Proposals that win accounts

Agency pitches are competitive. Your proposal needs to look better, read clearer, and close faster than whoever else is in the mix. Prosperus gives you the infrastructure to do that at scale.

Team collaboration

Up to 3 users on the Pro plan. Your account manager builds the proposal, your strategist checks the pricing, your MD approves before it goes. No single point of failure.

Multi-package pitches

Present Retainer, Project, or Hybrid options side by side. Clients see the full picture and self-select. You stop losing accounts because the budget conversation happened too late.

Case studies at scale

Build a library of your agency’s work and drop the relevant campaigns into any proposal. No more last-minute scrambling for the right screenshot.

White-label ready

The proposal reflects your brand, not ours. Logo, colours, fonts — everything. Clients see an agency document, not a SaaS product.

Pipeline visibility

See every proposal out the door, its status, and the total pipeline value. Know which accounts are warm, which are cold, and where the team should focus.

AI that knows your agency

Set your tone, your capabilities, your USPs once. The AI drafts new proposals using that context every time. Faster pitching, consistent positioning.

The pitch that looks like you mean it

Generic proposals lose agency pitches. Not because the pricing was wrong or the strategy was weak — because the document looked like it was assembled in an hour. Clients notice.

Prosperus proposals are designed to look like a team worked on them. Because with the Pro plan, one does.

Retainers need to be proposed properly

Monthly retainers are the backbone of agency revenue, but they’re often undersold. A vague “£X per month for ongoing support” leaves clients comparing apples and oranges across agencies.

A properly scoped retainer — with deliverables listed, a payment schedule, and a signature attached — is harder to argue against and easier to renew.
