Gonexz Books

Features

Everything you need for everyday financial administration

Gonexz Books connects your sales, purchases and reports so each document builds on the last. Here's what that looks like in practice.

Invoicing

Invoices that look professional and keep track of themselves

The challenge

Invoices built in a word processor get misnumbered, go out without payment details, and are hard to follow up once they leave your outbox.

How Gonexz Books helps

Create numbered invoices with your logo, tax breakdown and payment details, then email the PDF or print it. Gonexz Books tracks each invoice from draft to paid and flags the ones that are overdue.

  • Automatic document numbering and PO references
  • Email PDF invoices and payment reminders
  • Record full or partial receipts against each invoice
  • Recurring invoices for retainers and regular work
  • Credit notes, debit notes, sales returns and delivery orders

Quotations

From quotation to invoice without retyping a line

The challenge

When quotations live in email threads, it's easy to lose track of what was sent, what was approved, and which version the customer actually agreed to.

How Gonexz Books helps

Prepare a quotation, send it, and record whether the customer approved or rejected it. Revise when terms change, and convert an approved quotation into an invoice in one step.

  • Sent, approved and rejected status for every quotation
  • Revisions keep the history of what changed
  • One-click conversion to an invoice
  • Attach your own terms and conditions pages

Purchases & expenses

Know what you owe, not just what you're owed

The challenge

Supplier bills and receipts pile up in drawers and inboxes, so payables and spending are only clear when someone sits down to reconcile them.

How Gonexz Books helps

Manage vendors, purchase quotations, purchase orders and vendor bills in the same workspace as your sales. Record payments, categorise expenses, and scan a receipt photo to pre-fill an expense for you to review.

  • Vendors, purchase orders and vendor bills
  • Expense categories and recurring expenses
  • Receipt scanning to pre-fill expense details
  • Mark expenses as billable and invoice them to a client

Reports

A clearer picture of how the business is doing

The challenge

Answering simple questions such as "who owes us money?" or "did we make a profit last quarter?" shouldn't require a weekend with spreadsheets.

How Gonexz Books helps

Profit and loss, sales and purchase reports, receivables and payables ageing, payment history, and client and vendor statements are built from the documents you already create.

  • Profit and loss, sales and purchase reports
  • Outstanding receivables and payables
  • Client and vendor statements you can email
  • Export to CSV, Excel or PDF, or schedule reports by email

GST & tax

Tax calculated on every line, summarised when you need it

The challenge

Getting tax right on each invoice and then adding it all up at filing time is where many small businesses lose hours.

How Gonexz Books helps

Define the tax rates your business uses, choose inclusive or exclusive pricing, and Gonexz Books calculates tax per line. Output and input tax reports summarise it by rate, and Singapore businesses get a report laid out like the GST F5 return.

GST calculated on each invoice line and summarised in an F5-style return INV-0141 9% 1,500.00 9% 300.00 Subtotal 1,800.00 GST 9% 162.00 Total 1,962.00 GST F5 Jul – Sep 2026 Output tax 4,212.00 Input tax 1,386.00 Net GST 2,826.00
  • Tax-inclusive or tax-exclusive pricing
  • Output tax and input tax reports by rate
  • GST F5-style report for Singapore
  • Tax registration numbers on your documents

Clients & inventory

Customer records and stock levels in one place

The challenge

Customer details, price agreements and stock counts often sit in different places, so quoting accurately takes longer than it should.

How Gonexz Books helps

Keep client and vendor records with addresses, contacts and tax numbers. Set client-specific price lists, track products across warehouses, and see stock on hand before you promise a delivery.

  • Client and vendor records
  • Client-specific price lists
  • Products, warehouses and stock movements
  • Stock on hand, stock card and low-stock reports

Sharing & assistance

Send documents where your customers already are

The challenge

Customers miss emails. Following up by phone or chat means attaching files by hand and keeping no record of what was sent.

How Gonexz Books helps

Send invoices and quotations by email, or by WhatsApp when it's enabled for your workspace. Signed-in users can ask the built-in assistant for help using the product, and it can hand the conversation to our team.

  • Email documents directly from Gonexz Books
  • WhatsApp sharing for invoices and quotations (when enabled)
  • In-app help assistant with escalation to our team

Team & controls

Give your team access to what they need, and nothing more

The challenge

Sharing one login across the office makes it impossible to know who changed what, or to keep sensitive figures private.

How Gonexz Books helps

Invite each person with their own account and a role — admin, accountant, sales person or viewer. Important actions are recorded in an audit log, and two-factor authentication protects every sign-in.

What each role can do: admins manage everything, accountants work with invoices and reports, sales people with invoices, and viewers can only look Invoices P&L Settings A Admin A Accountant S Sales V Viewer View View
  • Individual accounts with role-based permissions
  • Audit log of important changes
  • Two-factor authentication and trusted devices
  • Your branding on documents and emails
