Sales Order Process Flowchart
Manual Sales Order Processing
 Begins with a customer placing an order
 The sales department captures the essential details
on a sales order form.
 The transaction is authorized by obtaining credit
approval by the credit department.
 Sales information is released to:
 Billing
 Warehouse (stock release or picking ticket)
 Shipping (packing slip and shipping notice)
 The merchandise is picked from the Warehouse
and sent to Shipping.
 Stock records are adjusted.
 The merchandise, packing slip, and bill of lading
are prepared by Shipping and sent to the customer.
 Shipping reconciles the merchandise received from
the Warehouse with the sales information on the
packing slip.
 Shipping information is sent to Billing. Billing
compiles and reconciles the relevant facts and
issues an invoice to the customer and updates the
sales journal. Information is transferred to:
 Accounts Receivable (A/R)
 Inventory Control
Manual Sales Order Processing
 A/R records the information in the customer’s
account in the accounts receivable subsidiary ledger.
 Inventory Control adjusts the inventory subsidiary
ledger.
 Billing, A/R, and Inventory Control submits summary
information to the General Ledger dept., which then
reconciles this data and posts to the control accounts
in the G/L.

Cash Receipts Flowchart
Manual Cash Receipts Processes
 Customer checks and remittance advices are
received in the Mail Room.
 A mail room clerk prepares a cash prelist and sends the
prelist and the checks to Cash Receipts.
 The cash prelist is also sent to A/R and the Controller.
 Cash Receipts:
 verifies the accuracy and completeness of the checks
 updates the cash receipts journal
 prepares a deposit slip
 prepares a journal voucher to send to G/L
 A/R posts from the remittance advices to the
accounts receivable subsidiary ledger.
 Periodically, a summary of the postings is sent to
G/L.
 G/L department:
 reconciles the journal voucher from Cash Receipts
with the summaries from A/R
 updates the general ledger control accounts
 The Controller reconciles the bank accounts.
Manual Cash Receipts Processes
Summary of Internal Controls
Authorization Controls
 Proper authorization of transactions
(documentation) should occur so that only valid
transactions get processed.
 Within the revenue cycle, authorization should take
place when:
 a sale is made on credit (authorization)
 a cash refund is requested (authorization)
 posting a cash payment received to a customer’s account
(cash pre-list)
Segregation of Functions
Three Rules
1. Transaction authorization should be separate
from transaction processing.
2. Asset custody should be separate from asset
record-keeping.
3. The organization should be so structured that
the perpetration of a fraud requires collusion
between two or more individuals.
Segregation of Functions
 Sales Order Processing
 credit authorization separate from SO processing
 inventory control separate from warehouse
 accounts receivable sub-ledger separate from general ledger
control account
 Cash Receipts Processing
 cash receipts separate from accounting records
 accounts receivable sub-ledger separate from general ledger
Supervision
Often used when unable to enact
appropriate segregation of duties.
Supervision of employees serves as
a deterrent to dishonest acts and is
particularly important in the
mailroom.
Accounting Records
 With a properly maintained audit trail, it is
possible to track transactions through the
systems and to find where and when errors
were made:
 pre-numbered source documents
 special journals
 subsidiary ledgers
 general ledger
 files
Access Controls
 Access to assets and information (accounting
records) should be limited.
 Within the revenue cycle, the assets to protect
are cash and inventories and access to records
such as the accounts receivable subsidiary ledger
and cash journal should be restricted.
Independent Verification
 Physical procedures as well as record-keeping should be
independently reviewed at various points in the system to
check for accuracy and completeness:
 shipping verifies the goods sent from the warehouse
are correct in type and quantity
 warehouse reconciles the stock release document
(picking slip) and packing slip
 billing reconciles the shipping notice with the sales
invoice
 general ledger reconciles journal vouchers from
billing, inventory control, cash receipts, and accounts
receivable
Automating the Revenue Cycle
 Authorizations and data access can be
performed through computer screens.
 There is a decrease in the amount of paper.
 The manual journals and ledgers are changed
to disk or tape transaction and master files.
 Input is still typically from a hard copy
document and goes through one or more
computerized processes.
 Processes store data in electronic files (the tape
or disk) or prepare data in the form of a
hardcopy report.
Automating the Revenue Cycle
 Revenue cycle programs can include:
 formatted screens for collecting data
 edit checks on the data entered
 instructions for processing and storing the data
 security procedures (passwords or user IDs)
 steps for generating and displaying output
 To understand files, you must consider the record
design and layout.
