01

One platform
for the entire welfare cycle.

Appaga manages the full corporate welfare lifecycle: from issuing credits to multi-channel spending, from e-invoicing to reporting, all the way to local donations and loyalty programs for employees and shops.

02

Where we
started.

HR running welfare on Excel and email. Fifteen different providers, each with its own export format. SDI invoicing rebuilt by hand, local donations tracked on parallel spreadsheets. A corporate program, a cottage-industry process.

i.

The challenge

Unify welfare management across 15+ heterogeneous providers — meal vouchers, training, healthcare, mobility — under one platform. SDI e-invoicing generated natively from the flow. Local donations tracked in a compliant way. Five different actors (HR, employee, provider, merchant, municipality), each with its own view.

ii.

Our approach

One platform with a standardized integration for each provider — each one speaks its own language, we translate behind a single API. SDI generated automatically from the issuance flow, not as a follow-up step. Five views, one underlying economy: the same voucher moves through company, employee, shop, invoice and report without ever changing identity.

iii.

The result

A unified welfare cycle from issuance to tax reporting. Automatic reconciliation with 15+ providers, native e-invoicing via SDI, a clear cut in HR workload. The same system manages meal vouchers, Appaga vouchers and local donations — the same experience for the people who configure it, different rules under the hood.

03

Five steps,
from credit to report.

The same flow covers Appaga vouchers, meal vouchers, gift cards, travel, reimbursements and meal networks — only the provider underneath changes.

01

Issuance

Employee CSV upload, validation, invoicing, digital voucher creation.

02

Spending

Multi-channel: vouchers, meal vouchers, gift cards, travel, reimbursements, meal networks.

03

Invoicing

Welfare SDI via Qonto, merchant self-invoices, SEPA transfers.

04

Reconciliation

Automatic matching between receipts, redeemed vouchers and issued invoices.

05

Reporting

Audit trail, accounting exports, tracked local donations.

04

One console
for the people who configure it.

Budget, SDI invoicing, providers, employees and tax reporting — a single view for the HR team running the plan, no jumping between tools. 340 active employees, € 487,200 in budget issued YTD, 15+ providers integrated.
