Running a small business, especially one that serves other businesses like tradespeople, often means dealing with unique payment structures. Imagine operating a brick-and-mortar store where your customers, busy professionals, select their products but don't pay on the spot. Instead, they need all their purchases consolidated into a single invoice at the end of the month. This "invoice later" or "on account" payment method is common in B2B settings, but setting up your Point of Sale (POS) system to handle it efficiently can feel like a puzzle. This guide will walk you through how to configure your POS for 'invoice later' transactions, ensuring you can manage accounts, track unpaid orders, and streamline your billing process without a headache.

Setting Up Your POS System for "On Account" Payments

The core challenge when implementing an "invoice later" system is ensuring your POS can correctly classify transactions that aren't immediately paid. You need a way to mark sales as "on account" and track them as outstanding or unpaid, rather than processing them as completed cash or card transactions. Most modern POS systems offer features that can be adapted for this purpose.

Creating an "On Account" Payment Option

Your first step is to configure a specific payment type within your POS for "on account" sales. This isn't a traditional payment method like cash or credit card; instead, it acts as a placeholder signifying that payment will be collected later. Think of it as an internal flag.

Custom Payment Type: Look for options like "Custom Payment," "Other Payment," or "Store Credit" within your POS settings. You'll often be able to rename this. Opt for something clear like "On Account," "Invoice Later," or "Customer Account."
Link to Accounts Receivable: Ideally, this custom payment type should directly link to an "Accounts Receivable" module or report within your POS or integrated accounting software. This ensures these transactions are recorded as monies owed to your business.
Training Staff: Clearly train your staff on when and how to use this non-standard payment option. Emphasize that it's only for pre-approved customers with established credit terms.

Upon selecting "On Account" during checkout, the order should automatically be marked as unpaid in your system's administration portal. This crucial step prevents misclassification and keeps your books accurate for pending payments.

Tracking Unpaid Orders and Customer Accounts

Once an order is marked as "on account," effective tracking becomes paramount. You need to know exactly who owes what, and when. Your POS system, or an integrated accounting solution, should provide a clear overview of all outstanding invoices.

Customer Profiles: Ensure every customer using the "invoice later" option has a detailed profile in your POS. This profile should include their business name, contact information, preferred billing address, and any specific credit terms agreed upon.
Transaction History: Each "on account" sale should be logged against the customer's profile, creating a running history of their purchases. This is vital for later consolidation.
Accounts Receivable Reports: Regularly review your Accounts Receivable (A/R) reports. These reports will show you all outstanding balances, their age (how long they've been unpaid), and who owes them. This proactive monitoring helps prevent overdue payments.

A robust POS system will provide a dashboard or reporting feature where you can see all open invoices at a glance, allowing you to easily identify which customers need to be billed.

Consolidating Multiple Orders into One Invoice

The real time-saver for both you and your tradespeople customers is the ability to send a single, comprehensive invoice covering all their purchases over a specific period, typically a month. This requires your POS or accounting software to aggregate individual transactions.

Leveraging Your POS for Batch Invoicing

Many POS systems designed for B2B operations or those with strong accounting integrations offer a batch invoicing feature. If yours doesn't, you'll likely need to export data and use accounting software.

Identify Consolidated Billing Feature: Look for options like "Batch Invoicing," "Consolidate Customer Orders," or "Statement Generation" within your POS or linked accounting platform.
Select Customer & Date Range: You should be able to select a specific customer (or group of customers) and a date range (e.g., the last month). The system should then pull all "on account" transactions for that customer within that period.
Generate and Send Invoice: The system should then generate a single, detailed invoice itemizing each purchase, its date, and cost, along with the total amount due. Most systems will allow you to generate a PDF and email it directly to the customer.

If your POS doesn't offer this directly, you'll need a workflow that involves exporting the customer's transaction data (often to a CSV file) and then importing it into a dedicated accounting software (like Xero, QuickBooks, or similar) to generate the consolidated invoice. While an extra step, it's still more efficient than individual invoicing.

Choosing the Right POS System for "Invoice Later" Needs

Not all POS systems are created equal, especially when it comes to sophisticated features like "invoice later" and batch invoicing. When making your choice, consider these key functionalities:

Strong Accounts Receivable Features: Can it track who owes you money and for how long? Does it generate aging reports?
Flexible Payment Options: Does it allow for custom payment types that don't immediately process funds?
Customer Relationship Management (CRM) Integration: Can you maintain detailed customer profiles, including credit terms and billing preferences?
Integrated Accounting: Does it integrate seamlessly with popular accounting software, or does it have robust built-in accounting modules?
Reporting Capabilities: Can it generate reports not just on sales, but on outstanding balances and customer statements?

For a small business to successfully implement an invoice later system, the right POS is critical. It should simplify, not complicate, your operations. Some systems offer more advanced features suitable for this model straight out of the box, while others might rely on integrations.

Streamlining Your Billing Workflow: Actionable Steps

Beyond just the technology, setting up a smooth "invoice later" system involves clear processes and communication. Here's a checklist to ensure success:

Establish Credit Terms: Before offering "invoice later," define clear credit terms for your business customers. This includes payment due dates, late payment policies, and any eligibility criteria.
Customer Onboarding: Create a simple application process for customers who wish to pay "on account." Get their business details, preferred billing contact, and agreement to your terms.
Regular Reconciliation: Periodically reconcile your "on account" sales with your accounting records. This ensures accuracy and helps catch discrepancies early.
Automate Reminders: If your POS or accounting software allows, set up automated email reminders for upcoming or overdue invoices. This saves time and gently prompts customers.
Dedicated Billing Cycle: Stick to a consistent billing cycle (e.g., invoices sent on the 1st of every month, due on the 15th or 30th). Predictability benefits both you and your customers.

Implementing these steps will not only simplify your POS invoice later system but also enhance your professional relationship with your business clients, providing them with convenience while maintaining your cash flow.
