5 Paychex Alternatives for Small CPA Firms in 2027

The short answer for a small CPA firm

A Paychex alternative is a payroll provider that runs your own staff's pay, tax deposits and tax filings under a contract you can price and compare. This guide covers your firm's own payroll, not payroll you run for clients. Three questions settle most of the choice: whether you want payroll alone or payroll with HR, time tracking and benefits; whether your books already live in QuickBooks Online; and whether you can get a firm price in writing before you move.

TL;DR: If your books are in QuickBooks Online, price QuickBooks Workforce Payroll and OnPay first, because both publish per-month plan lines you can model. If you want HR, IT and payroll in one system and can accept a quote, price Rippling. Price ADP and Gusto too, knowing that ADP is quote-based and this check could not open Gusto's pricing page. Paychex publishes no plan prices, so every Paychex comparison starts with a quote.

Key Takeaways

• Two of the five alternatives publish plan-level prices on pages we could open: QuickBooks Workforce Payroll and OnPay. Per-employee fees drive most of the monthly cost at small firm sizes.

• Rippling, ADP and Paychex are quote-based.

• Gusto's current prices were not verified for this guide, so this article prints no Gusto price.

• IRS deposit rules matter as much as the monthly fee, because a large accumulation of payroll taxes can force next-business-day deposits.

• For a 10-employee example, the two entry plans with published per-month lines cost the same per month before add-ons.

• Get the all-in first-year cost in writing, including base fees, per-employee fees, add-ons and any promotion end date. Aggregator sites in this check gave conflicting numbers.

How we evaluated these tools

This is an informed buyer's guide built from public information: vendor pricing and product pages where they could be opened, IRS guidance, and trade comparisons. The weights below set the order of the profiles and the questions to ask. They are our judgment for a firm that runs its own payroll, and we did not assign a single numeric score to any product. We left Justworks out because its pricing and product pages returned errors when we opened them.

If HR or benefits drive your decision, shift weight from ledger fit toward scope match.

Feature matrix and page status

The matrix below shows what each vendor states on the page we opened. It is not a test of the products.

What the published prices show

Pricing checked October 28, 2026. Only figures read on vendor pricing pages appear as prices here, and each one carries its citation.

Intuit's Workforce Payroll page prints per-month lines of $44 plus $6.50 per employee for Simple Start, $62.50 plus $6.50 for Essentials, and $101.50 plus $10 per employee for Premium plus Plus, according to Intuit (2026). The same page also prints lines without a billing period, so model only the per-month lines and confirm the billing period with Intuit before you sign.

OnPay base fee: $49 a month plus $6 per worker according to OnPay (2026). The footer on that page says pricing starts at $55 per month, which does not match the $49 base, and the page does not explain the difference according to OnPay (2026). Ask OnPay to confirm the base before you compare.

Rippling's pricing page could not be read in this check, so this article prints no Rippling price and treats Rippling as quote-based.

ADP's small-business payroll is aimed at firms with 1 to 49 employees, and every tier on the page is quote-based, according to ADP (2026). Paychex shows a Request Pricing button on every payroll plan. Its promotion of up to six months of payroll service at no charge applies to the payroll component only, for eligible new clients with 1 to 250 employees on a one-year agreement, according to Paychex (2026). Paychex runs time-limited payroll promotions, so check current terms before you plan a switch.

Gusto's current prices were not verified for this guide, so this article prints no Gusto price. A comparison from Patriot Software, which sells payroll itself, lists Gusto's Simple, Plus and Premium tiers, but a competitor's comparison is not a price source for this article. Get Gusto's current tiers from Gusto directly.

The table below uses only the inputs cited above. The math is list price times headcount, before taxes, add-ons and setup fees.

Take a firm with 10 employees. Using the list prices cited above, the Simple Start plan on QuickBooks costs $44 plus 10 times $6.50, which is $109 a month or $1,308 a year. The Premium plus Plus plan costs $101.50 plus 10 times $10, which is $201.50 a month, or $92.50 a month and $1,110 a year more than Simple Start. OnPay's Payroll Essentials comes to $49 plus 10 times $6, or $109 a month, the same as Simple Start before add-ons. If the firm posts runs like these to its ledger through an OAuth connection, the scope string com.intuit.quickbooks.accounting in Intuit's scopes documentation grants access to the QuickBooks Online Accounting API.

Five alternatives, one profile each

Each profile covers best fit, limitations, implementation and the primary evidence we could open. Paychex is treated as the baseline in its own paragraph at the end of this section.

