When an ecommerce replatforming project runs over budget or misses deadlines, development often gets the blame. In reality, most projects are already in trouble before a single line of code is written.
The biggest problems usually stem from poor planning, unclear objectives, weak requirements and a lack of stakeholder alignment. For mid-market businesses, getting these foundations right is critical.
1. Starting with Technology Instead of Objectives
Many businesses choose a platform first and work backwards from there. Whether it’s Shopify, Adobe Commerce or another solution, technology should support business goals rather than dictate them.
Successful projects begin with clear objectives such as increasing revenue, improving customer experience, reducing operational costs or supporting future growth. Once those goals are defined, selecting the right platform becomes much easier.
2. Overlooking Integration Complexity
The website is only one part of an ecommerce ecosystem. ERP, CRM, PIM, WMS and payment systems all need to work together.
Businesses often assume existing integrations can simply be moved to a new platform. In reality, many contain years of bespoke logic and operational workarounds. Without proper analysis, integration issues often emerge late and become expensive to fix.
3. Poor Requirements Gathering
Broad statements like “we need a better customer experience” are not enough to build a project around.
Detailed requirements covering customer journeys, business processes, fulfilment workflows, reporting and integrations help avoid assumptions that later lead to scope creep, delays and budget increases. A thorough discovery phase almost always saves time and money later.
4. Lack of Stakeholder Alignment
Marketing, operations, finance, customer service and IT all have different priorities. If these groups are not aligned from the outset, conflicting requirements and delayed decisions quickly follow.
Successful projects establish clear objectives, governance and decision-making processes early.
5. Failing to Understand Existing Problems
Many organisations know they want a new platform but struggle to explain exactly why.
Before investing in new technology, businesses should identify the real issues: inefficient processes, missing functionality, manual workarounds, customer frustrations or integration problems. Otherwise, there’s a risk of simply recreating existing issues on a new platform.
6. Unrealistic Timelines
Pressure to launch before peak trading periods or marketing campaigns often results in rushed projects.
Compressed timescales usually mean reduced discovery, incomplete requirements gathering, limited testing and increased technical debt. A realistic plan should allow sufficient time for design, development, testing, training and launch preparation.
7. Treating Data Migration as an Afterthought
Data migration is often underestimated. Duplicate customer records, poor product data and outdated content frequently surface during migration and can significantly impact delivery times.
Cleaning and validating data early reduces risk and improves long-term business performance.
8. Ignoring Scalability and Change Management
A new platform should support where the business wants to be in three to five years, not just where it is today.
Equally important is preparing people for change. New systems often introduce new processes and responsibilities. Without training and communication, user adoption can suffer regardless of how good the technology is.
Why Discovery Matters
Most of these risks can be addressed through a structured discovery phase. Discovery helps define objectives, assess integrations, align stakeholders, identify risks and create realistic budgets and timelines.
Too often it’s viewed as an optional cost. In reality, it’s one of the most valuable investments an organisation can make.
Success Starts Before Development
The most successful ecommerce projects aren’t necessarily those with the biggest budgets or newest technology. They’re the ones built on clear objectives, detailed planning and strong stakeholder alignment.
At PureNet, we’ve consistently found that the best project outcomes are achieved when businesses invest time in discovery before making platform or development decisions.
Because successful ecommerce transformation doesn’t start with development—it starts with understanding exactly what you’re trying to achieve.
