What account mapping means
In B2B sales, account mapping is comparing your list of accounts with a partner's list to find the companies you both know. On each side, every account has a status: a customer, an open opportunity or a prospect. The combination of the two statuses tells you what to do next.
One note before you go further. "Account mapping" also means something in accounting: mapping one chart of accounts to another, for example when you move ledgers between bookkeeping systems. That is unrelated. This guide is about partner account mapping, the sales practice of comparing account lists with agencies, consultancies, resellers and technology partners.
Partner account mapping answers two questions you cannot answer alone:
- Which of my target accounts does this partner already know well?
- Which of my customers could help this partner, so they have a reason to help me?
The output is a short list of named accounts with an agreed next step on each, not a report.
The overlap matrix
Every overlap falls into one cell of a three by three grid: your status against the partner's status. Each cell has a different use.
| Your status | Partner's status | What it is good for |
|---|---|---|
| Prospect | Customer | Ask for a warm introduction. Usually your best bucket |
| Opportunity | Customer | Ask the partner for context and a good word with the buyer |
| Customer | Customer | Protect and grow the account: joint review, integration check, case study |
| Customer | Prospect | You can help them with an introduction or reference |
| Customer | Opportunity | Offer a reference call to help them close |
| Opportunity | Opportunity | Both of you are selling now. Agree who leads and consider co-selling |
| Prospect | Opportunity | Ask to be included in their proposal |
| Opportunity | Prospect | Low priority. Mention the partner to the buyer if it fits |
| Prospect | Prospect | Joint outreach, or park it. Neither side has a relationship |
The top rows are where you ask for something. The rows where you are the customer side are where you give something. Programs that only ask stop getting answers, so plan to act on both.
How to do account mapping by hand
You can run your first account maps with a spreadsheet. It takes an afternoon per partner.
- Agree the rules first. Before anyone exports anything, agree in writing what each side shares, what it will be used for, who sees it and when the files are deleted. An email both sides reply to is enough for a first exchange. If you have a partner agreement with a confidentiality clause, point to it.
- Export a minimal list. Each side exports company name, website domain and status. Nothing else.
- Clean the domains. Lowercase them and strip "www." and anything after the domain. Company names are spelled ten different ways, domains are not, so match on domain.
- Match the lists. One person, or a neutral third party if either side is nervous, matches the two lists on domain. In a spreadsheet that is a lookup of one list's domains in the other.
- Share only the matches. Each side sees the overlapping rows with both statuses, not the other side's full list.
- Agree a next step and an owner per account. Start with the five to ten best overlaps, not all of them.
What to share and what to keep back
| Share | Keep back |
|---|---|
| Company name | Contact names and email addresses |
| Website domain | Deal values and pricing |
| Status: customer, opportunity or prospect | Notes, call recordings and internal comments |
| Account owner's name, for matched accounts only | Your full account list, unmatched |
Contact details are the line most teams draw. They are personal data, they are the most sensitive thing in your CRM, and you do not need them to find an overlap. Once you agree to work a specific account together, the account owners can talk about who to approach.
Our account mapping template has sheets for both lists, the matched overlaps, a matrix that counts them and a table of next steps.
How to act on the results
An overlap list does nothing until someone owns each account. For each one you choose to work, decide three things: who reaches out, what they ask for, and by when.
Introductions. For your prospects who are the partner's customers, write a short note the partner can forward, with a specific reason the customer would want to talk. Asking the partner to "make an intro" with nothing to forward is the most common reason introductions never happen.
Co-selling. When you are both in an active sales cycle with the same account, agree who leads, what each side does at each stage and how each side gets credit. The co-selling guide covers the roles and the deal plan.
Attribution. Decide before the deal closes how it will be counted. An introduction that creates a new opportunity is usually partner-sourced. Help on a deal your team already had open is partner-influenced. The partner-sourced vs partner-influenced guide explains the rules, and getting them settled early avoids arguments at commission time.
Giving back. For your customers who are the partner's prospects, ask your account manager whether the customer would take a call. Offer it before the partner asks.
How often to refresh it
Statuses change every week. A prospect in last quarter's map may be a customer now, or an open opportunity may have been lost. A stale map sends reps after accounts that have already moved.
A workable rhythm:
- Monthly with your two or three most active partners.
- Quarterly with everyone else, ideally the week before each partner business review.
- Before any joint campaign, so the target list is current.
Each refresh, keep the overlaps you are already working, close out the ones that went nowhere, and add the new ones.
A worked example
You sell a reporting product to mid-market companies. Brightline Agency, a marketing agency in your program, agrees to map accounts with you.
- Your list: 400 accounts. 120 customers, 80 open opportunities and 200 target prospects.
- Brightline's list: 650 accounts. 300 clients, 50 open opportunities and 300 prospects.
- Matched on domain: 38 overlaps.
The 38 overlaps break down like this:
| Overlap | Count | What you do |
|---|---|---|
| Your prospect, their customer | 12 | Rank by fit, send intro notes for the top 8 |
| Your opportunity, their customer | 5 | Ask Brightline for context on each buyer |
| Shared customer | 9 | Pick 2 for a joint case study, check the rest for expansion |
| Your customer, their prospect | 6 | Offer Brightline introductions to 3 that fit |
| Both have an opportunity | 2 | Agree who leads, run as co-sell deals |
| Both prospects | 4 | Park until next quarter |
Now follow the first bucket. These are example numbers, not benchmarks. You send Brightline intro notes for 8 accounts. They forward 6. Four companies take a meeting, and two become opportunities at $15,000 a year each. That is $30,000 of new pipeline from one afternoon of matching. If Brightline is paid a 15% referral fee on first-year revenue and one deal closes, they earn $2,250, which is a reason for them to do it again next quarter.
Meanwhile the 5 open opportunities where Brightline already has the client are partner-influenced. If Brightline's word helps close even one of them, that deal ends sooner and with less discounting.
Common mistakes
- Swapping full lists. It creates a privacy problem and a trust problem, and nobody reads 650 rows. Share matches only.
- Matching on company name. "Atlas Logistics", "Atlas Logistics Inc." and "ATLAS" are three different names. Match on domain.
- Mapping without owners. If no one is named for each account, the list sits in a shared drive until the next quarter.
- Only asking, never giving. If every overlap you act on is an introduction you want, partners stop sharing.
- No attribution rule. Agree how sourced and influenced deals are counted before the first one closes. Conflicts with your own sales team are covered in the channel conflict guide.
- Mapping once. A map from six months ago is mostly wrong. Put the refresh in the calendar.
Account mapping without the spreadsheet
The spreadsheet method works for a handful of partners. With more, the time goes into exporting, cleaning domains and keeping each side's list private. Partner.io lets you upload a CSV of your customers, opportunities or prospects, or read them from your CRM, and shows which of your accounts overlap with each partner's, with a contacts view per matched company. When you want a partner to take an account, partner introductions let you send it to them as a lead, which they accept or reject in their portal.
