  • Features
  • Reviews

Plans and Pricing

Abacus offers three expense tracking packages that vary in their features and pricing. Your quote for the Professional and Enterprise plan may vary depending on company size

Abacus Starter Plan

The Abacus Starter plan is $9 per user per month and requires a minimum of 2 users. This charge is billed monthly, and included for this price are features such as direct deposit reimbursements, unlimited custom fields, mileage tracking, unlimited data storage, and some accounting, productivity, and travel integrations.

Abacus Professional Plan

Clients must receive a custom quote for the Professional plan, which will be billed annually. While the Professional plan has all the Starter features, it also includes options such as  commercial card integration, approval routing, more integration options, and accrual accounting synchronization.

Abacus Enterprise Plan

The Enterprise plan is another plan that requires a custom quote and will be billed annually. Users have access to all the same features as the Professional plan, and they may also integrate their CRM, use SSO, and access REST API.

Expense Reimbursement Simpler and Quicker

Abacus's features all aim at making the process of expense reimbursement simpler and quicker. By allowing users to link their bank accounts, approved expenses are securely paid out automatically. Users don't have to wait until the end of the month; it happens nightly.

Likewise, credit cards can be linked into the software and then Abacus will remind users when they have a new transaction on either their personal or corporate card, eliminating forgotten expenses.


Abacus has a lot of customization options. Big companies can group their organization into teams. Approval an either be set to one manager or set to require multiple levels of approval. Companies can also set their own expense rules, custom categorizes, and custom tags.


A lot of features help make expense submission and approval a lot simpler. Not only can users take pictures of receipts or scan them, they can forward online purchases to [email protected], which then converts the information into a report. Using the mobile app, users can quickly submit expenses no matter where they are. Managers can then review and approve expenses either in the office or on the go, as well. Managers can also communicate directly with employees through comments within Abacus. Audits, compliance and data portability are all covered through Abacus's software. Free accountant access, full admit trail, long-term data access, and full data portability keep companies safe.


Reviews of Abacus are overwhelmingly positive from users. It is described as "invaluable" and a "game changer." FourSquare, Mic, Pinterest, Y Combinator, and Betterment are all listed as happy Abacus customers.


The Bad

  • Limited Features
  • Apple and Android App Complaints

Limited Features

One missing feature is the ability to label an expense as reimbursable or non-reimbursable for non credit card expenses. This isn't going to affect all users, but certainly may cause a hassle in certain circumstances.

Apple and Android App Complaints

One of Abacus's biggest selling points is the ease with which users can submit and approve expenses on the go. However, the Apple iPhone app and the Android app have had a few complaints. Users of both have complained about crashes and problems installing the app. One recent review described the Android interface as being "not intuitive" and said it has been unable to do the few things it is supposed to be doing.


The Bottom Line

Abacus has attracted a number of happy customers including FourSquare and Pinterest, among others. Nearly all reviews in a variety of outlets are generally very positive.

Abacus seems to have accomplished this by essentially having one goal: make expense reimbursement as quick and painless as possible. They attempt to accomplish this by digitizing everything, doing as much in real-time as possible, and limiting manual input and matching.

By connecting credit cards and bank accounts, reminders and payments are daily and automatic. No more waiting until the end of the month or longer for payment or forgetting about a charge.

By downloading the Apple or Android app, employees and managers can submit and approve expenses on the road.

I have been reasonably happy with the service provided by Abacus. They've made their app and website pretty seamless and it's run great so far.
