Growth is a risk decision
Every new player is revenue and exposure at once. He adds to what the book can make in a year and to what it can lose in a week. Agents who think only about the first half are the ones who grow fast and close suddenly, usually through one of the mistakes that close books in their first year.
So the question is not how to get more players. It is how to add players while every week stays one you can pay and every player stays one you can see.
Keep the players you have
The cheapest growth is not losing anyone. A player who stays three years is worth more than three who stay a season, and he costs nothing to find.
Players leave for a short list of reasons. They were paid late. Nobody answered when they had a problem. The rules changed after they won. Or the site was awkward to use on a phone.
Three of those four are yours to control and take no money: pay in full on the same settlement day every week, answer the same day, and keep the rules the same in good weeks and bad.
Let players bring players
Most books grow by introduction. A player who is paid on time tells the people he bets with. That is the growth you want, because a new player arrives with someone who knows him.
It carries one obligation. The player who introduced him is not responsible for his balance, and you should not treat him as if he were. Give the newcomer the lowest limit you use and let him earn more.
Add in batches
Add five players, not twenty-five. Then wait about four weeks.
In that month you learn what matters about each of them: how often they bet, on what, whether they chase losses, and whether they pay on the day. Only after that do you add the next group.
It feels slow. It is the difference between knowing your book and hoping about it.
Grow the bankroll before the limits
This is the step that gets skipped. Every player you add increases the total your players could win in a single week. If the money you have set aside stays the same while that total rises, your cushion shrinks with every sign-up, even though nothing looks different.
Run the sum each time you add a batch. Add up the most every player could win in a week under their limits and compare it with what you hold. If the total has caught up with your bankroll, you have two honest options: put more money behind the book, or keep new players' limits low until you can.
Raising limits for good players is part of growth too, and the same sum applies. You can set limits by player, by sport and by bet type, so a raise can be narrow instead of across the board.
Know when you have stopped watching
There is a number of players beyond which you cannot hold the book in your head. It is different for everyone, and management writing has argued about the equivalent question for a century. The Wikipedia entry on span of control records the early assumption that no manager could supervise more than five or six direct subordinates, and later views that the right number depends on the work, with first-level supervisors handling up to thirty.
A book is not an office, but the point carries. Past some size, attention runs out. The signs are easy to spot: you are surprised by a player's balance, you cannot say who has been betting one side, or settlement day takes two days.
When that happens you need either fewer players or more people.
Delegate with a structure
The usual answer is a sub-agent: someone with his own players, his own limits and his own figures, sitting under you. You see everything and close with him, and he closes with his players.
It works when the sub-agent already knows the players he is bringing, and when the deal between you is written down before the first week. When to add sub-agents covers the timing and the terms. On the platform the structure lives in the agent tree, which is what lets a book reach a hundred players without one person tracking all of them.
Fill the quiet months
Growth is not only more players. It is also more weeks in which the players you have are active.
Sports have seasons. A book built on one sport has months when most of the list goes quiet. A casino and a racebook give players something to do in those months. Both are in the Standard plan on this platform. They change your risk as well as your revenue, so set limits for them before you promote them.
What growth does to the bill
Pay per head is billed per active player per week: Standard at $8, Pro at $11. The bill rises as active players rise and falls in quiet weeks, so it follows the size of the book without a fixed cost to outgrow.
If your volume becomes large, ask about pricing on the demo call. And remember what the fee does not include. BookiePerHead takes no wagers and holds no player money. The bankroll behind a bigger book is yours to provide.
An example
Take an agent, call him Gonzalo, with twenty-five players in Villa Lucero and a plan to reach sixty.
He adds six players a month, each at his lowest limit, each introduced by someone already on the book. Every month he reruns one sum, the most his players could win in a week, and twice in the year he holds off on new players because the total has reached what he has set aside. Both times he waits until he has added to the bankroll.
At around forty players he notices he no longer knows who bets every day. One of his oldest players has been bringing in most of the newcomers, so Gonzalo offers him a sub-agent deal, in writing, with his own eleven players.
It takes him fourteen months to reach sixty, not six. He never has a week he cannot pay.
A note on where you operate
A bigger book often means players in more places. Whether you may take bets depends on where you are and where each player is. Ask a lawyer who practises where you operate before you expand into somewhere new.
