We care about this one because it's come up in real life. When you run everything through one shared card, a problem anywhere becomes a problem everywhere.

With Ramp, we have a card on file with every single vendor/software subscription. If it ever gets compromised, we cancel one card, we're not spending a weekend updating payment details across every tool in the stack.

You can lock cards to specific merchants, set any limit you want, and spin up a one-off card for a vendor and close it the moment the transaction clears.

Tap the card, get a text, reply with a receipt photo. That's genuinely the whole process for your team and no other expense management tool does it this well.

The text messages Ramp sends are friendly and easy, so even your most non-technical team member can use it. Then Ramp handles the categorization, memo, and accounting sync automatically.

Transactions show up almost immediately after a purchase, approvals come with a recommendation so you can move through them fast, and once you discover CMD+K search you'll wonder how you navigated finance software without it. It doesn't sound like much until you've used something slower.

Ramp surfaces duplicate subscriptions, unusual spending, and cost-saving opportunities automatically. It becomes more valuable as your team and software stack grow.

• Credit card rewards

BILL Spend & Expense gives us so much control when it comes to our spending. We can easily create a virtual credit card, set a budget and Quickbooks category within seconds for each different vendor. We simply set a budget for each credit card for the exact amount that we know will be charged. If a subscription service decides to increase their pricing and charge our card, it will decline. And we like that, because we want to be the one deciding if someone should charge us more or not. 💪

Because we're able to put virtual cards down with each vendor, BILL Spend & Expense allowed us (and our vendor) to actually catch a person that committed fraud by stealing and using our credit card 🤯 Of course, the employee of our vendor was fired. Catching them would have been impossible to pin down if we had a generic credit card on file.

Transactions are logged in real time and can be categorized right away. Once synced with your accounting software, everything lines up automatically, so month-end reconciliation is faster and less error-prone. This cuts down a lot of the manual cleanup at month-end.

Have multiple employees that need their own corporate card? Create a card for them and set a spending limit, that's all you need to do. You can change the spending limit for each employee, make it $50 or $500, BILL Spend & Expense cards allow you to be flexible.

If they leave the company, simply freeze the card (you have total control—just think of what the process is like with a typically corporate card. Issuing a new card for an employee is an annoying process, as is cancelling it). Not to mention the positive affect it has on your employees, as they get to feel empowered and like a trusted part of the team.

BILL Spend & Expense works with QuickBooks Online, QuickBooks Desktop, Oracle NetSuite, and Xero among others. If your system isn't supported, you can still export CSVs and import your data manually. Either way, it keeps your records connected without forcing you to change your existing accounting setup.

The rewards are pretty standard with others in the business credit card space, getting somewhere around 1–1.5% on all categories, with a bit more in certain categories (higher % when making payments weekly—less if made bi-weekly or monthly).

One customer that we recommended BILL Spend & Expense to started using it and quickly saw his reward balance grow. He decided to use the reward funds as Christmas bonuses for his employees. He said, "it's money that's just sitting there, and if I can give them a little extra to take home at the end of the year, it's something cool I get to do."

QBO helps companies manage core financial tasks like invoicing, expense tracking, bank reconciliation, financial reporting, and tax preparation.

This is one of those areas that it makes sense that they cover, but you can tell it was an add-on versus being their core service. Payroll is boring, and hey, QBO does the job, it's just not a straightforward user-experience, and let's just say we used it for 4 years before switching to Gusto, and there's not a single bone in my body that misses QBO for payroll. It was also incredibly painful closing it down with them, reporting to all the Department of Labor agencies, and everything. Save yourself the time and skip out on QBO for Payroll.

If you compare QuickBooks Online to any of the best time tracking software on the market, you'll see just how wildly barebones, slow, and underwhelming it is. Even just the process of logging into QBO feels like you're pushing a boulder uphill, now you need to do it any time you track software? No thanks, I'll pass.

They designed it more to be for people who just need to submit their time one-per-day or once-per-week, they are building to check a box, not to be leading the time tracking space.
