What we've actually built

Screenshots of systems we built ourselves on Business Central (shown with demo data) — see every module on the products page.

Why WJ Connect

Built on Business Central

An ERP used by 40,000+ organizations worldwide · meets Thai Revenue Department e-Tax and bookkeeping standards.

Pay only for the licenses you need

We match each person to the right license — people who only view or approve get a low-cost license instead of a full one.

Thai localization included

VAT · Withholding tax · Thai tax invoice ready from BC out of the box · e-Tax via INET or a certified provider.

One step at a time

Start with the modules you need · add more as you grow · no need to switch everything at once.

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

In progress

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

Targets: real-time stock across every branch on the owner's phone · month-close in 5 days · the internal team runs it on its own.

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).

From your ideato an app that posts into Business Central

Three steps — you bring the brief, we handle the rest.

Step 1

Tell us your idea

Describe what you want the system to do — workflows, reports, what your team needs daily. Send it to our team.

Step 2

We map it to Business Central

We wire the data and logic to the BC you already run — no need to rebuild your structure.

Step 3

Build the app · post back to BC

You get an app your team actually uses; data flows back into BC automatically — work carries on as before.

Your datastays on your Business Central

Runs on your own BC

Data lives in your BC, not ours · connected through Microsoft's standard API, never by modifying BC's core code.

Full Thai tax localization

VAT · withholding tax · e-Tax Invoice & e-Receipt · every entry traceable · the person who records is never the one who approves.

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 licenses are paid to Microsoft at ~$80/user/month (Essentials) · people who only view data or approve use a much cheaper license (Team Member, ~$8) · anyone who creates or changes data in BC needs a license that fits their work, even when they do it through our web app — we help you match each person to the right license, so you don't overpay and stay within Microsoft's rules · A real example: a financial-sector client estimated its total cost of ownership (TCO) at ~30% of the SAP quote for the same scope.
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?+
Standard package (core modules, no extra customization): 6–8 weeks · full project: 90–120 days · Enterprise: 6–12 months · we go live one workstream at a time to minimize risk · slippage from added scope gets split into quick wins vs long-term fixes · slippage on our side is covered under the contract at no extra cost.
What if WJCT shuts down? How does handover work?+
All your data stays in your own Business Central, not with us · every project ships with a handover package: documentation · video training · configuration export · the BC extension and web app installed in your system — the source code stays with WJCT and is not part of the handover.
Who owns the data? Where does the web app run? Can I switch to another partner later?+
You own all data · everything runs on your BC tenant, not ours · the web app can run on your own server or cloud (our retail client runs it on its own server) · standard-format export is available at any time · the exit clause is explicit in the contract.
What is Business Central (BC)? Can you help if we don’t have it yet?+
BC is Microsoft's all-in-one accounting, inventory, purchasing and sales system, used in a web browser with no server to run yourself · if you're still on Excel or an accounting package, we set BC up from scratch · if you already have BC, we build web apps your team finds easy that feed straight into it.
Microsoft updates BC twice a year. Will the web app break, and who fixes it?+
Our web apps talk to BC through Microsoft's standard API and never modify BC's core code, so updates rarely break them · for clients on a monthly care plan, we test against each new version before it goes live and fix anything within the plan.
