White-label branding for accounting firms
A practical product capability for Canadian accounting and bookkeeping practices.

SpidNums is white-label practice management: each firm runs the platform under its own name, logo, colours, tagline, letterhead and email display name, on its own domain or an instant spidnums.app subdomain. Clients see the firm's brand at every touchpoint — portal, engagement letters and email — and firms that want to resell under their own brand are invited to talk to us.
Your name, logo and colours everywhere
Branded emails and letterhead
Reseller-ready multi-tenant platform
Why your client software should carry your name
Clients hired the firm, not the firm's vendors. Every portal sign-in and system email is a brand impression, and when those carry a software company's logo, the firm's own identity is diluted at exactly the moments clients pay attention.
For firms with ambitions beyond their own book — multi-office practices, consultants who want to package a client system, firms building an offering for other firms — the question is sharper: can the platform disappear behind your brand entirely?
How white-label branding works in SpidNums
Branding is configured per firm: business name, logo, colour scheme, tagline, letterhead, and the display name on outgoing email. Those settings flow through the client portal, engagement-letter emails and signing pages, and the branded HTML email template.
The address completes the picture: the platform runs on the firm's own custom domain, or on an instant subdomain such as yourfirm.spidnums.app while a domain is being arranged.
Can you resell SpidNums under your own brand?
Yes — the platform is multi-tenant by design and reselling is invited. Each tenant is isolated behind a signed tenant cookie that fails closed, with file storage namespaced per tenant, and super-admin tooling covers tenant management, plan limits and audited impersonation for support.
Firms interested in running SpidNums as their own offering can talk to us about white-label terms.
What changes for the firm
Every client touchpoint — invite, engagement letter, portal, email — reads as the firm. There is no moment where a client meets an unfamiliar third-party brand, and a firm that resells presents a complete client system as its own.

Frequently asked questions
What exactly can we brand?
Business name, logo, colours, tagline, letterhead and the display name on outgoing email — configured per firm. The branding applies across the client portal, engagement-letter emails and signing pages, and the HTML email template, and the platform runs on your own domain or a yourfirm.spidnums.app subdomain.
Is white-label a higher pricing tier?
No. SpidNums has one plan — USD $1,200 per firm per year with everything included — and white-label branding is part of it. There is no separate enterprise tier to unlock your own logo, colours or domain.
Do system emails show our firm's name?
Yes. The email display name is part of each firm's branding, and messages use the firm's branded HTML template. Email sends through the firm's configured transport — Gmail SMTP or Resend — with a delivery log and a test send to confirm the setup before clients see it.
How is our data kept separate from other firms on the platform?
Isolation is per tenant and fail-closed: a signed tenant cookie scopes every request to exactly one firm, requests that cannot be attributed to a tenant are refused, and file storage is namespaced per tenant. Super-admin support access exists but impersonation is audited.
