The situation
A private equity fund in Bengaluru has bought a majority stake in a pump manufacturer in Coimbatore. The founder keeps a minority stake and stays on as managing director. The fund's investment case rested on three ideas: grow exports, which are currently small; move the company from an old accounting package to a proper ERP so the fund gets reliable monthly numbers; and build a second line of management under the founder.
Day One went quietly. Now the fund's operating partner and the founder have to agree what happens over the next three months. The founder is wary of being managed. The fund is wary of a plan that drifts. Both want the same outcome, but they have not yet worked together.
Why a hundred days
The number is a convention. It is long enough to make real progress and short enough to keep attention. It also covers the period when employees, customers and competitors are watching most closely. Decisions made, or avoided, in these months set expectations for years.
Step one: write down why you bought it
Start with the investment case or deal thesis, in plain words. For the pump maker it is the three ideas above. For a competitor buying a competitor, it might be combined purchasing, shared distribution and one plant running at fuller capacity.
For each reason, write what has to be true in three months for it to be on track. Look for the evidence that it is moving. For exports: an export head hired or named, two target markets chosen, product certifications needed for those markets identified. For the ERP: requirements agreed, a vendor chosen, a cutover date set.
This list, usually five to eight outcomes, is your hundred day plan. Anything not connected to it is a candidate for later.
Step two: set up a small integration team
The integration lead
One person on the buyer side owns the plan. In a PE deal this is often the operating partner or someone they appoint. In a strategic acquisition it is a senior manager with time released from their day job. It should not be a part time task squeezed in around other work.
Workstream owners
Each outcome gets an owner, usually from the acquired business. The founder's people should own most workstreams. They know the business, and owning the work builds commitment.
A weekly rhythm
Hold one review a week, same day, same time, under an hour. Each owner reports status against their milestones, risks and anything they need decided. Decisions are recorded with the date and who made them. Monthly, report to the board or investment committee with a short summary.
Step three: measure a few things properly
Pick a small set of measures that show whether the business is healthy and whether the plan is on track. For the pump maker: monthly revenue and margin, order book, export enquiries, working capital days, and attrition of key staff. Agree the definitions once and keep them fixed. A measure that changes definition every month cannot show progress.
If the reliable numbers depend on the new ERP, say so and use the best available data in the meantime, with a note on its limits.
Step four: look after people deliberately
Uncertainty is the main cost of the first hundred days. People who can find other jobs, often the best people, will look if they do not know where they stand.
- Tell people what is decided as soon as it is decided, even if the news is mixed
- Meet the top twenty or thirty managers individually in the first month
- Agree retention terms for a few critical people where needed
- Where roles will change, plan the process carefully and follow labour law and the company's own policies, with advice from your lawyer
For a founder led business, the founder's relationship with the new owner is the single biggest factor. Agree early how decisions will be made, what needs the board, and what the founder decides alone.
Step five: handle systems with care
System changes such as the ERP move are often in the plan, and they often run late. Treat them as projects with their own scope, budget and acceptance criteria. Do not combine an ERP cutover with a financial year end or a peak season. Data migration needs special care with personal data in HR and customer records, which falls under India's Digital Personal Data Protection Act, 2023.
Step six: track risks openly
Keep a risk list from day one: customer losses, key staff leaving, a compliance gap found after closing, a supplier asking for new terms. Each risk needs an owner, a likelihood, an impact and a next action. Review it in the weekly meeting. A risk raised early is a planning item. A risk hidden until the board meeting is a credibility problem.
Limits
A hundred day plan cannot fix a bad price or a wrong thesis. If diligence missed something important, it will show up in these months, and the right response is to adjust the plan and say so plainly to the board. Some outcomes, especially culture and management depth, take longer than a hundred days. Set realistic year two milestones for them.
Where Synerger helps
Synerger's integration module holds the Day One, first hundred days and year two milestones in one plan, with Gantt style tracking, owners, risk identification and reporting, and performance measurement against the measures you choose. The engagement tools keep meeting agendas, action items and decision logs for the weekly review. If you want advisers alongside you, the Code Colonies consulting team can run the integration office with your people, and system work such as an ERP rollout can be delivered by the Code Colonies technology team on 2good.dev terms, where you pay after you accept the work. The calls about people, priorities and pace remain with the owners and management.
A short checklist
- Investment case written as five to eight outcomes with three month evidence
- One integration lead with real time to give
- Workstream owners, mostly from the acquired business
- A weekly review with recorded decisions, and a monthly board summary
- A short, fixed set of measures
- Individual meetings with key managers and clear decision rights for the founder
- System changes run as separate projects with acceptance criteria
- A risk list reviewed every week
- Year two milestones set for what cannot be done in a hundred days
