You've put real work into your brand. The logo, the colors, the whole presentation. And then your proposal lands in a client's inbox with a button that doesn’t lead to your company’s domain.
That's the gap a custom domain closes.
Instead of a Better Proposals link, your client gets something like proposal.yourdomain.com. One small detail, and your document immediately looks like it belongs to the same company that's about to do excellent work for them.
Clients form an impression before they read a single word. The link they click, the page that loads, the name in the address bar; all of it runs before your headline does.
A branded domain signals that you're not someone who just signed up for a free trial and sent a template. It signals a business that has its presentation sorted.
That's not a small thing. Especially at the proposal stage, when the client is still deciding whether you're the right choice.
There's a small setup detail that trips people up: you can't use your main domain.
Your main website already uses that; there's nowhere to redirect proposals without breaking something. What you need is a subdomain. Think of it as a dedicated section you create specifically for proposals:
Main domain: yourdomain.com
Custom domain for proposals: proposal.yourdomain.com
The "proposal" part is just a suggestion. Pick whatever fits your brand.
Choose your subdomain: proposal.yourdomain.com is the standard choice, but anything works
Add a CNAME record to your DNS settings: your hosting provider will have a guide for this; depending on your TTL, it may take a little time to propagate
Verify in Better Proposals: once the status goes green in your brand settings, you're done
One heads-up: some hosting providers will ask you to enter just the proposal part rather than the full subdomain. They add the rest automatically.
Every proposal you send from that point on looks like it came from your business, not a third-party tool you happened to use. Clients click a link that carries your name, land on a page that matches your brand, and start reading before any doubts have had a chance to form.
It's a quick setup. The payoff is that a customized domain makes your proposals feel polished, professional, and fully on-brand.
