ERP integration ERP integration and custom development Keep your ERP,
and add what it is missing.

Packaged ERPs such as Digiwin or SAP Business One handle accounting and inventory well, but some workflows, reports and system connections are always out of reach. If your ERP still works, we add the missing piece beside it and connect it to e-commerce, POS, warehouse and member systems through APIs. If your processes are your competitive edge and no packaged ERP fits, we build the whole ERP around your operations.

We already have an ERP. Why would we need integration or custom development?

Packaged ERPs are strong at standard processes such as accounting, inventory and purchasing. Workflows unique to each company, such as quotations, dispatch, quality checks, distributors or online orders, are often patched with spreadsheets and re-typing. ERP integration lets the ERP exchange data automatically with other systems under clear data ownership; custom development adds the missing module beside it. In most cases the ERP does not need replacing, since replacement costs and risks are usually far higher than extending it.

Real projects ERP and integration work we have done

Extending, connecting, building from scratch: we have done all three.

These are projects we actually developed, from adjusting reports in an existing ERP to building whole systems from scratch for logistics, semiconductor, insurance and fitness businesses.

2026Manufacturer

SAP Business One report changes

The existing SAP Business One stayed in place; we adjusted only the reports the floor needed, so the ERP stays in use.

  • Keep the ERP
  • Reports
  • Manufacturing

Since 2020Asialife

Omnichannel retail POS and accounting handoff

Before development we worked through tax rules and accounting handoffs item by item. Since launch it has run stably through more than one million transactions (shared by the client), and we have added multi-rate tax, a distributor model, bank payment collection and external APIs.

  • Accounting handoff
  • External API

2026Apparel brand

Custom ERP built around operations

Off-the-shelf ERPs did not fit, so we are custom-building an ERP around the brand's own operations.

What we do What ERP integration and custom work cover

Your ERP stays. We fill the gaps.

We first check which interfaces your ERP exposes, then decide whether to add a module, build an integration or only adjust reports.

01 MODULE

Workflows your ERP lacks

Quotations, dispatch, quality checks, repairs or distributor orders become separate modules that write back to the ERP.

02 COMMERCE

E-commerce and POS to ERP

Orders, products, inventory and invoices sync automatically, with no more exporting spreadsheets and importing them into the ERP.

03 WAREHOUSE

Warehouse and logistics

Picking, shipping, delivery and proof of receipt flow back to the ERP, so inventory figures come from one source.

04 REPORT

Reports and dashboards

When built-in ERP reports do not fit, we read ERP data directly into new reports without touching the accounting.

05 SME

Inventory systems for SMEs

No ERP yet and packaged ones do not fit? Start with an inventory and order system that is just enough, with interfaces ready for accounting later.

06 TAKEOVER

Taking over custom systems

Peripheral systems whose vendor is gone and documents are incomplete are stabilised first, then kept, upgraded or replaced.

Buy, build or connect Replace, extend or build

Packaged ERP, keep and extend, or fully custom ERP?

Most companies do not need a full rebuild. It depends on how standard your processes are and where a packaged ERP breaks when customised.

ApproachBest forWatch out for
Packaged ERPAccounting, inventory and purchasing that look like most companies'Heavy customisation is costly and may need redoing on upgrades
Keep the ERP and extend itThe ERP works but lacks a few workflows, reports or connectionsConfirm the ERP's interfaces (API, database, file exchange) and licensing first
Fully custom ERPYour processes are your edge and no package fitsRequirements take the longest; launch in phases and run old and new in parallel

Process How we work

Map how data moves before writing code.

Integration projects stall on field definitions and data ownership more than on code. We settle those first, and every phase ends with something you can accept.

  1. STEP 01

    Systems and workflows

    2–4 weeks

    List the ERP version and its interfaces, the systems to connect and who owns each field, and mark where data is re-typed most.

  2. STEP 02

    Spec and prototype

    Depends on scope

    Write the API contract, field mapping, sync frequency and failure handling. Screens are prototyped and tried by staff before sign-off.

  3. STEP 03

    Phased build and testing

    3–8 months

    Launch the most painful piece first and test reconciliation with real data. Run old and new in parallel before switching.

  4. STEP 04

    Operations and extension

    Ongoing

    Monitor sync failures and data differences, and adjust when the ERP is upgraded or processes change. The same team stays responsible.

Pricing Price ranges

How much do ERP integration and custom development cost?

Estimates for custom projects in Taiwan in 2026. The final figure depends on the number of systems, how open the ERP is and how complex data conversion is.

FAQ Common questions

ERP integration FAQ

We use Digiwin or another packaged ERP. Can you integrate with it?

Most packaged ERPs offer an API, database views or file import and export, but what is open depends on the version and licence. We first confirm your ERP version and available interfaces, then choose the approach; some interfaces require an extra module from the vendor.

Do we have to replace our old ERP?

Usually not. If the ERP still works, adding the missing workflows, reports or integrations costs less and carries less risk than replacing it. A fully custom ERP is worth evaluating only when your processes are your edge and no package fits.

How should we choose an ERP vendor?

First decide whether you are buying a packaged ERP or extending and integrating the one you have. For a package, go to the vendor or a reseller. For extensions, integration or custom work, check whether the partner has done system integration, can write clear API specs and failure handling, and who maintains it after launch.

What should manufacturers watch for in ERP integration?

Common gaps are shop-floor workflows such as quotations, work orders, quality checks and equipment maintenance, plus data exchange with MES and warehouses. Decide which side is the master for each record (for example, part numbers and inventory follow the ERP), then set sync frequency and exception handling so figures match.

Should an SME choose a packaged ERP or a custom inventory system?

If your processes look like most companies' and the budget is tight, start with a packaged or cloud ERP. If they are unusual, need heavy customisation, or must connect deeply with e-commerce or POS, a custom inventory system that is just enough is often better value. We evaluate this together; not every step needs custom work.

How much does ERP integration cost?

For custom projects in Taiwan in 2026: each connected system is about NT$50k–200k, a single-workflow module about NT$500k–1M, a mid-size inventory or order system about NT$1M–2.5M, and a fully custom ERP usually starts at NT$2.5M. ERP licences and API modules from the vendor are extra.
