Build vs. Buy: Custom Construction Integrations vs. Off-the-Shelf Connectors

For a construction company using Procore alongside accounting, ERP, or other business systems, there eventually comes a practical question:
Should we buy an existing connector, or build a custom Procore integration?
There is no universal answer.
An off-the-shelf connector may be the right choice when a company's workflow is relatively standard and the required systems are already supported.
A custom integration may make more sense when the company has unique cost structures, multiple entities, complex approval workflows, or systems that do not work well with available connectors.
The decision should therefore be based on the company's actual workflow rather than simply choosing the option that appears easier or cheaper at first.
What Are Off-the-Shelf Procore Connectors?
An off-the-shelf connector is a prebuilt integration designed to connect Procore with another software system.
Instead of developing the connection from the beginning, a company uses an existing integration that already has a defined way of transferring supported information.
These solutions can be useful when many businesses have similar requirements.
For example, a connector may already support common workflows between Procore and an accounting or ERP platform.
Procore maintains an App Marketplace where construction companies can explore third-party applications and integrations across areas such as accounting, analytics, project management, and other construction workflows.
The important question is not simply whether a connector exists.
It is:
Does the connector support the way your company actually works?
An existing integration can be a strong option when the answer is yes.
Where Off-the-Shelf Connectors Work Well
Prebuilt connectors can provide a practical solution when the business process is relatively straightforward.
Standard Cost Code Structures
If your company uses a conventional and consistent cost code structure, a prebuilt connector may be able to transfer the relevant information without extensive customization.
The closer your data structure is to the connector's supported workflow, the less adjustment may be required.
Simple Accounting Setups
Companies with one primary accounting system and relatively straightforward financial workflows may find an existing connector easier to implement and manage.
If there are only a limited number of systems involved, there may be fewer mapping and synchronization requirements to address.
Small Teams
A smaller accounting or operations team may benefit from a solution that can be configured without requiring an extensive internal development effort.
A prebuilt connector can potentially reduce the amount of time the company needs to spend designing and maintaining its own integration.
Common Business Requirements
Off-the-shelf solutions are generally most attractive when the company's requirements resemble the workflows the connector was designed to support.
If the business needs basic synchronization between supported systems, purchasing an existing solution may be more efficient than building an entirely new integration.
Where Off-the-Shelf Connectors Can Become Difficult
The limitations of a prebuilt connector often become more visible as the company's workflow becomes more complex.
A connector may support a general use case but struggle when the business has requirements outside that standard model.
Custom Cost Codes
Construction companies do not always use identical cost structures.
A company may have customized cost codes, project classifications, accounting categories, or other internal structures that need to be preserved when information moves between systems.
If the connector expects a different structure, additional configuration or manual work may be required.
The question is whether the connector can accommodate the company's actual structure without forcing the business to change its process.
Multi-Entity Setups
A company operating multiple legal entities may have more complicated requirements than a single-entity business.
Different entities may use different accounting rules, project structures, or financial systems.
A standard connector may support the basic connection but not necessarily the specific entity-level rules the organization needs.
This can make implementation and ongoing administration more complicated.
Complex Approval Workflows
Construction and accounting workflows can involve multiple approvals.
For example, an invoice or financial transaction may need to pass through different people depending on the project, amount, entity, or type of transaction.
If the company's approval process does not match the connector's available workflow, the business may need additional manual steps.
Non-Supported Accounting Systems
One of the simplest limitations is also one of the most important.
If the accounting or ERP system you use is not supported by the available connector, an off-the-shelf option may not solve the problem.
In that situation, the company may need to consider another integration approach.
Unique Business Rules
Some companies have rules that are specific to their operations.
Perhaps information should move only after a particular approval.
Perhaps different project types require different mappings.
Perhaps certain records should move in one direction while others move in another.
The more unique the business rules become, the more important flexibility becomes when evaluating the integration approach.
What Does a Custom Procore Integration Get You?
A custom Procore integration is built around the specific requirements of your business.
Instead of starting with a predefined workflow and adjusting your process to fit it, the integration can be designed around the systems, data structures, and business rules you already use.
Procore itself distinguishes between Marketplace Apps and Custom Integrations. Its guidance explains that custom integrations can be developed for a specific organization's business needs, including connections to internal business systems.
That does not mean everything should be customized simply because customization is possible.
It means the integration can be designed around requirements that an off-the-shelf connector cannot adequately support.
Your Exact Data Structure
A custom integration can be designed to account for your specific project structure, cost codes, accounting fields, and other relevant data.
The mapping can be based on how your organization actually organizes information.
