Episcript builds custom Invoicing Software around the way your business quotes, bills and collects. Your numbering, credit terms, approvals and layouts stay as they are, and AI features can take on selected billing work.
Built in Singapore for distributors, consultancies and service businesses that bill on their own terms.
Invoicing and Billing Software runs quotations, invoices, payments and statements from one record, and you can start at any step.
Issue quotations from the customer record and convert them into orders.
Confirm the items, prices, delivery schedule and any deposit.
Print the delivery order and update stock in one step.
Raise a GST tax invoice under your own numbering and layout.
Record PayNow, GIRO, card or bank payments against each invoice.
Issue statements, apply credit notes and reconcile with your accounts.
Each capability is configured to your billing rules during the build, not switched on from a template.
Tax invoices carry your GST registration number, the tax amount and the required particulars. Standard rated, zero rated and exempt supplies follow their own treatment, and credit notes reverse them.
Bill overseas customers in their own currency while reporting stays in Singapore dollars, showing GST amounts in Singapore dollars where required. Contract rates can be kept per customer.
Accept PayNow, PayNow Corporate, cards, GIRO and bank transfer. Integrated payments update the invoice and generate the receipt, and a part payment leaves the balance for the next reminder.
Bill from the stock records your warehouse works from. Invoicing a delivered order writes the stock movement, and a quotation can check availability before a delivery date is promised.
Track customer receivables and supplier payables within the same system. Supplier invoices can be matched against purchase orders raised in a Procurement System before payment is approved.
Report sales by customer, product or salesperson, collections by period, and outstanding balances by age, all from live billing data rather than an exported spreadsheet.
The system raises recurring invoices for retainers, subscriptions and monthly fees, sends each one and follows it up on time. Property managers bill monthly rent the same way in our Property Management Software.
Sent under your own template and reply address
Before and after the due date, per customer
Any customer, any period, with the closing balance
Part payments logged with the user and date
Local billing practice is built into the system rather than adapted from a product designed for another market.
Templates carry the particulars IRAS expects on a tax invoice, from your GST registration number to amounts before and after GST. Credit notes reference the original invoice.
Each PayNow, PayNow Corporate or GIRO payment is recorded with its bank reference against the invoices it settles. A queried receipt traces straight to its transfer.
Invoices, credit notes, receipts and statements stay retrievable for your retention period, ready for GST filing, and your accountant works from the same figures.
Where IRAS requires invoice data to go through InvoiceNow, Singapore's Peppol e-invoicing network, we scope the connection to an accredited Access Point Provider, timed to your IRAS implementation date.
User permissions, role based access to customer and payment records, and activity logs support your PDPA obligations. Your own policies and staff practices carry the rest.
Each feature is built in its own phase, and your staff review its output before a customer sees it.
AI reads a supplier invoice or delivery order, lifts out the line items and matches them against the purchase order before an approver signs.
AI matches incoming payments and bank references to open invoices, including part payments and combined settlements, then flags the ones a person should check.
AI drafts the reminder or the reply to a billing query from that customer's history. Your team edits the wording and sends it.
AI scores open invoices against how each customer has paid before and names the accounts likely to run past due this month.
AI projects what should reach the bank over the coming weeks, working from your open invoice book and the payment patterns behind each account.
AI reviews a draft invoice for duplicated lines, a missing GST treatment or a price that differs from the quotation, and raises anything unusual.
Your billing runs in the new system, and your accounts stay in Xero, QuickBooks or whichever product you use.

ZapierRunning something not listed? Name it during scoping and we will price the connection with the build.
A custom build follows your own billing process: invoice types, approval steps, numbering, discount rules and layouts match how you already bill, and it connects to your stock, CRM or website. A packaged product suits straightforward billing.
E-invoicing is becoming mandatory in stages for GST-registered businesses in Singapore: IRAS is progressively requiring their invoice data to go through InvoiceNow, from an implementation date it sets. We time your InvoiceNow connection to that date.
Customers can pay by PayNow, PayNow Corporate, credit or debit card, GIRO or bank transfer. Integrated payments update the invoices they settle, and a part payment leaves the remaining balance on the account.
Invoices, credit notes and payments can sync with Xero or QuickBooks, and your accountant works from the figures your finance team issues. We agree what moves, and in which direction, during scoping.
AI we build into the system checks invoices rather than issuing them alone. It flags duplicated lines, a missing GST treatment or a price that differs from the quotation, reads supplier invoices and matches payments, with staff reviewing every output.
Implementation runs in stages: scoping, build, migration, testing with your finance team, then go live, with the timeline set by the document types and integrations in scope. We migrate customer records, outstanding invoices, opening balances and your catalogue.
Custom Invoicing Software is priced on scope: the number of invoice and document types, how much of the quotation to payment sequence you need, the integrations and the data to migrate. An AI phase is costed separately.
The Invoicing Software can send each invoice as e-invoice data through an accredited Access Point Provider onto InvoiceNow, Singapore's Peppol e-invoicing network, which delivers it to your customer's system. Invoice data reaches IRAS the same way where required.
Invoices can be raised in the customer's currency while management reporting stays in Singapore dollars, with GST amounts also shown in Singapore dollars where they apply. You set where rates come from and can keep a contract rate per customer.
A Singapore GST tax invoice generally shows the supplier and customer, the GST registration number, the invoice date and number, what was supplied, and the GST rate with amounts before and after GST. We build templates and validation around them.
The system supports your PDPA obligations through user permissions, role based access to customer and payment records, and activity logs showing who viewed or changed what. Hosting, backup and security are agreed before the build starts.
Billing often forms the finance layer of a custom ERP System, or draws quotations from a custom CRM.
Track project costs, milestones and billable time, then raise the invoice from the same project record.
