Management consultants send a proposal or quote after an initial discovery conversation and before signing a statement of work. Clients usually compare scope, timeline, team, and total fee across two or three firms, and they pay close attention to what is excluded. A good estimate frames the problem, the approach, and the price in a document that can double as the contract.
When to use estimates: Use estimates to provide project quotes and get client approval before starting work. Once approved, convert your estimate to an invoice with one click to collect payment.

Confirms you and the client agree on what success looks like, which prevents disputes over whether the work met its goal.
A written report, a slide deck, a financial model, and a workshop are priced differently, so name each one.
Sets expectations for when work starts, when you need client input, and when each milestone is due.
Delays often come from slow data, unavailable stakeholders, or missing approvals, so list what the client must provide and by when.
State the number of interviews, workshops, review rounds, and any implementation support not included, so extra work is clearly out of scope.
Spell out whether the price is fixed, capped, or time and materials, and when each installment is due.
Clarifies whether travel and other costs are included, billed at cost, or capped, avoiding surprises on the final invoice.

Typical US ranges. Rates vary by region, experience, and job size.
A project that saves a client $200,000 a year can support a larger fee than hours alone suggest. Ask about the cost of the problem during discovery and anchor your price to it.
Present a basic diagnostic, a diagnostic with a plan, and a full engagement with implementation support. Options shift the discussion from whether to hire you to which scope fits.
Add a buffer of 10% to 20% for projects where data quality or stakeholder availability is uncertain, or use a phased quote with the second phase priced after the first.
State that the quote holds for 30 days. This protects you if your availability or the client's scope changes.
Short proposals after an introductory call are usually free. If the client wants a detailed diagnostic, a custom scoping study, or significant upfront analysis, charge a paid discovery phase and credit it against the full project if they proceed.
Detailed enough to define deliverables, timeline, assumptions, and price, usually two to five pages. Avoid listing every task, since that invites line-by-line negotiation of your fee.
Usually not. Showing hours invites the client to haggle over the rate instead of the value. You may reference an hourly rate for work outside the agreed scope or for change requests.
Use a written change order that describes the added work, the cost, and the effect on the timeline. Get approval before doing the work, and bill it as a separate line item.
Use the Management Consultant invoice template to bill the client, or convert this estimate once it's approved.
