How much notice should I give?

At minimum 30 days for customers, 60 days for vendors with open accounts, and as much as legally required for employees (varies by state and by WARN Act obligations for businesses over 100 employees). If you can give more, do — customers especially appreciate time to transition. For smaller businesses without WARN obligations, 45-60 days is considered respectful.

Should I send separate letters to customers and vendors?

Usually yes — the information they need is different. Customers need to know about refunds, gift certificates, final sales, where to go next. Vendors need to know about outstanding invoices, final orders, and wind-down timelines. Combined letters work for small businesses with a tight-knit base, but separate is cleaner for larger ones.

Should I explain why I'm closing?

You can, but you don't have to. Retirement is warm to share. Health reasons can be mentioned briefly and dignifiedly. Financial difficulty is more sensitive — a simple "after careful consideration, I've decided to close" is often all anyone needs. You owe customers an announcement; you don't owe them a full explanation.

What about employees and their final pay?

State laws vary on final-paycheck timing — some require payment on the last day of work, others within a set number of days. Consult your state labor department or an HR advisor. Benefits continuation (COBRA for US health insurance) is federally regulated for businesses of 20+ employees. Gather payment, benefits, and reference-letter details before the announcement so you can answer questions on the spot.

How formal should the letter be?

Appropriately formal for your industry. A professional services firm (legal, accounting, medical) leans more formal. A neighborhood bakery can be warmer and more conversational. The tone you select in the form matches to the register — grateful-warm for a beloved local business, brief-formal for a professional practice.

Should I include my new contact info after closing?

If it's relevant. For retirements, "you can reach me at [personal email] for personal correspondence" is kind. For closures with referrals, include the referral's contact info prominently. If you're genuinely disappearing from the industry, no contact info is fine — the letter can simply close.

Closing a business you've built

After years — sometimes decades — of running a business, the decision to close is rarely sudden. Retirement, the sale of the practice, a move, health reasons, a market that's shifted too far. Whatever the reason, once the decision is made, one of the hardest tasks left is writing the announcement. How you say you're closing says almost as much about who you've been as a business owner as what you did while you were open.

A good closure letter is honest, brief, specific, and warm. It thanks the people who made the business possible. It gives the practical information they need — what happens to their account, where they can go next, when the doors actually close. And it signals the kind of ending you want people to remember, rather than the kind you're trying to avoid.

Who needs to be told, and when

The audience matters. A letter that works for customers may not work for vendors; a letter to employees is its own thing again.

Customers: usually get the most emotional, most grateful version of the letter. Give 30 to 90 days' notice where possible. They need to know: when the business is closing, where (if anywhere) you're referring them, what happens to pending orders or appointments, whether there's a final sale or inventory to collect, how to reach you with questions. Professional services (doctor, dentist, attorney, financial advisor) should err toward longer notice — your clients need time to transition.

Vendors and suppliers: get a more factual, business-like letter. Give 60 days' notice where feasible, especially if they have open accounts or recurring deliveries. They need to know: the closure date, how outstanding invoices will be handled, the timeline for final orders, and who to contact with administrative questions.

Employees: get told first, in person where possible, before the letter goes to anyone else. A written letter is still useful for documentation and for practical details — final paycheck timing, benefits continuation, reference letter availability, transition bonus if applicable. Check state labor law (final-paycheck timing varies by state) and federal rules (WARN Act for businesses of 100+ employees requires 60-day notice for mass layoffs).

The broader community: for many small local businesses, there's a community who cared about the business beyond the direct customers. A neighborhood café, a bookstore, a local shop. A short announcement — email newsletter, social media, local paper — closes the loop with people who will miss the place.

Tone, by reason

Retirement: naturally grateful and forward-looking. You've had a full run. Thank customers by name if you know many by name. Mention the length of the tenure explicitly. Keep the tone warm.

Sale to a new owner: the tone is more about continuity than closure. "The business continues. I'm thrilled to introduce [new owner], who has..." Emphasize that customers don't lose the place; they gain a new steward.

Relocation: straightforward. Regret at leaving the location, gratitude for the years there, information about where (if anywhere) they can find you.

Unable to continue (health, financial): dignified and brief. You are not required to explain yourself. "After careful consideration, I've decided to close" is a complete sentence. If the reason is health and you want to be specific, say so — "following a health diagnosis that will require my full attention." Do not get into financial specifics unless you've decided that's what you want to do.

Industry downturn: acknowledge the broader context briefly, without blame. "In an industry that has changed dramatically, we've decided..." Thank customers for their loyalty. Look forward where you can.

What to avoid

Over-explaining the reason. You owe customers an announcement. You don't owe them a full justification. Often brief is kinder — to them and to you.

Making promises you can't keep. "I'll stay in touch with each of you personally" is only true if you will. "You'll be the first to know about my next venture" is only true if there will be one.

Bitter or negative framing. Even if the closure is forced by circumstances you didn't choose, the letter is not the place to litigate the reasons. Save that for conversations. The letter is for gratitude and logistics.

Generic hype. "It's been an amazing journey," "an incredible ride," "we couldn't have done it without our amazing community" — these phrases read as filler. Specific beats generic: "In our 27 years, we've watched three generations of families come through these doors." That lands.

What to include in practical terms

Customers want to know:

Closure date (or key transition dates if phased).
What happens to accounts, pre-paid services, deposits, gift certificates, appointments. Spell this out. "Gift certificates issued before [date] will be honored through [final date]. After that, please email us for a refund at [address]."
Referral, if any. Who to go to next. For professional practices, this is the most important information in the letter.
Final sale information, if applicable. Dates, what's discounted, how to pay.
Contact for post-closure questions. An email address that will be monitored for at least 6-12 months after.

Vendors want to know:

Closure date and final-order cutoff.
Outstanding invoice plan. When you'll pay them out.
Account closure timeline. When they should stop recurring deliveries, cancel standing orders.
Administrative contact.

Employees want to know:

Last day of business.
Their individual employment end date (may differ if staggered).
Final paycheck timing and delivery method.
Benefits continuation (COBRA for US businesses with 20+ employees, state-specific options).
Reference letter availability.
Any transition bonus or severance.
Expected assistance with job search (if offered).

Legal and administrative wind-down

Not the letter's job, but worth noting. You'll need to handle:

Final payroll tax filings
Sales tax returns and final deregistration
Business license cancellation
Insurance policy termination
Commercial lease end (if applicable)
Utility cancellation
Banking and credit card closure
Entity dissolution with the state (LLCs, corporations, partnerships)
Final federal tax return (including the "final return" box checked)

A CPA, an attorney, or a wind-down service can coordinate these. Budget 3-6 months to fully close out a small business; longer for one with significant assets or employees.

A short example

To customers, retirement:

Dear friends,

After 31 years behind the counter at Main Street Books, I've decided it's time to retire. Our last day open will be June 30, 2026.

It has been the privilege of my working life to run this store. I've watched children grow up into parents who bring their own children here. I've recommended books I loved to people who became friends because of them. I've had the best staff any bookseller could have asked for, and I'm grateful to each of them.

For practical matters: all outstanding gift certificates will be honored through June 30. Unused balances after that will be refunded by check — please email sarah@mainstreetbooks.com with your information. Our special-order pickups should be completed by June 25. The shelves will be on sale from June 1 forward.

Bookworm Bay on Oak Street will be taking over many of our standing orders, and I can't recommend them highly enough.

Thank you for 31 years. It's been everything.

With love, Sarah