 The documents and the files used as input sources
must contain the data necessary to generate the
output reports.
Computer-Based Accounting Systems
 CBAS technology can be viewed as a continuum
with two extremes:
 automation - use technology to
improve efficiency and effectiveness
 reengineering – use technology to
restructure business processes and
firm organization
Example: Automated Batch Sales
Reengineering Sales Order Processing Using
Real-Time Technology
 Manual procedures and physical documents are
replaced by interactive computer terminals.
 Real time input and output occurs, with some master
files still being updated using batches.
 Real-time - entry of customer order, printout of
stock release, packing slip and bill of lading; update
of credit file, inventory file, and open sales orders
file
 Batch - printout of invoice, update of closed sales
order (journal), accounts receivable and general
ledger control account
Real-time Sales Order
Advantages of Real-Time
Processing
 Shortens the cash cycle of the firm by reducing the
time between the order date and billing date
 Better inventory management which can lead to a
competitive advantage
 Fewer clerical errors, reducing incorrect items
being shipped and bill discrepancies
 Reduces the amount of expensive paper documents
and their storage costs
Reengineered Cash Receipts
 The mail room is a frequent target for reengineering.
 Companies send their customers preprinted
envelopes and remittance advices.
 Upon receipt, these envelopes are scanned to
provides a control procedure against theft.
 Machines are open the envelopes, scan remittance
advices and checks, and separate the checks.
 Artificial intelligence may be used to read
handwriting, such as remittance amounts and
signatures.
Automated Cash Receipts
Point-of-Sale Systems
 Point of sale systems are used extensively in
retail establishments.
 Customers pick the inventory from the shelves and
take them to a cashier.
 The clerk scans the universal product code
(UPC). The POS system is connected to an
inventory file, where the price and
description are retrieved.
 The inventory levels are updated and reorder needs
can immediately be detected.
Point-of-Sale Systems
 The system computes the amount due. Payment
is either cash, check, ATM or credit card in most
cases.
 No accounts receivables
 If checks, ATM or credit cards are used, an on-line
link to receive approval is necessary.
 At the end of the day or a cashier’s shift, the
money and receipts in the drawer are reconciled
to the internal cash register tape or a printout
from the computer’s database.
 Cash over and under must be recorded
Computerized POS
Reengineering Using EDI
 EDI helps to expedite transactions.
 The customer’s computer:
 determines that inventory is needed
 selects a supplier with whom the business has a
formal business agreement
 dials the supplier’s computer and places the order
 The exchange is completely automated.
 No human intervention or management

Reengineering Using the
Internet
 Typically, no formal business agreements exist as
they do in EDI.
 Most orders are made with credit cards.
 Mainly done with e-mail systems, and thus a
turnaround time is necessary
 Intelligent agents are needed to eliminate this time
lag.
 Security and control over data is a concern with
Internet transactions.
CBAS Control Considerations
 Authorization - in real-time systems,
authorizations are automated
 Programmed decision rules must be closely
monitored.
 Segregation of Functions - consolidation of tasks
by the computer is common
 Protect the computer programs
 Coding, processing, and maintenance should be
separated.
 Supervision - in POS systems, the cash register’s
internal tape or database is an added form of
supervision
 Access Control - magnetic records are vulnerable to
both authorized and unauthorized exposure and
should be protected
 Must have limited file accessibility
 Must safeguard and monitor computer programs
CBAS Control Considerations
 Accounting Records - rest on reliability and
security of stored digitalized data
 Accountants should be skeptical about the
accuracy of hard-copy printouts.
 Backups - the system needs to ensure that backups
of all files are continuously kept
 Independent Verification – consolidating
accounting tasks under one computer
program can remove traditional independent
verification controls. To counter this problem:
 perform batch control balancing after each run
 produce management reports and summaries for
end users to review
CBAS Control Considerations
PC-Based Accounting Systems
 Used by small firms and some large decentralized
firms
 Allow one or few individuals to perform entire
accounting function
 Most systems are divided into modules controlled
by a menu-driven program:
 general ledger
 inventory control
 payroll
 cash disbursements
 purchases and accounts payable
 cash receipts
 sales order
PC Control Issues
 Segregation of Duties - tend to be inadequate
and should be compensated for with increased
supervision, detailed management reports, and
frequent independent verification
 Access Control - access controls to the data
stored on the computer tends to be weak;
methods such as encryption and disk locking
devices should be used
 Accounting Records - computer disk failures
cause data losses; external backup methods
need to be implemented to allow data recovery
