ShopFlow handles the things you actually need, without the rest of the bill.

What our clients say

20 clients. A few of their words.

Working with Dev Partners to redesign and modernise our WMS system: the whole process has been thoroughly professional from the outset and a delight to work with. Cannot recommend enough.

Great agency. Have used Dev Partners for several years and they have built 20+ sites for us, in addition to taking on our legacy websites, upgrading and maintaining. Easy to work with and some great practical ideas to improve our digital offerings.

Jones Hire have been working with Dev Partners on several projects, which have been very successful. They linked our catering database to a new improved website so clients can easily place and update orders, created a custom warehouse picking app to fulfil all our challenging requirements, and are currently developing a custom transport app to streamline our loading and delivery process.

We have been trying to reinvent our website for over 5 years, trying to make it convert and failing each time. Spoke to Rob at Dev Partners, the team helped create our new site and the improvement was instant.

We have been working with Rob and the team for about 10 years now. Dev Partners helped us build a completely bespoke CRM from scratch which manages our daily business and is always well maintained. We have been able to use the system and roll it out in our new franchise branches.

We collaborated with Dev Partners on the front end of a fairly complex telemarketing platform. Rob and Jason took the time to properly understand the moving parts, asked the right questions, and delivered a clean, intuitive interface that's made the system far easier for our team to use.

I have been working with the team at Dev Partners for the last 3 years and we have always been impressed with the speed in which they act on things for us, along with the honest open communication. The team are a valuable and vital part of our supply chain.

We've had a program for our business in the electronic security sector that Dev Partners developed and keep up to date. They've never let us down, always there when needed. Thanks Rob and the team.

Dev Partners have been working with us for just over 2 years. They have significantly upgraded and redesigned our existing web platforms, and always deliver a first class service.

Dev Partners helped us build an event website. The team were very knowledgeable, easy to work with and quick to deliver a high quality product.

Working with Dev Partners has been an exceptional experience. Their team is highly skilled, professional, and committed to delivering results. What truly sets them apart is their communication and transparency; we always felt informed, supported, and confident.

We've worked with Dev Partners a few times to support us on bespoke web build tasks. They're very easy to work with, approachable, and explain the detail in a way that's understandable. A great partner for technical issues at sensible prices.

Excellent customer service backed up with solid experience. As a media business we have had five websites built by Dev Partners. I would certainly recommend them.

Found Dev Partners and they were great, nothing too much trouble. They managed to help us with integrating our old existing system with Shopify.

I've worked with Rob and his team off and on for many years and have always found them to be professional, knowledgeable, and best of all, they listen to their clients and deliver what is required.

We have worked with Dev Partners for 7 years and can highly recommend them for their expertise and excellent customer service.

ShopFlow frequently asked questions

The questions we get most often from retailers considering ShopFlow.

ShopFlow is an inventory and order management platform built specifically for Shopify retailers. Unlike a full ERP system, it focuses on the operations that matter to a Shopify retailer: inventory management, order processing, returns, pick and pack, fulfilment, and courier integration. It does not include global tax modules, multi-entity financial consolidation, HR systems, or the dozens of other modules that push ERP licensing costs into the tens of thousands per year.

The practical difference is cost and simplicity. A full ERP implementation typically costs £50,000 to £150,000 upfront and £20,000 to £50,000 annually in licences. ShopFlow runs on a fixed monthly licence, deploys in 6 to 12 weeks, and covers everything most Shopify retailers actually use. Retailers making the switch typically save £20,000 to £50,000 per year.

ShopFlow is designed for Shopify retailers turning over between £2 million and £50 million or more, shipping hundreds to thousands of units per day. It is proven in production with UK fashion retailers processing thousands of orders daily across multiple warehouses.

It is not designed for very small retailers who would be adequately served by Shopify's built-in tools. If you are processing fewer than a few hundred orders a day and running a single warehouse, Shopify's native order management may be sufficient and ShopFlow would be disproportionate. The right starting point is a conversation about your order volumes, warehouse setup, and integration requirements.

