The deduction you lose is almost never the one you decided against. It is the receipt that went through the wash, and the one you meant to file in April.

A 1099 business has no bookkeeper and no expense policy. There is you, a phone, and a paper receipt that fades. Most missed deductions are not judgment calls about what qualifies — they are records that stopped existing.
The second failure is slower. Receipts get photographed but never sorted, so at tax time there is a folder of images and no totals. A pile of evidence is not a Schedule C.
Photograph the receipt when it is in your hand. If you turn on text recognition, SoloDesq reads the merchant, amount and date so you are confirming rather than typing. If you turn on AI categorization, it suggests the Schedule C line and you approve it. Both are opt-in — the app works with neither.
An expense logged here is not filed away on its own. It lands on your running Schedule C, moves your quarterly estimate, and shows up in the CSV at year end. That join is the reason to keep the five tools in one place rather than four apps and a spreadsheet.
Mileage behaves the same way. A logged trip becomes a deduction at the IRS rate for that trip’s date, without you re-entering anything.
Photograph the receipt once. SoloDesq keeps the total, the category and the year-end export.
SoloDesq is bookkeeping software, not a tax preparer or tax advisor. Category suggestions are suggestions; you confirm every one. For advice on your own return, talk to a qualified tax professional.
