Evaluate computerised accounting systems
Assess how software can improve recording and reporting while recognising implementation, accuracy and access risks.
Cambridge International AS & A Level Accounting 9706, 2026–2028 syllabus, Version 2. These lessons cover Topic 1.2 only. The 2029 syllabus has a separate document and is not mapped here. Practice is self-checked, not an official Cambridge grade; timed-paper practice and human subject-teacher review remain outstanding.
Before you begin
- Topic 1.1 introduces business forms and finance. In these lessons, keep each transaction tied to its source evidence and record both sides of its effect.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
A program posts every sales entry correctly, but the staff enter the wrong customer amounts. What is the likely result?
What you will learn
- Explain the use of computerised accounting systems
- Evaluate advantages and disadvantages
- Avoid assuming that automation guarantees correct records
A computerised system processes accounting data
A computerised accounting system records transactions, updates accounts and can produce reports. It can process routine entries quickly, apply configured rules consistently and make information available to authorised users.
It may reduce repeated manual calculations and help search or analyse records. These benefits depend on accurate input, suitable configuration, trained users, reliable equipment and continuing controls.
Technology introduces costs and dependencies
Set-up, subscription, migration and training take time and money. Incorrect opening balances, duplicate imports, poor coding or an outage can affect many records. A system can reproduce an input error quickly; automation does not replace review.
Choose a system for the business's transaction volume, reporting needs, budget and staff. Keep a clear process for checking transactions, reconciling balances and recovering records after a failure.
Pause and explain
What should a business do after importing opening balances into a new system?
Worked example
A small retailer replaces spreadsheets with a cloud accounting service. Give two potential benefits and one implementation risk.
Show the worked solution
- Routine entries and reports may be processed more quickly.
- Authorised staff may access current information from different locations.
- Opening-balance errors or poorly configured tax/account codes can flow into reports, so migration must be checked.
Answer The retailer may save time on routine recording and give authorised staff more timely access. It must verify migrated balances and account settings because setup errors can contaminate later reports.

Test this topic →From guided practice to a new situation
Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A system creates an invoice from a sales order but the order's quantity is wrong. Explain why the invoice may also be wrong.
Give me a hint
Trace how information flows from the original input.
Compare my reasoning
- The invoice uses data from the sales order.
- An incorrect quantity in the source record is carried into the generated invoice.
- Validate the order and compare the invoice with evidence before dispatch.
The system may repeat the incorrect quantity because the source input is wrong. Validate the order and check the invoice; automation alone does not correct the source.
Look for these in your work
- Input traced
- Error propagation explained
- Control proposed
A firm considers a system that costs $2,000 to set up and $600 each year, replacing 10 hours of manual processing each month. What additional evidence is needed before recommending it?
Give me a hint
Time saved alone is not the entire decision.
Compare my reasoning
- Estimate the value of staff time saved and compare it with setup and annual costs.
- Check migration, training, maintenance, security and outage risks.
- Consider whether the reports and workflow meet the firm's actual needs.
Calculate realistic time savings and total costs over a chosen period, then assess fit, migration, training, security and resilience. The 10 hours saved cannot by itself prove that the system is worthwhile.
Look for these in your work
- Benefits quantified
- Total costs considered
- Operational fit and risks included
After a software update, the sales ledger total no longer agrees with the control account. Give a safe sequence for investigating it.
Give me a hint
Preserve evidence, compare totals and trace the change.
Compare my reasoning
- Retain the before-and-after reports and do not overwrite the original records.
- Reconcile the control account to individual customer balances and compare the update/import log.
- Identify and correct the supported cause, then rerun the reconciliation.
Keep the original evidence, reconcile control and individual ledger balances, inspect the update/import evidence, correct the verified cause and rerun the check. Do not force a balancing entry without finding the discrepancy.
Look for these in your work
- Evidence preserved
- Control and detail compared
- Cause checked before correction
Common mistakes
- Claiming software makes accounts automatically accurate
- Ignoring subscriptions, training and migration
- Assuming every employee should have full access
