The work starts before the money does. You take the call, the matter sounds solid, the engagement letter goes out, and because you're busy and the client seems good for it, you open the file and get moving. The retainer is "on its way."
Then a week passes. You've put in three or four hours, the trust account still reads zero, and now you're in the awkward spot of asking a brand new client for money you've already started earning. Nobody enjoys that conversation, so it gets delayed, and the balance you're supposed to be drawing against stays empty while the file keeps moving.
Here's the thing worth fixing. The moment a client signs is the moment they're most willing to pay, because the decision feels fresh and the wallet is practically already out. If the request to pay shows up two days later in a separate email, you've missed that window and traded a clean deposit for a slow chase.
Why the gap keeps opening
A retainer (the up front deposit a client puts into your trust account so you can bill against it) is supposed to land before the work does. In practice the signature and the payment travel on two different tracks, and the signature almost always wins the race.
Some of it is sequencing. The engagement letter is one task and sending the invoice is another, and the two rarely happen in the same sitting. By the time you circle back to billing, the client has moved on to their day and the urgency is gone.
The rest is plain discomfort. Asking for money feels like it undercuts the goodwill you just built, so you let it ride and figure you'll square up at the first invoice. For a trust retainer that logic runs backwards, because the whole point of the deposit is to have the funds in hand before you spend time against them.
Put the payment link inside the signing moment
The cleanest fix is to make paying part of signing, not a step that comes after it. Most e-signature tools (the services that let a client sign the engagement letter on their phone) can either collect payment on the same screen or redirect straight to a payment link the second the signature lands.
A payment link is just a web page where the client types in a card or a bank account and pays you, with no login and no app to download. You generate one per matter, point it at the right account, and attach it to the engagement so the client sees "sign here" and "fund your retainer" inside the same two minutes.
When you set this up, keep it specific to the file:
- One link per matter, tagged so you know which file the money funds the moment it arrives.
- Both payment methods on: card for speed, and ACH bank transfer (a direct account to account payment) for the larger deposits where the card fee would sting.
- A clear label that says the money goes to trust, not to fees, so your records and the client's match from day one.
Let the reminders do the chasing
Some clients sign and pay in the same minute. Others sign, fully mean to pay, and then get pulled into a meeting. For that second group you want a reminder that goes out on its own, politely, every few days until the funds clear.
Set it to stop the instant the payment lands. Nothing erodes goodwill faster than a "friendly reminder" that shows up the morning after someone already paid, so the trigger has to watch the account and shut the sequence off automatically.
A cadence that works for most practices looks like this:
- Day of signing: the link, with a one line note that work begins once the retainer funds.
- Three days later: a short nudge if nothing's cleared yet.
- Every three days after that, two or three times at most, then it flags you to make a human call.
That last step matters. Automation handles the polite repetition, but a retainer that's still unpaid after a week or two is telling you something, and that's a conversation for you, not a fourth email from a robot.
Keep the trust account honest
If you're a Massachusetts law practice, the retainer goes into your IOLTA account (the pooled trust account lawyers here use for client funds), and the bookkeeping rules around it are strict. Automating the collection can't quietly automate you into a commingling problem.
Two guardrails keep this clean:
- Route retainer payments to the trust account directly, and have the processor's fees pulled from your operating account so client funds aren't nicked on the way in.
- Keep the record of what was paid and when attached to the matter automatically, so your three way reconciliation (bank, book, and client ledger) has a clean trail without you rebuilding it by hand.
Consulting practices have it a little easier, since a deposit usually just goes to your operating account. The sequencing advice is identical, the compliance weight is lighter.
Where this stops helping
A payment link won't make a client solvent, and it won't talk anyone into a number they can't afford. It moves the ask to the right moment, which is most of the battle, but it isn't magic.
It also won't replace your judgment on how big the retainer should be, or whether a given matter is worth taking at all. Those calls stay with you, same as always.
And it won't collect from someone who's decided not to pay. If a deposit is still sitting unpaid after the automatic nudges run out, the honest read is that you haven't really been retained yet, whatever the signed letter says. Better to learn that in week one, before you've put in ten hours, than in month two.
Worth doing this week
You don't need to rebuild your intake to get most of this. A few small moves this week do the real work.
- Check whether your e-signature tool can collect payment or redirect to a link on signing. Most can, and it's often a setting you've just never flipped.
- Set up one payment link that routes to your trust account, with both card and ACH turned on.
- Write the three line reminder sequence once, and set it to stop the moment a payment clears.
- Pick one new matter this week and run it through the whole thing, start to finish, as a live test.
- Decide your cutoff: how many days of unpaid retainer before you stop emailing and make a human call.
Get the deposit in before the first entry hits the clock, and the awkward chase mostly disappears. If you'd rather not wire the signing and payment steps together yourself, that's the kind of plumbing we set up for practices around here. Either way, fund the trust account first and let the billable hours follow.
