Real briefs · real targets

From our BC engagements — where a project is not yet live, the numbers are targets set with the client.

Multi-branch Retail

Multi-branch retailer · NE Thailand

Go-Live Q3 2026

Challenge

Legacy MAC-5 + Excel + three-person accounting · month-close taking 15 days · stock invisible across branches · needed to open new branches without hiring more accounting headcount.

What we did

BC + WJ Connect Portal, module-first rollout: Sales/Purchasing first, Advanced Warehouse and Loyalty deferred to a later phase, full Thai localization included.

Outcome

Go-Live 03/08/2026 · real-time stock across every branch on executive mobile · target month-close 5 days · handover clean, internal team runs it.

Financial Services (Regulated)

Regulated financial-sector organization(NDA)

1+ year live

Challenge

SAP quote out of budget · must pass regulatory and two external audits per year · audit trail, SoD, and Thai localization needed from day one, not retrofitted.

What we did

BC + WJ Connect Portal with native SoD and audit trail configured from week 1 · full Thai Localization pack · delivered with Clicknext as partner.

Outcome

Passed regulatory and external audits · no major IT-control findings · MA renewed for multiple years · estimated TCO ~30% of the SAP quote (like-for-like scope).

Field Service (AFSM)

Field-service business

In build / proposal 2026

Challenge

Repair work spread across many sites · work orders and dispatch still on paper and Excel · technicians can't update status in time · parts and assets drift out of sync with BC.

What we did

SmartFix on Business Central — full work-order lifecycle · technician dispatch with AI-assisted ranking · on-site mobile status updates · parts and assets posted back into BC automatically.

Outcome

Target: digital work orders end-to-end · real-time technician updates from mobile · managers see every job's status · every document posts into BC with no re-keying.

Questions clients ask before deciding

Straight answers, no dodging. If yours isn't here, email us.

Is BC too expensive compared to SAP B1 or other options?+
BC license runs ~$80/user/month · you only need 3 power-user seats for a 30-person org (everyone else uses WJ Connect Portal) · 5-year TCO is ~40-60% of SAP B1 when delivered by WJCT.
Can the internal team actually use it? How long is the learning curve?+
The portal is designed for regular users to learn in 1-2 hours · power users need 1-2 weeks on BC · we ship full video training for every workflow · WJCT handles handover until the team runs it in production, not just up to go-live.
How long does a project take? What if the timeline slips?+
SME package: 90-120 days · Enterprise: 6-12 months · we use module-first (one workstream at a time) to minimize risk · slippage from scope creep gets split into quick-win vs long-term fix · slippage on our side is covered under the contract at no extra cost.
What if WJCT shuts down? How does handover work?+
Every project ships with a handover package: source code (AL extension) · documentation · video training · configuration export · WJ Connect Portal is open source, so your internal team or another SI can maintain it right away · no lock-in.
Who owns the data? Can I switch to another SI later?+
You own all data · everything runs on your BC tenant, not ours · the portal can be deployed on your own infrastructure · standard-format export is available at any time · exit clause is explicit in the contract.
