Inside the inflection points: A Q&A with BigCommerce’s Rachel Nolan

Scaling an ecommerce business isn’t just about selling more—it’s about knowing when your operations need to change before they start holding you back. We sat down with Rachel Nolan, Strategic Partner Manager at BigCommerce, to get her perspective on the order volume milestones where merchants typically hit friction, how successful sellers make the shift from manual to automated fulfillment, and why shipping automation is usually the highest-leverage investment a growing merchant can make.


Ecommerce Scaling Context

What are the most common order volume milestones where you see BigCommerce merchants need to fundamentally rethink their operations?

We consistently see three inflection points:

  • 50–200 orders/month: Merchants outgrow purely manual workflows.
  • 1,000–2,500 orders/month: Fulfillment, inventory, and shipping processes begin to strain.
  • 10,000+ orders/month: Systems, automation, and team structure must be intentionally designed to scale.

What’s important is that these aren’t just volume milestones, they’re complexity milestones. That’s where having an open, extensible platform becomes critical.

At what point do you typically see merchants start struggling with their current fulfillment processes?

Most merchants begin to struggle once they exceed a few hundred orders per month. That’s when manual label printing, order routing, and carrier rate shopping begin consuming disproportionate time and introducing errors.

Merchants that scale smoothly usually adopt shipping automation early, before fulfillment becomes a bottleneck, instead of reacting once things break.


Operational Challenge Points

What are the biggest operational bottlenecks merchants face when scaling from hundreds to thousands of orders per month?

The biggest challenges we see are pretty consistent:

  • Too much manual work in fulfillment
  • Shipping decisions being made order by order
  • Systems that don’t talk to each other
  • Limited visibility into shipping performance and costs

As volume increases, those small inefficiencies add up fast. Merchants that centralize and automate shipping workflows are able to remove a lot of that friction.

How do successful merchants handle the transition from manual to automated processes? What does that journey look like?

The most successful merchants don’t try to automate everything at once. They usually start with shipping, because that’s where they get the fastest return.

Our merchants typically start with ShipStation, our most downloaded shipping app in the app store, which allows them to move from manual label creation to automated workflows, things like batch label printing, rules based carrier selection, and centralized order management. Once that foundation is in place, it’s much easier to layer on additional automation as the business grows.

What are the most critical systems and integrations merchants need as they scale?

At scale, flexibility is everything. BigCommerce gives merchants a strong commerce foundation, but shipping and fulfillment automation is what keeps operations running smoothly as volume grows.

And it’s not just about the storefront. Most growing merchants are selling across multiple channels, so orders are coming from everywhere. The key is having systems that pull everything into one place for fulfillment.

When BigCommerce is integrated with a platform like ShipStation, merchants can centralize orders, automate workflows, and manage carriers without rebuilding their tech stack as they grow.


Technology & Automation Investment

At what order volumes do you recommend merchants start investing in shipping automation, and why?

We encourage merchants to think about shipping automation from day 1. There’s no reason anymore to go to a carrier’s website to print labels, when there are tools like ShipStation that make it super easy to print labels from any carrier you want, and with rates that are probably better than you can get on your own when getting started. It’s more of a question of “why wouldn’t you do it?”  

This shift typically gives merchants peace of mind. Instead of constantly reacting to orders, they can spend their time focusing on other operations & improving the business.

How do you advise merchants to evaluate whether they should build custom solutions vs. use existing platforms and integrations?

Our general advice is to avoid building custom solutions for problems that are already well solved. Shipping is complex, and maintaining custom logic around carriers, rates, and labels can get expensive and time consuming, fast.

For most of our merchants, using a platform like ShipStation, especially when it integrates directly with BigCommerce, is a much more practical and scalable option than building and maintaining something in house.

For rapidly growing BigCommerce merchants, what role do APIs and shipping integrations play in maintaining operational efficiency?

They’re foundational to everything our merchants do. BigCommerce is built to integrate easily with shipping partners, so orders, shipping updates, and tracking information flow automatically between systems.

That kind of connectivity becomes increasingly important as volume grows. It reduces manual work and helps merchants keep operations running smoothly even as complexity increases.


Team & Resource Scaling

How should merchants think about scaling their fulfillment team alongside their order volume?

Ideally, headcount shouldn’t scale at the same pace as orders. Automation should absorb as much growth as possible first.

We’ve seen merchants handle significantly more volume with the same team simply by automating shipping workflows. People should be added when it makes sense, not just because order volume increased.

What operational mistakes do you see merchants make when they’re in rapid growth phases?

The biggest mistake is waiting too long to automate. Merchants often push manual processes further than they should, and that usually catches up with them during periods of rapid growth like the holiday seasons, BFCM, etc.

Another common issue is choosing tools that are too rigid early on. Flexibility matters a lot when you’re scaling quickly.


Decision-Making Framework

Can you walk us through the decision-making framework you’d recommend for a merchant hitting their capacity limits?

I think asking questions like:

  1. Where are orders getting stuck?
  2. What processes are still manual?
  3. Which systems can scale without being replaced?

In many cases, shipping and fulfillment are the clearest constraints and also the easiest place to make improvements through automation.

What data points should merchants be tracking to make informed decisions about when and how to scale their operations?

Key metrics include fulfillment time, shipping cost per order, error rates, and how many orders each team member can handle.

Data-driven merchants scale more predictably and profitably.


International Expansion Timing

At what order volumes do you typically see merchants start considering international expansion, and what operational considerations come into play?

Many BigCommerce merchants start thinking about international shipping once their domestic operations are running smoothly.

At that point, managing multiple carriers, shipping zones, and service levels becomes more complex, which makes centralized shipping tools especially valuable.

How do successful scaling merchants handle the complexity of multiple shipping zones and carrier relationships?

They rely on automation and rules rather than manual decision-making. With the right shipping setup, merchants can automatically select carriers and services based on destination, cost, or delivery speed without adding operational overhead.


Success Stories & Metrics

Can you share any examples of merchants who’ve successfully scaled through these transition points?

We’ve seen BigCommerce merchants like Austin Bazaar and Saddleback Leather successfully scale by investing early in shipping automation. By integrating BigCommerce with ShipStation, they were able to centralize fulfillment, reduce manual work, and scale without having to replatform or rebuild core systems mid-growth.


Closing Advice

What’s the biggest mistake you see growing merchants make when it comes to ecommerce scaling?

Waiting too long to invest in operational infrastructure. Growth is exciting, but it exposes every weakness in your systems.

If a merchant could only invest in one operational improvement to support scaling, what would you recommend?

Shipping automation. It touches cost, speed, accuracy, and customer experience and it scales with your business.


Ecommerce scaling doesn’t have to mean rebuilding. The merchants Nolan described—the ones handling more volume with the same team—got there by putting the right infrastructure in place before they needed it. ShipStation integrates directly with BigCommerce to centralize orders, automate fulfillment workflows, and give you access to discounted rates across major carriers, without adding complexity to your stack.
