White-label CRM on your own domain: what’s possible, and what to check

“White-label CRM on your own domain” can mean three different things: the login lives on a domain you own (app.youragency.com), the login lives on a branded subdomain of the vendor’s domain (youragency.vendor.com), or only your client-facing websites and funnels live on your domain. Platforms differ on which of these they offer and at what tier, so ask before you buy. This guide explains the difference, says plainly what Stack Space does today, and covers the step that matters more than any URL: authenticating the email your clients send.

All competitor prices are as of July 2026 from the vendors’ own pricing pages and public reports; they reprice often, so confirm before you budget.

What does “white-label” actually mean in practice?

A properly white-labeled CRM has four layers, and plenty of platforms hand you only one or two.

1. The brand skin. Your logo in the header, your colors, your favicon in the browser tab, your brand name in the UI. If your client can find the vendor’s name all over the product, that’s co-branding, not white-label.
2. The address. Where your clients type to log in. This ranges from a domain you own, to a branded subdomain of the vendor’s domain, to a generic vendor URL. It’s the most visible layer and the one with the widest spread between platforms.
3. Client isolation. Each client gets their own sub-account: their own contacts, pipelines, calendars, and conversations, invisible to your other clients. You switch between them from one login; they only ever see theirs.
4. Your billing. Clients pay you, on your Stripe, at a retail price you set. You pay the platform wholesale and keep the spread. Skip this layer and you’re a referrer, not a software company.

Get all four in some form and something changes: you stop being “the agency that uses some CRM” and become “the agency with its own platform.” That’s stickier revenue and higher perceived value.

Which platforms put the CRM login on your own domain?

Some do, some don’t, and some only do it on their top tier. In general you’ll meet three setups:

• Custom login domain. You add a DNS record (usually a CNAME) pointing something like app.youragency.com at the vendor, and the vendor serves the app and its SSL certificate on your hostname. This is the most convincing version, and it tends to sit on higher-priced agency plans.
• Branded subdomain on the vendor’s domain. Your clients log in at youragency.vendor.com. The brand inside the app is yours; the address bar still carries the vendor’s domain.
• Your domain for client-facing pages only. Websites, funnels, and booking pages run on your domain or your client’s domain, while the CRM login stays on the vendor’s.

Many platforms combine the last two. Before you sign, ask the vendor four questions:

1. Can my clients’ login page run on a domain I own, or only my websites and funnels?
2. Which plan tier does that require?
3. Do password reset and invite emails link to my domain or theirs?
4. Who provisions and renews the SSL certificate?

Get the answers in writing. “Custom domain” on a feature list often means websites, not the CRM.

What does Stack Space do today?

Being straight about our own product, since this is our blog:

• Your login is a branded subdomain of ours. From the Professional plan ($355/mo), you claim a subdomain on the White-label page, and your clients log in at youragency.stackspacesolutions.com. The CRM login does not run on your own domain today, so the address bar carries our domain while everything inside is your brand.
• The brand inside is yours. Brand name, logo, brand colour, favicon, your support email, and a switch to hide platform branding. It applies across your agency workspace and every client sub-account.
• Your websites and funnels can run on your own domain. Sites and funnels you build for yourself or for clients connect to a custom domain (youragency.com, joesplumbing.com, www. or bare), with the DNS records shown in the dashboard.
• Billing runs on your Stripe. You set the retail plan per client and keep the spread; client usage is billed to you at posted wholesale rates, with no per-sub-account base fee. The Agency plan ($800/mo) scales the same setup for a full client book.

If a login on your own domain is a hard requirement for your clients, choose a platform that offers it at the tier you can afford. If your clients mostly meet your brand through their website, funnels, booking pages, and the app itself, a branded subdomain is usually enough.

How do you set up white-label in Stack Space? (step by step)

Step 1: Set your brand

On the White-label page, set your brand name, logo, favicon, brand colour, and support email, and decide whether to hide platform branding. Ten minutes, no code.

Step 2: Claim your subdomain

On the same page, pick your label (youragency). It becomes youragency.stackspacesolutions.com, and it’s unique across the platform, so claim it early. There’s no DNS step for the login.

Step 3: Connect your own domain to your websites and funnels

This is where your domain does its work. In Sites or Funnels, open a site’s domain settings, enter your domain or your client’s, and add the records the dashboard shows at your DNS provider (Cloudflare, GoDaddy, Namecheap, anywhere). Propagation usually takes minutes, occasionally a few hours.

Step 4: Create client sub-accounts

Each client gets a sub-account: their contacts, pipeline, inbox, booking calendar, invoices, and automations, walled off from every other client. You switch between sub-accounts in one click from your agency view.

Step 5: Invite clients and set your price

Invite your client’s team to their sub-account; they log in at your branded subdomain and see your brand. Connect your own Stripe, set your retail price per client, and Stack Space handles the subscription billing in-app. You keep whatever margin you set.

Realistic time estimate: an afternoon, most of it spent on your own account and on DNS for your websites.

What do your clients see vs. what you see?

That last row matters more than any other. More on it below.

What are the pitfalls nobody warns you about?

Go in clear-eyed. These are the four places first-time white-labelers get burned.

