Develpreneur: Become a Better Developer and Entrepreneur Fixed Bid vs Time and Materials: Insights from Our Interview with Charly Leetham (Part 2)
Choosing the right pricing model can make or break a project, and understanding fixed bid vs time and materials is essential for developers, consultants, and business owners alike. In Part 2 of our Building Better Foundations interview with Charly Leetham, we explore the complexities behind scoping work, managing expectations, and balancing fairness with sustainability. This conversation dives into real experiences—both successful and painful—that highlight how important clarity is when building custom software or digital solutions.
About Charly LeethamCharly Leetham brings more than 40 years of hands-on experience in building practical, reliable systems for small businesses.

Fixed Bid vs Time and Materials: When Fixed Pricing WorksCharly begins by explaining that fixed bid pricing only works when the scope is tight, clear, and measurable. If she can define every deliverable—content length, number of pages, number of images, required effort—then fixed pricing is a win for both sides. Everyone knows what will be delivered and at what cost.
"Fixed bid requires fixed scope. If you can't list every deliverable, you shouldn't fix the price." – Charly Leetham
But when the work involves unknowns, research, or variable technical challenges, time and materials become the safer, more honest approach. When ambiguity is present, Charly often starts with a one-hour or two-hour discovery block before offering a detailed estimate.
Fixed Bid vs Time and Materials: Owning the EstimateOne powerful theme from Charly's perspective is ownership. If she commits to a fixed price and the work takes longer than expected—yet stays within the original requirements—she believes it's her responsibility, not the client's problem.
She compares it to car maintenance: if a mechanic quotes you a fixed price for an oil change, you don't pay extra because it took them longer internally.
"If I overestimated my abilities, that's on me—not the client."
Michael shares a similar story from his own experience: a large fixed-bid software project that went significantly over budget due to missed requirements and "muscle memory" business processes the client never mentioned. Even after months of discovery, unseen complexity still appeared late in development—forcing a learning experience the hard way.
Hidden Requirements: The Biggest Threat to Fixed Bid WorkOne of the biggest takeaways from the episode is how hidden systems and unspoken workflows can wreck a fixed price project.
Rob and Charly both describe situations where:
- Staff used spreadsheets leadership didn't know about
- Legacy systems connected to new tools in undocumented ways
- Workers avoided tools they disliked, creating shadow processes
- Teams hadn't been trained on the system they were supposed to use
- Business processes had evolved, but documentation had not
These are the real reasons fixed bids go off the rails. Not because developers fail—but because the truth of the workflow is often hidden beneath assumptions.
If you don't see the real workflow, your scope is incomplete.
Good requirements gathering means observing actual work—not just interviewing leadership.
Learning vs Billing: Handling Complexity FairlyAnother powerful point from Charly is knowing when to charge for expertise and when to absorb learning time. She tells a story about spending hours researching spam protection for a client. She only billed a fraction of that time, because much of it was her own learning. The next client benefited from that knowledge instantly—and paid a fair fixed price for the solution.
That balance of fairness and sustainability is what keeps clients trusting you long-term.
Final Thoughts: Getting Fixed Bid vs Time and Materials RightCharly ends with practical advice for developers: stay clear and intentional. Whether you're working fixed bid or time and materials, understand what you're building, pause when you're stuck, and talk through problems with someone. Much of the development clarity comes from simply stating the issue aloud.
In the end, fixed bid vs time and materials isn't just about pricing. It's about transparency, expectations, and knowing when each model protects both the client and the developer. With strong communication, clear requirements, and honest scoping, you set the foundation for projects that deliver value without surprises.
