Overview

Odoo, adapted to how Singapore businesses run

Standard Odoo gets you most of the way. The last part is local.

Odiware adapts Odoo for Singapore companies whose workflows, compliance obligations and growth plans go beyond the standard setup — including GST-compliant invoicing, InvoiceNow/Peppol integration, and CPF-aware payroll configuration.

Whether you need to adjust one module or build a set of custom ones, the work follows the same upgrade-safe approach as our main Odoo customization services, with the Singapore-specific rules built in.

Adapting Odoo ERP to your workflows, Singapore compliance requirements and growth goals.

Singapore requirements

Singapore rules we build into Odoo

Odoo's Singapore localization covers the base chart of accounts and GST taxes. These are the local requirements that most often need customization on top of it.

Requirement What it asks of your business What we customize in Odoo
GST at 9% and the GST F5 return GST-registered businesses charge GST at the current 9% rate, issue tax invoices and file the F5 return with IRAS. Tax mappings, tax invoice layouts carrying your UEN and GST registration number, and an F5 box-mapping report built from posted entries.
InvoiceNow (Peppol e-invoicing) IRAS is phasing in invoice data transmission through InvoiceNow: newly incorporated voluntary registrants from 1 November 2025, all new voluntary registrants from 1 April 2026, and all GST-registered businesses by April 2031. E-invoice output in the Singapore Peppol format, the connection to your IMDA-accredited Access Point provider, and a sent/failed status on every invoice.
CPF contributions Employers pay CPF on wages at rates that vary by employee age band and wage level, and the rates are revised over time. Payroll rules or payroll exports structured for CPF, with the age-band rates held in configuration so they can be updated without code changes.
PayNow and local banking Customers pay by PayNow, card and bank transfer, and finance teams reconcile against Singapore bank statements. Payment-provider integrations, bank statement import and reconciliation rules matched to how your bank reports transactions.
Regional, multi-currency trade Singapore hubs often book in SGD while buying and selling in USD, MYR or IDR across several warehouses or 3PLs. Multi-currency pricelists and revaluation reports, multi-warehouse routes and 3PL handovers, and landed-cost tracking.
Personal Data Protection Act (PDPA) Organisations must control who can see personal data and how long it is kept. Record rules and access rights by role, consent fields in CRM and retention rules for contact data.

Dates and rates change: check the current position on the IRAS GST InvoiceNow requirement page before you plan. The general approach to custom modules, Studio and upgrades is covered on our main Odoo customization services page.

Customization FAQ

Odoo customization in Singapore: FAQs

Yes. Odoo's Singapore localization provides the base chart of accounts and GST taxes at the current 9% rate. We customize tax mappings, tax invoice layouts with your UEN and GST registration number, and an F5 box-mapping report, so your accountant can file with IRAS from Odoo data.

Yes. InvoiceNow runs on the Peppol network, so Odoo produces the e-invoice in the Singapore Peppol format and sends it through an IMDA-accredited Access Point provider. We set up that connection and show the delivery status on each invoice. IRAS is phasing the requirement in, starting with new voluntary GST registrants from November 2025 and April 2026.

Yes. We structure payroll rules or payroll exports so CPF contributions follow the age and wage bands published by the CPF Board, and keep the rates in configuration rather than code so they can be updated when CPF revises them.

Yes. Common requests are PayNow and card payments through a payment provider, bank statement import for reconciliation, and Xero or Shopify syncs during a phased move to Odoo. Each integration is scoped around the data that moves, how often, and what happens when a sync fails.

No. Odiware is headquartered in Bengaluru, India, and delivers Singapore projects remotely, with requirement calls, reviews and support scheduled in Singapore business hours (SGT).

It depends on scope: a report layout or approval rule is much smaller than a custom module with integrations. For reference, one of our full rollouts with custom labour, attendance and payroll modules took 3 months. You get a timeline after the fit-gap review.

Cost follows scope: the number of modules, business rules, integrations, reports, data work and testing. We do not quote a figure without a defined requirement; the free customization review gives you a scoped estimate, and the cost factors are explained on our main Odoo customization services page.

Not automatically. Each custom module must be updated for the target Odoo version and tested on an upgraded copy of your database. We build with inheritance and separate modules to keep that effort small, and handle upgrades through our Odoo migration services.
