30-60-90 Day Plan After Closing

Executive Summary (TL;DR)

• The first 90 days after closing are when most “surprises” show up—cash flow timing, staff stability, customer churn, and hidden operational dependencies.
• Use a 30 60 90 day plan after buying a business to stabilize cash, protect key relationships, and build a repeatable operating cadence before you optimize or expand.
• Prioritize four controls immediately: cash visibility, access + authority, customer retention, and a clear transition period with the seller and key managers.
• Who should act: buyers/investors who just closed (or are within 30 days of closing) and want a practical plan that protects downside while setting up growth.

Why the first 90 days matter after closing

Closing isn’t the finish line—it’s the handoff from “paper value” to “operating reality.” You didn’t just buy assets and a P&L. You bought a living system: customer relationships, staff habits, vendor terms, a lease that may require landlord consent, and processes that either do (or don’t) survive without the prior owner.

A disciplined first 90 days is about reducing variance:

• Cash variance: timing of receivables, payables, payroll, taxes, and seasonality
• Customer variance: churn risk, top-account retention, and customer concentration
• People variance: retention of key employees, role clarity, incentives, and culture shock
• Operational variance: systems access, undocumented workflows, and “tribal knowledge”
• Legal/compliance variance: licenses, contracts, and lien clean-up (including UCC/lien search items you don’t want to discover late)

If you’re still shopping for deals, start by browsing active opportunities so you can benchmark what “good documentation” looks like: browse businesses for sale on BizTrader.

Day 0–7: stabilize, learn, and prevent avoidable losses

Think of the first week as “control the cockpit.” You’re not trying to improve everything—you’re trying to ensure nothing breaks while you learn what you actually bought.

1) Lock down access, authority, and approvals

Create a single list of “systems that move money or customers,” then confirm you have admin access:

• Bank accounts, merchant processing, payroll, accounting file(s)
• Email domains, website CMS, ad accounts, CRM
• POS/field service software, scheduling tools, inventory systems
• Cloud storage and the deal data room (make a local backup)

Set temporary approval rules:

• No new vendor commitments over a threshold without your signoff
• No pricing changes without a quick margin check
• No refund policy changes without front-line training

2) Establish cash visibility immediately

In the first week, you want daily awareness—not monthly reporting.

• Build a 13-week cash forecast (simple is fine)
• Confirm AR aging, recurring billing status, and collections workflow
• Confirm AP cadence and “must-pay” vendors
• Validate payroll timing, benefits billing, and tax deposit schedules

If the business was valued on SDE (Seller’s Discretionary Earnings) or EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), your job is to protect the underlying drivers of that cash flow—not just the headline number.

3) Communicate stability to staff and customers

Your message should be boring—in a good way:

• The mission stays consistent
• Jobs are stable (if true), and you’ll listen before making changes
• Service levels remain the priority
• The prior owner supports a structured transition period

For customers (especially B2B), identify “top 10 accounts” and schedule personal outreach. If there’s material customer concentration, don’t delegate this.

4) Confirm transferability: lease, licenses, and key contracts

Many post-close fires come from missed “permission steps,” especially in an asset vs stock sale:

• Asset sale: you may need new contracts, new permits, and new vendor onboarding (because the entity changed)
• Stock sale: contracts often remain in the same entity, but change-of-control clauses may still trigger

Make sure you’ve addressed assignment and consent requirements for the lease, equipment leases, and top customer/vendor agreements. If you want a structured way to organize this, use BizTrader’s guide on assignability of leases and contracts as a checklist framework.

5) Reconfirm what was promised (without starting a fight)

You’re not “re-trading” the deal—you’re verifying operational truth:

• Inventory counts and condition (if applicable)
• Equipment list and maintenance status
• Open work orders / backlog
• Any promised training, introductions, or documentation delivery

If something is missing, document it calmly and tie it to the purchase agreement’s schedules and deliverables.

30 60 90 day plan after buying a business: your operating cadence

You’ll hear the phrase “30 60 90 day plan after buying a business” in every acquisition circle because it works: it forces sequencing. The mistake is using it as a motivational poster instead of an operating system.

Below is a cadence that fits most small and lower middle-market acquisitions—whether the deal involved add-backs, a seller note, or an earnout.

First 30 days: verify reality, keep customers, and document how the business runs

Primary objective: stabilize revenue and service delivery while you learn the “real org chart” (who actually makes things happen).

Focus areas

• Customer retention: top accounts contacted, service levels monitored, churn risks logged
• People + roles: confirm who owns sales, ops, scheduling, invoicing, collections, and vendor ordering
• Process mapping: document the 5–10 workflows that produce revenue (lead → quote → deliver → invoice → collect)
• Metrics baseline: track a small KPI set weekly (sales pipeline, gross margin, labor %, on-time delivery, cash collections)

Quick wins that don’t break the machine

• Fix obvious quoting/invoicing leakage
• Tighten collections cadence (polite, consistent)
• Standardize how work is scheduled (reduce chaos, protect staff morale)
• Remove “double work” in admin tasks

Avoid in the first 30

• Rebranding, major pricing changes, big software migrations, comp plan overhauls

Days 31–60: standardize operations and build reporting you can run weekly

Primary objective: create repeatable management routines and reduce dependence on any one person (including you).

