Airbase or Procurify for a CPA Firm's Own Back Office
For a CPA firm's own back office, the better fit between Airbase and Procurify depends mostly on how busy-season staffing works: card-first Airbase suits seasonal hires, and request-first Procurify builds a cleaner peer review trail. Both address problems you would diagnose for a client, such as a tax-software renewal nobody remembers negotiating.
The honest answer to which one fits is that it depends on how your busy-season staffing works more than on anything else.

Does This Help With Our Tax and Research Software Renewals?
Tax and research software renewals, the platforms firms rely on for return preparation and technical research, tend to auto-renew on annual contracts that were negotiated by a partner who may no longer be at the firm. Both Airbase and Procurify will flag an upcoming renewal if the contract is loaded into the system with an end date, which is the real work: getting every existing contract entered once, correctly, rather than waiting for the tool to somehow already know about a renewal nobody told it about.
What About Independence Rules on Vendor Relationships?
Independence rules matter more for vendor selection than most spend platforms account for. If your firm audits a company, you generally can't accept certain non-audit services or financial relationships from that same client or its affiliates, and neither Airbase nor Procurify has any awareness of your independence obligations. That check has to happen before a vendor or client relationship is entered into the system, as a policy your partners enforce, not as a feature you're buying.
Add a manual independence check at vendor intake:
- Ask whether the vendor also does business with, or is paid by, any of your attest clients before signing anything.
- Flag any overlap for partner review, since independence rules exist to catch exactly this situation.
- Record who reviewed the vendor and when, so the decision can be shown to an outside reviewer.
- Keep the check outside the spend platform, because neither Airbase nor Procurify knows your independence obligations.
How Does Seasonal Staffing Change the Answer?
A firm that brings on seasonal contract preparers every winter has a predictable spike in 1099 relationships and short-term software seat additions that a card-first platform handles more gracefully than a request-first one, because seasonal staff need to be productive immediately, not waiting on a multi-step approval during the first week of busy season. That matters more given how expensive qualified seasonal help already is: national median pay for accountants and auditors sits at $83,680 a year1, which is exactly why losing a week to a stalled software-seat approval is a real cost, not a minor inconvenience. If your firm instead maintains a smaller, more stable year-round vendor list with just a few large annual contracts, Procurify's more deliberate request flow costs you less in practice, since you're not running that gauntlet repeatedly under deadline pressure.
Which One Handles Peer Review Documentation Better?
For firms subject to peer review, having a clean, exportable approval trail on significant purchases, who requested it, who approved it, when, matters more than which platform produced it. Procurify's request-first model builds that trail by default, since nothing happens without a logged request and approval. Airbase can produce the same trail, but it depends on approvers actually reviewing flagged card transactions rather than letting them clear automatically within a set limit, so the discipline has to be enforced by policy either way.
Where Should a Small Firm Just Start Manually?
A firm under roughly 15 people usually doesn't need either platform yet. A shared vendor spreadsheet with renewal dates, reviewed by one partner each quarter, catches most of what these tools catch, and the partner time spent configuring approval workflows is better spent elsewhere at that size. The trigger point is usually adding a second office, a second approving partner, or enough seasonal contractors that nobody can hold the full vendor list in their head anymore.
A Common Mistake: Blanket Independence Rules That Slow Everything Down
Some firms respond to independence risk by routing every vendor purchase, regardless of size or client connection, through the same manual partner review, on the theory that it's simpler than deciding case by case. In practice that just trains staff to route around the process for anything under a few hundred dollars, because waiting a week for partner sign-off on a research-database renewal feels disproportionate to the risk, and now you have shadow purchases with no review at all.
A better split: build a short list of vendor categories that actually carry independence exposure, audit-client software, investment products, anything tied to an attest engagement, and route only those through partner review, while routine operating purchases (office software, practice-management tools, staffing platforms) clear on a normal approval path. Both Airbase and Procurify can enforce that split with category-based routing rules, but the list of flagged categories has to come from someone who understands your independence policy, usually the quality-control partner, not from a default template that treats every vendor the same way.
What Good Looks Like
A well-run CPA firm can produce a complete, dated approval trail for every significant purchase on demand, whether for a peer reviewer or an internal partner meeting, without anyone reconstructing it from memory.

How to Get Started

Seasonal contract preparer invoices and research-platform renewals both benefit from routing through BILL rather than a partner's personal email, if only because it keeps the peer-review trail in one place.
Every seasonal preparer paid outside payroll needs a 1099-NEC, and Tax1099's bulk W-9 collection before busy season starts is the difference between a clean January and a scramble.
Firms that carry a large cash balance through the slower months between busy seasons are a reasonable candidate for Mercury's higher-yield account options, worth reviewing alongside your firm's own banking relationship.
Frequently Asked Questions
Do either of these tools help with client trust accounting?
No, and don't try to make them. These platforms manage your firm's own vendor purchases and internal spend. Client trust or escrow accounting has its own rules and typically needs software built specifically for that purpose, kept entirely separate from your firm's general operating spend.
Should partners be exempt from the approval workflow?
Some firms exempt partners for speed, but that's usually a mistake. Partner-level purchases, especially technology contracts and vendor relationships, are exactly the ones peer review or an outside audit is most likely to ask about, so keeping them inside the same approval trail as everyone else is worth the minor friction.
How do we handle a vendor that serves both our firm and one of our audit clients?
Flag it for partner review before signing anything, since that overlap is precisely what independence rules are designed to catch. Neither platform will surface this on its own, so build a manual check into intake: does this vendor also do business with, or get paid by, any of our attest clients?
