Onward Gateway Software Consulting

Phuket-based programming consulting for merchants who need dependable connections between storefronts, ERPs, payment gateways, and fulfillment tools.

Review integration scope

Why teams in Thailand call us before replatforming

Cross-border checkout rules, Thai tax invoices, and warehouse cut-off times rarely fit a single plugin. We map how orders, refunds, and inventory events should move before anyone writes middleware.

Engagements stay scoped: discovery workshops, integration design, implementation pairing, or advisory sessions when your in-house developers own the code.

Recent work spans Shopify and WooCommerce hooks, custom REST bridges to legacy WMS tables, and webhook hardening when promotional spikes stress retry queues.

Commercial terms and hourly rates are agreed per statement of work; this site does not list fixed packages or guaranteed delivery dates.

Integration path from Thalang workshops to production traffic

A locality-led sequence we repeat for e-commerce systems integration engagements across Phuket and remote teams.

On-site or video discovery in ICT timezone

We document your current cart, OMS, and carrier labels from the 106/2 Thepkrasattri workspace or your office. Data owners name which fields are authoritative for SKU, bundle, and tax lines.

Contract tests before go-live weekends

Each external API gets fixture payloads, idempotency keys, and rollback notes. Staging mirrors production webhook secrets without copying customer PII.

Handover with runbooks your staff can follow

We leave sequence diagrams, alert thresholds, and a short advisory window so your team can extend integrations when catalogs change.

Where scoped projects usually focus

Network cables and hardware in a rack with network switches

Checkout and payment routing

3-D Secure flows, partial captures, and reconciliation files between PSP dashboards and accounting exports.

Catalog and PIM sync

Variant matrices, bundle explosions, and multilingual attributes pushed to storefront themes without manual CSV drift.

Fulfillment and returns

Carrier label APIs, RMA webhooks, and stock reservations when flash sales overlap with offline retail counts.

Questions merchants ask before signing an SOW

Do you resell platforms or take affiliate fees?

No. We bill time and materials or fixed-scope consulting tied to deliverables you approve. Platform subscriptions stay between you and the vendor.

Can you work with our existing agency?

Yes. We often pair with design partners: we own API contracts and observability while they handle theme UX, as long as roles are clear in the statement of work.

What if we only need a few advisory hours?

Short advisory sessions are available for architecture reviews or webhook incident post-mortems. Larger builds still run through scoped project engagements.
