How to Choose a Payroll Outsourcing Company?

How to Choose a Payroll Outsourcing Company?

Make your choice by comparing evidence across six areas: technical capabilities regarding your payment rules, division of responsibilities, team continuity, data security, platform traceability, and exit conditions.

Price matters, but comparing prices only makes sense when the scope of services is equivalent. A low rate that excludes rework, final settlements, or reports may end up costing more than a higher, all-inclusive rate. A practical selection method consists of four steps:

1. Review our own processes: staffing, types of contracts, variable compensation, branch offices, current systems, and areas where errors currently occur.
2. Send the same request for proposals to each supplier: this way, the responses can be compared without having to translate proposals in different formats.
3. Try using anonymized real-life cases: ask them to solve challenging situations from your operations and explain their reasoning.
4. Check before signing: call references, review the contract with legal counsel, and get to know the people who will be handling the account.

Which criteria should carry the most weight in the decision?

Greater weight should be given to criteria whose outcome directly affects employees or the company: technical accuracy, compliance, continuity, and information security.

This table serves as an evaluation guideline. The priority listed is a suggestion and should be tailored to each company: a company with shifts and commissions will place greater emphasis on technical skills, while a subsidiary of a multinational corporation may prioritize reporting and controls.

What questions should you ask the vendor before signing a contract?

The best questions require you to describe a specific procedure: who does what, with what oversight, within what agreed-upon timeframe, and what happens when something goes wrong.

Group them by topic so the meeting doesn't turn into a sales pitch.

About the Monthly Transaction

• Who will calculate our pay, and who will review it before the process is finalized?
• What are your proposed deadlines, and what happens if a new development is reported after the deadline?
• How do you handle an urgent, unscheduled payment, such as a severance payment?
• What checks do you perform from one month to the next to detect anomalous variations?

On Mistakes and Responsibility

• How is an error classified, and what is the timeframe for correcting it?
• Who is responsible for adjustments, interest, or penalties if the issue stemmed from a calculation error by the supplier?
• Is there a liability limit in the contract or professional liability insurance? What is the coverage?

About Data and Access

• Who can view salaries within your organization, and where is that access logged?
• Do you outsource any part of the process or infrastructure?
• How are you preparing for Law 21,719 on the protection of personal data?

On Changes and Departure

• What happens to the price if the allocation increases or decreases?
• Which calculation rule changes are included, and which ones are priced separately?
• Upon completion, what files do you deliver, in what format, and with what version history?

How can you test a vendor using real-world scenarios?

Give them a set of anonymized cases from your own operations and ask them to calculate and explain them: that way, you can assess their technical expertise without relying on sales pitches.

Remove names, tax ID numbers, and any other identifying information before submitting the material. Select situations that have raised questions within your company, for example:

• An employee on commission with a rolling workweek who was on partial sick leave for one month.
• A change in the work schedule midway through the month, and its impact on the overtime rate.
• An annual bonus paid in a single month to a high-income individual, including its tax implications.
• Severance pay including prorated vacation pay and variable compensation.
• Mid-month payment with discounts for child support or social credit.

When reviewing the responses, look for three things. First, whether the vendor asked what was missing instead of assuming it—because that attitude often foreshadows how they’ll work each month. Second, whether they can explain the logic to management without resorting to technical jargon. Third, whether they honestly point out any debatable issues or those requiring legal judgment, rather than presenting everything as a certainty. A result that differs from yours doesn’t necessarily mean the vendor is wrong—sometimes it reveals an error your company had been carrying forward.

What should be included in the contract?

The exact scope, service levels, allocation of liability for errors, confidentiality and data rules, and the terms for termination and return of information must be set forth in writing.

• Scope: number and type of processes, documents, employees, companies, and reports included.
• Calendar: deadlines, payroll submission, approval, payment, and tax filings, with the individuals responsible for each stage.
• Service levels: response and resolution times by incident type, as well as a way to measure them.
• Errors: How to determine their source, who corrects them, and how surcharges are handled. Pay special attention to the liability limits.
• Personal Data: Purpose of Processing, Security Measures, Incident Notification, Use by Third Parties, and Deletion or Return Upon Termination.
• Confidentiality: an obligation for the supplier and its team that remains in effect after the contract ends.
• Price: adjustment variables, additional costs, and conditions related to increases or decreases in staffing levels.
• Output: notice of completion, deliverables, data format, and collaboration with the next vendor.

Law 20.123 on subcontracting also warrants review. Depending on how the service is provided, it’s a good idea to consult with an attorney to determine whether the subcontracting regulations apply to the supplier’s staff and what labor and social security compliance certificates to request. This is distinct from the salaries of your own employees, which remain the responsibility of your company.

