eCommerce Agency Saves 1200 Hours on Marketplace Listings with Describely

A Five Person Agency Meets a 2500 Listing Wall

Tim Schweig founded VNDR to guide Europe-based eCommerce retailers through the maze of marketplaces such as Amazon and Bol.com, a marketplace primarily serving the Netherlands. Most clients shipped modest catalogs—some only 30 to 50 SKUs, others up to 500—and VNDR’s blend of in-house copywriting and brief ChatGPT prompts did the job. 

But when a luxury home-decor retailer asked the agency to optimize their 500-product catalog, with an additional 500 every season and a 2,000-item backlog, VNDR’s existing process was no longer sufficient. 

“ChatGPT wasn’t able to run through all these products. If we did them in batches of 5 or 10, it did work, but it would take a lot of time.”

Manual creation averaged 30 minutes per listing; at that pace Tim’s team faced roughly 1,200 hours of nonstop writing—four full work months—before the first holiday rush.

Custom Prompts at Scale

Early demos of Describely showed its focus around product content and SEO. But a collaborative onboarding with the Describely team was what unlocked the platform’s real power. Together, VNDR and Describely engineered a custom prompt that captured their client’s refined tone while juggling marketplace requirements—character limits, content templates, and multilingual requirements—without sacrificing speed. 

“I became convinced by the speed Describely produced all these descriptions,” Tim says, “With all of the variables taken into account and in such large quantities, I’d never seen that before.”

Watching Describely generate polished, on-brand copy for entire product batches in minutes convinced Tim the software could handle volume no other tool had mastered.

1200 Hours Reclaimed with Describely

With VNDR’s custom prompt in place, Describely returned ready-to-publish translated titles, descriptions, bullet points in multiple languages in “a matter of minutes”. 

Describely’s custom rulesets let VNDR avoid forbidden keywords for Amazon listings, remove bullet points for listings on Bol.com, integrate keywords into product titles, and create unique content suited for every length requirment automatically. Built-in translation capabilities delivered content in multiple languages, eliminating the usual back-and-forth with other translation services. The result was uniform, localized content that met each marketplace’s formatting requirements and preserved the brand’s tone of voice.

Tim estimates VNDR spent about 30 hours on prompt tuning and final reviews—saving roughly 1,200 hours compared with their previous workflow. The client pushed the content straight into their PIM with minimal rewrites:

“They were really happy with the results. It was much better than what they had on their own,” Tim reports.

A Gateway to Wider AI Adoption

Working with Describely transformed both VNDR’s client delivery and its internal operations, freeing the five-person team to focus on higher-value strategy.

“Describely opened my eyes that things could go much easier [with AI],” Tim says. “Now we’re going to see if we can build different workflows apart from content—like a lot of repetitive operational tasks that can easily be automated.”

Tim sums up VNDR’s Describely experience in three words: speed, consistency, and control. 

Describely handled the heavy lifting of large-scale content generation while giving the agency granular prompt access whenever they needed an extra tweak. For small teams managing oversized catalogs—or any brand that must meet multiple marketplace templates without expanding headcount—VNDR’s story shows how Describely turns a four-month bottleneck into a week’s work.
