The Purchasing Information System can be used at a variety of levels in the decision-making process as an instrument for monitoring, controlling and planning your business operations. It is a flexible tool for collecting, aggregating and analyzing data from Purchasing The purchase order process consists of several compliance checkpoints and approval/input tasks to ensure timely PO processing. Here are the most common purchase order process steps:
a) PO creation: Purchase orders are created from approved purchase requisitions
b) Approval flow: POs are approved after budget and document verification
c) PO dispatch: Once approved, purchase orders are forwarded to the selected vendor
d)Binding contract: A legally binding contract is invoked once the vendor accepts the PO
e)Goods delivery: The vendor delivers goods, and the buyer does a quality check and notifies the sender in case of defects
f) Three-Way matching: Buyer performs three-way matching (with purchase request, PO, and invoice)
g) PO closure: After PO matching, if there are no discrepancies, purchase orders are closed
Purchase order process flow
The purchase order process flow is the lifecycle of a purchase order from order creation to closure. A predefined purchase order process flow allows the purchasing team to process a PO without missing any steps, and follow it up easily to avoid delays. This purchase order process flow depicts the action steps in PO processing as follows:
1. Create a purchase order
2. Send out multiple requests for quotation (RFQ)
3. Analyze and select vendor
4. Negotiate contract and send PO
5. Receive goods/services
6. Receive and check invoice (3-Way Matching)
7. Authorize invoice and pay vendor
8. Record keeping

Outsourcing is the process of engaging a third-party individual or organization outside of your company, either locally or internationally, to handle certain business activities for you. It is a common business practice that allows companies of all sizes to grow as and when they need it, without major risk or investment.
IT outsourcing is the practice of hiring resources outside of an organization to handle certain information technology functions. Companies often outsource data storage because it is cheaper to contract a third party than to buy and maintain their own data storage devices and facilities.
The most commonly outsourced IT functions are:
i. Web development
iii. Software and application development
iv. Website/application maintenance or management
v. Technical support
vi. Database development and management
IT Outsourcing Examples
The individual or company that becomes your outsourcing partner can be located anywhere in the world one block away from your office or on another continent.
Why do companies outsource? Here are a few common reasons that can help explain the trend:
1. To reduce cost. More often than not, outsourcing means saving money. This is often due to lower labor costs, cheaper infrastructure, or an advantageous tax system in the outsourcing location.
2. To access skills that are unavailable locally. Resources that are scarce at home can sometimes be found in abundance elsewhere, meaning you can easily reach them through outsourcing.
3. To better use internal resources. By delegating some of your business processes to a third party, you’ll give your in-house employees the opportunity to focus on more meaningful tasks.
4. To accelerate business processes. When you stop wasting time on mundane, time-consuming processes, you’ll be able to move forward with your core offering a lot faster.