QuickBooks Workforce Payroll

Best fit: Firms whose books already sit in QuickBooks Online and who want payroll entries next to the ledger. Simple Start and Essentials carry scheduling-only time tracking, while Premium plus Plus adds a workforce app for mobile or kiosk clock-in, per Intuit's page.

Limitations: Essentials includes 3 users and Premium plus Plus includes 5 users. Automated HR workflows are limited to five custom configurations at any one time, and benefits administration has limited availability with additional fees. A Patriot Software comparison, published by a payroll competitor, lists 7 providers and calls QuickBooks Payroll's base prices higher than several other options on its list, according to Patriot Software (2026).

Implementation: Simple Start offers next-business-day direct deposit with a 5:00 PM payroll cutoff, and the higher tiers offer same-day deposit with a 7:00 AM cutoff, per Intuit's page. Confirm the cutoff times against your pay calendar before you choose a tier.

Primary evidence: Intuit's Workforce Payroll pricing page.

OnPay

Best fit: Firms that want a visible base fee plus a per-worker fee, unlimited pay runs and payroll for workers in any number of states. The page says base plans include W-2s, 1099s and year-end filings, plus federal, state and local tax filings, and it lists no implementation or integration fees.

Limitations: The footer price conflicts with the base price noted above. HR, time tracking and benefits are separate add-ons, and the page offers accountant discounts tiered by client count. The Patriot comparison, from a competing payroll vendor, lists the lack of an automatic payroll feature as an OnPay drawback, so confirm that your payroll workflow works without it before you buy.

Implementation: The page states no implementation or integration fees. Health, workers' comp and 401(k) add-ons cost depends on the plan selections you make.

Primary evidence: OnPay's pricing page.

Rippling

Best fit: Firms that want HR, IT and payroll in one system and expect to add modules over time. The pricing page groups products into HCM, IT, Payroll, Finance and Global, so the scope is wide.

Limitations: There is no published plan list or payroll-only total, so the first firm number comes from a quote. Module choices drive the cost, and we could not read the page to confirm any base fee.

Implementation: Rippling documents a REST API. Confirm API access, implementation scope and any setup terms in the written quote.

Primary evidence: Rippling's pricing page and Rippling's REST API documentation.

ADP small business payroll

Best fit: Firms with 1 to 49 employees that want a large national provider and may later add HR packages. The page lists Essential, Enhanced, Complete Payroll & HR+ and HR Pro options.

Limitations: No tier shows a price on the page we opened, so every comparison needs a written quote. The "up to 6 months FREE" offer on the page comes with separate terms. The Patriot comparison also says a custom quote is required for ADP's RUN product.

Implementation: Expect a sales conversation before any number appears. Ask for the terms of the free-months offer in writing, including what happens to fees after the free period.

Primary evidence: ADP's small business payroll page.

Gusto

Best fit: General small-business payroll with an accountant-facing program. The Patriot comparison describes Gusto's accountant discounts or revenue share once a firm has at least three clients, and it cites Gusto's course and certification library as a strength.

Limitations: Gusto's tiers and prices were not confirmed in this check. The same Patriot comparison notes that support quality varies by tier.

Implementation: Ask for current tier prices, state coverage and integration details in writing before you compare.

Primary evidence: No Gusto page was verified for this guide. The only evidence here is the Patriot Software comparison, which is a competitor's page.

Paychex is the baseline because it is what the reader is comparing against. Its payroll plans (Basic, Foundations, Advanced and Complete) and its HR packages (HR Pro and HR PEO) are all quote-based, and its Time & Attendance, Health Insurance and Workers' Comp add-ons are listed without prices. The page labels Foundations "Best Value," which is a Paychex label, not an independent rating.

Where the proposed workflow meets month-end and deposits

The pain usually shows up after the switch, when a payroll run finishes in one system and the ledger still needs matching entries. A proposed US Tech Automations workflow for that step is configurable, not a live deployment, and it would run as follows. The trigger is a payroll run marked approved, or a nightly export file landing in a shared folder. The action pulls the payroll register through the provider's export or API where the firm's plan includes it, maps gross wages, employer taxes and deductions to ledger accounts, and stages the entries in a review sheet. The output is that staged set plus a variance list for any line that moves from the prior run by an amount the firm sets. Prerequisites are an approved API connection or scheduled export from the payroll provider, an OAuth connection to QuickBooks Online, and a written chart-of-accounts mapping signed off by a bookkeeper. The human review point is the bookkeeper's approval before anything posts to the ledger.

