Off-the-shelf catalog software rarely fits the way a real business runs its product data. If yours doesn’t, you already know the symptoms: the same product described three different ways on three channels, a launch held up because someone is still chasing images, and a stack of spreadsheets quietly doing the work the software was meant to do.
ByteGears builds catalog management software, often called product information management or PIM, around your product model and your workflow instead of asking you to bend around someone else’s. It becomes the single source of truth for product data, feeds every channel you sell on, and is built to meet UK data protection rules from the start. You own the result outright.
We’re a small London development firm, so you talk to the people writing the code, not a support queue.
Where off-the-shelf catalog software tends to fall down
Generic PIM and catalog tools are built to handle any business, which means they fit no business particularly well. A few patterns come up again and again with growing UK companies:
- Per-seat and per-channel pricing. The largest platforms charge for every editor, and often every supplier, translator or marketplace. Costs climb every time the team or the channel mix grows, regardless of how much value the tool delivers.
- Rigid approval workflows. Most tools offer a fixed two-to-four stage flow. Real approval logic is messier than that: who signs off depends on product category, price, supplier or region. Teams end up bypassing the system to get work done.
- A data model that doesn’t match your industry. Generalist PIMs ship with hundreds of attributes you don’t need and miss the ones you do, whether that’s part compatibility matrices, allergen data or GS1 identifiers.
- Scheduled feeds instead of real sync. Many platforms update channels once or a few times a day via CSV or XML. That delay is where overselling, stockouts and customer complaints come from.
- Hidden costs. Premium integrations, API overage fees, digital asset storage and extra user licences are commonly billed on top of the headline price.
- Lock-in. Once your data and workflows live inside a vendor’s platform, moving off it is expensive and disruptive, and vendors price accordingly.
Add it up and you get lost time, training overhead, surprise invoices, and the spreadsheet workarounds you were trying to escape.
What we build instead
A catalog modelled on your products
We start from how your business actually structures product data: the attributes, variants, categories and relationships that matter to you. You carry only what you use, so the system stays fast and the team isn’t wading through irrelevant fields.
Approval workflows that match your business
We encode the way sign-off really works, including conditional routing where, for example, a new product over a price threshold needs operations and legal review while a simple price change does not. No awkward workarounds, no products stuck in a queue with no escalation path.
Channel-specific data done properly
Amazon, your website, a B2B portal and a print catalog each want different attributes, formats and copy. The system holds one master record and publishes the right subset to each channel, so consistency is enforced rather than hoped for.
Real-time sync, not overnight feeds
Where it matters, we build proper API integrations so a sale on one channel updates stock everywhere in seconds, with conflict handling and retries for when a channel is briefly down.
Compliance built into the core
UK GDPR, immutable audit trails, role-based access and data retention rules are part of the design, not bolted on later. Where you work to GS1 standards, allergen rules or other sector requirements, we build those in too.
You pay once, then own it
One development cost instead of a subscription that runs forever and a per-seat bill that grows with your team. The code, the data and the documentation are yours.
What we typically build
Every catalog system we deliver covers the core, and we add whatever your sector needs on top:
- A central product database covering SKUs, descriptions, categories, pricing, status and full change history
- Variant modelling for size, colour, packaging and configuration, with clean parent and child relationships
- Custom attribute management, so you define your own fields, mark them mandatory or optional, and validate their format
- Digital asset management for images, video and documents, linked to products with version history
- Channel-specific catalogs that publish the right product data and copy to each storefront, marketplace and portal
- Bulk editing and a conditional rules engine, so updating hundreds of products at once stays consistent and safe
- Multi-stage approval workflows with conditional routing, task assignment and escalation
- Data validation and completeness scoring, so incomplete products are caught before they reach a channel
- Supplier records and, where useful, a supplier portal for self-service product data submission
- Audit trails, granular role-based access, and reporting on catalog health, channel sync status and user activity
- API and webhook integrations with ecommerce platforms, marketplaces, ERP and inventory systems
Multi-language content, supplier collaboration portals and real-time inventory sync are often best treated as a second phase once the core catalog is live and trusted.
How the build works
Discovery and planning, roughly 2 to 3 weeks
We map your current product data, your channels, your real approval logic and what needs to integrate, then audit the state of your existing data. Getting the attribute model right here is what prevents expensive rework later.
Development, roughly 8 to 12 weeks for a first release
We build in modern frameworks and ship in phases, starting with product records, digital assets, roles and your primary sales channel. You check in regularly and see working software early, so there are no surprises.
Migration and testing, roughly 2 to 3 weeks
We clean and de-duplicate your source data, map it to the new model, and run a pilot import on a subset of products before the full load. Integrations are tested against real channel data, not left until go-live.
