“How much does builders merchant software cost?” is one of the hardest questions to get a straight answer to, vendors quote per branch, per user, per module, and rarely publish a price. Here is an honest, jargon free guide to what you should expect to pay, and where the money really goes.
Why there is no sticker price
Merchant ERP systems like Kerridge K8, Intact iQ and Ibcos Gold are sold as tailored implementations, not off the shelf licences. The final figure depends on how many branches and users you have, which modules you take (stock, point of sale, accounts, purchasing, delivery, ecommerce), whether you host it yourself or in the cloud, and, the big one, how much data migration, configuration and training the rollout needs. Two merchants of similar size can pay very different amounts.
The realistic cost ranges
As a rough guide for the UK builders merchant market, budget for two things: an up front implementation cost and an ongoing monthly or annual cost. The figures below are typical market ranges to help you plan, always get a written quote for your own situation.
| Merchant size | Typical up front (setup, migration, training) | Typical ongoing (licences + support) |
|---|---|---|
| Single branch, a few users | Low thousands to ~£15k | Hundreds per month |
| Small multi branch (2, 5 sites) | ~£15k, £50k | Four figures per month |
| Larger group (6+ sites) | £50k, six figures | Four to five figures per month |
On top of the software itself, factor in the hidden costs that catch merchants out: the staff time lost during migration, the temporary dip in productivity while everyone learns the new system, integrations with your existing tools, and the cost of any hardware (scanners, tills, servers). These “soft” costs are frequently as large as the licence fee itself.
Replace, or add to what you have?
Before you commit to a six figure replacement, it is worth asking whether you actually need a new ERP, or whether the system you already run is fine and the real problem is the manual work around it. A full replacement is an 18 month project with real risk. For many merchants, the smarter and far cheaper move is to keep the ERP that works and make it work harder.

How to compare quotes fairly
When you do go out to tender, insist that every quote breaks out the same line items so you can compare like with like: the software licences, the implementation and data migration fee, training days, ongoing support tier, and the cost of each optional module. Ask specifically what happens to the price in year two and three, and what it costs to add a branch or a user. And read our builders merchant ERP comparison before you shortlist.

Frequently asked questions
How much does builders merchant software cost per month?
It varies widely by size. A single branch merchant might pay hundreds of pounds a month in licences and support, while a multi branch group can pay four or five figures a month. Up front implementation and migration is usually a separate, larger one off cost.
Why won\u2019t vendors publish a price?
Merchant ERP is sold as a tailored implementation, so the price depends on your branches, users, modules, hosting and how much migration and training you need. Vendors quote per situation rather than a fixed list price.
What are the hidden costs of new merchant software?
Beyond the licence fee, budget for data migration, staff training, a temporary productivity dip during rollout, integrations with your other tools, and any new hardware. These soft costs are often as large as the software itself.
Is it cheaper to add AI than replace my ERP?
Usually, yes. An AI layer like OptiFlow sits on top of your existing system and automates the manual work without a migration project, so you avoid the largest costs of replacement \u2014 and you are live in weeks rather than many months.
