After a decade around agencies, I can tell you the most expensive hour in an agency is the unbilled one spent on a pitch that never closes. Vietnamese agencies, and foreign agencies setting up here, are being asked for sharper proposals in shorter time, often by clients who already use AI themselves. This playbook shows how to use AI to win new business faster without turning your pitches into interchangeable decks.
Why does AI change agency new-business in Vietnam?
Three pressures meet in the pitch room. Clients, especially foreign head offices, expect a proposal within days and often run several agencies against each other. Procurement teams want clearer scopes and KPIs. And your own team is already stretched on live accounts. AI does not remove those pressures, but it removes a lot of the low-value work inside them: research, formatting, first drafts and translation. If your team is still deciding who owns these tasks, see our guide to building an AI-ready marketing team and the team operations playbook.
Figures are directional rules of thumb from our client work, not audited benchmarks. Your results will depend on agency size, sector and how clean your case library is.
Which new-business tasks should AI handle?
Reusable prompts are what make this scalable. Store your pitch prompts, objection answers and proposal sections in a shared Vietnamese prompt library, and keep case studies and pricing notes in a searchable team knowledge base. Agencies that serve professional-services clients can also borrow ideas from our guide to legal and professional services marketing.
What separates a weak AI-made pitch from a strong one?
| Element | Weak (generic AI) | Strong (AI-assisted, human-led) |
|---|---|---|
| Opening | Agency credentials and logos | One sharp insight about the prospect’s market, with a source |
| Case studies | Unverified wins, vague numbers | Approved, anonymised cases matched to the prospect’s sector and stage |
| KPIs | Boost awareness and engagement | Baseline, target, method and review date for each KPI |
| Pricing | Copied from a template | Scope options with assumptions and what is not included |
| Localisation | Literal translation | Register and tone checked by a native strategist |
| Next step | Please contact us | A concrete 30-day start plan and a named lead |
What is a practical 7-step AI workflow for winning pitches?
This workflow works best when the agency has already decided what AI may touch. Keep client data inside approved tools and read our PDPL guide for marketers before pasting any customer information into a prompt.
How do you generate case studies with AI without overclaiming?
Case studies are the most reused asset in a pitch, so they deserve a process. Start with a one-page evidence sheet per project: objective, channel mix, dates, baseline, result, client approval status and who can verify it. Then prompt the model to write only from that sheet in three lengths (one line, one paragraph, one slide) and in the languages you need. Tag each case by sector, budget band, market and channel so a strategist can pull the right three in minutes. Never let AI supply a statistic, a client name or a quote that is not in the sheet. A foreign head office will often check, and one invented number can cost you the whole account. If the prospect is a foreign brand entering Vietnam, pair your cases with insights from our market research guide.
Can you be faster without lowering quality?
Yes, if you decide what speed means. The goal is not to send a proposal in six hours; it is to remove the dead time between a brief arriving and a strategist being able to think. In practice that means a same-day acknowledgement with clarifying questions, a research brief ready within an hour, a structured outline the next morning and a reviewed proposal within one to two working days. Anything faster should be a deliberate choice for a small, urgent opportunity. Track the numbers for a few quarters before you promise a turnaround time in your own marketing.
✓ Write the core insight yourself
✓ Red-team every proposal before sending
✓ Tell clients where AI helps and where people decide
⚠ Letting AI invent results or testimonials
⚠ Pasting confidential client data into free tools
⚠ Promising turnaround you cannot repeat
What mistakes do agencies make with AI-assisted pitching?
| Mistake | Why it hurts | Fix |
|---|---|---|
| One-size-fits-all decks | Prospects spot templated insight instantly | Require one prospect-specific fact per slide |
| No case governance | Wins get exaggerated or breached by NDA | Evidence sheet and client approval before use |
| Skipping the red-team | Vague KPIs reach procurement | Second prompt as sceptical CMO, then human review |
| Under-pricing for speed | Fast proposals with weak assumptions | Senior sign-off on scope, price and exclusions |
| No debrief | Same objections, same losses | Log win/loss reasons into the library |
