OctoberCMS - How to call a function inside a component - php

Question

I am building an order form and I warn you in advance I am a noob with backend dev :)
So my first component takes all data from the order form and saves it to the database, then I use this same data to generate a quote. After this I have a thrird part which generates the invoice if the quote is accepted, so far my code looks like this:
// this runs when order is submitted on front end (runs from same component)
public function onAddOrder() {
$this->submitOrder();
$this->submitQuote();
Flash::success('Order successfully submitted!');
return Redirect::to('/home');
}
public function submitOrder() {
// Add it to the database
$order = new Order();
$order ->quote_no = $this->generateQuoteNo();
$order ->company_name = Input::get('company_name');
$order ->client_name = Input::get('client_name');
$order ->client_email = Input::get('client_email');
$order ->emergency_contact = Input::get('emergency_contact');
$order ->due_date = Input::get('due_date');
$order ->project_name = Input::get('project_name');
$order ->quote_query = Input::get('quote_query');
$order ->order_no = Input::get('order_no');
$order ->order_type = Input::get('order_type');
$order ->save();
}
}
public function submitQuote() {
$quote = new Quote();
$quote->quote_no = $this->generateQuoteNo();
$quote->customer = Input::get('company_name');
$quote->job_name = Input::get('project_name');
$quote->order_no = Input::get('order_no');
$quote->proof_price = $this->calculateProofPrice();
$quote->sub_total = $this->calculateSubTotal();
$quote->vat = $this->calculateVat();
$quote->total = $this->calculateTotal();
$quote->save();
}
This works fine but then I would like to run another function if a selection is made but this component is under a different class and I am not sure how to reference it.
if (Input::get('quote_query') === 'Order') {
$this->AcmeInvoice->onSubmitInvoice();
}
If someone could help me to fire the public function onSubmitInvoice() I will really appreciate it.

You can instantiate the object in the class & fire it off? eg: $invoice = new AcmeInvoice(); //add namespace if not in the name space; $invoice->onSubmitInvoice();
if (Input::get('query') === 'Invoice') {
$invoice = new AcmeInvoice();
$invoice->onSubmitInvoice('quote_no');
}