1. Your app domain is not your email sending domain

This is the big one, and it applies whichever login setup you choose. Branding the app does not authenticate the email your clients send. Every client sending campaigns needs their own sending domain with SPF, DKIM, and DMARC records, ideally on a subdomain of the client’s domain (mail.clientbusiness.com), never pooled on yours.

Why so insistent? Because shared sending infrastructure is how things go wrong at scale. One bad sender on a pooled domain drags down everyone sharing it, and operators who pool their clients on one sending reputation have watched a single bad list tank inbox placement for the whole group. One client’s bad list should never be able to torch another client’s deliverability, or yours. Treat app branding and email authentication as two separate projects, because they are.

In Stack Space, the deliverability settings check each sending domain’s SPF and DMARC records against live DNS and confirm DKIM where they can detect it. DKIM selectors vary by email provider, so a DKIM record we can’t find shows as unknown rather than failed. Whatever platform you use, check all three before a client’s first campaign.

2. Your brand on the login screen means your name on the support ticket

When the software is “yours,” clients call you when they forget a password or an automation misfires. Budget for tier-1 support: a shared inbox, a short FAQ doc per client, and upfront onboarding (“here’s what to do if…”). The platform backs you up behind the scenes, but the client-facing layer is now part of your product. Price your retail accordingly. This is also why you can charge a real margin.

3. Don’t resell what you haven’t run

Run your own agency on the platform for a few weeks before you put a client on it. You’ll find the rough edges on your own account instead of on a paying client’s, and you’ll onboard clients twice as fast because you actually know the product.

4. Check what tier white-labeling actually requires

Platforms bury this. On GoHighLevel, rebilling requires the $297/mo plan and markup rebilling (SaaS mode) requires $497/mo, before usage fees, which can add meaningfully to the sticker. Vendasta runs $99–$999/mo with 12-month commitments on its Professional and Premium plans, and its white-label client portal — your logo, Business App renamed, Vendasta branding removed — starts on Professional, not at the top: Starter is co-branded with Vendasta, and the $999 Premium tier adds the multi-location client portal (gohighlevel.com and vendasta.com/pricing, October 2026); third-party pricing write-ups also report setup packages of $500–$2,500 on those plans, though Vendasta’s own page says onboarding is included (revenuegeeks.com, July 2026). HubSpot doesn’t offer white-labeling at all. None of these are scams; GHL’s SaaS mode is genuinely mature and its snapshot system is excellent. Read the tier fine print, including which tier puts the login on your own domain, before you promise a client their branded portal. Stack Space includes white-label branding on a branded subdomain, sub-accounts, and reseller billing on your own Stripe from the Professional plan ($355/mo), and the Agency plan ($800/mo) scales it for a full client book, with no per-sub-account base fee, AI included, and client usage billed at posted wholesale rates you can mark up.

What should you charge clients for a white-labeled CRM?

Short answer: anchor to what it replaces, not what it costs you. A local business paying separately for a CRM, texting, booking, review requests, and invoicing is commonly spending several hundred dollars a month across tools. If an AI receptionist replaces a $250–$1,725/mo (ruby.com/plans-and-pricing, October 2026) human answering service (the going rate), your bundle at $300–$500/mo is an easy yes. Agencies reselling platforms this way typically price per sub-account at 2–4× their wholesale cost. Set your price; it’s your Stripe. What we won’t do is promise you revenue. Your margin depends entirely on your offer and your market.

FAQ

Can my clients log in to Stack Space at app.youragency.com? Not today. Your clients log in at a branded subdomain of ours, such as youragency.stackspacesolutions.com, with your brand name, logo, colour, and favicon inside. Your own domain connects to the websites and funnels you build, not to the CRM login.

Do I need to buy a domain for white-label? Not for the login: your branded subdomain needs no DNS. You’ll want a domain you own for your agency website and funnels, and each client will want theirs for their site and their email sending.

Will my clients know it’s not my software? Not from the product itself: the logo, colors, name, and support email are yours. On Stack Space the login URL carries our domain, so a client who reads the address bar can see it. White-label means the brand is yours, not that you built it. If a client asks directly, “we run our platform on a specialist provider’s infrastructure” is true and lands fine.

Can clients pay me directly instead of the platform? Yes, that’s the point of reseller billing. In Stack Space you connect your own Stripe, set your retail price per sub-account, and client subscriptions run through you. You keep the difference between retail and wholesale.

Does white-labeling the app fix my email deliverability? No, and be suspicious of anyone who implies it does. App branding and email authentication are separate. Each client needs their own sending domain with SPF, DKIM, and DMARC, and you want a platform that checks those records and shows you delivery metrics per client instead of pooling everyone’s reputation.

How long does setup take? Brand settings and your subdomain take about ten minutes. Connecting a custom domain to a website or funnel takes a few minutes plus DNS propagation, usually under an hour. Realistically you’ll spend most of your first afternoon setting up your own account properly so client onboarding goes smoothly.

Stack Space is built to be resold: white-label branding on a branded subdomain, isolated sub-accounts, and billing on your own Stripe, with Stax, the AI brain, training and managing the 17 AI employees inside every client account you spin up. White-labeling is one pillar of the resell model. The others are what you’re actually selling: read how agencies package the platform as their own SaaS, how to land your first 5 agency clients, and what local businesses want in an all-in-one platform so your retail offer writes itself.
