Most ecommerce founders assume selling their business is a 60 to 90 day project. The reality, for a healthy DTC or Amazon FBA brand priced correctly, is closer to five to nine months from the first conversation with a broker to wired funds in a bank account. The founders who close fastest are not the ones with the strongest business. They are the ones who treat the timeline as a sequence of seven defined phases, and start preparing six months before they list. Everyone else watches their deal slip into quarter three, lose its best buyer to fatigue, and reprice 10 to 20 percent below the original LOI.
This guide walks through every phase of an ecommerce sale, the realistic time each takes, what makes a deal move faster, and the friction points that blow timelines apart. The numbers below reflect deals in the $1M to $30M valuation range, which covers most Shopify and FBA exits.
Phase 1: Pre-sale preparation (60 to 120 days before listing)
The clock on a real ecommerce sale starts well before any broker engagement letter is signed. Pre-sale preparation is the period when a founder cleans up the financials, separates personal expenses from the P&L, locks down operational documentation, and begins building the data room a buyer will eventually request. Sellers who skip this phase pay for it later, when due diligence stretches an extra 30 days while a CFO scrambles to reconstruct three years of records.
What to document:
- Three years of monthly P&L by channel (Shopify, Amazon, wholesale)
- Bank statements and merchant processor reports tied out to revenue
- SKU-level cost of goods, landed cost, and contribution margin
- Vendor contracts, 3PL agreements, and any IP assignments from contractors
- A clean addback schedule with supporting evidence for every line
The most common pre-sale preparation issue: mixed personal and business expenses on the corporate card. Buyers do not refuse to credit legitimate addbacks, but they discount unsupported addbacks heavily, which can knock 0.3x to 0.5x off your final multiple.
Founders who use this phase well typically start it 90 to 120 days before they want a broker engagement signed. The result is a smoother engagement, a higher initial valuation, and a CIM that goes to market with the financials already buyer-ready. For a deeper view of what buyers will eventually examine, the DTC due diligence checklist covers the documents you will need to assemble.
Phase 2: Broker engagement and valuation (10 to 14 days)
Once a founder is ready to list, the engagement phase moves quickly. Broker selection takes a week of conversations and reference checks. The valuation work itself takes another five to seven business days, during which the broker reconciles the P&L, confirms addbacks, runs comparable transactions, and produces a defensible valuation range with the corresponding multiple.
What buyers and brokers examine in this phase:
- Trailing twelve months (TTM) revenue and SDE, normalized for one-time items
- Channel mix and the concentration risk associated with any single channel
- Year over year growth trend, particularly the most recent two quarters
- Inventory levels, ad spend efficiency, and any seasonality that would shift TTM
The single most common engagement issue: a founder pushing for a multiple that the comparable transaction data does not support. A broker who agrees to overprice the business simply to win the engagement is doing the seller no favors. The price gets reset 60 days later by buyer feedback, and that reset costs deal momentum.
A useful sanity check before signing is to look at the factors that drive ecommerce valuations against your own business. If three or four of the seven major drivers are weak, the multiple a broker can defend will be lower than you want, and that gap is better understood now than discovered in week eight.
Phase 3: CIM, teaser, and buyer outreach (3 to 6 weeks)
The CIM, or Confidential Information Memorandum, is the 30 to 50 page document that tells the story of the business. Drafting and approving it takes two to three weeks. Building the buyer list and running outreach takes another two to three weeks beyond that. A specialist ecommerce broker will typically reach 80 to 200 qualified buyers in this phase. Outreach to a thin or generic list is one of the most reliable ways to add 60 days to a deal.
What to document for the CIM:
- Brand origin story, market positioning, and category share
- Channel breakdown with growth, margin, and customer acquisition cost by channel
- Top SKUs, repeat purchase rate, and lifetime value by cohort
- Operations: supplier relationships, 3PL footprint, and team composition
- Three to five growth levers a buyer can credibly pull post-close
The most common CIM issue: a generic brand story with no proof points. Buyers see hundreds of CIMs a year. The ones that get a meeting are the ones with specific, data-backed claims: “61 percent repeat rate over 18 months,” not “loyal customer base.”