Focus areas

• Weekly operating meeting: same agenda, same numbers, same owners
• Monthly close discipline: accurate books within a predictable timeframe
• Vendor and margin review: confirm negotiated terms, rebates, and true cost structure
• Quality control: define “done” standards and customer feedback loop
• Working capital plan: ensure the business has enough liquidity to operate without heroics

If your purchase included a working capital target/peg, re-check whether your actual cash needs align with the assumptions. “Profitable” businesses still fail from working capital mismanagement.

Days 61–90: lock in growth levers and reduce owner-dependence

Primary objective: pick 1–2 growth levers and execute them with measurement, not vibes.

Focus areas

• Sales motion: define your pipeline stages, follow-up SLAs, and close reasons
• Marketing attribution: even basic “where did the lead come from?” tracking helps
• Hiring plan: only after you’ve stabilized roles and workflows
• Risk reduction: address single points of failure (key employee, key vendor, key channel)

If the deal includes an earnout, align metrics definitions early. Ambiguity turns into conflict. Get definitions in writing and keep reporting consistent.

Valuation lens: protect the cash flow you paid for

Most buyer regret comes from paying for cash flow that doesn’t survive ownership change. Use valuation logic as a post-close operating guide:

SDE vs. EBITDA (and why it matters in the first 90 days)

• SDE (Seller’s Discretionary Earnings): typically used for owner-operator businesses; includes owner compensation and discretionary expenses plus legitimate add-backs.
• EBITDA: more common as operations scale or when management is in place.

Post-close, your job is to validate that the add-backs were real and that the cost structure doesn’t “snap back” higher under your ownership (e.g., you need to replace owner labor with a hired manager).

Working capital is the silent deal term

Even a clean purchase price can go sideways if the business needs more cash to operate than expected. Watch:

• AR days drifting longer
• Inventory creeping up
• Vendor terms tightening
• Seasonality that wasn’t obvious in annual statements

Customer concentration and key relationships

If the top 1–3 customers represent a meaningful share of revenue, treat retention like a separate workstream:

• Relationship mapping: who trusts whom, and why?
• Contract review: renewal dates, change-of-control clauses, service levels
• Red flag watch: delayed POs, lower order frequency, higher complaints

Deal structure terms affect behavior

• Seller note: align payment schedule with realistic cash flow and reinvestment needs
• Earnout: define metrics precisely and keep reporting transparent
• Asset vs stock sale: affects contract transfer, tax allocation, and how liabilities may carry over (consult pros)

Deal process overview (NDA → LOI → diligence → close) and what still matters post-close

Even though you’ve closed, the classic flow matters because it defines the documents you now rely on:

• NDA (Non-Disclosure Agreement): confidentiality; useful if you later share info with lenders/partners
• CIM (Confidential Information Memorandum): the “story” of the business—validate it against reality
• LOI (Letter of Intent): outlines major terms; helpful reference when disputes arise
• Diligence: financial, legal, operational confirmation; post-close you’ll often “finish” diligence in practice
• Close: purchase agreement, schedules, bill of sale, assignments, non-compete (where applicable), transition commitments

Two post-close items buyers should not ignore:

1. UCC/lien search follow-through: confirm releases were filed and recorded where required, and that secured parties are cleared appropriately.
2. Reps & warranties tracking: your purchase agreement likely includes representations and warranties (reps & warranties). Create a simple log of key representations and any facts you discover that might touch them—timelines matter.

Post-close due diligence checklist (with table)

Use this as a “confirm and operationalize” checklist—what you verify, who owns it, and when you want it done.

