Everything your team needs. Nothing they don't.
Most SMEs run four or five separate tools to handle what HisaBooks does in one place. From the first customer quote to the payslip at the end of the month.
- Country-based packages Singapore pricing is shown in SGD, with GST billing and CPF-aware payroll support for local companies.
- Billing to close Quotes, invoices, credit notes, payments, and AR/AP, all connected.
- Field to billing Service reports and delivery orders link directly to invoice creation and purchase orders.
- Catalog to inventory Define goods and services once in the item catalog. Lines auto-fill into quotes and invoices, and the inventory module tracks stock movements as goods come in and go out.
- Self-service upgrades Companies can upgrade their plan, add workspaces, and adjust user or employee counts directly from settings without contacting support.
- Free to paid without migration Start on a branded free workspace, then remove branding and raise limits later from subscription settings on the same company code.
From quote to payment, fully tracked
Create quotations, convert them to invoices, issue credit notes, log customer payments, and track your AR/AP. An item catalog auto-fills billing lines with pricing and GST treatment, and the inventory module keeps goods stock levels current alongside the billing workflow — no separate system needed.
- Quotations, invoices, and credit notes with custom PDF themes
- Singapore GST billing with standard-rated, zero-rated, exempt, and out-of-scope treatment options per document
- GST registration setup with TAX INVOICE label and GST registration number printed on documents as required by IRAS
- Item catalog for goods and services with item codes, default selling price, cost price, GST treatment, and preferred supplier — auto-fills billing document lines
- Inventory module with stock-in, stock-out, adjust-up, adjust-down, and opening-balance entries, reorder level alerts, and per-item movement history
- Customer payment logging with running balance per customer
- AR / AP overview with aging buckets and collection context
- Finance ledger linking transactions to customers, suppliers, and tasks
- Customer statements available as branded PDFs

- Employee records with contract, banking, and emergency details
- Payslips with Singapore CPF support (Citizen/PR tiers, SDL, SHG), AIS/IR8A preparation, and CPF rate engine with 2026 tables built in

Take the same workspace out to the field
A dedicated mobile app for iOS and Android puts the day-to-day of HisaBooks in your pocket, so engineers, sales staff, and managers can keep moving without waiting to get back to a desk.
- View the dashboard, tasks, and service reports, and create or update them on site
- Create and review quotations, invoices, delivery orders, and credit notes
- Check payslips, attendance, leave, and HR records from a phone
- Same company login and the same role-based permissions as the web portal
- Push notifications for approvals, reminders, and status updates
- Open any document as a PDF and share it directly from the app
Built to be trusted with your company's data
Payroll, banking details, and customer records deserve more than a login screen. HisaBooks is built with the access control and audit visibility a growing company needs to hand out logins with confidence, not worry about them.
- Two-factor authentication any user can turn on, with recovery codes if a device is lost
- Role-based permissions down to individual actions, so a growing team only sees what its role requires
- Per-user permission overrides for exceptions, without changing someone's entire role
- A full audit trail of key actions, changes, and access decisions, reviewable from the company dashboard
- Encrypted sessions, tenant-isolated data, and hashed passwords that are never stored or shown in plain text
- Repeated failed sign-ins are automatically slowed and locked out
Every document looks like it came from you
Choose from a catalog of professionally designed PDF themes, then fine-tune the details, fonts, colors, logo, layout, and footer, so invoices, quotations, service reports, and payslips all carry your company's identity consistently, not a generic template.
- A catalog of ready-made PDF themes to start from
- Custom accent color, text color, table styling, and border color per company
- Font family and heading, body, and label text sizes tuned to your preference
- Logo size and placement, plus header layout, side-by-side or stacked
- Custom footer notes and an optional watermark for drafts or confidential documents
- One setting applies everywhere: invoices, quotations, purchase orders, delivery orders, credit notes, service reports, and payslips
Start free and upgrade when the team is ready
Free Starter gives a real company workspace, not a demo. Teams can manage customers, items, quotations, invoices, service reports, and finance basics straight away, then move to a paid plan later without rebuilding the tenant.
