Most product data problems start the same way: a spreadsheet that worked fine at 200 SKUs, a second sales channel, then a third, and suddenly nobody is sure which description, price or image is the correct one. A Product Information Management system is meant to fix that by holding one authoritative version of every product and pushing it out consistently to your website, marketplaces, retail partners and print. The trouble is that getting there shouldn’t mean fighting your software or signing up to an open-ended subscription that grows every time you add a person or a SKU.
We build custom Product Information Management Systems for UK businesses. Off-the-shelf PIMs ask you to fit your catalogue into their idea of how a product should look. Ours are shaped around your actual attributes, your suppliers, your approval rules and the channels you sell through.
We’re a London consultancy focused on business automation, and when we deliver a system, you own it. No per-user licence, no per-SKU overage charges, no feature gates. We take on a small number of clients at a time so each project actually gets our attention.
To be straight about it: if your catalogue is small and standard and you sell through one or two mainstream channels, a SaaS PIM will probably serve you well, and we’ll say so. Custom work earns its place when the off-the-shelf options would have you paying for a generic platform and then patching around it.
Where off-the-shelf PIMs fall short
The PIM market splits roughly in two. At the affordable end, tools like Plytix and Quable are genuinely good for straightforward catalogues. At the enterprise end, Akeneo, Inriver and Syndigo carry serious capability but also serious cost and complexity. For a lot of mid-market UK businesses, neither end fits cleanly, and the gap is where the friction shows up:
- Per-user and per-SKU pricing that compounds. Enterprise PIM licences are often charged per seat or per module, and a usage-based plan can add overage charges as your catalogue grows. A team of 50 might pay for 50 licences when only 10 use the system daily. Stretched over three to five years, that quietly overtakes what a custom build would have cost.
- Implementation costs hidden behind the headline price. The licence is rarely the whole bill. Data migration, integration development, training and professional services routinely add tens of thousands of pounds, and enterprise rollouts can run six to twelve months before anyone gets value.
- Rigid approval workflows. Standard workflow engines handle “draft, approved, published” well enough. They struggle with conditional logic such as “extra sign-off only for a new supplier” or “escalate if the price change is over 10%”. Bespoke business rules often mean custom code or paid professional services.
- Half-finished integrations. Vendors offer connectors for the popular platforms. If your ERP is older, your warehouse system is bespoke, or your accounting tool isn’t on the list, you’re back to manual syncing and the inventory drift that comes with it.
- Your catalogue doesn’t map cleanly. Specific attributes, deep hierarchies, regional variants and channel-specific overrides often don’t fit the platform’s data model without compromise.
- Vendor lock-in. Proprietary data formats, multi-year contracts and termination fees make switching expensive once you’re in.
What that usually adds up to is a pile of spreadsheets sitting alongside the PIM you paid for, manual reconciliation, and product errors reaching customers because the data was approved in one place and edited in another. You end up paying for features you don’t use and patching around the ones you actually need.
What we do differently
A few things shape how we approach this kind of project.
Built around your process
Before any code gets written, we sit down with your team and map how product data actually moves through the business: who creates it, who enriches it, who signs it off, and where it goes. The finished system reflects that, which cuts training time and stops people quietly going back to spreadsheets.
Approval rules that match reality
Your sign-off process is a feature, not an afterthought. We build the conditional routing, escalations and role-based approvals your business actually runs on, including the awkward rules that standard platforms can’t handle without paid customisation.
One-time investment
You pay to build it, then you own it. No recurring per-user licence, no per-SKU overage charges, no forced upgrades on someone else’s schedule.
Integrations that actually work
We build connectors for the tools you already run: Shopify, Magento, WooCommerce or BigCommerce; marketplaces like Amazon and eBay; ERP and accounting systems such as SAP, NetSuite or Xero. We handle attribute mapping, channel-specific overrides and proper error handling so a broken sync doesn’t corrupt your catalogue. Where a legacy system has no modern API, we work with CSV, XML or EDI exchange instead.
UK compliance baked in
UK GDPR, role-based access, audit trails and UK hosting are part of the design from the start. Where your sector demands it, so are the specifics: allergen data for food, MHRA documentation for healthcare, UKCA and CE records for manufactured goods.
Room to grow
We start with the features you need now and add to them as your range expands or you open new sales channels. The architecture is API-first, so a new marketplace or a Phase 2 module is an addition, not a rebuild.
Support from the people who built it
Our team is in London. Support happens in your timezone, in plain English, and you talk to the developers who know your system, not an offshore queue working from a generic playbook.
