The cheapest sale is the next one to someone who already trusts you. This workstream sets up the routines that bring past buyers back: renewals, maintenance or service plans, timed check-ins, referral requests and, for larger accounts, a short account plan. It starts by about day 45 because repeat revenue builds slowly, and most of its payoff arrives after the sprint ends.
What the workstream is
Retention is the fourth figure in the revenue formula: how often a customer buys again. Most owner-led businesses never measure it. They know their best clients by name, but cannot say what share of last year's buyers came back this year.
We start by measuring it, then fix the obvious gaps. A customer who bought a service that needs annual attention should hear from you before the year is up. A business client who buys one product line should be offered the related one. A happy customer should be asked, once and clearly, whether they know someone else who needs you.
Who it is for
- Businesses with natural repeat cycles: service and maintenance, supplies, subscriptions, seasonal work.
- Business-to-business firms where the top 20 accounts make up most of the revenue.
- Any company with a customer list it has never really used.
What is included
- Repeat-rate baseline from the leak diagnosis, by customer type.
- Consent audit. Which contacts you may message and how, under Canada's anti-spam legislation, which covers commercial email and text messages.
- Renewal and plan offers, priced and packaged with the pricing tune-up.
- Timed check-in calendar. Who gets contacted, when and with what reason, built around your service cycle.
- Referral request. One clear ask at the right moment, usually just after a job is finished well.
- Account plans for the largest business clients: what they buy now, what else they could buy, and who decides.
Timeline
The consent audit and repeat-rate baseline are done by about day 40. Renewal offers and the check-in calendar go live between day 45 and day 60. The referral request starts once the sales routine is stable. Account plans for top clients are written in the last block, so the first conversations happen before the final readout.
A worked example
A business has 1,500 past customers from the last three years, of whom 900 have given consent to be contacted. Historically, 8% buy again in any year without being asked. A timed check-in that lifts that to 12% adds 36 repeat sales a year from the consented group alone. At an $800 average repeat sale, that is $28,800 a year, for the cost of a well-timed message and a person to answer replies.
Track it honestly: compare contacted customers with a small held-back group, so you know the lift came from the check-in and not from a busy season.
Who runs it after the sprint
The routines are designed for the people you already have. Typically one person owns the check-in calendar and spends an hour or two a week on it, answering replies and booking work. Account plans are owned by whoever looks after the client relationship. Everything is written down so it survives holidays and staff changes.
How results are measured
Repeat-purchase rate, renewal rate, revenue per customer per year and referrals received are tracked on the ledger. Where possible we hold back a small control group from each outreach so the effect can be read cleanly.
Mistakes to avoid
- Messaging contacts without consent. It risks penalties and damages trust.
- Sending the same offer to everyone. A customer who bought last month does not need a "we miss you" message.
- Asking for referrals at a bad moment. Ask when the customer is happiest, not when the invoice is overdue.
- Ignoring complaints in the list. A past customer with an unresolved problem should get a call, not a promotion.
The step-by-step approach is in the guide to winning back past customers. Then call, text or email to discuss your customer list.
Frequently asked questions
Can we email all our past customers?
Only those you have consent to message. Canada's anti-spam legislation covers commercial email and texts, and consent can be express or, in some situations, implied for a limited time. Check the official guidance and get legal advice if you are unsure.
Our customers only buy once. Does this apply?
More often than owners expect. Even one-off purchases usually lead to service, upgrades, add-ons or referrals. The diagnosis checks whether there is enough repeat potential to justify the work.
Why start retention so early in the sprint?
Because repeat revenue takes months to show. Starting around day 45 means the first returns appear before day 90 and the routine is running when we hand it over.
Do you run loyalty programs?
We prefer simple, low-cost routines such as timed check-ins and renewal offers over points schemes. If a loyalty program makes sense for you, we will help you judge it.
