What is an office manual?
An office manual is a book that records, in summarised form, all the activities done in an organisation.
- Other name: it is also called a procedure manual.
- Who produces it: every organisation produces its own manual.
- What it contains: the steps for each task, who does it and in what order.
- Who uses it: new and old staff use it to check how a task should be done.
Why is office procedure important?
Office procedure is important because it makes office work orderly, faster and cheaper to run.
- Lower cost: it reduces the general cost of operation.
- Easy training: it allows for easy training of new staff.
- Better performance: it enhances the performance of old staff.
- Better flow of work: it helps work move smoothly between offices and departments.
- Better coordination: it helps staff and departments work together.
What are examples of office procedures?
Office procedures cover any regular task that follows set steps.
- Handling incoming mail: receiving, sorting, opening, date-stamping, recording and passing letters to the right person.
- Handling outgoing mail: drafting, typing, signing, copying, recording and posting letters.
- Filing: arranging documents in order so they can be found quickly.
- Receiving visitors: welcoming, recording and directing visitors to the right officer.
- Preparing an invoice: writing down the goods or services supplied and the amount to be paid.
Steps for handling incoming mail
- Receive the mail.
- Sort it into letters, parcels and other items.
- Open it and take out the contents.
- Stamp the date of receipt on each letter.
- Record it in the mail register.
- Pass it to the person or department concerned.
What is an invoice?
An invoice is a document sent by a seller to a buyer that lists the goods or services supplied and the amount to be paid.
- Seller: the business that supplied the goods or services.
- Buyer: the customer who must pay.
- Purpose: it is a request for payment and a record of the sale.
How do you prepare an invoice?
An invoice is prepared in eight steps, from the company’s contact details to the accepted methods of payment.
- Write your contact information: write or type the company’s details on a sheet of paper, spreadsheet or other electronic record-keeping system. Include an email address and phone number for customer questions.
- Create a unique invoice number: use letters, numbers or both.
- A simple number is “Job-001”.
- A fuller number is “Smith-Job-001”. It suits repeat customers because it carries their last name and a job number.
- Future invoices should have unique, sequential job numbers. This makes sorting a client’s job history easier.
- Date the invoice: the sooner you invoice clients, the sooner you can get paid.
- Describe the work performed: use separate lines to itemise each service or product.
- Give the type and quantity of materials used.
- For services, give clear details of the scope of work and the hours spent on each part.
- Find the subtotal: add up the total quantities of each material, product and service supplied.
- Work out the final job cost: add the sales tax to the subtotal and write the result at the bottom of the invoice. Use legible, boldface type so customers know exactly how much to pay.
- State the payment terms: say when you want to be paid (see the table below).
- State the payment methods: tell customers which methods you accept, such as cash on delivery (COD), cash, cheque or credit card.
What are common payment terms?
| Term | Meaning |
|---|---|
| NET 15 | Payment is due in 15 days. |
| NET 30 | Payment is due in 30 days. |
| Due on Receipt | Payment is due when the customer receives the invoice. |
| COD | Cash on delivery: the customer pays when the goods arrive. |
What does a simple invoice look like?
| Item | Quantity | Unit price (₦) | Amount (₦) |
|---|---|---|---|
| A4 paper (ream) | 10 | 5,000 | 50,000 |
| Biro (box) | 5 | 1,500 | 7,500 |
| Subtotal | 57,500 |
