Before I used SparkReceipt, I took pictures of receipts using my phone and downloaded them to my computer. Next, I itemized each receipt in a Google Sheet, attached the photos, and then emailed the completed sheet to our accountant. If you haven't written 20-30 lines of expenses on a sheet every week, know that it is time-consuming.
Now, I just forward the receipts to SparkReceipt, download the report that already contains the photos, and share them with the accountant (Done in 5 minutes). This saves me 2 hours weekly, roughly 8 hours a month. It basically pays for itself.
