What is business development? Meaning, process and strategy for B2B firms
Updated By the SalesOne research team9 min read
The short answer
Business development is the work of creating new revenue opportunities: finding the companies and partners worth working with, building relationships with them, and turning the right ones into clients. In professional services, consulting and engineering firms it usually means winning new clients before they issue a request for proposal, through research, introductions and a clear point of view.
What does business development mean?
Business development means creating the opportunities that sales then closes: new clients, new markets and partnerships. In many professional firms the two words simply mean winning new work.
The term covers different jobs in different companies. In a software company it often means partnerships or an outbound sales role. In accounting, architecture, engineering, consulting and recruitment firms it usually means the partners’ and principals’ work of finding and winning new clients, because those firms rarely have a sales team.
What is the difference between business development and sales?
Business development decides where to look and opens the door; sales takes a qualified opportunity to a signed contract. In small firms the same person often does both.
| Item | Business development | Sales | Marketing |
|---|---|---|---|
| Main job | Find and open new clients, markets and partners | Turn qualified opportunities into contracts | Build awareness and demand at scale |
| Works on | Accounts and relationships | Deals | Audiences |
| Measured by | Qualified conversations and new relationships | Revenue closed and win rate | Reach, engagement and leads |
| Time horizon | Months ahead of a purchase | Weeks to close | Ongoing |
What is the business development process?
A repeatable business development process has six steps: choose who to serve, find companies with a reason to change now, research them, reach the person who owns the problem, qualify, and hand over or close.
- Choose who to serve. Write an ideal client profile as rules you can check.
- Find companies with a reason to change now: a new leader, a new site, an acquisition or a project named in a job post.
- Research each one and record why it is kept or turned down.
- Reach the person who owns the problem with a short, specific message.
- Qualify on a first conversation: the problem, the owner, the timing and a next step.
- Close the work, or hand it to the partner or salesperson who will.
Timing is why the early steps matter. Forrester (blog, Feb 24, 2026, from its 2025 Buyers’ Journey Survey) found that 68% of B2B buyers already have a front-runner vendor in mind at the start of their purchase, and that the front-runner wins 80% of the time. Business development is how a firm becomes the front-runner.
What makes a good business development strategy?
A good business development strategy is narrow and timed: a short list of client types, the events that create work for you, and a weekly routine for reaching those companies before they go to market.
| If most new work comes from | The risk | Add |
|---|---|---|
| Referrals | Feast and famine; growth depends on others | A weekly list of companies with a dated reason to talk |
| Requests for proposal | Arriving after the buyer has a favorite | Contact before the request is written |
| A few large clients | Losing one changes the year | Two or three new clients a year in a second segment |
| Events and networking | Many conversations, few follow-ups | A follow-up plan for every event |
How does business development work in each industry?
The method is the same everywhere, but the events that create work, and the people who decide, differ by industry. Our industry guides cover each one.
- Accounting firms: accounting firm business development.
- Architecture firms: architecture firm business development.
- Engineering firms: engineering firm business development.
- Consulting firms: how to get consulting clients.
- Executive search firms: executive search business development.
- Recruitment and staffing agencies: recruitment agency business development.
- Fractional executives: how fractional executives find clients.
What does a business development week look like?
Here is a realistic week for a partner at a fictional 40-person engineering firm who spends about a day a week on business development.
| Day | Activity | Output |
|---|---|---|
| Monday | Review new permits, expansions and leadership changes in the target region | 12 companies with a dated event |
| Tuesday | Check each against the client profile; record why each is kept or turned down | 5 kept, 7 turned down with a reason |
| Wednesday | Find who owns the project at each kept company | 9 people, each with a dated source |
| Thursday | Send five short notes naming the event, each approved before sending | 5 messages sent |
| Friday | Follow up on last week’s replies and book calls | 2 calls booked |
How do you measure business development?
Measure the activities that lead to work, not only the work won: qualified accounts, conversations held and proposals invited, alongside new clients.
- Qualified accounts added each month, with a reason to talk now.
- Conversations held with the people who own the problem.
- Proposals invited before a formal request was issued.
- New clients won, and revenue from clients won in the last two years.
How does SalesOne help with business development?
