Bespoke Software Development Cost UK: Is £20k+ Worth It?
Many businesses in the UK will look at spending £20,000+ on developing their own software as too expensive, especially when an existing product offers similar features for a small monthly fee. However, once you factor in staff time and maintenance costs, bespoke development can save you money.
So, is bespoke software development worth £20k+?
The answer depends on your business, the problems you’re trying to solve, and the long-term value a tailored solution could deliver. In this guide, we’ll explore when bespoke software makes financial sense, how to compare it with SaaS subscriptions, and what to consider before investing in a custom-built solution.
£20k Is Not the Decision: The Business Problem Is
The £20,000 development project might seem like a lot of money when you consider that it costs £100 a month to subscribe to a SaaS service. That’s not the right comparison, however. Assume that a company is using multiple platforms to spend £1,500 per month on a critical workflow. Not counting staff time, integrations and manual work, that’s £18,000 per year!
That’s £54,000 in subscriptions over three years.
Now introduce the employee who exports data, does data quality checks in spreadsheets, copies information between systems and resolves errors during integration.
Suddenly, a bespoke software development project deserves a closer look.
This is not to say that the bespoke system will necessarily be less expensive. It refers to the business making a total cost evaluation and making a business value evaluation, not just evaluating the bill of the development compared to one SaaS price.
When Off-the-Shelf Software Starts Becoming Expensive
If your process matches how the software works, SaaS is a great option.
Issues come about when the business process is different.
You might have to:
- Transfer information from one system to another.
- Pay extra money for extra software to connect to two platforms.
- Maintain spreadsheets alongside your other systems.
- Upgrade to a higher-priced tier for one feature you need.
- Develop manual approval procedures.
- Have staff fill out the same data multiple times.
- Develop solutions that overcome restrictions on the platform.
None of these costs will necessarily be listed as a line item on the software bill.
Yet someone is paying for them.
Typically, this person is your operations team.
The First Test: Is the Workflow Important Enough?
Not every awkward process needs bespoke development.
It is likely that building a new system is not a worthwhile investment when the employee needs to spend 20 minutes per month to deal with a software limitation.
This changes if 10 people work around the same restriction for several hours each week.
Our first question would be:
What is the business’s dependency on this workflow?
A bespoke system is more appropriate if the process is customer experience or day-to-day operations.
Think about:
- Quotation management
- Order processing
- Stock and Inventory Management
- Customer portals
- Booking systems
- Internal approval systems
- Reporting and data consolidation
- Bespoke ecommerce functionality
- Industry-specific operational processes
The more often the process occurs, the greater the cost of a bad workflow.
A Real Example: A Quotation System for Owen Brothers Catering
RVS Quotation Builder is just one example of how we can help a business by creating software to suit their needs. Owen Brothers Catering have been supplying office breakfast’s, lunch’s and events around London for many years. So we created a quotation builder for them.
Normally when buying something from a website you can just click buy but when someone wants catering they usually want it tailored to there needs. Whether its for a meeting at their office or if they want to hire us for there wedding. There will always be different products and quantities. So a standard web store would not have worked for this business.
We built a custom quote system to suit the Owen brothers catering.
Our quotation builder allows the user to:
- Pick a customer or create a new one.
- Select products and services.
- Change quantities and prices.
- Create a quotation for that customer.
- Email a quotation to that customer.
- Allow the user to save quotes so they can send them out quicker.
As you can see by creating software to fit a business we can save time by having less admin to complete and help them look more professional.
When £20k+ Starts Making Financial Sense
There are a number of circumstances in which a bespoke software development project is the right call.
1. You’re Paying for Several Tools to Run One Process
Many businesses end up running one process across several tools:
- One SaaS tool manages customer data
- Another handles orders
- A third takes care of automation
- A fourth handles reporting
- And Excel fills the gaps in between
That can be the right approach if each tool solves a different problem. But if they all support one internal workflow, it may be worth consolidating them into a single bespoke system.
2. Your Team Is Doing Repetitive Manual Work
There should be software to eliminate repetitive administration when possible.
If staff are routinely recording customers details, looking at records, transferring order information or creating the same documents, then work out the cost.
Manual work, for instance, means that 15 hours a week can be used at an internal rate of £25 per hour (fully loaded), which is around £19,500 per year.
Not to mention any errors or delays.
A £20k development project is very different to an identifiable annual operating cost.
3. Your Integrations Are Becoming the Product
Integrations are not an evil thing.
The issue is when your business process relies on a series of expanding them.
- Information is transmitted from System A to System B.
- System B sends something to System C.
- Then a spreadsheet fills a void.
- The result is checked by an employee.
Someone has to update the process if one system alters its API or pricing.
At this stage, you may be paying for connections between systems rather than improving the process.
4. The Process Is Your Competitive Edge
This is likely the most compelling one to argue for bespoke development.
If it’s a process that your competitors could purchase from the same SaaS provider tomorrow, it might not make much sense to bespokeise.
However, if your process is integral to your bespokeer acquisition, or is helping you to run more efficiently, owning the software that drives your process may be more of an advantage for you.
A manufacturer that has a specialised quoting system is one example.
Another is a distributor that has an extremely niche ordering process.
Another may be a business that has a complicated service model that it is building around a bespokeer portal.
You’re not just buying software.
You’re building the digital foundation around what your business does best.
Don’t Forget the Cost After Launch
Custom software solutions don’t just stop once they are developed and up and running. You will have to think about where you are going to host your application and any ongoing costs you may incur such as maintenance and support, bug fixes and new features you may want to implement down the line.
Here’s an illustrative comparison of the costs to consider over five years:
| Cost factor | Bespoke software | SaaS solutions |
| Initial cost | £25,000 development | £0–£2,000 setup |
| Ongoing costs | £500/month for maintenance and support | Monthly or annual subscriptions |
| Five-year ongoing cost | £30,000 | Depends on subscription fees |
| Integrations and add-ons | Depends on requirements | May incur additional fees |
| Five-year total | £55,000 | Depends on the SaaS stack |
Figures are illustrative. Additional hosting, future development, SaaS setup fees, and other costs may apply.
Compare your costs over 5 years of custom-built software vs what all those SaaS products would add up to plus integration and time.
You may find that custom built is more cost effective in the long run. It’s just finding what works best for you and your business.
So, Is Bespoke Software Worth £20k+?
Bespoke software is worth £20,000+ when the cost of keeping your current setup is higher than the cost of building something better. The development price alone shouldn’t be the deciding factor.
If your existing software works well, there’s no reason to replace it. But it’s time to compare the costs seriously if:
- You spend hours every week doing admin or copying data from one system to another
- Your using multiple subscription services to complete one task
- The process gives your business a competitive edge that off-the-shelf tools can’t support

Frequently Asked Questions
When a vital workflow is contributing to high, recurring expenses, and manual tasks or limitations are creating problems that would not be easily addressed by off-the-shelf software, it’s time for a bespoke solution for the small business.
Yes, a bespoke software project can cost £20,000, and, when it is well defined with the initial release dedicated to one specific workflow, it can be sufficient.
Bespoke software isn’t automatically better than SaaS. Bespoke software tends to make more sense when the business process is specialised, important, or costly to be handled by several disparate pieces of software; SaaS is typically more useful when an existing SaaS application fits into the business process.
