To budget for mobile devices and services, build the budget from your device list rather than last year’s invoice total. Give planned refresh, unplanned replacement, wireless plans and the services that keep devices working their own lines. Then add a currency assumption for devices priced in US dollars and a contingency sized to how old the fleet is.
If you’re the finance lead signing off next year’s mobility budget, this guide gives you the lines a complete budget needs, how to forecast each one, the costs that usually push mobility over, and the questions to put to IT before you approve the number.
Key takeaways
- A mobility budget built from last year’s actuals misses the lines that cause overruns. Start from the device list, with one row per model and its support end date.
- Unplanned replacement deserves its own budget line. Lost, broken and failed devices happen every year, and the cost rises with fleet age.
- Security update end dates drive the refresh forecast. A model that loses support mid-year forces an unplanned refresh if you haven’t budgeted for it.
- Wireless plan costs need an audit before they’re budgeted. Unused lines and old plans carried into next year inflate the baseline.
- The services around the hardware are part of the mobility budget. Staging, device management, repair and secure retirement cost money whether they’re bought or done in-house.
What a mobile device and services budget should include
A complete mobile device and services budget has eight lines, and each one has a different driver and a different owner. Most overruns come from lines that were never in the budget, which is why a single “mobility” line can’t explain next year’s variance. The table below shows each line, what drives it and where the number should come from.
| Budget line | What drives it | Where the number comes from | Usual owner |
|---|---|---|---|
| Planned refresh | Models reaching end of security support or end of useful life | Device list with support end dates and current quotes | IT with procurement |
| Unplanned replacement | Loss, breakage and failure | Last 12 to 24 months of replacements by model | IT |
| Accessories and spares | Batteries, chargers, cases, mounts and spare devices | Accessory spend history and spare pool size | IT or operations |
| Wireless plans | Active lines, plan types and usage | Audited carrier invoices, not last year’s total | IT, finance or procurement |
| Staging and deployment | New devices and replacements to set up | Device count times setup cost, or IT hours | IT |
| Device management (MDM) | Licences and the people who run the platform | Licence count and admin time or service fee | IT |
| Repair | Out-of-warranty failures and shipping | Repair invoices by model, plus warranty end dates | IT |
| Retirement and data destruction | Devices leaving the fleet | Number of devices retired times per-device cost | IT with security |
How to forecast a device refresh
Device refresh is the biggest and most predictable mobility cost, as long as you forecast it from model support dates instead of device age alone. Three steps get you a refresh number you can defend.
Start the refresh forecast from the device list and support end dates
A refresh forecast starts with one row per model, the number of units in service, and the date each model stops receiving security updates. Manufacturers in Google’s Android Enterprise Recommended program must publish the security update support end date for their validated devices, so IT can usually find this date for Android models on the manufacturer’s website.
Any model whose support ends within the next year or two belongs in the refresh line. Devices that lose security updates become a compliance and security problem, and replacing them in a hurry costs more than replacing them on a plan. Read more on what to do when devices age out of security updates.
Spread device refresh across years instead of one spike
A whole-fleet refresh every four or five years creates a budget spike that’s hard to approve and hard to execute. A rolling refresh replaces a share of the fleet each year, oldest models first, so the refresh line stays roughly level.
Just know that a rolling refresh means running more than one model at a time. That’s manageable when devices are staged to the same standard, but it adds work if every model is set up by hand.
Budget a currency assumption for devices priced in US dollars
Many enterprise mobile devices and accessories are priced in US dollars, so the Canadian-dollar cost of a refresh moves with the exchange rate. The Bank of Canada publishes daily exchange rates each business day.
Pick the rate your finance team uses for planning, state it in the budget, and ask procurement whether quotes are fixed in Canadian dollars or will be converted at order time. That one assumption explains a lot of refresh variance later.
How to forecast wireless plan costs
Wireless plan costs should be forecast from an audited list of active lines, not from last year’s carrier total. Last year’s total includes lines nobody uses and plans nobody reviewed, and carrying it forward builds that waste into next year.
Audit wireless lines before you budget them
An audit matches every active line on the carrier invoice to a person, device or role. Lines with no user, no usage or a plan that no longer fits get cancelled or changed before the budget is set.
Here’s what actually happens when this step is skipped. Lines for former staff and retired devices keep billing quietly, and the budget treats them as a fixed cost. See how a wireless audit works and what the first report shows.
Wireless prices also move during the year. Statistics Canada reported that cellular service prices rose 1.5% year over year in February 2026, after a 4.9% rise in January, with a monthly decline driven by lower-priced plans. Consumer price data isn’t your enterprise contract rate, but it shows why plan costs need a review each year.
Plan wireless costs for headcount changes and seasonal staff
Wireless costs follow headcount, so the wireless forecast should use the same hiring plan as the rest of the budget. If you add seasonal workers in retail, logistics or healthcare, budget the lines and devices for the peak months and the work to suspend or cancel them afterwards.
The hidden costs that push mobility budgets over
Mobility budgets usually go over because of costs that sit in other budgets or in nobody’s budget. Five are worth naming in next year’s plan, even if they’re estimated.
Downtime. A worker without a working device stops scanning, delivering or charting. That cost lands in operations, not IT, so it’s rarely counted against mobility.
IT time. Setting up devices, chasing repairs and answering device tickets takes hours from an IT team that has other priorities. If the work is done in-house, it’s a real cost even if it isn’t invoiced.
