CPACharge vs. PayPal vs. BizPayO: Independent Evaluation from Perplexity

Executive conclusion

For an accounting firm processing $1 million annually—50% through ACH and 50% by card—BizPayO’s economics are fundamentally different if the firm fully recovers card fees:

Net annual savings with BizPayO:

• Approximately $15,599 vs. PayPal
• Approximately $15,688 vs. CPACharge

This analysis assumes the firm configures BizPayO so that clients recover 100% of card acceptance costs, while the firm continues to absorb ACH expense. BizPayO publicly describes 2.99% card processing and permits the firm to set a recovery fee—illustrating that a 3% recovery fee can cover its 2.99% card cost.  

Volume assumptions

The specified payment profile produces the following annual transaction base:

The fractional transaction count is simply the mathematical implication of an average $750 payment. In actual operations, the firm would have approximately 1,333 or 1,334 transactions annually, so final fees would move by only a few dollars depending on the precise payment mix.

This is an especially useful comparison structure for CPA firms because it separates the two cost drivers:

• ACH expense, which is usually paid by the firm and can be materially lower than card acceptance.
• Card expense, which may either be absorbed as a cost of collections or passed to the card-paying client through an appropriately structured fee-recovery program.

Detailed cost model

BizPayO: 100% card recovery

BizPayO lists ACH/eCheck processing at 0.89% and card processing at 2.99%. Its Basic plan is presented at $19 per month when billed monthly. BizPayO’s fee-recovery workflow is designed to allow a firm to add a client-facing card recovery charge; its example notes that a 3% recovery fee can offset a 2.99% processing fee.bizpayo+1

Effective net cost to the firm: 0.4678%

PayPal Invoicing

For domestic invoice payments by standard credit or debit card, PayPal’s published merchant pricing is 2.99% plus $0.49 per transaction. PayPal’s Pay by Bank/ACH rate is 1%, capped at $10 per transaction.checkthat+1

Effective cost: 2.0277%

CPACharge

CPACharge’s published core pricing is 2.99% plus $0.30 for Visa, Mastercard, and Discover payments; eCheck/ACH is 1% per transaction, capped at $10. It lists a $10 monthly standard subscription charge and has disclosed a $7.99 monthly pass-through allocation associated with card-network costs.  

Effective cost: 2.0366%

CPACharge is narrowly more expensive than PayPal in this exact model—about $89 annually—despite a lower $0.30 fixed card fee. Its disclosed monthly subscription and pass-through allocation offset its $0.19 per-transaction card-fee advantage. This is too small to be a strategic deciding factor; workflow, practice specialization, payment limits, and client-payment design should matter more.

Why BizPayO wins here

BizPayO’s approximately $15,600–$15,700 annual advantage does not primarily arise from a better baseline card processing rate. All three providers are modeled with essentially a 2.99% percentage card cost. The advantage has three sources:

Compared with CPACharge, BizPayO’s advantage reflects:

The operational takeaway is straightforward: the largest lever is not negotiating a few basis points; it is increasing ACH adoption and deciding whether card convenience should be funded by the firm or the card-paying client.

Compliance and payment-type constraints

BizPayO describes recovery through surcharge or convenience-fee workflows and notes that firms can set their own recovery amount. Its published FAQ uses a 3% recovery illustration against a 2.99% card fee.  

Before activating a program, a firm should validate all of the following directly with BizPayO:

• Whether the chosen program is a credit-card surcharge, convenience fee, or cash-discount/dual-pricing program.
• Whether the fee is legally permissible for the firm’s location and client locations.
• Required pre-payment, invoice, and checkout disclosures.
• Card-network registration, notice, maximum-fee, and receipt-disclosure requirements.
• Correct handling of debit and prepaid cards, which generally cannot simply be treated like credit cards for surcharge purposes.
• How the fee is calculated if the processor also charges a fee on the recovery amount itself.
• Whether fee recovery is appropriate for all client segments, including tax clients, advisory clients, business clients, and high-net-worth individuals.

The model assumes full recovery, but a firm should not assume that every card payment will be eligible, accepted by the client, or structured in precisely the same way.

Provider recommendation

BizPayO: strongest net-cost option

At a net cost of approximately $4,678, BizPayO reduces payment expense by more than three-quarters compared with absorbing card fees.

CPACharge: strongest accounting-specific operational option

CPACharge is often the better fit when the firm’s priorities are:

• A platform designed specifically for accounting professionals.
• Larger-dollar ACH receipts where a $10 cap is highly valuable.
• Purpose-built collection workflows, trust or client-account practices where applicable, payment pages, and accounting-oriented support.
• A willingness to absorb payment cost to maintain a simple, premium client experience.
• A preference for practice specialization over aggressive card-fee recovery.

CPACharge’s direct cost is roughly $20,366 in this model, but that cost may be justified where it shortens collections cycles, improves reconciliation, and better fits the firm’s existing systems.

PayPal: best only for broad familiarity or existing use

PayPal can make sense where immediate recognition and low adoption friction dominate the decision. But it is less compelling for a sophisticated CPA firm unless it is already embedded in the firm’s billing process.

It is nearly cost-neutral with CPACharge in the base model, but its client payment routing requires more care. Standard invoiced card payments are modeled at 2.99% plus $0.49, whereas PayPal/Venmo payment paths can carry a higher 3.49% plus $0.49 fee.checkthat+1

Final recommendation

For this exact fact pattern, I would treat BizPayO as the leading candidate if the firm is committed to an ACH-first policy and can legitimately recover the full card cost. The projected net processing cost is only $4,678 annually, compared with approximately $20,300 for CPACharge or PayPal.

Before implementing, obtain written confirmation of:

• The exact BizPayO plan, ACH rate, card rate, fixed transaction charges, network fees, and any ACH cap.
• The precise amount that can be recovered on eligible transactions and whether the recovery fee itself is processed fee-free or subject to processing cost.
• Credit versus debit card treatment, card-brand notices, state-law limitations, and required disclosures.
• A report of the firm’s actual ACH transaction-size distribution for the prior 12 months.
• The expected client-payment mix after introducing an ACH-first and card-recovery policy.
