Retainer plans provide clients with predictable monthly capacity at a fixed cost. They’re the foundation of the billing system, defining how much time and budget each client has available.

What Is a Retainer Plan?

A retainer plan is a template that defines:

Monthly Hours

How many hours of work the client gets per month

Monthly Cost

The fixed retainer fee charged each month

Sold Day Rate

Calculated profitability metric (cost ÷ hours ÷ 7.5)

Plan Name

The tier name (e.g., “Starter”, “Growth”, “Scale”)
Plans are reusable templates—multiple clients can be assigned to the same plan, or clients can have custom overrides for special arrangements.

Standard Plan Tiers

Most agencies set up tiered plans for different client sizes:
PlanMonthly HoursMonthly CostSold Day RateBest For
Starter20 hours£2,000£750/daySmall clients, maintenance work
Growth60 hours£5,000£625/dayStandard ongoing clients
Scale120 hours£9,000£563/dayLarger clients, multiple projects
Enterprise200 hours£14,000£525/dayMajor accounts, dedicated capacity
These are example tiers. Each agency sets their own plan structure, pricing, and naming based on their business model.

Why Day Rates Decrease with Volume

Notice that larger plans have lower day rates? This is standard tiered pricing:
  • Volume discount: Clients committing to more hours get better rates
  • Efficiency at scale: Larger engagements reduce context switching
  • Relationship value: Bigger clients are worth better pricing
However, the absolute revenue and profit are higher on larger plans.

How Plans Work

Assignment

Clients are assigned to plans when they’re created or updated:
  1. Choose a plan from the dropdown during client setup
  2. Optional overrides allow custom pricing per client
  3. No plan is also valid—some clients are project-only (no retainer)

PM Deduction

When a client is assigned a plan, 15% of the hours are automatically reserved for project management:
Net Available Hours
Net Hours = Raw Hours × 0.85
Example:
  • Plan: 60 hours/month
  • PM deduction: 9 hours (15%)
  • Available for deliverable work: 51 hours
This covers:
  • Sprint planning
  • Client communication
  • Status updates
  • Scope management
  • QA coordination
The PM deduction happens at allocation, not per task. Individual task estimates show only design/development time—PM overhead is factored into the overall monthly budget.

Monthly Cycle

Plans operate on calendar-month cycles:
1

Month Start

Full allocation becomes available (e.g., 60 hours) PM deduction applied (e.g., 51 hours net available)
2

During the Month

Work is completed and billable hours deducted from allocation Client sees real-time remaining balance
3

Month End

Unused hours expire (no rollover by default) New allocation starts next month

Plan Overrides

Plans are templates, but clients often need custom pricing. Plan overrides allow client-specific adjustments:

When to Use Overrides

A client negotiates custom pricing based on their specific situation.Example: Client wants 60 hours at £4,500/month instead of standard £5,000
Long-standing clients keep old pricing when plans change.Example: Plan increased to £5,500, but existing client stays at £5,000
Unique situations like:
  • Non-profit discounts
  • Strategic partnership pricing
  • Trial periods with reduced rates
Short-term changes:
  • Reduced hours during quiet season
  • Increased capacity for project push
  • Bridge pricing during transitions

How Overrides Work

When creating or editing a client, you can override:
Overrides the plan’s standard hours allocation.Example:
  • Plan: Growth (60 hours)
  • Override: 75 hours
  • Client gets 75 hours/month instead of 60
Priority:
  • If override is set → use override value
  • If override is null → use plan value
  • Overrides are optional—leaving blank uses the plan default

Managing Plans

Creating Plans

Plans are managed in the Admin section:
  1. Navigate to Admin → Plans
  2. Click “Add Plan”
  3. Enter:
    • Name: The tier name (e.g., “Growth”)
    • Monthly Hours: Hours allocated (e.g., 60)
    • Monthly Cost: Retainer fee in pounds (e.g., 5000)
  4. Save
The sold day rate is calculated automatically.