Your Business Rules
A custom build can incorporate rules that are specific to your workflow.
For example, the integration can be designed around defined approval conditions, entity rules, synchronization directions, or record requirements.
Your Error Handling
A custom integration can also be designed around the types of errors your organization is most likely to encounter.
Instead of treating error handling as a generic feature, the workflow can define what should happen when a record cannot be processed.
The system can potentially log the issue, identify the affected record, and notify the appropriate team.
Your Integration Scope
A custom solution does not necessarily have to synchronize everything.
The company can define which records and fields actually need to move between systems.
That can help prevent unnecessary synchronization and keep the integration focused on business-critical workflows.
No Vendor-Imposed Per-Seat Model
Depending on the commercial structure of the solution, an off-the-shelf connector may involve subscription, usage, transaction, or user-based fees.
A custom integration does not necessarily follow that same pricing model.
However, custom development still involves maintenance, hosting, monitoring, and future changes, so it should not be treated as a completely cost-free solution after launch.
The important comparison is the total cost over the expected life of the integration, not simply the initial price.
Build vs. Buy: A Simple Cost Comparison
Cost is often the deciding factor.
But comparing only the first-year price can produce the wrong conclusion.
An off-the-shelf connector may have a relatively low initial implementation cost but require recurring payments.
A custom integration may require a larger upfront investment but potentially have a different cost structure over several years.
Consider a simplified example.
Suppose an existing connector costs:
$500 per month
Over one year:
$500 × 12 = $6,000
Over three years:
$6,000 × 3 = $18,000
Now suppose a custom integration requires a one-time development investment of:
$15,000
If ongoing maintenance averages $2,000 per year, the three-year cost would be:
$15,000 + ($2,000 × 3) = $21,000
In this example, the off-the-shelf option has the lower three-year cost.
But the calculation changes if the connector costs more, if usage increases, or if the custom integration eliminates a significant amount of manual work.

The point is not that custom is always cheaper.
It is that ROI should be calculated using your actual numbers.
The Cost of Manual Work Matters Too
Integration costs should not be evaluated in isolation.
If employees spend 15 hours every week manually transferring information between systems, that work has a cost.
For example:
15 hours/week × $35/hour × 52 weeks = $27,300 per year
If an integration significantly reduces that repetitive work, the recovered employee time becomes part of the ROI calculation.
The company may not eliminate the employee's position.
Instead, those hours could be redirected toward financial analysis, project reviews, forecasting, reporting, or other work that requires human judgment.
This is why the right question is not simply:
“Which integration costs less?”
It is:
“Which option provides the better business value over time?”
How Long Does It Take to Reach ROI?
There is no universal ROI timeline for a Procore integration.
It depends on:
- Upfront implementation cost
- Recurring software fees
- Manual hours eliminated
- Employee labor cost
- Transaction volume
- Number of systems involved
- Complexity of the workflow
- Maintenance requirements
A simple calculation can provide an initial estimate.
For example, suppose a custom integration costs $15,000 and reduces manual work worth $3,000 per month.
The simple payback calculation would be:
$15,000 ÷ $3,000 = 5 months
That means the initial investment would theoretically be recovered in approximately five months.
This is only a simplified example.
Actual ROI should also consider maintenance, implementation time, changes to the workflow, and other relevant costs and benefits.
Five Questions to Decide Between Build and Buy
CFOs and operations directors can use five practical questions to narrow down the decision.
1. Is Our Workflow Standard or Highly Customized?
If your workflow closely resembles common construction accounting processes, an existing connector may be sufficient.
If your processes involve substantial customization, a custom integration may provide greater flexibility.
2. Does an Existing Connector Support Every Critical Requirement?
Do not evaluate a connector based only on whether it says it supports Procore.
Create a list of the information and workflows your company actually needs.
Then determine whether the connector supports those requirements.
A solution that handles 80% of the workflow may still leave the company with 20% of the work to manage manually.
3. How Much Manual Work Will Remain?
This is one of the most important questions.
If employees will still need to export files, correct mappings, reconcile records, or manually handle exceptions every day, the apparent simplicity of a prebuilt connector may not translate into meaningful savings.
4. What Will the Total Cost Be Over Three to Five Years?
Compare more than the purchase price.
Consider:
- Implementation
- Subscription fees
- Usage fees
- Maintenance
- Support
- Internal administration
- Future changes
Then compare that total against the expected value of the integration.
5. Who Needs to Control the Integration?
If the business needs complete control over its mapping, business rules, error handling, and future changes, a custom integration may be more appropriate.
If the company's requirements are standard and minimizing internal management is more important, an existing connector may be preferable.
