What is bespoke software? Eight examples

What the word covers, the three different things sold under it, and eight systems that show what it looks like in a working business.

The short answer

Bespoke software is software written for one business, around the way that business works, and owned by it. Custom software means the same thing. The alternative is a product sold to thousands of firms at once, such as Xero or Salesforce.

In a business of ten to two hundred people, bespoke software rarely replaces those products. It usually sits between them and does the one job none of them does, which is why the examples below look so ordinary.

The word comes from tailoring. To bespeak something was to order it in advance, so a bespoke suit was made for one customer who had ordered it. In 2008 the Advertising Standards Authority looked at a firm advertising a "bespoke suit" for £495 that was cut and sewn by machine in Germany. The Telegraph reported it as Savile Row’s tailors losing their fight over the word. The ASA decided most people would not expect a bespoke suit to be entirely hand made, and let the firm keep using it.

Software sellers stretch it in the same way. A "bespoke CRM" can mean a system written from nothing, or a standard product with your logo and a few extra fields. Both are sold under the same word and they are different purchases.

Three different things sold as bespoke

What you are offered	What it is	Who owns what	What changing it later involves
A configured product	A product such as HubSpot, monday.com or Sage, set up with your fields, stages and reports.	The vendor owns the product. You rent it and own your data.	Whatever the product allows. If it does not allow it, nobody can make it.
A product with bespoke pieces	The product, plus something written for you: a connection to your accounts package, a screen for one awkward job.	The vendor owns the product. The pieces written for you can be yours, if the contract says so.	The product part changes when the vendor decides. The pieces change when you pay for it.
A bespoke system	Software written for your business, usually connected to the products you keep.	Yours, if the contract assigns it to you. Your data lives in it.	Anything, at the price of the work. Nobody else is asking for changes or paying for them.

All three are reasonable buys. The mistake is paying the price of the third and receiving the first.

Ask a supplier which row they are quoting for. A straight answer takes one sentence. If the answer is a paragraph about flexibility, it is usually the first row.

Eight examples of bespoke software

These are systems we built. Each one links to the full write-up, with the screens.

Business	What was going wrong	What was built
An independent grocery chain	Four shops, no margin figure for any single product, and stock losses nobody could explain.	Stock counts on a phone, margin per product line, and losses flagged as they happen.
A regional food wholesaler	Deliveries run through eleven WhatsApp groups and a magnetic map on the office wall.	One screen the owner opens on his phone, fed by the trackers already in the vans, and a driver app that keeps working without signal.
A drinks manufacturer	Three people spent a fortnight every cycle assembling regulatory paperwork by hand.	The same paperwork produced on a schedule from the records the business already keeps, with a person signing it off.
A construction contractor	Purchasing ran on paper forms and handwritten sign-offs.	Requests raised on site, approved from a phone, with the existing spending policy built in unchanged.
An accountancy practice	Three offices kept three versions of the same deadline spreadsheet, and client records were chased from personal inboxes.	A portal for clients, filing dates pulled from Companies House and HMRC, and one board of deadlines across the three offices.
A building services contractor	Engineers arrived at a site knowing nothing about previous visits. The history was in a filing cabinet forty miles away.	Each boiler and plant item’s history and certificates on the engineer’s phone, including in basements with no signal.
A skincare brand	Shopify, the warehouse and Xero each correct on their own and never in agreement. One person spent every Monday finding out why.	One view of every order across the three systems, with each stuck order shown next to the reason it is stuck.
A twelve-site hospitality group	Each manager built a weekly return and emailed it on Tuesday, so head office compared the sites three weeks late.	All twelve sites’ figures in one place by 6am on Monday.

What the eight have in common

None of them replaced the accounts package. Xero, Sage, Shopify and the vans’ trackers all stayed. The bespoke part read from them, wrote to some of them, and did the job that had been living in a spreadsheet, a group chat, a filing cabinet or one person’s memory.

Often the person carrying that job was the owner. At the wholesaler, much of what kept the routes running was knowing which kitchen wants its delivery before the chef arrives and which gate to use, and only the owner knew it. Writing that down took two afternoons with him before anything was built.

Three of them put the work on a phone: stock counts, deliveries and engineers’ job sheets. None of the three is in an app store, which saves more than it sounds, as what a business app costs explains.

What you get, and what it costs you

You get	You give up
It follows your process, including the exceptions a product would turn into a workaround.	Nobody else pays for its improvements. With a product, thousands of customers fund every new feature. With bespoke, you fund each one.
Nobody can raise your price per user, remove a feature you rely on or be bought by a competitor.	Nobody else finds its faults first. A product’s faults are reported by thousands of users before most of them reach you.
Your data sits where you can see it, in a shape you chose.	Somebody has to look after it every month, and that costs money for as long as you use it.
You can take it to another supplier.	Only if the contract says it is yours. Without that, you may have paid for something you are only allowed to use.

When bespoke is the wrong answer

The process is the same in every business. Payroll, VAT returns and bookkeeping have good products, and HMRC publishes a list of software recognised for Making Tax Digital. Writing your own means paying to rebuild what you could rent for a monthly fee.
The budget is under about £10,000. Below that, the cost of specifying, testing and documenting the work outweighs what you get, and a product with a workaround is the better deal.
The business is about to change shape. If you are merging, splitting or changing what you sell next year, build after the change, not before it.
A product does nine tenths of it. Use the product, and pay for a small connection or report to cover the last tenth. The build or buy guide has a five-question test for this.

What it costs and how long it takes

Published UK ranges put a focused system at roughly £15,000 to £35,000 and a system several people run on at £35,000 to £95,000. The cost guide breaks that down, and our own prices are published. Of the eight above, the engineers’ app took ten weeks and the wholesaler’s system fourteen.

Common questions

Is bespoke software the same as custom software?

Yes. Bespoke is the more British word and the one people in the UK search for when they want a definition. Both mean software written for one organisation rather than a product sold to many.

What is an example of bespoke software?

A system that shows a contractor’s engineers each boiler’s full history on their phone in a basement with no signal. Or one that gathers twelve restaurants’ weekly figures by 6am every Monday. Both connect to products the business already used and do a job none of those products did. There are eight worked examples above.

What is the difference between bespoke and off-the-shelf software?

Off-the-shelf software is one product sold to many customers, who rent it and share its improvements. Bespoke software is written for one customer, who owns it and pays for every change. Most businesses use both. You may also see off-the-shelf software called COTS.

Who owns bespoke software?

In the UK, whoever wrote it, unless they were your employee or have assigned the copyright to you in a signed document. Without that document you may only have a right to use it. A properly written contract assigns it to you on payment. Check for that clause before you sign anything.

Why is bespoke software expensive?

Because one customer pays for all of it. A product spreads the cost of building, testing and improving across thousands of customers. That is also why bespoke only makes sense for the part of the business where no product fits.

How long does bespoke software take to build?

A focused system for one process usually takes eight to sixteen weeks. Larger systems used across a business take three to six months. Of the examples above, the engineers’ app took ten weeks and the delivery system fourteen.
