Frequently Asked Questions
If an off-the-shelf app truly fits, we recommend it. We build custom when you need exact rules, reliability at scale, faster pages, data ownership, or lower long-term cost than stacking multiple plugins.
No. Performance is non-negotiable. We load code only where needed, use edge caching, and enforce performance budgets. Most clients are faster post-consolidation than with many plugins.
We release behind feature flags, run live-shadow tests, and keep a one-click rollback. If anything looks off, we revert instantly—no downtime.
We keep you out of scope where possible (tokenized payments), implement 3-D Secure correctly, and surface clear error handling to reduce false declines. We’ll also document any obligations on your side.
Our SLA support tracks deprecations and rolls out updates early. You’ll get release notes and test windows—no surprises.
Before building, we agree on one or two target metrics—like conversion rate (CVR), average order value (AOV), repeat purchases, or support time saved. After launch, you get a dashboard to track these KPIs, and we iterate on features if they don’t hit the targets.
