Zoho Expense, Expensify, Smart Receipts and Adobe Scan compared for receipt scanning, mileage, reports and business expenses.
The parking receipt fading in a wallet and the hotel invoice resurfacing in March are universal freelancer problems, and they are unfixable at month end. The moment to capture a receipt is the moment it is handed over, ideally by photographing it so software can pull out the amount, date and merchant before the paper disappears. After that, needs split in two. Companies want approval workflows and standardised export; solo workers want a generous free tier and mileage tracking; sometimes the right tool is simply a very good scanner. The 3 apps in this guide cover those three situations, from corporate claim systems to a plain PDF.
Zoho Expense has the most capable free plan in the group, with receipt scanning, GPS mileage and multi-currency support, and the highest ratings.
Its free tier is genuinely usable rather than a demo: automatic receipt capture, GPS-tracked mileage and multi-currency expenses are enough for a freelancer or small team without touching a paid plan, and user ratings lead the category. Reports export cleanly for an accountant. The caveats are about fit rather than function. It works best when a business already uses the wider Zoho ecosystem, initial configuration demands some effort to get rules and categories right, and Spanish-language support is limited. Outside the Zoho world it is still excellent value; inside it, the obvious choice.
Expensify reads a receipt photo into a completed expense automatically and provides the approval workflows and reports standard in corporate claims.
It is the international reference for business and travel expenses: photograph a receipt and the amount, date and merchant are extracted with no typing, expenses roll into exportable reports, and managers approve them through built-in workflows. For a company standardising how every employee claims, that maturity is exactly why it dominates. Its scale is also its weakness for individuals. It is designed around organisations, so a freelancer gets corporate machinery they do not need, per-user pricing is relatively high, and much of the interface remains English-only. Choose it when a team is paying.
Adobe Scan turns receipts and invoices into clean, text-searchable PDFs with strong image correction, free and without watermarks.
It is not expense software, and that is sometimes the right answer. Adobe's imaging engine delivers the best capture quality of the group, perspective correction and background cleanup make crumpled receipts legible, and the OCR layer means an old invoice is full-text searchable rather than buried as an image. Exports are free and watermark-free. The edge cases: a free Adobe account is required, advanced Acrobat features cost extra, and OCR processing needs a connection. It also will not categorise expenses or build claims; pair it with manual spreadsheets for that.

Questions & answers
Is a photographed receipt valid for tax purposes?
In Spain, digitising invoices and receipts is allowed, but destroying the paper original requires the process to run through digitisation software certified by the Agencia Tributaria. The apps in this guide are generally not certified for that purpose, so the practical rule is to keep the paper for receipts that matter and treat the app as an internal control and backup. When in doubt, the paper original plus a digital copy is the combination that survives an audit.
What is the best free expense tracker app?
Zoho Expense, by a clear distance: its free plan covers a freelancer or very small team with automatic receipt reading and mileage included. Smart Receipts is the alternative for someone who wants simplicity and no company account, while Expensify is built for organisations and its per-user pricing reflects that. Adobe Scan solves only the capture half of the job but does it free and without watermarks.
How do I document car mileage for claims?
Zoho Expense records each trip by GPS and applies the per-kilometre rate you configure, generating the supporting document automatically, which is valuable because travel is usually the worst-recorded expense line in a small business. Retaining the generated report alongside the purpose of each trip keeps the claim defensible. The tax treatment of those costs depends on individual circumstances, so confirm the details with an accountant rather than assuming a rate applies.
Do these apps connect to accounting software?
Expensify and Zoho Expense export the usual formats and integrate with several mainstream accounting tools, although direct connections to specifically Spanish accounting software remain limited. In practice the common workflow is exporting a spreadsheet or PDF and handing it to an accountant, which every option here supports. Treat deep integration as a bonus and clean, consistent export as the feature that actually matters month to month.
