How Credit Card Processing Works
The process typically begins when a customer pays an invoice or places an order using a credit card. The payment solution securely sends the transaction for authorization through the payment gateway and merchant processor. The issuing bank approves or declines the transaction, and the result is returned to the payment application.
When a transaction is approved and recorded, the accounting workflow should connect the payment to the correct customer and invoice. The exact steps depend on the Sage 100 version, the payment integration, and whether the business processes payments from sales orders, invoices, or a separate payment interface.
Authorization and settlement are different stages. Authorization confirms that the transaction has been approved under the processor's rules; settlement is the later process through which approved transactions are submitted and funds are transferred to the merchant, usually after processing fees and other adjustments. Finance teams should distinguish an approved card payment from the actual deposit received in the bank account.
Core Components and Accounting Records
A typical implementation combines the accounting application, payment gateway, merchant account, and bank settlement process. Each component has a separate role: Sage 100 maintains customer and transaction records, the gateway transmits payment information, the processor handles card transaction routing, and the bank receives settlement funds.
When reviewing the workflow, confirm that customer identifiers, invoice references, transaction status, and settlement information can be traced across these systems. Appropriate integrations help exchange transaction details with accounting records and reduce the need to re-enter information between applications.
Credit card processing also connects with broader accounts receivable activities. Accounts Receivable Payment Processing describes the activities involved in receiving, recording, and applying customer payments. In Sage 100, accurate payment application helps keep customer balances current and supports reliable aging reports.
Fees, Settlements, and Reconciliation
Card processors commonly charge transaction fees based on contractual pricing and transaction characteristics. These fees mean the bank deposit may be lower than the gross amount charged to customers. Finance teams should reconcile the gross transaction total, processing fees, refunds, chargebacks, and net settlement rather than matching only the deposit amount to the original invoices.
For example, assume a business processes $10,000 in card transactions and the processor deducts $250 in fees, with no refunds or other adjustments. The expected net settlement is $9,750. The accounting records should account for the $10,000 customer payment activity, the $250 processing expense, and the $9,750 bank deposit according to the company's accounting configuration.
Bank Reconciliation compares recorded cash activity with bank statement transactions. For card settlements, finance staff should use processor settlement reports to explain differences in timing, fees, refunds, and transaction batches. A deposit received the next business day may relate to card payments recorded on the previous day, so settlement dates and transaction dates should be reviewed separately.
Controls, Refunds, and Customer Collections
Strong controls begin with using a supported payment provider, limiting access to payment functions, and following applicable card-security requirements. Staff should verify transaction status before treating an invoice as paid, and refunds or voids should be recorded against the original transaction wherever the system supports that workflow. Reconciliation procedures should also identify duplicate entries, unmatched settlements, and chargebacks for timely review.
Card payments can reduce outstanding balances, but not every customer pays by card. Finance teams may also rely on bank transfers, checks, or other methods. A clear Credit Collections Framework helps define follow-up timing, dispute handling, and escalation for invoices that remain unpaid. The broader collections process should use current customer balances so staff can focus on genuinely overdue receivables.
For businesses looking to streamline related receivables activities, AR Automation Software can support payment matching and collection follow-ups, while cash application processes help connect incoming funds to the correct invoices. These workflows complement card processing by improving the visibility of customer balances and unapplied cash.
Choosing and Managing a Payment Workflow
Before enabling a payment solution, verify compatibility with the installed Sage 100 version, the modules in use, and the merchant provider's supported transaction types. Confirm whether the workflow supports the required sales and receivables scenarios, including invoice payments, deposits, partial payments, voids, and refunds. Also review how transaction fees are posted and which reports are available for settlement reconciliation.
Teams comparing document and transaction automation may consult Invoice Software 2025: AI-Ready AP & Billing Guide. Although invoice processing and card payments serve different functions, both benefit from accurate transaction data, consistent validation, and traceable posting. For purchasing controls, a purchase order records an authorized procurement commitment; it is distinct from a customer's card payment and should remain linked to the relevant purchasing and payable records.
Where a business uses multiple finance workflows, the Hyperbots Platform supports finance and accounting automation, while its Customer Payment Processing workflow conceptually covers how customer payments are received and handled. The related Order-to-Cash Process: Complete Guide to O2C Automation explains how payment receipt fits into the wider cycle of invoicing, receivables collection, and cash application.
Purchase approvals also matter to the wider financial control environment. A purchase order should follow the company's authorization rules before a supplier commitment is made, and teams can learn about process design through Automate Purchase Order Processing. These procurement controls are separate from credit card acceptance but contribute to consistent financial records and oversight.
Summary
Sage 100 Credit Card Processing connects customer card transactions with receivables records and settlement activity. A well-managed workflow distinguishes authorization from settlement, records fees and refunds accurately, and reconciles processor reports to bank deposits. Businesses should confirm compatibility with their Sage 100 environment, establish clear access and refund controls, and regularly review unmatched transactions. These practices help maintain accurate customer balances, dependable cash reporting, and better visibility into the company's financial position.
