Invoices Bills and Payments

1The records behind each payment

A financial transaction is an event that changes the company's financial records. An invoice, supplier bill, payment, refund, or loan receipt can create a transaction. Each transaction needs a date, amount, explanation, and supporting document. The document tells the reviewer what happened; the accounting entry records its financial effect.

An invoice requests payment from a client. A bill records an amount owed to a supplier. A payment settles some or all of an amount owed. Before recording a payment, establish whether the invoice or bill already exists. Otherwise a bank transaction can become a second entry for activity recorded earlier.

Accounts receivable is money clients owe for amounts already recorded as due. Accounts payable is money owed to suppliers for bills already recorded. These balances connect the original charge with its later payment. A client can have several unpaid invoices. Apply a payment to the invoices the client intended to pay, using the payment explanation and the remaining balances.

For supplier payments, retain the supplier's invoice number. Search for an existing bill before entering another copy from an email attachment. A repeated invoice number, supplier, date, and amount may indicate a duplicate. Investigate rather than relying on the document's filename or the date it was downloaded.

An MSP's service system supplies billing evidence. Confirm the service period, agreement price, approved additions, and any project completion conditions before creating the invoice. The accounting system then records the approved invoice. Both records must use a consistent client identity so later payments can be applied accurately.

2The chart of accounts

The chart of accounts is the list of categories used in the accounting records. An account collects related transactions, such as bank cash, accounts receivable, software delivery costs, or office rent. A useful chart supports the decisions you need to make without creating a separate account for every client and supplier.

Five broad account types explain most of the entries you will encounter. Assets are resources the business owns or controls, such as cash and receivables. Liabilities are amounts or obligations the business owes, such as supplier bills and loans. Equity is the owners' residual interest after liabilities are subtracted from assets. Revenue records amounts earned from providing services or products. Expenses record costs recognized for the reporting period.

A client name tells you who owes money. A revenue account tells you the kind of work that earned the money. Those are different questions. Creating a revenue account for each client can make the chart hard to maintain. Ask the accountant which customer, service, project, or reporting features should carry the additional detail.

Use the approved account definitions consistently. A supplier name does not settle the classification. The same supplier might provide a client's software licenses and the MSP's internal software. The first purchase may be classified as a direct delivery cost; the second may be overhead under the company's policy. Read what was purchased and why.

Keep an account guide with a short definition, typical examples, and the person who resolves uncertain entries. A question about classification is normal. Guessing repeatedly creates reports that appear precise while mixing unlike costs. The admin manager should flag uncertain items before the monthly close and propose a classification supported by the document.

3Debits, credits, and balanced entries

Double-entry accounting records the financial effect of a transaction in at least two accounts. Total debits equal total credits for each entry. A debit and a credit are the two sides of an accounting entry. The words do not mean good and bad, and their effect depends on the account type.

For the ordinary accounts in the following table, debits increase assets and expenses. Credits increase liabilities, equity, and revenue. The opposite entry reduces the account. Some accounts, such as accumulated depreciation, offset another account and need separate explanation. Use the basic table to understand ordinary entries rather than treating it as a rule for every possible account.

Ordinary account type	Increase	Decrease
Asset	Debit	Credit
Expense	Debit	Credit
Liability	Credit	Debit
Equity	Credit	Debit
Revenue	Credit	Debit

In a practice example, an MSP earns $900 for completed support and invoices the client. The entry increases accounts receivable with a $900 debit and increases revenue with a $900 credit. When the client pays, the entry increases cash with a $900 debit and reduces receivables with a $900 credit. Both entries balance, and revenue has been recorded once.

A supplier bill for $300 of software used during the month increases the relevant expense with a $300 debit and accounts payable with a $300 credit. Paying that bill reduces accounts payable with a $300 debit and cash with a $300 credit. Expense is recorded once, even though there are two events.

You usually create these entries through invoice, bill, and payment forms rather than typing the debit and credit yourself. Understanding the entry helps you spot an incorrect account or duplicate. A journal entry records debits and credits directly. Use journal entries according to the accountant's procedures, particularly for receivables and payables where an adjustment must also connect to the client or supplier records.

4Bank feeds and matching

A bank feed imports bank or card activity into the accounting system. An imported line shows that money moved. The line alone may not explain whether the movement paid an existing bill, settled a client invoice, transferred money between accounts, or repaid borrowing.

Matching connects an imported payment to a transaction already recorded. Categorizing creates or assigns the accounting treatment for activity that still needs recording. The available actions depend on the tool and the record. Before accepting a suggested match, check the amount, payee or client, date, account, and underlying invoice or bill.