Sellers who are working with the right broker move through this phase quickly because the broker has already pre-built relationships with the relevant aggregators, search funds, family offices, and strategic buyers. To understand what an experienced broker actually does during this period, see working with an ecommerce broker.
Phase 4: Buyer calls and indications of interest (2 to 4 weeks)
Once the CIM is in market, qualified buyers sign NDAs and request management meetings. A typical schedule runs eight to fifteen calls over two to three weeks, after which serious buyers submit Indications of Interest (IOIs) with a non-binding price range and proposed deal structure. The seller and broker review IOIs together, narrow to two to four finalists, and invite those finalists to submit binding LOIs.
What to document going into management calls:
- A 25 to 35 slide management deck that mirrors the CIM but speaks more directly
- Concise written answers to the 15 to 20 most predictable buyer questions
- Channel and SKU performance dashboards in the data room, ready to share
- A script for the questions a founder should not answer on a first call
The most common buyer-call issue: over-disclosing on a first call. Founders who name suppliers, share unredacted customer lists, or reveal proprietary CAC numbers before an IOI is in hand give away leverage. Treat every call as a structured conversation, not a tour.
Phase 5: LOI negotiation (1 to 3 weeks)
When the seller selects a finalist, the buyer issues a Letter of Intent (LOI) with proposed price, structure, financing source, and a set of exclusivity and timeline terms. LOI negotiation moves in cycles of two to three days, with the broker driving redlines on the seller side. The most negotiated terms are price, working capital target, escrow, earnout structure, and the length of exclusivity.
What to document and lock in at LOI:
- Headline price, broken into cash, rollover equity, and earnout components
- Working capital peg with a clear definition of how it will be measured
- Escrow size and release timeline (typically 8 to 12 percent for 12 to 18 months)
- Treatment of inventory: included, separately purchased, or true-up at close
- Exclusivity period (45 to 75 days is standard) and any extension triggers
The single most common LOI issue: sellers focusing on headline price and ignoring structure. A $10M LOI with $4M in earnout tied to year-three EBITDA is not the same as a $9M LOI with $8M in cash at close. Run the present-value math on the structure before signing.
Deal structure becomes especially consequential at LOI because asset versus stock treatment, and the resulting tax outcome, can swing net proceeds by six or seven figures. The choice between an asset sale and a stock sale is rarely neutral, and the LOI is the right place to negotiate it.
Phase 6: Confirmatory due diligence (45 to 90 days)
Due diligence is the longest phase of any ecommerce sale and the phase most likely to derail the deal. The buyer’s team (often including a quality of earnings provider, an attorney, and an operations diligence partner) will request hundreds of documents, ask follow-up questions for six to ten weeks, and book recurring calls with the founder, the bookkeeper, and the head of operations.
What buyers will examine:
- Quality of earnings: revenue recognition, addback support, working capital normalization
- Customer data: cohort retention, repeat rate, refund behavior, top customer concentration
- Channel risk: Amazon listings health, ad account health, IP and brand registry status
- Operational diligence: supplier relationships, 3PL contracts, fulfillment SLAs
- Legal diligence: cap table, litigation history, IP assignments, customer privacy posture
The most common diligence issue: an unprepared seller who treats every buyer request as an interruption. Diligence drags on, the buyer loses confidence, and the deal repricing conversation begins. Sellers who respond inside 24 hours close 30 to 45 days faster than those who respond inside a week.
Sellers who treat the diligence period as a project, with a single point person responsible for triaging requests, finish faster and at a higher net price. Brokers help by routing routine requests, defending against scope creep, and pushing back on requests that should never have been made.
