## Why teams choose Certino

From raw compensation data to payroll-ready figures, with every number explained. Global payroll runs on control, not guesswork.

- **Data checked before it's calculated.** Certino collects pay, benefits and expenses from your existing sources and flags gaps and errors before they reach a calculation or a payslip.
- **Same inputs, same answer, every time.** Every result uses fixed rules and up-to-date logic. That covers regional taxes, social security and local payroll methods, so figures are easy to review, explain and audit.
- **Works with what you already have.** Certino sits upstream of your current payroll, tax and HR providers. You don't need to move systems, and your established processes stay as they are.
- **Use it directly, or power your own service.** Run Certino in-house, or build it into your own offering. Partners get one trusted calculation layer across every client and country.

## How Certino fits into the payroll process

Certino sits between your data and your delivery. It takes pay, benefits and expenses from the systems you already use and hands payroll-ready figures to everyone downstream, with actuals reconciled at year end.

### Shadow payroll you can check, explain and trust

[Shadow payroll](https://www.certino.com/shadow-payroll?hsLang=en) is complex by nature: multiple countries, changing tax rules, gross-ups, hypo tax and tight deadlines. Certino brings it under control.

- **One source of truth for global comp.** Scattered HR, payroll and expense data is centralised and checked well before payroll cut-off.
- **Every number shows its workings.** See exactly how each figure was reached, so reviews, employee queries and audits are quick.
- **Gross-ups done properly.** Regional taxes, social security, local payroll methods and your company policy are all built into every calculation.
- **An annual true-up, not an annual scramble.** Actuals are reconciled against what was reported, then recalculated.
- **Works with your existing providers.** Certino sits upstream of your advisers and payroll providers, with no system changes.

### The calculation layer behind your expat payroll service

Certino gives tax, payroll and mobility providers one platform to centralise client data, run every cross-border calculation, and deliver payroll-ready figures in any country. It's your service and your brand, running on our engine.

- **Every client's data in one place.** Pay, benefits and expenses come together from the systems your clients already use, and are checked before anything is calculated.
- **One set of rules for every client.** The same inputs give the same answer, whoever runs it and wherever. You stop rebuilding country logic in spreadsheets.
- **Year-end true-ups built in.** Reconcile actuals against what was reported and recalculate, without a separate project every year.
- **You keep the client.** Use our platform, or build Certino into yours. We stay in the background.

## What makes Certino different

![certino-different-engine-wide](https://www.certino.com/hubfs/certino-different-engine-wide.png)

### A specialist engine, not a bolt-on

- **Built for cross-border pay from day one**  
  Hypo tax, gross-ups, shadow payroll and true-ups are the core product. They aren't add-ons to a domestic payroll system or a general tax tool.
- **One right answer, every time**  
  Certino's logic is deterministic. There are no judgement calls hidden, and results don't drift between teams, advisers or countries.
- **Rules updated once, used everywhere**  
  When tax rules change, they're updated centrally in the engine. Every calculation for every client uses the latest logic.

![certino-different-scale-wide](https://www.certino.com/hubfs/certino-different-scale-wide.png)

### Built to run every month, at scale

- **Scale, not heroics**  
  Monthly runs don't depend on one expert, manual fixes or late nights before cut-off. Adding countries or assignees doesn't add chaos.
- **A layer, not a replacement**  
  Certino sits upstream of payroll and tax delivery. Your advisers and payroll providers stay exactly where they are.
- **Built to power firms, not compete with them**  
  Tax, payroll and mobility providers use Certino behind their own service. We never go after their clients.

> We work on a country-by-country basis, so delivering a single report in the Certino system and immediately providing shadow payroll results was very advantageous to us. This combination of benefits makes Certino unique as a shadow payroll provider.