Area	What to confirm post-close	Evidence to collect	Owner	Target timing
Financials	Bank recs, AR/AP accuracy, revenue recognition basics	Bank statements, AR aging, AP aging, GL detail	Buyer + bookkeeper	Week 1–2
Cash controls	Approval limits, payment workflows, fraud prevention	New approval policy, vendor master list	Buyer	Week 1
Taxes	Filing calendar, payroll tax cadence, sales tax nexus exposure	Prior filings, agency accounts access	CPA/payroll provider	Week 2–4
Customers	Top accounts contacted; churn risks logged	Call notes, renewal dates, pipeline report	Buyer + sales lead	Week 1–4
Contracts	Assignment/change-of-control compliance; renewals	Executed assignments, consents	Attorney/ops lead	Week 1–6
Lease	Assignment + landlord consent (if required); options and use clauses	Lease, amendments, written consent	Buyer	Week 1–6
Liens	UCC filings, payoff letters, releases filed	UCC search results, lien releases	Attorney/closing team	Week 2–6
People	Org chart reality; retention plan for key staff	Role descriptions, comp summary	Buyer + manager	Week 1–4
Operations	Critical workflows documented; QC standards defined	SOP drafts, checklists	Ops lead	Week 2–8
Tech/data	Admin access; backups; security hygiene	Access list, password manager, backups	Buyer/IT	Week 1–3
Inventory/assets	Condition + count (if applicable); maintenance schedule	Asset list, maintenance logs	Ops lead	Week 2–6
Risk/insurance	Coverage matches reality; COIs updated	Policies, endorsements	Broker/agent	Week 1–3
Reporting	Weekly KPIs and meeting cadence established	KPI dashboard, meeting agenda	Buyer	Week 2–6
QoE follow-ups	Any remaining “open questions” from QoE	QoE (Quality of Earnings) report notes	Buyer + CPA	Week 2–8

Note: QoE (Quality of Earnings) is a diligence analysis that tests whether earnings are repeatable and properly stated—especially useful when add-backs and owner involvement are significant.

Myth vs. Fact: common first-90-day mistakes

• Myth: “I need to change everything fast to justify the acquisition.”
  Fact: Speed matters—but sequencing matters more. Stabilize, then optimize.
• Myth: “If the financials were clean in diligence, I’m safe.”
  Fact: Diligence reduces risk; it doesn’t eliminate operational surprises.
• Myth: “Customers won’t notice ownership change.”
  Fact: They notice changes in response time, consistency, and who answers the phone.
• Myth: “The seller will be available whenever I need them.”
  Fact: Treat the transition period like a contract deliverable: schedule it, document it, and use it.
• Myth: “Staff will stay if the business is ‘healthy.’”
  Fact: Staff stay when expectations, roles, and communication are clear—especially during uncertainty.

Decision matrix: what to change now vs. later

Use this table to avoid “change for change’s sake.”

Decision area	Change in first 30 days	Change in days 31–60	Change in days 61–90
Pricing	Only if you can prove margin leakage or obvious mispricing	Pilot on a subset; track close rate + complaints	Roll out broadly if data supports
Staffing/roles	Clarify responsibilities; avoid reshuffling titles	Adjust structure to reduce bottlenecks	Hire for proven gaps
Vendor changes	Only if supply risk or cost is clearly out of line	Renegotiate terms; dual-source where possible	Consolidate vendors for scale
Marketing	Keep campaigns running; fix tracking	Improve lead quality and follow-up discipline	Scale the best-performing channels
Software migrations	Avoid unless critical risk	Plan migration with process owners	Execute after workflows are documented
Hours/service model	Avoid major changes unless customer pain is clear	Pilot changes with staff input	Implement with training + QA
Brand/rebrand	Avoid	Evaluate customer sentiment and differentiation	Consider only if it supports strategy

Execution plan: a practical 30/60/90 schedule

Below is a concrete schedule you can run without a big corporate integration team.

Days 1–7 (control the cockpit)

• Confirm all access (banking, payroll, CRM, email, POS)
• Establish daily cash check (collections, payables, payroll timing)
• Meet key staff 1:1; identify “who makes it work”
• Call top customers; schedule recurring check-ins
• Validate lease/contract assignment steps and any required consents
• Create a single “issue log” (owner, due date, status)

Days 8–30 (stabilize + document)

• Set a weekly operating meeting (same time, same agenda)
• Start SOP capture for quoting, scheduling, delivery, invoicing, collections
• Validate add-backs and confirm the “true” cost to run without the prior owner
• Build a simple KPI dashboard and review it weekly
• Confirm inventory/asset condition and maintenance schedule
• Write a 90-day retention plan for key employees and top customers

Days 31–60 (standardize + improve)

• Tighten close process with your bookkeeper/CPA (predictable reporting)
• Review vendor terms; address margin erosion
• Improve pipeline discipline: follow-up cadence, stage definitions, win/loss notes
• Address bottlenecks (scheduling, dispatch, quoting capacity, approvals)
• Reduce single points of failure: cross-train, document, delegate

Days 61–90 (scale what works + reduce risk)

• Choose 1–2 growth levers (not five): upsell, referral, PPC optimization, route density, etc.
• Implement performance management basics: scorecards, expectations, feedback loop
• Finalize your “owner independence” plan (what you will not personally do by day 120)
• Reassess deal terms tied to performance (earnout/seller note) with clean reporting
• Build your next 12-month operating plan (budget + hiring + capex)

If your acquisition used SBA financing, it’s worth understanding what smooth lender-ready reporting looks like for future deals. BizTrader’s overview on SBA 7(a) buyer financing is a helpful reference for what lenders tend to scrutinize.
