How to write a commercial proposal: types, structure, offer

A commercial proposal is a text where you offer a service or product and invite the next step: a call, a meeting, an invoice. Most often it goes by email; less often via messengers and social.

Below: types by audience “temperature,” working structures, and how to write the headline, offer, benefits, and price. Blasts to bought lists and aggressive spam are out of bounds — write clearly and only where you were asked or have a lawful basis to contact.

Three proposal types

Cold — audience with no prior contact. Often a template; goal — reply and qualify. Warm — there was already a touch (lead, meeting, download): more personalization; job — keep the thread and move to a deal.

Hot — after discussing terms: timing, scope, price, responsibilities. Always personal. Goal — lock agreements and close.

Match tone to temperature:

  • cold — problem + benefit + short CTA
  • warm — reference to the last touch
  • hot — deal specifics and the next step

A structure that works

Working frame: headline → offer/attention → substance → arguments and price → objections → call to action → contacts. For cold mail you can merge benefit and headline in the first lines.

Alternatives differ in details (footer, P.S., company strengths block), but the logic is the same: why read → what they get → why you → how much → what to do next.

Long cold walls of text more often go to trash. Facts, numbers, and short paragraphs raise reply odds.

Blocks by purpose:

  • headline with a fact or audience problem
  • lead: problem → solution in 1–2 sentences
  • service scope / product specs without fluff
  • differences and offer (timing, package, bonus) for the customer’s pain
  • price with reasoning
  • CTA and contacts

How to write so they finish reading

In the headline and lead — the reader’s benefit, with numbers if possible. Avoid spam clichés like “free / today only / guaranteed win” — they cut both trust and deliverability.

Don’t pressure or decide for the customer. The job is clear information; the decision stays theirs. Fewer judgments (“better,” “cheaper”), more checkable differences.

Price must be explained: what the money pays for. The more expensive — the more detail on scope. Close with a positive concrete CTA (call, reply, pick a package), not a vague “looking forward to cooperating.”

FAQ

Is a commercial proposal just any promo email?

Basically yes if there’s an offer. But a strong proposal answers the recipient’s job and leads to a clear action — not “just warming.”

How does cold differ from hot?

Cold — little context, shorter, benefit up front. Hot — after talks: timing, scope, price, next step personalized.

Do I need a price in a cold proposal?

Often yes — at least a range or packages. Hiding price to force a lead form filters worse and annoys more.

Can I write “best” or “cheapest of all”?

Better facts and measurable differences. Vague claims convince poorly and near-spam words hurt deliverability.

How long should the letter be?

Cold — short. Warm/hot can be longer if deal details matter. The point is they read through to the CTA.

Is a USP required?

Useful to state how you differ for this audience. A USP with no link to the customer’s pain is just a slogan.

Proposals go out — and replies stall on vague price and soft CTA?

We’ll match cold/warm/hot tone, put benefit and price up front, and end with one clear next step.
