The challenge
What needed to be true
Co-manufacturers run on margins where a single EDI rejection from a major retailer can mean chargebacks, missed ship windows, and lost shelf space. Most run on a patchwork of legacy tools that don't talk to each other.
ShiftERP needed a single system — production, inventory, and retail integration — reliable enough to trade with Walmart, Target, and Amazon, and built to scale as volume grew.
How we approached it
The approach, step by step.
02
Get EDI right
EDI integration with major retailers tuned to 99.5% accuracy — because at retail scale, the last half-percent is the difference between getting paid and eating chargebacks.
03
Engineer for load
AWS with EC2 Auto Scaling, RDS PostgreSQL, ALB, ECS, and CloudWatch — infrastructure that absorbs peak volume instead of buckling under it.
