Cybersecurity consultants send a written quote or proposal before any engagement, often after a scoping call. Clients usually compare price against scope, methodology, certifications such as OSCP or CISSP, and report quality, so the proposal needs to make scope and deliverables obvious.
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.

Price depends on the size of the attack surface, and a defined list prevents disputes over what should have been tested.
Clients need to know the depth of testing and what standard it follows, especially if an auditor will review the report.
Sets limits on risk and avoids liability if something outside the agreement is affected.
Testing can disrupt production, so timing and escalation paths must be agreed in advance.
Clients often expect a specific output for an audit or customer request, and this defines what the fee covers.
Avoids arguments over whether fixes are verified at no additional cost.
Delays caused by missing access are a common source of overruns, and this gives you grounds to adjust the schedule or fee.

Typical US ranges. Rates vary by region, experience, and job size.
Estimate testing days, reporting days, and project management time, then apply your day rate. A small app with complex authentication can take longer than a large flat network.
Present a basic vulnerability scan, a standard penetration test, and a deeper test with retest and remediation support. Clients often choose the middle tier and see exactly what extra money buys.
Report writing frequently takes as long as the testing itself. Include it in the fee so you are not discounting your own time.
Rates and availability change, so set an expiration of 30 days. Note that scope changes after acceptance will be quoted separately.
Offer a short paid discovery or scoping phase billed hourly or as a small flat fee. Use the results to quote the full engagement. Alternatively, quote a not-to-exceed amount with clear assumptions.
Yes. A 25-50% deposit due at signing is common for fixed-fee projects and secures the testing slot. State it in the quote along with the payment schedule.
Usually yes. A quote shows price and scope, but a master services agreement or SOW covers authorization, confidentiality, liability limits, and data handling. Many consultants combine the quote and SOW into one signed document, and having a lawyer review your template is a good idea.
Reduce scope rather than your rate. Remove the retest, narrow the target list, or switch to a lighter assessment. This keeps your day rate intact and the client gets a clear picture of what they are giving up.
