SaaS vs ERP

SaaS and ERP are acronyms that are commonly found together when comparing different ways to implement an ERP system - but standalone SaaS providers are becoming a popular way to overcome common disadvantages found in ERPs. For SaaS businesses, adopting ERP for SaaS companies is an increasingly attractive option due to its tailored approach to cloud-based software deployment. Clearing up the confusion surrounding “SaaS vs ERP” is crucial to understanding the value of SaaS platforms and the benefits of e-procurement systems. Simply put, software as a service (SaaS) is any subscription-based software that is hosted online from a central provider location. Enterprise resource planning (ERP) systems differ in that they can be owned and hosted on local servers (also referred to as “on-premises”) within an organization, but can sometimes also be delivered as SaaS products hosted online.So, why do people sometimes compare the advantages of standalone SaaS solutions against ERPs - if ERPs can be SaaS products themselves in many circumstances? It comes down to a consideration between locking into a single ERP system vs the diverse set of tools offered by combining services from a variety of different SaaS providers.

Weighing the advantages and disadvantages of procurement ERP software

One of the main appeals and advantages of procurement ERP software is their ability to deliver many types of tools on a single platform. These tools can include:

• Finance Resource Management• Supply Chain Management• Human Resource Management• Customer Resource Planning• Manufacturing Resource Planning

ERPs optimize business processes by sharing accurate information with relevant parties throughout an organization in a timely manner, eliminating redundant manual operations, and removing the clutter of duplicate records from the system.Some of the most noticeable benefits of procurement ERP software in an organization include a noticeable reduction in time spent on reporting, faster customer service response times, and improved internal control over business workflows.

Comparing ERP vs SaaS

However, while getting all of these tools in one package sounds great in theory, the diversity in what these systems can offer is the exact reason that so many disadvantages and problems with ERP platforms exist.

ERP Problems and Disadvantages

There are several common disadvantages and customization issues associated with ERP implementation:The average cost of implementing an ERP is extremely high. Small businesses can expect to pay upwards of $10,000 for a basic implementation, mid-sized businesses between $150,000 and half a million, while large enterprises are looking at a multi-million dollar investment for implementation.

There are several disadvantages and problems with ERP systems

And that’s just the upfront price. Don’t get blindsided by the additional costs from paying consultants, managing human resources, acquiring licences, sustaining recurring fees, and paying for training sessions that are needed to cover for another drawback...One of the driving causes behind ERP failure is their complexity. Because they offer so many different tools, ERPs are difficult for employees to learn and use. During implementation, teams will often struggle to adapt to the new tools, and sometimes employees and managers end up being replaced due to this challenge. The difficulty doesn’t end there, though…ERP implementation timelines are notorious for being drawn out. The benefits of procurement ERP software will not be visible immediately. In fact, it can take years before an ERP system begins providing its return on investment. What’s worse is that a failed ERP implementation carries the ever-present risk of never actually providing its benefit, resulting in catastrophic financial results for the company.

Mixing standalone SaaS tools vs a single ERP provider

A sometimes overlooked approach to selecting business applications is considering the benefits of multi-sourcing several dedicated SaaS tools vs locking in with a single ERP provider. Adopting an eclectic software strategy helps to mitigate the problems traditionally associated with ERPs:SaaS providers are infinitely more affordable than their ERP counterparts. Not only do these tools cost less to implement, but other than standard monthly subscription fees, additional charges are few and far between on SaaS platforms. For a fraction of an ERPs cost, it’s common for SaaS providers to offer customization and integration work to fit your company’s specific needs as well...SaaS solutions are more agile in changing markets. The time it takes for cumbersome ERPs to develop their systems often lags far behind the latest advancements of certain service providers. While ERPs offer a wide range of tools, it can take months or years for those tools to cater to the evolving needs of the businesses that use them. Finally...Picking standalone SaaS tools vs an ERP solution avoids vendor lock-in. Back-pedaling out of an ERP buy-in is nearly impossible due to the high cost and slow nature of their implementation. In contrast, switching from one SaaS provider to another is a great way to keep your business strategy flexible and adaptable as competitors add new features and tools to the services they offer.

