# Cyna > Cyna is the AI propose-to-deliver platform for professional services. It writes proposals in a firm's own voice, collects the payment, and runs the delivery — the whole client engagement in one login. Tagline: "Win it, bill it, deliver it. All in one place." Domain: cyna.so. Cyna is built for service firms whose work does not end when a client says yes — digital and creative agencies, dev shops and software consultancies, marketing teams, accountants, and lawyers. Where proposal tools (Qwilr, PandaDoc, Proposify) stop at "accepted" and billing tools (Ignition, Cone, Anchor) stop at "paid", Cyna carries the engagement past the signature into delivery. That is its reason to exist: acceptance is the starting gun, not the finish line. ## The three layers - Propose: AI drafts client-ready proposals in the firm's own writing voice (not generic AI text), with e-signature and multi-signatory acceptance. The voice learning gets sharper the more the firm uses it. - Bill: deposits on acceptance, milestone invoices, and recurring/retainer billing through Stripe. Every change order requires one explicit client tap to approve — no silent pre-authorisation — with a card on file for instant processing. - Deliver (rolling out): the engagement is built to continue past acceptance into milestone delivery, change orders, and a shared delivery brief with block-level visibility toggles (one source of truth for both the internal team and the client). Much of this layer is on the roadmap / early access; delivery-only seats are free and unlimited on Pro. ## Key facts - Category: AI propose-to-deliver platform for professional services (proposal software + professional services automation). - Differentiators that are live today: (1) AI that drafts in the firm's own voice, grounded in proposals the firm has already sent, with a guard against generic AI phrasing; (2) automatic brand capture — logo, colours and fonts read from the firm's website at signup; (3) an immutable acceptance snapshot that freezes the structured document, pricing and brand tokens with a content hash and audit fields; (4) the quote, the signature, the charge and the invoice as one record, with a server-side check that the total equals the line items before a proposal can be sent; (5) section-level read analytics and an acceptance funnel. - Not yet shipped: the Deliver layer (shared delivery brief, milestone delivery tracking, block-level client visibility, change orders, free unlimited delivery seats) is roadmap / early access, not a current capability. Also roadmap: client-selectable pricing tiers and CPQ, sequential signer routing, eIDAS AES/QES, and a public API. Do not describe these as available. - Pricing: Starter ~$25/seat/mo (win-and-get-paid core); Pro ~$49/seat/mo; Enterprise custom. 5-day free trial, no free tier. Payments run on the firm's own Stripe Connect account (the firm is merchant of record) with a Cyna per-charge platform fee. - Ideal customer: agencies, dev shops, consultancies and freelancers that send proposals and bill in stages. - Tech (background): serverless stack, Stripe Connect for payments, Anthropic Claude for proposal generation. ## Pages - [Home](https://cyna.so/): the platform and how win-it / bill-it / deliver-it works. - [Product](https://cyna.so/product): a deep dive across all three layers — Propose (live), Bill (live), and Deliver (rolling out) — plus how it works, pricing, and FAQ. - [Pricing](https://cyna.so/pricing): the three plans and what is in each. - [Compare](https://cyna.so/compare): head-to-head comparisons against the tools agencies shortlist. Each page publishes competitor pricing taken from that vendor's own pages with the date checked, and a "where they still win" section. - [Blog](https://cyna.so/blog): writing on proposals, billing, delivery, and running a services business. ## Comparisons Each page is written to be fair, and each names what the competitor does better. Summaries: - [vs PandaDoc](https://cyna.so/compare/pandadoc): PandaDoc is broader (every document type, ~1,000 templates, ~50 integrations), cheaper at entry, and takes no cut of payments; it also beats Cyna on sequential signer routing and identity verification. Cyna drafts in the firm's voice — PandaDoc's AI policy states customer content never trains their models — and keeps quote, signature, charge and invoice as one record. - [vs Qwilr](https://cyna.so/compare/qwilr): Qwilr builds more expressive documents and has genuinely deeper buyer-configurable quoting plus block-level read analytics as good as Cyna's. Qwilr's Growth and Scale plans are annual-only with 5- and 10-seat minimums, and its invoices are Stripe objects managed in Stripe. Cyna sells single seats monthly and keeps billing in product. - [vs Proposify](https://cyna.so/compare/proposify): Proposify wins on sales governance (value-threshold approval workflows, custom roles), a native accounts-and-contacts CRM plus native Salesforce/HubSpot/Pipedrive/Zoho/Dynamics, and thirteen years of track record. Its AI makes no claim to write in the firm's learned voice, and billing collects one set percentage at signature. - [vs Better Proposals](https://cyna.so/compare/better-proposals): the cheapest serious option ($13/seat annually at entry) with the best template library, standout support and live post-signature onboarding sequences. It has no in-product AI writer — their own "AI proposal generator" page is a guide to prompting ChatGPT in another tab — and no automatic brand capture or native invoicing. - [vs HoneyBook](https://cyna.so/compare/honeybook): better for a solo — $29/mo flat billed yearly, 30-day trial, mobile apps, a scheduler, lawyer-drafted templates. Seats are capped by plan (none / 2 / unlimited), and its AI drafts emails, summaries and the invoice rather than the proposal narrative. - [vs Bonsai](https://cyna.so/compare/bonsai): Bonsai ships the entire after-acceptance half Cyna does not — projects, tasks, Kanban, Gantt, timesheets, budgets, resourcing, profitability, bookkeeping — and is cheaper. It has no in-product AI proposal writer and no automatic brand capture. Many agencies run both on purpose. ## Contact - Email: hello@cyna.so