When Buying Is Probably the Better Choice
An off-the-shelf connector may be a good fit when:
- Your workflow is relatively standard
- Your cost code structure is straightforward
- You use a supported accounting system
- Your organization has limited customization requirements
- Your team wants a faster path to implementation
- The recurring cost is reasonable compared with the value provided
In these circumstances, building a custom integration may add complexity without providing enough additional value.
When Building May Be the Better Choice
A custom Procore integration may be worth considering when:
- Your cost structures are highly customized
- You operate multiple entities
- Your accounting workflow has complex approval rules
- Your accounting system is not adequately supported by available connectors
- You need specific data mappings
- You require customized error handling
- Existing solutions leave significant manual work
- Your long-term integration requirements justify the investment
The objective should not be customization for its own sake.
The objective is to solve a business problem that an existing solution cannot adequately address.
A Practical Way to Evaluate Your Options
Before speaking with vendors or developers, document your current workflow.
Start with the questions:
What information currently moves between Procore and our other systems?
Who moves it?
How often is it moved?
How much time does that take?
Where do errors occur?
Which steps require manual reconciliation?
What would happen if those steps were automated?
This creates a useful baseline.
You can then compare an off-the-shelf connector and a custom integration against the same requirements.
Instead of asking which product sounds better, you can ask which option solves the actual problem.
FAQs
When does an off-the-shelf Procore connector make sense?
An off-the-shelf connector tends to work well when your cost code structure is standard, your accounting setup is simple, your team is small, and your requirements closely match the workflow the connector was built to support. The closer your actual process is to that standard workflow, the less adjustment you'll need.
When should a construction company build a custom Procore integration instead?
Consider a custom build when you have customized cost codes, operate multiple entities, run complex multi-step approval workflows, use an accounting system existing connectors don't support, or have business rules specific enough that a prebuilt solution would leave significant manual work behind.
How do you calculate ROI for a construction software integration?
Compare the total cost over three to five years, not just the first year, against the value of the manual work it eliminates. A simple payback calculation is the upfront cost divided by the monthly value of reduced manual work. For example, a $15,000 integration that saves $3,000 a month in manual work pays back in about five months.
Is a custom integration always more expensive than buying a connector?
Not necessarily, and it depends entirely on your own numbers. In a simplified example, a $500/month connector totals $18,000 over three years versus $21,000 for a custom build with $15,000 upfront and $2,000/year in maintenance, but that comparison flips once usage, connector cost, or recovered manual work changes.
What questions should CFOs ask before choosing build vs. buy?
Five matter most: is the workflow standard or highly customized, does an existing connector cover every critical requirement, how much manual work will still remain, what's the total cost over three to five years, and who needs to control the integration's mapping and error handling.
Does manual data entry between systems have a real cost?
Yes. In an example scenario, an employee spending 15 hours a week manually transferring information between systems, at $35 an hour across 52 weeks, costs the business $27,300 a year, time that could otherwise go toward analysis or reporting work.
The Right Choice Depends on Your Workflow
There is no universal winner in the build-versus-buy decision.
An off-the-shelf connector can be an efficient solution when the company's requirements are standard and the supported workflow closely matches its needs.
A custom Procore integration can provide greater control when the company has unique structures, complex processes, or requirements that existing connectors cannot adequately handle.
The best decision is the one that balances:
Fit + Cost + Flexibility + Maintenance + ROI
A lower upfront price does not automatically make a solution cheaper.
Likewise, a custom integration is not automatically a better investment.
The right approach depends on what the company needs the integration to accomplish and how much value the solution can create over time.
Final Takeaway
The build-versus-buy decision should start with the workflow, not the technology.
Off-the-shelf connectors can work well for companies with standard cost structures, supported accounting systems, straightforward processes, and limited customization requirements.
Custom integrations become more attractive when the business has unique cost codes, multiple entities, complex approval workflows, unsupported systems, or other requirements that prebuilt solutions cannot adequately handle.
The financial comparison should also include recurring fees, implementation costs, maintenance, manual labor, and the value of recovered employee time.
At Aishco Solutions, the focus is on understanding the business process first and then determining whether an existing connector or a custom integration is the more practical approach. The goal is to help businesses choose an integration strategy based on their actual requirements, expected ROI, and long-term needs.
Ultimately, the right question is not:
“Should we build or buy?”
It is:
“Which approach solves our actual integration problem at the best long-term value?”
For CFOs and operations leaders, answering that question before committing to an integration can help avoid unnecessary costs and ensure the chosen solution supports the way the business actually operates.
