Ramp vs Brex for a Law Firm's Advanced Client Costs

Filing fees, court reporter invoices, expert retainers, and process server charges are all costs a firm advances on a client's behalf, then bills back once the matter resolves or the client is invoiced. If the person who paid for it didn't tag the purchase to the matter at the time of the charge, someone in billing has to reconstruct that link later from a PDF receipt and a guess about which case it belonged to.

Both platforms let you set custom fields on a card or a transaction, so a matter number can be a required field before a charge posts rather than an optional note added after the fact. The difference shows up in how well that custom field syncs with your practice management or billing software, since a matter number typed once in the card platform and again in the billing system is a step someone will eventually skip.

Client funds held for a specific matter, retainers, settlement proceeds, and costs advanced by the client rather than the firm, belong in a separate IOLTA or trust account governed by your state bar's rules, not in the operating account a corporate card draws from. Neither Ramp nor Brex is built to hold or disburse trust funds, and that's a feature, not a gap: a card platform that touched trust money would create a compliance problem, not solve one.

What the card platform should do is keep firm operating spend, the costs the firm itself advances and expects to recover from a client invoice, cleanly separate from anything that could be mistaken for trust activity. If a partner ever needs to explain a transaction to an auditor or a bar examiner, the paper trail should show plainly that the charge came from the firm's own account.

Associates who regularly advance costs, filing fees, courier charges, deposition transcripts, benefit from having their own card with a spend limit set by practice group, so a routine filing fee doesn't require a partner's approval before it posts. Paralegals and administrative staff who make occasional purchases can usually work through a shared department card or a reimbursement flow instead, since issuing a card to every employee just to cover the rare expense adds administrative overhead without much upside.

The approval routing question matters more at a firm with several offices or practice groups, where a managing partner in one office shouldn't need to approve every deposition cost racked up by an associate elsewhere. Setting spend limits and approval thresholds by practice group, rather than by title alone, tends to match how firms actually delegate authority.

Ramp's onboarding is built around a startup-style card program rather than a traditional bank's credit application, which suits a firm adding cards for a new practice group or opening a satellite office without wanting to go through that process from scratch. Its expense automation, matching receipts to charges and flagging anything that looks off, reduces the manual review a bookkeeper or office manager would otherwise do line by line.

A firm with straightforward operating spend, software licenses, filing fees, office supplies, and a handful of associates who need cards, tends to find Ramp's setup fast enough that it doesn't become its own project.

A firm with multiple offices, a mix of entities, or cash reserves it wants to put to work between billing cycles has more reason to look at Brex, since its treasury features suit that kind of structure; ask directly how its accounting handles multiple offices or entities before you commit. A firm holding a large retainer pool or a settlement fund adjacent to, but never commingled with, its trust account may also value Brex's cash management tools more than a smaller single-office practice would.

The tradeoff is that a platform built around that kind of complexity tends to ask a newer or smaller firm to show more upfront, so a firm without a controller to manage that process may find the simpler path to an actual card in an associate's hand faster; confirm current onboarding requirements with each provider before you commit.

Issuing one card to a paralegal and having every associate route routine filing fees through them feels efficient until that person goes on vacation during a filing deadline, or until someone has to sort through a month of mixed-matter charges after the fact. The habit usually starts small, one card for occasional costs, and turns into the default because setting up new cardholders feels like a chore.

The fix costs almost nothing once the platform is already in place: give each associate who regularly advances costs their own card with a matter-tagging requirement, and reserve the shared card for genuinely rare purchases like a one-off courier run. The paralegal keeps doing paralegal work instead of becoming the firm's unofficial expense clerk.

Avoid the shared card problem with these safeguards:

• Make the matter number a required custom field on the card or transaction, so a charge cannot post without it.
• Check that the field syncs with your practice management or billing software, so nobody types the same matter number twice.
• Keep client retainers and settlement proceeds in your IOLTA trust account, never in the operating account a corporate card draws from.
• Give associates who regularly advance costs their own card with a limit set by practice group, so routine filing fees skip partner approval.
