Proposal software for freelancers

Proposal software for freelancers: send it, get it signed, invoice it.

A freelance proposal only matters once the client says yes. Workspace369 builds proposals from your services, shares them as a link the client can accept and sign, and converts the accepted proposal into an invoice, all on the client's record. Proposals and online signing are on every plan, from $29/month.

Key facts

Proposal software for freelancers at Workspace369 covers 10 areas, including proposals and quotes, catalog-based line items, online acceptance and signing.

The workflow runs in 4 steps, from "build from your catalog" to "convert it into an invoice".

Workspace369 starts at $29/mo for 1 seat, and the Commander plan includes 20 seats, and 120,000 AI tokens per month at $299/mo.

Additional seats cost $10 each; full pricing is public on the Workspace369 pricing page.

The problem

Where freelance proposals lose the deal

Every proposal starts from a blank page

Copying last month's document and editing prices by hand is slow, and slow proposals give the client time to ask someone else.

"Looks good" isn't a signature

An approving email doesn't record which scope and price the client accepted, which is exactly what you need when the scope grows later.

The invoice is retyped from the proposal

Re-entering line items after the client says yes wastes time and creates mismatches between what was agreed and what was billed.

The product

See the workspace your clients feel.

01

Proposals to paid invoices

Send quotes, bill milestones or retainers, and let automated reminders chase anything outstanding.

02

Every channel in one inbox

Email, SMS, calls, and voicemail land beside the client record — with AI summaries, so anyone on the team can reply with full context.

03

Client work, organized as projects

Tasks, files, and status for every engagement — visible to the team and, through the client portal, to the client.

04

A portal clients actually check

Clients watch progress, files, and invoices in a branded portal instead of asking your team for updates.

Workflow

How a freelance proposal moves in Workspace369

01

Build from your catalog

Add your services and prices once, then assemble each proposal from catalog line items with your branding and PDF layout.

02

Share one link to accept and sign

The client opens the proposal, reviews the scope and price, then accepts and signs it online. No client account is needed.

03

Follow up automatically

Email automations can remind a client who hasn't responded. Proposal engagement tracking, on every plan, shows how the client has interacted with it.

04

Convert it into an invoice

Turn the accepted proposal into an invoice with the same line items and share a payment link. Every plan can collect a deposit when the client accepts.

Finally feels calm

Bounced between three or four all-in-one tools and always ended up in a mess of tabs. This is the first one that feels calm. Set up my client projects in ten minutes.

Painless team rollout

Rolled it out to our eight-person team and adoption was painless — intuitive and polished. I'd love more integrations, but they keep shipping.

★★★★★
Hours back every week

Was juggling separate tools for notes, tasks, docs, and updates. Consolidating into one place has genuinely saved me hours each week. Support is responsive too.

FAQ

What to check before you pick proposal software

What is proposal software for freelancers?

Proposal software for freelancers lets you build a priced proposal from your services, send it as a link, and record the client's acceptance and signature online. In Workspace369 the accepted proposal also becomes the project and the invoice on the same client record.

Can clients sign a proposal online on the cheapest plan?

Yes. Public proposal approval and signing are included on every plan, starting with Cadet at $29/month. Clients don't need an account to accept and sign.

Can I take a deposit when the client accepts?

Cadet ($29/month) and every plan above it can collect the deposit when the client accepts, with Stripe connected. You can also send a separate deposit invoice with a payment link after the client signs.

Is a signed proposal the same as a contract?

A signed proposal records the scope, price and terms the client accepted. Whether that's enough depends on your work and location; many freelancers add their terms to the proposal. This isn't legal advice, so check anything high-stakes with a lawyer.

Does Workspace369 replace HoneyBook or Dubsado for proposals?

For many freelancers, yes: proposals, signing, projects and invoices sit on one client record. Test your own proposal and payment flow before switching, and re-create open proposals rather than assuming they transfer.
