Professional Services Case Study: From Spreadsheets to Real-Time Project Profitability
UNIFYX


Client context

A 25–40 person consulting/engineering firm running projects and invoicing through spreadsheets and fragmented systems.

Company type: professional services firm (consulting / engineering / expert services)

Size: 25–40 employees (consultants/engineers + support team)

Model: projects billed fixed-fee, time & materials, or a mix (retainer + delivery)

Organization: rapid growth, increasing client demand, rising project complexity.

Initial situation (tooling):

  • Sales tracking via spreadsheets + emails + disconnected tools

  • Projects managed in files or non-integrated tools

  • Time & expenses captured manually (sometimes only at month-end)

  • Invoicing delayed due to approvals and manual consolidation.

Problems (pain points) and symptoms

Disconnected tools and manual workflows created blind spots in profitability, delayed billing, and weak cross-team coordination.

Management control & profitability

  • No real-time visibility on project margins, budget vs actual variances, or profitability by client
  • Hard trade-offs: project overruns are “felt,” but recognized too late.

Execution & capture (timesheets / expenses)

  • Timesheets and expenses are incomplete or submitted late
  • Administrative workload falls on consultants
  • Risk of errors and non-rebilled costs.

Cross-team coordination

  • Sales sells → Delivery discovers constraints too late
  • Finance invoices → Delivery has not validated deliverables
  • Contracts, SOWs, change orders: information scattered.

Invoicing & cash

  • Inconsistent invoices (formats, rules, terms)
  • Recurring delays → cash flow pressure
  • Higher DSO (Days Sales Outstanding) because invoicing happens late.

Business objectives (what the client wants)

Create a scalable lead-to-invoice operating model with real-time profitability visibility, faster billing, and less admin work.

  • Real-time visibility into project profitability and team performance
  • Standardize the full cycle: lead → contract → delivery → invoice
  • Speed up invoicing (and reduce errors)
  • Reduce admin work for consultants
  • Implement KPIs and operating rhythms (utilization, margin, WIP, forecast).

UnifyX approach

Structure first: we design the operating model (workflows, roles, KPIs) before implementing any system—so adoption is fast and outcomes are measurable.

Step 1 — Rapid diagnostic (1–2 weeks)

  • Map the service lifecycle: Lead → Deal → Contract → Plan → Deliver → Invoice → Collect

  • Identify breakpoints (Sales/Delivery/Finance handoffs, approvals, missing data)

  • Review current indicators vs expected ones.

Deliverable: Diagnostic + “Operating Model Blueprint” (processes, roles, approvals, KPIs).

Step 2 — Operating model design (2–3 weeks)

  • Define target workflows for:

    • qualification / proposal / contract

    • project kickoff / milestones / status reporting / deliverables

    • timesheets & expenses (rules + approvals)

    • invoicing (fixed-fee, time & materials, milestones, change orders)

  • RACI matrix (who does what, who approves what)

  • KPIs and rhythms: pipeline review, project review, margin review, capacity & workload forecast.

Deliverable: Process maps + RACI + KPI pack + business rules.

Solution implemented (functional scope)

An integrated lead-to-invoice system covering CRM, delivery execution, time & expenses, automated billing, and profitability reporting.

CRM & Sales

  • Lead/opportunity management

  • Standardized stages + scoring

  • Pipeline forecasting

  • Interaction history + documents.

Quotes, SOWs & contracts

  • Quote/contract templates, terms, appendices

  • Approval workflow (minimum margin, discounts, exceptions)

  • Change order management.

Project delivery

  • Projects structured by milestones / phases / tasks

  • Billable milestones with attached deliverables

  • Budget vs consumed tracking.

Timesheets & expenses

  • Simple entry (mobile/desktop)

  • Rules: allocation, categories, rebilling

  • Manager approvals + monthly cut-off.

Automated invoicing

  • Billing for:

    • time & materials

    • fixed-fee by milestone

    • monthly retainer

    • reimbursable expenses

  • Invoice generation driven by rules & approvals

  • Fewer errors and better standardization.

Dashboards & profitability

  • Margin by project / client / team

  • Utilization (billable vs non-billable)

  • WIP (work in progress)

  • Capacity and workload forecasting.


Outcomes & impact

Earlier detection of project overruns, shorter billing cycles, and improved utilization through consistent execution.

Margin visibility & early warning

  • Earlier detection of projects drifting off-track

  • Better decisions: staffing adjustments, renegotiation, change orders.

Faster and more reliable invoicing

  • Reduced “month-end close → invoice sent” cycle time

  • Standardized rules → fewer disputes.

Reduced administrative workload

  • Consultants spend less time on manual reporting

  • Finance saves time on consolidation.

Improved collaboration

  • Sales → Delivery: structured handoff

  • Delivery → Finance: “invoice-ready” data.

Steering KPIs

A focused KPI set to monitor profitability, utilization, billing speed, and delivery predictability—weekly and monthly.

  • Utilization rate (per consultant, team, month)
  • Project gross margin (planned vs actual)
  • Budget burn (% consumed)
  • Invoice cycle time (period close → invoice sent)
  • DSO (Days Sales Outstanding)
  • Timesheet compliance (completion rate + submission delay)
  • WIP (work performed but not invoiced)
  • Forecast accuracy (capacity & revenue).

ROI model

A focused KPI set to monitor profitability, utilization, billing speed, and delivery predictability—weekly and monthly.

Illustrative assumption for 30 employees, including 22 billable staff.

  • Annual revenue: $2.5M
  • Average invoicing delay: 10 days
  • Admin time saved:

    • 22 consultants × 1h/week × 48 weeks = 1,056 hours/year
    • internal value at $80/hour ≈ $84,480/year
  • Reduced leakage (unbilled time/expenses): 1% of revenue = $25,000/year
  • Cash impact (faster invoicing): improved cash position (depending on DSO), not counted as profit but significant.
  • Conservative estimated annual benefit: $84,480 + $25,000 = $109,480/year
  • If total project cost (implementation + adoption) ≈ $35k–$70k, payback is often < 12 months.

Why it worked 

A focused KPI set to monitor profitability, utilization, billing speed, and delivery predictability—weekly and monthly.

  • Structure first: real workflows, not a tool-centric implementation
  • Teams adopted because:

    • less friction in time/expense entry
    • simpler invoicing
    • clear rules and consistent approvals
  • Leadership finally had an economic view: margin, utilization, WIP, forecast.

Why it worked 

Because we started with structure—workflows matched real operations, making adoption fast and performance measurable.

Phase 0 — Diagnostic (1–2 weeks)

  • Workshops + mapping + blueprint

Phase 1 — Foundations (2–4 weeks)

  • CRM + quotes/contracts + project structure + roles + rules

Phase 2 — Delivery & Finance (3–6 weeks)

  • timesheets/expenses + invoicing + dashboards

Phase 3 — Adoption & optimization (4–8 weeks)

  • Training, operating rhythms, continuous improvement, stabilized KPIs.

Risks & mitigations

Because we started with structure—workflows matched real operations, making adoption fast and performance measurable.

  • Timesheet resistance → simplify capture + clear rules + minimal but useful reporting

  • Historical data → “smart” migration (active clients/projects only at first)

  • Billing variations → standardize 80%, manage 20% exceptions via approval workflow

  • Lack of executive sponsor → set up a steering committee + weekly rituals for 6–8 weeks.
