Key differences

No sandbox in Oblio

Oblio does not provide a sandbox environment. This means every integration test you run hits the real production API and risks creating real invoices or consuming real quota. Billyou provides a free sandbox with 10,000 test invoices, completely isolated from production, where you can safely test every scenario including error cases.

No webhooks in Oblio

Oblio has no webhook support. To know when an invoice is confirmed in SPV, you need to poll the API repeatedly. Billyou fires real-time webhook events for every state change, allowing you to build reactive integrations that respond instantly to ANAF confirmations or rejections.

No official SDKs

Oblio does not publish official SDK libraries. Developers must construct raw HTTP requests and handle all response parsing themselves. Billyou provides first-party SDKs for Node.js, Python and PHP with TypeScript types, automatic retry on transient errors and built-in webhook signature verification.

Pricing predictability

Oblio combines a monthly fee with per-invoice charges, making costs hard to predict as volume grows. Billyou uses a flat subscription model: one price regardless of how many invoices you send. This is much simpler to budget for when building SaaS products or marketplaces.