Traditional ERP vs Standalone SaaS-1

SaaS ERP 

SaaS ERP is a software-as-a-service enterprise research planning system, which is usually a cloud-based system. 

SaaS ERP Software 

SaaS ERP software provides cloud-based hosting functionality, a subscription model, a high level of scalability, and automatic updates. It is a cost-effective solution that lowers costs compared to traditional ERP systems. It is also easy to implement and set up. 

ERP software's main features include financial management (accounting process automation, expense tracking), supply chain management features (inventory tracking), and HR management features to take care of payroll processing. 

Overall, ERP systems are designed to manage a wide range of business processes. 

SaaS Procurement 

SaaS procurement is a software solution dedicated to managing procurement within the organization. 

SaaS Procurement Software 

SaaS procurement tools enhance the procurement process and help organizations to streamline it by offering a variety of useful functionality. The main features procurement software solutions offer include sourcing tools, supplier management and inventory management tools, supplier collaboration tools, automation functionality, and powerful analytics. 

Also, keep in mind that a good SaaS procurement software should offer integration with your current or other popular ERP systems to streamline the processes even further.

While it’s nice that some ERPs offer procurement tools, a lack of dedicated development often makes them sub-optimal when compared to SaaS providers that focus only on e-procurement.That’s not to say that ERPs can’t deliver effective tools in their software suites, but a simple comparison shows that the advantages of e-procurement tools can be acquired for far less through SaaS providers.

‍The benefits of dedicated e-procurement include:

• Reducing costs• Increasing productivity• Internal process control• Improving spend visibility• Digitally streamlining processes

Frequently Asked Questions

Should a growing business choose a traditional ERP module or SaaS procurement software?
A growing business should generally lean toward SaaS procurement software over adding a procurement module to a traditional ERP, mainly because of implementation time, cost, and flexibility. Traditional ERP procurement modules often require significant IT involvement and longer implementation timelines to configure, while SaaS procurement platforms are typically faster to deploy and easier to adjust as needs change. Some businesses use a hybrid approach, running SaaS procurement software that integrates with their existing ERP for accounting, which captures faster setup on the purchasing side while keeping financial data centralized in the ERP.
Is Tradogram a good SaaS spend management option for a company that isn't enterprise-sized?

Tradogram is built specifically for this middle segment: organizations with roughly 50 to 500 employees and $10 million to $500 million in revenue that need real spend control but don't have the IT resources or budget for a large enterprise deployment. As a SaaS platform, it avoids the infrastructure and implementation overhead traditional on-premises or enterprise ERP-based procurement tools require, while still offering configurable approval workflows, budget tracking, and supplier management. It also connects to common accounting platforms like QuickBooks and Xero natively, which matters for companies that already have an accounting system and don't want to replace it just to get better spend control.

What costs should you compare when choosing between an ERP procurement module and SaaS software?

Look beyond the license fee. For an ERP module, include implementation consulting, customization, upgrades, and the internal IT time needed to maintain it. For SaaS procurement software, include the subscription, setup and configuration, integration with your ERP or accounting system, and training. Also count the cost of poor adoption: a module that's hard to use often leads to off-system purchasing, which weakens the controls you paid for. Comparing total cost over several years gives a fairer picture than comparing upfront prices.

How do SaaS procurement tools stay in sync with an ERP?

Through native integrations or APIs that pass data between the two systems automatically. Typically, suppliers, general ledger codes, and budgets flow from the ERP into the procurement tool, while approved purchase orders, receipts, and matched invoices flow back into the ERP for payment and reporting. Agree on which system owns each type of record, so updates happen in one place. Testing the sync with real transactions before launch catches mapping errors, such as mismatched cost centers, early.
