TL;DR
- A PCB manufacturer with 22 years of accumulated technical debt needed a full technology audit before an ownership transition could close
- We found 4 vendor accounts only accessible through a former employee's personal password manager, 3 undocumented servers still running production workloads, and $420/month in unused SaaS subscriptions
- We recovered access, decommissioned dead systems, corrected a broken Azure migration, and produced a complete handoff package for the incoming ownership team
- Audit complete in six weeks; deal closed with no IT due-diligence issues; $420/month in cancelled subscriptions covered ~40% of engagement cost
22 Years of Accumulated Technical Debt
A PCB contract manufacturer had been in operation for 22 years. The technology environment had accumulated accordingly: servers added and never fully decommissioned, a partial cloud migration that stopped halfway, software licenses under former employees' email addresses, recurring charges on credit cards that had since been canceled — failing silently — and a network that one longtime IT contractor understood and nobody else did.
The ownership transition was planned. The buyer's attorney flagged IT due diligence as a required item before close.
What the audit found:
- 14 active vendor accounts, of which 4 were accessible only through credentials stored in a former employee's personal password manager
- 3 servers in a rack that were running but had no documented purpose — one turned out to still be serving a legacy ERP module that had been "replaced" three years prior
- A domain registrar account registered under a personal email address with no secondary contact
- $1,840/month in recurring SaaS charges, of which approximately $420/month were for tools no one was actively using
- SSL certificates on two public-facing services expiring within 60 days, unmonitored
- A partial Azure migration that had moved some file shares to cloud storage but left directory sync in a broken state affecting login behavior at one workstation group
The core risk for the buyer: undocumented systems, inaccessible accounts, and technical obligations (expiring certificates, failing payment methods) that would become the incoming ownership team's problem on day one.
Audit, Remediation, and Handoff Package in Six Weeks
We worked in parallel streams over six weeks.
Access recovery and documentation: Recovered access to all vendor accounts, transferred ownership to business email addresses under company control, and documented every account in a structured asset register — vendor contact, renewal dates, contract terms, and assigned internal owner for each entry.
Environment cleanup: Decommissioned the three undocumented servers after verifying no active dependencies (the legacy ERP module was exported and archived). Cancelled $420/month in unused subscriptions after confirming no active use with the operations team. Renewed the two expiring SSL certificates and configured automated monitoring so future expirations would be flagged 60 days out.
Azure migration remediation: Identified the root cause of the directory sync issue — a misconfigured sync rule introduced during the original migration — and corrected it. Completed the remaining file share migrations that had been left pending, bringing the Azure environment into a consistent, documented state.
Handoff package: Produced a complete technology transfer document for the incoming ownership team: network diagram, server and services inventory, vendor register, active subscription summary, open items requiring attention within 90 days, and recommended actions within the first year.
Deal Closed, No IT Due-Diligence Issues
The technology audit and remediation were completed six weeks from engagement start, ahead of the deal timeline.
The buyer's IT due diligence review found no unresolved issues.
- Deal closed on schedule — IT due diligence cleared with no outstanding issues
- Incoming ownership team had documented access to every system from day one — no dependency on institutional knowledge from departing staff
- $420/month in cancelled subscriptions — approximately $5,040 annually, covering roughly 40% of the engagement cost within the first year
- Azure environment stabilized — directory sync corrected, remaining file migrations completed, cloud environment in a documented, consistent state
- SSL certificates renewed and monitored — no expiration surprises in the 12 months following handoff
The incoming ownership team inherited a documented, cleaned-up environment rather than a black box. That's a different starting position than what most ownership transitions produce.
Frequently Asked Questions
What is IT due diligence in a business acquisition? IT due diligence is a review of the technology environment that's part of the overall business acquisition process. The buyer's team (or attorney) wants to understand what they're taking on: vendor contracts, access credentials, recurring costs, technical liabilities like expiring certificates or unsupported software, and any systems that are undocumented or inaccessible. An IT audit surfaces these issues before close, so they can be addressed, negotiated, or priced into the deal.
What happens when vendor accounts are registered under a former employee's personal email? It depends on the vendor. Some will verify business ownership and transfer the account with proper documentation. Others require the original account holder to initiate the transfer. In either case, the process takes time and cooperation that can't always be assumed. The risk during a transition: if the account isn't transferred before the employee leaves (or has already left), you may lose access to billing history, contractual documentation, or the service itself until the transfer is resolved.
How long does a technology audit take for a manufacturing company? For a mid-sized manufacturer with 10–20 vendor accounts and a mixed on-premise/cloud environment, four to eight weeks is typical. The timeline depends heavily on how accessible vendor accounts are and how much remediation work surfaces. This engagement completed in six weeks because the ownership timeline gave everyone a forcing function.
What should the outgoing owner provide to make the transition smooth? At minimum: a list of every vendor account and the login credentials or recovery email; a list of every recurring charge and which card or bank account it's billed to; access to any physical hardware (servers, networking equipment) the buyer is inheriting; and the name of any third-party contractor who has access or institutional knowledge. The less of this that's documented before the engagement, the more recovery work is involved.
Why was $420/month in unused subscriptions still being charged? The most common reason: the tools were set up for a specific project or employee, the project ended or the employee left, and no one reviewed the subscription list afterward. Recurring SaaS charges that fail silently (because the card expired) show up in vendor account dashboards but not in bank statements. A full vendor account review — not just a bank statement review — is the only way to catch them all.