Editing Plans

When you edit a plan, all clients on that plan are affected unless they have overrides:
  • Edit hours → All clients get new allocation (next billing period)
  • Edit cost → All clients pay new fee (next billing period)
  • Clients with overrides are unaffected
Be careful when editing plans with many clients. Consider:
  • Communicating changes to affected clients
  • Whether to grandfather existing clients (use overrides)
  • Impact on profitability metrics

Deleting Plans

When deleting a plan, you must handle existing clients: Option 1: Assign Replacement Plan
  • Select another plan to move clients to
  • All clients on deleted plan are reassigned
  • Overrides are preserved
Option 2: Remove Plan Assignment
  • Clients become “no plan” (project-only)
  • Existing retainer data is preserved for history
  • Requires manual reassignment later
You cannot delete a plan with clients unless you specify what to do with them. This prevents accidental data loss.

Project-Only Clients

Not all clients need retainers. Project-only clients have:
  • No plan assigned (planId = null)
  • No monthly allocation
  • Work is quoted and billed per project
  • Still tracked in CharleOS for capacity planning
This is useful for:
  • One-off projects
  • New clients in trial phase
  • Fixed-price project work
  • Clients transitioning off retainers

Plan Utilization

Plans include utilization tracking to help with client management:

Utilization Calculation

Utilization = (Billable Hours Used ÷ Net Available Hours) × 100
Example:
  • Plan: 60 hours (51 hours after PM deduction)
  • Used: 45 hours
  • Utilization: 45 ÷ 51 × 100 = 88%

Utilization Bands

RangeStatusIndicatorWhat It Means
0-75%Normal GreenHealthy usage, capacity available
75-90%Approaching AmberGetting close to allocation
90-100%Near Limit AmberAlmost at capacity
Greater than 100%Over RedExceeded allocation, upsell opportunity

When Utilization Is Too Low

Under 50% consistently:
  • Client isn’t using their allocation
  • Consider downselling to smaller plan
  • Find opportunities to use remaining hours
  • May indicate engagement issues

When Utilization Is Too High

Over 90% consistently:
  • Client needs more capacity
  • Upsell to larger plan
  • Scope discussions needed
  • Risk of client dissatisfaction

Real-World Examples

Example 1: Standard Client on Growth Plan

Setup:
  • Plan: Growth (60 hours, £5,000/month)
  • No overrides
  • PM deduction: 9 hours (15%)
  • Net available: 51 hours
Month 1:
  • Used: 42 hours (82% utilization)
  • Status: Healthy
Month 2:
  • Used: 56 hours (110% utilization)
  • Action: CSM discusses upsell to Scale plan

Example 2: Client with Custom Pricing

Setup:
  • Plan: Growth (60 hours, £5,000/month)
  • Override: 75 hours, £5,500/month
  • Effective sold day rate: £550/day (vs plan’s £625)
  • Reason: Long-term client, negotiated volume discount
Result:
  • Client gets 75 hours/month
  • Pays £5,500/month
  • Plan can be edited without affecting this client’s pricing

Example 3: Non-Profit Discount

Setup:
  • Plan: Growth (60 hours, £5,000/month)
  • Override: Cost only → £3,500/month
  • Hours stay at 60
  • Reason: Charitable pricing
Result:
  • Client gets standard 60 hours
  • Pays £3,500 (30% discount)
  • Effective sold day rate: £437.50/day

Plan Strategy Considerations

When designing your plan structure:
Too few (1-2 plans):
  • Simple to manage
  • May not fit all client sizes
  • Miss upsell opportunities
Too many (6+ plans):
  • Confusing for clients
  • Analysis paralysis
  • Hard to manage
Sweet spot: 3-5 tiers covering small, medium, large, and enterprise
Larger plans should have:
  • Lower per-hour rates (incentive to commit more)
  • But higher absolute revenue and profit
Example:
  • Starter: £100/hr × 20 hrs = £2,000 revenue
  • Growth: £83/hr × 60 hrs = £5,000 revenue ✓
Use names that:
  • Suggest growth (Starter → Growth → Scale)
  • Are client-friendly (not internal jargon)
  • Allow for additions (don’t use “Ultimate” too early)
Avoid:
  • Tier 1, Tier 2 (boring, no emotion)
  • Names that box you in (can’t add tiers)
Your smallest plan should be:
  • Large enough to be profitable
  • Small enough to be accessible
  • A natural entry point for new clients
If too small: Not worth the overhead If too large: Barrier to entry for new clients
