Technical debt is the accumulated cost of IT decisions that made sense at the time but now block growth, create security risk, or require specialist knowledge to maintain. Most SMBs have it in multiple forms. Most don't notice it until it costs them, an employee departure that reveals a system nobody else understands, an upgrade that takes six times longer than expected because of undocumented dependencies, or a security incident that exploited a gap that existed for years. Here are the six patterns we find most consistently in Northern BC and Alberta SMBs, and what to do about each.
What "Tech Debt" Means in Practice
Not all tech debt is the result of bad decisions. Most of it was the right choice at the time, an on-premises server installed in 2015 when cloud was expensive and unreliable, a manual report that was built before reporting tools existed. The problem is that the business has changed, the technology landscape has changed, and that original decision is now costing more to maintain than it would to replace.
Pattern 1: The One Big Server Doing Everything
A single on-premises server running file shares, a domain controller, a line-of-business application, and sometimes the accounting software. Painful to back up because every role has different dependencies. Impossible to upgrade because everything is tangled. When it fails, and it will fail, everything fails simultaneously.
How to pay it down: Split roles before you replace hardware. Move file storage to SharePoint/OneDrive. Move the line-of-business app to a hosted or cloud version. The domain controller can stay or migrate to Azure AD/Entra ID depending on your requirements. What you're left with is either a much simpler server or no server at all.
Pattern 2: Identity Sprawl
Every system has its own user database. The CRM has its own logins. The accounting software has its own logins. The project management tool has its own logins. When a staff member leaves, you need to remember to revoke access in each system individually, and you never do all of them on the first day.
How to pay it down: Microsoft 365's Entra ID as the primary identity provider, with SSO (SAML or OIDC) for every SaaS tool that supports it. When a user is disabled in Entra, their access to every federated tool is revoked simultaneously. Single off-boarding step. Dramatically reduced breach surface.
Pattern 3: Shadow IT
Individual departments signed up for SaaS tools without IT involvement. Marketing is on Mailchimp. Operations is on Notion. Support is on a helpdesk tool you didn't know about. None of it is in your SSO. None of it is in your security tooling. When a staff member leaves, you don't know what they had access to.
How to pay it down: First, inventory it without making it political, just find out what exists. Use a tool like Entra's cloud app discovery to see what services are authenticating with company credentials. Federate identity for tools you decide to keep. Consolidate where there's overlap. Document what you decide to run as intentional shadow IT with understood risk.
Pattern 4: Manual Handoffs
New hire provisioning takes multiple days because it requires email threads to HR, IT, and each department head. Offboarding is inconsistent because the steps live in someone's memory. Monthly reports are assembled manually from four different spreadsheets.
How to pay it down: Identity-driven provisioning (when a user is created in M365 with a specific role, group memberships and application access are provisioned automatically). Off-boarding playbook as a checklist, not a memory exercise. Report automation using Power BI, scheduled exports, or whatever tool your team will actually use.
Pattern 5: "It Only Works Because Bob Knows It"
A system, process, or configuration that only one person understands. When Bob is on vacation, things break in ways nobody can fix. When Bob leaves, the system becomes a black box.
How to pay it down: Document it before Bob leaves. Have Bob write the runbook while he still works there. Then evaluate whether the system should be automated, replaced, or simplified. The documentation exercise usually reveals that the reason it's complicated is historical, the complexity can be removed.
Pattern 6: Outdated Security Baseline
Systems running end-of-life operating systems. No MFA. Antivirus instead of EDR. The security configuration hasn't been updated since the business first set up IT. This isn't the result of a decision, it's the result of no decision.
How to pay it down: Run an audit. Document what you actually have. Prioritise by risk, end-of-life OS on an internet-facing system is more urgent than outdated firmware on an internal printer. Build a 12-month remediation roadmap and work through it systematically.
How to Build the Paydown Plan
Addressing tech debt all at once is overwhelming and expensive. Build a prioritised roadmap:
- Security baseline first, close vulnerabilities before doing anything else
- Identity and off-boarding second, the highest-leverage operational improvement
- Biggest single-point-of-failure third, usually the one big server
- Everything else in order of business impact
Each item should have an estimated cost, a risk-reduction benefit, and a proposed timeline. Review the roadmap quarterly.
