on every plan; texts, calls and voicemail join it from Voyager, with AI call summaries from Specialist.

A portal clients actually check

How a marketing agency runs a retainer month in Workspace369

01

Set the retainer up once

Choose an hour-bank, fixed monthly or prepaid retainer for the client, and put the recurring invoice on card autopay the client agrees to. Both are on every plan.

02

Plan the month's deliverables

Each deliverable is a task with a time estimate and an owner, grouped in the client's project. From Voyager, the Gantt timeline shows launch dates across clients, and on Commander the workload view shows who is over capacity.

03

Watch the hours as they're used

Timers and weekly timesheets with approvals feed the retainer's live hours meter, so an account manager sees a retainer at 80% before the month ends and can raise it with the client.

04

Show the client the month

Share the monthly report file and the invoice in the client's private, branded portal. On Specialist, project and customer profitability show which retainers actually make money.

What a marketing agency uses in Workspace369

  • Retainer visibility: can an account manager see hours used against the retainer mid-month, not only at invoice time?
  • Repeat work: count how many clicks it takes to plan next month's deliverables for one client.
  • Reporting: Workspace369 has no native Google Ads, Meta or analytics connection, so check how your performance reports reach the client.

True all-in-one system

It beautifully combined my CRM, team calendar, and billing tools so I could finally stop paying for a bunch of separate software subscriptions
