How Black Cat Medicines scaled from 200 orders a week to 6,000 a day with StoreFeeder

From spreadsheets and paper picking to a fully integrated, multi-channel fulfilment operation.
Black Cat Medicines is an online veterinary pharmacy and pet supplies retailer operating across multiple sales channels. The business sells through two Shopify websites and marketplaces including Amazon, eBay, Tesco, B&Q, OnBuy and more.
As an omnichannel seller in a highly regulated industry, stock accuracy, batch tracking and fulfilment speed are mission critical.
Having partnered with StoreFeeder for over 10 years, the team has grown alongside the platform from its early days.
Before implementing StoreFeeder, Black Cat Medicines operated primarily through Amazon and eBay, processing between 100 and 200 orders per week.
Stock was managed using Excel spreadsheets. Orders were handled manually. Courier labels were created one by one. Warehouse picking relied heavily on paper pick sheets and individual staff knowledge.
If a key team member was off, finding stock could become a challenge. Scaling the business under that structure would have required significantly more back-office staff and introduced higher operational risk.
The processes simply were not built for volume.
Black Cat Medicines needed:
Most importantly, the business needed confidence that growth would not break operations.
StoreFeeder brought every sales channel into one centralised system. Orders from Shopify, Amazon, eBay, Tesco and other marketplaces flow into a single dashboard. Stock updates are pushed back out automatically.
The warehouse operation was completely transformed.
Paper pick sheets were replaced with barcode scanning, absolute pick locations and mobile app picking. The team now uses:
Shipping rules have become one of the most valuable features.
“They enable us to send items at the most suitable price and with the right courier, getting orders to customers quickly with very little manual input.”
The impact in the warehouse has been dramatic. Where hand-picking once limited output, mobile-guided picking now allows thousands of items to be picked per hour.
The move to digital workflows also eliminated vast amounts of paper. At one point, the business was printing up to 1,000 A4 pick sheets per day. Today, the only paper used is a thermal shipping label.
Since implementing StoreFeeder, Black Cat Medicines has scaled significantly:
“It’s that confidence in scalability that’s kept us with StoreFeeder. We’ve grown from a few hundred orders a week to thousands a day, and the system has scaled with us.”
The platform’s reporting and user permissions also give the business greater visibility and operational control. Individual packers can be tracked, performance can be measured, and system access can be tightly managed.
Operating on major marketplaces means strict performance metrics and deadlines. Missing KPIs is not an option.
Black Cat Medicines values the direct access and responsiveness of the StoreFeeder team.
“If something is critical, we can pick up the phone and get it fixed fast. That support is mission critical for us.”
Alongside direct contact with leadership, the business benefits from a detailed knowledge base and fast ticket support, ensuring operational continuity.
For businesses considering a WMS or ERP platform, the team’s advice is grounded in experience.
“There are other systems out there that can do similar things. But we know StoreFeeder inside out. It’s grown with us, and they understand our business the best.”
The long-term partnership, scalability and operational confidence have made StoreFeeder a core part of the business infrastructure.
Black Cat Medicines is a UK-based online veterinary pharmacy and pet supplies retailer operating across multiple ecommerce platforms. With strict stock rotation requirements and high daily order volumes, operational accuracy and speed are essential to their continued growth.
“StoreFeeder pulls every marketplace into one place, manages our stock profile, and allows us to ship thousands of orders a day efficiently. It’s scaled with us from day one.”