Training and support, ongoing
We train editors, approvers and administrators separately, since each needs different things, and stay available afterwards.
A focused first release usually runs around 8 to 12 weeks. Adding multi-channel syndication, approval workflows and ERP integration typically takes the whole project to 4 to 6 months, depending on data quality and how many systems need connecting.
What it costs, and why it stacks up
Custom development is a real upfront cost. Here is what you get for it:
- No per-seat or per-channel licensing. Add editors, suppliers and marketplaces without the bill moving. Your ongoing cost is hosting and support, not headcount.
- No surprise fees. Integrations, asset storage and API usage are part of the system, not metered add-ons.
- No lock-in. You own the code and the data, and you can evolve the system on your own schedule rather than waiting on a vendor roadmap.
- It can be treated as capital expenditure rather than a recurring operating cost.
For a team with several editors, multiple suppliers and a growing channel mix, ownership cost tends to even out against SaaS within roughly two to three years, and the gap keeps widening after that. The actual price depends on your catalog size, channels and integrations. Get in touch for a free consultation and a realistic estimate.
Industries we build for
Custom catalog systems earn their place where the product data or the workflow has real complexity:
- Retail and ecommerce, keeping sizing, colour and descriptions consistent across website, Amazon and other marketplaces
- Wholesale and B2B distribution, ingesting messy supplier catalogs into one normalised, validated source for a trade portal
- Manufacturing, for complex configurations, technical specifications and documentation
- Food and beverage, for allergen declarations, nutritional data, ingredient traceability and GS1 support
- Health and pharmacy supplies, for batch tracking, certifications, regulatory audit trails and identifier standards
- Automotive parts, for part hierarchies, vehicle compatibility matrices and OEM cross-references
- Construction materials, for organising products by specification and project requirement
- Fashion and apparel, for variant-heavy ranges with size, colour and stock spread across channels
Because the system is built for you, it handles the sector-specific quirks a generic tool either ignores or buries under fields you will never use.
Common Questions About Custom Catalog Management Software
Is this the same as PIM software?
In practice, yes. What people call catalog management is usually product information management: one place to create, enrich, validate and publish product data across your website, marketplaces, B2B portal and print. We build it around your product model rather than a generic PIM template, so you only carry the attributes and workflows your business actually uses.
How does custom development cost compare to SaaS or PIM platforms?
SaaS PIM platforms usually charge per editor seat or per channel, so the bill grows every time you add a contributor, a supplier or a marketplace. A bespoke build is a larger upfront cost, after which you pay for hosting and support rather than licences. For teams with several editors, suppliers and channels, ownership cost tends to even out over roughly two to three years, and the gap widens after that. We give you a clear estimate before you commit.
What's the typical development timeline?
A focused first release covering product records, digital assets, roles and a single sales channel usually takes around 8 to 12 weeks. Adding multi-channel syndication, approval workflows and ERP or inventory integration extends that to roughly 4 to 6 months. We ship in phases so you are using the core system while later modules are still being built.
Can you integrate with our ecommerce platform, marketplaces and ERP?
Yes. We commonly connect to Shopify, WooCommerce, Magento and BigCommerce, to marketplaces such as Amazon and eBay, and to ERP and inventory systems including SAP, Oracle, NetSuite and Microsoft Dynamics. Where a legacy system has no modern API, we build a custom integration or import routine instead of forcing you onto expensive middleware.
Can it sync inventory in real time instead of using scheduled feeds?
Yes. Many SaaS platforms push data to channels on a daily or hourly feed, which is how overselling and stockouts happen. We can build proper API integrations so a sale on one channel updates stock everywhere within seconds, with conflict handling and retry logic for when a channel is briefly unavailable.
How do you handle data migration from spreadsheets or an old system?
Migration is usually the hardest part of a catalog project, because source data tends to be spread across spreadsheets with duplicates, typos and missing fields. We audit your data first, agree how attributes map, clean and de-duplicate it, and run a pilot import on a subset of products before the full load. That avoids importing old problems into a new system.
What about data security, audit trails and UK GDPR?
We build to UK GDPR and the Data Protection Act 2018, with UK or EU hosting, encryption in transit and at rest, and granular role-based access. Every product change is logged with the user, timestamp and before-and-after values, so you have an audit trail for regulatory inspections, and we can support retention rules and right-to-be-forgotten where customer data is involved.
Do you provide training and ongoing support?
Yes. We train product editors, workflow approvers and administrators separately, since each needs different things, and provide written documentation. Every project includes 12 months of support. After that you can take a maintenance plan with us or run the system in-house, since you own the code and the documentation.