A payment may combine several invoices. A deposit may combine several client payments. Payment processing fees can cause the bank deposit to be smaller than the clients' total payments. Preserve the gross payments and identify the fees separately under the accountant's procedure. Treating the net deposit as the entire collection can leave invoices appearing unpaid or understate fees.

A transfer between company bank accounts changes where cash is held. It does not create service revenue or an operating expense. Match the withdrawal and deposit to the same transfer. A card payment similarly settles the card liability; the purchases charged to the card must already have their own classifications.

A bank rule can help process repeated activity, but a rule based only on a supplier name can assign the wrong account when the supplier provides several kinds of products. Review what the rule does and retain a method for examining exceptions. Bank reconciliation later checks the accounting balance against the bank statement; accepting every feed item is not a substitute for that reconciliation.

For an unexpected payment destination change, verify the request through a known contact method before updating vendor details. Keep evidence of the verification and obtain the required approval. A genuine bill can still be paid to the wrong destination if the change request was fraudulent or mistaken.

5Credits, refunds, and corrections

A credit reduces an amount charged to a client or owed to a supplier. A refund returns money. A credit can exist before money is returned, so the two records should remain connected. Record the reason, the original invoice or bill, and the approval required by company policy.

If an invoice charged the wrong amount, establish whether the error concerns the price, quantity, service period, or tax treatment. Correct the accounting and billing records through the approved process. Changing a completed prior month may change reports the CEO already reviewed. Record the correction and identify the affected period.

When a client disputes a charge, the invoice may remain legally due while the business investigates. That dispute still matters for collection expectations. Keep the dispute status with the collection record. Do not assume the disputed amount will arrive on its original due date merely because the invoice remains in the ledger.

Payment allocation errors can create misleading overdue lists. A payment applied to the wrong client can make one client appear overdue and another appear overpaid. Compare the remittance information, which explains the invoices being paid, with the accounting application. Correct the allocation without creating a new payment for money already received.

The admin manager prepares the proposed correction and its evidence. The CEO approves unusual credits or refunds under the agreed rules. The accountant handles corrections requiring accounting judgment or changes to closed periods. Maintain the record of the original event and the correction so a later reviewer can follow the sequence.

6Practice example: a partial payment

This hypothetical exercise uses accrual accounting and excludes tax. An MSP earns and invoices $1,200 for a completed service. The client pays $800 toward that invoice. A supplier bill records $250 of licenses used for the service, and the MSP pays the full bill.

Create a row for each of the four events. Name the two accounts changed by each event and whether each account increases or decreases.
Calculate the remaining receivable and payable. Calculate the net cash change from the payments.
Calculate the revenue and expense recorded from these events. Explain why neither payment records the same revenue or expense again.
Suppose the $800 deposit appears in the bank feed. State the record you should find before accepting or categorizing the deposit.
Identify the evidence the reviewer needs for each event, including the partial payment allocation.

Check your work

The invoice increases receivables and revenue by $1,200. The client payment increases cash by $800 and reduces receivables by $800. The supplier bill increases expense and payables by $250. Paying the bill reduces cash and payables by $250.

The remaining receivable is $1,200 minus $800 = $400. The payable is $250 minus $250 = $0. Net cash increases by $800 minus $250 = $550. Recorded revenue is $1,200 and recorded expense is $250. The payments settle balances rather than create the original activity again.

Find the recorded client payment and original invoice before processing the imported deposit. Confirm the $800 allocation and the $400 remaining balance. Evidence includes service approval, invoice, supplier bill, remittance detail, and payment confirmation. Each debit and credit pair must balance.

7Your company entry review

The admin manager selects an approved client invoice, its payment, a supplier bill, and its payment from the same completed period. Inspect the accounting effect of each record with the available transaction details. If the system view is unfamiliar, ask the accountant to show how the form reaches the accounts instead of inventing a menu path.

Prepare a table with the source document, date, accounts changed, amount, and remaining client or supplier balance. Compare the payments with the bank records. Add an uncertain classification or match to a short exception list with the proposed next step.

The CEO checks that recorded amounts agree with the evidence and that each payment clears the intended record. Agree who can approve credits, refunds, account changes, and vendor banking changes. The deliverable is an entry review and a compact account guide for the categories used in the selected transactions.

Keep client identifiers and payment details in approved finance files. Shared course notes can describe the method and the unresolved question without reproducing banking information. In Session 3, the focus moves from individual records to the profit and loss report built from those records.

Going deeper

A balanced entry can still be wrong. Recording a payment to the wrong expense account can produce equal debits and credits while misclassifying the cost. A trial balance lists the ledger account balances and checks debit and credit totals. The totals help identify some recording problems, but supporting documents and reconciliations establish whether the entries describe the real transactions. Special accounts and adjustments require the accountant's policy; avoid a generic journal entry that leaves customer or supplier balances disconnected.
