Northbound Brand Co.

Every proposal above was generated from a two-line brief. None of them were designed by hand — and replying first wins 5–10× more deals.

The loop

From brief to signed to paid.

Brief in. Forward an email, paste a Slack thread, drop in a PDF. Wintura extracts scope, timeline, and budget signals.

Draft out. Every section written in your voice, on your brand, with your rates already applied.

Edit & lock. Adjust any section like a document. Lock pricing and scope so nothing drifts after you send.

Send & sign. One magic link. No password for the client. Signed inline on any device, no third party.

Invoice & collect. A won proposal becomes an invoice in one click, with the payment ladder already staged.

Under the hood

Details worth getting right.

Brand auto-fill. Logo, colours, rates and terms load the moment a brief lands. No hunting for last quarter’s template.

Service detection. Wintura reads what you sell and picks the section structure that fits it — a build, a retainer, an installation.

Voice learning. Each proposal you edit teaches it how you write. The next draft sounds more like you than the last.

The SOW cannot drift. Proposal and SOW render from one agreement, so a deliverable can never appear in one and not the other.

Read tracking. See what the client opened, which sections they lingered on, and how long — so you know who to chase.

Win/loss analytics. Close rate by service and pricing trends across everything you have sent.

One engine. Your client's ink.

Every proposal renders in the client's own brand colour — this is the only surface on the page where that colour is not ours to choose. Pick a client, or set your own.

Frequently asked questions

Your proposal tool, e-signature app, invoicing app, and the spreadsheet you track pipeline in. One platform for the full cycle: brief to paid invoice.

Yes — all sections, in your voice, with your rates. You edit what you want and send. Most drafts need a few minutes of adjustment, not a rewrite.

It learns from every proposal you edit and grounds each draft in your own site, services and past work. The first one sounds like you; the tenth sounds more like you.

Four to eight hours becomes about ninety seconds, and the scope is written down and signed before work starts.

Yes. A won proposal converts to an invoice in one click, with the payment schedule already staged. Clients pay by card or bank transfer, direct to your account.

That is the core case. Deposit, midpoint and launch milestones are the default billing shape, not an afterthought.

The proposal moves to lost with the reason recorded, and win/loss analytics shows which services and price points you lose on.
