BILL vs Tipalti for Accounting and CPA Practices

Most of the year, a firm's payables look thin: research and audit software, a lease, a handful of vendors. Then filing season hits and temporary staff, overtime-related costs, and rush vendor orders for printing or e-filing services spike invoice volume in a way that a manual approval process, built for the quiet months, struggles to absorb without becoming the bottleneck partners complain about every year and forget about every summer.

Almost every CPA firm's vendor list is domestic: software vendors, a landlord, insurance, professional associations. BILL's approval routing handles that cleanly, with the advantage of syncing directly into whatever accounting platform the firm already runs client books on, since that's likely the same system the firm uses for itself. For most single-office and regional practices, that's the whole answer, and the setup effort is modest enough that a practice manager can own it without pulling a partner away from client work to configure it.

Tipalti becomes relevant less often for a CPA firm's own books than for one specific pattern: firms that build out an outsourced or offshore staffing model, using contracted preparers or reviewers based in another country during peak season. If your firm pays a seasonal reviewer overseas the same way it pays its landlord, through a manual international wire figured out under deadline pressure, Tipalti's payee onboarding and multi-currency rails remove exactly that friction.

Whatever a firm chooses for its own operating payables, it should never touch client trust or escrow funds the firm holds in a fiduciary capacity, for engagements like estate work or client fund administration. Neither BILL nor Tipalti is a trust-accounting system, and treating either one as if it were is a compliance risk with no upside; keep that recordkeeping in a dedicated trust ledger, reconciled separately, full stop.

Before the next busy season starts, walk through what happened last time an unusual vendor invoice showed up during the final week of a filing deadline: who approved it, how long that took, and whether anyone was waiting on that approval to close out client work. If the answer involves a partner tracking someone down by phone during a deadline crunch, that's the workflow gap worth fixing before deadline pressure returns, not after. Run that same walkthrough for the summer months too, since a quieter season is exactly when a firm has the bandwidth to fix a process it won't have time to touch once deadlines start piling up again.

Walk through your last busy season in this order:

1. Pick the last unusual vendor invoice that arrived during the final week of a filing deadline and trace what happened to it.
2. Record who approved it and how long that took from arrival to sign-off.
3. Check whether any client work was waiting on that approval before it could be closed out.
4. Ask whether a partner had to be tracked down between client deadlines, which signals that a fast lane for recurring vendors is missing.
5. Set up lower-friction approval for pre-approved recurring vendors before next season, keeping real review for unusual or above-threshold invoices.

Say the firm brings on a staffing agency to supply reviewers for the final six weeks of tax season, with weekly invoices tied to hours worked. In a manual process, that invoice competes for a partner's attention against actual client deadlines and usually loses, which delays payment to a vendor the firm will want to use again next year. A standard approval workflow with a lower-dollar threshold for pre-approved recurring vendors like this one keeps the invoice moving without needing a partner's attention every single week.

A single-partner practice can get away with one person approving nearly everything, but a firm with multiple offices or several equity partners needs approval routing that reflects who actually has budget authority for what. Office-level overhead should route to the local managing partner, while firm-wide software or facility decisions should route to whoever holds that budget centrally, and a tool that can't represent that split forces someone to manually reroute invoices that landed with the wrong approver, which is exactly the kind of friction that grows worse as a firm adds locations rather than better.
