An ERP is the one system that holds your stock, orders, suppliers and finances. We build custom ERPs and connect them to your storefronts, marketplaces and accounting, as we did for BuffyHub, which runs Amazon, eBay and Walmart from one place.

An ERP earns its keep when stock, orders, suppliers and money stop living in separate tools that nobody fully trusts.
Core capability
One record of stock and orders that every channel reads from. Westar pulls orders from several storefronts and batches them for picking and packing.
Billable hours, invoices and accounting sync. ATC sends billable hours to Zoho Books and generates invoices from them.
Staff records, roles and approvals in the same system as the work. ATC holds HR information for hundreds of employees.
Vendor records and stock feeds that update themselves. Autobuffy pulls vendor inventory automatically instead of importing spreadsheets.
Bookings, parts stock and billing for service businesses. Mi Taller runs automotive workshops this way.
Project story · BuffyHub
BuffyHub gives online sellers one place to run inventory, orders, brands and vendors across Amazon, eBay and Walmart. As volumes grew, the platform had to hold far more data and traffic without slowing down or going offline.
Inventory, order, brand and vendor records were growing fast, and the existing setup was not built to store or serve that much data. Busy periods slowed pages down, no single integration connected all the selling channels, and the stored data needed stronger protection.
Sellers run their whole catalog and order flow from one platform that handles more traffic and keeps their data protected. Most ERP work comes down to this: one reliable record of stock, orders and suppliers that every channel reads from.

KubernetesMost companies should start with an off-the-shelf ERP. Building your own makes sense in a few specific cases, and these are the questions we ask first.
If you sell through marketplaces, wholesale and your own store, and no product syncs them the way you work, a custom core can. BuffyHub runs Amazon, eBay and Walmart from one place.
Manufacturers and service firms with their own way of costing jobs often lose that detail inside a standard ERP.
Large suites charge for breadth. A focused system that covers your real workflows can cost less to run.
Accounting, shipping, payments and storefronts. Integration is usually the bulk of an ERP project, so we scope it first.
If an established product covers your processes, use it and build only the integrations or reports it lacks.
Move one area at a time, such as inventory first and invoicing next, so the business never runs on a half-finished system.

What operations and finance leads ask before replacing their back office.
Building the system that holds your stock, orders, suppliers and finances in one place, then connecting it to the tools around it: storefronts, marketplaces, accounting, shipping and payments.
Buy if an established product covers your processes. Build, or extend one, when your channels, costing or workflows are what the standard products get wrong.
Yes. On BuffyHub we connected payment gateways, shipping providers and inventory systems through APIs and webhooks, so data flows between them automatically.
One area at a time. We migrate and check the data for each part, run old and new side by side where needed, and switch over once the numbers match.
It has to be designed for that from the start. BuffyHub runs on Amazon RDS, S3 and load-balanced EC2, so it takes on more data and traffic without downtime.
You do. Everything we build for you, including the source code and the intellectual property in it, belongs to you.