Core features in every PIM we build
The specifics differ by sector, but most of our PIM projects cover the same ground:
- A centralised product record that acts as the single source of truth: SKUs, attributes, descriptions, pricing, status and effective date ranges, with channel-specific and language-specific overrides where you need them.
- A flexible data model for custom attributes, deep taxonomies and product hierarchies that match your real catalogue, not a generic template, with validation rules so mandatory fields can’t be skipped.
- Variant management for size, colour, material, capacity and fit, with pricing, imagery and stock tracked per variant.
- Multi-channel syndication, so the same approved product data publishes to your website, marketplaces and print without anyone copying and pasting, and without different channels drifting apart.
- Approval workflows with multi-level sign-off, conditional routing and escalation for overdue items, built around your actual process.
- Bulk editing and import, so you can update hundreds of records at once and bring legacy data in from spreadsheets, with completeness scoring so nothing ships half-finished.
- Digital asset management for images, video, technical drawings and documentation, properly linked to the right products and delivered over a CDN.
- A supplier portal, so vendors can submit and update their own product data against your templates while you keep oversight and approval.
- Reporting and data-quality dashboards covering completeness, publication status by channel, approval bottlenecks and audit history, with the option to tie product data to the business questions that matter to your P&L.
- Role-based permissions and audit trails, with fine-grained control over who can see or edit which attributes, plus versioning and change history for compliance.
- An API-first architecture designed from day one to talk to the systems you already run and the ones you might add later.
How a project usually runs
Most projects move through four phases. The timings below are typical for a focused first build, not promises.
Discovery, planning and data audit (2 to 4 weeks)
Workshops and system audits to document how you work now, where it hurts, and what needs to integrate. Crucially, this is where we assess your existing product data. Legacy data is nearly always messier than expected, with duplicate SKUs, inconsistent naming and missing images, and that cleanup is the single most common reason PIM projects slip. We’d rather find it here. It’s also where we push back if something in the brief doesn’t add up, or if a SaaS tool would genuinely serve you better.
Custom development (8 to 16 weeks)
Our UK developers build the solution on modern frameworks. We start with a deliberately focused first version: core product data, your primary sales channel, basic asset management, approval workflows and reporting. You see progress regularly rather than getting a black box, and you get to try things mid-flight. Over-engineering the first release is a known way to delay launch, so we keep it lean on purpose.
Migration, testing and deployment (3 to 5 weeks)
We migrate your product data, run it in parallel with the old system, and put it through QA and user acceptance testing before cutover. We’d rather find the problems here than after launch, so this phase is unglamorous by design.
Training, support and Phase 2 (ongoing)
Role-specific training for administrators, content managers, approvers and eCommerce staff, written documentation, and UK-based support after launch. Once the first version is stable, Phase 2 work typically adds extra marketplaces, ERP integration, a native mobile interface for field or store teams, or custom analytics. Most clients keep us on a light retainer for this.
What it costs (and what you own)
Custom development is a larger upfront commitment than a SaaS sign-up. The comparison that matters is total cost over three to five years, and there a custom build often looks very different:
- No recurring per-user fees that scale with your team, and no per-SKU overage charges as your catalogue grows.
- No connector add-on fees. Integrations are built in, not licensed separately.
- Implementation isn’t a hidden line item. With SaaS PIM, migration, integration and professional services frequently add tens of thousands of pounds on top of the licence. With a custom build that work is the build.
- A system you own. Your data is portable, your code is documented, and there are no termination fees or proprietary formats holding you in.
- Workflows shaped around your business, which cuts the manual reconciliation and the small errors that reach customers.
Actual numbers depend on scope, particularly the size of your catalogue, the number of channels and how much integration and compliance work is involved. We’d rather scope properly than quote a number on a web page. The free consultation gets you a transparent estimate against your real requirements.
When SaaS is enough, and when it isn’t
We’d rather you spent your money well, so here’s the honest version.
A SaaS PIM is usually the right call when your catalogue is under a few thousand SKUs with simple variants, you sell through one to three mainstream channels, your attributes are standard, your approval process is short, and the available connectors cover your stack. In that situation a tool like Plytix gets you running in weeks at predictable cost.
A custom build starts to make sense when one or more of these is true:
- Your catalogue is large or your hierarchies and variants are intricate.
- Your approval process has conditional logic tied to business rules, not a simple linear sign-off.
- You need to integrate with legacy ERP, warehouse or internal systems that standard connectors don’t cover.