Spares. Without a spare pool, a broken device means a worker waits for a replacement. With one, the spares are a cost that needs a line.
Lost devices. Lost and stolen devices are replaced at full price and carry a data risk until they’re locked or wiped.
Rushed procurement. When a model loses support or fails across a site without warning, replacements get bought fast, often at a worse price. Read ten ways to reduce the total cost of ownership of mobile technology for where these costs come from.
Capital or operating budget: buying devices vs device as a service
Mobile devices can sit in the capital budget, the operating budget or both, depending on whether you buy, lease or use Device as a Service (DaaS). The right choice depends on your cash position, how your organization treats devices for accounting, and who you want carrying the risk of failure and refresh. The table below compares the three, and it’s a starting point rather than accounting advice.
| Model | Cash flow | Accounting question to ask | Who carries failure and refresh risk | Fits when |
|---|---|---|---|---|
| Buy | Large upfront spend at refresh | Which capital cost allowance class applies | You | Capital is available and devices last their full life |
| Lease | Monthly payments for hardware | How the lease is treated under your accounting standard | Mostly you, for services and failures | You want to spread hardware cost but run services yourself |
| Device as a Service | Per-device monthly fee for hardware and services | Whether the fee is a service expense or contains a lease | Shared with the provider, per the contract | You want predictable monthly cost and fewer refresh spikes |
For purchased devices, the Canada Revenue Agency lists general-purpose electronic data processing equipment in Class 50 at a 55% rate. Whether a given handset or tablet falls in that class depends on its use, so confirm the treatment with your accountant.

Questions finance should ask IT before signing off the mobility budget
Finance gets a better mobility budget by asking IT seven specific questions before approving the number. Each one checks a line that’s often missing or guessed.
- How many devices are in service, by model, and when does each model stop receiving security updates?
- How many devices were replaced last year because they were lost, broken or failed?
- Which models come off warranty in the coming year, and what’s the repair plan for them?
- When were the wireless lines last audited, and how many were cancelled?
- What exchange rate are the device quotes based on, and are prices fixed?
- How many hours does IT spend on device setup, repairs and tickets each month?
- What does it cost to retire a device securely, and how many will be retired?
Budgeting mobility for Canadian organizations
Canadian mobility budgets have timing and cost factors that a generic template misses. The Government of Canada’s fiscal year runs from April 1 to March 31, and many public-sector buyers follow a similar cycle, so a refresh approved in a January budget may not be orderable until spring.
Devices priced in US dollars add currency exposure. Staging and repair done in Canada avoid cross-border shipping time and customs paperwork, which shortens the time a device is out of service. If you operate in Quebec, budget for French-language support and documentation where your teams need it.
Where PiiComm fits in mobility budget planning
PiiComm’s Strategic Sourcing team prices and sources devices across manufacturers, and works with IT on a refresh plan built from model support dates so the refresh line holds up through the year. For organizations that would rather pay a predictable monthly amount, Device as a Service bundles hardware, staging, management and refresh per device. See how strategic sourcing works.
It doesn’t fit everyone. If your fleet is small, on one model and refreshed on a fixed cycle, the budget structure and questions in this guide are usually enough on their own.
Questions finance leaders ask about budgeting for mobile devices
How much should we budget per mobile device?
The budget per mobile device depends on the device type, plan and services, so build it per model rather than using one figure. Add the device cost spread over its expected life, the wireless plan, accessories, staging, device management, expected repairs and retirement. A rugged handheld and a standard smartphone will have very different totals.
How do we forecast mobile device refresh costs?
Forecast mobile device refresh from your device list. For each model, record the units in service, the security update end date and the current replacement price. Models whose support ends during the budget year go in the refresh line, and a rolling refresh spreads the cost so no single year carries the whole fleet.
Should mobile devices be a capital or operating expense?
Mobile devices are a capital expense when bought and an operating expense when provided as a service, while leases depend on how your accounting standard treats them. The choice affects cash flow and who carries refresh risk. Confirm the accounting and tax treatment with your accountant before choosing a model.
How much contingency should a mobility budget include?
A mobility budget’s contingency should reflect fleet age and last year’s unplanned spend rather than a fixed percentage. An older fleet near the end of support needs more, because failures and forced replacements rise. Use your own replacement and repair history from the last two years as the starting point.
How do we stop wireless costs from going over budget?
Wireless costs stay on budget when lines are audited before budgeting, unused lines are cancelled, and plans are reviewed during the year. Tie line counts to the same headcount plan the rest of the budget uses, and check invoices monthly so new lines and plan changes are caught early.
When should we start next year’s mobility budget?
Start next year’s mobility budget about three months before it’s due. That gives IT time to pull the device list and support dates, audit wireless lines and get current quotes. If you’re refreshing in the first quarter, procurement lead times mean orders may need approval before the new year starts.
What costs are usually missing from a mobility budget?
The costs usually missing from a mobility budget are unplanned replacements, spares, staging, IT time spent on devices, secure retirement and the effect of exchange rates on US-dollar pricing. Downtime is missing too, because it lands in operations budgets. Naming these lines makes next year’s variance easier to explain.
Where to start with a mobility budget
Ask IT for the device list with model support dates and an audit of active wireless lines, then split the mobility budget into the eight lines above. Put any model that loses support in the next year into the refresh line, and state your exchange-rate assumption. If you’d like help pricing the refresh, talk to our strategic sourcing team.