Next-day deposit trigger: $100,000 accumulated in a deposit period according to IRS (2026). A second proposed workflow watches the deposit side. The trigger is each approved payroll run; the action adds employer and withheld taxes to a running total for the current deposit period and compares it with that IRS threshold; the output is an alert to the named payroll owner as the total approaches it. Schedule type depends on lookback taxes, since IRS guidance sets monthly schedules at reported taxes of $50,000 or less and semiweekly schedules above that, according to IRS (2026). This workflow only watches and alerts. The firm or its provider still files and remits, and a person confirms the schedule each quarter.

Build it yourself or add a layer

Many firms will stitch this together in Zapier, Make or n8n, or script it in-house. Those tools can keep run histories, retries and error branches when they are configured that way. The firm still has to design and own idempotency so a retried run does not post twice, escalation to a named person, access controls on payroll data, and maintenance when the provider or QuickBooks changes an API.

A proposed US Tech Automations design would differ in the parts DIY builds often skip: a run-ID check before anything is staged, a named reviewer for variances, and a log of each run for audit. Its prerequisites are the same as above, meaning API or export access, an OAuth connection and an approved mapping, and its review points are the bookkeeper's approval and the quarterly schedule check. Confirm those in scoping, because this is a design that would be configured for your firm, not a result we can show.

When NOT to use US Tech Automations

A simpler tool wins in three cases. If the firm runs payroll for a handful of staff and the built-in QuickBooks reports already support the tie-out, a workflow adds maintenance without saving time. If the firm wants its provider to own every step and does not want to review staged entries, a configured design is the wrong fit. If the firm posts one manual entry a month and it takes minutes, the automation is not worth the setup.

Who this is for

This guide suits a small CPA firm that runs its own staff payroll, keeps its books in QuickBooks Online or a similar ledger, and needs clear per-employee pricing or a written quote. It is not written for firms choosing payroll for clients, which is a different decision.

Red flags: you need co-employment and benefits in one PEO-style contract, your headcount changes sharply from month to month, or nobody on the team owns the month-end tie-out.

Decision checklist and common mistakes

Use this checklist before you request quotes:

• Write down headcount by month for the last 12 months, not just today.

• Confirm whether tax filing, year-end forms and multi-state filing are in the plan you are quoting.

• Ask for the all-in first-year cost: base fee, per-employee fee, add-ons, setup and any promotion end date.

• Confirm the provider syncs with your ledger and that the sync is included in your plan.

• Name the person who approves the monthly payroll-to-ledger tie-out.

Common mistakes to avoid:

• Comparing base fees and skipping per-employee fees, which dominate the monthly cost at firm headcounts.

• Treating an aggregator's price as the vendor's price. Sites in this check disagreed on QuickBooks, OnPay, Gusto and Justworks pricing.

• Assuming a promotion stays open. Paychex runs time-limited promotions, so check current terms.

• Ignoring the deposit schedule. The next-business-day rule can force deposits on short notice.

Questions firms ask before switching

Is there a Paychex alternative with published prices?

Yes, two of the five alternatives publish plan-level prices on pages we could open: QuickBooks Workforce Payroll and OnPay. Their published lines are per-month base fees plus per-employee fees, which makes a first-year estimate possible before any sales call.

Does the cheapest plan include tax filing?

Both pages that show plan prices describe tax filing as part of the plan, so the real question is what sits outside the base. Intuit's Simple Start line describes full-service payroll that calculates, files and pays payroll taxes, and OnPay's base plans list federal, state and local filings. Check year-end forms and any add-on fees in the written quote.

Does an accountant program matter for our own payroll?

Usually not, unless you also run payroll for clients. OnPay, Gusto and QuickBooks each describe accountant-facing terms, which price firms that bring clients to a provider. A 2015 CPA Practice Advisor column said firms can gain economies of scale once they have at least ten clients using their payroll services, according to CPA Practice Advisor (2015). That threshold is dated, so test it against today's offers.

How do the IRS deposit rules change the choice?

They make tax handling the first criterion, because the deposit schedule and the next-business-day rule decide how fast payroll money must move. Ask each provider who calculates, files and remits, and whether its deposit alerts reach the person who approves payroll.

Are Paychex promotions worth using?

It is worth using only if the payroll credit applies to the plan you need and you accept the one-year agreement. The Paychex page says the promotion covers the payroll component only, so setup and other fees still apply, and promotions are time-limited, so check current terms.

Where to go from here

Start with the figures you can verify today: Intuit's per-month lines, and OnPay's base and per-worker fees. Then request written quotes from Rippling, ADP and Paychex, and from Gusto once you can reach its current prices. Keep the month-end tie-out and the deposit alerts in your plan whichever provider you choose. For a configured version of that workflow, see how US Tech Automations configures this.
