Post Acquisition Integration and First 100 Days Plan

Formation-readiness facts

Day-one priority

Authority, cash, payroll, insurance, system access, safety, and service continuity.

Entity discipline

Keep accounts, approvals, contracts, invoices, and obligations assigned to the correct legal entity.

Integration choice

Operational coordination does not require an immediate legal merger or dissolution.

Record owner

Every task needs a named owner, deadline, evidence, dependency, and escalation path.

What should a buyer complete during the first 100 days after acquiring a small business?

During the first 100 days, confirm closing records, authority, bank access, payroll, insurance, licenses, contracts, customer continuity, cybersecurity, accounting, taxes, and state compliance. Assign each task to an owner and entity. Preserve separate records until counsel and tax advisers approve any merger, transfer, or wind-down.

• Days 0–30: secure authority, cash controls, insurance, payroll, critical access, and required notices.
• Days 31–60: reconcile contracts, licenses, systems, vendors, customer obligations, and financial reporting.
• Days 61–100: approve integration decisions, intercompany arrangements, compliance cadence, and any entity changes.

Interactive planning tool

Set the transaction and operating profile to identify where the integration plan needs the most control.

1. What did the buyer acquire?

   • Selected assets and operations: Assignments, new accounts, employee transition, and permit continuity need explicit owners.
   • Equity in the existing entity: Existing contracts and history remain, but authority, control, and change-of-control terms need review.
   • A mixed or multi-entity structure: The integration plan must distinguish each buyer, seller, and operating entity.

2. How prepared is the employee transition?

   • Payroll, benefits, roles, and notices are assigned: Owners and deadlines exist for the transition.
   • Only critical roles are mapped: Secondary obligations and communications remain open.
   • The transition is not documented: Continuity and compliance risks need immediate review.

3. Are bank, accounting, and system controls ready?

   • Access and approvals are documented: Named owners control credentials, payments, books, and backups.
   • Critical access is ready: Reconciliation and secondary systems still need work.
   • Access relies on the seller: Day-one control is not yet secure.

4. How dependent is the business on licenses or regulated approvals?

   • Continuity and responsible parties are confirmed: Current agency or professional guidance supports the transition plan.
   • Some approvals remain under review: The team has identified agencies and owners.
   • Requirements are unknown: Do not assume the seller's approval transfers.

Secure control without disrupting service

The first days should confirm who can bind each entity, move money, access systems, direct employees, communicate with customers, and respond to incidents. Keep the signed closing set, resolutions, ownership records, EIN evidence, insurance, bank authority, passwords, payroll instructions, and critical vendor contacts in a controlled handoff record.

An equity purchase may preserve the target's existing legal identity while changing control. An asset purchase may require new contracts, accounts, employment steps, permits, and customer notices. The integration plan must follow the actual agreement rather than a generic merger template.

Assign every workflow to an entity

After closing, invoices, contracts, payroll, tax filings, licenses, insurance, and customer communications should identify the entity that owns the obligation. Shared employees, systems, intellectual property, or cash movements between affiliates need documented treatment under professional guidance.

Do not dissolve or merge an acquisition vehicle because the transaction is complete. Counsel, tax advisers, lenders, insurers, and operators should confirm what the entity owns, owes, guarantees, licenses, or employs before any legal change.

Use the first 100 days to close evidence gaps

The plan should track unresolved diligence findings, closing deliverables, consent deadlines, license renewals, customer or vendor commitments, cybersecurity remediation, and accounting reconciliations. Each item needs an owner, due date, supporting evidence, and escalation route.

Lovie can support approved formations and registered-agent records when the group needs a new entity. It does not perform operational integration, merge entities, transfer permits, run payroll, or determine tax treatment.

Founder questions

Should the buyer merge the acquisition entity after closing?

Not automatically. The entity may own assets, debt, contracts, licenses, guarantees, or operating history. Legal and tax advisers should approve any merger, conversion, or dissolution.

What is the first post-acquisition control to establish?

Confirm authority and cash access first, alongside payroll, insurance, critical systems, and service continuity. The exact sequence depends on the agreement and operating risk.

Can Lovie run the first 100 days integration?

No. Lovie handles approved company formation and registered-agent support. The buyer and its legal, tax, accounting, HR, insurance, IT, and operating teams own integration.
