Quote, order, delivery note, invoice, payment: the chain your business software must hold together

01

Why the document chain matters more than it seems

An order lost among emails, a delivery note that cannot find its matching invoice, a payment nobody links to the right document: these are the frictions that make a business slower than it should be. Nebulas ERP connects customers, suppliers, quotes, orders, delivery notes, invoices, payments, inventory, analysis and projects in the same operational flow. Data, lines, prices, terms and relationships between documents follow the work from the first quote to the closing of payment. Modules, permissions, printouts, rules and integrations are configured around the company's processes, so the sales chain stays readable for whoever follows it every day, from sales to administration.

02

The five steps of the sales cycle

Steps

1. The quote opens the cycle: lines, prices and terms are recorded and stay linked to all the customer's subsequent documents.
2. The order inherits data from the confirmed quote, keeping prices and terms consistent along the whole document chain.
3. The delivery note records the delivery and automatically updates the inventory movement linked to the original order.
4. The electronic invoice is generated from the previous documents, keeping lines and relationships traceable up to the final payment.
5. The payment closes the cycle and updates the due-date schedule, ledger and customer history.

03

What is needed before connecting the documents

Prerequisites

• Modules activated for quotes, orders, delivery notes, invoices, inventory and analysis linked to the same flow.
• Roles and permissions defined for who creates, approves, edits and closes each document.
• Price lists, templates and rules configured to keep prices and terms consistent across the cycle.
• Custom fields set up for the specific information required by the company's processes.
• Integrations and APIs connected to external services useful for the document flow, if needed.

04

A hypothetical case: from a recurring order to payment

Hypothetical example: a distribution company receives a recurring order from a regular customer. The already approved quote generates the order with the same agreed terms. The delivery note accompanies the delivery and automatically updates inventory in and out. The electronic invoice is created, sent and monitored through the exchange system, with statuses and notifications close to the document cycle. The payment is recorded and the due-date schedule updates together with the ledger. Each step stays linked to the previous one, so whoever follows the customer can retrace the entire chain, from the first quote to the closing of payment, without searching for information in separate tools.

05

What to check to keep the chain solid

• Verify that the due-date schedule reflects the actual payment and collection deadlines recorded in the documents.
• Check the statuses and notifications of electronic invoices sent and received through the exchange system for each case.
• Compare inventory availability with orders to be fulfilled and updated committed quantities.
• Periodically review cost centers, revenue centers and VAT summaries for data consistency.
• Verify that automatic inventory movements match the delivery notes issued and received in the cycle.

06

How Nebulas ERP concretely supports the flow

Nebulas ERP creates, sends, receives and monitors XML electronic invoices through the exchange system for supported public administration, business-to-business and business-to-consumer cases, keeping statuses, notifications, search and history close to the document cycle. Inbound and outbound movements, adjustments and automatic updates refresh availability, committed quantities, orders to fulfill and history, while reorder and goods-arrival proposals link demand to the supplier cycle. Due-date schedules, collections, payments, reminders, ledger entries, cost and revenue centers, VAT summaries, widgets and analysis make administrative activity and operational results readable across the whole sales cycle.

07

How to set up the flow step by step

Steps

1. Activate the modules useful for the sales cycle: quotes, orders, delivery notes, invoices, inventory and analysis.
2. Configure roles and permissions for every phase of the document process, from quote to payment.
3. Set up price lists, templates and rules to keep prices and terms consistent across documents.
4. Connect external services through available integrations and APIs, if useful for the operational flow.
5. Import or export data to keep records, price lists and documents consistent over time.

The next step

Anyone who wants to see how quote, order, delivery note, invoice and payment stay linked in a single operational flow can request an overview of Nebulas ERP and assess which modules to activate for their own sales cycle. Configuring roles, permissions, price lists and rules around existing processes is the first step toward making the document chain readable for the whole company, from sales to administration, without searching for scattered information across different tools.
