Leads

Record the enquiry before it becomes a quote

Most small businesses lose work in the gap between the phone call and the follow-up. The lead module is a deliberately simple CRM: name, contact details, what they asked for, and where the conversation is up to.

When the enquiry turns into real work, the lead becomes a quote with the customer details already filled in. When it doesn't, you still have a record of who asked and what for — which is what makes the next quiet month easier to work through.

  • Capture the enquiry Contact details, the job, the source and a note on what was discussed.
  • Track the stage See at a glance which enquiries are live and which have gone cold.
  • Convert in one click The lead becomes a quote, order or invoice without re-entering anything.

Quotes

Quote the job, then convert the yes

Build an itemised quote from your saved products and services, set an expiry date, and email it as a PDF. The quote is stored against the customer, so months later you can still see exactly what you offered and at what price.

When the customer accepts, the quote becomes an order or an invoice with a single click. The line items carry through untouched, which closes the most common source of billing disputes: the difference between what was quoted and what was eventually invoiced.

  • Itemised, not lump sum Line items let the customer see what they'd be removing, not just the total.
  • GST stated up front Show GST as its own amount so the invoice contains no surprises.
  • Expiry dates Hold the price for 30 days rather than indefinitely.

Orders

Know what has been delivered before you bill for it

Between an accepted quote and a sent invoice there is usually work: a job to schedule, materials to order, a delivery to make. The order module holds that middle stage so the invoice goes out when the work is genuinely done rather than whenever someone remembers.

Orders carry the quoted lines forward, and mark what has been fulfilled. Invoice the completed order and the document is already correct.

  • The quote becomes the order Approved lines carry forward with quantities and prices intact.
  • Track fulfilment See what has been delivered and what is still outstanding.
  • Invoice when it's done One click turns the completed order into a tax invoice.

Invoices

An invoice the ATO will accept, in under a minute

The invoice generator produces documents that carry every field the ATO requires on a valid tax invoice. Switch GST off and the document becomes a plain invoice instead — the GST column disappears and the words 'Tax invoice' come off the header, which is exactly what is expected of a business that is not registered.

Download the finished invoice as a PDF, print it, or send it straight to the customer's inbox from InvoiceGen.

  • Every required field Identity, ABN, date, description, GST amount and taxable extent.
  • The $1,000 rule handled Above $1,000 the buyer's identity or ABN is included automatically.
  • PDF or email Send it from InvoiceGen or download it and attach it yourself.

FAQ

Frequently asked questions

Which features cost money?

None of them. Lead management, quoting, order management and invoicing are all included at no cost, with no limit on how many records you create. There is no premium tier that unlocks the useful parts.

Do I have to use all four modules?

No. Most people start with invoicing alone and never touch the rest, which is fine — the invoice generator works on its own. The modules are there for the businesses that quote before they invoice, or that want the enquiry recorded before the quote goes out.

Can more than one person use the same account?

Yes. You can create a team and invite the people who need access, so quotes raised by one person and invoices raised by another sit against the same customer record.

Can I customise the look of my invoices?

You can add your business logo and your details, and the document carries them through to the PDF. The underlying layout is deliberately conventional, because an invoice that looks like an invoice gets paid faster than one that looks like a design exercise.

Where is my data stored?

In your InvoiceGen account, reachable from any browser you sign in to. Nothing is held only on the device you created it on, so an invoice started on a phone on site can be finished on a laptop later.
