Why budget from age and warranty
Devices rarely fail on a convenient schedule, but they do age predictably. A refresh budget turns that into a plan: which devices are due, in which year, and what it will cost, so replacement is a decision made in advance, not an emergency.
Step 1: get the inventory right
A forecast is only as good as the register behind it. You need every device, its type and, ideally, when it was bought. Purchase dates come from invoices, Apple’s order records, or the date a device first appeared in your MDM. Where nothing else exists, an enrolment date is a reasonable stand-in.
Step 2: set a replacement policy for each device type
Decide, per type, how old a device can be before it’s replaced, how much warranty grace you allow, and what a replacement costs. A laptop policy and a desktop policy will differ, and some types, such as printers or phones, you may choose not to forecast at all.
- An age limit, such as four years for laptops.
- A warranty rule: replace when the warranty ends, or allow a grace period.
- A replacement cost for each type.
Step 3: group by when it’s due
Sort devices into overdue, due within a year, due in one to two years and two to three years. Each group gets a device count and a cost.
As an illustration with round, made-up numbers: 40 laptops at £900 each, of which 4 are overdue, 10 are due within a year and 12 in the year after, gives £3,600 overdue, £9,000 next year and £10,800 the year after. That’s the conversation a finance director wants to have.
Step 4: treat operating system end of support separately
A device that can’t run a supported operating system is a replacement reason, but a device that can be upgraded for free isn’t a cost. Show operating system end of support alongside each device without counting free upgrades as replacements, so the budget isn’t inflated.
Step 5: present it
Take the forecast to finance, or into the client meeting, as one page: the devices that are overdue, what’s due in each year and the cost. Keep the assumptions visible so the numbers can be challenged, and revisit it as devices are replaced or bought.
Automating the forecast
Omnia Manage gives every device a replacement date from its age and warranty, priced from the policy you set for each device type. Warranty dates come from your RMM where it has them, otherwise they’re estimated from the purchase or enrolment date, and each date shows where it came from. The forecast is grouped by year and appears in each client’s IT review.
