The questions that separate providers - all askable before you sign
Payroll providers are easy to compare on price and hard to compare on whether the filings actually happen. These are the questions that produce different answers from different providers - and the answers a Lathrop buyer should insist on.
Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.
The IRS holds the employer responsible for depositing and reporting employment taxes even when payroll is outsourced, so a Lathrop owner who hires a provider is buying reliability and proof of filing - not a transfer of liability, which is the single most misunderstood fact in this market.
Payroll services quoted to Lathrop businesses in 2026 run $20-$150 a month in base fees plus $4-$15 per employee per month, which puts a ten-person Lathrop payroll at roughly $70-$250 a month before year-end filing and add-on charges.
Lathrop plus 10 surrounding communities within 40 km hold about 82,924 people, which is enough employer density that several payroll providers will quote the same account - the competition a single quote request is meant to create.
Payroll providers are easy to compare on price and hard to compare on the thing that matters - whether the filings actually happen, on time, in Missouri. The questions below are the ones that separate providers, and every one of them can be asked before you sign anything.
The payroll market runs from twenty-dollar software to full-service outsourcing, and the middle of it is crowded with lookalike offers. For a Lathrop business the deciding questions are narrow: who signs the returns, who pays the penalty if a deposit is late, what happens to your data if you leave, and how the price changes at renewal.

The four ways to buy payroll, compared
| Type | 2026 cost shape | Who signs and files | Fits |
|---|---|---|---|
| Payroll software | $20-$150/mo plus per employee | You do - the software prepares, you remain the filer | One state, stable staff, an owner who tracks deadlines |
| Full-service payroll | $70-$250/mo at 10 employees | The provider files as your agent; the IRS still holds you responsible | Most small employers, especially with hourly staff or turnover |
| PEO / co-employment | $30-$100/person/mo or a share of gross payroll | The PEO reports under its own arrangement - terms vary, read them | Employers buying benefits and HR alongside payroll |
| Bookkeeper or CPA firm | Hourly or monthly retainer | The firm prepares and files on your behalf | Businesses already paying for accounting and wanting one relationship |
Verify before any signature
- Ask which returns the provider signs and files: Form 941 quarterly, Form 940 annually, Missouri withholding and unemployment wage reports
- Ask for sample filing confirmations from a recent client month - on-time filers produce them without hesitation
- Confirm whether the provider is a reporting agent, a certified professional employer organization, or software only - the liability differs and the IRS publishes the distinction
- Confirm the error policy in writing: who pays interest and penalties on a provider-caused late deposit, and up to what limit
- Check that the provider registers you correctly in every state where you have an employee, including new states mid-year
- Confirm data portability: full payroll history export in a usable format, at any time, at no charge
- Verify the renewal price and the notice window required to cancel, then calendar the notice date the day you sign
Walk away when you see
- A quote that shows a base fee but will not put the all-in monthly total at your headcount in writing
- 'Tax filing included' with no statement of who pays the penalty when a deposit is late
- Refusal to provide filing confirmations - EFTPS receipts and state e-file acknowledgements - on request
- An introductory rate with no written renewal price, or an auto-renewal clause with a short notice window
- Per-employee pricing that keeps billing for terminated employees through the end of the year
- No named contact for tax notices, or a support model that routes IRS correspondence back to you unhandled
- Export restrictions on your own payroll history if you leave - your records should follow you
- A provider that cannot say which Missouri filings it makes on your behalf and which stay with you
What a payroll quote should include - and what the padded version sells
A complete quote includes
- The all-in monthly total at your real headcount, not just the base fee
- Full-service tax filing and deposits stated as included, with the returns named
- Year-end W-2 and 1099 filing priced, or explicitly included
- Every state you employ someone in, registered and filed for
- A written error policy: who pays penalties and interest on a provider-caused late deposit
- The renewal price and the cancellation notice window, in writing
Red flags in a payroll proposal
- A headline price that excludes tax filing, sold back as an add-on
- Per-employee billing that continues for terminated employees
- 'Compliance guaranteed' with no named returns and no penalty policy
- Refusal to show filing confirmations for a sample client month
- An introductory rate with an unstated renewal price
- Payroll history you cannot export in full if you leave
The one request that tells you everything
Ask any provider for EFTPS confirmations and state e-file acknowledgements from a recent client month, with client details redacted. Providers that file on time produce them without hesitation, because the confirmations already exist. The ones that hesitate are telling a Lathrop buyer something no pricing page will.
What this means in Lathrop
A late deposit costs 2% to 15% of the deposit; a full year of payroll processing for a small Lathrop employer costs less than one such penalty on a modest payroll. Price the service second and the failure mode first.

Common questions
What do I need to give a payroll company to get a quote?
Employee count split into salaried, hourly and contractors; every state where someone physically works; pay frequency; expected off-cycle runs; and whether you need benefits, time tracking, garnishments or workers' comp integration. Providing all of it up front is what makes competing quotes genuinely comparable - and it is exactly what a marketplace form collects once and sends to several providers.
What hidden fees do payroll companies charge?
The recurring surprises are year-end W-2 and 1099 filing at roughly 4-8 dollars per form, additional state tax filings at 6-20 dollars per state per month for remote employees, off-cycle or bonus runs at 5-50 dollars each, setup or implementation fees, charges for mailed paper checks, and per-employee fees that continue for terminated staff. Ask for the full fee schedule in writing, not the pricing page.
Can I do payroll myself instead?
Yes, and for a single-state business with a handful of salaried employees, software plus discipline is genuinely cheaper. The variables that change the answer are multi-state employees, hourly overtime, tipped wages, garnishments and turnover - each multiplies the number of deadlines. For scale, an in-house payroll specialist averages about $64,865 dollars a year in 2026 wage data, so the real comparison for most small employers is software plus your own hours versus a service.
How much does a payroll service cost for a small business?
In 2026 published pricing, payroll services charge a monthly base fee of roughly $20-$150 dollars plus $4-$15 dollars per employee per month. A ten-employee business commonly lands between $70 and $250 dollars a month before add-ons. Full outsourced processing is often quoted per person instead, at roughly $30-$100 dollars per employee per month. These are directional market ranges, not quotes.
When does a final paycheck have to be paid?
That is set by state law, and it differs for employees who are fired versus employees who quit. Several states require immediate payment on termination; others allow the next regular payday; a few add a penalty that accrues per day until the check is delivered. Unused vacation payout is likewise state-specific. The rule for Missouri is on this site's final-paycheck page with its source.
