Why it matters

Why integrations from WPExperts keep working

  • Built on official APIs with authentication, rate-limit handling and retries
  • Every sync logged and monitored, with alerts when something needs attention
  • Idempotent by design — reruns never create duplicate orders or records
  • Documented mappings so your team knows exactly what moves where
  • Load-tested against real catalogue and order volumes
  • Marketplace-grade code quality from the team behind 120+ published plugins

Manual re-keying between systems is where errors, delays and lost orders come from. Our WordPress experts build integrations that move products, orders, customers, inventory and content between WordPress, WooCommerce and the rest of your stack automatically — with logging, retries and alerts so nothing silently fails.

Integration work we do most often

Daily stock and price syncs from supplier APIs into WooCommerce, order export to ERPs and 3PLs, customer and lead sync to CRMs, multi-vendor payouts through Stripe Connect, and custom endpoints for mobile apps. If it has an API, it can talk to WordPress — the difference is whether it still works in a year. Ours does.

How we work

From brief to launch in four steps

Discovery

A short call or written brief. We map the real requirement, not the assumed one.

Written plan & estimate

Scope, milestones, fixed price and the risks we see — before anything is built.

Build in the open

Staging access, weekly demos and coding-standards compliant PHP you can read.

Launch & support

Deployment, monitoring and a warranty window. Then optional retained support.

FAQ

Questions before you get in touch

Our supplier only provides a CSV or FTP feed — can you still integrate it?

Yes. We build scheduled importers with validation, change detection and reporting for feeds of any format, including large catalogues.

What happens when the API is down?

Requests are queued and retried, failures are logged, and you are alerted if a sync does not complete — no silent gaps.

Can you integrate with a system you have not seen before?

If it has documentation, yes. We scope the mapping first, confirm the edge cases with you and build against a sandbox before touching production.
