Custom ERP software, built around your own process

A custom ERP turns the processes you already run into one connected system, rather than forcing your team to adapt to the fixed workflow of a packaged product.

Most packaged ERP products come with a predefined way of moving from quotation to invoice. A custom build does not have to. We map your steps, use the terminology your staff already know, and build the modules your business actually needs. When the process changes, the system can change with it.

That approach runs through every module, from a custom CRM system at the front to payroll at the back. One database sits underneath it all, so customer details, stock codes and invoice lines do not have to be re-entered into separate systems.

What changes

Once the ERP is running

  • One record carries the customer, the order, the delivery and the invoice
  • Stock counts match the shelf, across every warehouse and outlet
  • Purchase requests reach the right approver the day they are raised
  • GST invoices and payment reminders issue on a schedule you set
  • Management reads live figures instead of last month's spreadsheet
Order to cash

How an order moves through the ERP

Six stages, one database. Each stage uses the information captured earlier, so the same order details do not need to be keyed in again.

  1. 1

    Quotation

    The CRM issues the quotation straight from the customer record.

  2. 2

    Sales order

    An accepted quotation converts to a sales order and reserves the stock.

  3. 3

    Purchasing

    Procurement raises purchase orders for any items that need to be replenished.

  4. 4

    Stock and delivery

    Received goods update stock, the picking list is generated, and the delivery order follows.

  5. 5

    Invoice

    A GST invoice is issued against the delivery, using your own layout and numbering.

  6. 6

    Payment and ledger

    PayNow, card or bank transfer clears the invoice and posts to the accounts.

Core modules

ERP software modules for Singapore businesses

Start with the ERP modules your business needs now, then add more later without creating another data silo.

Customer relationship management

The CRM tracks every enquiry from first contact to signed order. Leads route to a named salesperson, and quotations, calls and appointments sit on the contact record.

Inventory management

Stock counts update as goods move in, out and between warehouses. Serial numbers, stock codes and reorder alerts keep the shelf and the screen in agreement.

Invoicing and payment management

Issue GST invoices, credit notes and statements from the order they belong to. Reminders chase late payers, and payments post against the invoice as they clear.

Procurement management

Purchase requests travel through the approvers you name, then convert to purchase orders. Supplier records, budgets and three way matching sit in the same module.

Document management

Every contract, delivery order and certificate files against the record it belongs to. Indexed search finds a document by name, category or the words inside it.

Project management

Plan projects on a Gantt chart with dependencies, milestones and named staff. Time logged against a task feeds project costing and the client invoice.

HR and payroll

Payroll runs from the same employee record that holds leave, claims and attendance. Payslips, CPF submissions and statutory reports issue on your own schedule.

Point of sale

Take payment at the counter, on a tablet or on the road. Sales write straight to stock, and staff commission calculates as the receipt prints.

Stock and money

Stock, invoicing and payments in one ledger

Goods received, goods sold and money collected run through the same records. A sales order reserves the stock, the delivery order prints from that same line, the invoice follows the delivery, and the payment closes the loop.

  • Live stock counts across multiple warehouses, with full movement history
  • Low stock alerts and reorder points set product by product
  • Barcode scanners and stock take devices reading the same tables
  • GST invoices, credit notes and account statements issued from the order
  • Accounts payable and accounts receivable reported side by side

Where stock control is the whole job on its own, our inventory management system runs as a standalone build and connects to the rest later.

Selling

Point of sale and ecommerce on one product catalogue

Point of sale

The counter reads the same product list as the warehouse. A sale drops the stock count immediately, applies the loyalty points, and prints a receipt in your own layout. Split payments, refunds and credit notes all post back to the customer record. Where the shop floor is the priority, our POS system covers it as a build in its own right.

Ecommerce

The online store draws products, prices and stock from the ERP rather than a second catalogue. Orders placed at midnight appear in the same order queue as the ones your sales team keys in. Customers pay by card, bank transfer or PayNow, and the invoice issues from the same module that bills your trade accounts.

Capability

AI features that can be built into your ERP software

AI features are scoped with you and can be introduced in their own phase. They work with information already held in your ERP, with each workflow tested before it goes live.

Enquiry scoring and routing

AI reads each new enquiry, scores it against the deals you closed before, and routes it to the salesperson most likely to win it.

Illustration of AI drafting a reply to a customer inside the ERP

Drafted replies and follow ups

AI drafts the reply, the quotation cover note or the chase message from the customer history in your ERP. Your staff edit the wording and send it.

Illustration of AI forecasting stock demand from sales history

Stock and demand forecasting

AI reads sales history and supplier lead times, suggests reorder points, and names the products likely to run short next month.

Illustration of AI reading a supplier invoice and matching it to a purchase order

Supplier invoice reading

AI reads a supplier invoice or delivery order, pulls out the line items, and matches them against the purchase order before an approver signs.

Evaluating

Custom ERP software vs off-the-shelf ERP systems

Both approaches can work well. The better fit depends on how standard your processes are, how much control you need, and how quickly you want to go live.

Implementation

How we implement a custom ERP system

We normally release the ERP in phases, starting with the module that costs your team the most time. Each phase is tested with real workflows and data before the next one begins.

