Business Development Manager Job Description

A Business Development Manager is the person paid to bring in revenue the company does not have yet. In marketing, that can mean working inside an advertising, PR or digital agency and selling its creative, media, content or performance services to brands, or working inside a brand, publisher or marketing technology company and opening new accounts, channel partners and co-marketing deals. Either way, the measure of the job is signed business, not activity.

The work starts with choosing targets. A Business Development Manager builds a prospect list by category, account size and fit, studies each company's current marketing, its agency roster and any recent leadership change, and decides where a conversation is worth having. BLS describes the parent occupation, sales managers, as people who develop plans to acquire new customers through techniques such as direct sales, cold calling and business-to-business marketing. In an agency, the same instinct shows up as a short list of brands whose problems match the shop's best case studies.

Next comes the conversation itself. First meetings are discovery: what the prospect is trying to fix, who signs off, what the budget cycle looks like and which incumbent agency or vendor already holds the work. From there the manager shapes an offer, writes or coordinates the proposal, and assembles a pitch team of strategists, creatives and media planners who will actually run the account.

Formal agency searches add their own paperwork and etiquette. Brands may run a search through a consultant, and the 4As, the trade association for US advertising agencies, lists agency search consultant interaction among the areas of business development it supports. It also publishes an ANA/4As Standardized RFI Template, for the request-for-information stage of a search.

Pipeline management is a weekly discipline. Business Development Managers log every contact and stage in a CRM such as Salesforce or HubSpot, forecast what will close and when, and defend those numbers in weekly reviews with agency leadership or a sales director. They price scopes with finance, clear contract terms with legal, and confirm with delivery teams that the work can be staffed before anyone signs.

The job does not end at signature. A clean handoff to the account lead, with notes on what was promised, who the decision makers are and what the client cares about, protects the relationship that the manager spent months building. In smaller shops, the same person may stay close to the account through the first months of work, looking for the next project to propose.

Outside the office, the role means showing up where buyers are: industry conferences, award shows, local ad clubs and category trade events. Publishing thought leadership, speaking on panels and keeping a steady stream of referrals from past clients and partners are all part of the job description, even if none of them shows up as a line item on the commission plan.

There is no license for business development. BLS says sales managers typically need a bachelor's degree and work experience as a sales representative, and that is a fair description of the path into this role as well. Degrees in business, marketing, communications or economics are typical starting points, and an MBA can help for some senior roles at holding companies, consultancies and larger martech firms.

Experience. As a rough guide, expect three to seven years in sales, account management, agency client service or partnerships before a manager title. Candidates who come from the client side, such as a brand marketing manager who has run an agency review, bring a buyer's view of how pitches are judged. Agency account directors who have grown existing clients can move into new-business roles because they already know how to scope, price and staff work.

Core skills.

• Prospect research: reading a target's ad spend signals, agency roster, earnings commentary and hiring patterns
• Discovery and qualification: separating real budget and authority from polite curiosity
• Proposal writing and pricing: scopes of work, rate cards, retainer versus project fees, and change orders
• Pitch management: running a timeline, rehearsals, chemistry meetings and leave-behinds
• Negotiation: payment terms, intellectual property, exclusivity and termination clauses
• Forecasting: honest stage definitions and close dates in the CRM

Tools. Salesforce or HubSpot for pipeline, LinkedIn Sales Navigator for account research, a contact database for email addresses and direct dials, Google Slides or PowerPoint for pitch decks, and DocuSign or a similar e-signature tool for contracts.

Outreach rules worth knowing. Anyone who prospects by phone needs to understand the Telephone Consumer Protection Act. In Declaratory Ruling FCC-24-17, the Federal Communications Commission confirmed that the TCPA's restrictions on the use of an "artificial or prerecorded voice" encompass current AI technologies that generate human voices, so such calls require the prior express consent of the called party absent an emergency purpose or exemption. A manager tempted to let an AI voice agent run cold calls should talk to counsel first.

