Offer payroll on your platform, under your brand.
Clevis calculates and pays payroll in six LatAm countries behind the scenes. Your clients only see your product, and every number comes with its formula and the law behind it.

What the engine calculates, country by country
Product
Payroll you can check, explain and defend.
Clevis is the calculation engine behind your payroll product. You get the control of owning the engine, without building it, hiring a payroll team, or chasing law changes in every country.
An audit trail on every calculation
Each line shows the formula, the inputs it used, the result before and after rounding, and the rounding rule. When the authority asks where a number came from, your client has the answer.
Law changes handled, past payslips intact
Rule sets are versioned by country, year and scheme. When the law changes, we publish a new version — and last month's calculations still reproduce exactly. No change requests on your side.
Each country, done properly
Mexico's ISR and IMSS. Colombia's overtime and night surcharges. Peru's annualized 5th-category tax. Six countries, each modeled on its own law, behind one integration.
Under your brand
Clevis has no UI and never appears in front of your clients. You own the payroll experience; we run the engine behind it.
Calculate, then pay
Send the net to the employee's local bank account straight from the calculation — same API key, same JSON shape.
Numbers that add up to the cent
Amounts come back as exact decimal strings, never floats. Two biweekly periods add up to the month, on every line.
Integration
Calculate, then pay. Same key, same integration.
Four steps from employee data to a paid payroll. Every calculation comes back with its reasoning attached, so your client can answer the authority line by line.
Authenticate
One API key, Bearer auth. No SDK to ship to production.
Send the payroll inputs
Salary, period, country and scheme — plus the overtime and allowances your platform already captures. JSON in, JSON out.
Get a defensible result
Net pay, earnings, deductions and employer contributions — every line with the formula that produced it and the caps applied, pinned to the rule-set version it used.
Pay the employee
POST the net to /v1/payouts with the employee's local bank account. Idempotent requests, signed webhooks on every status change.
API surface
A small API. On purpose.
Calculate, batch, simulate, then pay — one Bearer key and the same JSON shape in every country. Your engineers learn it once; each country's law lives in the rule sets, not in your code.

Build it, buy a payroll provider, or embed Clevis.
The honest comparison. Most platforms find out their provider is a black box the day a client has to justify a number to the authority.
Who it's for
For platforms that need to offer payroll, not build it.
HR and workforce suites entering new countries
You already run attendance, pre-payroll or payroll at home. Clevis covers payroll in each new country, so your answer is never “everything except payroll.”

Vertical SaaS

Company
Built by people who've shipped payroll at scale.
There's no such thing as “LatAm payroll.” There's Mexico's, Colombia's, Brazil's — each tied to its own tax and social security law. Clevis models each country on its own terms and hands back the reasoning behind every number, so your clients are never left defending a figure they can't explain.