- Compliance is central to your product data, and you need it enforced rather than bolted on.
- You need custom reporting, or a proper mobile interface for field and store teams.
- Per-user or per-SKU pricing is becoming a real cost, or vendor lock-in is a genuine concern.
If you’re somewhere in between, the consultation is the place to work it out. We’ve talked clients out of a custom build before now.
Where this kind of PIM works well
Custom PIM tends to earn its keep in:
- Fashion and apparel, juggling thousands of variants across size runs, colours and materials, with fast seasonal launches and localised content for international stores and marketplaces.
- Food and drink manufacturing, where allergen, nutritional and ingredient data has to stay accurate and auditable across multiple production sites, with Natasha’s Law and FSA requirements enforced at the point of data entry.
- B2B machinery and manufacturing, where detailed technical specs, certifications and multi-language documentation feed distributor portals, and version control on safety documentation matters.
- Pharmacy and healthcare retail, with MHRA-compliant product information, regulatory documentation and pricing that varies across NHS, private and store-level contexts.
- Automotive aftermarket, where complex hierarchies of brand, model, year and engine, plus fitment and compatibility data, keep the wrong part out of the wrong vehicle across many channels.
- Wholesale and distribution, with catalogue management aimed at B2B buyers: pricing tiers by customer, minimum order quantities, lead times and supplier data alongside the product record.
- Luxury and high-end retail, where rich storytelling, premium photography and consistent brand voice have to hold up across boutiques, department stores and online.
- eCommerce marketplaces and aggregators, standardising product data from hundreds of vendors, enforcing quality and compliance, and onboarding sellers against templates.
The common thread is product data that won’t sit quietly in a generic template, and a business that would otherwise be paying a platform to do roughly the job and then doing the rest by hand.
Common Questions About Custom Product Information Management Systems
When should we choose a custom PIM over an off-the-shelf one like Akeneo or Plytix?
If your catalogue is modest, your attributes are standard, and you sell through one or two mainstream channels, a SaaS PIM such as Plytix is often the sensible choice and we'll tell you so. A custom build earns its place when you have complex variants and hierarchies, multi-step approval rules tied to business logic, integrations with legacy ERP or warehouse systems that standard connectors don't cover, or compliance obligations the platform doesn't handle natively. The honest test is whether you'd be paying for a generic platform and then fighting it.
How does the cost compare to a SaaS PIM subscription?
A custom PIM is a larger upfront investment than a SaaS sign-up, but you avoid per-user licences, per-SKU overage charges, and connector add-on fees that compound year on year. Enterprise PIM contracts also carry significant implementation and professional-services costs that rarely show up in the headline price. With a custom build you pay to build it, then you own it. We scope and quote against your real requirements rather than quoting a number here.
What's the typical development timeline?
A focused MVP, covering core product data, one primary channel and basic workflows, usually takes three to four months. A mid-market build with several channels and ERP integration is more like six to nine months. Larger enterprise projects with heavy syndication and compliance work can run longer. Data migration from messy legacy systems is the phase most likely to stretch, so we assess it early.
Can you integrate with our existing systems?
Yes. PIM rarely sits in isolation, so we build connectors for the eCommerce platforms, marketplaces, ERP and accounting tools you already run, typically over REST APIs, webhooks or scheduled imports. Where a legacy system has no modern API, we work with CSV, XML or EDI exchange instead. We handle the awkward parts: attribute mapping, channel-specific overrides, and error handling so a failed sync doesn't corrupt your data.
How do you handle product data migration?
We start with a data audit before committing to a timeline, because legacy product data is almost always messier than expected: duplicate SKUs, inconsistent naming, missing images and stale attributes. We extract, clean, deduplicate and validate your existing data, then run it in parallel with the old system before cutover. Underestimating this work is the most common reason PIM projects slip, so we plan for it openly.
What about UK compliance and data security?
UK GDPR, role-based access, encrypted storage, full audit trails and UK hosting are part of the design from the start. Where your sector demands it, we build in the specifics: allergen and nutritional data with Natasha's Law in mind for food and drink, MHRA documentation and change control for healthcare, and UKCA or CE certification records for manufactured goods. Audit trails capture who changed what, when and why, with versioning for the retention periods regulators expect.
Do you provide training and support after launch?
Yes. We provide role-specific training for administrators, content managers, approvers and eCommerce staff, plus written documentation. After go-live you get UK-based support from the people who built the system, and most clients keep us on a light retainer for tweaks, new channels and feature work as the business grows.
