SUCCESS STORY

Mast General streamlines same-day eCommerce shipping and tax compliance

Mast General needed to modernize its 100-year-old business with eCommerce while keeping up with changing economic nexus laws for online sales.

The company also needed real-time inventory and reporting to improve accuracy across the business.

With Celerant, Mast General automates online order fulfillment, reducing manual work and helping orders ship the same day.

THE JOURNEY

Challenge → Solution → Results

A strategic partnership built on understanding, innovation, and measurable outcomes.

CHALLENGE

Outdated systems slow fulfillment and reporting

Mast General relied on an outdated POS system that made reporting, inventory and online order fulfillment difficult. Complex economic nexus laws also made accurate sales tax reporting harder to manage.

Slow reporting: The old POS required nightly batch reports instead of providing timely business data
Inefficient fulfillment: Staff had to manually choose fulfillment locations, extending shipping times
Inventory and tax challenges: Stock visibility was limited, while changing nexus laws complicated sales tax compliance

SOLUTION

Smarter fulfillment and tax improve eCommerce

After switching to Celerant, Mast General gained real-time visibility across stores and online sales, making eCommerce orders easier to fulfill from the best available location.

Best-store fulfillment: The system selects the best location for each online order to reduce shipping time and cost
Avalara tax automation: Online sales taxes are calculated and reported across tax jurisdictions for easier compliance
Real-time inventory and accessibility: Store and online inventory stay connected, while AudioEye helps make the eCommerce site more accessible

RESULTS

Same-day shipping with easier tax compliance

With Celerant in place, Mast General now serves customers nationwide with a more automated and efficient fulfillment process, while Avalara helps keep online sales tax reporting compliant.

Real-time inventory visibility down to the store level allows the system to select the best location to fulfill each eCommerce order based on preset logic.

Because all stores and online sales operate through one real-time database, Mast General no longer relies on nightly batch reporting and can access accurate business data from anywhere.

“

Considering we ship online orders from our multiple stores to our customers all over the country, leveraging Celerant's ‘Best Store Fulfillment’ has enabled us to expedite our fulfillment process to most orders now being shipped same-day, from a previous average of 3-5 days.
