Question 1

When does it make sense to build a custom split engine?

Accepted Answer

Building makes sense if you need proprietary split logic beyond Ocuula's 5 presets and routing rules, have existing payment infrastructure with significant investment, or your compliance requirements strictly prohibit third-party integrations. For most teams, the 2-4 week build time plus ongoing maintenance is significantly more expensive than Ocuula's per-transaction fee.

Question 2

How long does it take to integrate Ocuula vs building from scratch?

Accepted Answer

Ocuula integration typically takes hours, not weeks. The REST API has 5 endpoints covering splits, batch operations, provisioning, and transaction queries. Sandbox access is instant with unlimited free transactions. Building from scratch requires 2-4 weeks for basic functionality, plus ongoing work for edge cases, retry logic, and compliance.

Question 3

What ongoing maintenance is required for a custom split engine?

Accepted Answer

Custom split engines require dedicated engineering time for: bug fixes and edge case handling, compliance updates (audit trails, data retention), API maintenance and documentation, Moolre integration testing whenever the payment processor updates their APIs, and scaling infrastructure as volume grows. Ocuula handles all of this as part of the per-transaction fee.

Question 4

Can I migrate from a custom solution to Ocuula later?

Accepted Answer

Yes. Ocuula's API is designed for incremental adoption. You can route a subset of transactions through Ocuula while keeping your existing system running in parallel. Routing rules make it straightforward to shift volume gradually — by merchant, transaction type, or amount bracket.