Phase 7: Definitive agreement and closing (2 to 4 weeks)
Once diligence is substantially complete, the buyer’s counsel drafts the Asset Purchase Agreement or Stock Purchase Agreement. Negotiation of representations, warranties, indemnification caps, and survival periods runs in parallel with final working capital calculations and the funds flow memo. Closing happens when signatures are exchanged, escrow is funded, and the wire is sent. From signed APA draft to wired funds, expect two to four weeks if both sides move quickly.
What to document and finalize before close:
- Final working capital schedule and any post-close true-up mechanism
- Disclosure schedules tied to every representation and warranty
- Transition services agreement, scope, and duration
- Employee and contractor consents, where required
- Domain, social handle, and platform account transfer plan
The most common closing issue: last-minute disclosure schedule disputes. Sellers who draft schedules early, with their attorney, avoid the standard 72-hour fire drill that pushes closing into the following week.
What compresses the timeline
Some factors are inside a founder’s control and can shave 30 to 60 days off the total timeline. The biggest is preparation: a seller who arrives with three years of clean monthly financials, a documented addback schedule, and an organized data room is ready to go to market in days, not weeks.
What shortens an ecommerce sale:
- Pre-built data room with bank-tied financials, contracts, and operational SOPs
- Realistic price expectations supported by current comparable transactions
- A specialist ecommerce broker with existing buyer relationships in your category
- Founder availability for diligence calls within 24 to 48 hours
- Clean cap table, no contractor IP issues, and no pending litigation
The compression rule: every week of diligence delay equals roughly 0.5 percent of valuation risk. Buyers reprice when momentum stalls. Founders who prioritize speed of response across diligence consistently close at higher net proceeds than founders who optimize for negotiating every individual data request.
What stretches the timeline
Most timeline blowouts come from a small number of recurring issues. Knowing them in advance is the cheapest way to avoid them. The single biggest cause of stretched ecommerce deals is timing: founders who decide to sell after a soft quarter, then watch the trailing twelve months slip while diligence runs, almost always face a price renegotiation.
What lengthens an ecommerce sale:
- Going to market on declining trailing twelve months without an explanation buyers will accept
- Heavy customer concentration (top 10 customers above 25 percent of revenue)
- Amazon account health issues, suspensions, or pending IP claims
- Founder dependency where the business cannot run for two weeks without daily decisions from the seller
- Tax structure complexity that surfaces only in diligence (multi-entity, foreign subsidiaries, unusual addbacks)
The single most common stretching issue: launching the process at the wrong time in the year. A DTC brand that goes to market in October walks into Q4 with buyers distracted and TTM data shifting under their feet. Aligning the listing to a calendar that gives buyers a clean post-Q4 view of the business is one of the highest-leverage timing decisions a seller will make.
The detailed thinking on this is in the guide on the right time to sell your ecommerce business.
A realistic timeline at a glance
Adding the phases together produces a defensible total range for a healthy ecommerce business that is properly prepared:
- Months 1 to 4: pre-sale preparation, broker selection, and valuation
- Month 5: CIM completion, buyer outreach, NDAs, and management calls
- Month 6: IOIs, finalist selection, LOI negotiation, exclusivity start
- Months 7 to 8: confirmatory due diligence and definitive agreement drafting
- Month 9: final working capital, disclosure schedules, signing, and closing
Sellers who prepared 90 to 120 days before engaging a broker can compress this to a six to seven month total. Sellers who skip preparation usually run nine to twelve months, with a meaningful chance of repricing along the way.
Bottom line
Selling an ecommerce business is not a fast process and any broker who promises a 60 day close on a multi-million dollar deal is selling a story, not a transaction. The realistic answer to how long to sell an ecommerce business is five to nine months from broker engagement to closing, with another three to six months of pre-sale preparation in front of that for sellers who want a clean, defensible exit.
The single highest-leverage decision a founder can make is treating preparation as the first phase of the sale, not a separate project. Sellers who spend 90 days getting the books, the data room, and the operational story buyer-ready close 30 to 60 days faster, see fewer repricing conversations, and walk away with materially higher net proceeds. The timeline is fixed by the structure of the deal. The outcome inside that timeline is fixed by how prepared the seller is when the process starts.
