Marketing consultants send estimates or proposals before a retainer or project begins, often after a discovery call. Clients usually compare several consultants on price, deliverables, timeline, and how results will be measured. A clear quote helps show the value of your approach and avoids disagreements later.
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.

Name what the client receives, such as an audit document, a 12-month plan, or 8 email templates, so they know what the fee covers.
State which channels you will work on, such as search ads, email, and social, so the client does not assume everything is included.
Specify the number of calls, response times, and reporting schedule to set expectations on availability.
Limits on revisions and who signs off protect you from endless rework and delays.
List what you need, such as analytics access, brand assets, and timely feedback, since delays on their side affect your timeline.
Make clear that media budgets and software fees are separate from your fee and who pays them.
Define how progress will be measured and state that results depend on factors outside your control.

Typical US ranges. Rates vary by region, experience, and job size.
Present a basic, standard, and full option, such as audit only, audit plus plan, and audit plus plan plus 3 months of advisory. Clients tend to choose the middle option and feel in control of the decision.
Estimate your hours, then adjust for the business impact. A plan that guides a $500,000 ad budget is worth more than the same hours for a small local shop.
Show setup or strategy costs separately from monthly retainer fees so the client understands the ongoing commitment.
Quotes should expire in 14 to 30 days, since your availability and the client's situation change.
Detailed enough to cover scope, deliverables, timeline, and price on a few pages. Small clients prefer a short one to three page quote, while larger companies may expect background research and a longer document.
Quick quotes are normally free. If the proposal requires substantial research, such as a competitive analysis or audit, consider a paid discovery phase that can be credited against the full project.
Include a change clause in the quote. When requests go beyond the agreed deliverables, send a written change estimate and get approval before doing the extra work.
Yes, when scope is uncertain. State what drives the range, such as number of channels or rounds of revision, and agree on a cap or checkpoint so the client does not face an open-ended bill.
