CMMS vs. Spreadsheet: The Real Cost of “Free” Maintenance Tracking

The “free” spreadsheet myth

Starting maintenance tracking with a spreadsheet makes sense — you may already have Excel or Google Sheets, and your team knows how to update it. As equipment grows and PMs multiply, someone can end up spending hours every week just keeping the spreadsheet current. Whether that is happening in your shop is something you can measure.

An existing spreadsheet may add no license cost. That does not make the work around it free, and it does not mean software will eliminate that work. Let's separate what you spend today from what a different workflow might reduce.

Hidden cost #1: Admin hours — an example worth measuring

Someone has to maintain the spreadsheet. That person might be the maintenance lead, the plant manager, or the owner. They spend time on:

• Updating PM schedules when tasks are completed (or overdue)
• Cross-referencing due dates to figure out what's coming up this week
• Manually adjusting dates after a PM is completed late
• Tracking down techs to find out if a task was actually done
• Building reports for management or auditors
• Adding new equipment and building new schedule rows

Suppose your time log shows 5 hours a week maintaining the sheet and chasing information, and your loaded labor rate is $35/hour. These are example inputs, not industry averages. Over 52 weeks:

5 hours/week × 52 weeks × $35/hour = $9,100/year

At 8 hours/week, the same calculation is $14,560/year. That values the time currently used; it is not all recoverable savings. A CMMS still needs accurate records, schedule review, and follow-up. Measure how much of that work actually changes during a pilot.

Hidden cost #2: Missed PMs and breakdowns

A spreadsheet can highlight overdue dates, and reminders can be built around it. The question is whether your workflow reaches the person responsible. A PM can fall through the cracks because nobody checks the sheet on Friday, a filter hides a row, or a busy production week passes without anyone following up.

Imagine a belt failing on Tuesday after an inspection was missed. The missed inspection belongs in the investigation, but it does not prove the failure would have been prevented. Check the failure mode, the approved inspection method, and whether a defect could have been detected in time. Use the equipment manufacturer and site-approved maintenance intervals.

Build the event cost from your own records:

• Repair parts: Use the actual invoice and identify what a planned repair would still have required.
• Emergency service: Record the callout and labor charges actually incurred.
• Lost production: Agree the value with operations and finance; delayed output is not automatically lost sales.
• Freight and overtime: Count each incremental expense once, even if it appears in several reports.

Only the portion a changed workflow could reasonably avoid belongs in a savings scenario. If the evidence is missing, leave avoided breakdowns at zero and show that uncertainty. A reminder alone does not repair a belt or make the production window available.

Hidden cost #3: Emergency parts markup

When equipment fails unexpectedly, you may call the local distributor and pay for overnight delivery. Compare equivalent parts and delivered prices. Here are hypothetical quotes to show the calculation, not current supplier prices:

• A bearing quoted at $45 delivered on a planned order costs $120 plus $35 emergency shipping — $110 extra.
• A hydraulic hose assembly quoted at $85 delivered becomes $225 in an emergency — $140 extra.
• A replacement belt quoted at $30 delivered becomes $95 overnighted — $65 extra.

Pull your actual quotes and invoices before adding up the year. If an emergency premium is already included in a breakdown total, do not add it again here. Planned stock also has purchase and carrying costs; include any increase needed for the proposed workflow.

Hidden cost #4: Preparing usable maintenance records

When a customer or auditor asks about a repair, you need to retrieve the relevant record: when the work happened, who did it, what was found, and what action followed. Confirm the evidence and retention requirements that apply to your site with the person responsible for that review.

• Change history — Excel for Microsoft 365 has Show Changes, including who changed a cell and when. Check the controls and history available in your actual setup before comparing it with a CMMS.
• Incomplete records — A PM done but never logged leaves a gap in either system.
• Prep time — Track the hours spent finding and checking records. Keep these separate from admin hours already counted above.
• Findings — Record the actual cause and corrective work. Do not assign a generic certification-loss price or assume switching tools will prevent a finding.

A searchable work history can help you answer the question faster. Whether it meets a particular audit requirement depends on the records, controls, and procedures you use; neither a spreadsheet nor a CMMS guarantees that outcome.

The total: compare a specific scenario

Return to the maintenance lead spending 5 hours a week on admin. Suppose a pilot suggests the new workflow takes 3 hours. For illustration, hold that reduction for a full 52-week year at $35/hour, use a $49 monthly license, and allow 12 hours for setup and training:

• Time released: (5 − 3) × 52 × $35 = $3,640
• License, billed monthly: 12 × $49 = $588
• Setup and training time: 12 × $35 = $420
• Modeled first-year net value: $3,640 − $588 − $420 = $2,632

This example assumes no avoided breakdown, emergency-parts, or audit costs. It values released labor capacity; it is not $2,632 of cash saved unless paid costs actually fall. Shorten the benefit period if adoption takes time, include other implementation costs, and use the license price and features your team needs. If the hours do not fall, the same scenario has a $1,008 first-year cost and no modeled benefit.

What switching buys instead

A purpose-built CMMS gives the team a shared workflow. RunTight has a Free plan and paid options; compare the current features and limits with the work you need to do:

• Automatic PM reminders — The system can tell techs what is due. Someone still needs to act on reminders and review overdue work.
• Mobile work orders — Techs can record checklist results on their phone at the equipment. The work itself still takes the time its procedure requires.
• Parts tracking with reorder alerts — On a plan that includes these features, record stock and receive low-stock alerts. Accurate issues, receipts, and purchasing follow-up still matter.
• Reviewable records — Completed tasks can retain timestamps and user attribution. Use the available filters to retrieve records by equipment and date range, subject to your retention settings and procedures.
• Your whole team — No per-user fees: each plan is one flat price for the workspace, and plans differ in how many users they include. Count the people who need access before choosing a plan.

A useful business case connects these features to a measured change: fewer hours chasing updates, fewer duplicate entries, or an earlier purchasing decision. Keep projected benefits separate from results you have already observed.

The switching cost objection

Switching can feel like another project when the team is already busy. “We'll move to real software next quarter” becomes a permanent deferral.

Start with a manageable group of equipment. Check the asset list, pull the approved PM checklists from the OEM manuals or your existing process, and verify the schedules. Have a technician complete a real workflow and check the resulting record. Count the setup and training time in your comparison, as the example above does.

Give the pilot a review date. Compare the hours and record quality with the baseline before expanding it.

Making the case to your boss

If you need to justify the switch to an owner or plant manager, use their language — dollars:

1. Record current admin hours, then estimate the reduction a pilot supports: hours avoided/week × weeks in use × loaded hourly rate
2. Review the last 12 months of breakdowns. Identify which costs the proposed workflow could plausibly avoid, and record the evidence and uncertainty.
3. Compare planned and emergency parts invoices. Exclude premiums already counted in breakdown costs.
4. Record additional audit-preparation time without counting admin hours twice
5. Subtract the applicable license, setup, training, and additional ongoing costs. Show a case with no improvement as well as the expected case.

Bring the assumptions as well as the total. Your boss should be able to see what would have to change for the switch to pay off, and what you will measure to check it.
