Optimising your tech stack: A guide for CFOs

If you’re reading this, you’re likely looking to get the most from your tech stack. From my experience helping companies tackle these challenges, here are practical tips to ensure your tech is up to the task.

Is your tech stack fulfilling its purpose? Here's how to tell

When evaluating your tech stack, metrics are your best guide. Start by assessing data timeliness: if you’re stuck with quarterly data but need monthly, or monthly data but require weekly, that’s a clear sign the system isn’t meeting needs.

Another key indicator is team satisfaction. Regularly check in: is the system easy to use, or a constant headache? What worked at the start may no longer fit—listen to your team; their feedback is valuable.

Mapping out your integration obstacles

Integration problems show up when data differs across systems or you must manually combine data from multiple sources. If you’re repeatedly moving data by hand, your integration needs work.

If a full API integration isn’t possible, an automated CSV upload can help. There are many levels of integration; the goal is to minimize manual interventions and improve data flow, even if full automation isn’t feasible for every business.

Blueprinting your tech stack overhaul

Think of your tech stack as your processes—the stack will amplify any inefficiencies.

Begin with a thorough assessment of your current setup: what’s working, what isn’t, and what’s frustrating. This informs your needs analysis, crucial for defining expectations from a new system.

Don’t forget hardware. Outdated PCs and networks can hamper software performance. Ensure hardware can support your new investments.

Your tech vendor scouting guide

One common issue is entering with only a couple of problems in mind, which leads vendors to address those issues while missing broader needs. This often reveals new problems later.

Start with a comprehensive needs analysis and ensure the vendor can meet all requirements, not just a few. Don’t rely on promises—request demos to see solutions in action.

Do your homework: check reputation, read testimonials, and whenever possible, speak with existing clients or partners. Understanding timelines and costs upfront saves surprises later.

Bridging your team's tech know-how

Training timing is critical when rolling out new systems. Avoid training too early; many teams learn well before go-live but don’t actually go live for four to six weeks.

Schedule training close to go-live and ensure the right people focus on the most important parts for day one. You don’t need to know everything upfront; plan for follow-up training on less-critical areas after launch.

Ensure a support mechanism is in place. At BlueHub, we provide mandatory post-implementation support for 30 to 60 days, plus ongoing training plans to improve long-term adoption.

Lessons from tech stack revamps

At BlueHub, we’ve helped many companies revamp their tech stacks. A key lesson is to prepare your team for change and engage early with clear communication about what’s coming.

Data cleansing is another big item—older data often needs to be cleaned up. Decide early whether to migrate everything or capture a snapshot, and set realistic timelines.

Major overhauls typically take five to seven months from start to finish; managing expectations here smooths the process.

Future-proofing your tech

When deciding on your stack, consider growth plans. Ensure new systems can handle higher transaction volumes and are compatible with both current and future ecosystems.

Think three to five years ahead to avoid costly overhauls and ensure the stack grows with your business.

Optimising your tech stack is ongoing and requires careful planning and monitoring. By focusing on key metrics, ensuring solid integration, selecting the right vendors, and providing robust training and support, you’ll build a tech stack that boosts productivity and supports growth. Remember, a well-optimised stack isn’t just about technology—it empowers your team and drives your business forward.
