Quotes, proposals & invoices for independent studios

Seal the deal.

Quotes, proposals and invoices that look expensive, sent as a live branded link. Your client toggles what they want and presses the seal. The invoice sends itself.

How it works

One flow, four moments

Open with a quick quote or a full proposal: separate documents, same flow. The moment your client seals one, the invoice writes itself.

  1. 01

    Quote or proposal

    Open fast with itemised pricing, or send the full pitch, investment and all. Two doors into the same flow.

  2. Sealed

    Your client picks their add-ons and presses the seal: a timestamped, audited yes.

  3. 03

    Invoice

    Writes itself the moment they seal, from exactly the scope they agreed to.

  4. 04

    Paid

    Straight into your own account, through your bank or your own Stripe. Sealbase never processes the payment.

The seal does the paperwork. The invoice is written from exactly what was agreed.

This is what your client sees

Don't take our word for it. Press the seal.

A live miniature of the client experience. Toggle the add-ons, watch the total move, then seal it yourself.

What makes it Sealbase

One tool, from first draft to signed invoice

Beautiful where it's seen, honest where it counts. Every feature exists to shorten the distance between the pitch and a signed invoice.

Sealing

Seal-to-accept

Accepting stamps a wax seal onto the document: a timestamped, audited signature that records who sealed, when, and exactly what scope they agreed to. The one signing moment that actually feels good.

Proposals

Web-first documents

Every quote, proposal and invoice is a hosted, branded link, live and interactive, never an attachment. Quotes and invoices also export as a pixel-identical PDF; a proposal stays a live page, because that's the whole point of it.

Builder

Blocks, not blank pages

Every document is composed from typed blocks (cover, overview, pricing, terms), pre-structured per type, so it always comes out looking considered. Saved templates come next.

Pricing

Interactive pricing

Clients toggle optional add-ons and watch the total update live. Self-selection quietly lifts the deal size.

Getting paid

Paid straight to your account

Add your bank details for EFT, or connect your own Stripe account so clients can pay you by card through Stripe. Sealbase never processes or touches the payment: the money settles straight into your own account, and we never take a cut.

Branding

Your brand, your domain

Your business name and details on every document you send, with your own colours, type and domain on the way, so the link lives on your site, not ours. It feels like your document, never “made with a tool”.

The old way

  • A PDF attached to an email, opened once, maybe
  • “Just checking you got my quote?” follow-ups
  • Scope agreed in a reply, then retyped into an invoice
  • Weeks of silence between the yes and the money

The sealed way

  • A branded web page at a link you send, never an attachment
  • A live status from sent to sealed to paid, no chasing blind
  • Optional add-ons your client says yes to themselves
  • The invoice writes itself the second they seal
“We built Sealbase because every proposal we sent as a PDF died in an inbox. The documents that win the work deserve better than an attachment.”

Fair questions

Asked before every first send

Sealbase hosts money documents, so the answers here are deliberately unexciting.
