Sage Fixed Assets exists because depreciation is one of those problems that looks like a spreadsheet until the first time it is not. It tracks an asset from acquisition through transfer, revaluation and disposal, and it keeps separate books for financial reporting and for tax, which is the part the spreadsheet always gets wrong.
What it does well
The US tax content is the reason to buy it. MACRS, bonus depreciation, Section 179 limits and the mid quarter convention are built in and maintained by Sage as the rules change, so you are not reading IRS Publication 946 in February to find out what moved. It carries multiple books in parallel, which means your GAAP number and your tax number come from one asset record rather than two spreadsheets that disagree.
Reporting is genuinely audit ready. Form 4562 comes out of the box, and the depreciation schedules are the format auditors expect, which shortens the conversation considerably.
Canada
Canadian capital cost allowance is supported, including the half year rule and the CCA classes. If you run assets in both countries this is one of the few products in the Sage line that handles both without a second license.
Where it frustrates people
It looks its age. The interface is dense and unapologetically built for accountants, and nobody has ever called it pleasant. Pricing is quote only through a partner, which makes budgeting awkward, and the product is priced for organizations with enough assets to justify it. Under roughly a hundred assets, a well kept spreadsheet and an hour with your accountant is still the honest answer, and we would rather say that than sell you something.