Your team can keep working throughout the implementation. Existing systems can remain in place during transition, while staff learn and test the new ERP one phase at a time.

  1. 1

    Scoping workshop

    We sit with the people who run the process and map it, step by step, including the exceptions nobody writes down.

  2. 2

    Written scope and quotation

    You receive the module list, the integration list and a price against it. The scope decides the price, not the other way round.

  3. 3

    Build in phases

    The first phase focuses on the processes creating the most manual work or operational friction. You test each screen and tell us what to adjust before we move on.

  4. 4

    Data migration

    Customers, stock, open orders and outstanding balances move across. Your team checks a test import before we run the real one.

  5. 5

    Launch, training and support

    We train each role separately, then hand over. Support after launch follows the arrangement written into your agreement.

Built for Singapore

ERP software for Singapore business requirements

A Singapore ERP has to do more than manage generic workflows. We can scope local invoicing, payment, payroll and data-control requirements into the same system.

GST and InvoiceNow

GST invoicing is built into the invoicing module. Where InvoiceNow connectivity is required, it can be scoped as an integration based on the applicable IRAS requirements and the InvoiceNow-ready provider used for the project.

PayNow and local payments

Invoices and customer payments can support PayNow alongside cards and bank transfers, with payment records linked back to the customer and invoice.

Payroll and CPF workflows

HR and payroll can cover employee records, leave, claims, attendance, payslips, CPF submissions and statutory reporting for Singapore operations.

PDPA supporting controls

Role-based permissions, access controls and activity logs can support your organisation's PDPA processes by controlling who can view or change business and customer records.

Connected

Integrations with the software you already run

The ERP talks to the tools your team opens every day. Invoices post across to your accounting platform, calendar entries sync both ways, and messages go out over WhatsApp from inside the customer record.

  • Xero
  • QuickBooks
  • Microsoft 365
  • Google Workspace
  • WhatsApp
  • Mailchimp
  • Facebook
  • PayNow
  • Telephony

We can also wire in a telephony service, which lets your team make calls and send text messages without leaving the customer record. Tell us what you already run, and we will confirm exactly what each integration covers before you commit to anything.

Questions

ERP software FAQs for Singapore businesses

ERP software brings core business processes into one connected system and database. Instead of running sales, inventory, purchasing, invoicing, projects and payroll in separate applications, an ERP lets those functions share the same records, workflows and reporting.

The price follows the modules you need, the number of people using them, and what the ERP has to connect to. A build covering sales, stock and invoicing costs far less than one adding payroll, projects and a customer portal. We scope the work with you first, then quote a fixed price against that written scope.

Government support may be available for qualifying ERP, automation and digital transformation projects in Singapore. The available schemes, support levels and eligibility rules can change, and approval rests with the relevant agency. If funding is important to the project, tell us during scoping so the quotation and supporting documents can be prepared around the current requirements.

The timeline follows the number of modules in the first phase. A single module reaches your team quickly. A full ERP covering sales, stock, purchasing, invoicing and payroll takes considerably longer, and we split it into phases rather than one launch. You receive a written schedule with the quotation, and every phase carries its own dates.

Yes. The ERP connects to Xero, QuickBooks, Microsoft 365, Google Workspace, Mailchimp, Facebook and WhatsApp. Invoices post across to your accounting platform, calendar entries sync both ways, and staff send WhatsApp messages from inside the customer record. A telephony service can be added as well, for calls and text messages.

Yes. Most clients begin with the modules that hurt most, often stock and invoicing, then add procurement, projects or payroll later. Every module writes to the same database, which means a later addition reads the history already there. We agree the order at scoping and price each phase separately.

Yes. The invoicing module issues GST compliant invoices, credit notes and account statements, and records payments made by PayNow, card or bank transfer. Reminders chase overdue invoices on a schedule you set. Multi currency invoicing is available where you sell overseas, and every document carries your own layout and numbering.

InvoiceNow connectivity can be scoped into the invoicing workflow where it is required. The exact implementation depends on the applicable IRAS requirements and the InvoiceNow-ready solution or access-point provider used for the project, so we confirm the integration approach during scoping.

We migrate it. Customer records, stock lists, open orders and outstanding invoices move across from spreadsheets, accounting software or an older system. We clean and map the data with your team, run a test import, and ask you to check the result before launch. Records that no longer earn their place stay in an archive.

Through permissions, activity logs, consent records and access controls. Each role sees only the records it needs, and the system logs who opened or changed a record. Software alone does not make an organisation compliant. Your own policies, retention rules and staff training carry the rest, and the ERP records the evidence behind them.

Enquiry scoring, drafted replies, stock forecasting, supplier invoice reading and anomaly alerts are the common requests. Each one works with information already held in your ERP rather than a model trained on your files. We scope the features you want, price them as their own phase, and demonstrate them before they go live.

When your process is the reason customers stay, or when no product on the market fits it without heavy configuration. Packaged ERP platforms carry a great deal of ready made functionality and reach your team quickly. A custom build costs more at the start and fits exactly, which matters most where the workflow is unusual.

Ownership, hosting and support are set out in the agreement signed before the build starts, which removes any ambiguity later. We put the arrangement in writing at quotation stage. Ask us about source code, hosting location and response times during scoping, and the answers go into the contract rather than onto a sales page.