Credentials. None are required, but a few are relevant. The Association of Strategic Alliance Professionals awards the Certification of Achievement, Alliance Management (CA-AM) and the Certified Strategic Alliance Professional (CSAP), which suit managers who build partner and channel programs. The Association of Proposal Management Professionals offers the APMP Foundation certification for people who write and manage formal proposals and RFP responses.

BLS does not count business development managers on their own; O*NET files the title under sales managers, an occupation with 637,080 jobs in its May 2025 wage survey. BLS projects sales manager employment to grow 4 percent from 2025 to 2035, about as fast as the average for all occupations, with about 47,300 openings a year on average. BLS expects many of those openings to result from the need to replace workers who transfer to different occupations or exit the labor force. The OOH ties demand to growth: as the economy grows, BLS writes, organizations will focus on generating new sales and will look to their sales strategy as a way to increase competitiveness.

For the marketing setting specifically, the May 2025 wage survey counted 7,110 sales managers in advertising, public relations and related services, with a median annual wage of $152,570. That industry row counts all sales managers in the sector, not business development titles specifically, which BLS does not report separately.

The 4As 2026 New Business Activity and Resources Survey, based on 2025 data from respondents who skewed heavily toward independent agencies (84%), reported that project-based work slightly outweighs agency-of-record engagements. The survey read that as a continued shift toward smaller, more flexible opportunities. For a Business Development Manager, a defined project can be a way into a brand without displacing its agency of record, and a first project is a chance to prove the team before a larger assignment comes up for review.

The same survey addressed technology directly. It found that AI, LinkedIn automation and prospecting databases are commonly used, but that they appear to support, rather than replace, relationship-driven growth. In practice, the tools can speed up account research, meeting prep and first-draft proposals, while the decisions that move a deal, such as which brands to chase, how to price a scope and who should be in the pitch room, still sit with people.

Deliverability is the other practical constraint on prospecting at scale. Google's Gmail sender guidelines tell senders to keep spam rates reported in Postmaster Tools below 0.3%, and set extra requirements for anyone sending 5,000 or more messages per day to Gmail accounts, including one-click unsubscribe on marketing messages. The guidelines exist to help senders avoid Gmail limiting sending rates, blocking messages or marking them as spam, so a careless cold-email sequence can hurt deliverability for the whole company's domain. Managers who understand authentication and list hygiene protect everyone's inbox placement.

The career ladder runs from Business Development Manager to senior manager, director of business development or new business, and then to a vice president of growth or chief growth officer title at agencies, or a head of partnerships or chief revenue officer role at technology companies. Some managers move into agency leadership or start their own shops. Others cross to the client side as marketing procurement or agency-relations leads, where knowing how pitches are built is an asset.

Dear Ms. Alvarez,

I am applying for the Business Development Manager position at Northline Creative. For the past five years I have led new business at a 60-person independent agency in Columbus, where I own the pipeline, write our proposals and run every pitch from first call to signed statement of work.

When I joined, nearly all of our growth came from two legacy clients. I rebuilt our target list around three categories where our case studies were strongest: regional healthcare systems, credit unions and outdoor recreation brands. I then set up a simple cadence in HubSpot that paired account research with personal outreach rather than volume sequences. Over three years we added eleven new clients, and the two largest started as small website projects that grew into retained social and paid media work.

I also care about how we pitch, not only how often. I introduced a go or no-go review before every RFP, which cut the number of pitches we entered and raised the share we won. For a credit union search last spring, I brought our media lead into the discovery call, learned the board was worried about member attrition rather than awareness, and rebuilt our proposal around a retention test. We won against two larger shops.

Northline's work for mission-driven brands is the reason I am writing. I see room to build a referral program with the nonprofit boards your leadership already sits on and to package your strategy workshops as a paid first engagement for new prospects.

I would welcome a conversation about your growth plans for next year.

Sincerely, Jordan Reyes
