Abacus for the win!

We used Abacus across the entire company. We used Abacus for logging all different types of expenses. From food, drink, travel, purchases made on behalf of the company, mail, cell phone reimbursement, as well as other stipends decided on by the company. Best part was you can really choose different categories when logging your expenses, so the finance team knows why you submitted, what you were doing, who was there (if it was a client meeting), etc. You can make Abacus as custom as you'd like by even imputing different conferences so every expense was logged under one event for, again, the finance team to keep track of how much is being spent per event (that's what I used Abacus for most often- travel expenses associated with conferences).
