How do you choose a partner to develop your e-commerce software?

How do you turn references into meaningful evidence?

Seeing a logo from a similar industry is useful, but it does not describe the scope of the project. Ask which component the team built, what it took over and for how long it operated it. Within confidentiality limits, you can ask for anonymized process examples or verifiable deliverables. Do not treat someone else's revenue growth as a guarantee of results for your project.

In a reference call, look into not only on-time delivery but how changes and problems were handled. How did the team proceed when requirements were unclear? How was communication handled during post-launch failures? These questions reveal a working discipline that a sales presentation does not show.

What questions should the demo answer?

Give the candidate a real order scenario that you have written in advance. Add exceptions such as a wrong price, an out-of-stock item and a failed payment. Ask the candidate to separate which parts already exist, which are configuration and which are new development. A ready-made function and a roadmap plan are not at the same level of evidence.

After the demo, record the open items. Break down an answer like "we can do the integration" into data scope, data direction, error handling, responsible party and acceptance test. That way the choice shifts from the candidate with the most impressive interface to the candidate offering the best-verified solution.

Why is the acceptance criterion part of the proposal?

Instead of "mobile-friendly," write observable conditions, such as product selection, address entry and the return from payment completing on specified devices. Instead of "fast," define the measurement environment and the target response times. Targets should be set according to project conditions; a performance figure without context does not allow comparison.

Which working boundaries should be clear in the contract?

Delivery scope, excluded work, third-party fees and change management should be explicit. Access to source code, the development environment, documentation and account ownership should be defined separately. These items are project management checkpoints; the binding contract text should be prepared with the relevant specialists.

Separate the first response time from the resolution time in support. In an outage caused by a third party, what does the team monitor, what does it fix and what does it pass on to the relevant provider? If working hours and the critical-incident communication path are unclear, "support is available" is not enough.

How should the selection be documented?

First define the mandatory conditions; exclude any candidate that does not meet them from scoring. Score the remaining candidates on process fit, technical sustainability, communication and total cost. Setting the weights before seeing the proposals prevents changing the criteria to favor a candidate you come to like later.

Ask every candidate, PROJX Digital included, for the same evidence. A good partnership is built on ground where expectations can be written in a shared language from day one and where it is known how success will be verified.

Why should the handover rehearsal be discussed at the selection stage?

To understand a project's sustainability, ask how another competent team would take over the setup. Are the necessary accounts under the business's control, are the setup steps documented, are the dependencies known? A delivery that depends on settings on one person's computer carries operational risk even if the demo works.

You do not need to wait for a real separation to rehearse a handover. You can include rebuilding the test environment from the documentation in the acceptance scope. This request does not mean opening every access to everyone; the aim is for the necessary access to be handed over securely and traceably.

How do you assess a candidate's handling of uncertainty?

Ask about a business rule that has not been decided yet. A strong approach states the missing information and produces the questions that will validate the solution. Giving an unconditional "we can do it" to every question does not show that the scope is understood. The impact of the unknown on cost and schedule should be visible.

In the selection meeting, ask for a list of open points. For which item is discovery needed, which feature depends on an external provider, which work falls outside the existing product? These distinctions can reduce surprises later and make the way of working together visible before you choose.
