Separate vendors can each be excellent and still fail you at the boundaries. This guide compares a single accountable team with a multi-vendor setup on the work that falls between them.
| Situation | Separate IT, web and dev vendors | One team (MSP + web + apps) |
|---|---|---|
| DNS / domain change | Agency asks IT, IT asks registrar — days of back-and-forth | Same team owns domains, DNS and the site |
| Contact form stops delivering | Web says “email issue”, IT says “website issue” | One team checks form, SMTP and Microsoft 365 together |
| Security incident | Three vendors, three partial views | One view across endpoints, identity, site and app |
| New app needs login + data | Developer must learn your identity and hosting | Built on the Microsoft 365 / Azure you already run |
| Accountability | Split contracts, split SLAs | One contract, one escalation path |
Where multi-vendor setups break
Problems rarely sit neatly inside one vendor’s scope. Email authentication (SPF, DKIM, DMARC), SSL certificates, hosting, backups and access rights touch IT, the website and custom apps at once. Every handoff adds delay and a place for ownership to disappear.
When separate vendors still make sense
If you need a highly specialized creative agency or a large product team, keep them — and make sure your IT provider owns domains, identity and security so the specialists plug into a stable base.

Frequently asked questions
- Does one vendor mean less specialization?
- Not necessarily. The benefit is shared context and accountability; specialists still do the work, inside one team and one contract.
- Can we keep our existing website agency?
- Yes. We can own IT, domains and security while your agency keeps design — or take over the site when you are ready.
- Do you work with US businesses?
- Yes. Delivery is remote-first across Canada and the United States.
