Plumber account growth: more accounts, and more of each account

Plumber account growth is marketing aimed at the counter: finding plumbing contractors who don't buy from you yet, and giving the ones who do a reason to put more of their spend on your invoices.

Written by Ali Sedighi, MBALast updated:

Plumber account growth is the service for supply houses that live on counter trade. It does two jobs at once: it puts you in front of plumbing contractors who don't buy from you yet, and it makes it easier for current accounts to give you more of their spend. Of the two, raising share is usually cheaper and faster.

Who it's for

This service fits wholesalers and supply houses with one or more branches where plumbers buy over the counter or by phone order. It suits you if:

  • most of your gross profit comes from residential service, repair and small renovation plumbers
  • you have branches in growing areas where newer plumbing shops don't know you
  • your top accounts buy from you, but also from two or three competitors
  • your reps spend more time chasing new names than deepening the accounts they have

It is less useful for a pure decorative showroom or a supplier that sells only through tenders. Those businesses should look at showroom marketing or project desk marketing first.

What's included

The work is built around three moments in a plumber's week.

Before the drive: being found

  • Branch listings that do the job. Every branch gets an accurate Google Business Profile with counter hours, early opening, will-call and delivery information, parking for trucks and the product categories you stock. A plumber searching from a job site at 6:45 a.m. should see that you are open.
  • Territory campaigns. Search and social campaigns aimed at plumbing businesses inside each branch's realistic drive time, built around the services that win trade accounts: early counters, after-hours pickup, delivery to site, credit terms.
  • Account-opening path. A short, clear page explaining how to open a trade account at each branch, what you need from the plumber, and who to call. Visitors reach your branch by phone, text or email.

At the counter: making the second visit easy

  • Printed and digital material that the counter team can hand to a new account, explaining reorder options and who their rep is.
  • A consent step at account opening, so new accounts can agree to receive stock and reorder messages.

Between visits: raising share

  • Truck-stock reminders. Consent-based messages built around the parts a service plumber restocks every week.
  • Category introductions. If an account buys copper and fittings from you but water heaters elsewhere, we build a campaign around the category they are missing.
  • Reporting by account tier, so your sales manager can see which accounts are growing and which are drifting.

Timeline

  • Weeks 1–2: account list review, share-of-wallet estimates for your top accounts, branch listing audit.
  • Weeks 3–6: branch listings rebuilt, account-opening pages live, first territory campaign running.
  • Months 2–3: reorder and category campaigns start with consenting accounts.
  • Month 4 onward: monthly review of new accounts, share movement by tier and campaign cost per active account.

New accounts can start showing in the first two months. Share of wallet moves more slowly; judge it quarter by quarter.

How results are measured

We agree on the definitions before any spend. Typical measures:

Measure How it's counted
New active accounts Accounts opened that place at least one order in 60 days
Share of wallet Your monthly sales to an account ÷ its estimated total material spend
Cost per active account Campaign cost ÷ new active accounts
Reorder rate Accounts ordering in two consecutive months

Website traffic and impressions appear in the report, but they are not the target.

Mistakes to avoid

  1. Chasing new accounts while ignoring share. An account at 15% share is a lead you already paid for. Work it first.
  2. Listing branches with office hours instead of counter hours. Plumbers buy early. If your profile says 8 a.m. and your counter opens at 6:30, you are invisible to your best customers.
  3. Buying contact lists for email campaigns. Under Canada's anti-spam law, commercial messages need consent you can prove, and bought lists damage your sender reputation too. Build consent at the counter instead.
  4. Measuring by clicks. A campaign that brings in homeowners instead of plumbers can look busy and produce nothing.

The share-of-wallet guide has a worksheet for estimating your top accounts. To see how this fits a monthly plan, look at pricing, or call, text or email.

Frequently asked questions

How do you measure share of wallet if plumbers won't tell us what they spend elsewhere?

You estimate it. Truck count, crew size and the type of work give a reasonable range for monthly material spend, and your sales reps can sense-check it. A rough estimate tracked every quarter is far more useful than no number at all.

Will you contact plumbers on our behalf?

Only through channels that respect CASL. Electronic messages need consent, clear identification and a working way to opt out, so we build consent into account opening and the counter rather than buying lists.

Does this replace our outside sales reps?

No. It feeds them. Marketing works hardest when it hands reps warm conversations to close; it should never try to stand in for a relationship.