For most Shopify retailers, yes. ShopFlow covers the operational requirements that Shopify retailers actually use from their ERP: inventory management, order processing and routing, returns and refunds, pick and pack, courier integration, and finance-ready reporting. The functionality that most retailers never use in NetSuite (global tax compliance, multi-entity consolidation, advanced project accounting) is not included in ShopFlow, which is why the price is dramatically lower.

If your business genuinely requires the full NetSuite feature set for reasons beyond Shopify operations (complex international tax, multi-entity group finance, etc.), the ShopFlow Integration Layer can handle the Shopify-to-NetSuite connection more effectively than standard connectors while keeping NetSuite for what it does that ShopFlow cannot replace.

A standard Full ShopFlow deployment for a mid-market retailer typically takes 6 to 12 weeks from kickoff to go-live. This includes the discovery and requirements phase, integration development, data migration, testing against your actual order flows, and team training. It compares very favourably to NetSuite or Brightpearl implementations that typically run 6 to 12 months.

The ShopFlow Integration Layer connecting Shopify to an existing ERP is usually faster, typically 4 to 8 weeks, because the ERP setup work is already done and ShopFlow is connecting to an existing system rather than replacing one.

Yes. ShopFlow connects to multiple Shopify storefronts simultaneously, maintaining a single inventory pool with real-time stock synchronisation across all of them. Orders from each storefront flow through the same fulfilment and warehouse workflows, and stock levels update across all connected stores as items are picked, packed, and despatched.

This is particularly relevant for retailers running separate consumer and wholesale stores, UK and international storefronts, or different brand storefronts from the same warehouse operation.

ShopFlow currently integrates with MetaPack, ShipStation, Royal Mail, DPD, and other major UK courier and fulfilment providers. The integration handles automatic label generation, tracking updates back to Shopify and customers, consignment management, and carrier selection rules based on order value, weight, destination, or custom criteria.

For couriers or 3PL providers not already in the ShopFlow integration library, Dev Partners can build the integration as part of the deployment. If your provider has an API, we can connect to it.

Yes. The ShopFlow Integration Layer is specifically designed for this situation. It acts as smart middleware between Shopify and your existing ERP, handling bi-directional data sync, order routing and enrichment, inventory synchronisation, and custom business rules that standard connectors like Celigo or Workato cannot accommodate.

It is more flexible than off-the-shelf connectors because it is built as a custom integration rather than a template-driven product. The data transformation rules, business logic, and error handling are written for your specific ERP configuration and Shopify setup. It is also typically less expensive than enterprise connector licensing at scale.

Yes, and this is one of ShopFlow's strongest areas. Fashion return rates of 25 to 40 percent are common, and without proper automation that volume of returns creates significant operational overhead. ShopFlow's returns module handles the full workflow: customer return initiation, carrier label generation, goods-in scanning, condition assessment, automatic stock reinstatement or quarantine routing, refund processing, exchanges, and store credit management.

The result is that returns are processed automatically without manual intervention at each step. Your customer service team handles genuine exceptions rather than processing routine returns manually, and your stock figures update in near real time rather than batching at the end of the day.

ShopFlow is hosted on Dev Partners UK servers. All data stays in the UK, making it GDPR compliant by design with no offshore data centres or third-party cloud providers involved. This gives you data sovereignty, eliminates cross-border data transfer compliance issues, and means you are dealing with a UK-based team directly for any infrastructure or compliance questions.

It also means no unexpected cloud cost escalation. Your ShopFlow licence cost is predictable because it is not tied to an AWS or Azure bill that can change with usage.

ShopFlow generates clean, reconciled financial data that integrates with Xero, QuickBooks, and Sage. The integration covers daily sales summaries, VAT reporting, payment reconciliation, and refund processing. Orders, refunds, and adjustments flow to your accounting platform automatically without manual re-entry.

For businesses with bespoke finance systems or specific accounting requirements beyond the standard integrations, Dev Partners can build a custom finance integration as part of the ShopFlow deployment.