How can you compare quotes that are so different from one another?

They are compared by standardizing them to the same scenario: the same funding, the same annual processes, and a common list of included and excluded services.

Define a typical year for your company—including how many pay periods, severance payments, final pay calculations, and special reports you expect—and ask each provider to quote a price based on that. This will reveal the differences that a monthly fee hides: a per-pay-period charge may be cost-effective with a stable workforce but become more expensive with high turnover, while a flat rate may have caps or exclusions.

Also factor in the initial costs, such as data migration and configuration, as well as the costs associated with switching providers down the line. This article on the cost of outsourcing payroll processing details pricing factors, and this guide to payroll outsourcing in Chile provides context if this is your first time hiring a provider.

What red flags should make you rule out a vendor?

The main ones are empty promises, the refusal to reveal the actual platform, the failure to address errors, and the lack of clear exit conditions.

• Zero-error guarantees. Any process involving human data is prone to error, so what’s worth evaluating is how errors are detected and corrected.
• Figures without a source. Percentages for savings or error reductions should be backed by verifiable evidence. If there is none, do not use them to justify the decision.
• References that are impossible to contact. A provider may protect its customers' identities, but it should offer some reasonable way to verify their experience.
• A sales representative who has no contact with the team. If you never meet the person who will be managing your account during the evaluation, you won't know who you'll actually be working with.
• Careless handling of information even at the sales stage. If they ask you for pay stubs with actual data that isn't protected for the purpose of calculating contributions, it's reasonable to assume they'll treat your information the same way during the service period.

How can you check references effectively?

Ask to speak with clients of similar size and complexity, and ask them about specific incidents rather than seeking a general opinion.

General questions tend to elicit polite but uninformative answers. These work better:

1. What was the most serious mistake you've ever made, and how did the vendor handle it?
2. What was the first actual lockdown like, and what would you change about how it was implemented?
3. Has the team serving you changed? Did you notice a difference in the service?
4. What tasks did you think were included but ended up doing yourselves or paying for separately?
5. Given what you know now, would you hire him again for the same scope of work?

Pair your conversation with what the vendor posts. If you compare their proposal with other options—such as payroll software—you’ll also be able to see whether they’re recommending what’s best for you or just what they’re selling.

How does Wiseplan measure up against these criteria?

Wiseplan offers a payroll calculation and payment service that includes document management, online access, a self-service portal, strategic reports, and confidential management of private payroll data.

According to its website, the company has more than 12 years of experience and a team with a proven track record in consulting, human resources, labor law, and organizational psychology. It also offers attendance tracking using biometric technology, as well as legal advice and representation in labor disputes. None of this replaces the evaluation described in this article: the same guidelines can and should be applied to Wiseplan, using real-world scenarios, questions about the contract, and a conversation with the team that would handle the account.

Frequently asked questions

How many suppliers should you evaluate?

There is no "right" number, but it's a good idea to compare enough candidates to evaluate different approaches without dragging out the process too long. A short shortlist allows you to devote real time to test cases, references, and the contract—which is where the differences become apparent.

Is it better to choose a specialized provider or one that offers a full range of HR services?

It depends on your needs. If you’re only looking for payroll processing and have an in-house team, an operational specialization may be sufficient. If you also need HR consulting, recruitment, or external management, having everything coordinated can be helpful—as long as you verify who is providing each service.

Should I require the supplier to be familiar with my industry?

This is recommended when your business has specific working days, shifts, or bonuses. The most reliable way to verify this is through test cases, since a list of clients in the industry does not guarantee that the person managing your account is familiar with those rules.

Can the contractor assume the employer's legal liability?

Not with respect to the employees, because your company remains the employer. The contract can specify which costs the supplier is responsible for when the problem stems from an error on the supplier’s part, and this point should be reviewed with legal counsel.

What information can I provide during the evaluation?

Aggregated data and anonymized cases are sufficient: headcount, contract types, variable compensation, and number of companies. Avoid sending payroll records that include names, tax ID numbers, or actual salaries before you have a confidentiality agreement and a contract with data rules in place.

What happens if I'm not satisfied after signing the contract?

It all depends on what was agreed upon regarding notice of termination, deliverables, and data format. That is why the exit process should be negotiated at the outset. It is also a good idea to keep regular backups of critical information, such as pay stubs, contracts, and vacation balances.

If you'd like to apply this guideline to your company, you can contact the Wiseplan team and request a proposal based on your actual staffing levels and payment terms.
